A large-molecular-weight, female-specific, pupal hemolymph protein (vitellogenin, Vg) had electrophoretic and immuno-staining properties similar to Vt. A slightly larger female-specific hemolymph protein (larval-Vt) was found in last-instar female gypsy moth larvae. Vt, pupal-Vg and larval-Vg were recognized on Western blots by a rabbit polyclonal antiserum made against L. dispar Vt. The apoprotein subunits of Vt were 180,000 (apo-Vt180), 165,000 (apo-Vt165), and 38,000 daltons (apo-Vt38). Apo-Vg of similar sizes as the apo-Vt (apo-Vg180, apo-Vg165, and apo-Vg38) were recognized in larval and pupal hemolymph by the anti-Vt antisera. Apo-Vg began to accumulate in the hemolymph of last-instar larvae after day 2 and were not detected by Coomassie-or immuno-staining prior to this time. This indicates that synthesis of Vg must be initiated sometime early in the last larval instar of female gypsy moths. Larval ovaries increased in weight throughout the last instar (from 0.29 +/- 0.12 mg/pair on day 1 to 3.23 +/- 0.48 mg/pair on day 10), although they did not synthesize or take up Apo-Vg prior to day 7. Vt begins to accumulate in pupal ovarian terminal follicles by day 3. The largest increases in protein content, yolk length and follicle length of the 5 terminal follicles in each ovariole occurred between days 5 and 6 post-pupal ecdysis. Pupal total ovarian weight also increased throughout development, showing a 35-fold increase between day 4 (13.7 +/- 1.8 mg/pair) and day 10 (467.3 +/- 59.0 mg/pair). The above results indicate that initiation of Vg synthesis and ovarian Vt uptake are temporally and developmentally separate events in the gypsy moth.

The present study was undertaken to determine the content of the major anthraquinone constituents of sicklepod seeds, as well as carbohydrate, fat, mineral, and amino acid (protein) content. Thin-layer chromatography, ultraviolet spectroscopy, and combined gas chromatography-mass spectrometry revealed the presence of known and unknown anthroquinone derivatives. Known compounds include chrysophanic acid, physcion, obtusofolin, emodin, questin, obtusin, chrysoobtusin, aurantioobtusin, and others. Rapid thin-layer chromatographic procedures were developed to screen sicklepod seeds for anthraquinone derivatives. These procedures also revealed the presence of beta-sitosterol and of flavonids, UV-quenching compounds, and fluorescent blue compounds of unknown structure. The described methodology should facilitate screening large numbers of samples both in the laboratory and under practical field conditions. The data provide a rational basis for relating seed composition to reported muscle-damaging and other toxicological effects of sicklepod, for assessing the significance of low levels of the seeds in diets of foot-producing animals and humans, and for setting grain standards.

For flavor evaluation, bland aseptically packaged single-strength orange juice samples were flavored with each of the essences and compared with each other and with similar samples flavored commercially with a blend containing orange oils. Samples with concentrated essence containing either 25% or 35% ethanol were preferred over samples with standard commercial essence (15% ethanol). Preferences were also found for samples flavored with aqueous essences containing 15%, 35% or 40% ethanol, when compared to samples containing flavor fractions with oils. An aroma panel determined a significant difference between a standard commercial essence and each of the concentrated essences. Significant quantitative differences were found for most of the constituents that are common to all essences when concentrated essences were compared to commercial essence. Sixteen components (including six acetals) were identified only in concentrated essences. 1,1-Diethoxypropane and 1,1-diethoxyheptane are reported as orange essence constituents for the first time.

Periodically, fruits were removed from both treatments, and weight loss was measured. Mesocarp tissue was analyzed for osmotic potential, relative water content, membrane leakage, concentration of acids, sugars, and free amino acids, and cell wall composition. Fruit stored at 62% rh lost weight more rapidly, had increased decline in relative water content and osmotic potential, and had increased membrane leakage relative to fruits stored at 93% rh. Fruits stored at 62% rh exhibited more senescence characteristics than fruits stored at 93% rh. Both treatments developed pillowy tissue disorder, but for the fruits stored at 62% rh, the disorder was more severe. Arabinose and galactose levels in cell walls decreased during storage. This research has shown that long-term storage of cucumber fruits prior to pickling would probably result in poor quality products.

These compounds are (2E,4E,6E,8E)-3,5,7-trimethyl-2,4,6,8-decatetraene, (2E4E6E8E)-3,5,7-trimethyl-2,4,6,8-undecatetraene, (2E4E6E8E)-7-ethyl-3,5-dimethyl-2,4,6,8-decatetraene, and (2E4E6E8E)-7-ethyl-3,5-dimethyl-2,4,6,8-undecatetraene. The general synthetic scheme starts with tiglic aldehyde, (E)-2-methyl-2-butenal, extends the carbon chain with two Wittig-Horner olefinations, and completes the chain with a Wittig reaction. Lithium aluminum hydride reductions and manganese dioxide partial oxidations are used to prepare the intermediates for the subsequent chain extensions. The incorporation of methyl or ethyl side chains is controlled by the choice of the Wittig-Horner reagent, triethyl 2-phosphonopropionate or triethyl 2-phosphonobutyrate, respectively. After distillation of the final products, the all-E 3,5,7-trimethyl tetraenes were produced in 83-84% purity and 40-42% overall yield and the all-E 7-ethyl-3,5-dimethyl tetraenes in 71-73% purity and 20-25% overall yield from tiglic aldehyde.

IR30) were grown in paddy culture in outdoor, naturally sunlit, controlled-environment, plant growth chambers at Gainesville, Florida, USA, in 1987. The rice plants were exposed throughout the season to subambient (160 and 250), ambient (330) or superambient (500, 660, 900 mu-mol CO2/mol air) CO2 concentrations. Total shoot biomass, root biomass, tillering, and final grain yield increased with increasing CO2 concentration, the greatest increase occurring between the 160 and 500 mu-mol CO2/mol air treatments. Early in the growing season, root:shoot biomass ratio increased with increasing CO2 concentration; although the ratio decreased during the growing season, net assimilation rate increased with increasing CO2 concentration and decreased during the growing season. Differences in biomass and lamina area among CO2 treatments were largely due to corresponding differences in tillering response. The number of panicles/plant was almost entirely responsible for differences in final grain yield among CO2 treatments. Doubling the CO2 concentration from 330 to 660 mu-mol CO2/mol air resulted in a 32% increase in grain yield. These results suggest that important changes in the growth and yield of rice may be expected in the future as the CO2 concentration of the earth's atmosphere continues to rise.

Groups generally can be assigned on the basis of most recent ancestors without record. When maternal effects to their progeny. If the vectors for additive direct and maternal effects do not include the same animals, numerator relationship matrices for direct and maternal effects and between direct and maternal effects are different. Even if they are the same, the Q-P transformation and Westell's rules do not lead to simplification for calculation of the coefficient matrix unless group assignment is the same for direct and maternal effects. This result can be achieved by including each female ancestor with offspring having records in both vectors and by assigning both of her parents to the same group she would have been assigned for a model including only direct effects. This strategy is equivalent to assigning group effects similarly for both direct and maternal effects and allows making use of the computational efficiency available from the Q-P transformation and Westell's rules, which are similar to Henderson's rules for calculating the inverse of the numerator relationship matrix.

They also have shown how to simplify the mixed-model equations when genetic group effects are included in the model with what has become known as the Q-P transformation. Westell has given rules for calculating the coefficients for the Q-P transformed equations that are associated with the inverse of the numerator relationship matrix and genetic group effects. Those rules can be extended to include maternal effects and genetic groups for maternal as well as direct effects. As with the rules of Quaas and Pollak for the equations for the reduced animal model, a similar set of rules can be obtained for the genetic groups model after the Q-P transformation. The rules are derived easily by examining the algebraic results of absorbing the direct and maternal breeding value equations for non-parents into the parent breeding value, group and fixed effects equations. These rules involve Westell's rules and the inverse elements of the genetic (co)variance matrix for direct and maternal additive genetic effects. The rules make calculation of breeding values for parents for models including direct and maternal genetic group effects nearly as easy as for models without genetic group effects. Back solution for direct and maternal breeding values of non-parents similarly is as simple as when genetic group effects are not in the model. C1 USDA,LINCOLN,NE 68583.

The alternatives discussed involve minor changes in computing strategies from strategies used with reduced animal models that predict breeding values for direct and maternal effects. The easiest alternative is to assign foster dams to groups by breed and time period and add equations for fixed effects of breed-period. Random and, assumed, independent effects of foster dams can be nested in breed-period groups. If foster dams do not repeat, then those effects can be absorbed into equations for other fixed effects, additive direct breeding value and breed-period effects by slightly modifying least squares contributions to coefficients of those equations. A third alternative for foster dams of the same breed is to add breeding values for foster dams for direct and maternal effects to solution vectors for breeding values. Equations are similar to those without foster dams, except that least squares contributions to coefficient matrix and right-hand sides are to equations for maternal breeding values and nongenetic maternal effects of foster dams rather than biological dams. Relationships and covariance between direct and maternal effects contribute mixed-model coefficients to direct and maternal breeding value equations of biological dams. This alternative basically requires only larger solution vectors for direct and maternal breeding values to accommodate foster dams that might not be included. The fourth alternative includes a vector of maternal breeding values for foster dams of each breed of foster dams and would require using rules of Westell to calculate coefficients due to relationships and fixed maternal genetic groups within each breed of foster dam. These alternatives do not require much additional computational effort compared with full or reduced animal model equations when the transformation to predict breeding values is used with Westell's rules to calculate coefficients due to relationships and genetic group effects due to prior genetic selection.

Calves were weaned at 180 d and fed either 220 d in a feedlot (1977) or 170 d on forage and 140 d in a feedlot (1978 to 1980). Effects of parity, twinning and sex of calf were estimated as covariates within year-breed of dam. Pregancy at 45 to 60 d of gestation was 68% in heifers (H) and 74% in cows (C), with 40% single (S) and 60% twin (T) births. Dystocia was 28% in H vs 10% in C (P < .05), and tended to be less (P > .05) for T than S in H. More placentas were retained (P < .05) for T than for S in both H (35 vs 12%) and C (24 vs 4%). Twin gestations averaged 3 d shorter and subsequent calving intervals 13 d longer (P < .05), but total calf mortality was slightly higher (P > .05). Abortions were 4% in H only. Twinning females lost maternal weight during late gestation (P < .05) when crowding limited voluntary feed intake, while fetal requirements were 60% higher (P < .01). Twins increased milk output 25% (P < .05), but 11% higher feed intake maintained cow weight during lactation. Twinning reduced birth weight 13% and weaning weight 17% (P < .05), but 400-d feedlot weight only 9% because of compensating feedlot gain. Twins gained 18% faster than S during postweaning 170-d forage feeding, but 5% slower in feedlot to 8% lighter 490-d weight (P < .05). Assuming 40% higher veterinary and labor costs for twins, estimated integrated herd costs per unit of age-constant output value would be lower for T than for S production by about 24% for marketing either at weaning or at 400 d.

Calculations were done with correct data or data with 5, 10, 15 or 20% of the records per generation containing pedigree errors. Traits considered were litter size (LS), backfat (BF) and average daily gain (ADG). When data were correct, BLUP resulted in an advantage in expected genetic gain over SP of 22, 7.2 or 30.8% for LS, BF and ADG, respectively, and over SI of 9.6, 3.8 or 21.4%. When sire and dam pedigrees were incorrect for 20% of the pigs each generation, genetic gain using SI was reduced by 7, 2.5 or 6.5% and genetic gain using BLUP was reduced by 9.3, 3.2 or 12.4% for LS, BF and ADG, respectively. With 20% of the predigrees in error, the advantages in genetic gain of using BLUP over SP, the method unaffected by errors in pedigree, were 10.5, 3.8 and 14.6% for LS, BF and ADG, respectively. The results suggest that, although BLUP is affected to a greater degree by pedigree errors than SP or SI, selection of swine using BLUP still would improve response to selection over the use of SP or SI.

Data collected from 27 crossbred cattle included longissimus pH, temperature, sarcomere length, total and percentage of soluble collagen, muscle-fiber type and area, cathepsin B and B + L activities, calcium-dependent protease (CDP)-I, -II and inhibitor activities, myofibril fragmentation indices (MFI), Warner-Bratzler shear (WBS) force, sensory-panel tenderness (SPT) ratings and carcass traits. Stepwise regression analyses were performed among breeds or pooled within breeds with WBS and SPT as dependent variables. When MFI were included in the analysis, MFI at d 7 explained 50% of the variation in WBS and SPT at d 14. An additional 19% of SPT was accounted for by the addition of CDP inhibitor d 1 activity and percentage-area of alpha-R fibers to the model. However, because variation in MFI was not significant within breed subclasses and MFI could be classified more as a dependent variable, it was removed from the model. This resulted in CDP inhibitor d 1 activity explaining 44% of the variation in WBS and SPT at d 14. Also, percentage-area of beta-R fibers, 6 h pH and cathepsin B + L d 14 activity appeared in the model. In addition, CDP inhibitor activity was the only variable to be significant within breed groups. These data suggest that d 7 MFI could be used as a single predictor of d 14 longissimus muscle tenderness; however, CDP inhibitor d 1 activity (a biological event) also may be useful in predicting tenderness.

The average preoperative BW of pigs was 44.7 kg for Trial 1 (three pigs) and 35.3 kg for Trial 2 (seven pigs). In Trial 1, net absorption of ammonia (NH3) and glucose into the portal vein was determined three times at weekly intervals. The net portal absorptions were derived by multiplying the portoarterial plasma concentration difference of NH3 and glucose by portal vein plasma flow rate estimated with the p-aminohippuric acid indicator-dilution technique. Differences in the net portal absorptions of NH3 and glucose among the three weekly measurements were small (P > .05). In Trial 2, the first sequence of net portal absorption measurements was conducted when pigs were fed the basal diet, and the second sequence of measurements was conducted after the pigs had been fed the diet supplemented with 55 ppm of carbadox for 7 d. Carbadox supplementation reduced (P < .05) plasma NH3 concentration in portal plasma during the 2.5-h to 5-h postprandial period and decreased (P < .05) net portal absorption of NH3 during the 2.5-h to 4-h postprandial period. Carbadox, however, did not affect (P > .05) net portal absorption of glucose. We suggest that carbadox suppresses the production of cell-toxic NH3 by intestinal microorganisms and, thus, reduces the injury and turnover of intestinal cells. This effect would lower the maintenance requirement of the intestine, and allow a greater portion of ingested nutrients to be absorbed and utilized for body growth.

Ten groups of six pigs starting at 30 kg were restrictively fed (approximately 80% of ad libitum) one of five diets containing 11, 15, 19, 23 or 27% protein. Diets contained skim milk (12%). Soybean meal diluted with cornstarch was used as the supplemental source of dietary protein. Diets were isocaloric (3.8 Mcal DE/kg) and all contained the same amount of lysine (18 to 20 g/kg). Thirty pigs were treated daily with rpST (100 mu-g/kg) by i.m. injection; the remaining pigs were treated with sterile diluent (control) for 42 d. Growth rate was greater in rpST-treated pigs at all levels of protein intake; however, the magnitude of the response to rpST treatment was lowest among pigs fed the diet containing 11% protein. Feed:gain ratio, backfat depth and carcass fat content were decreased in rpST-treated pigs compared to respective controls. Additionally, the concentration of carcass fat decreased concomitantly with an increase in dietary protein intake. Concentration of carcass protein increased linearly as dietary protein increased in control and rpST-treated pigs. In contrast, treatment with rpST was associated with an increased visceral mass; the concentration of protein and fat in the viscera was influenced by protein intake but not by rpST. These results, characterized by few treatment interactions, suggest that when energy intake is kept constant and appropriately fed pigs serve as controls, dietary protein and rpST influence growth and body composition by independent mechanisms. In addition, under conditions when lysine is not limiting, high-protein diets are not required to obtain growth stimulation with rpST.

Each trial was a replicated 4 x 4 Latin square with four pairs of steers per trial (BW:322 kg, Trial 1; 278 kg Trial 2) and a control and growth promoter steer in each pair. Steers were fed a pelleted 75% concentrate diet containing 16.7% (DM basis). Each period consisted of 1 wk of intake adapation, 5 wk of feeding and 1 wk in metabolism crates (2-d adjustment and 5-d collection). Steers were switched among DMI but not among promoter treatments. Intercept and slope, respectively, for the regression of BW gain (kg/d) on DMI (kg/d) were -.66 and .276 for control vs-.84 and .328 for DES steers and -.69 and .276 for control vs-.89 and .356 for SYN steers. Similar regression values for N balance (g/d) on DMI (kg/d) were-10.3 and 6.91 for control vs -17.2 and 9.10 for DES steers and-4.5 and 4.67 for control vs-7.6 and 5.85 for SYN steers. Across trials, slopes differed from zero (P < .01), and promoter slopes differed from controls for gain (P < .01) and N balance (P < .10). During an extra period at the end of each trial, all steers were fed the high intake level for 6 wk, followed by N balance determinations the last 3 d of a 7-d fast. Fasting N balance (g/d) was-34.7 vs -49.5 for control vs DES steers and -52.3 and -57.6 for control vs SYN steers, respectively. Averaged across trials, responses by control and promoter steers differed (P < .05). Data show a divergence of both gain and N balance for promoter compared to control steers as DMI increased from fasting to 7 kg DM/d. C1 USDA ARS,SUB TROP AGR RES STN,BROOKSVILLE,FL 34605.

Our objectives were to determine effects of intake level on digestibility of 12 grass hays, and to relate differences in intake and digestibility to proportions of leaf blade, leaf sheath and stem. In each of two periods, 24 wethers were offered one of 12 hays at three consecutive levels of feeding: (L1) ad libitum, allowing 15% refusal; (L2) restricted to 100% of hay consumed ad libitum by individual wether during L1; and (L3) 1.8% of BW on a DM basis. Hays offered included two sorghum-sudan, four barley, four oat and two pearl millet. Hays were similar in NDF concentration but differed in morphological composition. Organic matter intake averaged 1.99 +/- .04, 1.79 +/- .04 and 1.52 +/- .01% of BW for L1, L2 and L3, respectively. Organic matter digestibilities averaged 71.8 +/- .55, 72.4 +/- .60 and 72.3 +/- .65% for L1, L2 and L3, respectively. Intake SEM within hays were lower with restricted intakes (L3), whereas the opposite was observed for the SEM for digestibility. Forage morphological composition within feeding level influenced intake and digestibility by altering diet selection capabilities of wethers. Wethers did not consume equal NDF amounts, ranging from .95 to 1.47% of BW, because hays differed in morphological composition. Ash-free ADF and 72% sulfuric acid lignin were higher (P < .01) in stem than in blade or sheath. In vivo digestibilities measured under restricted feeding conditions were related more closely (P < .05) to in vitro estimates of digestibility than were digestibilities measured under ad libitum conditions (r = .72, .79 and .85 for L1, L2 and L3, respectively). This study demonstrates that variation in morphological characteristics of forages may account for part of the difference in voluntary intake of forages of similar chemical composition. New knowledge in this area will be valuable in developing improved forage quality prediction procedures. C1 USDA ARS,US DAIRY FORAGE RES CTR,1925 LINDEN DR W,MADISON,WI 53706.

Defensive compounds and cuticular hydrocarbons were identified by gas chromatography-mass spectrometry and quantified by gas chromatography using an internal standard for each caste and all colonies. These analyses show that although the cuticular hydrocarbons of R. santonensis in Europe and R. flavipes in Georgia are identical, their relative proportions are different. However, the defensive compounds synthesized by their soldiers are different. A strong chemical polymorphism between sympatric colonies of R. flavipes in the SW United States was detected in terms of both the hydrocarbons of the workers and soldiers and in the defensive secretions of the soldiers. The six defensive secretion phenotypes are based on the presence or absence of terpenes whereas the cuticular hydrocarbon phenotypes are based on significant differences in the proportions of the various components. A multivariate analysis (analysis of principal components) clearly permitted discrimination of four phenotypes (three in R. flavipes and one in R. santonensis) without intermediates. The hydrocarbons responsible for these variations were identified, and it was shown that the variations are neither seasonal nor geographic. The phenotypes of the cuticular hydrocarbons (workers and soldiers) and defensive compounds are linked in each colony, forming in three groups in R. flavipes Georgia, one subdivided into four subgroups according to the defensive secretion phenotypes. The role of these polymorphisms is discussed and ethological tests indicate that the chemical polymorphism do not determine aggressive behavior. The taxonomic significance of these results is considered and two hypothesis are formulated: (1) We only detected a strong genetic polymorphism in one unique species, and we believe that R. santonensis was introduced into Europe in the last century from one R. flavipes colony. (2) Chemical variability characterizes the sibling species that can be grouped into the same subspecies R. flavipes. Unknown mechanisms of reproductive isolation separate them.

Twenty-nine of 34 host-fungus associations produced one or more of the alkaloids, most frequently peramine or ergovaline. Three alkaloids (lolines, peramine, and ergovaline) were found in tall fescue and in perennial ryegrass infected with A. coenophialum, while peramine, lolitrem B, and ergovaline were present in perennial ryegrass and in tall fescue infected with A. coenophialum and A. lolii produced similar patterns of alkaloids regardless of the species or cultivar of grass they infected, isolates of E. typhina produced either no alkaloids or only one or two different alkaloids in the grasses tested. Aphid bioassays indicated that Rhopalosiphum padi and Schizaphis graminum did not survive on grasses containing loline alkaloids and that S. graminum did not survive on peramine-containing grasses.

The pedicel protein has an amino acid composition that is very rich in glycine, alanine, serine, and proline (67% of identified residues), similar to that of some insect silks. Solid-state [C-13]NMR indicated that the nest paper is composed predominantly of cellulose. Silk, spun by mature P. annularis larvae, was shown by [C-13]NMR and amino acid analysis to be a protein very high in serine and alanine (53%), but the amino acid composition is distinct from that of the pedicel protein.

Smith); armyworm, Pseudaletia unipuncta (Haworth); and the black cutworm, Agrotis ipsilon (Hufnagel) was evaluated. Baiting of individual traps with all possible combinations of the four species taken two at a time caused a reduction in the catches of at least one of any two species involved when compared to traps baited for only one species. These results demonstrated the species specificity of sex pheromones identified for these species. Although the effects were reduced in some cases, the interaction between species also was observed when adjacent traps were baited with the sex pheromone dispensers of the different species. These results indicate that the spacing between pheromone traps when more than one species are being trapped at the same site affects trap capture and should be evaluated further.

Compared to clean air, the sex pheromone of its host Heliothis zea (Boddie) increased wasp residence times, walking times, and path lengths on a platform and decreased walking velocity. If wasps were released on top of a glass rod above a platform, the odor caused the wasps to land shortly after takeoff. In addition, a clear dose effect with regard to total residence and walking times was found. These responses were not elicited by three dosages of the sex pheromone of Spodoptera frugiperda (J.E. Smith) or by a blend of saturated acetates. These results correspond with the observation that H. zea is a common field host of T. pretiosum, whereas eggs of S. frugiperda are rarely attacked by this parasitoid.

These colloidal casein complexes are the result of an ensemble of multiple competing equilibria, arising from 1-degrees, 2-degrees, 3-degrees, and 4-degrees interactions of the individual caseins with themselves and with milk salts. Our laboratory has studied the fundamental principles of casein structure by application of modern methods of protein chemistry. The dynamics and quatenary structure of this interacting system have been examined using small-angle x-ray scattering. These data are now correlated with information obtained from [H-2] nuclear magnetic resonance relaxation techniques, and with insights into the secondary structures of the caseins gained by Raman and Fourier-transform infrared spectroscopy. Results are interpreted in terms of a model where hydrophobically stabilized inhomogeneous submicelles are incorporated into the colloidal micelle while retaining most of their structural and dynamic properties.

Most 'chilling-stress' studies have dealt, not with photosynthetic seedlings, but rather with the effect of low, non-freezing temperatures ( < 10-degrees-C) upon germinating seeds and pre-emergent seedlings. A photosynthetic seedling growth system was used to monitor the effects of temperatures from 10 to 35-degrees-C upon the roots and aerial portions of chilling-sensitive cotton and relatively chilling-resistant sunflower oil-seedlings. Length measurements of cotton seedlings were too variable to be reliable indicators of temperature treatment effects, but root and shoot fresh weights could be used as non-destructive measurements of differences in root and shoot temperature responses in both cotton and sunflower seedlings. The fresh weights were indicative of the relative water status of seedling roots and shoots, including that of seedlings returned to 30-degrees-C after exposure to other temperatures. Growth of both cotton and sunflower seedlings was inhibited to some degree at non-optimal temperatures and the capacities of the roots and shoots to return to normal water status, as indicated by fresh weights and relative water contents, was correlated with sensitivity to suboptimal temperatures.

Growth of photosynthetic seedlings of oil-seed genera is also significantly affected by suboptimal temperatures. A photosynthetic seedling growth system used to demonstrate suboptimal temperature stress effects in cotton was modified to monitor the effects of temperatures from 10 to 35-degrees-C upon the roots and aerial portions of cucumber, cantaloupe, and watermelon seedlings. Non-destructive measurements of fresh weights and the relative water contents of the roots and shoots of seedlings grown at 30-degrees-C and at non-optimal temperatures, as well as chilled seedlings returned to 30-degrees-C for one day, indicated significant intra-generic differences in temperature sensitivity and relative root and shoot water status of both the chilled seedlings and those recovering from thermal stress. The capacity to return to normal water status and resume growth differed between and within species and was correlated with recommendations for chilling tolerance.

The objective of this investigation was to determine the long-term effects of different CO2 concentrations on carbohydrate status and partitioning in rice (Oryza sativa L. cv. IR-30). Rice plants were grown season-long in outdoor, naturally sunlit, environmentally controlled growth chambers with CO2 concentrations of 160, 250, 330, 500, 660, and 900 mu-mol CO2 mol-1 air. In leaf blades, the priority between the partitioning of carbon into storage carbohydrates or into export changed with development stage and CO2 concentration. During vegetative growth, leaf sucrose and starch concentrations increased with increasing CO2 concentration but tended to level off above 500 mu-mol mol-1 CO2. Similarly, photosynthesis also increased with CO2 concentrations up to 500 mu-mol mol-1 and then reached a plateau at higher concentrations. The ratio of starch to sucrose concentration was positively correlated with the CO2 concentration. At maturity, increasing CO2 concentration resulted in an increase in total non-structural carbohydrate (TNC) concentration in leaf blades, leaf sheaths and culms. Carbohydrates that were stored in vegetative plant parts before heading made a smaller contribution to grain dry weight at CO2 concentrations below 330 mu-mol mol-1 than for treatments at concentrations above ambient. Increasing CO2 concentration had no effect on the carbohydrate concentration in the grain at maturity. C1 UNIV FLORIDA,USDA ARS,GAINESVILLE,FL 32611.

Dayold chickens were fed diets containing either 12 or 20% crude protein until 14 d of age and then switched to the opposite diet until 28 d. In experiment 1, chickens were killed at 28 d, and in experiment 2, at intervals following the switch at 14 d. In vitro lipogenesis and lipolysis were determined. The hepatic enzymes isocitrate dehydrogenase, malic enzyme and fatty acid synthetase were determined during the 14 to 28 d of age growth period. Both in vitro lipogenesis and lipolysis were greater at 28 d when chickens were fed the 12% rather than the 20% protein diet. Neither 0 to 14 d of age dietary treatment influenced 28-d metabolic parameters. In contrast, the 12% protein diet during the first 14-d period depressed body weight (160 g vs. 320 g; p < 0.05) and weight gain during the 14 to 28 d of age period regardless of dietary crude protein levels (508 g vs. 626 g; p < 0.05). Lipogenesis and lipolysis were at their highest points 4 d following the dietary switch. Isoproterenol decreased in vitro lipogenesis 70% in all dietary treatment groups. Stimulated lipolysis was not affected by nutritional status and was twice the unstimulated rate. Both malic enzyme and fatty acid synthetase activities increased (p < 0.05) following the switch from the 20% to the 12% protein diet and decreased (p < 0.05) following the switch from the 20% to the 12% protein diet. This change also occurred within 4 d. It can be concluded from this study that most metabolic responses to severe dietary challenges occur within 1 to 3 d and that a steady state is reached within 4 d.

Cellular copper content and the activity of Cu, Zn superoxide dismutase were significantly lower in both resident and thioglycollate-elicited macrophages from -Cu rats than in cells from +Cu controls. Reduced cellular Cu status was associated with impaired respiratory burst as assessed by zymosan-induced chemiluminescent activity and superoxide anion (O2-) generation. Candidacidal activity of macrophages from -Cu rats was also reduced and was highly correlated with chemiluminescent activity and O2- generation. In contrast, phagocytosis of opsonized erythrocytes by peritoneal macrophages from -Cu rats was normal. Elicited peritoneal macrophages from marginally Cu-deficient rats also killed significantly fewer yeast cells than macrophages from +Cu rats. These results demonstrate that macrophage function is impaired by dietary Cu deficiency and that the candidacidal activity of these cells may provide a sensitive indicator of Cu status.

Cellular Cu concentration, activity of Cu, Zn superoxide dismutase (Cu, Zn-SOD), generation of superoxide anion (O2-) in response to opsonized zymosan and phorbol myristate acetate, and candidacidal activity in elicited neutrophils were all significantly decreased by dietary Cu deficiency. Furthermore, survivability of Candida albicans injected into the peritoneal cavity of Cu-deficient rats was greater than in controls. Phagocytic activity of neutrophils was independent of cellular Cu status. To determine whether the impaired function of neutrophils was also characteristic of marginal Cu deficiency, weaned rats were fed diets containing either 0.6, 1.1, 2.0, 2.7 or 6.7 (control) mg Cu/kg for 5 wk. The activity of Cu,Zn-SOD, phorbol myristate acetate-induced production of O2-, and candidacidal activity were significantly lower in neutrophils from rats fed diets with less-than-or-equal-to-2.7 mg Cu/kg compared to control cells. In contrast, decreased tissue Cu and the activity of erythrocyte Cu,Zn-SOD were observed only when dietary Cu was less-than-or-equal-to-2.0 mg/kg. Reduced SOD activity, respiratory burst and candidacidal activity of neutrophils were evident as soon as 1 wk after initiating the dietary treatment. Feeding +Cu diet to Cu-deficient rats for 1 wk restored Cu status and function of neutrophils to control levels. These results show that neutrophil function is reversibly impaired by marginal and severe Cu deficiency and suggest that the Cu status and function of these cells may provide a sensitive indicator for assessment of Cu status.

Two sequences, Bo6 and Bo25, had the highest sensitivity and further analysis revealed unique characteristics of each of these. Neither sequence hybridized detectably to bovine DNA. Bo6 detected 100 pg of both a Mexican and an Australian isolate of B. bovis, but Bo6 also detected 1.0 ng of Babesia bigemina DNA under identical conditions. A unique characteristic of Bo6 is that it hybridizes to an apparent 7.4-kilobase DNA in undigested genomic DNA of both B. bovis and B. bigemina. The sequence is well conserved between the 2 geographic isolates of B. bovis, but it is apparently divergent in B. bigemina. Bo25 did not hybridize detectably to bovine or B. bigemina DNA. This sequence detected 100 pg of homologous B. bovis Mexican isolate DNA, but the sensitivity was reduced to 1 ng for the Australian isolate DNA. The restriction enzyme profile of the Bo25 sequence in genomic DNA differed markedly in the number, size, and intensity of bands between the 2 B. bovis geographic isolates tested. Thus, the Bo25 sequence can distinguish geographic isolates of B. bovis. C1 USDA ARS,ANIM DIS RES UNIT,PULLMAN,WA 99164.

Vaccination of cattle with purified proteins of H. lineatum, particularly hypodermin A, is known to protect cattle against hypodermyiasis by this species. The development of a protective recombinant vaccine against both species using hypodermin A isolated from H. lineatum would require that immunological epitopes be shared by complementary proteins in H. bovis. The purpose of this study was to investigate the soluble proteins of H. bovis first-instars for shared epitopes with H. lineatum. Soluble H. lineatum and H. bovis first-instar larval proteins were resolved by nondenaturing polyacrylamide electrophoresis, blotted onto nitrocellulose paper, and probed with selected polyclonal cow, polyclonal rabbit, and mouse monoclonal antisera. Considerable cross-reactivity was demonstrated by antibodies in the serum of an H. lineatum-infested cow as 6 of 10 resolved H. bovis proteins were bound by the antibodies. The most common shared epitope(s) was associated with hypodermin C, a collagenolytic protease. Hypodermin A shared epitope(s) were noted on 1 prominent H. bovis band (HB1-2). Hypodermin B, a prominent protein in H. lineatum, did not appear to share epitopes with H. bovis proteins. Shared epitopes between H. bovis proteins and hypodermins A and C of H. lineatum would suggest that cross-protection of cattle against H. bovis can be expected by vaccination with recombinant proteins of H. lineatum.

None of the isolates produced fatal infections in the mouse strains tested. Parasitemias were quantified over 34 days and found to be similar in mouse strains infected with Tc-O and Tc-A. Parasitemias in Tc-D-infected mice were detectable only by blood culture. Pseudocyst numbers, inflammatory changes, and weight changes were quantified in CFl mice infected with the 3 isolates. Tc-O- and Tc-A-infected CFl mice were shown to be myotropic and produced comparable weight increases, pseudocyst numbers, and inflammatory changes in similar tissues. Tissues found to contain pseudocysts were muscles of the bladder, abdominal wall, thigh, heart, and diaphragm. Clinical signs of infection, pseudocyst numbers, and inflammatory changes were minimal in Tc-D-infected CFl mice. Tissue tropism of this isolate was not determined. The in vivo infectivity characteristics of these isolates suggests that Tc-O and Tc-A are similar and differ markedly from Tc-D. C1 USDA,ANIM & PLANT HLTH INSPECT SERV,PLUM ISL,NY 11944.

For alterations of PFD, chemostat populations were expected to 50, 130 and 230-mu-mol photons.m-2.s-1 of photosynthetic active radiation (PAR). Decreases in biomass, cholorophyll a (Chl a) and c-phycocyanin (CPC) contents, and CPC:Chl a and CPC:carotenoid ratios coincided with increasing PFD. Total carotenoid content was not altered. Increases in the relative abundances of myxoxanthophyll and zeaxanthin and decreases in the relative abundances of echinenon and beta-carotene within the carotenoid pigments coincided with increasing PFD. Increases in Chl a-specific photosynthetic rates and maxima and decreases in biomass-specific photosynthetic rates and maxima with increasing PFD were attributed to increased light harvesting by carotenoids per unit Chl a and reduction in total pigment content, respectively. Responses to spectral quality were tested by exposing chemostat populations to a gradient of spectral transmissions of 50-mu-mol photons.m-2.s-1 PAR. Biomass differences among populations were likely attributable to the distinct absorption of the PAR spectrum by Chl a, CPC, and carotenoids. Although pigment contents were not altered by spectral quality, relative abundances of zeaxanthin and echinenone in the carotenoid pigments increased in populations exposed to high-wavelength PAR. The population adapted to green light possessed a greater photosynthetic maximum than populations adapted to other spectral qualities.

Fat-free mass (FFM) was estimated from TBI measurements using a previously determined multiple regression equation. No difference (p > 0.05) was found in mean FFM values by method of experimental condition. In the uncontrolled state, fat mass and percent body fat (%BF) by impedance were lower (p < 0.05) than that observed by HD or by TBI under controlled conditions. Linear regression analyses between FFM determined by HD and predicted by TBI under controlled and uncontrolled conditions yielded regression coefficients similar to the line of identify. The relationship between %BF by HD and calculated from impedance-predicted FFM and body mass under uncontrolled conditions was different (p < 0.05) from the line of identify. In contrast, the regression of densitometric against impedance-predicted %BF under controlled conditions was similar to the line of identify with an error of 2.8%. These findings indicate the need for controlled measurement conditions to obtain valid body composition estimates using the TBI method in healthy people.

In vivo assay with endogenous nitrate-N only as substrate best approximates nitrate assimilation. The necessity of analyzing numerous samples from multiple replications of field grown cotton prompted the development of a simple colorimetric determination of 0.1 M K-phosphate buffer at pH 7.5 with 5% propanol and 1% chloramphenicol. Cotton petioles were sampled early in the morning, incubated in the medium under air for 1 h at 27-degrees-C. After reaction stopage, the sample is retained in the incubation medium for 2 h. Ninety-eight percent of the nitrate-nitrogen (N) content in the petiole was found in the incubation medium, demonstrating that the method allows determination of the petiole nitrate-N content and its rate of redution.

The rate of uptake of salt by samples of cattlehide in saturated brine decreased as the temperature of the brine decreased. Continuous mechanical movement of the hide samples in brine increased the rate of salt uptake compared to static immersion. Data from salt-saturation measurements of more than 50,000 commercially processed hides were examined. It was found that more than 75% of the cattlehides cured during the winter months in the colder regions of the country had unsatisfactory levels of salt saturation.

There was a highly significant response of all species except Culex erraticus and Anopheles quadrimaculatus to CO2. Also, a significant negative octenol response was shown for An. quadrimaculatus. Coquillettidia perturbans, Mansonia titillans and Cx. salinarius had an increased response to octenol relative to no attractant. There was a slightly negative interactive effect between octenol and 500 cc/min CO2 for Anopheles spp. and Culex (Melanoconion) spp. Both Cq. perturbans and Ma. titillans showed a significant synergistic enhancement in catch with octenol supplemented CO2 when compared with CO2 alone. However, their response to CO2 was not significantly different at 2 release rates (200 and 500 cc/min). There was a slightly greater than additive effect for the combination of octenol and CO2 for Cx. nigripalpus. C1 USDA ARS,POLK COUNTY ENVIRONM SERV,GAINESVILLE,FL 32604.

Substrate degradation was noted in all systems, but occurred to a much greater extent in dispersions (approximately 90%) than in liposomes (0-25%). The difference in degree of degradation is attributed to dissimilarities in the microenvironment of 7-ketocholesterol in the two systems. The principal decomposition product was identified as 7-ketocholestanol, a compound that can arise from hydrogenation of the double bond of the starting material. Also detected, but in lower concentration, were the epimeric 7-hydroxycholesterols resulting from the reduction of the original carbonyl function. Both 7-ketocholestanol and the epimeric 7-hydroxycholesterols are believed to be secondary species generated by the interaction of the starting material with the primary radiolysis products of water. In addition, many minor degradation products were noted but not identified. C1 USDA ARS,EASTERN REG RES CTR,600 E MERMAID LANE,PHILADELPHIA,PA 19118.

Squalene, a highly unsaturated C30 isoprene hydrocarbon, was found to be present in the epicuticular wax of grapefruit. The optimal temperature for biosynthesis of squalene in grapefruit was 15-degrees-C; this is also the temperature reported previously as the optimum temperature for conditioning grapefruit against chilling injury. Control and temperature-conditioned grapefruit were stored monthly over three seasons from 1986 to 1989. Fruits were rated for chilling injury and the levels of squalene were determined. An inverse relationship found between CI and squalene level suggested that squalene may protect grapefruit from CI. RP NORDBY, HE (reprint author), USDA ARS,HORT RES LAB,ORLANDO,FL 32803, USA.

The purified enzyme is a microheterogeneous glycoprotein containing isozymes varying in molecular weight, pI and specificity. It consists of 64, 62 and 59 kDa species as determined by denaturing polyacrylamide gel electrophoresis. Five isozymes (pI 4.40, 4.47, 4.58, 4.67 and 4.72) are detected by isoelectric focusing using both silver and activity stains. Chromatofocusing was used to separate the isozymes according to pI. Although all the isozymes are specific for oleate vs stearate esters, one isozyme (pI 4.72) is also specific for oleate vs palmitate. The number of isozymes is reduced to two (pI 4.67 and 4.72) after carbohydrate removal using endoglycosidase F/N-glycosidase. These isozymes may be products of two lipase genes.

Concentrations from 1-100 p.p.m. triadimenol stimulated aflatoxin production. Maximum stimulation was about 25-fold in one isolate and 700-fold in the other. Triadimenol concentrations above 2.5 p.p.m. inhibited radial growth in both isolates, and inhibited sclerotium formation in the isolate that made sclerotia. Final pH of cultures increased with fungicide concentration. Changes in sclerotium and aflatoxin formation were correlated with, but not caused by, changes in pH. In vitro responses to triadimenol are evidence of a close relationship between sclerotium and aflatoxin production. Implications for use of triadimenol to control contamination of crops by A. flavus are discussed. RP BAYMAN, P (reprint author), USDA ARS,SO REG RES CTR,NEW ORLEANS,LA 70179, USA.

CO2 fixation showed a linear response with light intensity from zero to about 500-700 mu-E m-2 s-1. However, at light intensities of only 5-22 mu-E m-2 s-1, the energetic threshold for activation of the CF was found to be significantly lowered (as compared to the pre-dawn state), presumably through reduction of the regulatory sulfhdryl groups of the gamma-subunit of the CF. When these studies were extended to chamber-grown plants, it was found that as little as 5 seconds of illumination at 4 mu-E m-2 s-1 caused apparently full CF reduction. It is clear, therefore, that the catalytic activation of CF is not rate limiting to the induction of carbon assimilation under field conditions during a natural dark-to-light transition at sunrise. A model, based on the redox properties of the regulatory sulfhydryls, was developed to examine the significance of sulfhydryl midpoint potential in explaining the differences in light sensitivity and oxidation and reduction kinetics, between the CF and other thioredoxin-modulated chloroplast enzymes. Computer simulations of the light-induced regulation of three representative thioredoxin-modulated enzymes are presented. C1 UNIV ILLINOIS,DEPT PLANT BIOL,URBANA,IL 61801.

Rutgers) fruit. Activity was greatest if CBP was extracted from mature green tomatoes with jellied locules. CBP extracted from mature green tomatoes with immature seeds had no elicitor while CBP from turning or red ripe tomatoes was only moderately active. Infiltration of CBP from normal mature green fruit into ripening inhibitor (rin) mutant tomato fruit stimulated ethylene production and attenuated red pigmentation in these fruits. Partial purification of the active material was accomplished using DEAE-Sephadex and BioGel P-100 chromatography. The most highly purified fraction is comprised of neutral carbohydrate (95%) with a relatively low content of amino acids (< 1%) and a uronic acid content of less than 5%. This material may be an endogenous trigger of ethylene production and ripening. C1 USDA ARS,BELTSVILLE AGR RES CTR,HORT CROPS QUAL LAB,BELTSVILLE,MD 20705.

Compared to red light of the same fluence rate, blue light effects in maize were repressive for the accumulation of Chl a, b, carotenoids and light-harvesting complex-2 (LHC-2) proteins. The maximal reduction of proteins bound to the light-harvesting complex of photosystem 2 and pigments was attained at different fluence rate levels. In black pine, blue light compared to the red of the same fluence rate level either activated or reduced accumulation of pigments and LHC proteins, the effect being dependent on its fluence rate level. At fluence less than 3.0 mu-mol m-2 s-1, blue light was more efficient for the synthesis of Chl a, b and carotenoids, but for LHC-2 complexes, fluence rates between 0.4 and 1.5 mu-mol m-2 s-1 were more effective. In pine the effects of the two lights on the accumulation of pigments and LHC proteins were demonstrated separately and were dependent on fluence rate level. This suggests irradiance-controlled activation/deactivation of the photoreceptor at the level of the cell. C1 USDA ARS,NO REG RES CTR,PEORIA,IL 61604.

To determine whether this mycotoxin can be translocated through the ear in the absence of hyphae, we harvested 21 grains from around each of 21 wound-inoculation sites of maize ears matured at 34/30 C (day/night). Individual grains were analyzed for aflatoxin by enzyme-linked immunosorbent assay. Maize spikelets are borne in pairs and, if aflatoxin is transported in the rachis, grains in a pair should have similar toxin levels, but nonpaired grains may or may not. Statistical treatment showed that no two grains chosen at random had different average toxin levels: there was no pattern discernible in toxin accumulation. Highly contaminated individual grains rarely had highly contaminated neighbors. Finally, of the 413 grains assayed, almost 80% either were aflatoxin-positive and showed signs of the fungus or were not aflatoxin-positive and had no signs of the fungus. Only 58 grains (14%) had detectable toxin levels without fungal signs. We conclude that long-distance transport of aflatoxin does not occur in infected ears independently of the hyphae.

Plants were inoculated 21 days after style emergence; wounded grains and adjacent spikelets (with their rachis segments) were harvested at intervals up to 28 days later. Tissues were processed for plastic embedding and 1.5-mu-m thick sections were examined by bright field microscopy. The fungus spread from the wound sometime after 14 days postinoculation, and at 28 days postinoculation it could be found in small amounts throughout all rachis tissues except the pith and lignified fibers. The fungus entered the rachillae of adjacent spikelets from the rachis and also from the bracts at their insertion point. The fungus grew through the aerenchyma in the rachilla to the floral axis and innermost layers of the pericarp (the endocarp). Hyphae did not penetrate to the endocarp from the exterior of the pericarp. The hyphae were always intercellular in the rachis, rachilla, and pericarp. They were both inter- and intracellular in the floral axis and internal to the testa (i.e., inside the seed proper). From the endocarp, entry into the seed was not across the black layer; random tears in the testa over the embryo were the probable immediate pathway. Hyphae were vacuolate everywhere except in the seed. Host cells died (and even collapsed) ahead of the fungus, but no other structural alterations were seen.

In addition, leaf protein was extracted, and the activity and amount of totally activated Rubisco were determined by (CO2)-C-14 assimilation and gel electrophoresis. No significant reductions in net photosynthesis, Rubisco activity, or stomatal conductance, or increases in stomatal limitation of photosynthesis were detected in the infected resistant clone by either in vivo or in vitro methods. Net photosynthesis, Rubisco activity, and stomatal conductance were reduced significantly in the infected susceptible clone, but stomatal limitation of net photosynthesis was not affected. There was a significant reduction in both the total activity and amount of Rubisco in the infected susceptible clone. The lack of effect of reduced stomatal conductance on net photosynthesis coupled with the reduction in amount and activity of Rubisco support the conclusion that the reduction in net photosynthesis in the infected susceptible clone was due to the reduction in Rubisco activity.

Diseased plants are characterized by stunting, leaf rolling, and leaflet chlorosis. The disease occurs only in fields with a history of previous tomato crops and can reduce yields by as much as 80%. Although TPD is known to be soilborne, the cause of the disease has not been determined until now. Tomatoes grown at 14 C in soil collected from a field with a history of TPD became infected with a tombusvirus that was serologically indistinguishable from the BS-3 strain of tomato bushy stunt virus (TBSV). When tomato debris infected with TBSV was used to infest soil, seedlings planted in this soil developed symptoms of TPD and were positive for TBSV infection if grown at 16 C. In addition, TBSV was consistently found associated with field-grown, symptomatic plants collected during 1987 and 1988, as determined by ELISA. Eight tomato cultivars, which in field observations were considered to be susceptible or tolerant to TPD, were mechanically inoculated with TBSV and grown in the greenhouse. The symptoms were most severe on the TPD-susceptible plants, but were mild on TPD-tolerant plants. Symptom development was also found to be dependent on temperature in a manner consistent with temperature sensitive replication of the virus. These experiments implicate TBSV as the etiological agent of TPD. C1 UNIV CALIF EL CENTRO,EL CENTRO,CA 92243.

The capsid protein of virus purified from young systemically infected leaves had an apparent size of 45 kDa in 12% sodium dodecyl sulfate-polyacrylamide gels with minor amounts of 43, 42, 33, and 31 kDa proteins. The proportion of smaller proteins increased with the age of the leaf. In some virus preparations only 31 kDa capsid protein was detected. In vitro proteolysis of virions with 45 kDa protein produced virions with 31 kDa protein. Virions with 31 kDa capsid protein sedimented slightly more slowly than those with 45 kDa protein. Antiserum to intact virions, containing predominantly 45 kDa protein, reacted with both 45 and 31 kDa proteins on Western blots. Thirteen isolates of WSMV could be classified into two groups with major capsid proteins of 47 and 45 kDa, respectively, as well as accompanying minor proteins. Most natural isolates, including Sidney 81, contained 45 kDa protein, but the type strain contained 47 kDa protein. C1 UNIV NEBRASKA,NEBRASKA AGR EXPT STN,DEPT PLANT PATHOL,LINCOLN,NE 68583.

For most planting dates, lesions were first observed at soybean growth stage V2 or V3 (unrolled leaf occurred at second or third nodes on main stem), indicating the presence of inoculum near the time of planting. The development of disease was affected by the growth of soybean, of which the growth periods varied from 83 days to 207 days for different planting dates. On the autumn-seeded crop, disease reached the maximum level 40-60 days after planting. On the summer-seeded crop, disease onset was 20-40 days later than that of spring- or autumn-seeded crop, and disease reached the maximum level 80-100 days after planting. Physiological days were used as a measure of biological time for both the soybean plant and the rust pathogen. Total leaf area per plant was closely described using plant physiological day as an independent variable with R2 greater than 0.88 (n = 215-235). A disease model using physiological day of plant and physiological day of pathogen as independent variables was used to calculate the disease development with data pooled from all the plantings, and R2 = 0.69 (n = 696) for G 8587 and 0.75 (n = 589) for TK 5. Defoliation was significantly explained with regression on disease severity (R2 = 0.625-0.809, P < 0.0001); however, error increased when disease severity was low. Estimation of yield loss using area under disease progress curve (AUDPC) as an independent variable resulted in a greater R2-value than using area under defoliation curve for each cultivar. The results were significantly improved when AUDPC adjusted for planting date effect was used as an independent variable for the regression.

While some of these genes are functionally similar and shared among microsymbionts nodulating genetically diverse legumes, others appear to encode host-specific nodulation (hsn) functions which allow for nodulation of plants within a given legume genus. More recently, genotype-specific nodulation (GSN) determinants have been identified in R. leguminosarum bv. viceae strain TOM and in B. japonicum strain USDA 110. GSN determinants refer to those bacterial sequences that allow for nodulation of specific plant genotypes within a given legume species. In contrast to the avr loci of several plant pathogens, rhizobial host-range determinants (hsn and GSN) have been shown to positively affect nodulation. That is, the introduction of exogenous hsn and GSN loci extends host-range. Since GSN loci have been reported to interact with single host plant alleles, it suggests that gene-for-gene interactions occur in rhizobiallegume symbioses and contribute to nodulation specificity at the host genotype level.

In Pseudomonas fluorescens 2-79, which suppresses take-all of wheat, the importance of the antibiotic phenazine-1-carboxylic acid was established with mutants deficient or complemented for antiobiotic production and by isolation of the antibiotic from the roots of wheat colonized by the bacteria. Genetic and biochemical studies of phenazine synthesis have focused on two loci; the first is involved in production of both anthranilic acid and phenazine-1-carboxylic acid, and the second encodes genes involved directly in phenazine synthesis. Because the antibiotic does not account fully for the suppressiveness of strain 2-79, additional mutants were analyzed to evaluate the role of the fluorescent siderophore and of an antifungal factor (Aff, identified as anthranilic acid) that accumulates when iron is limiting. Whereas strains producing only the siderophore conferred little protection against take-all, Aff+ strains were suppressive, but much less so than phenazine-producing strains. Iron-regulated nonsiderophore antibiotics may be produced by fluorescent pseudomonads more frequently than previously recognized, and could be partly responsible for beneficial effects that were attributed in the past to fluorescent siderophores.

Properties of a siderophore transport system which might provide a competitive advantage under iron stress conditions include ability to utilize other organisms' siderophores, higher Fe(III) stability constant, faster kinetics of dissolution of Fe(III) minerals, more efficient transport system, and resistance to degradation. In order to determine the concentration and localization of siderophores in the rhizosphere monoclonal antibodies (Mabs) to ferric pseudobactin, the siderophore of Pseudomonas putida B10, have been developed. Several Mabs cross reacted differently with various pseudobactins. A growth medium has been developed for the study for siderophore-mediated rhizosphere interactions in the laboratory.

Daily mid-afternoon decreases in PSI-leaf of up to 1.5 MPa and in net photosynthesis of up to 50% were typical for irrigated sunflower during seed filling. These mid-afternoon values were lowered an additional 0.6 to 0.8 MPa by prolonged drought treatment. There was a nearly linear relationship between the decline in net photosynthesis and reductions in leaf conductance over the course of the day. Thus, it was unexpected to find that the low, midafternoon rates of photosynthesis were associated with the highest intercellular CO2 concentrations. These and other observations suggest that the daily decline in photosynthesis represents a 'down regulation' of the biochemical demand for CO2 that is coordinated with the diurnally developing need to conserve water, thus establishing a balanced limitation of photosynthesis involving both stomatal and non-stomatal factors. There were no indications that either short term (i.e. diurnal declines in PSI-leaf) or long term (i.e. drought treatment) water deficits caused any damage or malfunctioning of photosynthesis. Rather, both the daily declines in photosynthesis and the nearly 25% decrease in leaf area induced by prolonged drought appeared to be well-controlled adaptive responses by field-grown sunflower plants to limited water availability.

Two isozymes of AAt (AAT-1 and AAT-2) occur in alfalfa (Medicago sativa L.). Antibodies against alfalfa nodule AAT-2 do not recognize AAT-1, and these antibodies were used to study AAT-2 expression in different tissues and genotypes of alfalfa and also in other legume and nonlegume species. Rocket immunoelectrophoresis indicated that nodules of 38-day-old alfalfa plant contained about eight times more AAT-2 than did nodules of 7-day-old plants, confirming the nodule-enhanced nature of this isozyme. AAT-2 was estimated to make up 16, 15, 5, and 8 milligrams per gram of total soluble protein in mature nodules, roots, stems, and leaves, respectively, of effective N2-fixing alfalfa. The concentration of AAT-2 in nodules of ineffective non-N2-fixing alfalfa genotypes was about 70% less than that of effective nodules. Western blots of soluble protein from nodules of nine legume species indicated that a 40-kilodalton polypeptide that reacts strongly with AAT-2 antibodies is conserved in legumes. Nodule AAT-2 immunoprecipitation data suggested that amide- and ureide-type legumes may differ in expression and regulation of the enzyme. In addition, Western blotting and immunoprecipitations of AAT activity demonstrated that antibodies against alfalfa AAT-2 are highly cross-reactive with AAT enzyme protein in leaves of soybean (Glycine max L.), wheat (Triticum aestivum L.), and maize (Zea mays L.) and in roots of maize, but not with AAT in soybean and wheat roots. Results from this study indicate that AAT-2 is structurally conserved and localized in similar tissues among diverse species. C1 UNIV MINNESOTA,DEPT AGRON & PLANT GENET,ST PAUL,MN 55108.

Previous work in this laboratory has demonstrated that the bolting aspect (rapid stem growth) of reproductive development is mediated by gibberellins (GA). The present paper describes the selection and characterization of a mutant lacking the capacity for thermoinduced stem growth. Seeds of an inbred field pennycress line (CR1) were treated with the chemical mutagen ethyl methane sulfonate, germinated, and allowed to produce seed. Plants derived from these seeds were screened for reduced stem growth. A mutant line, EMS-141, in which the lack of stem growth can be fully overcome with exogenous GA3, was selected for further analysis. Other phenotypic abnormalities exhibited by the mutant line include reduced petiole growth, slightly delayed floral initiation, and failure of flowers to develop fully. These are also reversed with exogenous GA3. Evidence is presented indicating that all of the alterations in growth and development exhibited by EMS-141 are conferred by a recessive mutation of a single nuclear gene. Through quantitative analysis of endogenous GA and GA precursors and a comparison of the abilities of various compounds to restore normal growth when applied to plants of EMS-141, the physiological basis for the mutant phenotype was determined to be the result of highly reduced endogenous GA levels. Moreover, the affected site in GA biosynthesis appears to be the accumulation of ent-kaurene, probably at the level of ent-kaurene synthase. The relative abilities of exogenous GA and GA precursors to restore normal growth of petioles and stems are compared, and the results are used to make inferences on the functions of the two different pathways of GA metabolism that exist in field pennycress.

There were large differences among cultivars in the rates at which leaf water potential (PSI-L) and gas exchange activity declined when irrigation was discontinued. Pressure-volume curve analysis indicated that increased leaf water deficits in droughted plants led to reductions in bulk leaf elasticity, osmotic potential, and in the PSI-L at which turgor loss occurred. Adjustments in PSI-L at zero turgor were not sufficient to prevent loss or near loss of turgor in three of five cultivars at the lowest values of midday PSI-L attained. Maintenance of protoplasmic volume was more pronounced than maintenance of turgor as soil drying progressed. Changes in assimilation and stomatal conductance were largely independent of changes in bulk leaf turgor, but were associated with changes in relative symplast volume. It is suggested that osmotic and elastic adjustment contributed to maintenance of gas exchange in droughted coffee leaves probably through their effects on symplast volume rather than turgor.

This observation contrasts with the Spinacea oleracea (spinach) and Arabidopsis thaliana proteins, in which two polypeptide species are generated by alternative pre-mRNA splicing. A Chlamydomonas rubisco activase cDNA clone containing the entire coding region was isolated and sequenced. The open reading frame encoded a 408 amino acid, 45 kilodalton polypeptide that included a chloroplast transit peptide. The presumptive mature polypeptide possessed 62% and 65% amino acid sequence identity, respectively, with the spinach and Arabidopsis mature polypeptides. The Chlamydomonas rubisco activase transit peptide possessed almost no amino acid sequence identity with the higher plant transit peptides. The nucleotide sequence of Chlamydomonas rubisco activase cDNA provided no evidence for alternative mRNA splicing, consistent with the immunoblot evidence for only one polypeptide. Genomic DNA blot analysis indicated the presence of a single Chlamydomonas rubisco activase gene. In the presence of spinach rubisco activase, a lower extent and rate of activation were obtained in vitro with Chlamydomonas rubisco than with spinach rubisco. We conclude Chlamydomonas rubisco activase comprises a single polypeptide which differs considerably from the higher plant polypeptides with respect to primary structure.

The development of these functions was followed in glyoxysomes and ER isolated on sucrose gradients from castor bean endosperm daily from 0 through 6 days of germination. On a per seed basis, glyoxysomal and ER protein, glyoxysomal and ER membrane redox enzyme activities, and glyoxylate cycle activities peaked at day 4 as did the ER membrane content of cytochrome P-450. NADH:ferricyanide reductase was present in glyoxysomes and ER isolated from dry seed. This activity increased only about twofold in glyoxysomes and threefold in ER during germination relative to the amount of protein in the respective fractions. The other reductases, NADH:cytochrome reductase and NADH:ascorbate free-radical reductase, increased about 10-fold in the ER relative to protein up to 4 to 5 days, then declined. NADPH:cytochrome reductase reached maximum activity relative to protein at day 2 in both organelles. The increases in redox activities during germination indicate that the membranes of the ER and glyoxysome are being enriched with redox proteins during their development. The development of redox functions in glyoxysomes was found to be coordinated with development of the glyoxylate cycle. C1 GEORGE WASHINGTON UNIV,DEPT BIOL SCI,WASHINGTON,DC 20052.

When the ethylene biosynthesis-inducing xylanase (EIX) was applied to cut petioles of detached tobacco leaves, it induced ethylene biosynthesis within 1 hour and extensive electrolyte leakage and necrosis were observed in tobacco leaf tissue within 5 hours. Ethylene-pretreatment (120 microliters per liter ethylene for 14 hours) of tobacco leaves enhanced ethylene biosynthesis in response to EIX by more than threefold and accelerated development of cellular leakage and necrosis. In intact plants, similar symptoms could be induced in leaves that were distant from the point of the enzyme application. The evidence suggests that EIX is translocated via the vascular system and elicits plant responses similar to those observed in a hypersensitive response.

The consumer demand for poultry products, especially poultry meat, can be expected to remain strong. Today's key issues for poultry producers, processors, and retailers will likely remain significant through the 1990s: bacterial infections and contamination, other diseases, drug residues, cholesterol and other nutritional concerns, and animal welfare. In all of these areas, government involvement will continue through research and extension. However, future levels of federal involvement are inextricably tied to future levels of appropriate funding for research and extension, an uncertain proposition at best. Although the federal establishment is preparing for a future that may be seriously constrained by reduced budgets, there are several trends expected to continue until the year 2000 and beyond: 1) Environmental issues will continue to be a major driving force, if not the single most important factor, affecting federal agricultural programs. 2) Research on poultry will focus on improving animal nutrition, preventing disease, breeding for desirable nutritional characteristics such as leanness, and reducing the incidence of bacterial contamination during processing and handling. 3) Without compromising the traditional separation of public and private responsibilities, government and academia and industry will work more closely in identifying problems and developing practical solutions.

Calculations involved digital numbers from single transects of pixels representative of each stand and from a full spatial matrix of pixels from each stand. Digitized aerial video images having pixel sizes of 1 m, 10 m, and 30 m were used. At 1 m spatial resolution the ranges of the matrix semivariograms related to the mean tree canopy sizes of the stands. The sills responded to the presence of vertical layering in the canopies and to percent canopy cover. The transect semivariograms were less representative of overall stand structure, but exhibited periodicity that was suggestive of patterns in stand structure. Semivariograms based on 10 m and 30 m pixels contained significantly less useful information. The ranges of the 10 m matrix semivariograms revealed only whether the tree canopy sizes were less than 10 m or were between 10 m and 20 m. The sills were greatly reduced, but still related well to canopy layering and percent cover. Periodicity in the transect semivariograms was greatly reduced, and in some cases, eliminated. At 30 m resolution, only the sills of the matrix semivariograms contained useful information. However, actual differences between the sills were small.

The spot prices of lead, tin and zinc over the period January 1964 to December 1987 have served as the basis of the analysis. The results show that spot prices for lead and both tin and zinc are cointegrated at the 1% level. This means that these markets are not efficient in the semistrong form sense since causality must run in at least one direction. There is also evidence of a weaker (in a statistical sense) cointegrating relationship between the spot prices for tin and zinc. C1 USDA,WASHINGTON,DC.

However, most studies comparing duration of cultivation to organic matter changes are usually confounded by differences in soil type and/or management practices or are restricted to comparisons of a single long-term cultivation period with an adjacent rangeland site. Our study was conducted to determine short- and long-term changes in soil properties due to cultivation where major influences from soil type and management were minimal. Four contiguous sites where cultivation had occurred for 0, 3, 20, or 60 years were sampled. Soil samples were analyzed for total and labile organic C, N, and P concentrations and for selected physical and chemical properties. Increasing years of cultivation resulted in decreasing silt content of the soil surface and a decrease in depth of lime. After 60 years of cultivation, total soil organic C, N, and P had declined by 55-63% in the surface 15 cm, but about half of this loss occurred during the first 3 years of cultivation. In comparison, the labile fractions of the organic C and N declined by 67-72% after 60 years, but over 80% of labile C loss and more than 60% of the labile N loss occurred during the first 3 years of cultivation. Although half of the total decline in P came from the organic P pool, this decline represented about a 60% decrease in the organic P level in the first 3 years. The proportion of organic C in labile form declined after 3 years of cultivation but thereafter increased to a proportion comparable to the adjacent rangeland condition. The proportion of organic N in labile form was not significantly affected by cultivation. The data indicate that this sandy soil is highly susceptible to organic matter decomposition with cultivation. C1 USDA ARS,FT COLLINS,CO 80522.

Prior to enactment of the Wyoming Environmental Quality Act of 1973 approximately 8,000-10,000 hectares were abandoned. Since topsoil was not salvaged during mining, exposed spoil serves as the plant growth medium for current reclamation efforts. Wood residue amendment consisting of Ponderosa pine [Pinus ponderosa Laws] bark, woodchips, and sawdust were incorporated into the surface 30-cm layer of spoil resulting in improved physical and chemical characteristics. The improved physical characteristics of the spoil resulted in improved water relations in the spoil which enabled vegetation establishment and the leaching of soluble salts from the surface 15 cm of spoil during the 4 years when precipitation was at least 80% of normal. However, leaching of soluble cations resulted in increased sodium-adsorption-ratio because of the disproportionate concentration of sodium in the total soluble cation pool. These findings indicate the need for a calcium amendment to promote long-term amelioration of sodicity. Aboveground biomass of perennial grasses planted on the amended spoil responded positively to increasing wood residue rates. This research has led to the development of reclamation technology for abandoned bentonite mined lands that utilizes wood residue and inorganic calcium amendments (gypsum, calcium chloride, and phosphogypsum).

Magnetic susceptibility was measured on every sample, particle size distribution and organic matter content on alternate samples, and elevations at 5 m intervals along the transect. Magnetic susceptibility values were larger on the summit and sideslopes, smallest in the drainageway, and related to sand content (parent material) and soil wetness (landscape position). The sand content of the soil followed a similar pattern to the magnetic susceptibility. Clay and organic matter content increased slightly along the transect and did not appear to be related to landscape position or soils. Semivariograms based on magnetic susceptibility, sand, and silt contents displayed ranges of 59 to 64 m, indicating boundaries at approximately 60 and 120 m; these roughly seperated the well- and moderately well-drained soils from the poorly-drained soil. A moving split window technique was used as a numerical method for boundary location. Textural components provided a general indication of the boundaries among the three soil series, but magnetic susceptibility data partitioned the transect with more distinct boundaries which clearly delineated the soil series. Magnetic susceptibility can be measured in situ at numerous locations much more quickly than texture, and additionally it accounts for drainage conditions of the soil. Its use in soil survey looks very promising. C1 BALL STATE UNIV,DEPT NAT RESOURCES,MUNCIE,IN 47306.

The results indicated that removal of both antennae from males reduced mating in small cages with control (intact) females by an average of 65% compared to mating by control males. Removal of one-half of each or one antenna had little effect on mating. Removal of both male antennae reduced trap catch of released males in wind tunnels to 4% compared to 63% for untreated males. Removal of one antenna reduced trap catch to 24%. Antenna with all except one to three flagellomeres (subsegments) removed were nearly as functional as complete antenna. Females with both antennae ablated mated as successfully as untreated females (average of 85% mated in 1 night). Mated females lacking antennae deposited their eggs in the same sites as untreated females (oviposition substrate, cage interior) but produced 40% fewer eggs.

Treatments were: pure honey and a 51% honey water solution available for 1 hr or continuously, water available continuously, and no food or water. There were no treatment effects on fecundity or mortality during the first 24 hr after parasitoid emergence; mean first day fecundity across all treatments was 42.6 parasitized host eggs per female. The mean 4-day fecundity of females having continuous access to pure honey or to a 5% honey solution was significantly greater (79.7 and 70.2 parasitized host eggs per female, respectively) than for the other four treatments. The fecundity of females provided with no food or water was not significantly different from that of females provided water continuously or for 1 hr with honey or honey water. The daily availability of a 5% honey water solution allowed parasitoids to significantly outlive (10.8 day) those on all other treatments. Females provided daily with pure honey lived 9.2 days; combined longevity for the four other treatments was 2.4 days. The results show that daily access to food is necessary for maximum fecundity and longevity of individual females. When applied to the experimental mass rearing system, the two best food treatments diverted parasitoids away from host eggs. Since 51% of total fecundity is expended during the first day but A. iole lives for 8-14 days, no food may be most efficient in a mass production system by eliminating crowding by accumulated males and unproductive females.

Mean heterozygosity of these populations was 0.155 and 45.6% of the loci were polymorphic. All populations were similar genetically, with an average genetic distance of 0.026 and a fixation index (F(st)) of 0.085. The present population structure of the southeastern boll weevil gradually changes from being highly polymorphic with many rare alleles in southern Texas to less polymorphic with many rare alleles in southern Texas to less polymorphic with few rare alleles from Mississippi to North Carolina. These changes are believed to have been caused by man's agronomic, political, and economic practices which resulted in a barrier to gene flow between the different areas. Complicating this picture is man's use of laboratory-reared weevils for field experiments. C1 USDA ARS,WESTERN COTTON RES LAB,4135 E BROADWAY RD,PHOENIX,AZ 85040. USDA,FLORENCE,SC 29501.

Inlet sliver of 1.77, 2.47, and 3.18 ktex linear densities was supplied to the yarn core at rates required to produce yarns containing between 40 and 70% core. To make yarns of the same size and core ratio, lighter core silver had to be supplied at faster inlet speeds or heavier core silver at slower speeds. Using lighter core silver at greater inlet speeds improved yarn strength and evenness. Among these, coarser yarns and those with higher core ratios showed better uniformity. Yarns supplied by lightweight core silver showed similar elongation; those supplied by heavyweight core silver showed more variation over the range of core ratios.

Approximately 50% of the assimilated carbon was lost during this time, presumably through respiration. Most of the C-14 recovered in the plant remained in the source leaf. Most of the exported C-14 was found in stems and especially roots. Position of the source leaf did not affect distribution of translocated C-14; however, upper source leaves retained slightly more C-14 than lower source leaves. Most C-14 in all tissues was found initially in sugars. Labeled carbon in this fraction decreased rapidly and increased in other chemical fractions, particularly residue (structural carbohydrates and lignin). More C-14 was incorporated into residue than into any other chemical fraction, indicating continued growth by each of the tissues during the lag stage of seedling development. Labeled carbon increased in proteins for 6 to 12 h after treatment, then remained essentially constant for the remainder of the transport period, indicating both rapid incorporation of the pulsed C-14 into, and slow turnover of, the labeled protein components. In source leaves, C-14 incorporated into starch in the light was lost during the dark period, a typical diurnal storage pattern. In stems, C-14 in starch increased for 12 h, then decreased during the dark period, and then increased during the rest of the transport period. This pattern indicates that stems have both diurnal and long-term storage pools of starch. In roots, C-14 in starch increased rapidly for 12 h, then remained constant for the rest of the transport period, indicating primarily long-term storage in this tissue. Peak C-14 in amino acids in taproot preceded that in stem tissue, indicating recycling of C-14 from the roots to the shoot in amino acids.

Canopy PAR transmittance measured with the ceptometer was converted to LAI with the Beer-Lambert Equation. The ceptometer was sensitive to changes in PAR transmittance resulting from foliage growth. Predicted stand LAI ranged from 3.5 in the dormant season to a maximum of 5.3 in late July. Predicted LAI values were within 9% of values determined from destructive sampling. Published canopy extinction coefficients (k) were inadequate for converting PAR transmittance data to stand LAI because a significant amount of PAR was intercepted by dead branches and stems below the forest canopy. Because of interception by dead branches and stems, we estimated k = 0.84, which is substantially higher than previously reported values. The ceptometer was also sensitive to seasonal changes in PAR transmittance within the canopy. However, in contrast to predictions based on the Beer-Lambert Law, the relationship between proportional PAR transmittance (Q(i)/Q(o)) and cumulative LAI within the canopy was linear. Thus, vertical LAI distribution was best estimated with a linear model, as opposed to the non-linear model assumed in the Beer-Lambert Equation. We hypothesize that the linear relationship was a result of a gap in the canopy which was not represented by the cumulative leaf area distribution estimation procedure.

Bailey) from six even-aged stands in central Colorado, USA, of which three were at an elevation of 2800 and three at an elevation of 3200 m. Leaf longevity was 38% greater and annual shoot growth increment was 33% less in trees growing at 3200 m than in trees growing at 2800 m elevation. There was no difference in leaf biomass per shoot between the trees at the two elevations. These results suggest that leaf longevity is greater on shoots with low annual growth potential. Thus, a slow-growing tree at high elevation (low annual shoot growth potential) can have the same amount of foliage per shoot as a fast-growing tree at lower elevation. This plasticity in leaf longevity enables a consistency in foliar biomass per shoot, which may contribute to the wide range of sites and environments that lodgepole pine occupies successfully.

Some appeared healthy, with deep crowns, high leaf areas, nearly conical-shaped crown tops, and branches with live needles extending well back from the tip. Others with similar-sized boles appeared to be in a state of decline, having much shallower crowns, lower leaf areas, crowns that were flattened at the top, and "tufted" branches with needles only near the ends of the branches. Ten trees, five each in these two apparent vigor classes, were selected from a one-hectare area of a mature stand. Trees in the two groups were found to have similar height, diameter at breast height, age, and total volume. As expected from the selection criteria, high-vigor trees had much deeper crowns (P = 0.01) and higher leaf areas (P = 0.10). The volume of heartwood in the bole was higher in the low-vigor trees (P = 0.08), and the volume of the sapwood was higher in the high-vigor trees (P = 0.13). Sapwood and heartwood ages were similar in both classes. This suggests that, in earlier years, low-vigor trees reached a larger volume, represented by the present heartwood, than did the high-vigor trees (i.e., the current vigor rankings are the reverse of what they had been). The ratio of sapwood volume to total leaf area was not significantly higher in the low-vigor trees (P = 0.24), although this ratio varied tenfold among the data. Results suggest that a physiological basis for assessing vigor involving leaf area, sapwood, heartwood, age, and incremental growth data would identify a continuum of response from high- to low-vigor trees rather than discrete groups based on visual appearance.

The theoretical basis for the ECOPHYS model is that (1) individual leaves drive and control growth; (2) the microenvironment at the leaf exerts primary control of photosynthetic rates; (3) leaf orientation is a major determinant of that microenvironment, (4) photosynthates produced by leaves are allocated among meristematic and respiratory sinks; and (5) the plant's genome and microenvironment regulate photosynthate allocation. The major driving variables are solar radiation, temperature, and clonal morphological and physiological factors. The user can interact or override any or all of the input variables to examine the effects of such changes on photosynthetic production and growth. Verification and sensitivity analyses of ECOPHYS are presented and discussed. The use of ECOPHYS as a research tool is illustrated with several examples.

This photosynthesis model was validated by comparing predicted photosynthate production values for individual leaves and the total tree with hourly field measurements collected on four days spaced throughout a growing season. Simulated trees had identical numbers of leaves and leaf areas as the sample trees studied in the field, and hourly weather data collected on the plantation site were supplied as a model input. Total production for the four sample days ranged between 200 and 4900 mg CO2 tree-1 day-1. Model predictions of total daily photosynthate production were within 12% of the observed rates for three of the four sampling days. Diurnal variations in stomatal conductance and ambient CO2 concentrations and seasonal variations in area leaf weight were the primary sources of error. Total leaf area, proportion of sunlit leaf area, and photosynthetic efficiency were the most important factors influencing carbon dioxide exchange rates.

However, little is known about the variable influence of this phenomenon. Infiltration and interrill erosion were measured within a sagebrush-grass plant community during the winter, spring, and summer of 1989. Significant spatial and temporal differences in infiltration capacity and interrill erosion were found for shrub coppice dune and dune interspace soils. Infiltration was generally higher for coppice dune soils compared to interspace soils throughout the year. Infiltration capacity for both soils was lowest early in the year when the soil was frozen or saturated, then increased as the soil dried in the spring and summer. Interrill erosion was consistently lower for coppice dune soils compared to interspace soils. Erosion from interspace soils was greatest during a 19-day period in late winter characterized by diurnal freeze-thaw cycles, saturated surface soil conditions, and soil slaking.

Tolerant 'Caldwell', and susceptible 'Abe' and 'Talento' cultivars were infected with the P-PAV and RPV-NY isolates of BYDV using the bird cherry-oat aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae) as vector. Total Fructose Equivalents (TFE), Total Reducing Sugars (TRS), Glucose (G), and Sucrose (S) content were determined every 5 d in leaf tissue collected starting 14 d after inoculation and up to 49 d post infection. No significant differences (P less-than-or-equal-to 0.05) were found 4 wk after seedling emergence (2 wk after infection) in TFE, TRS, G or S content in non-infected cultivars, except for higher TFE and G in 'Talento'. 'Abe' infected with the P-PAV isolate had more G than the other two cultivars. 'Abe' with RPV-NY had more S than RPV-NY infected 'Talento'. Comparing the effects of infection within cultivars, 'Caldwell' with P-PAV had a higher S content than non-infected plants. While 'Abe' with RPV-NY had a higher S content than healthy plants, and 'Talento' with P-PAV had higher TFE and G levels than non-infected plants; RPV-NY infected 'Talento' had higher G levels. The general trend from 14 to 49 d post infection suggested that BYDV infection increased tissue content of carbohydrates, particularly in TFE and G+S. It is possible that the increased fecundity of cereal aphids on plants infected with BYDV reported in other works could be due in part to this increased accumulation of carbohydrates after BYDV infection.

This study was designed to assess the potential of established perennial grasses to occupy two sites in the foothills ecosystem, Mediterranean/Maritime climatic regime, of southwest Oregon. Soils at Sites 1 and 2 are Darrow silty clay loam (fine, montmorillonitic, mesic Vertic Argixerolls) and Carney clay (fine, montmorillonitic, mesic Typic Chromoxerets), respectively, and annual precipitation at the sites averages 500 mm. Growth patterns of the perennial grasses were contrasted among each other and to the resident annual plants during fall, winter and spring growth periods. Of the perennial grasses, Idaho fescue (Festuca idahoensis Elmer), native to the area, and 'Beber' orchardgrass (Dactylis glomerata L.), introduced, most closely emulated the growth patterns of the resident annual grasses. These grasses initiated growth sooner, continued some growth through the winter and matured earlier than the other perennial grasses tested. Once established, Idaho fescue and Berber orchard-grass should be able to effectively compete with the resident annuals for resources and maintain their populations.

Our objective was to test the ability of spectral reflectance measurements with a portable hand-held radiometer to predict alfalfa phytomass. We used vegetative indices consisting of linear combinations of the near infrared (NIR) and red wavelength intervals, such as the NIR/Red ratio and normalized difference (ND). Reflectance measurements were taken during two grazing trials where alfalfa phytomass ranged from 200 g m-2 initially to negligible phytomass after 15 d of intensive grazing. A portion of the alfalfa was desiccated due to frost damage during the second trial. The ND and NIR/Red were well correlated with alfalfa phytomass (r = 0.87-0.97). Measurements taken at solar zenith angles (57 and 69-degrees) were found to produce similar ND/phytomass regression coefficients. The desiccated alfalfa increased red reflectance, which consequently lowered the ND and NIR/Red values. The ND was preferable to NIR/Red because it was more sensitive to low phytomass levels that are characteristic of grazing studies. An ND of 0.55 identified a threshold phytomass level, below which continued grazing caused a decrease in lamb weight gain. Handheld radiometric measurements are a quick, accurate, nondestructive means of estimating alfalfa phytomass in pasture grazing experiments. C1 USDA ARS,US WATER CONSERV LAB,PHOENIX,AZ 85040.

The PEG solution-seed contact effect on seed germination was evaluated on four grass species: sideoats grama [Bouteluoa curtipendula (Michaux) Torreyl, buffelgrass [Cenchrus ciliaris L.], Lehmann lovegrass [Eragrostis lehmanniana Nees], and kleingrass [Panicum coloratum L.]. A water potential control system for seed germination was developed that controlled PEG (8000 mol. wt.) solution-seed contact. Seeds were germinated on filter paper and cellulose membrane over the water potential range of 0.0 to -1.62 MPa. Buffelgrass and Lehmann lovegrass 21-d germination and germination rate index (GRI) were not affected by PEG solution-seed contact. Sideoats grama and kleingrass showed reduced germination and GRI without PEG solution contact on the cellulose membrane. The reduction was attributed to the hydraulic conductivity at the seed-water-membrane contact point which was influenced by PEG solution water potential and seed size and shape. Therefore, it was concluded PEG solution-seed contact does not reduce seed germination. RP EMMERICH, WE (reprint author), USDA ARS,ARIDLAND WATERSHED MANAGE RES UNIT,TUCSON,AZ 85719, USA.

Fries) in the USA. To determine whether crambe can be grown successfully on saline soils, a 2-yr-field-plot study was conducted. Five cultivars and three germplasm releases were grown with four salinity treatments imposed on a Pachappa fine sandy loam (mixed, thermic, Mollic Haploxeralf). Electrical conductivities of the irrigation waters, containing NaCl and CaCl2 (1:1 by weight), were 0.9, 3.7, 5.4, and 7.9 dS m-1. Seed yield, vegetative growth, and fatty acid composition of the seed oil were measured. Seed yield showed no statistical reduction over the salinity range tested each harvest year. Differences between harvest years were statistically significant. Analysis of the combined 2-yr data showed a 6.5% reduction of the combined 2-yr data showed a 6.5% reduction of seed yield for each unit increase in soil salinity above 2.0 dS m-1. These results place crambe in the moderately sensitive salt tolerance category. Individual seed weight was significantly reduced by salinity for six of the eight cultivars or germplasms studied. Increased salinity did not significantly affect the erucic acid component of the seed oil, but did significantly reduce the oleic, linolenic, and eicosenoic components.

Development of legume cropping systems which will permit reseeding of winter cover-crop legumes is a promising approach to reducing legume establishment costs. Field studies were conducted in Alabama for 4 yr on Wynnville sandy loam and Dothan fine-sandy loam soils (fine-loamy, siliceous, thermic, Glossic Fragiudults and Plinthic Paleudults, respectively) to determine the effects of both cash crop and winter cover-crop legumes in cropping systems on N fertilizer requirements of corn (Zea mays L.) grown in a conservation-tillage system. On the Wynnville soil, soybean (Glycine max L. Merr.) was more effective in providing early season N, and clover (Trifolium incarnatum L.) in providing late-season N. The system with both soybean and clover resulted in an even more effective contribution of N to corn grain yield, and a higher yield level than that of continuous corn regardless of N fertilizer rate. On the Dothan soil, the benefits of cropping systems were not as pronounced, and the responses were eliminated by N fertilization, suggesting increased yields were due to N and not to a rotation effect. On both soils, in years of adequate and inadequate rainfall, the reseeding crimson clover system, in combination with a soybean-corn rotation consistently produced the highest yields of the systems studied, and provided a 68 to 159 kg N ha-1 fertilizer equivalent for corn.

Ceramic spheres were evaluated as tracers to determine the effects of chisel and moldboard tillage on the vertical distribution of shattered seeds. Tracers and seeds of foxtail millet (Setaria italica [L.] Beauv.) were applied to the soil surface [Ves loam (a fine-loamy, mixed, mesic Udic Haplustoll)] before fall primary tillage with a chisel or moldboard plow. Soybean (Glycine max [L] Merr.) and oat (Avena sativa L.) were grown in a strip-plot design. Soil cores (18 mm diam.; 60 cm deep) were taken midsummer, sectioned into 2-cm increments, and composited (12-15 cores per sample) by depth. Soil bulk density, seed counts, and tracer counts were recorded for each sample. Seeds and tracers were found to depths of 12 cm in the chisel plots and 32 cm in the moldboard plots. In the chisel plots, 51 and 48% of the seeds and tracers, respectively, were found within 4 cm of the surface compared to 11 and 4% for the moldboard plots. Germination of applied seeds was greater in the chisel plots whereas germination of indigenous seeds (previously buried by tillage) was greater in the moldboard plots. An abrupt increase in the soil bulk density occurred at the penetration depth of the primary tillage operation and coincided with the maximum burial depth of seeds and tracers. These observations verify the differences in working depth and associated seed placement by the two implements. Ceramic spheres can trace the vertical distribution of shattered seeds related to tillage. C1 UNIV MINNESOTA,SW EXPT STN,LAMBERTON,MN 56152. UNIV MINNESOTA,USDA,ARS,ST PAUL,MN 55108.

But the fact that it is affected by environmental stress limits its use for intercrop or intercultivar comparisons. Fair comparisons should be based on estimated genetic HI for a given environment, but a procedure to determine the same is lacking. We propose that the slope of an upper-bound in the grain yield vs. dry matter plot passing through the origin approximates the genetic HI because the highest grain yields against given dry matter represent the least-stressed and/or stress-adapted plants and passage of the line through the origin is necessary to satisfy the definition of HI. This HI also provides a useful reference for interpreting agronomic data with respect to stress effects associated with management practices. The HIs of sorghum [Sorghum bicolor (L.) Moench], corn (Zea mays L.), and wheat (Triticum aestivum L.) were estimated by the upper-bounds of grain yield (corrected to dry weight) vs. dry matter yield taken from existing reports in the literature. Harvest index of sorghum and irrigated corn ranged between narrow limits of 0.48 to 0.53 and 0.58 to 0.60, respectively. Harvest index of irrigated wheat ranged from 0.38 to 0.47. Stress effects on HI are illustrated in plots of published and unpublished (dry) grain yields vs. dry matter yields and reasons for the same are discussed.

This study was initiated to investigate the process of stemflow, and to provide quantitative data on the distribution of rainfall under a corn (Zea mays L.) canopy. Rainfall distribution under the canopies of replicate conventional till corn plots was investigated by placing rainfall collectors at discrete locations within small 1.6-m by 0.76-m areas of the plots. Collection cups were also fixed around the stalks of individual corn plants to quantify stemflow. Results obtained from eight storm events in 1987 revealed that corn plants channel 19 to 49% of the total rain inputs down the stem to the base of the stalk. This stemflow plus the rainfall impinging directly in the planting furrow, accounted for approximately 42% of the total water inputs from a given storm event. These increased water inputs to the planting furrow may have implications in modeling solute leaching and runoff as well as to modifying current fertilizer and pesticide application methods.

This study was conducted to evaluate the meter-stick method and an electronic method of measuring canopy cover for accuracy, speed, and ease of use. Canopy cover of winter wheat [Triticum aestivum L.], corn [Zea mays L.], and soybean [Glycine max (L.) Merr] was measured weekly in 1988, using a meter stick and a DECAGON Ceptometer. Canopy cover ranged from 74 to 97% for wheat, 2 to 95% for corn, and 2 to 65% for soybean. There were no significant differences in canopy cover determinations by the two methods. The Ceptometer was faster, simpler, and as accurate as the meter stick. RP ARMBRUST, DV (reprint author), KANSAS STATE UNIV AGR & APPL SCI,USDA ARS,ROOM 105-B E WATERS HALL,MANHATTAN,KS 66506, USA.

I. terricola was the most divergent species of the genus, differing from other members by 18% nucleotide differences in the highly variable 25S-635 region. These data indicate Issatchenkia to be the most divergent ascomycetous yeast genus presently known.

Hourly 10-cm-depth soil temperatures were used as input to the model. Hourly soil temperatures were predicted from daily minimum and maximum 10-cm-depth soil temperatures using a half-sine-wave approximation, or from minimum and maximum daily 1-m-height air temperatures using a model for predicting soil temperature from air temperature. The mean difference in the number of days between predicted and observed 50% emergence was 0.22 days using soil temperatures and 0.00 days using air temperatures. Linear regressions of predicted versus observed 50, and 90% cumulative beetle emergence from the soil indicated that model predictions were reasonably accurate and precise using both soil and air temperatures.

Multiple strains of genetically defined heterothallic species of Rhodosporidium, Leucosporidium, Cystofilobasidium, and Sporidiobolus demonstrated that nucleotide sequences within these species are homologous and that differences between species range from 1 to 20 or more bases. Also included in this study were several homothallic species of these teleomorphic genera and some anamorphs assigned to Rhodotorula and Candida. Those results indicated close relationships among certain homothallic species, particularly in the genus Mrakia, and potential relationships of homothallic and anamorphic strains to several teleomorphs. The data suggest that LSU sequences can be used for yeast identifications with the possible exception of closely related homothallic species. C1 USDA ARS,NO REG RES CTR,PEORIA,IL 61604.

Maize from twelve genotypes (varieties) crossed to two testers was analyzed for aflatoxin B1 (AFB1) contamination at Baton Rouge, LA and Tifton, GA in 1987. Variety Philippines had the lowest amount of AFB1 at Baton Rouge and one of the lowest amount of AFB1 at Tifton. In the combined analysis of variance, the location X treatment X tester X variety interaction was significant. This interaction was analyzed and a stability variance (sigma-i2) statistic calculated. Mean AFB1 accumulation and stability of AFB1 production were examined simultaneously, i.e., variety ranks for AFB1 and sigma-i2 were summed. The most desirable (lowest rank sum) variety across locations, testers, and treatments (inoculation and control) was St. Charles White, followed by Delta Prolific White, and Hopi. The most inconsistent AFB1 accumulation, along with high AFB1, was on Fino, Atkinson, USAWI, Navajo, and Michoacan-21. The ranks of varities between the inoculation and control treatments were different (r(s) = -0.51 for Baton Rouge and 0.29 for Tifton). The r(s) (rank correlation coefficient) for the control treatments between Baton Rouge and Tifton was 0.60 (P < 0.05) and that for the inoculation treatments was -0.20. The varieties identified in this study as having relatively low concentration of AFB1 should be useful to maize breeders in reducing AFB1 contamination in field maize.

Little information is available, however, regarding the comparative forage quality of the germplasm sources from which most USA cultivars were developed. We compared forage quality of these germplasm sources at four phenological stages under disease- and insect-free conditions in a greenhouse. Germplasm sources (cultivars) tested were: Indian (Sirsa #9), African (African), Peruvian (Hairy Peruvian), Flemish (DuPuits), Turkistan (Lahontan), Chilean (Kansas Common), M. varia (Grimm), and Ladak (Ladak). Four harvests were taken and forage was separated into four phenological stages: vegetative, early bud (1-3 buds-per-stem), late bud (> 3 buds-per-stem), and bloom. The germplasm source X phenological stage interaction was significant for crude protein (CP) and in vitro digestible dry matter (IVDDM) concentrations. M. varia showed the least decline in IVDDM and CP with increasing maturity. M. varia had higher IVDDM than did African and Indian at late bud and bloom stages. Indian and Flemish had higher CP than did Turkistan and Peruvian at late bud and bloom stages. Alfalfa germplasm sources differ in forage quality when comparisons are made within similar stages of phenological development.

The expression of c-fos was also monitored because of the potential role of that proto-oncogene in coordination of growth and differentiation. Preadipocytes were grown to confluence and then maintained in one of three media treatments: a) standard medium supplemented with 10% fetal bovine serum (FBS), b) FBS supplemented with dexamethasone (Dex), c) FBS supplemented with dibutryladenosine 3'-5'-cyclic monophosphate. Indirect measurements of growth indicated that cell proliferation did not differ due to media type. Histochemical and enzymatic measurements of adipocyte development revealed that differentiation occurred only in those cultures exposed to Dex. The increase in adipocyte differentiation in response to Dex was associated with a decrease in c-fos and actin RNA expression whereas the decrease in c-fos RNA expression in response to Dex was small (approximately 40%); immunocytochemical analysis indicated that induction of Fos protein occurred only in undifferentiated cells. Thus, the cells responsible for the decrease in c-fos RNA expression are possibly those signaled to differentiate into adipocytes. Expression of IGF-I RNA and secretion of IGF-I and PGE2 were also decreased in response to Dex treatment. These data provide the first demonstration that biosynthesis of IGF-I by preadipocytes can be modulated by a potent inducer of adipocyte differentiation. The combined results indicate that glucocorticoids may stimulate adipocyte differentiation by suppressing intracellular and putative intercellular mitogenic signals.

Weather data is automatically accessed from multiple national weather data networks; large-fire data is manually entered. A data-base management subsystem uses custom and commercial software packages to process and archive daily weather files. The decision support subsystem calculates the daily probability of a large wild land fire for every climate division in the country. The system produces onepage executive reports oriented to management by exception. On-site graphics software converts the reports into national and regional maps. The 99 percent reliable PC-based system predicted 75 percent of all large fires during 29 months of testing. RP SIMARD, AJ (reprint author), US FOREST SERV,1407 S HARRISON RD,E LANSING,MI 48821, USA.

We discuss the various roles of these allelochemics and the type of information needed to develop their use in pest control, which to date has been very limited. Rapid advancements are being made with respect to airborne chemicals and longer-range foraging behavior. Moreover, recent discoveries have shown that genetic diversity in parasitoid populations and phenotypic plasticity of individuals, together with their physiological state, often result in substantial variations in the response to chemical cues. Successful application of semiochemical-parasitoid systems will require management of these intrinsic parasitoid variables as well as management of the foraging environment. We illustrate emerging technology for such an application. For the immediate future, the development of this technology will allow us to: (1) define the genetic and phenotypic foraging profiles important to consistent and efficient parasitoid foraging and (2) establish the proper propagation and release procedures and monitoring bioassays necessary to ensure appropriate behavioral and physiological qualities of released organisms. For the long term, we envision technology for comprehensively manipulating the pest/crop environment in ways that would provide foraging stimuli and other needs important to retention and efficiency of parasitoids.

In this study, phenylpropanoid metabolism was examined over a 72 h time course in the weed sicklepod (Cassia obtusifolia) in relation to pathogenic effects of the fungus Alternaria cassiae. When 3- to 4-week old seedlings were challenged by the pathogen, extractable phenylalanine ammonia-lyase (PAL, E.C. 4.3.1.5) activity was dramatically increased above that in uninfected plants several hours after inoculation and exposure to dew. Greatest increases of enzyme activity (3-fold, specific activity basis) occurred at ca 15-23 h after treatment with fungal spores. After this peak of activity, PAL activity declined with time in infected tissue, but remained greater than in uninfected plants through 65 h after treatment. Total methanol-soluble hydroxyphenolic compound levels (PAL products) were higher in shoots (stems and leaves) of infected plants at 48-72 h. Leaves contained a higher concentration (per gram fresh weight) of hydroxyphenolic compounds than did stems, and infected leaves exhibited a phenolic content greater than that of uninfected leaves at ca 27-72 h. Increased soluble phenolic compound production correlated with the appearance of lesions and necrotic spots on leaves and stems. UV irradiation examination and spectrofluorometric analysis of thin layer chromatographic separations of methanolic extracts revealed a substantial increase of several components in infected tissue 48 h after inoculation. Results support the view that PAL activity increases correlate with increased phenolic compound production in this host/pathogen interaction.

The current study used a monoclonal antibody (mAb-E12) to identify a conserved antigen in the apical region of merozoites of seven species of Plasmodium (including rodent, primate and human pathogens), tachyzoites of Toxoplasma gondii, bradyzoites of Sarcocystis bovis, and sporozoites and merozoites of Eimeria tenella and E. acervulina. The antigen was also present in sporozoites of haemosporinid parasites. Immunofluorescence studies showed that the antigen was restricted to the apical 3rd of these invasive stages. Using immunoelectron microscopy, labeling was demonstrated in the region of the polar ring, below the paired inner membranes of the parasite pellicle, and near the subpellicular microtubules radiating from the polar ring of merozoites and sporozoites of E. tenella. The majority of the antigen could be extracted with 1% Triton-X 100, but a portion remained associated with the cytoskeletal elements. The molecule has a relative rate of migration (M(r)) of 47,000 in Plasmodium spp. and 43-46,000 in coccidian species. Since the epitope recognized by mAB-E12 is highly conserved, restricted to motile stages, and appears to be associated with microtubules, this antigen could be involved in cellular motility and cellular invasion.

Polyethylene glycol (PEG) and sucrose inhibited germination, first by preventing eversion of the filament, and then at higher concentrations by preventing stimulation. The size of the spore cases decreased by about 21% following germination, indicating an elastic spore wall and turgor pressure in the dormant spores. Increased pressure during germination was indicated by less osmotically-induced shrinkage in stimulated than in dormant spores and by higher concentration of solutes in the homogenates of germinated than ungerminated spores. These results are consistent with the hypothesis of a pressure increase during germination that is caused by an endogenous increase in solute concentration.

This species was found to be heterosporous with two concurrent sporulation sequences in the host larvae, both arising from diplokarvotic meronts and ending with haploid spores. One sequence was dominant and involved meiosis to produce eight thick-walled, broadly oval meiospores in a sporophorous vesicle (SV). The other sequence involved nuclear dissociation to produce lanceolate, thin-walled spores in a subpersistent SV. Horizontal transmission to the mosquito host, by one or both of two distinctly different pathways (one via an intermediate host the other by cannibalism of infected individuals) and by vertical transmission, are postulated but have not been demonstrated. A new species, Amblyospora trinus, is proposed and its affinities to other heterosporous microsporidia in mosquitoes are discussed. C1 ARMY MALARIA RES UNIT,INGLEBURN,NSW 2174,AUSTRALIA.

Our research addresses these goalds by determining cropping and tillage options required to achieve maximum profit for several specific soil erosion control goalds and by identifying the extent to which production inputs can be changed to minimize the loss of potential profit consistent with soil erosion control. A case study on a landscape from eastern Nebraska is used to convey the analytical approach used in the analysis. Irregular slope segments consisting of six landscape positions were considered when estimating soil loss using the universal soil loss equation. Upper and lower linear positions had the greatest erosion rates and the lowest gross margins of profit. Maximum gross margin was achieved in the field by planting continuous sorghum on the upper and lower interfluve positions and a sorghum-soybean rotation on the shoulder, upper and lower linear, and foot slope positions. Erosion control was increased by changing from conventional tillage to reduced and no-till systems and by farming on the contour. Erosion was reduced futher by substituting continuous sorghum and/or alfalfa for the sorghum-soybean rotation. Tradeoffs between profit and erosion control for combinations of tillage and cropping options were quantified. When erosion control objectives reduced potential profit below a desirable level, alternatives for reducing input costs were provided so that profit could be sustained. It is expected that this type of synthesis would lead to an integrated farming approach that includes goals for erosion control that are compatible with economic survival.

An alternative utilitarian approach, used in this study, addresses the capability of reclaimed land to properly function and sustain its intended post-mining use. A 5-year grazing study was conducted to evaluate the success of reclamation on uranium-mined land in Wyoming. Stocking rates of 0.25 and 0.5 steers ha-1 were replicated on 12 ha pastures to evaluate the effect of grazing on the vegetative community and animal response. Forage production and plant community compostiton of the pastures were not affected by stocking rate. However, the percentage of bare ground decreased 43% and litter cover increased 82% under both stocking rates. Native perennial grasses in the plant community increased 110%. Yearling steer gains were significantly greater on the low stocking rate, averaging 0.94 kg day-1 for the 0.25-steers-ha-1 and 0.81 kg day-1 for the 0.50-steers-ha-1 stocking rate. The increase in perennial native grasses and litter cover and the decrease in bare ground demonstrate that the ecosystem was not harmed and may have been improved by grazing.

Most soil erosion models do not account for these potential changes. How soil loss parameters change as a soil profile is progressively eroded away was studied on field sites located on a Grenada silt loam (fine silty, mixed, thermic, Glossic Fragiudalf) that represented virgin (uneroded), slightly eroded, moderately eroded, and severely eroded phases of the soil. Soil thickness above the fragipan were 100, 59, 42, and 19 cm, respectively. Simulated rainfall was applied to tilled plots at each site using an intensity of 7.3 cm h-1 for the initial "dry" run. The following day, multiple-intensity rainfall was applied to the plots wetted by the previous storm. Sediment in the runoff from row sideslopes for all storms totaled 80.3, 71.4, and 58.6 Mg ha-1 for the slightly, moderately, and severely eroded sites, respectively, whereas the virgin site yielded only 30.9 Mg ha-1. Runoff from these same sites totaled 1,067, 1,090, 1,144, and 1,028 Mg ha-1, respectively. Sediment size distributions at the virgin site were much coarser than those at the eroded sites, but the distributions among eroded sites generally were similar. The gradual decline in soil loss rates from eroded fragipan soils as profile thickness decreased illustrates the need for more thorough soil profile characterization and laboratory studies that relate soil properties to erodibility.

Photogeologic techniques and fieldwork on identifiable landforms were used to develop a terrain classification of sediment transfer. Terrain units formed the bases for assessing contemporary processes of sediment transport and for testing its usefulness in evaluating sediment flux. Contemporary behavior of terrain units suggests relative stability (short-term, i.e., 50 years) of the present system. The hillslope sediment transfer system appears to act as a closed system and is dominated by internal transfer of sediment moving on slopes with little clastic material entering the fluvial system. The method proposed here can be used by mountain park and wilderness area managers as a framework for determining alpine and subalpine ecosystem disturbance that results from recreational impact.

The compounds were detected by thin-layer chromatography (TLC) with confirmation by liquid secondary ion-mass spectrometry (SIMS) and by gas chromatography/mass spectrometry (GC/MS). Reference standards were isolated from cultures of F. moniliforme on corn. The level of fumonisin B1 was about 600 mg/kg in the culture material and 150 and 20 mg/kg in the two naturally contaminated samples.

Decay stages are generally defined from class I-V, with class I being the least decayed and class V being the most decayed. Fungi were isolated from cross-sections approximately 15 cm thick of Pseudotsuga menziesii logs in decay classes III and IV. Cross sections included portions of logs with and without conifer seedlings. Samples were removed from three vertical positions (top, middle, and bottom) of each cross-section. Comparisons of coefficient of community and detrended correspondence analysis ordinations indicated differences in community structure between class III and class IV logs. No community differences were found between samples with and without conifer seedlings. A total of 18 genera and 36 species of fungi were recovered from samples; more than 50% of recovered genera were dematiaceous hyphomycetes.

Growth of plants in the low-P, noninoculated soil was lowest, with total dry biomass reduced up to half of the low-P, inoculum treatment. Total nonstructural carbohydrates were 40% lower in leaves of plants in the low-P, noninoculated soil, compared with the other treatments. Inoculation of the low-P soil enhanced leaf (CO2)-C-14 incorporation by 67%, total chlorophyll content by 28%, and RuBPCase activity by 42%, compared with low-P, noninoculated treatment. Improved P-use efficiency by G.i. in low-P soil was comparable to high-P nutrition in improving leaf (CO2)-C-14 incorporation and concentration of major leaf photosynthetic products that include starch and sucrose. Leaf PEPCase activity in the low-P, noninoculated treatment, however, was at least threefold higher than the other treatments, suggesting a possible alteration in organic acid metabolism in sour orange leaves as a result of P deficiency.

To determine how different concentrations and ratios of NO3- and NH4+ in growth media influence the levels of A2bu and other free amino acids in the 'Lathco' flatpea cultivar, plants were grown hydroponically in controlled environments. The concentration of A2bu was highest in tissues when the NO3- to NH4+ ratio in the nutrient solution was low. Responses of amides and other nonprotein amino acids, especially in the roots, followed a similar trend. Free protein amino acids in leaves and stems were generally unaffected by changes in NO3- to NH4+ ratios. In roots, protein amino acids increased as the NO3- to NH4+ ratio in the growth medium increased. Ammonium inhibited shoot and root growth; NO3- alleviated the toxic effects of NH4+. Soluble protein concentrations were higher in the shoots of NO3- -fed plants in the roots of plants supplied with NH4+. These results suggest that accumulation of A2bu and other nonprotein amino acids, as well as asparagine and glutamine, plays a role in detoxification of NH4+ and storage of N.

This observation has raised concern that macropores may also promote rapid movement of agricultural chemicals to groundwater. This is a particular concern for no-till fields where lack of disruption by tillage can lead to the development of extensive macropore systems. In order to investigate the effect of initial rainfall on chemical transport, strontium bromide hexahydrate (SrBr2.6H2O) and atrazine (2-chloro-4-ethylamino-6-isopropylamino -s-triazine) were surface-applied to six 30 by 30 by 30 cm blocks of undisturbed soil obtained from a 25-yr-old, no-till corn (Zea mays L.) field with evidence of well-defined macropores attributable to earthworm activity. Half of the blocks then received a 1-h 5-mm simulated rain, which did not produce percolate. Two days later, the blocks received a 0.5-h 30-mm simulated rain, followed by another 0.5-h 30-mm rain 1 wk later. The remaining blocks received only the two 30-mm events. An average of 12% of the applied water passed through all the blocks during and shortly after the first 30-mm rain. Bromide, Sr, and atrazine losses in this percolate were 7, 10, and 2 times less, respectively, from blocks that received the 5-mm rain than from blocks not receiving this initial, light rain. The second 30-mm rain on the blocks not receiving the initial 5 mm produced 1.6X more percolate than the first 30-mm rain. Yet, transport and flow-weighted average concentrations of Br, Sr, and atrazine were all reduced. These results indicated that the first storm after application can move solutes into the soil matrix, thereby reducing the potential for transport in macropores during subsequent rainfall events.

This study was conducted to describe the desorption of SO4 from agricultural soils under experimental conditions applicable to the movement of SO4 in overland flow and runoff waters. The kinetics of SO4 desorption from soil were investigated at five different water/soil ratios (10:1-400:1), five time periods (5-180 min), and four SO4 additions (0-200 mg kg-1). Sulfate desorption (S(d)) was logarithmically related to contact time (t) and water/soil ratio (W) and was a linear function of the initial extractable SO4 content of soil (S(e)). The kinetics of SO4 desorption was described by the equation S(d) = K S(e) t-alpha W-beta, where K, alpha, and beta are constants for a given soil. This equation has previously been shown to describe desorption of soil P and K. The kinetic constants, K (r2 = 0.88), alpha (r2 = 0.83), and beta-(r2 = 0.88), were related to extractable soil Al content for 107 U.S. soils. The uniformity of equation constants for a given soil and the ease with which they can be estimated from extractable soil Al indicate the potential use of the equation in modeling SO4 desorption from soil and subsequent movement in surface runoff water.

During the growing season, the effect of no-tillage (NT) or conventional tillage (CT), location (between or within row), and N rate (0 or 56 kg N ha-1) on soil potential denitrification activity (PDA) and potential nitrification activity (PNA) was investigated. A Gilpin silt loam (fine-loamy, mixed, mesic Typic Hapludults) was selected and maize (Zea mays L.) was planted. For both PDA and PNA, most of the activity was concentrated in the soil surface (0-3.8-cm) layer, especially under NT, and decreased to barely detectable levels in the deepest (15-30-cm) layer examined. Significant main effects were found for tillage, season, and location for PDA in the soil surface layer. Tillage interacted only with season, resulting in an increase in PDA under NT, and a lack of response under CT, during the growing season in both the soil surface and the 3.8- to 7.6-cm layers. For PNA in the soil surface layer, significant main effects were found for all treatments. Only location interacted with tillage, resulting in a 50% increase in PNA from within rows to between rows under NT, and a lack of response under CT. In the 3.8- to 7.6-cm layer, the lowest order interaction was significant. In the 7.6- to 15-cm layer, PNA increased more rapidly under CT than NT during the growing season. These results demonstrate the importance of considering spatial distribution and time when these microbial activities are examined in tillage studies, and suggest that N losses under NT should exceed those under CT.

Microbial activity depends on soil water content and is maximum at a water content where the limiting effects of substrate diffusion and O2 supply are equal. The mechanism whereby this occurs and predictions of the soil water content where aerobic microbial activity is a maximum were the objectives of this study. In particular, this study predicted the shape of the microbial activity vs. water content function from soil physical concepts. Soil physical processes are assumed to influence microbial activity by limiting the steady flux of a required substrate or O2 to sites of microbial activity. Steady-state flux relations are used to define the activity function. The dependence of diffusion coefficient on water content or air-filled porosity is assumed. With these assumptions, it is possible to show that a maximum in the activity function exists. The predicted shape of the activity curve is consistent with experimental observations. The relationship between aeration-dependent microbial activity and soil water content facilitates evaluating the indirect effects of soil management practices, such as tillage, on microbial activity.

The trend in erosion prediction technology in the USA, Australia, and Europe is toward the development of process-based simulation models. The emphasis in erosion research on strictly empirically based models, such as the Universal Soil Loss Equation, is declining. With the process-based technologies come a new array of research needs. In the USA, The USDA Water Erosion Prediction Project (WEPP) has produced a new generation of soil-erosion prediction technology based on fundamentals of hydrologic and erosion science. The development of the new computer-based WEPP erosion model for estimation of rill and interrill erosion required an extensive review and analysis of current knowledge of the science of soil erosion by water. Research needs were identified. The relative importances of identified research needs were evaluated using a sensitivity analysis of the WEPP model, which identified the more important of the input variables required to execute the model. The review of research reported here, along with a discussion of associated current needs for research, addresses four general areas: (i) fundamental erosion relationships, (ii) soil and plant parameters related to erosion, (iii) data bases, user interfaces, and conservation system design, and (iv) erosion model development and analysis.

This study tested the hypothesis that the effects of erosion on water storage and wheat (Triticum aestivum L.) yield could be partially alleviated by applying appropriate fertilizers. Two sites were used, one on Rexburg silt loam, a coarse-silty, mixed, frigid Calcic Haploxeroll, and the other on Newdale silt loam, a coarse-silty, mixed frigid Calciorthidic Haploxeroll. Topsoil-depth treatments were +15, 0, -15, or -30 cm changes relative to the original surface. After making the soil depth changes, 54 kg P ha-1 were incorporated on one half of each topsoil depth plot and the other half received no P. These P or no P plots were split for applications of 0, 34 or 68 kg N ha-1. Phosphorus had no effect on wheat yield. Without fertilizer N, yields on -15 and -30-cm plots were reduced 46 and 55%, respectively, but increased 69% from the addition of 15 cm of topsoil, compared with the 0-cm plot. Removing 15 and 30 cm of topsoil also reduced the upper limit of N-fertilized production to 80 and 65%, respectively, of production on undisturbed N-fertilized plots. Three kilograms fertilizer N ha-1 each crop year offset each centimeter of soil removed, but only to the new lower production limit. All plots had similar amounts of stored, available soil water in the spring, but a large fraction of this water remained unused at harvest on plots with 15 and 30 cm of topsoil removed because the low-yielding wheat did not use as much water. Profile water differences at harvest were no longer apparent by the next spring, following winter recharge. Unused water at harvest, which partially filled the soil profile, reduced winter infiltration and contributed to subsequent runoff from precipitation on those plots. Adding N fertilizer was only a partial solution to topsoil deficiencies.

Soybean [Glycine max (L.) Merr.] yields from severely eroded sites in these soils are about half of those from slightly eroded sites. Most of the severely eroded sites are on the Pacolet soil series (clayey kaolinitic, thermic, Typic Kanhapludult), which is shallower to the bottom of the Bt horizon. Differences in infiltration rates may cause these differences in yield. Our objectives were to quantify infiltration rate differences between Cecil and Pacolet soils and to determine the reason for the differences. Infiltration rate was measured using a cylinder infiltrometer at five sites with adjacent Cecil and Pacolet soils, and using a sprinkler infiltrometer at one site. Steady-state infiltration in the Pacolet was significantly lower than in the Cecil, 4.2 and 30.1 mm h-1, respectively. Cecil infiltration rates increased as depth to the Bt horizon increased. On Cecil, final sprinkler infiltration rate was 61.1 mm h-1 with a sod surface, but surface sealing reduced infiltration with a bare surface to 3.6 mm h-1 within 1 h. The final sprinkler-infiltration rates of the Pacolet soil were 4.5 mm h-1 for sod and 4.2 mm h-1 for bare surfaces. Pacolet infiltration rates were controlled by the Bt1 layer, which had a lower, saturated hydraulic conductivity (2.3 mm h-1) and fewer mesopores than adjacent horizons but was similar to the upper Bt of the Cecil soil. The Cecil soil's limiting Bt1 horizon occurred much deeper in the profile and had less effect on infiltration. Areas of Pacolet within the Cecil landscape, too small to map separately, can cause increased runoff and variability of yield potential of areas mapped as Cecil.

This study was conducted to identify the effect of tillage intensity associated with soybean [Glycine max (L.) Merr.] and grain sorghum [Sorghum bicolor (L.) Moench] crop sequences following winter wheat (Triticum aestivum L.), and the effect of summer crop species on selected physical characteristics of a Cecil sandy loam (clayey, kaolinitic, thermic Typic Kanhapludult). Through eight seasons, soybean and grain sorghum were grown in 10 crop sequences that were imposed on three tillage treatments: conventional tillage (CT), in-row chisel (MT), and no-tillage (NT). Following summer crop harvest in the eight season, aggregate stability, organic C, bulk density, air-filled pore space, particle-size distribution, and infiltration of water were measured. Aggregate stability at 0 to 10 mm was significantly higher for MT and NT than for CT. The CT treatment exhibited significantly lower bulk density and higher air-filled pore space than MT and NT. Infiltration was significantly greater on the MT than the CT and NT treatments. Greater aggregate stability, higher air-filled pore space, and lower bulk density were measured after two or more years of grain sorghum than after soybean. The maintenance of wheat straw on the soil surface under the MT and NT treatment exhibited an effect to a depth of 75 mm and the in-row chisel treatment affected infiltration. Crop-rotational effects can be erased or modified by tillage and may only be observed under NT. Grain yield response of soybean and grain sorghum to changes in soil physical characteristics, as a consequence of crop sequence and tillage, may need to be interpreted in relation to crop species and cropping sequence.

This is sufficient accuracy to locate sampling areas identified with Systeme Probatoire d'Obervation de la Terre (SPOT) satellite imagery (pixel resolution of 30 m), but not for locating smaller sampling areas, such as those identified in low-altitude photographs.

The coupled gin stand and lint cleaner unit is designed to replace one gin stand and two stages of standard saw-type lint cleaning. Raw fiber data from both a small laboratory study and a full-scale mill study show that the coupled lint cleaner, when compared to standard lint cleaning, produces fiber that is significantly cleaner, longer, and with fewer short fibers. Spinning and weaving data also show that the coupled-lint-cleaner fiber has significantly less mill waste and a tendency to produce more uniform yarn and stronger, more uniform cloth.

As groundwater storage continues to decline, the common practice of "heavy" water application to fully wet the root zone of graded furrow fields prior to planting is being questioned. Under some conditions, preplant irrigation is an essential practice for timely stand establishment and high yields. However, in many situations, the large application depths required for surface irrigation result in inefficient soil water storage and low yield response. With center pivot sprinkler systems, smaller and more precise preplant irrigation application amounts are possible resulting in more efficient preseason storage. We conclude that the benefits of preplant irrigation are likely to be greatest (1) when the soil profile is dry before planting; (2) when seasonal irrigations are not applied to drought-tolerant crops or are reduced in amount; (3) when early planting limits soil wetting by precipitation by the desired date; and (4) when preplant irrigation plus seasonal precipitation on deep, high water storage soils can result in moderately high irrigated yields without seasonal irrigation. The benefits are likely to be low (1) when soil profiles are moderately wet at time of irrigation; (2) when planting dates are flexible and can follow precipitation events for stand establishment; and (3) when seasonal irrigation provides adequate water to meet plant requirements. As groundwater decline continues and precipitation becomes more important for supplying crop water requirements, the use of preplant irrigation as an irrigation water management practice will likely decline in importance in the High Plains.

Runoff and seep detectors were designed as water-activated, printed-circuit switches connected to a programmable data logging system to indicate and distinguish when seepage and runoff had occurred at the soil surface. The results from the runoff and seep detectors predicted the seep area indicated by measured water potential well. Seepage and overland flow following storms on the 21.3-m (70-ft) cross-section expanded the variable source area up to 15.2-m (50-ft) from the stream which decreased to within 6.7-m (22-ft) of the stream within two days after the end of the storm. Localized precipitation, applied only to the cross-section via sprinkler irrigation under a similar water potential distribution, caused equivalent source area expansion which decreased to the 6.7-m (22-ft) area in only 16 h. This 6.7-m (22-ft) source area exhibited seepage and seepage overland flow in both cases for five to seven days after the precipitation event. The extent of the variable source area was shown to be dependent on the antecedent moisture of the entire hillslope as well as the amount and areal extent of precipitation.

The profiler provides a convenient, non-contact means of accurately determining surface roughness parameters. Surface elevations were measured to evaluate changes in random roughness of three tillage treatments (chisel plow, moldboard plow, and field cultivator) with simulated rainfall. Random roughness decreased with rainfall. Consolidation of 30 to 50 mm occurred on all three treatments. Horizontal soil movement occurred on the chisel and moldboard treatments from the tillage tool ridges to the furrows. A decrease of approximately 60 mm of total relief was observed with soil lost from the ridges being deposited into the furrow. However, no such movement was observed in the field cultivator treatment. These results were consistent with earlier results obtained using a manually operated profiler.

GPR images of the field site were produced at six transects before and after irrigations. Application uniformity was carefully monitored and application uniformity curves were created for each of the transects. The radar images reliably detected wetting front movement in the soil profile and the wetting front shapes markedly resembled the application uniformity curves. Water content data obtained from soil samples supported the wetting front movement observed on the GPR charts. Statistical analysis showed a link between the GPR reflection bands and the wetting front as identified by the water content measurements.

Methods to estimate RR decay are needed for computer models which simulate physical processes occurring at or near the soil surface. The objective of this study was to estimate RR decay curves as a function of soil properties. Surface roughness has been reported for selected soils before and after simulated rainfall (5 to 80 mm on five soils, 35 to 300 mm on one soil) and before and after natural rainfall (7 to 350 mm on two soils). The soils represent a wide range of textural and physical properties. A modified exponential function was fit to normalized RR values (RR after rainfall/initial RR) using rainfall amount as an independent variable. The coefficients of this function were then approximated as a function of two soil properties: percentage organic carbon and percentage clay. Surface stability increased with greater amounts of organic carbon. Surface stability increased with clay content to about 31% and then decreased with greater amounts of clay. Random roughness decay curves may be estimated for specific soils by using the exponential function. RP POTTER, KN (reprint author), USDA ARS,SOIL SCI,TEMPLE,TX 76503, USA.

We analyzed the Wind Energy Resource Information System data to determine scale and shape parameters of the Weibull distribution for each of the 16 cardinal directions for each month at 704 locations in the United States. We also summarized wind direction distributions, ratio of daily maximum to daily minimum wind speed, and hour of maximum wind speed by month for each location. This summary of historical wind statistics constitutes a compact data base for wind simulation. Equations were formulated and procedures developed and used with the compact data base and a random number generator to simulate wind direction and sub-hourly wind speed. Cumulative wind speed distributions, calculated from the Weibull parameters, and wind speeds simulated at one-hour intervals for 1000 days agreed well. The model reflects historical day-to-day wind variation and wind speed variations within a day. It will be useful to those needing wind speed and wind direction information and will provide the wind simulator requirements in a wind erosion prediction system.

In this study, a water management model (PREFLO) was developed which could be used to simulate unsaturated and saturated movement of water in a soil profile in which preferential flow might occur. PREFLO is based on a one-dimensional finite difference solution to the Richards equation with a nonuniform grid spacing. Large pores are described on a macroscopic scale with vertical movement of water computed from the equation for flow in a capillary tube. Water moving from the large pores into the soil matrix via horizontal infiltration is added to the sink term in the Richards equation. Example simulations indicated that PREFLO can be a useful tool in simulating the timing, frequency, and volume of preferential flow in a soil profile. Use of hourly rainfall data and the Richards equation to simulate soil water conditions allowed the PREFLO model to predict preferential flow when infiltration into the soil matrix was limiting. Simulated water table response in soils that contain preferential flow channels was shown to be dependent on hydraulic conductivity and the number of large pores. For a simulated rainfall event on a soil with a hydraulic conductivity of 0.15 cm/h, PREFLO predicted a rapid rise of the water table caused by water ponding in the large pores.

It also decreased when environmental temperature was low (16-degrees-C below the control). Approximately 75% of eating activity and feed consumption occurred in daytime hours (0700-1900). Eating activity was greatest from 0701 to 0900 and 1301 to 1600 hours. There was no apparent change in the daily eating pattern with age. Temperatures 8 and 16-degrees-C below control treatment temperature, respectively, caused 8.6% and 18.9% reduction in gain and 14.8% and 29.6% increase in feed intake.

One important requirement of a computer grading system is that it be able to locate the longissimus dorsi (l.d.) muscle in a scene containing an image of the exposed surface of the carcass' 12th rib. Characteristics of the l.d. are important in determining both the yield and quality grades. Previously developed image processing methods have been successful in segmenting the loin eye area, but the results tend to include extraneous muscle tissue not part of the l.d. This article presents two image processing algorithms for separating these non-l.d. components. Both are based on the assumption that the scene can be modeled as a union of overlapping convex sets, and both are implemented using mathematical morphology. The first algorithm is a modification of one proposed by Meyer (1979) to separate overlapping convex blobs. The second uses a morphological opening to destructively remove external portions. Both methods were found to perform adequately when tested on 30 images of beef carcass ribeyes. RP MCDONALD, TP (reprint author), USDA ARS,MEAT ANIM RES CTR,BIOL ENGN UNIT,CLAY CTR,NE 68933, USA.

Density increases along main skid trails yarded by tractor and on the landing exceeded 15 percent over natural bulk density. Soil displacement on areas adjacent to skid trials, fire lines, and the landing was greater with Caterpillar tractor yarding than rubber-tired skidder yarding.

The experiment was performed at zero windspeed, with zero slope and uniform fuel particle size. Major revisions include the propagating flux ratio, the reaction velocity, and the moisture damping coefficient. These parameters remain functions of the observable fuel bed variables. Also, we redefine or reinterpret many of the fuels' descriptive parameters such as the net loading, the heat of combustion, fuel bed bulk density, flame residence time, and heat of ignition. As before, spread rate is based on an energy balance ratio of power source and heat sink terms. We use Frandsen's (1973) formulation for effective bulk density to account for that fraction of the fuel bed that must be raised to ignition temperature. The enthalpic load of ignition also includes the energy required for complete pyrolyzation of the fuel as reported earlier. We also use Susott's (1984) method of determining the "flaming" heat of combustion, thus separating the gaseous and carbonaceous mass fractions of pyrolysis. This provides that the heat of combustion will account for many of the physiochemical effects of minerals, and so on, on the production rate of the gaseous fuel. Thus the reaction intensity is of the flames alone and specifically excludes energy derived from burning char whether in the flaming zone or not. It is still measured as an energy density within the combustion zone. In this new formulation, moisture damping is completely divorced from fire extinction. Fire extinction is properly handled by a probability function acting on the reaction velocity. Moisture damping is a simple, negative exponential function of the fuel moisture, wherein each fuel sample has a characteristic moisture content. In the experiment, the characteristic fuel moisture was dependent only on the size of the fuel particles; however, it is further shown that it will vary greatly with the physiology of different fuels (bark covered, live or fresh-fallen foliage, decayed wood, and so on). The formula for reaction velocity begins with Anderson's 8d (1985) rule-of-thumb, which provides that the burning residence time in minutes is equal to eight times the fuel particle thickness in inches. The burning rate is limited by the free path for radiation or heat flux to propagate through the fuel bed, and further restricted by limiting the effect of excessive fuel loading or bed depth. A probability function shuts the fire down at very light fuel loads or high fuel moisture content as previously reported. The concept of optimum packing ratio is abandoned. Following Rothermel, the propagating flux is some fraction of the reaction intensity, empirically formulated as the propagating flux ratio. It is an elementary function of the free optical path through the fuel bed. Procedure is outlined whereby the manager in the field may estimate the probabilities that his real fire behavior will depart from the prediction.

While yields may be highest with very intensive site preparation and planting, lower cost methods are effective, and economic returns associated with them can be quite attractive. An internal rate of return of 10.8 percent after taxes and inflation can be obtained from natural regeneration with some control of competition at harvest plus a program of prescribed burning. Using similar vegetation control measures and planting seedlings increases wood yields, and the associated rate of return is 10.1 percent.

Known numbers of seeds of seven weed species were added to the native seed population at the beginning of the study. Plots were nontilled or tilled to depths of 0, 5, 10, and 15 cm early in the spring of each year. Velvetleaf, spurred anoda, hemp sesbania, morningglory species, and pigweed species emergence was significantly greater from the nontilled plots during the first year after seeds were added to the native seed population. Tillage, regardless of depth, reduced weed emergence during the first year where seeds were added to the plots but had no effect on emergence from plots where no seeds were added. Tillage during the second through the fifth year did not affect emergence regardless of the addition of seeds. Of the 5-yr emergence totals, 61 to 88% of all weeds in all plots emerged during the first year and 9 to 23% emerged during the second year. The 5-yr decline rate for emergence of all weeds was exponential. Viable seeds of prickly sida, spurges, and pigweeds in the nontilled plots declined from 590, 1531, and 4346 m-2, respectively, to zero by the third year. Tillage did not affect the decline. However, weed emergence in the field indicated that a few (1.0 to 5.6 m-2) seeds of those weeds were still viable after 3 yr. In nontilled plots, many recently added seeds were on or near the soil surface and germinated during the first year. Tillage moved many seeds to sites that were unfavorable for germination and emergence during the first year. C1 USDA ARS,WATER QUAL & WATERSHED RES LAB,DURANT,OK 74702.

Differences in weed competitiveness within the 100-cm area of influence were induced by dates of soybean planting, locations, weed species, and years. Soybean yield losses within the first 20-cm interval from weeds correlated well with yield of all soybean plants within 100 cm of weeds (r2 = 0.86). Soybean growth responses as a function of distance from weeds were best described by complex polynomials, but simple linear functions, based on a data point from soybean plants nearest a weed and from the average of plants 60 to 100 cm from a weed, closely approximately actual yield losses (r2 = 0.96). Soybean yield losses were highly correlated (r2 = 0.84) with leaf area of weeds as viewed from directly above the weed-crop canopy. Weed canopy diameter, measured from overhead photographs 8 weeks after soybean emergence, also correlated well with soybean yield losses (r2 = 0.82), but correlation with actual weed leaf area was not significant (r2 = 0.31).

Corn fresh weight was reduced by postemergence application of thifensulfuron when applied at 180 g ai ha-1 without surfactant or at 18 g ha-1 with a nonionic surfactant. Corn was more susceptible to root exposure whereas velvetleaf was more susceptible to foliar exposure. Velvetleaf was most susceptible when plants were young, when a nonionic surfactant was added, and at 20 rather than 30 C. Simulated rainfall 8 h after application reduced velvetleaf injury by thifensulfuron at 18 g ha-1 without surfactant; however, with addition of a nonionic surfactant, velvetleaf injury was reduced only if rainfall occurred less than 2 h after application.

Glyphosate (2.2 kg ai ha-1) and picloram (2.2 kg ae ha-1) killed more than 88% of larkspur plants in both vegetation types. Clopyralid and triclopyr were ineffective at comparable rates. Metsulfuron (88 and 138 g ai ha-1) provided variable control. Glyphosate is nonselective and killed all perennial vegetation, except for Thurbers fescue and mountain brome in the aspen type. Picloram applied at 4.5 kg ha-1 suppressed grasses on the subalpine site, but allowed grasses to increase at lower rates. All herbicides reduced forb cover. C1 UTAH STATE UNIV,LOGAN,UT 84322.

Withholding irrigation for 10 to 14 days before herbicide application did not reduce control of green foxtail with normal use rates of herbicides if plots were irrigated at the time of application.

Seeds of 47 species belonging to 13 families (Asteraceae, Boraginaceae, Dipsacaceae, Euphorbiaceae, Fabaceae, Fumariaceae, Lamiaceae, Liliaceae, Poaceae, Polygonaceae, Resedaceae, Rosaceae, and Solanaceae) were found to have elaiosomes, indicating that these species are probably mymecochorous, i.e., dispersed by ants. These include important rangeland weeds such as bull thistle, Canada thistle, musk thistle, diffuse knapweed, spotted knapweed, and leafy spurge. Myrmecochory in naturalized species may enhance their weediness in areas where they are established and assist their colonization of new and relatively closed communities.

Protein antigens from elementary bodies of TT3 were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and transferred electrophoretically to nitrocellulose before being probed with plasma or synovial fluid from TT3-inoculated birds. The major outer-membrane protein (MOMP), the 60,000-molecular-weight proteins, and a 97,400-molecular-weight protein were the predominant antigens recognized by IgG in the plasma and joint fluids. Plasma IgG specific for the 97,400 protein band was first detectable at day 10 postinoculation(PI). Antibodies to the 60,000-molecular-weight protein and MOMP were first detected at days 14-17 PI and at days 7-10 PI, respectively, in some birds, and as late as days 36-42 PI and days 42-70 PI in others. The antibodies were still present at day 142 PI. Immunoblotting techniques indicated that the antigens to which these antibodies were reacting were protein. These observations may have implications for the development of serodiagnostic assays as well as the identification of potential proteins for subunit immunogens in birds.

Four of these isolates were also tested after extensive serial passage in chicken embryo fibroblast cultures. Observations were made on replication in vitro and in vivo, pathogenicity by in ovo inoculation, antigenicity, and protection against virulent MDV challenge. Among the low-passage isolates, there were some differences in pathogenicity after in ovo inoculation but relatively little difference in other characteristics, with the exception of the HN-1 strain, which replicated more rapidly in cell culture but produced generally lower in vivo responses than other isolates. After extended in vitro passage, isolates replicated much more readily in cell culture and produced lower pathologic responses in vivo than low-passage isolates, as has been reported for serotype 1 isolates. No antigenic differences among isolates were detected, but high-passage isolates induced lower levels of precipitating antibodies than low-passage isolates, indicating a possible reduction in A antigen production. The observed diversity associated with strain and passage level may be of value in the selection of optimum vaccine strains.

Vaccine efficacy based on hemagglutination-inhibition (HI) titers was comparable to that of control mineral oil vaccines. Tissue reaction to intramuscular injection of the terpene oil emulsion vaccines was greatly reduced 3 weeks post-vaccination compared with that of mineral oil-based vaccine. Viscosity of the terpene oil vaccines was satisfactory but increased three to four times that of mineral oil vaccine when the antigen phase volume increased from 5% to 20%.
