TY - CPAPER T1 - Rural America in the 1980's: Choosing a New Agenda T2 - Rural Sociological Society AN - 61722003; 84S16685 AB - Changes in Ru SE conditions & in SE differences between Ur & Ru areas are reviewed. It is concluded that Ru growth & change during the last two decades have brought Ru areas into the mainstream of the nation's social & economic life & have diminished Ru-Ur differences. Hence, the appropriateness of past Ru policies focused on an agriculturally dominated, largely declining, persistently poor Ru sector is questionable. While a sensitivity to remaining unique Ru attributes & the great diversity within Ru areas is essential, it is concluded that Ru growth policy cannot be disconnected from national growth policy. To serve Ru areas, such a policy must focus on: (1) the Ru stake in macroeconomic policy; (2) the adequacy of public infrastructure; (3) program targeting to areas (& population groups) of greatest need; & (4) underdeveloped areas, whether Ur slums or persistent low-income Ru areas.

The procedure is an adaptation of the oxygen index (OI) fabric flammability test. Cellulose fibers or powders were pressed into 0.5-g discs, 1 1/4 in. in diameter which were used to measure the OI's in the instrument employed for fabric OI determinations. Comparison of OI's of discs and fabrics representing untreated and conven tionally treated FR cottons resulted in a linear relationship; disc OI values were higher due to higher fiber density and lower accessibility of oxygen to the substrate. Among the experimental treatments of cotton cellulose, OI values of fibrous and powdered celluloses were uniformly low with increasing tritylation, peaked and dropped with increasing tosyl concentration and rose with increas ing mesylation. Some derivatives would be considered flame resistant.

The Thps-urea-TMM flame retardant with added polyacrylate im parted better overall physical properties to 100% cotton fabric than to cotton blend fabrics. Treatments containing polyacrylates with low glass transition temperatures produced fabrics with the highest abrasion resistance, tearing strength and wrinkle recovery. The flame retardancy of treated fabrics was not adversely affected by the addition of polyacrylates to the flame retardant treatments.

The need for adequate state dam safety programs is stressed and some of the actions that the SCS (Soil Conservation Service) is taking are cited to support and encourage strong state dam safety programs. Policy statements have been issued by SCS declaring its support for strong state dams safety programs. Authority to deny assistance for installing new dams in a state that does not have, or is not moving toward, a strong program has been emphasized. SCS also has the authority to require local people or the state to develop Emergency Action Plans for new Class c (high hazard) dams. SCS also has the power to require specific notifications in regard to land use downstream of Class a and b (low- and moderate-hazard) dams.

Fifteen erosivity factors were regressed to ascertain best fit on the soil loss from 3 fallowed plots for each of 35 storms between March 1982 and April 1983. Two of the best rainfall erosivity factors with their respective coefficients of determination are: total kinetic energy times maximum 30-min intensity (EI sub 30), r squared = 0.69, and rainfall amount times the maximum 30-min intensity (AI 30), r squared = 0.72. A regression equation was developed relating EI 30 to rainfall amount, A. The coefficient of determination was 0.902. Soil erodibility for this Alfisol was found to be 0.0314 tonne hectare hour per hectare megajoule millimeter or 0.24 in customary English units. Erodibility factor values ranged from 0.07 for storms producing soil losses less than 1 t/ha to 0.55 for storms producing soil losses greater than 10 t/ha.

Rates of water loss were dependent upon temperature and saturation deficit with evidence of an ability of both species to exercise some control over loss rates under increasingly stressfull conditions. Rates of water loss of both species were comparable to those of other xeric-adapted insects on a loss per unit of surface area-specific basis.

AN - 14436906; 1355034 AB - Tissues were homogenized and then deproteinized with acetonitrile. The acetonitrile extract was partitioned between dichloromethane and pH 2.2 buffer and then extracted with pH 7 buffer. After addition of ammonium sulfate to the aqueous solution, it was mixed with acetonitrile. The acetonitrile extract was separated and evaporated, and the residue was taken up in water. The aqueous solution was analyzed by high-performance liquid chromatography (HPLC) on a C sub(18), 10- mu m particle size, reversed-phase column using gradient elution with 0.01 M orthophosphoric acid-acetonitrile (from 80:20 to 40:60 in 20 min) at a flow-rate of 1 ml/min and UV absorbance detection at 220 nm. Recoveries were generally greater than 90% with all tissues. Data on incurred residues from a treated cow showed recoveries of penicillin which were frequently several times higher by HPLC than by bioassay. Sensitivity limits in muscle were about 0.05 ppm for both penicillin G and cloxacillin, but higher in liver and kidney because of interferences. The method is suitable for other monobasic penicillins but not for dibasic or amphoteric penicillins.

This procedure provided evidence that this species can receive sufficient pollen for pollination by wind alone, although both insects and wind are factors in pollen distribution under optimal weather conditions.

AN - 14364016; 1185823 AB - Acholeplasmas, spiroplasmas and other non-helical sterol-requiring mycoplasmas of unknown phylogenetic affinity inhabit insects. Of these, only spiroplasmas are known to be pathogenic. Group 1-2 spiroplasmas, or Spiroplasma apis , especially in combination with other organisms, reduce honey-bee longevity. Plant pathogenic mycoplasma-like organisms are often found intracellularly in insects. Spiroplasmas are found predominantly in the gut lumen or haemolymph (or both) of their insect hosts. Pathogenicity of mycoplasmas is usually altered by extended passage in unusual hosts, in only one of two alternate hosts, or in culture media. Enhancement of experimental pathogenicity may occur with extended cultural passages, but maintenance of natural pathogenicity must be accomplished by continuous exposure to the usual host. JF - ANN.

I. Model development. AN - 14342423; 1175974 AB - A model has been developed for calculating consumptive water use of subalpine forests in the Rocky Mountains. This model, RM-CWU, is based upon the use of a submodel of stomatal behavior in which stomatal activity is predicted from photosynthetic photon flux density (PPFD) and the absolute humidity difference from leaf to air (DAH). Instantaneous transpirational flux density is calculated for layers of leaf area for each species, and transpiration is summed for the entire canopy. PPFD profiles are derived using extinction coefficients estimated for each stand, for a range of sun angles along with estimates of PPFD above the canopy corrected for slope, aspect, obstruction of the horizon, time, and date. DAH is estimated from records collected at a centrally located weather station, using a submodel for calculating canopy temperature at higher elevations. In preliminary applications, conductances calculated with RM-CWU varied with physiographic features of the site, date and time, position in the canopy, and weather conditions, through effects on PPFD and DAH. Consumptive water use, calculated for entire stands using leaf areas predicted from basal area measurements, also varied with stand composition. JF - CAN. J. FOR. RES.

AN - 14328209; 1147670 AB - Organic content of the forest floor decreases for several years after clear-cutting, and then slowly recovers. Thickness, bulk density, organic matter, and nitrogen content of forest floors were measured for 13 northern hardwood stands in the White Mountains of New Hampshire. Stands ranged from 1 to about 100 years in age. Forest-floor thickness varied significantly with stand age, but bulk density, organic fraction, and nitrogen franction were independent of age. Total organic content of the forest floor agreed very well with data from Covington's (W. W. Covington 1981. Ecology, 62:41-48) study of the same area. Both studies indicated that mature forest floors have about 80 Mg organic matter multiplied by ha super(-1) and 1.9 Mg nitrogen multiplied by ha super(-1). Within 10 or 15 years after cutting, the organic matter content of the floor decreases to 50 Mg multiplied by ha super(-1), and its nitrogen content to 1.1 Mg multiplied by ha super(-1). JF - CAN. J.

AN - 14323542; 1147780 AB - Although erosion-hazard ratings are often used to guide forest practices, those used in California from 1974 to 1982 have been inadequate for estimating erosion potential. To improve the erosion-hazard rating procedure, separate estimating equations were used for different situations. The ratings were partioned according to yarding method, erosional process, and both yarding method and erosional process. Partitioning by yarding method resulted in a slight improvement in the precision of erosion estimates. The other two methods resulted in fourfold increases in prediction errors. Results indicate that a single unified erosion-hazard rating procedure is the most practical way of predicting logging-related erosion in northwestern California. JF - CAN. J. FOR. RES.

I. Energy balance considerations related to surface albedo. AN - 14315913; 1128125 AB - An analysis of northern, low and southern latitude temperature trends of the past century, along with available atmospheric CO sub(2) concentration and industrial carbon production data, suggests that the true climatic effect of increasing the CO sub(2) content of the atmosphere may be to cool the Earth and not warm it, contrary to most past analyses of this phenomenon. A physical mechanism is thus proposed to explain how CO sub(2) may act as an inverse greenhouse gas in Earth's atmosphere. However, a negative feedback mechanism related to a lowering of the plant's mean surface albedo, due to the migration of more mesic-adapted vegetation onto arid and semi-arid lands as a result of the increased water use efficiency which most plants experience under high levels of atmospheric CO sub(2), acts to counter this inverse greenhouse effect. Quantitative estimates of the magnitudes of both phenomena are made, and it is shown that they are probably compensatory. This finding suggests that the author will not suffer any great climatic catastrophe but will instead reap great agricultural benefits from the rapid increase in atmospheric CO sub(2) which he is currently experiencing and which is projected to continue for perhaps another century or two into the future.

Injury was also dependent on acetate concentration and pH; equivalent phosphate buffers did not produce an injury response. Cells pre-exposed to acid acetate buffer at 20 degree C and then placed in pH 7.0 acetate buffer at 40 degree C were injured, but no injury occurred in cells not previously exposed to acidic conditions when placed in neutral buffer at 40 degree C. Acetate (0.2 M) blocked glucose utilization in 20 degree C and 40 degree C incubated cells at pH 4.4, but not at pH 6.1. Glucose was metabolized by S. aureus in phosphate buffer at both pH 4.5 and 6.0. JF - LEBENSM.-WISS. TECHNOL.

AN - 14244127; 1075496 AB - The interaction between Cytospora leucostoma (causal agent of peach canker) and host-phenolic compounds in dormant peach trees (Prunus persica (L.) Batsch) was examined. Initially, inoculated samples had significantly higher phenolic levels than uninoculated samples. The levels in inoculated samples decreased dramatically in tissues closest to the point of inoculation, however, while the phenolic levels in uninoculated samples remained relatively stable through time. The data C. leucostoma degraded host-phenolic compounds. Maximum phenolic enrichment was observed in the branch collar region of the main stem of inoculated samples. It was concluded that the presence of C. leucostoma in host tissue played a significant role, over and above the wounding response, in establishing levels of host-phenolic compounds. JF - J. AM.

AN - 14224096; 1049285 AB - Effects of low soil temperature on the water relations, shoot growth, and root growth of Douglas-fir seedlings (Pseudotsuga menziesii (Mirb.) Franco) were studied to evaluate the significance of reduced water uptake and growth in seedlings outplanted in cold soils. Low soil temperature reduced shoot growth and completely prevented root growth. The results indicate that for seedlings planted in cold soil, reduced water uptake does not immediately cause lethal water stress. The primary cause of poor field survival probably is suppressed root growth at low soil temperature resulting in increased susceptibility to summer drought.

AN - 14221232; 1049303 AB - A long-term study of the effects of season-long and deferred rotation grazing at different stocking rates examined cow and calf weight gains. Optimum stocking rates for season-long grazing on ponderosa pine-bunchgrass range were found to be moderate or light over a wide range of feasible price ratios. Optimum stocking rates for deferred rotation grazing did not exceed a moderate level at any feasible price ratio. The ratio of forage price (S/AUM) to the price of livestock (S/kg) must exceed 11 under deferred rotation grazing and 18 under season-long grazing before light stocking becomes the optimum. To remain at the profit maximizing stocking rate while shifting from season-long to deferred rotation, a manager would have to reduce the stocking level at all price ratios.

AN - 14203885; 1026893 AB - Procedures for encapsulating seed of various pine species with basidiopores of P. tinctorius were developed. In container tests in 1979 with Pinus taeda, P. virginiana, P. elliottii var. elliottii, P. echinata, P. oocarpa , and P. caribaea , seed encapsulation with spores increased seed diameter by 1.5 mm and decreased seedling establishment by up to 60 percent. Only moderate amounts of Pisolithus ectomycorrhizae developed on most tree species. However, abundant P. tinctorius ectomycorrhizae were developed in 1980 on P. taeda seedlings in both containers and in microplots by using a coating that increased seed diameters by only 1 mm and by adjusting the watering schedule. Encapsulation with 1 or 2 mg of spores per seed reduced seedling establishment by 20 percent in microplots; 1 mg spores per seed did not reduce seedling establishment in containers. One mg of sproes per seed was as effective as 2 mg of spores per seed in forming Pisolithus ectomycorrhizae.

Incompatile (HR-inducing) races of P. syringae pv. glycinea and a non-HR-inducing strain of the heterologous pathogen Corynebacterium flacumfaciens pv. flaccumfaciens showed more restricted growth. Incompatible races of P. syringae pv. glycinea and the heterologous pseudomonads induced accumulation of isoflavonoids (daidzin, formononetin, genistein, glyceollin) and isoflavone glucosides (daidzin, genistin, ononin). Immobilization of bacteria by highly electron-dense material in intercellular spaces of soybean leaves occurred to the greatest extent with E. carotovora subsp. atroseptica and B. cereus , and to a lesser extent with C. flaccumfaciens pv. flaccumfaciens .

The properties of the solubilized ATPase were found to be similar to the membrane-bound enzyme with respect to pH optimum, substrate specificity, inhibitor sensitivity, and kinetics of K super(+) stimulation. The solubilized ATPase preparation formed a rapidly turning over phosphoenzyme, the breakdown velocity of which was increased in the presence of 50 millimolar KCl. Solubilization following extraction resulted in an increase in both ATPase activity and steady state phosphoenzyme level. JF - Plant Physiology AU - Briskin, D P AU - Poole, R J AD - Plant Biochem.

AN - 14164784; 983380 AB - As a means of developing reliable estimates of ecosystem productivity, landscapes need to be stratified into homogeneous geographic regions. Such ecosystem regions are hypothesized to be productively different in important ways. One measure of the difference is hydrologic productivity (i.e. runoff per unit area). To test the hypothesis that hydrologic productivity is significantly different from region to region, data from 53 hydrologic bench-mark stations within major ecosystem regions of the conterminous United States were subjected to discriminant analysis. The ecosystem regions tested in this study exhibit a high degree of ability to circumscribe stations with similar hydrologic productivity. Discriminant analysis seems to be particularly appropriate method for testing the validity of land units at all scales of interest.

AN - 14163781; 983442 AB - In a continuing search for field sources of endomycorrhizal fingi that tolerate high levels of available phosphorus in soil, samples were obtained from long-established liberally fertilized hops (Humulus lupulus L.) and peppermint (Mentha piperita L.) fields. Vesicular-arbuscular mycorrhizal (VAM) fungi were found colonizing most roots to some extent, despite the very high fertility of several sites. Curiously, considerable external VAM hyphae were found adherent to or entangling roots in many cases, even where percentage of root length with internal VAM structures was low. The functional benefit, neutrality, or detriment to plants of such high-P tolerant species remains to be determined. JF - PLANT AND SOIL.

The authors examined the hypothesis that activated oxygen species are involved, and they also sought the agent in ligninolytic cultures responsible for a specific oxidative degradative reaction in substructure model compounds. The actual biochemical agent responsible for one important oxidative C-C bond cleavage reaction in non-phenolic lignin substructure model compounds, and in lignin itself, was found to be an enzyme. The enzyme is extracellular, has a molecular weight of 42,000 daltons, is azide-sensitive, and requires H sub(2)O sub(2) for activity.

AN - 14133321; 947511 AB - Relationships between the abundance of 2 quail species and range site and grazing management during drought were evaluated in the northern Rio Grande Plain of Texas. Clay loam range sites provided better nesting cover and greater abundance of forbs for quail than sandy loam and shallow ridge range sites. Foliar cover and aboveground standing crop of grass were greater on the 3 range sites within the short duration and deferred rotation systems as compared with the yearlong system. During drought, grazing systems provided better nesting and protective cover for quail than yearlong grazing.

AN - 14123265; 945772 AB - Oat stem rust was present in trace amounts in the southern United States in 1983. Disease development was generally a week later than the 40-yr average. Losses were light throughout the United States. No isolates were obtained from Mexico. The principal race was NA-27, virulent on host genes Pg-1, -2, -3, -4 , and -8 , making up 88% of the isolates. No virulence was found in oat stem rust for host genes Pg-13, 16 , or -a . Wheat stem rust was found in trace amounts in southern Texas in mid-March. Stem rust spread northward into the northern Great Plains by mid-June. Although moderate severities occurred in some hard red spring wheat fields, the cultivars had adequate resistance to prevent the massive inoculum levels of the mid-1950s and losses were minimal. Race 15-TNM, virulent on Sr17, was the most common virulence combination, making up 70% of the 1,295 isolates from 466 collections. The second most common race was Sr17 avirulent on 15 TNM, which made up 24% of the isolates. JF - Plant Disease AU - Roelfs, A P AU - Casper, D H AU - Long, D L AD - Dep.

AN - 14122953; 946589 AB - Conditions for maximizing detection of a California isolate of beet western yellows virus (BWYV) were investigated with the double-sandwich enzyme-linked immunosorbent assay (ELISA) system. Within-plate variability was found to account for less than 1% of the total variation observed on individual microtiter plates. Variability across plates was greater than within plates and accounted for less than 10% of the total variation. Efficient extraction of virus from host and vector tissues increased absorbance. Carborundum added to the extraction buffer worked well when tissue samples were ground in a mortar and pestle but highest absorbance resulted when test samples were prepared with a high-speed tissue homogenizer. Background levels were unacceptably high when 10 or more Myzus persicae were pooled for analysis. Since virus can be detected in 3 or even 1 aphid, pooling for detection is unnecessary. Optimization of the BWYV ELISA system made possible the detection of virus quantities less than 2 ng/ml. JF - Journal of Virological Methods AU - Hewings, AD AU - d'Arcy, C J AD - USDA-ARS Plant Dis.

AN - 14107355; 930798 AB - Commercial dry lipase from Candida rugosa (formerly C. cylindracea ) was used to catalyze hydrolysis of tallow, coconut oil and olive oil at 26-40 C. A methodology was developed to yield results reproducible within plus or minus 10% and to achieve essentially complete hydrolysis. From the hydrolysis data, an empirical relationship was developed that shows that the percentage of free fatty acid formed is almost a linear function of the logarithm of reaction time and the logarithm of enzyme concentration. A 95-98% hydrolysis of the 3 substrates was achieved experimentally in 72 hr, requiring 15 units lipase per milliequivalent (U/meq) of coconut oil or tallow and 6 U/meq of olive oil.

The quantities of added selenium that were transferred from cigarettes to inhaled, mainstream smoke were examined for several commercial and experimental cigarettes of different tar levels. For high-tar cigarettes, as much as 10% of added selenium was found in mainstream smoke, while low-tar cigarettes, delivered about 3% of added selenium. Transfer rates of selenium to mainstream smoke are reported for various levels of fortification and the rationale for selenium fortification is discussed. Based on highly favorable reports in the literature on the antitumor activity of selenium, the fortification of tobacco with selenium may become a viable way of producing a safer tobacco product. It is proposed that such selenium-fortified smoking products be developed and evaluated extensively. JF - Archives of Environmental Health AU - Chortyk, O T AU - Schlotzhauer, W S AD - Tobacco Saf.

AN - 14092742; 923514 AB - Antisera specific for leucine aminopeptidase (LAP) were prepared. Using these antisera in immunodiffusion tests, the identity of LAP isolated from beef lens and kidney is demonstrated. The same pertains to hog lens and kidney LAP. As indicated by only partial fusion of the immunoprecipitates in immunodiffusion plates, leucine aminopeptidases isolated from hog and beef are antigenically similar but not identical. These tests also indicate substantial similarity between a component in human lens homogenates and bovine or hog LAP. The data establish that LAP is a species-specific enzyme and they indicate that it is not organ specific.

AN - 14086098; 897468 AB - When all above-stump parts of southern pine trees are harvested, only 16 to 22 percent more biomass is obtained than in conventional harvests. Its harvest doubles the removal of certain important soil nutrients. When hardwood stands are total-tree harvested, the additional biomass yield is 30 to 100 percent higher than in conventional harvests, and the quality of biomass for fuel and fiber is above that for pine stands. Nutrient drain for hardwood stands logged by total-tree methods is 2 to 3 times that in conventional harvesting. Total harvesting has made many hardwood stands operable that previously were not, thereby increasing the silvicultural opportunity to improve the stands.

AN - 14082137; 897682 AB - Of the 403 exotic and 631 commercial, unreleased, and parental sweet sorghum lines field-tested for resistance to rough leaf spot disease at Meridian, MS, only two lines (MN 3344 and MN 4055) showed a high level of resistance in 1981 and 1982. MN 4055 remained completely free of the disease. MN 3344, which was introduced from India as PI 201754, showed only slight infection. No other lines showed good resistance to the disease. With a projected increase in grain sorghum production in Mississippi, the identification of sources of resistance to rough leaf spot disease in sweet sorghum will be of value to the grain sorghum industry.

Females of both species emerged 4 or 5 days earlier than males. Synchrony between the spring emergence of male TBW and their capture in pheromone traps demonstrated the feasibility of using pheromone traps to monitor overwintering emergence. On the other hand, asynchrony between the capture and emergence of BW males indicated that movement of the species into the area may occur before emergence from overwintering.

Spoils with herbaceous cover tended to have the highest nitrifying, denitrifying and other bacterial populations. Soil fungal populations on these herbaceous sites approached those on undisturbed pine forest sites. The fungal genera Aspergillus, Chaetomium, Verticillium and Fusarium were more common on the herbaceous sites than on sites with other vegetative covers. Oidiodendron were isolated more frequently on spoils supporting pine species. Further study of the effects of reclamation practices on microbial populations and processes involved in nutrient cycling on kaolin spoil is suggested by such populations on spoils with herbaceous cover.

AN - 14070590; 893560 AB - A virus 30 nm in diameter and serologically related to the tomato aspermy virus (TAV) type strain was isolated from volunteer tomato plants in Prince George's County, MD. The isolate has been designated TAV-M. Spinacia oleracea "Bounty" (spinach) was a suitable propagative host, yielding 1-5 mg of virus per 100 g of leaf tissue 12-14 days after inoculation. Chenopodium quinoa was a reliable assay host, producing necrotic local lesions 6-9 days after inoculation. The longevity in vitro of TAV-M was between 30 and 48 hr at 25 C, the thermal inactivation point was between 60 and 65 C, and the dilution end point was between 10 super(-4) and 10 super(-5) in Bounty spinach. TAV-M did not produce enations typical of TAV of fruit aspermy in tomato plants but temporarily inhibited growth and caused a mild leaf mottle of inoculated seedlings.

Globules contained within the scales stained with Sudan IV, a lipophilic dye. Essential oil contents of the scales varied with species from 24 plus or minus 8 to 151 plus or minus 35 ng/scale. Black vine weevil Otiorhynchus sulcatus) feeding on leaves from a sample of rhododendron species was inversely related to leaf essential oil content, and weevil feeding on membrane filters was inhibited by application of essential oil extracts from leaves of most lepidote rhododendrons tested. Results suggest that the glandular scales of the lepidote rhodoendrons function, at least in part, in plant defense against insects.

The method is illustrated using data collected on several treatments in the Yampa River Basin coal fields of northwestern Colorado. The field studies used a CSU type portable rainfall simulator.

AN - 14060034; 877749 AB - The effects of dietary methionine (Met) on the toxicities of methylmercury hydroxide (MeHg) and atrazine in male Wistar rats were investigated. Excess dietary Met had a protective effect on MeHg and atrazine toxicities when weight gain was used as the index of toxicity. Liver weight in response to toxicants was increased in the rats fed lower Met level. Data suggest that Met deficiency, in response to both toxicants, depressed weight gain while increasing deposition of Hg in tissues, increased liver GSH S-strans in presence of atrazine, and, in presence of high MeHg, decrease liver GSH-S-trans. Supplementation with Met, in contrast, depressed weight loss, liver weight, and deposition of Hg in tissues, and prevented depression of blood GSH-Px activity. An adaptive process may exist in the rat to prevent depletion of tissue GSH during chronic exposure to GSH-depleting agents. Dietary Met supplementation may not lessen the potentiation of MeHg toxicity caused by atrazine (at the level we used). JF - DRUG. NUTR. INTERACTIONS.

AN - 14055774; 862891 AB - Alfalfa mosaic virus (AMV) were eradicated from tubers of greenhouse- and field-grown Russet Burbank Potato by hot-air treatment at 37 C for 4-5 wk. Virus could not be detected by repeated inoculation of susceptible test plants or by gel immunodiffusion tests in plants arising from these heat-treated tubers. Heat treatment effectively eliminated AMV from all sizes of tubers tested. Survival of heat-treated tubers after 4 and 5 wk was greater than or equal to 60% regardless of tuber size. The virus also was eliminated from shoot tips of AMV-infected plants after 6-8 wk of exposure to alternating temperature regimes. Exposure of whole virus-infected plants to such treatment for 6-14 wk caused temporary remission of virus symptoms; however, plants were still infected with AMV after removal from the elevated temperatures.

Two growing seasons after the 1st treatment, total honeysuckle yield (kg/ha) was greatest on controls and least on burned plots. One and two growing seasons after the 2nd treatment, yield on the mowed plots was significantly greater than that on the control or burned plots. However, honeysuckle formed large, solid mats on control and mowed plots duet to the numerous, intertwined runners, while burning reduced the dence growth between plants making them accessible to white-tailed deer (Odocoileus virginianus ).

AN - 14054652; 875775 AB - A 36-yr old species adaptations test was evaluated and the relative quality of some persisting native and introduced grasss species was determined. The site was Conlen loam on the Rita Blanca National Grassland in Dallam, County. Texas. Of the 25 species planted, only yellow bluesterm (Bothriochloa ischaemum ), Caucasian bluestem (Bothriochloa caucasica ) and galleta (Hilaria jamesii ) tended to dominate the plots on which they were originally planted. Yellow and Caucasian bluestem had spread into plots planted to other grasses but galleta had spread very little. The contents of Caucasian bluestem and galleta were not significantly different from those of yellow bluestem, except that galleta was lower in IVDMD, especially when mature. These 3 grasses merit considerations in range seeding programs on Conlen and similar soils in the Southern High Plains.

AN - 14054293; 876006 AB - A 7-year study was conducted on forage yield, digestibility, and crude protein of 7 species of grass, 3 cultivars of alfalfa, and cicer milkwetch at Sidney, Mont., from 1975 through 1981. Forage quality was inversely proportional with forage yield. Crude protein concentration of legumes and grasses decreased 0.8 and 1.25 percentage units, respectively, while dry matter digestibility decreased 1.5 to 2.3 percentage units per every 1,000 kg/ha increase in forage yield. Meadow bromegrass and reed canarygrass produced the least forage from the second through seventh years of the study. Neither forage yield nor quality differed among the 3 creeping-rooted alfalfas: "Rambler", "Drylander", and "Orenberg". Russian wildrye, Altai wildrye, and green needlegrass produced the most forage during the 1980 drought, and the alfalfas, pubescent wheatgrass, and meadow bromegrass produced the least. Cicer milk-vetch and reed canarygrass died during the 1980 drought. Forage digestibility of the alfalfas was 5 to 6 percentage units higher than that of the grasses, and the alfalfas also produced more digestible forage per unit of land. The crude protein concentration of alfalfas was almost twice that in grasses, and alfalfa produced almost twice as much crude protein per unit of land (kg/ha).

AN - 14054249; 875269 AB - Winter damage and the subsequent number of viable leaves at the beginning of growth in spring were highly correlated with spring and fall seedling growth in crested wheatgrass, Russian wild ryegrass, and pubescent wheatgrass. As spring leaf numbers on individual plants increased from one to four, there was a corresponding increase in subsequent growth. As winter injury increased, seedling growth was reduced. These results suggest that late-summer seeding in the Northern Great Plains would hasten stand establishment and reduce the length of grazing deferment on newly seeded stands.

Liquid-liquid extraction followed by gas chromatography-mass spectrometry or electron capture gas chromatography was used to analyze for pesticides with low volatility. The authors have validated these methods for a series of pesticides that have been extensively used in agriculture in the southeast. Over a 3-year period, the only detected organic pesticide in groundwater obtained from three different irrigation wells was ethylene dibromide (EDB). The concentration of this compounds was determined by calibration against benzene-d sub(6). The concentration of EDB varied between 1 and 94 mu g/L.

AN - 14044478; 877244 AB - To assess the potential effect of cyclopiazonic acid (CPA) on pregnancy and fetal development, Fischer-344 rats were dosed daily with 0, 1, 5, or 10 mg CPA/kg body weight on either d 8-11 or d 12-15 of pregnancy. Animals that diet had histologic lesion in the liver, spleen, kidney, and other organs. Compared to controls, there were no significant differences in pup weights, percentage pre- or postimplantation losses, or fetal deaths. Significant differences in skeletal development included retardation of ossification of cervical centra (d 12-15) and caudal vertebrae (d-11) in the two highest dose groups. Retardations of development were the most common manifestations of embryotoxicity.

AN - 14042655; 867057 AB - Serial dilution of basidiospores of a spore print to prepare grain spawn of the Oyster mushroom is described. The method, which has a contamination rate of about 5%, requires sterilization of a grain medium and the use of some simple "clean" procedures. The method is especially advantageous for small scale and part-time cultivation of mushrooms on logs. Pleurotus ostreatus Kumm. mycelium grew rapidly into the wood of freshly cut logs inoculated with disks of grain spawn prepared using spore inoculom. Unlike pure-culture spawn disks, however, disks prepared from spore-inoculated grain did not become completely tightly bonded to the wood surface.

They were either untreated or inoculated with Staphylococcus aureus) or Clostridium sporogenes and incubated at a moderate abuse temperature of 11 degree C for up to 11 days. A slightly more rapid growth of the natural flora was noted in the frankfurters containing 60% of the normal salt compared to those containing higher levels of salt. No outgrowth of clostridial spores occurred in any inoculated sample. Staphylococcal growth was slow and inconsistent, with no effect related to salt levels. Incubating frankfurters at higher temperatures showed that abuse temperature had a greater effect on total aerobic and staphylococcal growth than did the salt levels tested.

AN - 14041528; 875425 AB - Gullies with large reliefs, 15 to 20 feet, were accurately mapped with time-lapse aerial photographs. Contour maps (0.5-foot) of the gully area provided a general study of changes in the valley floor, headcut, and gully erosion by overlaying successive topographic maps. Plotting individual cross-section points achieved the desired accuracy of plus or minus 0.05-feet for surveys on bare ground. Sheet and rill erosion also were determined to the same accuracy with low-altitude, time-lapse aerial photographs. Soil movement was determined for each stereomodel and algebraically summed. Net, 9-year soil erosion was 130 tons/acre, resulting in average annual erosion of 14 tons/acre. Average annual sediment delivery ratio of 53% was determined using the 7.7-ton-per-acre average annual sediment yield for the 75-acre watershed. Universal soil loss equation calculations predicted an annual soil loss of 37 tons/acre, resulting in a sediment delivery ratio of 21%.

AN - 14039787; 855667 AB - Genotype, environment, and genotype x environment interaction effects for forage yield and quality of the crested wheat grasses (Agropyron cristatum ) and (A. desertorum ) were studied using an array of 42 crested wheatgrass introductions, experimental lines, and released cultivars that were selected to be representative of the mix of germplasm available to a breeder. They were grown in two environments, Lincoln and Alliance, Nebr., that differ markedly in climate. Forage yield and forage quality as measured by in vitro dry matter digestibility (IVDMD) and percent protein were determined in both locations in 1980 and 1981. The results indicate that existing genetic variability in forage yield and quality should permit the development of improved crested wheatgrasses and that at least in the initial stages of a breeding program, selection for these traits could be done in a single location and year.

AN - 14036540; 863797 AB - A rapid method for measurement of lactic acid in refrigerated ground beef was developed using high performance liquid chromatography (HPLC) with an Aminex HPX-87H ion exclusion column. The method was compared with an existing gas chromatography procedure. Nine samples of ground beef, consisting of three grades based on fat content, were tested over six days of aerobic and two weeks of a anaerobic storage. No significant difference was found in reproducibility between the two methods as measured by their variance. There also was no significant difference between the variances for grade of beef or for duration of aerobic or anaerobic storage. The following equation was developed to relate the two methods: GC = -138.43 + 1.1254 (HPLC).

(Reg. no. 91), developed and released cooperatively by the USDA-ARS and the North Carolina Agricultural Research Service. NC 50 was developed by a pedigree system of breeding in which initial screening was for field type and total alkaloid level. Greenhouse and field screening were then utilized to identify disease resistance levels and final selections were based on yield and quality trials and further disease testing. NC 50 is a high-yielding, disease-resistant cultivar that has a desirable field appearance and performance, and should be adapted over a considerable portion of the flue cured tobacco growing region.

AN - 14033344; 852004 AB - Mathematical models are needed to better estimate effects of alternative management methods on the amounts of bioavailable P lost in surface runoff over a variety of soil, topographic, and climatic conditions. Methods for estimating concentrations of soil-derived labile (dissolved plus adsorbed) and dissolved P in runoff are proposed and tested. Results indicate that soil analyses in combination with models for predicting the amount and size distribution of eroded soil form a basis for estimating movement of bioavailable P forms in runoff. However, additional studies are needed to determine the range of soil types for which the assumptions inherent in the development of the approach are valid.

AN - 14032720; 861129 AB - The dispersal of C. mohave was studied near the Salton Sea in the lower desert of southern California. Preliminary observations indicated that host-seeking females were most active immediately after sunset and immediately before sunrise. A mark-release-recapture technique was used to document a mean distance traveled of 1.2 km, in 12 hr (the first flight period) and a cumulative distance of 1.94 km after 30 hr (following the second and third flight periods). Nearly 14% of 20,646 marked females were recaptured. Although the mass of the population moved with the prevailing wind, many females dispersed against it, one as far as 6.0 km in 30 hr. Unmarked females were captured at all trapping locations in the Salton Sea basin (up to 4.59 km the larval habitat), but their numbers diminished precipitously 2.5 km beyond the shoreline. JF - MOSQ.

AN - 14028634; 853148 AB - The reservoirs for most bee pathogens are the bees themselves, the hive equipment or hive products (honey and pollen). For example, Bacillus larvae White, the causative agent of American foulbrood (AFB), can be found in honey combs as scales (dried remains of brood killed by disease), package bees, honey and pollen. Katznelson, et al (1952) found high velocity electrons to be effective in killing B. larvae spores in thin sections of comb (3 mm) containing AFB scales (each scale containing ca. 2.5 x 10 super(9) spores) and in a thin layer of honey. But the maximum energy of the electron beam accelerator (EBA) was too low (800 KV) to produce radiation with enough penetrating power to be of practical use. Recent advances in electronics have allowed the design of EBA's which can now develop energies exceeding 3,000 KV (3 million volts), greatly improving penetration. The authors therefore reevaluated electron beams as another potential method of decontaminating bee equipment.

AN - 14027343; 843172 AB - Five white-rot fungi were grown on cellulose fibers and the degradation was observed by scanning and transmission electron microscopy. The white-rot fungi produced hyphal sheaths when grown on cellulose fibers, but sheaths generally were not present between the hyphae and fibers. Autolyzing hyphae and diffusion of cytoplasmic material into sheath or fiber was seldom observed. Therefore, the sheath may not be involved in the degradative process but functions for attachment, nutrition, and protection. The fungi disrupted fiber surfaces. However, degradation was not localized around hyphae but occurred at a distance from them. Thinning of fibers did not occur. Thus, the white-rot fungi must produce a diffusible cellulose-degrading system. JF - Holzforschung AU - Highley, T L AU - Murmanis, L L AU - Palmer, J G AD - For. Prod. Lab., USDA For.

AN - 14024544; 851249 AB - The relationship between temperature and nymphal developmental rate for Wisconsin populations of the pea aphid, Acyrthosiphon pisum , was studied in the laboratory and the field. Population growth statistics varied with rearing temperature but, for apterous cohorts, converged when a physiological time scale ("instar periods") was used. Although stable stage (instar) distributions for the apterous cohorts varied on a physiological time scale, ca. 50% of the individuals in each cohort were first instars, whereas adults accounted for only 7.6 to 13.1% of the total population. Developmental thresholds and population statistics for A. pisum in Wisconsin were similar to an Ontario (Canada) population established in a climate similar to Wisconsin's, but were dissimilar to a British Columbia population established in a warm, arid region. The relevance of these results to the study of A. pisum population dynamics in the field is discussed. JF - Environmental Entomology AU - Hutchison, W D AU - Hogg, D B AD - West. Cotton Res.

Exposure to the combined effects of predators and competitors of the horn fly had a greater effect on horn fly populations than exposure to S. invicta alone. The presence of S. invicta had a negative effect on the native scarabs and on Onthophagus gazella , an imported scarab, as they attempted to colonize fresh cattle manure. However, O. gazella was able to utilize its food source in the presence of large numbers of S. invicta .

AN - 14010003; 833448 AB - A study was conducted to compare shallow groundwater NO sub(3)-N concentrations under intensive multiple cropping systems with those from under nearby nonagricultural sites. The intensive multiple cropping systems involved center pivot irrigation and sprinkler-applied fertilizer. The study was conducted on a sandy Coastal Plain soil by weekly measurement and sampling of observations wells located under a center pivot area and at two forest sites. Nitrate-N concentrations under the center pivot area ranged from < 1 mg/L to about 133 mg/L, with a mean of 20 mg/L. The study raises concern about shallow groundwater quality under intense multiple cropping systems on sandy soils. Although studies in this physiographic area of the Coastal Plain have shown that relatively impermeable subsoil horizons cause shallow groundwater to flow laterally to the larger drainage networks, and that alluvial forests then remove most of the N, the results of this study imply that groundwater NO sub(3)-N contamination could be a problem in other physiographic areas having sandy soils lacking such subsoil horizons.

Females deposit eggs in soil (0.5-5 cm deep) beneath the manure. Embryonic incubations averaged 2.3 days; larval development (three instars) required ca. 12.5 days and pupal development averaged 11.5 days at 27 degree C. Development from egg to adult averaged 26.3 days at 27 degree C. Precopulatory behavior characteristic of that observed for H. coenosus Erichson, H. incertus Marseul, and Saprinus pennsylvanicus Paykull is described. Predation during egg-to-pupa and larva-to-pupa developmental periods resulted in mean horn fly population reductions of 96.0 and 97.9%, respectively; pupal predation resulted in a mean horn fly population reduction of 50.9%.

Substantial diet overlap occurred during winter and early spring on all forested sites, but diets were largely complementary during the remainder of the year despite limited grass production. Diets on clear-cuts were complementary yearlong, with deer selecting primarily leafy browse and forbs and cattle eating mostly grasses and grasslike plants. Findings should aid in developing grazing practices that minimize competition between deer and cattle. JF - Journal of Wildlife Management AU - Thill, R E AD - USDA For. Serv., South. For. Exp.

The Millington and Quirk tortuosity model used in representation of the soil diffusion coefficient was found to give a good prediction of the water content dependence of the effective diffusion co-efficient observed in several studies. The thickness of the stagnant boundary layer predicted from our similarity assumption was shown to be consistent with the apparent thickness inferred from several laboratory and field measurements of volatilization.

Application to the micronucleus test. AN - 13994025; 813969 AB - To facilitate scoring micronuclei in peripheral blood erythrocytes, we have developed a centrifugation method to concentrate polychromatic and newly-formed normochromatic erythrocytes from microliter quantities of blood in a Percoll density gradient. Erythrocytes were separated into two discrete bands in a continuous gradient generated in situ in a microhematocrit capillary tube. The upper band contained white blood cells and a mixture of polychromatic and young normchromatic erythrocytes. Older normochromatic erythrocytes migrated to the lower band. The frequency of polychromatic erythrocytes was increased from approximately 2% in whole blood to 6-80% in the upper band. After clastogen treatments, the elevated frequencies of micronuclei in the upper band polychromatic erythrocytes were similar to those in unfractionated blood.

AN - 13992335; 827525 AB - Several plant-parasitic nematodes are known to reduce pasture and rangeland productivity. Among the endoparasitic nematodes found associated with grasses in the United States. Meloidogyne spp. and Pratylenchus spp. are the most aggressive. Recently, M. chitwoodi Golden et al. was shown to parasitize barnyardgrass, downy bromegrass, lovegrass, meadow fescue, and orchardgrass. However, it is not known if range grasses are also attacked by this parasite. The objectives of this study were to determine the response of seven grass species to M. chitwoodi .

AN - 13990234; 826217 AB - Importance values based on cover and frequency were determined for 36 weed species in understory samples from 47 apple orchards located in Henderson County, North Carolina. Orchard sub-groups identified by cluster analysis of the weed composition data included two major groupings dominated by grasses and woody perennials, respectively. Ordination by detrended correspondence analysiss (DECORANA) was used to extract axes of compositional variation in orchard weed vegetation. All grasses, most perennial forbs and all summer-annual forbs decreased in importance along a first ordination axis based upon data from 43 orchards. Two perennial forbs and all woody perennials increased in importance along the same axis, while species-richness of weeds declined. Results of multiple regression indicated that the annual frequency of paraquat application from 1976 to 1979 was the single factor for the greatest compositional variation in the first two axes of the 43-orchard ordination.

AN - 13989984; 825881 AB - The first of two special issues on urban forest ecology offers new empirical work describing forest structure and composition. Four avenues of inquiry are pursued in this introductory paper with the purpose of setting the contributions of the species issue in context of the existing literature. First, in temperature regions of the world, it is likely 60-80% of a city's area supports enough trees to meet conventional definitions of "forest". Second, the geographical distribution of canopy cover is understood best as dependent upon the historical development of the city and its division into land-use sectors. Third, physiognomy is poorly understood and varies widely depending on the amount and kind of human intervention in the colonization and regeneration processes. Fourth, dominance and diversity are likely to be hotly debated questions of urban forest structure because of lack of agreement as to what constitutes a "good" composition. JF - URBAN ECOL.

AN - 13989765; 826438 AB - Studies with tropical Anthonomus grandis grandis Boheman from southern Mexico indicated that these weevils remained quiescent, did not attain a true diapause state, and remained potentially physiologically active and reproductive during the noncotton season (January-July). The weevils completed their life cycles and remained encapsulated in a "quiescent" or "resting" state inside the dry bolls throughout the dry season (January-March). Over 50% of the dry bolls that were collected in January and February and protected from the rain yielded live reproductive weevils when opened in July. All weevils were found to be active and capable of reproduction a few hours after eclosion from the dry bolls.

AN - 13988920; 823222 AB - The influence of environmental and host factors on the initiation and development of black spot disease on both resistant and susceptible elm clones was investigated. Optimum disease development occurred when plants were exposed to 100% relative humidity at 16 C for 24 hr following inoculation with 10 super(6) spores per milliliter of conidial suspension. Low temperatures (12-16 C) resulted in increased disease incidence in moderately susceptible clones but did not have a significant effect on a highly susceptible clone of Ulmus laevis). Temperature did not influence the type (sporulating vs nonsporulating) of lesion present. Young, growing leaves were most susceptible; no lesions were found on leaves below the third internode from the growing tip. Repeatability estimates were high (0.88-0.91), which suggests a high heritability for clonal response to S. ulmea and a good potential for breeding and selection for resistance.

AN - 13987438; 826141 AB - A key factor to success in mined-land revegetation is the quality of minesoil left on the reshaped surface during reclamation. Where overburden properties are agronomically acceptable, productivity of the reshaped spoil itself may be as great than the pre-mine soil. In other cases, minesoil construction must include selective placement of salvaged topsoil or various subsoil or overburden strata mixtures on the spoil surface. Since the best management practice in this regard is at least regionally specific, several minesoil profile construction options were evaluated for a proposed lignite surface mine in east-central Texas.

AN - 13986565; 819684 AB - Inheritance of resistance of inbred NC250 of maize (Zea mays ) to southern corn leaf blight incited by Helminthosporium maydis race 0 was investigated using seedlings and mature plants. Reactions of seedlings artificially inoculated in greenhouse tests indicated resistance was recessive and ratings of three parents were B73 susceptible, B73rhm resistant, and NC250 segregating. Generation mean and diallel analyses indicated mainly additive effects for reaction to H. maydis race 0. Resistance conditioned by rhm -gene was generally satisfactory to about flowering and then declined in effectiveness; however, rhm -gene influenced mature plant resistance as demonstrated by comparisons between 200 F sub(3) families in each of two populations. These comparisons demonstrated enhancement of mature plant resistance by a gene for resistance in the seedling stage. Segregation ratios for F sub(2) plants and F sub(3) families indicated two recessive complementary loci for resistance while quantitative analyses estimates suggested this interpretation was an over simplification.

AN - 13982412; 819148 AB - Recurrent selection methods have been developed that emphasize the improvement of either one population (intrapopulation improvement) or the cross between two populations (interpopulation improvement). Choice of method to use depends on the objectives of the breeding program relative to the population(s) under selection, traits under selection, and the projected use of the improved population(s). Reciprocal full-sib selection was initiated in BS10 and BS11 maize (Zea mays L.) populations to emphasize selection for specific combining ability. Grain yield was the primary trait under selection, but consideration also was given to maturity and lodging resistance.

AN - 13982185; 819700 AB - Gray mold, caused by Botrytis cinerea is a potentially serious disease of kenaf (Hibiscus cannabinus ) which usually attacks in the fall under cool temperatures and high humidity and can cause loss of an entire stand under epiphytotic conditions. Inheritance of resistance to gray mold was studied in the laboratory in 1-week-old S sub(1), F sub(1), backcross, and F sub(2) progenies tracing to three parents. Data indicate that resistance was conditioned by two genes; the genotype R _ss produced the resistant phenotype and R_S_, rrS _, and rrss the susceptible. It is hypothesized that resistance is conditioned by R and is completely dominant to susceptibility ( tau ); however, S (completely dominant to s) supresses the expression of R.

AN - 13982108; 819178 AB - Two new alleles were sited at the sm sub(1) locus of tetraploid Gossypium hirsutum) L., upland cotton. One allele, derived from the wild Hawaiian tetraploid species, G. tomentosum Nutt. ex Seem., removed all trichomes from stems and most of the trichomes from mature leaves. The allele is dominant to "normally pubescent", the phenotype of most cultivars of upland cotton. The second allele stems from the Peruvian diploid species, G. raimondii Ulbr. The allele greatly enhanced density of tomentum of the upland cultivar "Empire", is dominant to "normally pubescent," and masks the expression of Sm sub(2) (A subgenome glabrousness allele). The finding of an allele at the s)m) sub(1) locus that enhances the density of pubescence, taken along with three other alleles at the locus that remove varying amounts of pubescence from the cotton plant, suggests that the sm)d1locus of the D subgenome is the homoeologue of the sm sub(2), or h) sub(1), locus of the A subgenome which bears an assortment of alleles that produce similar effects.

AN - 13980235; 819397 AB - Although two well-known mycorrhizae-forming fungi, Laccaria laccata and Thelephora terrestris are frequently observed in Lake States nurseries, the association of these and other known mycorrhizal fungi with specific conifer nursery stock has not been formally surveyed. Therefore, a three year survey was initiated in 1980 to identify endemic nursery mycorrhizal fungi. Nine fungi were represented in the survey's 116 collections; Entoloma sp., Hebeloma sp., Inocybe lacera , L. laccata , Pisolithus tinctorius , Rhizopogon rubescens , Suillus luteus , Thelephora terrestris , and Tylopilus felleus . This survey was designed to elicit qualitative, not quantitative nursery mycorrhizae data. The frequencies of the fungal collections for various species do not necessarily indicate the relative importance of these fungi in forming mycorrhize with conifer hosts. There are two reasons for this: 1) the number of fruiting bodies a fungus produces may not be proportional to the number or effectiveness of mycorrhizae it forms with higher plants, and 2) brightly colored, persistent, and/or large fruit bodies are more likely to be collected than those that are drab, nonpersistent, and small.

Results suggest a possible advantage to using MS samples when selecting for increased prolificacy in "Hays Golden" germplasm.

AN - 13978704; 819104 AB - USDA 65009 is a new germplasm line (Humulus lupulus L.) (Reg. no GP 15) resulting from a cross between "Brewer's Gold" (Accession no. 19001) and the male USDA 19058M, an open-pollinated seedling of the old English cultivar Early Green. The compact cone type of USDA 65009 plus the high soft resin and lupulin content make the genotype an ideal parent for hop breeding. In test crosses the compact cone type and high alpha acid content have been readily transmitted to the progeny. By selecting suitable male parent, offspring with good storage stability could also be obtained.

AN - 13975086; 806024 AB - Eight legume species were grown in hydroponic culture in controlled environment (CERES phytotron) facilities to determine if the species exhibited differential nodulation tolerance to nitrate nutrition (0, 1.0, and 4.0 mM initial concentrations, allowed to deplete with plant growth). Visible nodule appearance on roots of lupin (Lupinus angustifolius ), pea (Pisum sativum ), subterranean clover (Trifolium subterraneum ), chickpea (Cicer arietinum ), and siratro (Macroptilium atropurpureum ) was less sensitive to nitrate than that on roots of soybean (Glycine max ), lablab bean (Lablab purpureus ), and barrel medic (Medicago truncatula ). Rates of nitrate depletion from solution and levels of nitrate reductase activity in leaves and roots varied appreciably among species, however no clear relationship was evident that either rate of NO sub(3)u- uptake or site of NO sub(3)u- metabolism was responsible for the differential delays in nodule appearance.

Introduction of the competitive bacterium, Erwinia herbicola M232A (not active in ice nucleation) did not lower the temperature at which freeze injury of tomato shoots occurred. Streptomycin was effective in reducing freeze damage of tomato shoots only when mixed with the Pseudomonas syringae suspension prior to plant inoculation. Spectinomycin, another aminoglycoside, was effective in reducing frost damage to tomato plants due to P. syringae . Bacteria present intercellularly (within the plant) may play a significant role in bacterial ice nucleation.

Overview. AN - 13963849; 798241 AB - The Environmental Protection Agency initiated the National Crop Loss Assessment Network (NCLAN) to develop pollutant dose-plant response information for economically important crop species. The primary thrust of the NCLAN program is to assess the effects of O sub(3) on crop yield. This paper is part of the third assessment report from NCLAN, which is composed of several cooperating programs with field sites in different regions of the country. Plants are grown in the field using open-top chambers for the countrol and manipulation of gas concentration around the crop plants. Four to six O sub(3) treatments are used in each experimental design and O sub(3) is added for 7 h/day in constant or proportional amounts to ambient air O sub(3) concentrations. The most extensive ambient O sub(3) monitoring data in the U.S. are provided by the Storage and Retrieval of Aerometic Data (SAROAD) system. By the use of an interpolative process called Kriging, county level O sub(3) concentrations can be estimated. Ozone concentrations are monitored in the NCLAN treatment chambers using shared-time monitoring. Data are summarized and presented as a seasonal mean of the daily 7-h mean O sub(3) concentrations for each treatment. The NCLAN air quality data are compatible with the SAROAD system. JF - J.

Treatments imposed beginning 85 days after planting were drought, drought with heated soil and 3 drought treatments with cooled soil. The incidence of A. flavus in drought-stressed, unshelled, sound mature kernels (SMK) decreased with decreases in the mean 5 cm deep soil temperature. The incidence of A. flavus was greater in inedible categories and in damaged kernels than in SMK. The mean, threshold, geocarposphere temperature required for aflatoxin development during the latter part of the peanut growth cycle was found to be between 25.7 degree C and 27 degree C.

Zea mays var. huehuetenangensis (Huehuetenango teosinte) is isoenzymatically distinct from both sections, but shows its closest relationship to Z. mays var. parviglumis of sect. Zea . Mexican annual teosinte is the ancestor of maize. Zea tends to show greater within population heteroxygosity and more variance within species and subspecies than most other plants that have been studied isoenzymatically. JF - Systematic botany.

AN - 13950731; 793387 AB - Groups of 30 rats each were fed 1 of 4 diets to determine feeding preference for freeze-dried meal compared to dry meal, and to determine if 3% agar is a desirable component of freeze-dried meal. Diet preparation, and the method for introducing a toxin in a toxicological study, is described. There were no significant variations in feed conversion ratios among the dietary treatment groups. Freeze-dried diets have a longer storage and cage life, thus the frequency of diet preparation, animal feeding and clean-up are reduced. For studies involving a toxin, these factors would reduce the potential for accidental exposure of personnel to potentially harmful materials.

Seven regression models were tested by these data of each instar, and two consistently best met the established criteria for predicting net and total dispersal: Y = b(1+a) super(2)/(X+a) super(2) and Y=exp super((a+bX1/2)) where "X" was the distance class and "Y" was the proportion of the population for that class. These two models strongly suggest that net and total dispersal patterns were very similar, movement was not random but directional, and most larvae were stationary during the day with only a few individuals traveling relatively long distances.

AN - 13946886; 786221 AB - Branch growth and leaf formation from terminal and from lateral buds of red maple (A. rubrum ) and red oak (Q. rubra ) were measured in response to simulated insect defoliation. A single large branch representative of the crown of each tree was used for enumeration of growth and of bud numbers throughout three successive years of 0, 50, 75, and 100% leaf removal for the entire tree. Leaf number per tree for both species after the last year of defoliation was reduced in direct proportion to the severity of defoliation. Bud number per tree for red maple, was also reduced in proportion to severity of defoliation. In contrast to red maple, undefoliated red oak incurred a substantial amount of branch death throughout the study which was little affected by defoliation treatment.

I. Storage effects. AN - 13933696; 773215 AB - A mixture containing equal numbers of seed of eight snap bean (Phaseolus vulgaris L.) cultivars was prepared to determine the effects of seed aging on genetic shifts in the population. The mixture was artificially aged to simulate long-term storage using elevated storage temperatures and relative humidities/seed moisture contents. After seed aging, germination of each cultivar was regressed on the germination of the mixture to develop a series of equations which could be used to predict relative germination of the eight cultivars at any given level of germination for the mixture. The results of this experiment demonstrate the potential for loss in genetic variability within heterogeneous germplasm accessions during long term storage.

Procedures are also developed for analyzing the uniformity of fire spread, given four time observations. Flexible sampling techniques allow the procecures to be adapted to a wide variety of fire-related phenomena on prescribed fires or wildfires. Using the procedure, we stratified rate of spread data for a prescribed fire into two significantly different groups.

AN - 13928864; 777795 AB - Ovipositional nonpreference of the sorghum shoot fly, Atherigona soccata (Rondani), for seven selected cultivars of sorghum, Sorghum bicolor(L.) Moench, was compared with that for a susceptible hybrid, CSH-1, in a screen house. In a single-choice test, females exhibited a highly significant nonpreference for oviposition on IS 2416, IS 3962, and IS 5613. Females that had no choice for an oviposition substrate, but could escape into an outer cage, showed significant nonpreference for five test cultivars. There was no correlation between nonpreference for a cultivar and the number of females that escaped into the outer cage. Behavioral observations indicated that first landing by a female was random but her stay on IS 2146, IS 3962, and IS 5613 was very brief. Females laid eggs on nonpreferred cultivars only after laying several eggs on alternate CSH-1 plants.

AN - 13926825; 778538 AB - Open-pollinated seedlings from resistant, moderately resistant, and susceptible slash pines (Pinus elliottii var. elliottii Engelm.) were inoculated with basidiospores of Cronartium quercuum f. sp. fusiforme from two geographic sources at three densities. Variation among pine families, inoculum densities, and sources was assessed in terms of presence or absence of initial symptoms (purple spots on stems and needles), seedlings galled 6 and 9 mo after inoculation, gall lengths, and seedling recovery. Recovery was indicated either by lack of gall formation or small galls that ceased to grow. More seedlings of the resistant and moderately resistant parents than of the susceptible parent developed initial symptoms without subsequently forming galls ("early recoveries"). Frequency of early recovery varied with inoculum density. Fewer seedlings from the resistant parent were galled 9 mo after inoculation, but the distinction between families diminished with increasing density.

Isolations were made from root and stem tissue of 800 weed plants collected throughout the growing season from conventional tillage and no-tillage soybean fields at 20 locations. Fusarium oxysporum was obtained from 16 weed species. No direct relationship to tillage practice was noted. Sixteen of 17 isolates of F. oxysporum from weeds were pathogenic on the soybean cultivar Essex under greenhouse conditions. No symptoms of F. oxysporum infection were observed in weed plants collected from the field or when inoculated in the greenhouse with a soybean isolate.

As part of that study, isolations of fungi were made from decaying logs that had been stored for 17 or 48 wk. While a number of the fungi were identified, the majority were not. The present study was undertaken to attempt to complete identification of the unknown isolates because more wood products-associated Basidiomycetes are now identifiable in culture. Knowledge of the fungi frequently associated with deterioration of wood in different products is of value in that it can be used to choose test fungi for inclusion in decay control investigations.

Twelve cultivars gave immune, necrotic local lesion, or tolerant reactions ot CYVV. Individual plants of these 12 cultivars were inoculated with CYVV by an aphid vector (Myzus persicae ) or by a hypodermic method. In seven of the 12 cultivars, receptivity varied from 12.5 to 100%, depending on the method of inoculation. The bean cultivar Navajo showed minimum whereas Rufus showed maximum receptivity to mechanical and aphid inoculations, respectively. The largest difference in percentage of infection occurred in Ouray and GN 1140 for mechanical, aphid, and hypodermic inoculations, respectively. Cultivars Agate, Scout, Gala, Gloria, and GN UI 31 were immune to CYVV regardless of inoculation method. P. vulgaris cv. Monroe was identified as an effective local lesion host for CYVV.

Lesion numbers increased through early summer as a result of secondary leaf infection by conidia. Disease development was maximal in late July and early August, when most defoliation of previously infected leaflets occurred. Leaf wetness periods of 12 Hr or more, suitable for leaf infection, occurred with enough consistency each summer to perpetuate yearly anthracnose epidemics in similar fashions.

I. Influence of Particle size. AN - 13922678; 774674 AB - Diffuse reflectance does not vary linearly with absorber concentration. Therefore, if linear correlation techniques are used for near-infrared reflectance spectroscopy, mathematical treatments of the reflectance data are required. Data treatments found to give a linear correlation with protein content of wheat include log 1/R,dR/ sub(R), Delta (log 1/R),d(log 1/R),D super(2)(log 1/R), and (1-R) super(2)/2R. These data treatments were evaluated for performance in predicting protein content for wheat samples ground with different grinders to give a wide range of particle sizes. The spectral data were also normalized by dividing the same data treatment at a reference wavelength. Particle size had a marked effect on the near-infrared spectra, and this effect carried through to produce large errors in protein prediction without normalization of spectral data. Normalization of data effectively removed the particle-size effect such that second derivative divided by second derivative at optimum wavelengths gave an average bias error of-0.02% with a standard deviation of bias of 0.12% protein for six sample lots with mean particle size varying from 161 to 327 mu m. Normalized second-derivative treatment of data gave the best performance in predicting protein content of samples varying widely in particle size.

M. mucedo grew on green and red tomatoes and PDA at temperatures from 5 to 30 C, with optimal growth at 25 C. M. piriformis grew on the avove substrates at temperatures from 0 to 25 C, with an optimal growth temperature of 20 C. Both fungi grew faster on red than on green fruit; M. mucedo was a more aggressive pathogen than M. piriformis and was capable of completely decaying tomatoes within 2-3 days of inoculation. Of several fungicides tested, only guazatine showed measurable fungicidal action against the two fungi; it significantly reduced decay on ripe red fruit.

Bear Creek (83 km long), a tributary of the Yazoo River in the Mississippi River alluvial delta, is actually a series of six riverine lakes connected by a sluggishly flowing stream. The watershed also includes several other oxbow lakes connected to the stream only during periods of high discharge. Water quality as characterized by total and suspended sediments, deposited sediments, pH, and coliforms deteriorated in a downstream direction. Four species of the sessile colonial invertebrate were indigenous to the three lakes in the system having the lowest total solids, sedimentation rates, and pH.

AN - 13915505; 760686 AB - Clostridium botulinum B-aphis spores plated on medium containing 4% salt at pH 6.0 yielded colonies at a frequency of ca. 1 in 10 super(6). A subculture of one of these colonies, designated strain Ba 410, was compared with the parent strain, B-aphis, for a variety of traits. After 7 days of incubation at 37 degree C, strain Ba410 grew in medium containing 7% NaCl, whereas strain B-aphis could not grow in salt concentrations greater than 5%. The strains also differed in cellular and colonial morphology. After exponential growth in the basal medium was completed, lysis of both strains was pH dependent; in media containing salt, lysis of Ba410 cells was pH independent. Strain Ba410 was more proteolytic than strain B-aphis in conditions of low pH and high salt, so that its toxin could be detected by the mouse assay. In a medium containing alanine and cysteine, the germination rate of B-aphis was 0.77% min1), whereas that of Ba410 was 0.14% min super(-1); 2% salt inhibited the germination of Ba410 but not B-aphis.

Acheplasma species have also been found to differ from Mycoplasma species in possessing a nicotinamide adenine dinucleotide-dependent lactate dehydrogenase that is specifically activated by fructose 1,6-diphosphate and in containing superoxide dismutase, as well as glucose-6-phosphate and 6-phosphogluconate dehydrogenases. In addition, reduced nicotinamide adenine dinucleotide oxidase activity is located in the cell membranes of Acholeplasma species and is associated with the soluble cytoplasmic fraction of Mycoplasma and Spiroplasma species.

AN - 13909393; 756695 AB - Aqueous suspensions of formulated Bacillus thuringiensis (H-14) wettable powder (Bactimos) WP) and B. sphaericus (1593) acetone precipitated spore powder were compared with slow release floating pellet formulations of each pathogen for the control of Culex quinquefasciatus breeding in urban settings. In 15 and 8 liter buckets both suspensions provided complete control at 1 mg of powder/liter but suppression was brief with the B. thuringiensis (H-14) WP. Bactimos) primary powder formulated into small, floating pellets (0.17 g primary powder/pellet), provided limited control for several weeks and was markedly inferior to the Bactimos briquette. One half briquette gave complete control for 3 weeks but its effectiveness declined as the briquette constituents sank. All B. sphaericus treatments provided continuous good to excellent control for the 8 weeks of observation. The best control in the 15 liter buckets was effected with 2 floating pellets each containing 0.21 g of B. sphaericus spore powder. JF - MOSQ. NEWS.

AN - 13909085; 757771 AB - Several cultivar-strain combinations of the Phaseolus vulgaris L. -Rhizobium phaseoli association were evaluated for N sub(2) fixation, N assimilation, and primary (biomass) production. The relative efficiency of N sub(2) fixation was less than 0.60 indicating a loss of reducing power to H sub(2) evolution. Copious production of H sub(2) by all effective strains used in this study suggests that energy losses through H sub(2) evolution may limit the productivity of the Phaseolus-Rhizobium) symbiosis. Assimilation of N by the symbiotic association in response to N sub(2) fixation was influenced by both strain and cultivar effects.

AN - 13908477; 761265 AB - The Wye River, a tributary of Chesapeake Bay, is a shallow, well-mixed estuary surrounded by an agricultural watershed, a large portion of which is planted in corn (Zea mays ). A 3-yr study of the movement of atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) and simazine (2-chloro-4,6-bis(ethylamino)-s-triazine) showed that the total amount of herbicide reaching the estuary depended upon the quantity applied in the watershed and the timing of runoff with respect to application dates. In a year in which significant runoff occurred within 2 weeks of application, 2 to 3% of the atrazine moved to the estuary. In other years with less runoff, or runoff delayed longer after application, much smaller quantities reached the estuary. Simazine loading was one-tenth that of atrazine. Once in the estuary, atrazine and simazine remained in solution, diluted in a conservative manner with estuarine water, and dissipated with a 10- to 30-d half-life. The maximum measured concentration of atrazine was near 15 mu g L super(-1) but average concentration at peak loading was <3 mu g L super(-1).

Carbon dioxide was essential for glucose metabolism. Treponema bryantii catabolized glucose to pyruvate via the Embden-Meyerhof-Parnas pathway. The spirochete used a coliform pyruvate-formate lyase to degrade pyruvate and produce formate and acetate. Succinate was formed by a pathway which involved the condensation of CO sub(2) with pyruvate (or phospho(enol)pyruvate) formed from the breakdown of glucose.

AN - 13907594; 755736 AB - The three-dimensional structure of phosphoglycerate mutase has been analyzed using a contoured distance matrix and by visual inspection using three-dimensional computer graphics. Three folding lobes have been identified and their internal structure tentatively characterized. The active site is located at a lobe interface with a channel providing possible access from above and below. The arrangement of active site residues on two lobes suggests that the active site might be conformationally flexible. The remaining interface not associated with the active site channel appears to be predominately hydrophobic and thus may contribute to inter-lobe stability.

AN - 13907565; 757321 AB - An effort was made to relate the aflatoxin content of individual almond kernels to their fluorescent color. The fluorescence of individual blanched almonds and defective almonds, most of which lack an intact pellicle, was described by means of Methuen color charts before each kernel was analyzed for aflatoxin. Almonds that fluoresced violet-purple under long-wave UV light were found to contain high levels of aflatoxins B sub(1) and B sub(2) but, with perhaps one exception, no measurable amounts of aflatoxins G sub(1) and G sub(2). Some diced almonds with blue fluorescence had all four aflatoxins present but at much lower levels than in the violet-purple kernels. Aflatoxin ranged from 1.0 x 10 super(5) to 2.5 x 10 super(6) ppb in the violet-purple kernels. These values agree with previous estimates of aflatoxin concentration per contaminated nut. Almond kernels with violet-purple fluorescence should be culled. JF - Journal of Food Science AU - Schade, JE AU - King, AD Jr AD - USDA-ARS, Eng. and Food Sci. Res. Unit, Western Reg. Res.

Both large and small scale fermentation is possible using a variety of raw materials or synthetic media. Amino acids are the preferred nitrogen source and the bacterium requires the vitamins biotin and thiamine for growth and Ca super(++) and Mn super(++) for sporulation. It is highly aerobic and grows well between 25 degree and 4- degree C with a neutral pH, but sporulation and toxin production may be inhibited above 35 degree C. Formulation of B. sphaericus will enable easier storage, mixing and application as well as improve stability, efficacy and residual activity. In addition to wettable powders, optimal utilization of this bacterium will require the development of liquid, granular and sustained release formulations. JF - MOSQ. NEWS.

Therefore, cicer milkvetch was evaluated in a 10-parent diallel cross for flowering scrore (profuseness of flowering) in the seedling year and for flowering date in the seedling year and in two growth periods of the 2nd year. The F sub(1) progenies and their reciprocals were grown under irrigation. Significant differences occurred among crosses for all traits. The variance for these traits was partitioned into general combining ability, specific combining ability, and reciprocal effects. Each of these components was significant for all traits.

AN - 13904051; 747208 AB - The activity and survival of O. phyllobia fourth-stage juveniles (J4) were examined in aqueous solutions representing 96 combinations of eight predominant soil solution ions at total concentrations of 100, 200, and 1,000 meq/liter. Various water potentials were imposed by the addition of mannitol or polyethylene glycol to ionic solutions. Nematode longevity increased as water potential was decreased. Longevity was approximately doubled at a water potential of -23 x 10 super(5) Pa and more than tripled at -60 x 10 super(5) Pa. No combination of ions at 200 meq/liter was lethal after a 6-day exposure. Several ion combinations significantly increased longevity at - 10 and -23 x 10 super(5) Pa. Single cation Na super(+) solutions consistently inhibited activity and more than doubled nematode longevity.

AN - 13903505; 747799 AB - Measurements obtained between 1968 and 1976 indicate the influence of climatic factors and soil characteritics upon soil moisture and production of perennial vegetation in the northern Mojave Desert. Seasonal distribution patterns of precipitation are shown to have a strong effect on plant-available soil moisture, and these patterns are, in turn, reflected in net production of perennial vegetation. Available climatic data and soil characteristics were used as input to a continuous simulation model to calculate the water balance for a unit area watershed. Computed and measured soil moisture agreed quite well over a range of values from close to the wilting point to near field capacity. The authors used computed evapotranspiration rates to estimate water use by perennial vegetation. Computed water use was multiplied by a water use efficiency factor to estimate net production of perennial vegetation. Estimated net production exhibited year-to-year variability comparabe with measured values, and agreed quite closely with available observations. This paper briefly describes soil-water-plant relationships in the northern Mojave Desert and illustrates an application of a continuous simulation model to predict soil moisture and net production of perennial vegetation.

AN - 13902806; 757104 AB - Axillary shoot proliferation from cranberry (vaccinium macrocarpon Ait.) nodes in vitro was correlated positively with glyphosate ((N-(phosphonomethyl)glycine, (Gly)) and isopentenyladenine (2iP) concentrations. Maximum proliferation was caused by 3.7 x 10 super(-3) M Gly or 1.5 x 10 super(-4) M 2iP. Shoot proliferation was reduced when combined at levels above 1.9 x 10 super(-3) M Gly and 7.4 x 10 super(-5) M 2iP, Gly and 2iP reduced shoot and root dry weight. Indoleacetic acid (IAA) did not significantly affect shoot proliferation or shoot and root growth at concentrations of 5.7 x 10 super(-6) M and 5.7 x 10 super(-5) M. Gly induced basal swelling of shoots and reduced leaf size. These characteristic Gly effects were not altered by 2iP or IAA, Gly may be a useful addendum for in vitro shoot proliferation and a tool for the investigation of meristem initiation and development.

AN - 13898835; 747816 AB - A greenhouse study was conducted to determine seedling survival probabilities of sideoats grama (Bouteloua curtipendula (Mich x.) Torr.) and cochise lovegrass (Eragrostis lehmanniana Nees x Eragrostis trichophora Coss & Dur.) for selected combinations of initial wet-day and dry-day sequences. Three separate 14-day experiments were conducted using 1, 2, 3, 4, and 5 days wet followed with 5 days dry. The number of emerging seedlings growing from 10 seeds placed in a sand media in small plastic cones were counted daily. A total of 50 to 70% of the sideoats grama seeds emerged in the initial wet period, but over 50% of the seedlings died in the following 5-day dry period, resulting in less than a 35% survival rate. The cochise lovegrass was slower to germinate and less susceptible to the effect of the 5-day dry period, which resulted in 40 to 60% seedling survival. With the 1- and 2-day wet sequences, the maximum cochise lovergrass plant count was not achieved until the final rewet period. With the exception of 5 days wet, the length of the initial wet period did not significantly affect the number of surviving lovegrass seedlings.

This protocol differs primarily from the International Standard Protocol adopted by the WHO in that: (1) A standard cup for exposure of larvae is specified; (2) 20 larvae per cup and 3 cups per concentration are required; (3) a minimum of six concentrations must comprise a replication; (4) computer-assisted analysis by parallel potency probit analysis is required; and (5) pupation or mortality in excess of 5% in the untreated control invalidates that assay replication. Each replicate must have a CV of 0.2 or less, in addition to other specified responses. A set of four B. thuringiensis (H-14) preparations was tested, using this protocol to provide an example of the accuracy to be expected. Specific recommendations are made about the handling of reference standards and the establishment of new standards in the future when current supplies are depleted. JF - BULL. ENTOMOL. SOC. AM.

AN - 13893556; 739563 AB - A triploid hybrid (2n = 3x = 36) between a colchicine-induced 4x(2EBN) Solanum brevidens (a non-tuber-bearing species) and 2x(2EBN) S. chacoense (a tuber-bearing species) was used as a vehicle for germplasm transfer to S. tuberosum Group Tuberosum. The use of 2n gametes from the triploid allowed the unique opportunity for transferring exotic germplasm from Series Etuberosa to Gp. Tuberosum material. Results suggest that the tuberization response is a dosage and/or threshold effect. This approach to the incorporation of IEBN germplasm indicates the utility of the EBN concept coupled with 2n gametes. Further, it demonstrates a means for the introgression of IEBN species genes into Gp. Tuberosum material. JF - Theoretical and Applied Genetics AU - Ehlenfeldt, M K AU - Hanneman, RE Jr AD - Dep.

AN - 13893464; 740211 AB - A carlavirus isolated from Kalanchoee blossfeldiana "Texas Sunset" and designated KV-2 was compared with a previously characterized carlavirus isolated from cultivar Rotkappchen and designated KV-1. The isolates had similar host ranges, thermal inactivations ( similar to 75 C), buoyant densities (1.30 g/cc) and capsid protein molecular masses (33,000-34,000 daltons). KV-2 was distinguished from KV-1 in that KV-2: systemically infected Chenopodium spp. that were only locally infected by KV-1; had a normal length that was about 30 nm longer than that of KV-1; and was degraded by reagents such as 1% Triton X-100, 5 mM EDTA, and chloroform-carbon tetrachloride that did not degrade KV-1. KV-2 was purified from C. quinoa by clarification of phosphate-buffered crude sap extracts with 1,1,2-trichloro-1,2-2-trifluoroethane (Freon), precipitation with 6% polyethylene glycol, and centrifugation on 10-14% linear CsCl density gradients. SDS-degraded KV-1 and KV-2 formed lines of partial fusion in Ouchterlony gel double diffusion tests. Isolate-specfic antibodies were found in each homologous antiserum in intragel cross-absorption tests. Both isolates reacted in indirect ELISA with antisera to carnation latent, chrysanthemum B, lily symptomless, and potato S viruses, but not to elderberry A, hippeastrum latent, red clover vein mosaic. or narcissus latent viruses. Since only minor differences were found in most of the properties of the two viruses, KV-1 and KV-2 are concluded to be strains of the same carlavirus, here designated kalanchoee latent virus.

AN - 13889019; 736328 AB - A lithium acetate-dimethyl sulfoxide ninhydrin reagent was shown to be useful for reaction of amino groups in a series of structurally diverse food proteins and flours of variable lysine content. The proteins were bovine serum albumin, casein, hemoglobin, lactalbumin, lysozyme, soybean protein, soybean trypsin inhibitor, trypsin, and wheat gluten. The flours were barley, high lysine corn, high protein rice, lima bean, nonfat dry milk, rice, soy, and wheat. The ninhydrin-reactive lysine content of these proteins varied from 63-109% of the theoretical values. This variation needs to be taken into account in possible applications of the ninhydrin reaction to food proteins.

AN - 13883711; 738405 AB - Engorged larval, nymphal, and female lone star ticks, A. americanum , were released at monthly intervals in different habitats in southeastern Oklahoma during April-October in 1978-1980 to study their development and survival. Bottomland oak-hickory, upland oak-hickory, and upland pine habitats were nearly equally suitable areas for tick survival during 1978-1979 when rainfall and temperature were similar. High temperatures and low humidities in 1980 reduced tick survival in all habitats by at least 50% from that observed in 1978 and 1979. However, the bottomland oak-hickory habitat had significantly higher survival of ticks than the 2 upland wooded sites during the summer drought of 1980 and was the only habitat in which ticks molting in 1979 survived the summer of 1980. The 4th habitat, a meadow, was much less suitable for tick survival and development during all 3 consecutive years.

AN - 13883318; 740467 AB - Eggs and each instar of the cabbage looper, Trichoplusia ni , were introduced weekly into Missouri soybeans to assess natural mortality. Percent recovery 24 h later demonstrated high mortality due to predation, which peaked between flowering and pod fill of the soybeans. First and 2nd instars were most susceptible, with seasonal average mortalities of 51.9 and 43.5%, respectively; 3rd and 4th instars were least susceptible, with averages of 30.1 and 25.0%, whereas mortality of 5th instars, 34.9%, was intermediate. Few of the recovered eggs or larvae were parasitized, but disease caused significant mortality of larvae, due especially to a late-season epizootic of the entomopathogenic fungus, Nomuraea rileyi (Farlow) Samson. Parasitism, mostly by Rogas nolophanae and Cotesia marginiventris peaked at 36.3% in July. Mortality due to disease reached a peak of 70.0% late in the season, again due to the epizootic of N. rileyi .

AN - 13882350; 737896 AB - The feasibility of using the sterile-insect technique (SIT) to control the stable fly, Stomoxys calcitrans (L.) was demonstrated in small-scale field tests in Florida, USA, and in a large integrated pest management program on St. Croix, U.S. Virgin Islands. Since a genetic sexing strain (GSS) of S. calcitrans has been developed for incoporation in a SIT program for population suppression, the mating competitiveness of males of this strain was evaluated after sterilization by gamma radiation. The GSS males were subjected to dieldrin as larvae and irradiated as adults for competitiveness tests against males that were not exposed to dieldrin or radiation. The irradiated GSS males were about equally competitive with untreated males in these tests. Tests with a mutant marker strain showed that females mate only once.

AN - 13881846; 738091 AB - Small kraft paper bags containing 100 g of cornmeal were exposed as open bags or closed bags with folded or heat-sealed (taped) openings in 44.7-m super(3) rooms. There were significantly fewer of the folded bags and taped bags infested by the almond moth, Cadra cautella), when 50 pairs of adults of Bracon hebetor were introduced into the test rooms five times at semiweekly intervals. The numbers of moth larvae recovered from the infested bags also were significantly reduced in folded and open bags when the parasites were present. The benefits of making the bags insect tight were obvious in the Bracon -free control room, because significantly fewer taped bags were infested than folded bags and significantly fewer folded bags were infested than open bags. The numbers of moth larvae recovered from the infested, folded bags and taped bags were also significantly lower than the number of moth larvae found in the open bags.

AN - 13881625; 734087 AB - Broiler chicks were vaccinated subcutaneously in the neck at various ages with a single 0.5-ml dose of beta-propiolactone-inactivated Mycoplasma gallisepticum (MG) oil-emulsion bacterin. Broiler chicks vaccinated at 1 day of age had only slight protection against the development of air sacculitis. When broiler chicks were vaccinated with MG bacterins at 11 to 15 days of age, they acquired significant protection against air sacculitis compared with controls. Viable MG organisms were readily isolated from most of the sampled tracheas and air-sac lesions cultured 21 days post-challenge, indicating a lack of protection against infection of the respiratory tract. MG-vaccinated chicks generally produced antibodies readily detectable by the rapid serum-plate test, tube-agglutination, and hemagglutination-inhibition (HI) tests. Low HI titers at challenge were not necessarily indicative of lack of protection against the development of air sacculitis, since good protection was often observed in chickens with low to moderate HI titers.

AN - 13880018; 737007 AB - Male Fisher 344 rats were fed diets containing either 20% corn oil, 20% coconut oil or 18% coconut oil plus 2% corn oil for 3 wk. A single dose of ( super(3)H)aflatoxin B sub(1) (( super(3)H)AFB sub(1)) was administered ip and the biliary excretion of aflatoxin metabolites and the binding of super(3)H to nucleic acids were studied. In other experiments the in vitro metabolism of AFB sub(1) by liver postmitochondrial supernatants prepared from rats fed the different sources of dietary fat was determined. The results of the in vivo and in vitro studies suggest that the formation of the putative carcinogenic metabolite, AFB sub(1)-epoxide, which undergoes detoxification through glutathione conjugation, is not affected by the type of dietary fat. The observations further suggest that dietary fat, in particular unsaturated fat, affects AFB sub(1) carcinogenesis through a mechanism other than by alteration of the metabolic activition of AFB sub(1).

AN - 13878862; 736415 AB - A nodule cytosol nitrite reductase was isolated from soybean (Glycine max (L.) Mer. cv. Tracy) grown in the presence of nitrase. Enzyme activity increased when increased amounts of nitrate were supplied to the plant. A purification procedure involving ammonium sulfate precipitation, gel filtration, DEAE Sephadex and Blue Sepharose chromatography resulted in an activity capable of forming 6.7 mu mol ammonia (mg protein) super(-1) min super(-1). This represented a 235-fold increase in specific activity. The molecular weight, estimated gel filtration, was 55,000. The pH optimum for activity was 7.1. Ammonia formed stoichiometrically as nitrite was consumed. From Lineweaver-Burk plots, K sub(m) values of 0.5 mM for nitrite and 0.2 mM for methyl viologen were calculated. Spectral data suggest the association of a heme chromophore with the enzyme. JF - Physiologia Plantarum AU - Hunter, W J AD - USDA-ARS, Soil-Plant Nitrogen Res. Unit, P.O.

AN - 13874866; 725473 AB - Manganese was identified as a factor in spices responsible for the enhancement of acid production by meat starter bacteria. Stimulatory activity of 0.1N HCl extracts of spices increased with increasing Mn concentration. Extracts of clove, cardamom, ginger, celery seed, cinnamon, and turmeric, all with high Mn contents, were strongly stimulatory. Clove had the highest Mn content and exerted the greatest stimulatory effect. Spice extracts or standard Mn super(++) solutions enhanced acid production by Lactobacillus plantarum more than by Pediococcus acidilactici in a beef extract-sugar medium. Fermented sausages without spices but with added 1 x 10 super(-5)M Mn super(++) and those with spices developed a similar level of acidity.

AN - 13873557; 719279 AB - An electrophoretic comparison of 13 emzyme systems, consisting of the isozymes coded at 17 loci, was made between laboratory colonies of Toxorhynchites rutilus, Tx. theobaldi, Tx. amboinensis, and Tx. brevipalpis and 4 natural populations representing both subspecies of Tx. rutilus that occur in the United States. Identity values obtained from comparisons of the natural populations of Tx. rutilus were large, suggesting that the morphological differences by which these subspecies are defined arose with little differentiation of enzyme polymorphisms. Comparisons of the laboratory colonies of the different species both to one another and to the natural populations of Tx. rutilus yielded very small identity values. Most of the colonies had heterozygosity and polymorphism values in the range observed in wild populations of Tx. rutilus and other well-studied species of mosquitoes. These observations are discussed in relation to the choice of one of the colonized species for release to control vector mosquito species in the United States.

AN - 13873107; 729679 AB - When 118 virulent (V) and 27 hypovirulent (H) isolates of Cryphonectria parasitica were paired in culture, 95% of the V isolates were converted to the hypovirulent condition by at least one of the H isolates. The 118 V isolates in 54 vegetative compatibility (v-c) groups included representatives from West Virginia, North Carolina, Virginia, Tennessee, and Italy. The average conversion capacity of the 27 H isolates was 15% and ranged from 0 to 41%. Eight cluster analyses based on different similarity functions were performed to group V isolates according to their susceptibility to conversion. The most useful cluster analysis was based on the square root of the number of sectors converted by individual H isolates and formed nine conversion groups and left only eight isolates ungrouped. Twenty-eight of the 54 v-c groups had more than one V isolate, and isolates in 15 of these v-c groups were also together in conversion groups. Clustering appears useful for determining relatedness among v-c groups. Conidial or mycelial slurries of 7, 15, and 27 H isolates converted 87-93% of 102 randomly selected V isolates from North Carolina. All 102 V isolates were converted by at least one of the H isolate treatments. Conidia were as effective as mycelia in conversion, but more of the colony margin of the V isolates had altered growth from mycelial slurries than from conidial treatments.

AN - 13872150; 729467 AB - Differences in stream chemistry between recently clearcut and near-by uncut watersheds were generally small in a wide variety of soil and forest types throughout New England. Water samples were collected during six periods of the year in 1978 and 1979 from 6 entirely clearcut, 32 partially clearcut, and 18 uncut watersheds. The largest differences that could be attributed to harvesting occurred in entirely clearcut watersheds, expecially in the White Mountains of New Hampshire. In one area of the White Mountains, inorganic N was 4 times higher (2 mg/L), and Ca was 2 times higher (4 mg/L) in streams from a clearcut watershed than in a nearby uncut watershed. Elsewhere, only minor changes in stream chemistry resulted from cutting; the amount of the cutting response was of the same magnitude as natural variations among streams draining similar watersheds. Clearcutting less than entire watersheds, patch and strip cuts, and buffer strips along streams all appear to reduce the magnitude of changes in stream chemistry.

AN - 13871235; 724995 AB - In Woolley's medium 17 isolates of tabtoxin-producing pathovars of Pseudomonas syringae produced taxtoxin. However, when the medium was supplemented with intercellular fluid from tobacco leaves, 14 of the isolates now produced tabtoxinine- beta -lactam rather than tabtoxin. At the time chlorosis first became evident in leaves infected by these isolates, only tabtoxinine- beta -lactam could be detected in the intercellular fluids, and no peptidase activity towards tabtoxin was detectable. Intercellular fluids from leaves infected by the three unusual isolates contained only tabtoxin. These results show that, depending upon the isolate, the intercellular environment can control which molecular form of the toxin is produced. JF - PHYSIOL. PLANT PATHOL.

AN - 13870679; 716962 AB - Foliar symptoms of brown spot (caused by Bipolaris oryzae ) were modified in field plots by the presence of a rice line that promotes spreading of the disease and by the use of fungicides. There was no correlation between brown spot symptoms and floral abortion, and kernel discoloration was moderately correlated with brown spot. In this study, panicle blight, a disease of unknown etiology, was the primary cause of floral abortion and rice stink bug feeding was the major factor in kernel discoloration. It was concluded that B. oryzae was a secondary invader of aborted florets, that it was possibly the primary cause of some kernel discoloration, and that it was just one of many microbes that colonized kernels through stink bug feeding wounds.

AN - 13870519; 717024 AB - A survey for pitch canker among ramets of eight clones in a seed orchard of Virginia pine (Pinus virginiana ) in Alabama indicated that the incidence of disease (0-52% ramets with cankers) was related to specific clones. When seedlings of half-sib families from these clones were inoculated with Fusarium moniliforme var. subglutinans , the causal agent of pine pitch canker, the ranking correlation of the families for susceptibility to the pathogen (based on 2 yr of trials) to the seed orchard survey averaged 0.77. In the field, dead shoots became defoliated. Prior to needle drop, hyphae were observed on the surfaces of the needles, and microscopic sporodochia were observed emerging from the epidermis adjacent to the needle fascicles. Histological examination of surviving shoots from inoculated seedlings and branches indicated that the formation of a periderm in the cortex and reaction parenchyma in the xylem was a factor in delaying invasion by the pathogen.

First-instar larvae were generally stationary; instars II to IV traveled an average of 1 to 3 m each, instar V averaged 9 m, and instar VI averaged 20 m. Maximum larval movement occurred just before pupation. Maximum total movement for the entire larval period was less than 100 m, demonstrating that larval dispersal is not the major cause of range expansion. Direction of movement of all the instars was highly variable, and no distinct pattern was ascertained.

AN - 13869996; 729625 AB - Virulent (V) isolates of Cryphonectria parasitica were readily recovered from both sunken cankers and swollen superficial cankers on American chestnut trees in the southern Appalachians. Hypovirulent (H) isolates of C. parasitica made up 38% of the population in six swollen superficial cankers on one isolated tree in Tennessee but were infrequently recovered from 9 sunken and 52 swollen superficial cankers from North Carolina, Virginia, and Italy. A cluster analysis was used to group V isolates by vegetative compatibility (v-c) and by conversion susceptibility. Isolates from the Tennessee tree had four distinct v-c groups identified by the merge-barrage response and each canker averaged 2.7 v-c groups. Forty-one cankers on 19 trees near Buchanan, VA, yielded 2.3 v-c groups per canker.

AN - 13869353; 716241 AB - Incidence of sporocarps of Fomes fraxinophilus on living green ash (Fraxinus pennsylvanica ) in Nebraska woodlands was determined by examination of 7,066 trees on 361 sample plots in 10 multicountry forest inventory units. Infected trees were found on 55% of the plots and in 55 of 64 counties sampled. A mean of nine sporocarps per tree were present on 1,019 infected trees. Incidence of F. fraxinophilus increased in a straight-line relationship with trunk diameter. It is estimated that 10 plus or minus 0.8% of the more than 20 million living green ash trees in Nebraska woodlands have sporocarps.

AN - 13869303; 718868 AB - Developing kernels of eight maize single crosses (Zea mays ) were inoculated with Aspergillus flavus in four environments and assayed for aflatoxin. The eight crosses were from two A-inbreds crossed with four B-inbreds, as labeled for convenience. The two A-inbreds were about 88% related and there was little difference between their aflatoxin means. Two of the B-inbreds averaged 22,168 and 17,915 ppb and had significantly less aflatoxin than the other two B-inbreds, which averaged 40,011 and 32,006 ppb. This study indicated that resistance to the accumulation of aflatoxin in developing kernels was under genetic control, that differences between duplicate assays were small, that variability among ears per plot was large, and that the greatest contribution to stable and economical estimates would come by increasing the number of replicates and keeping the number of ears to a low level of about five ears per plot.

AN - 13868141; 716044 AB - Kramer-Collins 7-day spore samplers were used to study availability, viability, and movement of Puccinia recondita and P. graminis urediniospores throughout the year in the Great Plains. From October 1974 to August 1977, the longest period of consecutive days that no spores were trapped at any of the Great Plains locations (Renner, TX; Altus, Goodwell, and Stillwater, OK; and Parsons, St. John, Garden City, Hays, and Manhattan, KS) was 19 for P. recondita and 18 for P. graminis . Estimated viability of urediniospores trapped was 61% for P. recondita and 58% for P. graminis . Viable inoculum was present in the central Great Plains wheat-growing areas most of the time samples were taken; therefore, epidemic development was largely dependent on favorable weather and host-parasite combinations. Forecasted wind trajectories were used to indicate spore movement patterns; however, the authors were unable to develop significant statistical models of urediniospore movement.

AN - 13868060; 716027 AB - Reactions to early leaf spot, caused by Cercospora arachidicola , were evaluated at Perkins, OK, in 1981 on 151 peanut entries representing genotypes of cultivated Arachis hypogaea , wild species of Arachis , and hybrids. Plants were grown in single-row, 3-m plots that were irrigated weekly (2.5-3 cm); leaf spot was evaluated 115-120 days after planting. A subjective scale index of 1-5 (low to high response) was used to describe each of the following criteria: 1) amount of leaf necrosis, 2) degree of sporulation of C. arachidicola , and 3) leaf defoliation. A leaf spot reaction index (LSRI) for each entry was obtained as the product of the leaf necrosis and sporulation indices, where the lowest and highest values of the LSRI were 1 and 25, respectively. The Kruskal-Wallis one-way analysis of variance by ranks and multiple-comparison test were used to test the equality of the effects of genotypes on these criteria. The Spearman rank correlation for each pair of criteria was calculated for each genotype. Significant positive correlations between LSRI and defoliation and between amount of leaf necrosis and defoliation was obtained for all genotypes. Information obtained from this statistical analysis is useful for evaluating resistance of peanut entries to C. arachidicola in field plots on a yearly basis.

AN - 13866958; 716411 AB - In feeding preference tests young workers of Apis mellifera were given a choice between two pollen diets: one consisted of pure pollen from Populus fremontii, Prunus dulcis, Larrea tridentata, Cereus gigantea , or Prosopis velutina and the other consisted of a mixture of equal weights of these five pollen species. The pollen mixture was significantly preferred over Populus, Prunus , and Larrea pollens and was about as preferred as the other two. Moreover, the preference for the mixture was significantly greater than the average of the preferences for all five species. These results indicate that A. mellifera exhibits a preference for pollen polyphagy rather than monophagy. JF - Journal of the Kansas Entomological Society AU - Schmidt, JO AD - Carl Hayden Bee Res.

Dilution was not a factor because race 2 alone at 1 x 10 super(6) conidia per milliliter was pathogenic but the race 2 component in the mixture at 4 x 10 super(6) conidia per milliliter was relatively, or usually, completely nonpathogenic. In spray-inoculation experiments, most cultivar Arc seedlings were protected from race 2 by prior inoculation with race 1. The survival rate of Arc seedlings inoculated with a mixture of races 1 and 2 was much higher than that of seedlings inoculated with race 2 alone. Analysis of plants capable of being protected from race 2 in mixtures, or by protective sprays with race 1, demonstrated race 1 resistance was a requirement for the race 2 protection phenomenon to be operative.

Sooty male migration was recorded in fields surrounding three sides of the male release field. Developmental times observed in the field were compared with results from a computer program which used daily maximal-minimal temperatures to derive developmental rates.

AN - 13865956; 716338 AB - Hylaeus bisinuatus was induced to nest in glass tubes inserted into observation boxes where its nesting biology was studied under greenhouse conditions. Results of these observations yielded detailed descriptions of nest architecture, cell construction, cell provisioning, egg deposition, embryogenesis, hatching, and immature development. Daily and seasonal activities are also discussed. An embryological feature of Hylaeus (90 degree rotation of the late embryo) was discovered and associated with hatching strategies and the side position taken by developing immatures on their provisions. Comparisons with other colletidae bees, etc., demonstrated that representative genera of the five subfamilies of the Colletidae also exhibit this characteristic. This derived embryological phenomenon has not been reported elsewhere in the Apoidea or Hymenoptera and may indicate a monophyletic origin of the family Colletidae as presently understood.

AN - 13864358; 716374 AB - Crop management effects on the renovation of municipal wastewater effluent were studied in a 6-year field experiment. A randomized split-plot block design was used, with corn (Zea mays L.) and forage grasses (reed canarygrass, Phalaris arundinacea L.) as crops and effluent application rates of none. similar to 0.05, and similar to 0.10 m week super(-1). Nitrogen, phosphorus, potassium, sodium, and chloride were measured in percolating soil water during 5 years under corn and 3 years under forage grasses to assess the quality of renovated wastewater. Nitrogen concentrations were generally below 10 mg L super(-1), with total applications ranging between 200 and 970 kg N ha super(-1). Nitrogen concentrations also were consistently lower under effluent treatments as compared with fertilized controls and lower under forage crops than under corn. Nitrogen levels increased significantly with increased application rates, especially under corn crops and only occasionally exceeded 10 mg L super(-1) during early and late season when applications surpassed crop uptake demands.

AN - 13861710; 714684 AB - Cattle feedlot waste (FLW) was applied to irrigated continuous grain sorghum grown on Pullman clay loam over an 8-yr period. The FLW applications increased the total, inorganic, organic, and available P content and decreased the P sorption index of surface soil. Amounts of P in the surface soil were highly correlated with the total amount of FLW-P applied and time since the last application. The proportion of total P as inorganic P increased with large FLW applications. Increases in the amounts of surface soil inorganic and organic P with FLW application were due mainly to increases in labile fractions of these P forms. When FLW applications were stopped, however, soil organic P contents decreased to retreatment levels more rapidly than inorganic P contents as a result of labile organic P mineralization. Increased P contents of surface soil following FLW applications will increase the potential for soluble and sediment-bound P to be transported in runoff.

Additionally, beneficial as well as deleterious genetic and epigenetic changes are promoted by the in vitro procedures. The majority of plants recovered from anther calli of the cultivar "Calrose 76" were similar to the starting cultivar but plants regenerated from microspore calli had a wider range of responses than controls for several characteristics. Plants with larger seeds, higher levels of seed protein, shorter stature and more highly tillered than the starting cultivar were obtained from selfed anther-derived plants.

Nesting females exhibited a significant preference for end holes of the widest diameter and deepest bore. Predators and parasites were the primary cause of immature mortality. The sex ratio of progeny was strongly biased towards females, particularly in end holes. Hoplitis fulgida placed male progeny in outer cells and female progeny in inner cells of the nest. Nests in the preferred end holes had significantly more cells a higher percentage of surviving progeny, a significantly greater percentage of female progeny, and significantly larger progeny of both sexes, than did other nests.

Diurnal observations were made each week during 2 successive days from hatch to pupation (May to September 1979). The behavior of all six instars was compared to determine temporal periodicities and habitat relationships. The motility of the larvae increased with their development. Larvae hatched from their egg masses in shrubs and forbs and moved into grass habitats. The 6th instars were most active just before pupation when they returned to woody plants to pupate. Larvae resting periods were from late morning throuth the late afternoon. JF - Environmental Entomology AU - Hansen, J D AU - Ludwig, JA AU - Owens, J C AU - Huddleston, E W AD - USDA-ARS, Crops Res.

AN - 13854433; 713664 AB - The perennial grasses of the Triticeae tribe-Agropyron, Elymus, Leymus, Psathyrostachys, Pascopyrum , and Elytrigia - are especially well suited to wide-hybridization and induced-polyploid breeding because most of these grasses are themselves polyploids with a history of interspecific hybridizaiton. Breeding strategies were developed after taking into account the genomic constitution and polyploidy characteristics of each genus. The following strategies were given the highest priority: Agrophyron (C-genome species) - hybridize induced tetraploids with natural tetraploids; Elymus (SH-genome species) - hybridize and introgress among tetraploid taxa; Leymus (JX-genome species) - hybridize dodecapolid L. angustus which other Leymus species; Psathyrostachys (J-genome species) - produce induced tetraploids from diploid taxa; Pascopyrum (SHJX-genome species) - synthesize new allooctoploid taxa; and Elytrigia (a genomically diverse group of species) - hybridize S-genome tetraploids with hexaploid Elytrigia repens . Breeders must be very discriminating in their choice and application of strategies to justify the extra risk, time, and expense associated with nonconventional breeding programs. JF - IOWA STATE J.

AN - 13841694; 697535 AB - The extent of progressive decrease in concentration of the herbicide picloram in intermittent streamflow was determined during runoff-producing storms. Maximum concentrations of picloram were 48 and 250 mg/m super(3) in initial runoff water leaving a sprayed 8-ha area in 1978 and 1979. Concentration decreased with distance from the treated area in proportion to the size of adjacent, untreated watershed subunits, which contributed runoff water to streamflow. Picloram concentrations usually decreased with each successive runoff event; an exception occurred when unusually large quantities of runoff diluted concentrations to levels less than those observed in the succeeding event. About 6% of the applied picloram left the treated area during a period of 1 month when conditions were especially conducive to transport of the herbicide in surface runoff water.

The relationships between rain intensity and the amount of methyl parathion (MP) and EPN (O-ethyl O-(p-nitrophenyl) phenylphosphonothioate) washed from cotton plants during the months of high intensity thunderstorms was examined. The MP and EPN runoffs were measured by the use of a multiple-intensity rainfall simulator. It was found that the rainfall intensity did not affect MP and EPN runoff but the rainfall amount did affect runoff. This information simplifies the modelling of MP and EPN movement during natural storms.

This subsurface runoff often passes through a band of riparian forest before becoming steamflow. It is hypothesized that the riparian ecosystem acts as a nutrient sink and reduces the concentrations and loads of nutreints in the shallow aquifer before the nutrients reach the stream channel. Concentrations and loads of NO sub(3)-N, NH sub(4)-N, organic N, dissolved molybdate-reactive P, total P, Ca, Mg, K, Cl, land SO sub(4)-S were measured in shallow phreatic wells at 37 locations on an agricultural watershed near Tifton, Ga. Total water volume moving off the watershed in subsurface flow was <1% of streamflow with corresponding small amounts of nutrients. Nitrate-N, Ca, and Mg had significantly higher concentrations in field wells than in forest or streamside wells. Concentrations of Cl were not reduced as water moved from field to forest. Processes within the riparian zone apparently converted primarily inorganic N from fields into primarily organic N in streamside wells. Concentrations differences between field and forest wells indicated the riparian forest's ability to act as a sink for NO sub(3)-N, Ca, Mg, K, and SO sub(4)-S. Due to their role as nutrient sinks, riparian forests are important in maintaining stream water quality on agricultural watersheds.

Worker bee offspring from these matings were evaluated for a variety of characteristic, and heritabilities (h super(2)) and phenotypic and genetic correlations were estimated using the European data, the Africanized data, and the combined data. Phenotypic correlations were generally less than the corresponding genetic correlations. For some traits, the three estimates of the parameters were very different. Heritability estimates were sufficiently high to expect success in a selection program for gentler, more productive bees.

AN - 13827752; 688244 AB - Guidelines for improving scaled quail (Callipepla squamata ) habitat have emphasized the need for daytime resting cover. Strategically located roosting cover may be equally important for protection from predators and weather. Klimstra and Ziccardi (1983) considered lack of suitable roosting cover as limiting to northern bobwhites (Colinus virginianus ) in some areas. With the exception of the generalized description of roosting cover given by Wallmo (1956), roosting habitat of scaled quail has not previously been defined. This paper describes the floristic and structural features of roots habitat used by scaled quail during winter and spring, a period when cover frequently is limited.

The high hazard flood retarding dam at site 19 was completed in 1971 and a full investigation was carried out in 1980 after seepage was reported at the left toe of the dam. After geologic and engineering investigations, the dam was breached and a detailed study was made of the embankment, cutoff trench and drains of the 65 foot high earth fill structure. High permeability rates in the embankment appeared to be caused by hydraulic fracturing during drilling operations. The drains had a relatively low permeability, and an old landslide in the lower left abutment had not been recognized during construction so that the cutoff trench had not been extended through the slide material. The dam was redesigned and rebuilt and it was concluded that a catastrophic failure had been unlikely. The seepage was not water passing through the embankment but resulted from water from the pool and some groundwater moving through the left abutment.

AN - 13807754; 661394 AB - Specific electrical conductivity (SEC), total dissolved solids (TDS), and silica (SiO sub(2)) are groundwater quality parameters routinely measured in a laboratory. Electrical conductivity measurements are made quickly and are less costly than TDS measurements. Once the relationship between the parameters is determined by regression analysis, TDS can be estimated quickly from the SEC and SiO sub(2) measurements. Water quality data from 25 city wells in Fresno, California, and historical groundwater quality data from the adjacent San Joaquin River/Kings River alluvial interfan, the Kaweah River alluvial fan, and the Kern River alluvial fan were used in this investigation. For the specific hydrologic areas studied, the model's TDS predictive ability is improved when SiO sub(2) is included with SEC as the independent variables.

AN - 13793638; 658793 AB - Plants of near-isogenic wheat lines Thatcher (TC), LR16(TC), and LR18(TC) were inoculated with urediniospores of culture UN02-64A of P. recondita f.sp. tritici at seedling, heading, and anthesis stages. Following inoculation, seedings were maintained at temperatures ranging from 15.6 to 29.4 C, and plants inoculated at heading or anthesis were maintained at temperatures ranging from 21.1 to 29.4 C. Rate of growth of colonies and uredinia was generally fastest at moderate temperatures on cultivar TC and and on seedlings. Temperatures below 21.1 C greatly reduced fungal development on seedlings of LR18(TC). Colony growth was linear with time within each temperature at each growth stage. The number of urediniospores produced per unit area of uredinium was not a satisfactory way to evaluate environmental, host age, or host resistance effects. The number of urediniospores produced per unit area of colony was slightly more useful in evaluating those effects.

H. sativum was isolated from switchgrass in six counties. Isolates of H. sativum from switchgrass differed in virulence on switchgrass and other hosts. Isolates from switchgrass and deertongue grass (Dichanthelium clandestinum ) were about equally pathogenic on the two species and on other susceptible hosts. Caucasian bluestem (Bothriochloa caucasica ) was not susceptible to H. sativum from either host. Corn (Zea mays ) and rice (Oryza sativa ) were moderately to highly susceptible to H. sativum from switchgrass. JF - Plant Disease AU - Zeiders, KE AD - USDA, ARS, U.S. Reg. Pasture Res.

AN - 13788350; 647800 AB - Twenty races were identified from single-uredinial isolates of U. phaseoli by using 19 differential bean cultivars. Although these races did not include all of those occurring on beans in the United States, a few major races were included. At least 18 of these races differ from any previously described races of this fungus. A major objective of this research was to obtain races that were virulent on bean cultivars with broad rust resistance. Among such cultivars, Aurora, NEP-2, Olathe, and Mexico 309 are susceptible, respectively, to 9, 6, 6, and 3 of these 20 races. A high degree of variability and great potential for races that break host resistance exist in U. phaseoli . The most resistant cultivar of more than 400 tested was Compuesto Negro Chimaltenango, which was resistant to all 20 races. JF - Plant Disease AU - Stavely, J R AD - Plant Pathol.

All three fungi were also isolated from other Elymus spp. S. spraguei has not been previously reported on beardless wildrye (E. triticoides ), Altai wildrye (E. angustus ), or European dune wildrye (E. arenarius , and P. trichostoma has not been previously reported on field collections of basin wildrye (E. cinereus ), bearless wildrye, or European dune wildrye. Five isolates of S. spraguei , two from Russian wildrye and one each from basin wildrye, Siberian wildrye, and bearless wildrye, were pathogenic on a wide range of grass species and could be reisolated from each. Among 25 inoculated grass species, leaf necrosis was most severe on Russian wildrye and beardless wildrye, followed gy Siberian wildrye and tetraploid crested wheatgrass (Agropyron desertorum ).

The cultures of E. graminis and P. recondita were chosen so that most the virulence genes found in the eastern United States were represented. Powdery mildew and leaf rust ratings were bimodally distributed, with high ratings outnumbering low ratings by as much as 1.8 to 1. Ratings of leaf symptoms caused by S. nodorum were skewed toward resistance and susceptibility outnumbered resistance by as much as 4.1 to 1. Reaction to S. nodorum was correlated with reaction to E. graminis. Triticum carthlicum may be a source of resistance to E. graminis, T. monococcum may provide resistance to E. graminis and P. recondita , and resistance to E. graminis, P. recondita , and S. nodorum may be found in the T. timopheevi population. Nine accessions had resistance to all three pathogens. Seven of these were highly pubescent. The association of resistance to leaf pubescence may affect the expression of any resistance transferred to T. aestivum .

A sedimentation survey, cesium 137 analyses, and soil loss calculations were used to estimate the average rate and variability in rates of sediment deposition in Silver Lake, and soil loss rates in the Silver Lake drainage area. The rates of soil loss and sediment deposition have been relatively constant since 1957. Silver Lake is estimated to be filling at an average rate of 43.75 acre ft. This rate gives an average annual water depth loss of 0.4 cm. If this rate of sedimentation is allowed to continue, Silver Lake will be filled with sediment in 280 yr. Continued sediment deposition in Silver Lake will induce flora and fauna changes.

We reproduced 18 sounds-including those of children, songbirds, construction equipment, automobiles, aircraft, and wind-for college students serving as evaluators at field sites ranging from a forest to a downtown street. In two other procedures, settings and sounds were described in a questionnaire, or were presented using photographs and tape recordings. All.three procedures produced similar results; natural and animal sounds had enhancing effects on evaluations of the heavily wooded natural and residential sites, and other sounds had detracting effects on the same sites. The sounds were relatively neutral in effect at two downtown streets, where traffic sounds were found to be most enhancing. The results show that the interaction of a setting's visual and acoustic characteristics significantly influences evaluations of that setting, and that appropriateness of sounds only partly accounts for their influence on setting quality.

The minimum elevation of the top of a pond embankment should be 1 ft above the water surface. The design height should also allow for wave action. Minimum embankment top widths depend on the height--6 ft wide for an embankment 10 ft or less in height, 15 ft wide for an embankment 35 ft or more in height. Spillways are necessary if runoff has no natural escape. Wells are the ideal water supply; the minimum rate should be 15-25 gal per min per surface acre. Depth depends on the species and climate. Most desirable depths in warm climates are as follows: channel catfish, 4-6 ft; crawfish, 1.5-2 ft; minnows and other bait fish, 4-6 ft; and trout, 3-5 for flowing water and 10-12 ft for still water. Extra depth should be allowed for ponds in cold climates. Pond bottoms should be smooth and sloped toward the outlet at a minimum of 2 ft per 100 ft.

Natural sediment is a heterogeneous mixture of primary particles and aggregates having nonuniform distributions of diameter and density. Coal as aggregate substitutes and sand were studied both as separate homogeneous sediments and combined as hetergeneous sediment mixtures. Specific gravity was more important than diameter in the transport and deposition of different particles types in a mixture. The particles with the lower specific gravity traveled much further downslope before being deposited than did the particles with the higher specific gravity. Before considerable sediment was deposited on the slope, most of the sediment yield was particles having the smaller specific gravity. As deposited sediment accumulated, the portion of sediment yield consisting of sediment with the larger specific gravity increased.

Using readily available hydrometeorological data, the model predicts average daily water temperature and diurnal fluctuations within a stream network. Various solution techniques are available ranging from desktop calculator programs designed for simple applications to a sophisticated computer program designed for complex systems, large data volumes, or repetitive applications. The application of the model and possible interpretations of its results are discussed with respect to two endangered fish species in the Upper Colorado River Basin.

A comparative analysis of snow pillow sensors and precipitation gage catch in the variable snow-pack environments in the Colorado and New Mexico Rockies for a five-year period (1978-82) is provided. Telemetered data are compared to ' ground truth ' measurements and an explanation given for some anomalous events. During this five-year period, there were several extreme years of record providing a wide range of hydrometeorological conditions under which to examine system performance. Telemetered data are found to be of sufficient accuracy for water supply forecasting applications. A discussion of second generation units incorporating a microprocessor programmed to perform numerous functions, including computing minimum, maximum , and average air temperature, as well as event recording is presented. A subtelemetry network has been developed to add more remote sites to the SNOTEL system without adding more costly meteorburst transceivers.

Sixty per cent total chemical oxygen demand removals were routinely obtained with both systems. In addition, there is evidence that the anaerobic effluents are readily degraded aerobically and that methane gas recovery plus heat exchange should minimize or negate the energy input needed to maintain the reactor at 37 C. Hydraulic retention times of < 24 hrs. were demonstrated with the anaerobic filters (AF). There is also evidence that anaerobic treatment processes are inherently stable. Data generated by the anaerobic contact (AC) and the AF treatment of tannery wastes showed the anaerobic processes tested to be resistant to hydraulic variations and upsets. On several occasions both the AF and the AC organisms were exposed to oxygen through mechanical difficulties. Restarting either system was generally rapid and required only a few days. Despite reactor sulfide levels as high as 600 mg/l, normally considered toxic, the AC system continued to produce methane. Problems observed in this work on anaerobic treatment should not be ignored. Initial anaerobic startup requires a long period of time (up to six mo). The tannery wastewaters studied presented a particular problem due to the formation of inorganic precipitates. They were sufficient to clog the AF and close down the space between discs on the bench scale rotating biological contactors. This result would favor a suspended growth AC process over the AF for tannery wastewaters. JF - Proceedings 38th Industrial Waste Conference, West Lafayette, IN, May 10-12, 1983.

The volume fraction of water in the films and the occupied pore volumes were determined from refractive index and thickness changes. The dependence of the refractive index on water absorption is related to a competition between two processes: ' pore filling ' with no film expansion and ' free expansion ' where the film expands to accommodate the added water volume. The hydration properties of these membranes are affected by degree of acetylation, casting temperatures and annealing treatments. Annealing CA398 membranes at 180 degrees C decreases film water concentration by reducing ' free expansion'. Annealed CA398 membranes that were tested in a reverse osmosis cell had high salt rejection compared to unannealed films. The hydration characteristics of a polyimide membrane are compared to cellulose acetate membranes. Raman measurements of unannealed CA and CTA membranes and annealed CA membranes using the waveguide technique showed that OH groups in unannealed polymers are all hydrogen bonded and are highly accessible to absorbed water. The intergrated OH stretching intensity in the region of 3050 to 3800 cm super -1 was found to be linearly dependent on water concentration. Water absorbed in the ' pore filling ' stage is weakly hydrogen bonded to C=0 groups in the polymer and water absorbed in the ' free expansion ' stage is hydrogen bonded like bulk water at equivalent 90 degrees C. Analysis of the C=0 stretching region indicated that each of the OH groups of a water molecule are H-bonded to a different C=0 group of the polymer in the ' pore filling ' stage of absorption.

Fabric was treated with one of the metal compounds and oxytetracycline, tetracycline, or pyrithione (1-hydroxy-2- pyridinethione), in the same bath or separate baths, by conventional pad-cure pro cedures. At least one such process using each antibacterial agent served to give the fabric excellent bacteriostatic activity against Staphylococcus aureus. Some of the fabrics treated with one of the tetracyclines still completely inhibited bacterial growth after twenty launderings. Processes using titanium compounds were less satisfactory than those using Al sub( 2)(OH) sub(5)Cl because of problems encountered during application to the fabric.

Determination of the yields of total particulate matter and analyses of individual smoke components, including nicotine, phenolics, acids, and the humectant, glycerol, demonstrated significant changes in smoke composition as related to intensity and frequency of inhalation. Physical obstruction of tipping paper ventilation, by negating the effects of air dilution of smoke, resulted in increased smoke deliveries similar to those observed when puffing volume and frequency were increased.

Phosphorus loss coefficients were estimated using the Universal Soil Loss Equation for runoff and soil erosion and phosphorus buffer curves for labile P. The curves relate soil and solution P concentrations, assuming chemical equilibrium. The buffer curve approach using labile P instead of the traditional total P has several advantages, including the fact that labile P is more closely related to algal growth, soil P fertility, and crop productivity than total P. The model was applied to Greenlane Reservoir, the most severely eutrophied water body in Pennsylvania. The target total P level was established at 65 micrograms per liter, far less than the present 262 micrograms per liter, of which 60% comes from point sources and 40% from nonpoint sources. The model produced a variety of crop and conservation practices for four combinations of point-nonpoint labile P control. Some suggested changes were wider use of contour and no-till, shifting more acreage to hay production, and growing alfalfa on the steeper slopes.

Annual average data from the Current Population Survey were used to determine the effect of changes in the industry structure of women's employment on their experience during the post-1980 recessionary period. It was found that while the premise of last-hired, first-fired held true, the greater effect of economic downturns on women's unemployment did not occur in 1980-1982. Women's & men's unemployment rates in 1982 were almost equal in both metro & nonmetro areas, & the increase in unemployment was actually greater for men than women. In addition, if the changes in industry structure had not occurred, women's unemployment would have been over 1% higher than the actual 1982 rate.

However, certain limitations & restrictions must be considered when using census farm labor data. Because of the seasonal nature of agriculture, many farmworkers are excluded from decennial census farm labor categories if they were not working on farms at the time of the census. While 1980 census data on farm labor are not presently available, data from the US Dept of Agriculture's Hired Farm Working Force Survey of 1981 can be used to identify the farmworker population excluded from the census & to examine the potential effects of this omission on the number & characteristics of farmworkers reported in census publications. Discriminant analysis is used to examine the SE & employment differences between farmworkers employed at some time during Mar (the group measured by the census) & those employed at other times of the year. Results indicate that as many as 63% of persons doing hired farmwork during the year could be excluded from the census farm laborer category. The characteristics of workers in Mar differ significantly from other workers, suggesting that census data are more likely to describe those workers who are attached to farmwork as an occupation rather than as a LF activity. Thus, census data could be useful in studies comparing occupational classifications, but would be misleading if used in research or administrative accounting procedures that seek to measure or characterize those people who work on the nation's farms.

Aggregate-level data are from the US Census of Population & Agriculture & from other federal sources. The findings demonstrate that both migration & intensification of agricultural production are positively related to increased farm land value. These relationships are strongest in moderately developed counties where farm-nonfarm competition is thought to be greatest. The effects of sociodemographic factors other than migration are less clearly related to price changes in farm land.

The two small farm definitions used by the US Dept of Agriculture differ in that the first is based on the farm household & the second on the farm as a business enterprise. Under the first definition, a small farm is any farm household with a family income of less than the nonmetropolitan median family income for the South ($16,866). The second definition of a small farm is any farm business with annual gross value of sales less than $20,000. Small farms under the first definition were mostly full-time operators, mixing crop & livestock, with low net farm incomes. They participated in governmental programs, & operators & household members worked very little off-farm. Under the second definition, small farms tended to be livestock operations that were fully owned, with positive net farm & off-farm incomes. They also tended to have low rates of participation in governmental programs, with a majority of operators & household members working off-farm.

Whether newcomers voice preservationist or progrowth sentiments has implications for community conflict & the course of future growth & change. The growth & development issue has been addressed in past studies on turnaround migration. These studies have been descriptive in nature, however, with little attention given to factors determining immigrants' stances on growth & development. To alleviate this gap in the literature, a multivariate analysis framework is used to examine the relative importance of several objective & subjective determinants of community change orientations among metropolitan origin migrants to high growth nonmetropolitan counties of the Midwest. Earlier research has shown that metropolitan origin immigrants are not monolithic in their views on growth & development alternatives. Thus, the determinants are examined for various growth & development options.

The presence of wool in untreated blend fabrics caused burning rates to decrease and oxygen index values to increase as wool content increased in the blends. These effects were also observed in cotton/ wool blends treated with low levels of the Thps-urea-TMM flame retardant, but were less pronounced in fabrics treated at high levels. Thermogravimetric analyses were conducted to study the thermal degradation of the treated and untreated fabrics. The presence of wool in treated blend fabrics did not sig nificantly change strength retention, area shrinkage and wrinkle recovery values in comparison to similarly treated 100% cotton fabrics.

Molar fractions of nine primary, volatile pyrolysis products were determined, accounting for 82-89 mole percent of the products. Three classes of volatile products were distinguished on the basis of the response of the product fractions to add-on of the flame retardant. Increasing add-on decreased the anhydroglucose fractions. Small add-ons increased the "furan" fractions and large add-ons decreased them. Nonfuel fractions increased with increasing add-on. Inverse relations were found between anhydroglucose fractions and water fractions and between "furan" fractions and carbon dioxide fractions. The flame retardancy of the cotton fabrics had the best correlation with the water fractions. These results are compared and contrasted with data from the pyrolysis of cotton fabrics treated with another flame retardant, THPOH-ammonia.

Cooperative planning by USDA with state and federal agencies has been underway since 1973 to reduce salinity problems in the Colorado River Basin. The most important beginning point in any planning effort is to accurately locate and define the magnitude of the problem. Salinity problems are not just a concern for those in the Colorado River Basin. Every state in the West has some high water table problems. Associated with high water table, in many cases, is a soil salinity problem which affects crop production on 10,300,000 irrigated acres (4,171,000 ha). Salt concentrations are increasing steadily in some of the nation 's most productive soils. The rich San Joaquiin Valley in California could eventually lose 2 million acres (810,000 ha) to salinization. Other areas with significant problems include the valleys of the Rio Grande and Pecos River, closed river systems in the Great Basin, the Arkansas River, tracts in Texas and Oklahoma, and tributaries of the Upper Missouri. Several ongoing programs (Wellton-Mohawk USDA, and Agricultural Conservation Program USDA) are providing technical and financial assistance to improve irrigation systems and management. Implementation plans will generally include the identification of financial and technical assistance available to the land owner or operator. USDA salinity programs are funded by a variety of authorities. USDA salinity control planning of needed on-farm irrigation improvements on individual units is essentially completed. Implementation is progressing on 3 of the 12 units. The USDA on-farm salinity control program is receiving positive reviews for cost-effectiveness, and the planning experience gained in this activity will be most helpful in formulating and justifying future salinity control programs.

In 1961, the concentration increased to nearly 1,400 mg/L and to more than 1 ,500 mg/L in 1962. Among other things in the Colorado River Basin Salinity Control Act, the United States agreed to adopt measures to assure that water delivered to Mexico would have a salinity concentration of no more than 115 mg/L over the average quality of water arriving at Imperial Dam. From 1973 to 1979, the average quality of water arriving at Imperial Dam decreased from 846 mg/L to 809 mg/L probably due in part to the construction of upstream storage reservoirs on the Colorado River. However, irrigating with water having salinity concentrations at this level can reduce agricultural yields to about 80% of maximum potential yields. Studies indicate that the Grand Valley annually contributed about 526,000 tons (metric of salt to the Colorado River. A study by the Soil Conservation Service shows that 270,000 tons is attributed to onfarm irrigation. It is estimated that onfarm improvements might effectively reduce the annual load by 120,000 tons. The onfarm program for salinity control has three components. These are: (1) Installing structural measures to reduce seepage from unlined earthen irrigation ditches; (2) Improving irrigation water management practices to reduce deep percolation from field irrigation and to enhance uniformity of irrigation applications; and (3) Implementing a monitoring and evaluation program to assess the effectiveness of installed salinity control measures. Key elements of the program are to measure surface inflow and runoff to determine the amount of water infiltrating into the Ground. These data will be used to compute salt loading under improved management practices and will help identify further improvements needed in management practices to achieve objectives of the salinity control program. Salt loading evaluated under improved management will be compared with loading evaluated during planning to show effectiveness of the program.

All work was implemented on private land. The Ute Indian Tribal Council, in a letter dated April 28, 1978, authorized the inclusion of Indian lands. The Uinta Basin is in northeastern Utah and covers parts of Duchesne, Uinta, and Wasatch Counties. The area has two major drainages, Ashley Cree-Brush Creek and Duchesne River. These drainages and their tributaries provide all the water used for irrigation. About 50,000 ha of irrigated land were treated under the salinity control program. It is estimated that 69,475 metric tons of salt-loading from the irrigated area can be eliminated from the Colorado River system annually. This translates to 10.3 mg/L at Imperial Dam. Based on downstream losses of $513,300 per mg/L (January 1982), annual benefits are $5,286,990. On-site benefits will increase because of lower operating costs and higher crop yields. These factors will be determined by the monitoring and evaluation team. The experience gained in the Uinta Basin will provide valuable data and methodology for future on-farm salinity control projects. The ability of all units of government, agencies, and groups to cope with organizational and coordination problems has been outstanding. This project reemphasizes the ability of people to work together for a common cause. (See also W87-05165) (Lantz-PTT) JF - Salinity in Watercourses and Reservoirs.

A group of 60 Illinois soils were selected for possible evaluation. Five were studied at sites where subsurface drain pipe systems had been installed previous to the study. Plots were irrigated to bring the water table to the soil surface. Irrigation was stopped, and then water table depth and drain flow measurements were made periodically until the water table midway between drains was at a depth of 300 mm. Drainable porosities, hydraulic conductivities, and recommended pipe drain spacings were computed. It was concluded that the average measured drainable porosities for Bonnie, Bryce, Darwin, Piopolis, and Wabash soils ranged from 0.0340 to 0.0483. The field effective hydraulic conductivities ranged from 19.0 to 63.2 mm/h. Only Bonnie had values with USDA published ranges; the other soils had higher measured values. The recommended drain spacings were: Bryce, 24.2 m; Bonnie, 13.9 m; Wabash, 12.8 m; Darwin, 10.8 m; and Piopolis, 13.1 m.

B. Lord AN - 18983621; 8400414 AB - In the original paper (Water Resources Bulletin, Vol 18, No. 2, p 271-277, 1982) the idea was presented that limiting water supply does not inhibit urban growth. Various studies were cited to show that growth occurs in areas where water supplies are limited. In an examination of residential use of water, the original author states that substantial savings in water use by householders. The argument is stated that industrial and commercial growth can be accommodated within existing municipal supplies if residential demands can be reduced. The discussant maintains that the suggestion to homeowners that lawns can survive on 70% of the water they are capable of taking up is illusory; that to put watering or waste of water on lawn watering on a gallon-per-day basis is clearly inaccurate and misleading, as residents in Colorado 's Front Range cities water their lawns only rarely at present anyway; and that raising prices for water could turn out to be a lawn tax, with far reaching effects on the older, fixed-income area residents rather than on new members of the community. The discussant suggests that the Denver Water Board pursue its historic course of expanding the water supply. While this course has been criticized by certain environmental groups, the disrupting effects of this course are no worse and perhaps less burdensome than depriving urban areas of adequate water.

Part I, Water Sorption and Refractive Index of Cellulose Acetate AN - 18960487; 8405048 AB - A new technique of integrated optics is applied which allows investigation of the swelling and water absorption properties of dense symmetric films of 0.25 to 4 micrometers in thickness. The dependence of water absorption of membranes of cellulose acetate on relative humidity was determined by measuring small changes in their asymmetric waveguide properties in the visible spectral region. Simultaneous measurements of changes in film thickness provide a direct method for obtaining the change in film volume as a function of water concentration and a new measure of polymer porosity. Data are presented for a typical film fabricated from celluose acetate which illustrate the usefulness of studying water absorption by integrated optics techniques. One conclusion inferred from an interpore spacing of 50 to 60 Angstrom units is that it should be hypothetically possible to increase the number of pores in cellulose acetate membranes without increasing pore diameter and still maintain sufficient polymer interactions for stability under conditions of higher water content.

AN - 15552658; 398443 AB - Seedborne and soilborne organisms, both flora and fauna, acting singly or in combination, produce the seedling disease complex of cotton. Most of the pathogens involved are ubiquitous fungi that are associated with many other hosts as well as with cotton wherever it is grown. Pathogenic nematodes are often associated with these fungi, and the combination of these organisms can cause more severe disease problems than fungi alone. Each pathogen produces effects that become a complex of interrelated symptoms caused by several organisms simultaneously attacking seed and seedlings. The disease syndrome includes various amounts of preemergence rotting of seed and seedlings, chlorosis and necrosis of seedlings both before and after emergence, stunting, and witting. The incidence of seedling disease is influenced primarily by adverse temperature and soil moisture. Any condition favoring faster development of the pathogen than the host, however, can be detrimental. JF - Plant Disease AU - Minton, E B AU - Garber, R H AD - ARS, USDA Cotton Physiol. & Genet. Res.

AN - 15548224; 398380 AB - Bacterial wetwood of American elm (U. americana ) is associated with positive intrastem gas pressures within affected wood. Comparative data were obtained on elemental gas composition and seasonal variation in the magnitude of gas pressure in nondiscolored sapwood and discolored wetwood. Gas composition was determined by gas chromatography, and gas pressures were monitored with a gauge cock. No positive gas pressure was observed in nondiscolored sapwood. Positive gas pressures in discolored wetwood increased from May through August, then declined. Means gas composition in sapwood and wetwood was, respectively, CO sub(2), 5.4 and 8.8%; O sub(2), 18.9 and 7.2%; N sub(2), 74.7 and 32.8%; and CH sub(4), O and 47.2%. CH sub(4) levels were significantly higher and O sub(2) and N sub(2) levels significantly lower in discolored wetwood, where bacteria abound, than in nondiscolored sapwood, where bacteria are rare.

AN - 15547316; 421839 AB - Two groups of five experienced scorers estimated percent leaf area spotted by matching orchardgrass leaves infected by Stagonospora arenaria against published area diagrams. Actual area of spotting was determined by weighing paper replicas of photographs. Nine of the scorers usually overestimated spotted areas. Overestimation was greatest when infected area was smallest, often being two to three times the actual area, and it decreased as the infected area increased. When two leaves had equal total spotted areas, the leaf having substantially more (but smaller) spots was usually scored higher. Regression analysis showed that overestimation was inversely proportional to the natural logarithm of the disease area for all scorers and also directly proportional to the number of spots for five scorers. There were significant group, scorer within group, leaf, and scorer x leaf effects. If visual area assessments overestimate disease more seriously at low disease incidence, their use in equations for predicting disease increase or in equations for yield reduction will result in underestimation of the true rate or amount of loss. The coefficients of variation (x super(-) = 21.5%) indicated that visual estimates were not highly precise.

AN - 15546428; 419132 AB - Three crystalliferous (Cry super(+)) strains of B. thuringiensis) subsp. israelensis (serotype 14) that produce parasporal protein crystals toxic to dipteran larvae and several acrystalliferous (Cry super(-)) mutants, either induced or spontaneously derived from a single Cry super(+) parent, were examined for the presence of covalently closed circular (CCC) DNA in attempts to correlate toxin production with the presence of a specific plasmid. All of the Cry super(-) mutants derived from the Cry super(+) parental strain had lost a 4.0- to 4.4-megadalton (Mdal) plasmid. Bioassay data confirmed loss of toxin production by the Cry super(-). The plasmid patterns for several Cry super(-) derivatives differed in other respects from the pattern for their parent stain. The various Cry super(+) and Cry super(-) strains could be distinguished either by phenotypical differences in antibiotic sensitivity, crystal production, and toxicity, or by differences in their plasmid profiles.

AN - 15533463; 393159 AB - Variation in spore type and virulence of 218 isolates of Botryodiplodia hypodermia was examined. Seven percent of these isolates were considered to be atypical. Spores from atypical isolates were slightly narrower and longer than spores from typical isolates; however, the two types could not be differentiated by spore size. Approximately 50% of the spores from mature cirrhi of atypical isolates were septate; spores of typical isolates were aseptate. Atypical isolates were less virulent than typical isolates. Branches above the point of inoculation were killed on 20% of 132 branches inoculated with atypical isolates and on 73% of 266 branches inoculated with typical isolates. Atypical isolates should not be used in evaluating germ plasm.

AN - 14146706; 961942 AB - Evapotranspiration (ET) of a developing citrus grove in a humid climate in the Flatwood Land Resources Area was determined by water balance from measured rainfall, irrigation, subsurface drainage, surface runoff, and the change in soil moisture storage. Annual ET ranges from 820 to 1280 mm and averaged 1090 mm across all treatments. When soil moisture was not seriously limited the annual ET averaged 1210 mm. Linear regression of ET vs time indicated a significant increase of 13% in ET over the 8 years of the study. This increase was attributed to increasing tree size since the grass understory was maintained to provide similar cover conditions throughout the study. Daily ET rate, averaged by months, ranged from 1.5 mm in January to 5.0 mm in June. Four predictive equations for ET gave good estimates of measured values, but require crop coefficients that are slightly modified from previously published values. JF - TRANS. AM. SOC. AGRIC. ENG.

The required equations are presented following an analysis of the wind erosion equation literature which shows how the wind erosion equation literature which shows how the wind erosion equation was developed from short-term data. This analysis is based on viewing the soil loss as a time and space integration of a surface soil flux. The wind erosion equation is then partitioned into those parts that represent the short-term effects and the integration process. From this it is seen how one might ideally modify the wind erosion equation. The analyses point the way for future improvements in soil loss prediction equations. The results of the five 50-yr simulations are also presented. JF - TRANS. AM. SOC. AGRIC. ENG.

AN - 14037677; 868273 AB - Cellulolytic activity in 6 brown-rot fungi and 3 white-rot fungi was evaluated by their ability to release dyed breakdown products from dyed cellulose over an agar medium. Dyed-cellulose demonstrated cellulase activity in brown-rot fungi that the cellulose-clearing assay failed to detect. The dyed-cellulose assay must, however, be carefully monitored because the 3 white-rot fungi caused dyed-cellulose degradation products to disappear soon after maximum color development. The effect of pH and simple sugars on cellulase activity determined by the dyed-cellulose assay was similar to that found on cellulase activity in fungal culture filtrates. This cellulase-assay method should be a valuable research tool for study of chemical and culture effects on the enzymatic breakdown of cellulosic materials by wood-decay fungi. JF - MATER. ORG.

AN - 13923989; 778668 AB - A simple test is described for determining completeness of vegetable fermentations. Brines of fermented vegetables are adjusted to pH 4.5, inoculated with selected fermentative yeasts in culture tubes, overlaid with petrolatum, and incubated. Fermentation is indicated by separation of petrolatum from the brine due to gas production by the yeasts. Nutrient supplementation of fermented vegetable brines required to support gas production by yeasts and growth of lactic acid bacteria was determined. Absence of fermentable carbohydrate was the indicated reason for brines not being susceptible to secondary fermentation.

AN - 13903744; 757319 AB - Mannitol, in fermented green bean juice, was converted to lactic acid by Lactobacillus plantarum when the initial pH was raised to 3.9. However, at pH 3.5, mannitol was stable to anaerobic degradation by a 10 super(6) CFU/ml inoculum of 19 strains of L. plantarum) and four isolated homofermentative lactobacilli. Several strains were capable of limited mannitol degradation at an initial pH 3.7. Completely fermented beans were microbiologically stable for at least 6 months under anaerobic conditions at 27 degree C. It is possible that heterolactic acid-fermented vegetables are microbiologically stable provided fermentable sugars are removed and the pH is lowered below pH 3.7.

AN - 13879292; 731049 AB - Abundance, survival, and growth of mamane (Sophora chrysophylla ) regeneration were determined inside and outside sheep exclosures located in heavily browsed portions of the mamane forest of Mauna Kea, Hawaii. Mamane grew abundantly inside 16-year-old exclosures but was sparse outside. Height class distributions indicated that feral sheep prevented establishment of regeneration. Survival of seedlings and sprouts at 2-year-old exclosures was greater inside than outside. Rate of height growth for protected mamane reproduction was significantly affected by exclosure location. Cover data for prefered browse species other than mamane indicated that 3 endemic grases-Hawaiian bent (Agrostis sandwicense ), he'u-pueo (Trisetum glomeratum ), and Deschampsia australis , an endemic shrub-aheahea (Chenopodium oahuense ), and an introduced forb-gosmore (Hypochoeris radicata )-were susceptible to browsing.

AN - 13879204; 732253 AB - Prescribed burning was conducted in the spring and fall on mixed grass prairie vegetation to evaluate the effects of fire on silver sagebrush (Artemisia cana ). Climatic conditions and fuel loads at the time of burning were similar in both seasons. Spring burning under good soil moisture conditions resulted in low mortality of sagebrush and vigorous sprouting. Fall burning under dry conditions resulted in greater mortality and reduced shrub regrowth. Fire intensity in both spring and fall was directly related to mortality and inversely related to subsequent growth. As intensity increased, mortality became greater and regrowth became less. This range in response to fire indicates that burning can be used advantageously to manage plant communities containing silver sagebrush.

AN - 13858744; 712559 AB - Significant differences in plant resistance to larvae of the bluegrass billbug, Sphenophorus parvulus Gyllenhal (Coleoptera: Curculionidae), were found among and within range grass species and interspecific hybrids in nurseries at the Decker, Mont., surface mine and on a site near Miles City, Mont. Slender wheatgrass (Elymus trachycaulus ) and related species were particularly susceptible. Crested wheatgrass (Agropyron cristatum and A. desertorum ), thickspike wheatgrass (E. lanceolatus ), Russian wildrye (Psathyrostachys juncea ), and salina wildrye (Leymus salinae ) were among the species with a relatively high degree of resistance to the insect. Clonal lines of the Et. repens x Et. spicata hybrid differed significantly in resistance. Over 50% of the total phenotypic variation among the hybrid lines was attributed to genetic effects, indicating that selection for resistance would be effective. Documentation of genetic factors conditioning resistance to this potentially damaging insect pest would be a major contribution to the development of improved grass cultivars for revegetating disturbed and depleted rangeland.

AN - 13857531; 712700 AB - Ultracentrifugal analysis was used to study aggregation of 7S globulin induced by ultrasonic treatment of water extracts from defatted soybean flakes. In pH 7.6, 0.5 ionic strength buffer, aggregated 7S proteins sedimented as 40-50S species and represented 25-40% of the total proteins. Aggregates also existed at low ionic strength, but dialysis at 0.5 ionic strength caused additional aggregation of sonically modified 7S proteins. After exposure to 0.5 ionic strength, aggregates were stable to subsequent changes in ionic strength with one exception; some reversal of aggregation occurred when samples were dialyzed against water. Aggregates exhibited highest stability at pH 6.5-6.8 and were stable at room temperature for 9 hr or more. Sonic-induced aggregation of 7S proteins resembles the phenomenon observed on heating water extracts at 80 degree C.

AN - 13853413; 710829 AB - Analysis of proteins of the banana and citrus race of Radopholus similis was carried out by several different types of polyacrylamide gel electrophoresis. These included standard slab gel, SDS slab gel, gradient slab gel, and two-dimensional slab gel electrophoresis. A major band difference was detected between the two races by slab electrophoresis. However, several other poorly resolved but consistent bands of high molecular weight proteins near the gel origin also were considered as diagnostic. Resolution of protein bands was greatly improved by SDS and gradient slab gel electrophoresis, but no differences could be detected among the proteins resolved between the two races with these techniques. Two-dimensional gels revealed a large number of proteins, but background staining obscured them hindering interpretation. When nematode races were reared on three different host plants, no differences in protein patterns were detected between them, indicating host preferences does not play a role in determining the type proteins occurring in these nematodes.

All species responded to added fertility, but response to the 21-g fertilizer tablet was always greater than to any other treatment. Tablets made of sewage sludge also stimulated growth, and the 90-g sludge tablets stimulated growth comparable to that stimulated by the 9-g fertilizer tablets. High concentrations of foliar Mn. Cu, Sn, and Fe were found in all species. The nitrogen fixers, black locust and black alder, grew approximately three times faster than either sweetgum or sawtooth oak, and could be valuable for use in reforestation and rebuilding soil in the severely erodoed Copper Basin.

AN - 13848040; 710545 AB - Homoserine kinase is a potential control point in the biosynthetic pathway for threonine, isoleucine and methionine. The radish leaf enzyme was tested for the effects of end products on its activity. L-isoleucine, L-threonine, but not their D-isomers, and L-S-adenosylmethionine were effective inhibitors. At 0.1 mM, L-S-adenosylmethionine and L-isoleucine showed a marked synergistic inhibition. The combination of isoleucine, threonine, methionine and S-adenosylmethionine, at levels found in the radish leaf, inhibited homoserine kinase ca 25%. This fact, plus the stereospecificity of the inhibition suggested that the inhibition is involved in physiological control of threonine, isoleucine and methionine biosynthesis. Synergistic inhibition by compounds differing in charge and shape indicated that there is one major homoserine kinase with two allosteric sites.

Today, shrubby plants dominate the region. From 1880 to 1900, dramatic changes in the composition of vegetation took place along major waterways. Flooding and resulting channelization, plowing of the floodplains, and livestock grazing essentially eliminated the natural process of shallow groundwater recharge. Changes in vegetation on upland range between 1930 and 1980, were gradual but just as destructive. The authors documented the changes in the region's vegetation between 1880 and 1980, determined why the changes occurred, and determined if the range resource can be reclaimed.

AN - 13838014; 688046 AB - Over the past 10 years, a number of new initiatives to solve soil and water resource problems have been put forth. Early in the 1970s, policymakers were besieged by proposals to reduce water pollution from agricultural sources. A major issue throughout the period was how best to encourage farmers to practice more soil conservation. More recently, the emphasis has focused on shifting federal assistance from soil erosion control activities on land with low returns per dollar spent to more erosive land, where a dollar buys more control of soil loss and greater protection of water resources. Now in place, as a result of the Resources Conservation Act program, is a commitment to target gradually up to 25 percent of the assistance provided under U.S. Department of Agriculture conservation programs to those areas with the most serious problems. Also, because of action taken by the Agricultural Stabilization and Conservation Service in administering the Agricultural Conservation Program, there is a variable cost-sharing program used voluntarily in a number of counties. Both targeting and variable cost-sharing aim to strengthen local organizations dispersing cost-sharing funds to owners of erosive land. These two approaches may complement each other. But it is appropriate to compare these alternatives because their cost or public acceptability will likely vary.

AN - 13834203; 688052 AB - Terraces are among the oldest and most common soil erosion control practices. Despite the many criticisms of terraces - they cost too much, they are too hard to farm - farmers continue to build them. Why? Because terraces perform a function that no other conservation practice does: They intercept runoff before it becomes erosive and conduct it at a non-erosive velocity to a stable outlet. Terraces fill a niche in cropland conservatin systems that no other practice can by controlling sheet, rill, and gully erosion as well as channel erosion caused by concentrated flow on steeper, longer slopes. Effective soil erosion control requires vegetative, structural, and management practices combined in a soil and water conservation system. Vegetative practices are the first line of defense against erosion. Conservation tillage, for example, leaves protective residue on the soil surface. Its use is growing rapidly.

No mutants were found among 40,000 plants evaluated.

AN - 13832019; 688534 AB - Through both laboratory and field investigations, the authors sought to determine the relative rate of disappearance of degradation of permethrin in cotton plant residue as a function of plant residue distibution (incorporated, layered, surface-applied) in soil. Disappearance was fastest in the surface-applied plant residues, with only 11 percent cis- and 4 percent trans-permethrin remaining after 16 weeks under field conditions. The trans isomer was generally less persistent than the cis isomer. They demonstrated microbial involvement in permethrin degradation in the laboratory by using both KN sub(3)-amkended and autoclaved cotton litter-soil systems. In terms of permethrin disappearance and residue decomposition, the practice of leaving the permethrin-laden plant residue on the soil surface for several months after cotton harvest would appear to be better than th traditional practice of residue incorporation by disking.

Infiltration rates, sediment discharge, turbidity of runoff water, and seasonal erosion were measured. The results showed that residue in irrigation furrows controls erosion and reduces turbidity of runoff water. Because relatively small amounts of residue effectively reduced erosion, limited tillage can be used to prepare a seedbed and incorporate herbicides. Sufficient residue will remain to control erosion. JF - Journal of Soil and Water Conservation AU - Miller, DE AU - Aarstad, J S AD - Irrig. Agric. Res. and Ext. Cent., Agric. Res.

A square, continuous channel which could be rotated was used to simulate fluvial transport and runoff stress. Sediment size distributions measured after stressing the sediment for 5 minutes at simulated flows of 0.14, 0.28 and 0.56 m per s were similar to reference samples. Only increasing the stress period to 60 minutes at the highest velocity caused a decrease in sediment size. After breakdown by rainfall, runoff stresses usually encountered in the field should cause little additional aggregate breakdown.

Compost source had no significant effect on transplant quality of muskmelon (Cucumis melo ) seedlings. Marketable yield of cabbage, tomato, or muskmelon was similar regardless of the media used to grow the transplants. The concentration of Zn, Cu, Mn, Ni, and Cd were significantly higher in transplants grown in HM media than in those grown in LM media. With the exception of Cd, metal levels in transplants grown in LM media were similar to those grown in P-V. Transplant media has little influence on the heavy-metal concentrations found in either foliar samples or the edible portions of the crops studied. Heavy-metal concentrations in foliar samples of all 3 crops were lower than those found in transplants. The lowest concentrations were found in tomato and muskmelon fruit, and in cabbage heads. The Cd concentrations in edible portions were very low regardless of the source of compost in the transplant media, indicating that sewage sludge composts, particularly those low in heavy metals, can be used safely in the growing media of vegetable transplants.

After the bacteriostatic activity was overcome, all four herbs strongly stimulated acid production. The relative inhibitory effect of the herbs toward both microorganisms was oregano >> rosemary = sage > thyme. L. plantarum was more resistant than P. acidilactici to toxic effect of the herbs. Organisms from cultures exhibiting delayed fermentation in the presence of sublethal concentrations of an herb, when subcultured into fresh media containing identical herb concentrations, initiated fermentation without delay, indicating development of resistance to the herb's effect. Moreover, bacteria which had acquired a resistance to one herb were also resistant to the other three herbs.

Since the total amount of NTHZ in whole raw bacon was higher than that found in fried bacon and its drippings combined, it was concluded that NTHZ was not formed during frying as is N-nitrosopyrrolidine. The presence of NTHZ in bacon appears to be associated with smokehouse processing. JF - Journal of Food Science AU - Pensabene, J W AU - Fiddler, W AD - USDA-ARS, Eastern Regional Res. Cent., 600 E.

Six years later, sprouts averaged 7,000 per acre, stocking was 76 percent, and mean height of the tallest stem was 8.1 feet. Although these numbers were adequate for restocking, the poor condition of most sprouts, resulting from cattle trampling and snow breakage, strongly threatens the successful replacement of sawlog-quality growing stock.

As the name indicates, epididymitis is an inflammation of the epididymal portion of the testicle. The disease can occur in the head, body or tail of one or both testicles. It can occur in several locations at once. Several bacterial microorganisms have been found to be causative agents for RE. Nonbrucellary organisms include Actinobacillus actinomycetemcomitans and Haemophilus agni . Brucella ovis (i.e., Ram Epididymitis Organism, REO) is by far the most important organism to consider.

AN - 13787617; 647703 AB - Early tissue damage following a teratogenic dose of arsenic to the dam was studied in mice with the objective of detecting the primary lesion associated with the development of exencephaly. Animals were killed 6 to 21 h after a single 45 mg/kg intraperitoneal injection of sodium arsenate on day 8 of pregnancy and neurulation-stage embryos were fixed for histological and ultrastructural examination. In the prospective hindbrain, the most consistent feature associated with arsenate treatment was the widely separated neural folds which were not positioned for closure. Intracytoplasmic inclusions, interpreted as necrotic debris, were most numerous in the apical portion of the neural folds, sometimes extending into the mesenchyme, but they were not extensive in most embryos. In the prospective forebrain, necrotic debris was found throughout the neuroepithelium, in contrast to the posterior portions of the developing brain.

AN - 13785786; 643765 AB - A high soluble salt content in processed oil shales or other mineral wastes can pose problems in vegetation establishment on disposal piles and in water quality of drainage from disposal sites. In this field study a fine-textured, saline, processed oil shale was leached or covered with 0.3 m of soil to facilitate vegetation establishment. Salt moved upward into the leached processed shale or into the soil cover during the growing season following vegetation establishment which was facilitated by spinkler irrigation. After five growing seasons under prevailing climatic conditions averaging 260 mm of precipitation per year the salts had moved downward and soluble salt concentrations in the leached processed shale and soil cover were comparable to the salt concentrations present immediately after these treatments were applied.

AN - 13778533; 636934 AB - The effects of superphosphate, applied as a liquid or a solid, on the transport of dissolved and particulate P in surface runoff from established pasture were evaluated using field plots and natural rainfall. An approximately 3-fold increase in the transport of both dissolved inorganic P and particulate P in surface runoff was measured in 14 weeks following fertilizer application in the solid form compared to the liquid application. In addition, the application of solid fertilizer P had a more sustained effect on the concentration of both dissolved and particulate P in surface runoff. The results are discussed in terms of the relative abilities of the applied fertilizers to move away from the zone of interaction between surface soil and runoff, their effect on the P enrichment of streams, and their agronomic effectiveness.

This study determined the intensity of bark stripping of mamane (Sophora chrysophylla ), a small endemic leguminous tree, by these animals and assessed the impact of their browsing on the size class structure of mamane stands. In all but one of the 4 areas sampled, a high proportion of mamane trees bore bark stripping wounds.

AN - 13776539; 639739 AB - Wild wintering mule deer (Odocoileus hemionus ) browsed on a uniform shrub garden near Helper, Utah. On this garden, 21 accessions from 5 Artemisia taxa were selected to test the relationship between deer preference for these accessions and the amount of monoterpenoids present in the accessions. Deer preferences were determined by measuring removal of current year's growth. Sample of current year's growth (leaves and stems with terminal buds) were collected at the time preference measurements were taken to determine monoteropenoid content. Deer use ranged from zero to 83% of the current year's growth. Total monoterpenoid content among accessions varied from 0.75 to 3.62% of dry matter. The monoterpenoid content of various accessions of Artemisia taxa was not significantly related to deer preference.

Trapping conducted during the fall and winter of 1982 and spring of 1983 in 3 isolated 50-55 ha experimental fields near Brownsville, TX, indicated that larger catches were always made in traps located at the north and west field boundaries regardless of the geographical and climatological characteristics and distribution of surrounding vegetation at each experimental site. Survival of trapped weevils was critical only during the fall test because of the larger numbers of weevils caught per trap/day and the high temperatures and relative humidity prevalent during this time of the year.

AN - 13774333; 636372 AB - The demand for more water is increasing throughout the country. Research on upland watersheds clearly demonstrates that water yield can be increased using forest and range management practices. Based on the experience of the past several decades and a review of six papers in a recent AWRA series on water yield augmentation through vegetation management, the following issues and concerns are discussed: predicting increased yields from large basins; economic evaluation of additional flows; court acceptance and need for system models; the legal question of ownership and transferability of increased yields; and management emphasis on private and federal lands. The immediate potential for water yield augmentation is on carefully selected watersheds that have the bio-physical potential to produce high value water under environmentally acceptable multiple use management. The authors predict water yield management on a broader scale will result from increased pressures to solve the legal and economic issues involved.

AN - 13773619; 627592 AB - A 2 x 2 factorial design with treatments of Aspergillus ochraceus aflatoxin and ochratoxin A was used to evaluate the individual and combined effects of these mycotoxins on bruising and bloody thigh syndrome in broiler chickens. Although frank hemorrhaging was not associated with this mycotoxin interaction, elevated prothrombin times and increased incidence and severity of thigh and breast bruises implicate these mycotoxins individually and in combination with increased susceptibility to bruising during live-haul and processing. Prothrombin times fully recovered in broilers receiving these treatments for only 3 weeks; however, susceptibility to bruising did not recover. The data also suggest that the effects of ochratoxin A are longer lasting than the effects of aflatoxin.

AN - 13773413; 636257 AB - The Sierra Nevada produces over 50 percent of California's water. Improvement of water yields from the Sierra Nevada through watershed management has long been suggested as a means of augmenting the state's water supply. Vegetation and snowpack management can increase runoff from small watersheds by reducing losses due to evapotranspiration, snow interception by canopy, and snow evaporation. As a rough forecast, water production from National Forest land in the Sierra Nevada can probably be increased by about 1 percent (0.6 cm) under intensive forest watershed management. Given the state of reservoir storage and water use in California, delaying streamflow is perhaps the greatest contribution watershed management can make to meeting future water demands.

AN - 13771625; 636240 AB - Generally high rainfall and extensive forests in the East combine to produce excellent potential for managing forests for increased water yield. Models are presented that allow prediction of streamflow increase from hardwood and pine forests on a year-by-year basis. They are being routinely applied in land management planning on National Forests in the Southeast. A recent, independent test indicates that cumulative water yield increases can be predicted within about 14 percent of the actual value. However, because of the diverse land ownership patterns and the economic objectives of owners, realizing the potential will be difficult at best. The opportunity for realizing the full potential appears greatest where the land is publicly owned, but demand for water in the East has not reached the point where need for water dictates management prescriptions.

AN - 13769585; 639563 AB - Amounts of nitrogen, phosphorus, and sediment were measured in runoff from grassland watersheds in the Blackland Prairies, High Plains, Reddish Prairies, and Rolling Red Plains land resource areas of Oklahoma, and Texas. Periods of study were 3 to 5 years and included treatments involving fertilization, cultivation, and burning. Overall nutrient concentrations generally ranged from 2 to 10 mg/l for nitrogen and 0.3 to 2 mg/l for phosphorus. In most cases, less than half the nutrients existed as soluble forms in the runoff water. Typically, annual sediment losses were less than 0.5 metric tons/ha. Corresponding losses for nitrogen and phosphorus were less than 5 and 2 kg/ha, respectively. With proper management, the likelihood of any adverse environmental effects due to nutrient and sediment discharge from Southern Plains grasslands appears slight.

AN - 13768208; 631072 AB - Filter feeding of larval Simulium fulvinotum Cerqueira and Mello was studied near Manaus, Brazil, using particulate fluorescent dye in small black water streams. Transit time of particles through the midgut was 29.2 min in one stream with a current velocity of ca. 1 m/sec and 0.37 mg/l seston, but was only 26.1 min in another stream with 1.5-2.0 m/sec velocity and 2.01 mg/l seston. Penultimate instars of S. fulvinotum held the cephalic fans open for an average of 3.3 min before they were closed for removal of particles. Food of larvae included a variety of algae, detritus, bacteria and insect parts. Methods for obtaining adequate nutrition in the habitats of S. fulvinotum are: less frequent cleaning of fans, an efficient filtering mechanism, and location of larvae in swift current. JF - QUAEST.

AN - 13759310; 617758 AB - Four legumes and 3 grasses in combination, and the 3 grasses alone were evaluated for forage yield and persistence for 9 years in north-central Colorado. Sicklepod milkvetch (Astragalus falcatus ), alfalfa (Medicago sativa ), sainfoin (Onobrychis viciifolia ) or crownvetch (Coronilla varia ) were planted in alternate rows with crested wheatgrass (Agropyron desertorum ), Russian wildrye (Elymus junceus ), or pubescent wheatgrass (A. trichophorum ). Crownvetch failed to become established. Sainfoin, a short-lived species under Colorado range conditions, was gone within 5 years. Alfalfa persisted 7 years; it was killed by a combination of drought and pocket gophers. Sicklepod milkvetch persisted for the entire period. This site was too dry for pubescent wheatgrass and its stand declined rapidly. Crested wheatgrass with sicklepod milkvetch or alfalfa, and Russian wildrye with alfalfa produced the highest total yields. All grass-legume mixtures involving crested wheatgrass and Russian wildrye produced significantly more forage than the grasses grown alone in 30 cm row spacing. Crude protein content was higher for grass-legume mixtures than for the grass alone. JF - Journal of Range Management AU - McGinnies, W J AU - Townsend, CE AD - USDA, ARS, Crops Res.

AN - 13759252; 617726 AB - This series of studies compare winterfat (Eurotia lanata ) establishment from whole fruits and seed. The studies have demonstrated that the long hairs of the fruit function as "anchors" which help the radicle of a germinant to penetrate and begin growth into the soil. Other factors associated with the fruit also aid plant establishment. These factors have to do with better positive geotropic response of the radicle and with seedling vigor as measured by radicle growth in the soil. For these reasons, seedling establishment is better when fruits are broadcast, rather than when threshed seed is broadcast or planted at a 0.64cm depth. Soaking fruits in water at 0 degree C for 48 hours significantly improved germination rate and percentage. Recommendations are made for field planting winterfat.

AN - 13758373; 617784 AB - On the Jornada Experimental Range in southern New Mexico, 2 belt transects, 30.5 cm in width and totalling 2,188 m in length, were established in 1935 on 2 areas where honey mesquite Prosopis glandulosa Torr.) was spreading into black grama (Bouteloua eriopoda ) Torr.) Torr.) grassland. Maps were made of the transects which portrayed the vegetation occurring in each of the 7,180 contiguous 0.09-m super(2) plots along the transect. The vegetation on the transects in 1980 was compared to that portrayed by the transect maps made in 1935. One transect had been read in 1950 and 1955. During the 45-year period mesquite attained complete dominance and many new mesquite dunes formed. Black grama had a relatively high frequency in 1935 but had completely disappeared by 1980, both on an area grazed by livestock and on an area protected from grazing. Mesa dropseed (Sporobolus flexuosus) (Thurb.) Rydb.), fluffgrass (Erioneuron pulchellum (H.B.K.) Tateoka) and broom snakeweed (Xanthocephalum sarothrae (Pursh) Shinners) increased in abundance, even during the drought period between 1950 and 1955. Only 25% of the perennial forb species encountered in 1935-55 were found in 1980.

AN - 13757387; 614333 AB - There is an urgent need to preserve crop plants through imporved methods of vegetative propagation. The practice of using tissue cultures for the propagation of plant lines has proven useful. There are problems with the maintenance of tissue cultures. These include the time commitment of skilled personnel for repeated transfers, the danger of contamination during each transfer operation which, unfortunately, can cause elimination of a line, and most serious of all, selective genetic changes in the culture that take place duirng repeated subculturing. Loss of morphogenic potential, and the other problems associated with tissue culturing, would be minimized by being able to freeze tissues of the desired lines in a living condiition at very cold temperatures such as in liquid nitrogen. Successful cryogenic methods for doing this are now being developed. The highly desirable idea of a cell repository or bank of many frozen lines of genetically identified plant cells is slowly becoming feasible. This paper details a protocol which makes use of a mixture of compounds whose combination gives a number of species of plant cultures excellent cryoprotection at -196 degree C while minimizing adverse effects.

The electronic capacitance herbage meter was tested for estimating streamside forage biomass and use by livestock, and it was found to be potentially accurate but not without difficulties. Agreement between herbage meter and visual estimates of vegetation use was generally good, but some divergent estimates indicated the need to evaluate the source of the problems to refine both techniques. The authors foresee great potential for the herbage meter with respect to increasing reliability and reducing cost in riparian-fishery habitat studies.

Major species present were Blue grama (Bouteloua gracilis ), western wheatgrass, (Agropyron smithii ) dryland sedges (Carex Sp.). Slim leaf goosefoot (Chenopodium leptophyllum ) and other annual and perennial forbs were also present. Total herbage production, crude protein content, mineral concentrations, species composition and water use data were collected. Total herbage yields and crude protein from all the fertilizer treatments were significantly greater as compared with the control. Nearly all of the variation in phosphorus (P), calcium (Ca), potassium (K), and magnesium (Mg) concentrations and species composition were associated with the seasonal distribution of precipitation (years) and not with N-fertilization treatments.

However, few attempts have been made to quantify germination of seeds from feces, despite the importance of this information for development of plant-disperser coevolutionary theory. Some potential dispersers of seeds destroy most of the seeds they eat whereas others enhance the germinability of at least some seed species. The purpose of the study reported here was to compare the germination of seeds retrieved from feces of black bears (Ursus americanus ) with germination of seeds of ripe, uneaten fruit from northeastern Minnesota.

AN - 13752078; 617439 AB - The seasonal change of dry matter (DM) yield, estimated in vivo dry matter digestibility (DMD), and crude protein content of the vegetative and floral tillers of Rosana western wheatgrass (Agropyron smithii ) and Londorm green needlegrass (Stipa viridula ) was determined on forage harvested April through October on 10 dates during 1973 and on 11 dates during 1974. Vegetative tillers on both grasses were comparable in seasonal DM yield, DMD, and crude protein for both years. Flora tillers of western wheatgrass produced only 20% as much forage as did floral tillers of green needlegrass; however, they contained on the average 2 and 4 percentage units more crude protein and DMD, respectively, than floral tillers of green needlegrass. On an average, floral tillers contained 4 and 8 percentage units less crude protein and DMD, respecvively, than companion vegetative tillers. When floral tillers are harvested before DMD decreases below 50%, they are most valuable for maintenance of mature animals. Preventing development of floral tillers would increase DMD but decrease DM yield. JF - Journal of Range Management AU - White, L M AD - USDA, Agric. Res. Serv., North. Plains Soil and Water Res.

AN - 13751740; 617715 AB - Basin wildrye (Elymus cinereus ) is potentially a very valuable forage species adapted to saline/alkaline range sites in the Great Basin. Poor seed fill and low germination have limited the usefulness of this species for range revegetation. The recently release cultivar "Magnar" tends to overcome these obstacles and offers a higher potential for use of basin wildrye on rangelands. In this study the authors compared the germination of "Magnar" and its sister selection accession P-15590 at 55 constant and alternating temperatures. The seeds of both selections are highly germinable with optimum regimes for temperatures centered around 20 degree C. "Magnar" seeds had 82% germination at moderate seedbed temperatures and 32, 28 and 37% germination at colder, warmer, or widely fluctuating seedbed temperatures, respectively. Germination of "Magnar" seeds was most rapid at what became optimum temperature regimes for germination. Germination was increasingly delayed at extremely warm, cold, or widely fluctuating temperatures. JF - Journal of Range Management AU - Evans, R A AU - Young, JA AD - USDA, Agric. Res.

AN - 13751220; 616724 AB - Ips paraconfusus and I. pini were forced to construct galleries and oviposit within a limited resource. Other sources of mortality were restricted and both attack density and number of females per male were maintained in single species and mixed species bolts to enhance competition. Interspecific competition effects were not greater than intraspecific effects if attack density and parent sex ratios were held lower than what is normally seen under natural conditions. However, interspecific competition had a much greater effect than intraspecific competition when natural conditions were approximated. These competition effects may have provided the ecological pressure to explain the evolution of mutually inhibitory pheromone communication between these sympatric species. JF - Z. ANGEW. ENTOMOL.

AN - 13746334; 616837 AB - The longevity and mating capacity of 2 types of hybrid male Boophilus ticks were studied on stanchioned bovine hosts. Type I males (B. microplus male x B. annulatus female) had a mean premating period of 2.5 (range 1-4) days, whereas the average premating period in Type II males (B. annulatus male x B. microplus female) was 3.2 (range 2-5) days. The mean longevity of Type I and Type II males was 32.4 (range 14-59) and 71.2 (range 19-93) days, respectively. Type I males mated an average of 6.3 (range 3-14) B. annulatus and 9.2 (range 4-14) B. microplus females. Type II males mated an average of 26.2 (range 13-34) B. annulatus and 19.1 (range 5-31) B. microplus females. The high number of sterile matings and longer survival time exhibited by Type II males indicated that they would be the better choice in a sterile release program. Unmated hybrid females fed to repletion, but engorgement period was 35 days and repletion weights were reduced, as were egg-mass weights and egg hatchability (10.01%). Therefore, parthenogenesis would pose no threat to a sterile program as an alternate mode of reproduction.

AN - 13745343; 616083 AB - The role of antigen concentration on the immunosuppressive effect of adrenocorticotropin (ACTH) was tested in 6-week-old White Rock chickens that were immunized i.v. with 1 ml of heat-treated S. pullorum at packed cell volume concentrations of .06 to .00015%. At 16 and 10 hr before the antigen (Ag) injection, the birds received either 4 IU multiplied by 100 g body wt super(-1) of ACTH i.m., or the gelatin (Gel) vehicle. Total, 2-mercaptoethanol sensitive (2-ME sub(S)), and 2-mercaptoethanol resistant (2-ME sub(R)) agglutinin antibody titers were determined. The ACTH significantly suppressed total agglutinin titers with the lower Ag concentrations (.0015 and .00015%) but not with the higher Ag concentrations. The ACTH significantly suppressed 2-ME sub(S) titers only when Ag concentrations were low but suppressed 2-ME sub(R) titers regardless of Ag concentration. The results indicated that there may be critical Ag concentrations capable of inducing maximal humoral antibody responses in moderate environments but which allow these responses to be suppressed by environments that stimulate increased pituitary-adrenal activity.

AN - 13743618; 614040 AB - Bacillus sphaericus and Bacillus thuringiensis (H-14) were tested for larvicidal activity against Toxorhynchites spp. under laboratory conditions. In the presence of Aedes aegypti larvae, 24- and 48-h-old Tx. rutilus rutilus responded with 48 to 97% and 37 to 76% mortality, respectively, when exposed to 0.1 to 1.0 mg/litre of a lyophilized spore preparation of B. sphaericus (2013-4). T. theobaldi, Tx. amboinensis , and Tx. brevipalpis 48-h-old larvae were not significantly affected. A positive correlation between concentration of B. thuringiensis (H-14; IPS-78) and mortality was observed in 4th instars of Tx. amboinensis and Tx. brevipalpis in the presence of prey. No significant differences in mortality response were noted when Tx. amboinensis was exposed to 5 mg/litre of IPS-78 with 20 Cluex quinquefasciatus, Ae. aegypti , or Anopheles quadrimaculatus larvae present. The use of Toxorhynchites spp. and Bacillus pathogens in integrated vector control is discussed. JF - Journal of Medical Entomology AU - Lacey, LA AD - Insects Affecting Man & Animals Res.

AN - 13739739; 607166 AB - The microbiological quality of poultry meat patties as affected by the incorporation of 10% broiler giblets was evaluated. The major meat component was skinless broiler thigh meat. The average log sub(10) values of the total plate counts (TPC) of the ingredients were: thigh meat 7.0, hearts 4.0, livers 4.4, gizzards, 4.7, and emulsion 5.4. The initial TPC of the four patty products was approximately log 7.0 and patties spoiled in 2 to 4 days at 2 C. Coliform counts were greater than log 3.4/g in both ingredients and products, whereas the average E. coli, S. aureus , and KF streptococcal counts were log 1.6, 1.5, and 2.4 in the ingredients and 1.3, 1.8, and 2.9 in the products. Salmonella was isolated from all ingredients except skinless thigh meat and from 75% of all four patty products before, during, and after storage at -10 degree C. Escherichia coli and S. aureus were not detected in any of the patty products after 30 days at -10 degree C.

A comparison was made of the data from this survey and one conducted in 1969. The 1979 survey found that the chickens did not have a statistically significant reduced incidence of Salmonella compared to chickens analyzed in 1969. Also, much of the bacterial contamination on a carcass at the end of the evisceration line was transient and was readily removed by the fine spray washer. The addition of chlorine to chiller water did not appear to have an unusually beneficial effect on the chickens.

Fourteen centers had no dead or wilting trees. Ten centers had wilting trees and 27 had dead or dying trees within 15.2 m of the tree that died first on the site. Neither cacodylic acid injections nor deep girdling in 1970-1973 affected the subsequent incidence of mortality compared with no treatment. The average rate of increase in the 27 centers showing symptoms of oak wilt was 0.39 newly diseased trees per center per year. Total basal area per hectare was affected little by oak wilt.

AN - 13734109; 609439 AB - In a 4-yr field study at Salisbury, MD, an integrated control approach with cultural and chemical components successfully reduced snap bean diseases caused by the soilborne plant pathogens Pythium spp. and Rhizoctonia solani . The major control component was plowing infested soil to a depth of 20-25 cm rather than disking to 5-7 cm before planting. Pod weights were increased 43-100% in each of 4 yr in the plowed soil. Chemical seed treatment with metalaxyl or metalaxyl plus chloroneb also increased plant stand and weight, but the magnitude of the increase was not as great as that achieved with plowing. In 3 of 4 yr, plowing in association with seed treatment gave a greater yield than that attained when each component was used individually. Preparations of fungal and bacterial biological control agents added in-furrow or to seed were ineffective in reducing disease when used individually or in combination with cultural or chemical methods. The inoculum densities of Pythium spp. and R. solani were less in plowed soils than in disked soils.

Oat stem rust was retarded by poor conditions for infection during the early part of the growing season in the principal oat-production area in the north central United States. The principal race of oat stem rust in Mexico and the United States was NA-27, virulent on host genes Pg-1, -2, -3, -4, and -8. The 15-TNM was the principal wheat stem rust race in the United States (virulent on Sr5, 7b, 8, 9d, 9e, 10, 11, 16, 17, 36, and Tmp). In Mexico, races 113-RKQ (virulent on Sr5, 6, 7b, 8, 9b, 9d, 15, 16, 17, and 36) and 151-QFB (virulent on Sr5, 8, 9a, 9d, 15, 16, and 17) were most frequent.

Severe virus infections were observed in accessions of Trifolium hybridum, T. pratense , and T. repensthat coincided with a higher proportion of multiple infections found in these species. T. ambiguum and T. medium were less affected and fewer multiple infections were detected. T. alpestre was intermediate in its response to virus infections in the field. All four viruses were detected in T. pratense and three (CYVV, WCMV, and RCVMV) in feral T. repens plants growing adjacent to cold frames and evaluation fields.

AN - 13729923; 598213 AB - Damping-off and root rot of peas, caused by Pythium ultimum and Fusarium solani f. sp. pisi , was studied in 1980 and 1981 at Prosser, WA. In both years, seeds of a cultivars highly susceptible to both pathogens (Dark Skin Perfection) and breeding lines resistant to both pathogens (792016, 792028, 80-1284) were treated with fungicides, spores of Trichoderma , or both. In soil with natural infestation of F. solani and P. ultimum , the resistant breeding lines outyielded the susceptible cultivar regardless of seed treatment in both years. In 1981, seeds treated with T. viride gave the highest plant stands and seed yields, with both susceptible and resistant pea lines, although results with captan or metalaxyl were not statistically different from seed yields obtained with T. viride. T. viride (T-1-R4) was detected in the rhizosphere of peas in bloom, resulting from planting seed coated with conidia. Seed rot and preemergence and postemergence damping-off were reduced by the various treatments, as evidenced by differences in plant stands. Root rot, caused primarily by F. solani f. sp. Pisi , was not controlled. JF - Plant Disease AU - Kraft, J M AU - Papavizas, G C AD - Veg.

Aphanomyces root rot of peas; Rhizoctonia root rot of bean, cotton, and radish, Sclerotinia drop of lettuce, Fusarium wilt of cucumber; and Phytophthora crown rot of pepper were significantly decreased by addition of 10% compost to soil. Other diseases, Pythium damping-off of pea and bean, Fusarium root rot of pea and Thielaviopsis root rot of bean and cotton were not affected or were increased by compost. Suppression of diseases caused by Pythium and Rhizoctonia spp. was enhanced by increasing the time between soil amendment and planting. Survival of S. minor, R. solani, and Pythiumspp. was not decreased by the compost, but the activity of these pathogens in soil may be affected by an increase in microbial activity stimulated by addition of compost to soil.

AN - 13714020; 584986 AB - Of 10 million hectares of cropland in the Southern High Plains, 4 million are irrigated. The area of irrigated land will diminish in the future because the underground water supply is being depleted and fuel costs to pump water are increasing. As fuel costs rise, the profitability of irrigation can be maintained only by producing more crop per unit of water. Consequently, research at the U.S. Department of Agriculture's Conservation and Production Research Laboratory in Bushland, Texas, over the last 20 years has been directed toward improving productivity through improved irrigation water management, dryland water conservation, and limited tillage. This research has produced new insight into methods of combining limited irrigation, dryland farming, and limited tillage into profitable conservation farming systems for the 1980s.

Radiolabeled females deposited super(32)P into their eggs in sufficient quantities so that individual eggs were identifiable with a gas-flow proportional counter. The average radiolabeled egg contained about 0.4% of the radioactivity measured in the famale after oviposition. Females retained 65% of their radioactivity after 2 days of radioactive decay and oviposition of the first batch of eggs. They retained 34% of their radioactivity after 6 days of radioactive decay and the oviposition of 2 egg batches. The hatch was lower in eggs from the treated females. Eggs from the second oviposition had 59% of the radioactivity of eggs in the first oviposition. JF - MOSQ. NEWS. AU - Smittle, B J AU - Seawright, JA AD - Insects Affecting Man and Anim. Lab., Agric.

As RH decreased from near saturation to 40%, spore release was minimal, but further decreases stimulated considerable spore discharge. Sustained periods of constant RH 40 mu E multiplied by m super(-2) multiplied by sec super(-1)). Spore release was stimulated by short IR exposures ( similar to 2 min) and brief (2-min) RH changes. Spore release at low RH was increased slightly by vibration, created by dropping a 50-g weight 5 cm onto the specimen chamber, especially when specimens were exposed to IR.

Analyses of 4-year old trees growing in a single environment revealed high levels of additive genetic variance within populations. As a consequence, rather high estimates of genetic gains in growth potential were associated with weak selection intensities. However, genetic correlations were strong. Gains in growth potential were associated with delayed bud set and increased susceptibility to early fall frosts. JF - Silvae Genetica AU - Rehfeldt, GE AD - Interm. Forest & Range Exp.

AN - 13697348; 567360 AB - Interest in biological control of plant pathogens has increased strikingly in the past decade. Wider use of biocontrol, however, has been delayed in part by uncertainty as to how studies can be initiated in this field, particularly methods for finding and testing potential antagonists. By briefly considering how successful biological control systems were discovered and by describing strategies that could be used for other disease situations, the efficiency of finding and exploiting biological control agents will be increased.

AN - 13694095; 573393 AB - The causes of mortality of immature stages of Osmia marginata a non-social megachilid bee that nests in pre-existing holes, were compared among different sized trap-nests at nine California desert sites. Females preferred to nest in burrows with widest diameter and deepest bore, although these nests were associated with higher levels of immature mortality due to developmental failure, predators and parasites. There were considerable intersite differences in the percent of offspring that survived and in the enemies that claimed them. It is hypothesized that populations of O. marginata , as well as of other species of nest-building aculeates, are patchily distributed because of occasional extinctions of localized demes caused by a temporary build-up of enemies. The sex ratio of O. marginata did not deviate significantly from the expected value of unity. The species is unusual in that there is only marginal sexual dimorphism and very little within-sex variation in size.

Races were determined by the reaction of corn inbreds, B37, B37Ht, B37Ht2, and Oh43Ht3 after inoculation with spore suspensions from infected tissue. Race 1 was virulent only on inbred B37, whereas race 2 was virulent on both B37 and B37Ht. None of the isolates were virulent on B37Ht2 or Oh43Ht3, therefore, race 3 was not identified. Race 2 was identified from NCLB tissue collected in Florida, Illinois, Indiana, Iowa, Pennsylvania, Minnesota, and New York. Race 2 was widespread in Illinois and Indiana.

AN - 13690963; 574016 AB - Seventeen of 123 adult Cylindrocopturus adspersus (sunflower stem weevil) collected from the internodes and roots of overwintered sunflower (Helianthus annuus ) plants, and four of 133 adult C. adspersus collected from growing sunflower plants in the field yielded Macrophomina phaseolina , the causal agent of charcoal rot, on PDA-SP medium. Seven of 168 adults carried sclerotia of M. phaseolina . This pathogen was isolated on PDA-SP medium from three oviposition sites of C. adspersus on two of 38 field-grown sunflower plants, but was not isolated from subterranean parts of the infected plants. Three of 45 sunflower plants fed on by adult C. adspersus showed brown external discoloration of stems and black sclerotia in the pith, typical symptoms of infection by M. phaseolina . Control plants did not exhibit symptoms of infection.

AN - 13683605; 566899 AB - Initial screening of 55 genotypes in 17 Oryza species and subsequent reevaluation of the 24 most resistant entries revealed that several species were significantly more resistant to stem rot than cultivated rice, O. sativa . Averaged over both experiments, 15 genotypes representing nine species were more stem rot-resistant than Colusa, the most resistant cultivar in California. In a test conducted on eight of the more resistant entries, the presence or absence of flowering had no overall effect on stem rot development. The best stem rot resistance was found in species with genomes different from cultivated rice; however, stem rot-resistant entries of three species, O. rufipogon, O. nivara , and O. spontanea , which carry the same genome as cultivated rice, were identified. These entries are expected to be useful donor parents for the interspecific transfer of stem rot resistance to cultivated rice.

AN - 13680360; 566702 AB - In the laboratory, metham applied to soil columns as a drench killed 50% of the sclerotia of Sclerotium cepivorum at 16-17 mu g/ml and 95% of the sclerotia at 50 mu g/ml. Maximum kill of sclerotia by metham was obtained from 12 to 24 hr after application. Soil pH had little effect on the efficacy of metham, but at low soil temperature (5 degree C), more time was required to kill sclerotia. In soil columns, only 55% of the slcerotia were killed in the top 2 cm of soil, whereas at greater depths, nearly 100% of the sclerotia were killed. High concentrations of metham applied to soil columns were made ineffective by a subsequent drench of water. Metham applied through sprinkler irrigation at 234 L/ha with 2.5 cm of water provided 94% control of white rot on bunching onions and 30% control on leeks in field tests. The poor level of control on leeks may have been due to rain that fell on the field after metham application. JF - Plant Disease AU - Adams, P B AU - Johnston, SA AD - Soilborne Dis.

Metalaxyl and propamocarb hydrochloride seed treatments generally gave better protection than ethazol against Pythium blight. In liquid culture, metalaxyl had an ED sub(50) of < 1 mu g a.i./ml in inhibiting mycelial growth of the three Pythium species, with P. ultimum was most sensitive. Zoospore and oospore germination and sporangial formation were less sensitive to metalaxyl than mycelial growth.

Both summer and winter areas annually received 224 kg N/ha as NH sub(4)NO sub(3) fertilizer. Although seasonal N concentration and transport in runoff from the two areas were quite similar and did not significantly impair water quality, based on U.S. Public Health Standards. The subsurface flow provided the main pathway for N transport, with the surface transport being approximately 20 and 14% of the total N transport from the SG and WGF areas, respectively. The amount of sediment-N transported was very small because of low soil loss.

After 4 years, 44 of the original 75 snags remained. Species richness, bird abundance, bird species diversity, and equitability were all higher (P < 0.05) in plots with snags than in snagless plots. Cavity-nesting birds occurred on plots with snags but were virtually absent from snagless plots. Other species used snags for foraging and perching and were more abundant on plots with snags. Retention or creation of snags is recommended for bird management in clear-cuts. JF - Journal of Wildlife Management AU - Dickson, J G AU - Conner, R N AU - Williamson, J H AD - USDA For.

AN - 13675032; 551311 AB - Five small watersheds (0.25-3.1 ha) on sloping uplands in eastern Ohio were used to evaluate environmental effects of a beef management program of rotational summer grazing on one area, and rotational winter grazing/feeding with stored hay on another area. Surface runoff from watersheds with beef cattle management increased, compared with the long-term averages when hay was grown on the watersheds. Greater precipitation was the primary factor causing more runoff during the growing season (May-October), and the cattle management was a major contributing influence on the runoff increase during the dormant season (November-April). Maintenance of good vegetative cover on the study areas was a major factor in limiting annual average surface runoff to < 110 mm, which was a relatively small amount.

AN - 13674037; 547707 AB - To investigate the etiology of bacterial wetwood in elm (Ulmus americana ), the authors isolated microflora from wetwood capillary liquid, wetwood, and unaffected sapwood of branches, trunks, and roots. Stem and branch isolation samples were obtained from 52 elm trees, 35-85 cm in diameter at 1.3 m above mean ground level, and from the roots of 10 trees 42-78 cm in diameter at 1.3 stem height. Enrichment broth culturing for 48-96 hr under aerobic and anaerobic conditions, followed by repeated streaking on agar plates, was used to obtain pure cultures. Fourteen species of bacteria and two species of yeasts were isolated. Enterobacter and Klebsiella species were most often isolated from wetwood tissues. They occurred in greater numbers than Pseudomonas and Bacillus species which were most frequent in unaffected sapwood. The data show that an association of bacterial species produce the complex of symptoms observed. JF - Phytopathology AU - Murdoch, C W AU - Campana, R J AD - N.E.

AN - 13673747; 552119 AB - To evaluate soil erosion's seriousness requires knowledge about how much soil loss is occurring, given specific site conditions, and how much soil loss can be tolerated without damaging the resource. Considerable research has been done on methods to predict soil erosion, but limited research is available on which to base levels of soil loss that can be tolerated by various soils without damaging their productivity. To establish soil loss tolerances (T-values), therefore, assumptions had to be made. As a result, questions and controversies exist.

AN - 13673169; 551617 AB - A greenhouse experiment was conducted to determine if unleached volcanic ash from the 18 May 1980 eruption of Mount St. Helens would affect plant growth and uptake of N, P, K, Zn, and Cd. Swiss chard (Beta vulgaris cicla L.) and barley (Hordeum vulgare L.) were grown in Ritzville silt loam soil (mesic Calciorthidic Haploxerolls) amended with ash at rates of 0, 50, 100, 200, or 400 g kg super(-1), or with sand at the rate of 200 g kg super(-1). One-half of all soils received wheat straw (Triticum aestivum L.) to increase microbial activity. No adverse effects on either swiss chard or barley were found with ash amendments, with or without wheat straw additions. The addition of ash increased concentrations of Zn in swiss chard, but barley Zn concentrations were unchanged by ash amendments. The Cd concentration was below detectable limits in barley for all treatments and was decreased by ash amendments in swiss chard, with or without incorporated wheat straw.

AN - 13672755; 549766 AB - Auto-agglutinated and non-agglutinated cells of Campylobacter jejuni and C. coli were examined by transmission electronmicroscopy in phosphotungstate negative stain. Agglutination was induced by three factors (1) extracellular DNA, (2) an aggregated protein, probably a bacteriophage precursor, and (3) free phage-tail sheaths. Auto-agglutinated cells were often "leaky," with a mantle of adhering DNA. About 80% of the auto-agglutinated cells could be resuspended after treatment with DNAase. Flagella were loosely embedded in protein aggregates, especially in phage-infected cultures. They were clumped in a side-by-side arrangement by free phage-tail sheaths. These findings suggest that auto-agglutination could be minimised in suspensions of organisms intended for use in agglutination tests by harvesting early logarithmic-phase cells containing no more than a low phage population.

AN - 13671955; 555617 AB - For a risk recreation activity like whitewater boating, a manager's goal of providing for the health and safety of the visitor may conflict with the goal of providing the opportunity for a satisfying recreation experience. As whitewater river managers face the problem of safety and risks, they should consider what users think about safety programs. A test was made of the relation between views toward safety measures and the level of risk and thrills sought by floaters. Conclusions of the study are: (1) River floaters' views toward possible management safety measures are not related to the amount of risk they desire; and (2) floaters, in general, prefer some safety measures to others. If safety measures mean that managers will be more visible on the river, floaters tend to dislike them. JF - Water Resources Bulletin AU - Schomaker, J H AD - North Central For. Exper.

AN - 13670551; 547414 AB - Compatible hypovirulent (H) isolates of C. parasitica applied to either wounded or nonwounded chestnut blight cankers reduced dieback of American chestnut trees 27-51 mo after inoculation in comparison to dieback of wounded or nonwounded controls. Most control trees were killed back to the point of inoculation with virulent (V) isolates within 15-19 mo after inoculation. Initially, H treatments of wounded cankers promoted healing at the inoculation point, but subsequently the treatments sometimes failed to stop girdling by naturally developing basal cankers or secondary infections by C. parasitica at the inoculation point. Thirty-seven months after initial treatment, H isolates were recovered from a higher percentage of live treated trees than dead treated trees and were not recovered from dead control trees. In a second experiment, H isolates were recovered more frequently from nonwounded treated cankers than from wounded treated cankers. Secondary infection of cankers was demonstrated by recovery of V isolates of C. parasitica that differed from V isolates used for inoculum invegetative compatibility (v-c) and/or in conversion susceptibility.

AN - 13670498; 548282 AB - Decay of stems of d'Anjou pears by A. alternata is found in fruit treated with benomyl postharvest drench for control of Penicillium expansum and subsequently held in storage for prolonged periods. Benomyl favors the incidence of A. alternata , a slower growing and less competitive fungus than P. expansum , at the osmotic potential (-22 bars) and temperature (near 0 C) conditions of pears in storage. Prochloraz, chlorothalonil, iprodine, and triadimenol, in combination with benomyl, were effective in controlling Alternaria stem decay and blue mold on fruit treated and stored for 6 or 7 mo in cold storage. The most effective control of both Alternaria stem decay and blue mold was obtained with 1,000 mu g/ml prochloraz combined with 500 mu g/ml benomyl. Reduction of linear growth of A. alternata on potato-dextrose agar amended with prochloraz was not a useful method for determining the most effective concentration for disease control; 1 mu g/ml inhibited mycelial growth of Alternaria but 1,000 mu g/ml was required for disease control.

Aggressiveness is defined in this study as the relative rate at which a virulent isolate produces a given amount of disease. The Minnesota population was compared in the growth chamber with an asexual Texas population in an attempt to determine: whether sexual reproduction produces a greater range of genotypic or phenotypic variation for traits of aggressiveness than does asexual reproduction and whether sexual reproduction provides an adaptive advantage to the population by giving rise to some offspring with higher levels of aggressiveness than does asexual reproduction.

AN - 13662151; 543955 AB - T. r. rutilus is an autogenous species of mosquito whose larvae are predaceous on inhabitants of artificial and natural containers such as discarded tires and tree holes. After releases of 6-day-old, laboratory-reared adults into a substandard urban area of New Orleans, Louisiana, USA, little predator oviposition was observed in artificial containers breeding Aedes aegypti . The preference of this sylvan species for three holes for oviposition reduces its ability to locate artificial continers at ground level and therefore its usefulness for controlling urban container-breeding mosquitoes.

Range science is concerned with the plants, animals, soils, and waters on rangelands, particulary the interaction of these factors. Native plant communities should only be used as guides to determine site potential. Extensive practices on rangelands include manipulation of animals and burning. Intensive practices include control of unwanted plants, revegetation, and fertilization.

Ten to 15 percent of the land mass in the region produces the majority of the total flow. This paper addresses the opportunities for increasing flow through forest manipulation, and summarizes the research base that has yielded the current "state of the art" understanding of how snow pack and vegetation management can influence water yield. The optimal harvest design appears to consist of small openings, irregularly shaped, and about 3 to 8 tree heights in width parallel to the wind.

Although southern maize rust was severe in some years, correlations between favorable weather and disease appearance did not indicate that the pathogen had developed new forms that could infect corn during cool weather or overwinter in Indiana. Morphology and taxonomy indicate that P. sorghi should be considered the valid name for the common rust pathogen and P. maydis is a synonym.

AN - 13620019; 511711 AB - Western Washington and western Oregon comprise a water-rich region that has a very uneven annual distribution of both precipitation and streamflow. Highest demand for water coincides with lowest streamflow levels between July 1 and September 30 when less than 5 percent of annual water yield occurs. Increases in annual water yield in small, experimental watersheds in the region have ranged up to 600 mm after entire watersheds were logged and up to 300 mm in watersheds that were 25 to 30 percent logged. Most of the increase has occurred during the fall-winter rainy season, and yield increases in water yield from most large watersheds subject to sustained yield forest management are at best only 3-6 percent of unaugmented flows. Realistically, watersheds in this region will not be managed to produce more water. Water yield augmentation will continue to be only a small and variable by product of logging. The utility of water yield augmentation is limited by its size and by its occurrence relative to the time of water demand. In some local areas, reduction of fog interception and drip or establishment of riparin phreatophytic hardwoods may reduce summer flows. JF - Water Resources Bulletin AU - Harr, R D AD - USDA For.

AN - 13619938; 503913 AB - S. macrospora , long known as a minor pathogen of corn (Zea mays ) in the southern United States, traditionally has been considered a weaker pathogen in this country than the closely related and better known S. maydis . Recent studies in Latin America and Africa have indicated that S. macrospora can cause appreciable losses in yield, stored grain, and poultry fed on infected grain. Although S. maydis exhibits some competitive superiority with respect to metabolic and cultural characteristics, the authors' tests showed that S. macrospora is actually more aggressive than S. maydis in attacking young stalks and ears. The investigations indicate that the key to successful infection and disease development by S. macrospora is presence of inoculum under moderately humid conditions (mean RH = 50% day, 95% night) at typical U.S. Corn Belt temperatures.

AN - 13618884; 503302 AB - Field trials were conducted at four different dates in the winter early spring of 1979-1980 and also in 1981 in a commercial vineyard at Lawton, MI. In the 1979-1980 trials, a benomyl 50 WP spray of 4.8 g/L water (0.5 L per vine) gave significant control of ascospore infection by E. armeniacae when pruning wounds on 2-yr-old wood were inoculated either on the day of pruning and spraying or 14 days later. A lower rate of benomyl 50 WP, two rates of captafol 4F, and a biological control treatment of Fusarium lateritium gave little or no control. Pruning wounds declined in susceptibility over the 14-day period. No differences in susceptibility to infection were noted among the four dates of pruning. In the 1981 trial, benomyl 50 WP showed significant disease control at 1.2 and 9.6 g/L water compared with water-treated control vines.

AN - 13618556; 511683 AB - Increasing water for onsite and offsite uses can be a viable objective for management of certain western rangelands. One approach utilizes water harvesting techniques to increase surface runoff by preventing or slowing infiltration of rain. An attractive alternative, where applicable, is to replace vegetation that uses much water with plants that use less so that more water percolates through the soil to streams and ground water. Most sites are too dry to increase water yield in this way; probably less than 1 percent of the western rangelands can be managed for this purpose. However, where annual precipitation exceeds about 450 mm and deep-rooted shrubs can be replaced by shallow-rooted grasses, there is potential to increase streamflows and to improve forage for livestock. Little or no increase can be expected by eradication of low-density brush and pinyon-juniper woodlands. Potentials for improving water yield are reviewed and summarized by vegetation types.

AN - 13617240; 502778 AB - Burning when properly managed, is a practical tool in range management. Burning removes mature, unpalatable foliage and standing dead material and often increases herbage yields. Many workers have reported that new growth of both grasses and shrubs on burned ranges is higher in nutritive value than mature growth on nonburned areas. The objective of this study was to determine the effects of range burning on the nutritive contents of two south Texas forage grasses and one shrub. The grasses were buffelgrass (Cenchrus ciliaris ) and four-flowered trichloris (Trichloris pluriflora ); lime pricklyash (Zanthoxylum fagara ) was the shrub species.

AN - 13616777; 502769 AB - Soil levels were marked on grid and transect stakes in mesquite duneland and grassland areas at 3 sites on the Jornada Experimental Range in 1933 and 1935. Soil levels on one set of transect stakes were remeasured in 1950 and 1955. Remeasurement of soil levels at both transect and grid stakes in 1980 revealed that extensive soil movement had occurred during the intervening years. On a 259-ha site containing large mesquite dunes in 1935, maximum deposition and deflation was 86.9 and 64.6 cm, respectively, in l980. There was a net gain of 1.9 cm in soil depth over the entire area. On a 259-ha site only partially occupied by mesquite dunes in 1933, there was a net loss of 4.6 cm in soil depth and mesquite dunes had completely occupied the site by 1980.

P. bethelii , however, differs in its smaller, less-pyriform aeciospores, apparent lack of spermagonia, later aecial sporulation period, and constant association with dwarf mistletoe. Attempts to infect mistletoe-infected pines were either unsuccessful or inconclusive and potential alternate hosts have not been found. Field evidence suggests the rust may be autoecious.

A microencapsulated formulation of methyl parathion (Penncap-M)) was used for the first 2 applications and an emulsifiable concentrate formulation for the third. Colonies of honey bees, Apis mellifera L., exposed to the EC methyl parathion had ca. a 100 x increase in dead bees compared to prespray counts in dead bee traps the first day after the spray was applied. In the 2 Penncap-M tests, the increase in dead bees the first day after the spray was applied was ca. 10X. Analyses of different components inside the colonies indicated that significant residues of methyl parathion were found in the stored pollen while little or none was found in the brood, empty comb, or honey.

AN - 13612253; 502928 AB - A study of ways to increase winter use by elk (Cervus elaphus nelsoni ) of Pacific bunchgrass foothill range in southeastern Washington employed fertilizing and rangeland burning, with and without spring cattle grazing. First-year response of elk to fertilizer applied in fall (56 kg N/ha) was a 49% increase in use; however, no significant carry-over effect was noted in subsequent years. Fall burning to remove dead standing litter and enhance forage palatability provided no increase in elk use in winter. Intensive cattle grazing in spring to promote regrowth did not increase elk use. In fact, cattle grazing decreased winter elk use by 28% in 1 of the 3 years studied. The cost effectiveness of increasing elk use by fertilizing appeared marginal except perhaps in special situations.

AN - 13609936; 502909 AB - Prescribed burning was conducted in the fall and spring to evaluate the effects of fire on productivity of 3 forage species. Yield measurements were obtained throughout the growing season at biweekly intervals on western wheatgrass, blue gramma, and thread-leaf sedge. Supplementary measurements were made on vegetation cover and soil moisture. Herbage yield depended upon individual species, sampling date, and treatment. Spring burning of western wheatgrass and blue grama stimulated production by mid- and late-June, whereas fall burning also stimulated productivity but to a lesser degree. Fire can be used as a management practice to increase forage yield in the Northern Great Plains, but timing of utilization by livestock must receive careful consideration to assure maximum benefit.

AN - 13608617; 501848 AB - Diatoms are significant contributors to the primary production of farm pond ecosystems. They are also early colonizers and consequently affect the subsequent biological development of the system. Previous studies have described the relationships between diatoms and water quality (Ohl, 1965); interactions among planktonic, epiphytic, and epipelic diatoms (Clark and Runnels, 1975); or compared diatoms of farm ponds with experimental ponds (Troeger, 1978), but few studies have dealt with colonization of diatoms in new farm ponds. The objective of this study was to determine how the existing benthic diatom community in a creek might determine the community development in a pond resulting from the impoundment of the creek.

Disease progression was arrested in the first node below the inoculation point where the fungus was contained in cortical tissue surrounded by stem and lateral bud tracheids. Virginia and slash pines had a higher percentage of resin ducts forming tylosoids than loblolly and pond pines. More layers of regenerative parenchyma were observed in the xylem in inactive lesions of loblolly and pond pines than in Virginia and slash pines. Lignification of pith cell walls was observed in all species, but was more prevalent in inactive lesions in loblolly and pond pines. Primordial sporodochia were observed in Virginia pine in axils and sheaths of buds emerging directly below a dead shoot. JF - Phytopathology AU - Barrows-Broaddus, J AU - Dwinell, L D AD - USDA For.

AN - 13599270; 484785 AB - Respiratory activity of intact, attached roots was measured under field and controlled conditions. Root respiration of Yucca elata Engelm was highly temperature dependent: Q sub(10) values decreased from 2.1 (12-22 degree C) to 1.7 (26-36 degree C) as temperatures increased. Respiration ceased after 5 h at 42 degree C. In the field, in August, when net leaf photosynthesis was severely depressed, the diel fluctuation in the respiration rate of suberized and partially suberized roots was predominantly a function of temperature. Although small diel fluctuations in leaf acidity occurred in both field and greenhouse-grown plants, results of this study suggest that Y. elata is a C sub(3) plant.

AN - 13598077; 483594 AB - A system for employing open-ended root chambers to measure in situ acetylene reduction rates under field conditions is described. Gas mixtures containing about 2 mbar acetylene were continuously flowed through the chambers providing a continuous record of acetylene reduction. These chambers have been used to measure acetylene reduction rates of soybeans during three growing seasons. The system has proved to be reliable with a high degree of precision. The large amount of plant-to-plant variability observed in N sub(2) fixation research has been confirmed by the data collected with this system. However, such variability in physiological studies can be reduced by using a non-destructive system to compare the response of an individual plant with its rates before treatment.

AN - 13590780; 480646 AB - Several bean (Phaseolus vulgaris ) cultivars considered to be resistant to indigenous strains of bean common mosaic virus (BCMV) were attacked in varying degrees during a bean common mosaic epidemic throughout the northwestern United States in 1977. Using bean cultivars standard for differentiating BCMV strains, the authors identified the strains associated with these epidemics as members of strain groups II, III, and IV; one strain approximated strain group VII ( similar to VII). Two of these strain groups, III and similar to VII, were previously unknown in the United States. Strain group I (type strain) was isolated only from bean cultivars lacking any BCMV resistance. Only strain group V (NY-15 strain) was detected in Pinto UI 114 in the 1981 epidemic. Greenhouse isolates of each strain tended to be somewhat less virulent than the field cultures from which they originated. At least part of this difference appeared to result from a reduction in innate infective capacity of the virus during cultural substransfers. Three BCMV isolates were readily seed-transmitted in the most susceptible cultivars, but cultivar susceptibility to infection did not predetermine susceptibility to seed transmission of BCMV.

AN - 13582734; 475799 AB - Pecan nut clusters were inoculated with conidia of C. caryigenum on 10 dates ranging from 15 May to 11 September. Comparison of disease increase models based on a logarithmic curve-fitting regression analysis indicated that the 10 epidemics resulting from inoculations could be classified into three groups: early, mid-, or late-season. The midseason group had the greatest rate of disease increase, which may correspond to greater midseason nut susceptibility. Early season disease initiation decreased nut size, weight, percent oil, moisture, and protein content. Mid-and late-season disease initiation did not adversely affect any of these quality parameters. This indicated that the major-effect of pecan scab on nut quality occurred prior to mid-June, the time of the initiation of shell (endocarp) differentiation.

AN - 13578520; 475757 AB - Differences in dilatory resistance (slower disease development) to race IG-1 of Pyricularia oryzae were detectable among closely related rice lines planted in three-row by 60-cm "miniplots" separated by two buffer rows of a resistant rice line. This technique has direct application in screening large numbers of breeding lines for dilatory resistance to rice blast. It requires only a few grams of seed, and miniplots can be planted in existing blast nursery beds designed for specific resistance screening. Southern rice lines with no major-gene resistance to race IG-1 of P. oryzae showed various degrees of dilatory resistance, and all of them were more resistant than two lines developed in blast-free California. Most of the newer rice cultivars carry major genes for resistance to race IG-1, but many have multiple sources of dilatory resistance in their recent ancestry.

AN - 13552553; 437147 AB - West Bitter Creek floodwater retarding structure site 3 in South Central Oklahoma was instrumented and records obtained and analyzed to obtain information concerning an impoundment water budget that is useful to landowners and designers of these impoundments. On-site loss of water from the impoundment was only 17 percent of the inflow during three years when the annual precipitation averaged 26 inches and the annual inflow averaged 1.4 inches. Runoff from an eroded area with no farm ponds was about 70 percent greater per unit area than from a portion of the watershed where 71 percent of the drainage area was controlled by farm ponds. SCS runoff curve numbers varied between 57 and 96 for the impoundment watershed with an inverse relation between precipitation amount and curve number apprently caused by partial area runoff from impervious and semi-impervious areas. A comparison of measured event runoff versus event runoff computed by the SCS curve numbers gave an r super(2) of only 0.44.

AN - 13549479; 440467 AB - Occurrence of the Sekiguchi lesion in rice is conditioned by a single recessive gene and can be induced either by infection with Bipolaris oryzae and Pyricularia oryzae , or by exposure to certain chemical agents. Rice plants with Sekiguchi lesions were found both as naturally occurring mutants and in X sub(2) populations from super(137)Cs-irradiated seed. The lesions first appear on leaves and sheaths as gray water-soaked spots that turn orangish brown and become zonate as they enlarge, coalesce, and finally occupy the entire plant. Histopathological observations suggest that the Sekiguchi lesion represents a flaw in the biological mechanisms that normally regulate the hypersensitive response of rice to invasion by potential pathogens.

Foliar application. AN - 13546586; 430216 AB - Twenty-one fungicide formulations were applied as fall or spring foliar sprays to the dwarf bunt-susceptible winter wheat (Triticum aestivum ) cultivar Wanser during the 7-yr period 1975-1981. Several contact-type fungicides, as well as some systemic compounds, controlled dwarf bunt when applied as fall sprays. It is suspected that most, but not all, of the control from fall applications of the systemic fungicides resulted from direct action against teliospores of Tilletia controversa at or near the soil surface. Etaconazole, significantly reduced infection in 3 of the 4 yr it was tested and provided the first indication that the dwarf bunt fungus can be eradicated once it has become established in the wheat plant.

AN - 13542695; 441613 AB - In order to choose among "best management practices," forest managers need to predict sediment yield to perennial streams following various forest land operations. The "universal soil loss equation" (USLE) is not directly applicable to forest operations because of the heterogeneous soil surface conditions left by harvesting, site preparation, and planting. A sediment hazard index is proposed, to be based on the amount of exposed mineral soil and its proximity to streams. The model offered includes rainfall erosivity, soil erodibility and average land slope, together with the index W. A paired watershed experiment in the central Georgia Piedmont was used to estimate parameters in the model. The experimental basin (80 acres) was clearcut, drum roller chopped twice, and planted by machine. The standard error of estimate of sediment yield was computed to be about 50/lbs/ac per sampling period (four months). Use of William's erosivity index (storm flow times peak flow) reduced the standard error to 33/lbs/ac. JF - Water Resources Bulletin AU - Burns, R G AU - Hewlett, J D AD - U.S.D.A. For. Serv.

AN - 13542176; 438359 AB - Engorged larvae and nymphs (mixed sexes), and adult females of the lone star tick, Amblyomma americanum (L.), held in an outside insectary during 1980 were more affected (12-100% reduction in molting and 15-18% fewer eggs produced) by high average temperatures (30-31 degree C) and low average humidities (63-70% RH) in July and August than by more moderate conditions in April to June. The order of decreasing susceptibility to high and low temperatures and low humidities was: eggs > engorged larvae > engorged nymphs > engorged adult females. That smaller life stages of ticks have a greater surface to volume ratio and less total moisture, may be critical factors for survival in the field. Estimates of average developmental times (days), based on the average total effective temperatures or thermal constants (= average temperature ( degree C) - developmental threshold temperature/day X developmental times (days)), were preoviposition period (207), egg incubation (779), larval molting (308), and nymphal molting (352). Greater effective temperatures (11-33%) were required by ticks fed in April. Ticks held under varying temperatures and humidities required 10-29% greater effective temperatures than ticks held under constant conditions.

Yield of inoculated Narragansett plants was less than that of uninoculated plants and did not increase in response to increased soil moisture. Severity of Fusarium wilt was not increased for either cultivar by increased soil moisture in greenhouse experiments. During the first 4 wk following inoculation in an outdoor experiment, the number of dead plants of Narragansett alfalfa was significantly larger in wet soil than in moist soil. However, by 8 wk, this difference was no longer observed. Although increased soil moisture may have an effect on the initial rate of Fusarium wilt development, no evidence was found that it altered the basic characterization of Moapa and Narragansett as cultivars resistant and susceptible, respectively, to Fusarium wilt.

AN - 13536508; 435815 AB - The CO sub(2) assimilation of primary foliage of red maple (Acer rubrum) L.) and red oak (Quercus rubra L.), and of regrowth foliage produced in response to simulated insect defoliation, was measured throughout the season by infrared gas analysis: parallel measurements of leaf conductance were obtained by ventilated diffusion porometry. The increased CO sub(2) assimilation of regrowth maple foliage and the increases in CO sub(2) assimilation of residual primary foliage after defoliation offer evidence that heretofore unanticipated physiological mechanisms may be important to perennial species coping with herbivory.

AN - 13534172; 433733 AB - The amount of Pseudomonas paucimobilis , bacterial biomass-C ( mu g g super(-1) soil) became twice as great in high as in low N treatments, and significantly decreased between 39.5 and 6.35 h for the high inoculum, high N level treatment due to decreasing cell size. By the end of the experiment the cumulative respired carbon was twice as great and more inorganic P was immobilized for high compared to low N treatments and all available NH super(+)d4-N was taken up by the final sample time. Soil ATP concentrations were twice as large in high N treatments but the turnover times were twice as long compared to low N systems. The yield coefficient (Y), calculated from respiration and biomass-C values, equalled 0.61 while substrate was pentiful. Nitrogen limitation did not alter the efficiency with which glucose was transformed into biomass, but rather controlled the total amount of glucose used and biomass produced.

Pathogenic interaction were classified as resistant, intermediate, or susceptible. The magnitude of pathogenic interaction within the intermediate class was relatively low and since no isolated was found virulent on the uniformly resistant cultivars, no attempt was made to classify pathogenicity patterns into defined physiologic races.

Fusarium solani and P. ultimum were isolated most frequently from decayed seeds, while fungi isolated occasionally were Mucor sp. and other Pythium spp. Seedling emergence of cream-colored PI 458870 was reduced from 86% in the uninfested control to 58, 24, and 2% in soil artificially infested with 5, 50 and 500 propagules per gram of soil (ppg) of P. ultimum , respectively. In soil artificially infested with P. ultimum , seeds treated with metalaxyl, captan, ethazol, ethazol + thiophanate, thiram, or fenaminosulf significantly increased emergence over the untreated control. Fenaminosulf (Dexon) delayed germination and stunted seedlings. Metalaxyl-treated seeds stored at 4 C for up to 464 days before planting were protected when planted in field soil heavily infested with P. ultimum .
