W64A x A619) kernels. The endosperm contained the highest proportions of each activity on a per tissue basis. In the endosperm, NADH-GOGAT and Fd-GOGAT activities increased 12- and 2.5-fold, respectively, during early zein accumulation. NADH-GOGAT and Fd-GOGAT activities were expressed in the upper, middle and lower portions of the endosperm in a manner that paralleled but preceded zein accumulation. Maize endosperm NADH-GOGAT was purified 159-fold using ammonium sulfate fractionation, anion exchange chromatography and dye-ligand chromatography. Apparent K(m) values for glutamine, alpha-ketoglutarate and NADH were 850, 19 and 1-mu-M, respectively. The results are consistent with endosperm GOGAT functioning to redistribute nitrogen from glutamine, the predominant nitrogenous compound delivered to the endosperm, into other amino acids needed for storage protein synthesis.

All highly virulent field strains studied to date have proven tolerant of and able to metabolize rishitin. Preliminary genetic analysis of one potato-pathogenic field strain, R-6380, suggested that multiple loci might confer rishitin metabolism and that not all of these loci are associated with virulence (A. E. Desjardins and H. W. Gardner, Mol. Plant-Microbe Interact. 2:26-34). To investigate these hypotheses, four phenotypically unique meiotic products of a tetratype ascus from a backcross to strain R-6380 were crossed to strains that were low in rishitin tolerance, rishitin metabolism, and virulence. Tetrad progeny from all four crosses were analyzed for these traits. This genetic analysis indicated that rishitin metabolism in strain R-6380 is controlled by genes at two or more loci but that high virulence on potato is associated with only one of these loci, designated as Riml.

Conidia produced in 5:1 medium were longer and thinner than conidia from 15:1 and 40:1 media, and a higher proportion contained two, rather than one, nuclei per conidium. After either 6 or 12 hr on cellophane membranes, a greater proportion of conidia produced in the 5:1 medium had germinated compared with conidia from 15:1 and 40:1 media. Germination on attached leaves of Sesbania exaltata was greatest with conidia from 5:1 medium when assayed after either 6 or 24 hr. Equality of variance tests implied that the leaf environment had a greater influence on the germination of conidia from 15:1 medium than conidia from 40:1 or 5:1 media. All conidial treatments caused losses in biomass of seedlings of S. exaltata. Conidia produced from 5:1 or 15:1 media induced greater reduction in shoot height, and conidia from 5:1 medium induced greater reduction in shoot dry weight than did conidia from 40:1 medium. Further research on increasing the efficacy of mycoherbicide conidia by modifying the phyllosphere environment and the nutritional conditions of the conidiation medium is needed.

Highly activated enzyme, in desalted crude leaf extracts prepared from illuminated leaves, was inactivated in vitro in a time- and ATP-dependent manner. Partial purification of SPS by polyethylene glycol fractionation and Mono Q chromatography yielded enzyme that was not ATP-inactivated, possibly due to elimination of contaminating protein kinase. We used the partially purified SPS as substrate to identify an endogenous protein kinase. The protein kinase catalyzed the time- and ATP-dependent inactivation of SPS, and the apparent K(m) for Mg.ATP was estimated to be approximately 10-mu-M. The partially purified maize SPS protein was phosphorylated in vitro using [gamma-P-32]ATP and either the endogenous protein kinase or the catalytic subunit of cAMP-dependent protein kinase. The incorporation of radiolabel was closely paralleled by inactivation of the enzyme. These results provide the first evidence for regulation of maize leaf SPS by protein phosphorylation, which we postulate is the mechanism of light-dark regulation in vivo.

The catalytic activity of the inactivated enzyme (dark form or in vitro inactivated form) was strongly stimulated by high ionic strength in the assay mixture and at 0.4 M KCl reached activities similar to those obtained from illuminated leaves. Numerous salts were effective, but for most studies, 0.3 M KCl was used. The salt-stimulation of enzyme activity was rapid and readily reversible and was antagonized by the presence of ethylene glycol in the assay. The presence of salt was also found to reduce the IC50 (concentration required for 50% inhibition) for p-chloromercuribenzenesulfonic acid. We postulate that phosphorylation of maize SPS induces a conformational change in the protein (that affects both maximum catalytic activity and sensitivity to P(i)) either through electrostatic or hydrophobic interactions which are affected by high ionic strength. Salt stimulation of the deactivated enzyme extracted from darkened leaves was observed for a variety of C-4 plants, but not for any of the C-3 species tested.

Bean plants were either left non-inoculated (controls) or were inoculated with the vesicular-arbuscular mycorrhizal (VAM) fungus Glomus etunicatum or a strain of Rhizobium leguminosarum bv. phaseoli (UMR-1899). Plants from the Mexico 309 cultivar maintained a higher growth rate, supported proportionately more nodules and mycorrhizae, and assimilated relatively more N or P when colonized by Rhizobium or Glomus, respectively, than did plants of the Rio Tibagi cultivar. Estimated specific nodule activity for Mexico 309 beans was more than twice that of Rio Tibagi, whereas the specific phosphorus uptake rate (SPUR) was 35% greater in the non-inoculated roots of Rio Tibagi compared to Mexico 309. Colonization by G. etunicatum more than doubled the SPUR for each cultivar compared to control roots. New acid phosphatase isozymes appeared in VAM-colonized roots of both cultivars compared to controls. Acid and alkaline phosphatase activities were significantly higher in G. etunicatum-colonized Mexico 309 roots, but not in Rio Tibagi mycorrhizae, compared to uninfected roots. Polyphosphate hydrolase activity was elevated in mycorrhizae of both cultivars compared to control roots. These results indicate that the dependence of a host on a specific endophyte increases when there are limitations to the supply of a nutrient that the endophyte can provide. The greater the increase in absorption or utilization capacity following colonization by the microsymbiont, the greater the dependence by the host. More importantly, identification of enzymatic activities that influence these plant-microbe associations opens the possibility that the specific genes that code for these enzymes could be targeted for future manipulation.

Bean plants were either inoculated with a strain of Rhizobium leguminosarum bv. phaseoli (UMR-1899), a vesicular-arbuscular mycorrhizal (VAM) fungus (Glomus etunicatum) or were left non-inoculated (controls). At two harvests (21 and 28 days post-emergence), extracts containing soluble proteins and free amino acids were prepared from leaves, roots and nodules of field beans. Nodulated plants contained a significantly higher concentration of protein and amino acids in all plant parts. Nitrogen-fixing beans invested a significantly greater proportion of total N as protein-N and amino acid-N as compared to VAM or control beans. Abundant nodule-specific proteins (nodulins) were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), identified and quantified using scanning densitometry. Rio Tibagi nodules contained a significantly lower concentration of glutamine synthetase (GS) subunits than did Mexico 309 nodules. Glutamate synthase (GOGAT) and GS activities were low relative to other legumes. The transferase/synthetase ratio for GS was also low indicating that the synthetase activity was saturated and was operating at maximal level in these young N2-fixing associations. Specific nodule activity (SNA) and the level of GS were correlated (r = 0.90, p < 0.05) for both cultivars at both harvests. GS activity was only 8 or 24% higher than SNA in nodules of Mexico 309 or Rio Tibagi cultivars, respectively, under conditions where substrate was not limiting. This suggests that early in the functioning of this symbiosis N assimilation by GS is the rate-limiting step in N2 fixation by these two bean cultivars, each with a different symbiotic efficiency. Phaseolus breeding programs that attempt to improve N2 fixation in beans should identify germplasm that expresses elevated levels of nodule-specific GS or GOGAT, and this material should be used along with effective R. leguminosarum bv. phaseoli strains that have already been selected, to determine superior host-microsymbiont associations.

These methods varied from the measurement of effects of disease on components of yield to calculation of area of symptoms on certain leaves at different growth stages. We analyzed data from a uniform group of wheat entries in the USDA Septoria nursery that had been grown in seven locations in North America and Europe during the years 1982-1987. Symptom severity and height of symptom on the plant were compared to kernel number and kernel weight. Location, year-within-location and genotype were also considered. In the context of this study, we concluded that location, and year-within-location are the most important factors determining yield reduction (as measured by relative kernel weight). Selection directly for components of yield is quite effective, but selection by means of disease symptoms is often not correlated with yield. We also conclude that specific methods for relating symptoms to yield reduction that are applicable to a particular location are probably useful and appropriate for that location only.

An antibody raised against a cytoplasmic loop region of connexin43 cross-reacted strongly with a cell wall-associated polypeptide (possibly a doublet) of 26 kilodaltons. Indirect immunogold labeling of thin sections of mesocotyl tissue with this antibody labeled the plasmodesmata of cortical cells along the entire length of the plasmodesmata, including the neck region and the cytoplasmic annulus. Sections labeled with control preimmune serum were essentially free of colloidal gold. An antibody against connexin32 cross-reacted with a 27-kilodalton polypeptide that was present in the cell wall and membrane fractions. Indirect immunogold labeling of thin sections with this antibody labeled the plasmodesmata mainly in the neck region. It is suggested that maize mesocotyl plasmodesmata contain at least two different proteins that have homologous domains with connexin proteins.

Proteins were then extracted from root tips of both cultivars, separated by 2D-PAGE, and quantified using computer analysis of gels. The objective of the work was to determine if the major changes in protein expression associated with Al stress were cultivar-specific, if the changes correlated with Al tolerance, and if they occurred in a specific fraction of cell proteins. Of the approximately 600 proteins examined, 14 cytoplasmic proteins and eight microsomal proteins were induced or enhanced by Al treatment in one or both cultivars, while nine cytoplasmic and 12 microsomal proteins were diminished or repressed. Among the 43 proteins significantly altered by Al treatment, three cytoplasmic proteins, and no microsomal proteins, were induced or enhanced solely in the Al-tolerant cultivar. Al affected the programme of formation of both cytoplasmic and microsomal proteins, but appeared to cause the greater change in proteins associated with the cytoplasm. The results indicate that most of the changes in protein expression associated with Al stress probably result from effects of Al on cell metabolism, and that only a few proteins may be induced or enhanced as part of a cultivar-specific mechanism of Al tolerance.

Benzyl-adenine and gibberellin enhanced juvenile characteristics; in general, more runners and monofoliolate leaves were produced, net photosynthesis was reduced, leaf diffusive resistance was increased and, on occasion, flowering was delayed. In contrast, abscisic acid and a gibberellin biosynthesis inhibitor, paclobutrazol, resulted in a more adult phenotype; specifically, flowering was earlier, net photosynthesis and leaf diffusive resistance rates were equal to those of adult plants, and fewer leaves were monofoliolate. Tissue culture-produced plants reacquire the adult phenotype earlier than seedlings mature. Abscisic acid application to seedlings also resulted in earlier and increased flowering. Endogenous abscisic acid concentrations were greater in adult plants and less in tissue culture and seedling plants at 3 and 7 weeks ex vitro, after germination or after adult runner propagation. No flowering occurred at 3 weeks in any propagation type and only runner-produced plants flowered at 7 weeks. At 15 weeks, no statistical difference in abscisic acid concentrations existed among propagation treatments and all propagation types flowered. The endogenous concentrations of abscisic acid in plants propagated by all three methods were much higher at three weeks compared to concentrations at 7 or 15 weeks.

In contrast to BGMV isolates from Central America and the Caribbean, BGMV-BZ could not be sap-transmitted to beans. Cloned geminiviral DNA components were used as DNA probes for the rapid and specific detection of BGMV-BZ and three sap-transmissible bean-infecting geminiviral isolates-BGMV from Guatemala (BGMV-GA) and the Dominican Republic (BGMV-DR) and bean dwarf mosaic geminivirus from Columbia (BDMV-CO). A general DNA probe detected all four viral isolates, whereas specific probes detected BGMV-BZ, BDMV, or BGMV-GA and BGMV-DR. Nucleic acid dot and squash blot methods were used to prepare samples for hybridization, and the dot blot method was used to determine relative differences in viral nucleic acid titers in infected bean leaves. The general and specific probes were employed to study the variability of BGMV isolates and potential weed reservoirs of geminiviruses in the Dominican Republic.

The percentage of trees infected increased over this period, as did the number of infections on 79% of the trees that were infected in 1981. However, few of the infected trees had three or more infections and only eight trees had 10 or more infections by 1987. The probability of a tree being infected was significantly greater if the tree was in the understory before logging rather than having become established in the understory after logging. There was no significant orientation by distance or direction of infected trees from the infected residual trees. Infections were significantly concentrated in interior portions of the lower crown. From 1981 to 1987, infected hemlock trees grew an average of two times greater in height than the dwarf mistletoe advanced upward in their crowns. The low number of infections on these trees, their concentration over time in interior portions of the lower crown, the sparsity of witches'-brooms, the rapid increases in tree height after thinning, and the common interspersion of resistant Sitka spruce trees all indicate that there is little likelihood of damaging disease levels developing in thinned stands on high quality sites within the planned 90- to 120-yr rotation.

The accessions from the U.S. Department of Agriculture's Plant Introduction (PI) Collection had been selected based on resistance to bacterial wilt. Resistance in one of these seven S3 families was significantly greater than that of the parents. The survival curves were plotted for 21 days after inoculation of 3-wk-old seedlings with a broth culture of Pseudomonas solanacearum, based on time from inoculation to initial wilt symptoms for plants grown in a greenhouse at temperatures of 33-37 C in daytime and 24-27 C at night. Significant differences were found in the survival curves of parental PI lines and their corresponding F3 families of all four crosses in the hybridization program. Resistance in three of the four families was significantly improved over levels expressed by the parents. Levels of resistance that equalled the most resistant parent were found in the fourth family. Both crossing and selfing of resistant eggplants offer promise in developing lines with improved bacterial wilt resistance.

Mean percentage of stem girdling, lesion area, and relative lesion area were similar on stems inoculated with soil-agar blocks containing seven to 100 chlamydospores or inoculated with 1,000 zoospores. Foot rot severity ratings were significantly higher when inoculum consisted of 0.5-cm-diameter mycelial agar disks compared with chlamydospores or zoospores. Commercial rootstocks known to be moderately resistant to or with field tolerance to foot rot were rated as susceptible when mycelial agar disks were used as an inoculum source. The use of quantifiable inoculum sources such as chlamydospores or zoospores may allow evaluation of rootstocks with intermediate levels of resistance to foot rot.

The ester formulation of diclofop, at 0.2 micromolar, completely inhibited root growth in herbicide-susceptible oat (Avena sativa L.) after a 96 hour treatment, but induced only a delayed transient depolarization of the membrane potential in oat root cortical cells. Root growth in susceptible maize (Zea mays L.) seedlings was dramatically reduced by exposure to 0.8 micromolar diclofop-methyl, while the same diclofop-methyl exposure hyperpolarized the membrane potential within 48 hours after treatment. Furthermore, exposure of maize roots to the protonophore, carbonyl cyanide m-chlorophenylhydrazone (CCCP) (50 nanomolar), inhibited growth by only 31%, 96 hours after treatment, while the same CCCP exposure depolarized the resting potential by an average of 32 millivolts. Thus, the protonophore hypothesis cannot account for a differential membrane response to phytotoxic levels of diclofop-methyl in two susceptible species. From the results of others, much of the evidence to support the protonophore hypothesis was obtained using high concentrations of diclofop acid (100 micromolar). At a similar concentration, we also report a rapid (3 minute) diclofop-induced depolarization of the membrane potential in roots of susceptible oat and maize, moderately tolerant barley (Hordeum vulgare L.), and resistant pea (Pisum sativum L.) seedlings. Moreover, 100 micromolar diclofop acid inhibited growth in excised cultured pea roots. In contrast, 100 micromolar diclofop-methyl did not inhibit root growth. Since the membrane response to 100 micromolar diclofop acid does not correspond to differential herbicide sensitivity under field conditions, results obtained with very high levels of diclofop acid are probably physiologically irrelevant. The results of this study suggest that the effect of diclofop-methyl on the membrane potentials of susceptible species is probably unrelated to the primary inhibitory effect of the herbicide on plant growth.

The hypernodulating soybean mutants were shown to accumulate higher root concentrations of isoflavonoid compounds (daidzein, genistein, and coumestrol) and to be more extensively nodulated than was the Williams parent when inoculated with B. japonicum. The hypernodulating mutants and the parent line, williams, also showed decreased isoflavonoid concentrations and decreased nodule development if N was applied. The current study evaluated the effect of localized NO3- application on root isoflavonoid concentration and on nodulation in split-root systems of the Williams wild type and a hypernodulating mutant (NOD1-3). Nitrate application markedly decreased isoflavonoid concentrations in non-inoculated soybean roots. When roots were inoculated, nodule number, weight, and nitrogenase activity were markedly suppressed on the root-half receiving 5 millimolar NO3- compared with the other root-half receiving 0 millimolar NO3-. High performance liquid chromatographic analyses of root extracts showed that the root-half receiving 5 millimolar NO3- was markedly lower in isoflavonoid concentrations in both soybean lines. This was partially due to the localized stimulatory effect of NO3- on root growth. The inoculated NOD1-3 mutant had higher isoflavonoid concentrations than did the Williams control in both the presence and absence of NO3-. These results provide evidence that the site of N application primarily controls the site of nodulation inhibition, possibly through decreasing isoflavonoid levels. Although the effect of NO3- on nodule development and root isoflavonoid concentration was strongly localized, there was evidence that NO3- also resulted in a systemic effect on root isoflavonoids. The results are consistent with previous speculation that internal levels of root isoflavonoids may affect nodule development.

Two lines of Lemna gibba were tested for uptake of [N-15-indole]-labeled tryptophan isomers and incorporation of that label into free indole-3-acetic acid (IAA). Both lines required levels of L-[N-15]tryptophan 2 to 3 orders of magnitude over endogenous levels in order to obtain measurable incorporation of label into IAA. Labeled L-tryptophan was extractable from plant tissue after feeding and showed no measurable isomerization into D-tryptophan. D-[N-15]tryptophan supplied to Lemna at rates of approximately 400 times excess of endogenous D-tryptophan levels (to yield an isotopic enrichment equal to that which allowed detection of the incorporation of L-tryptophan into IAA), did not result in measurable incorporation of label into free IAA. These results demonstrate that L-tryptophan is a more direct precursor to IAA than the D isomer and suggest (a) that the availability of tryptophan in vivo is not a limiting factor in the biosynthesis of IAA, thus implying that other regulatory mechanisms are in operation and (b) that L-tryptophan also may not be a primary precursor to IAA in plants.

Membrane fractions enriched in endoplasmic reticulum, tonoplast, and plasma membrane were isolated using sucrose gradients and the membrane polypeptides separated using sodium dodecyl sulfate polyacrylamide gel electrophoresis. When the membrane fractions were incubated with gamma-[P-32]ATP, phosphorylation occurred almost exclusively in the plasma membrane fraction. Phosphorylation of a band at 38 kilodaltons increased as the concentration of Mg2+ was decreased from millimolar to micromolar levels. Phosphorylation of bands at 125, 86, 58, 46, and 28 kilodaltons required millimolar Mg2+ concentrations and was greatly enhanced by Ca2+. When roots of intact plants were labeled with [P-32]orthophosphate, polypeptides at approximately 135, 116, 90, 46 to 53, 32, 28, and 19 kilodaltons were labeled in the plasma membrane fraction and polypeptides at approximately 73, 66, and 48 kilodaltons were labeled in the tonoplast fraction. Treatment of the roots of intact plants with 150 millimolar NaCl resulted in increased phosphorylation of some polypeptides while treatment with 100 mM NaCl had no effect.

The humoral immune response was measured prior to 24 days of age, depending on the vaccine. Chicks were divided into two populations according to their antibody response: a population of high responders to both antigens and a population of low responders. After four generations of selection, a significant difference was observed in the immune response of the two populations, and, therefore, an attempt was made to identify possible differences in the segregation of major histocompatibility complex genes. Using alloantisera prepared in B-congenic White Leghorn, the high responders exhibited a high percentage of chickens having erythrocytes agglutinated with B5 antisera, and the low responders exhibited a high percentage of chicks with erythrocytes agglutinated with B15 and B19 antisera. The B13 antisera agglutinated cells of similar proportions of chickens in the two populations. A random commercial broiler flock was screened with the antisera, and correlation was high between B haplotype and antibody level to E. coli following vaccination. The present work indicated the possibility of a direct association between the genetic characteristics represented in the B complex and humoral antibody response in a broiler population.

Male broiler chicks, 100 per trial, were raised as one group to 29 days for Trial 1 and 36 days for Trial 2. The birds were moved to environmental chambers and 50 per trial were acclimated by being subjected to 3 consecutive days of 24 C, 35 C, 24 C cyclic temperature. After acclimation, the birds were exposed to a linear change in temperature from 24 to 41 C over 3 h with a constant 10 C dewpoint, starting at 0800 h on Day 34 for Trial 1 and on Day 41 for Trial 2. The feeding schedule for the day of the heat exposure was as follows. For the feed group, feed was removed from the birds at 0400 h and placed back at 0700 h. For the no feed group, feed was removed at 0700 h. At 0800 h, feed was removed from all birds but water was accessible throughout the heat exposure. Acclimated and unacclimated birds given access to feed for 1 h before a heat exposure consumed 60 and 50 mL of water per broiler, respectively, during the heat exposure. However, for broilers not receiving feed, the water consumption was 58 and 30 mL per broiler, respectively. Acclimated and unacclimated broilers given access to feed had similar body temperatures, but the acclimated broilers not receiving feed had a significantly lower ending rectal temperature than the unacclimated group.

When measured at 6 days postinoculation, the acute stage of the infection, the epinephrine and norepinephrine levels of the infected poults showed a dose-dependent increase over levels in controls, with poults that were most heavily infected having the highest levels. The catecholamines appeared to show a classic stress-elicited response: this response increases with time to high levels during the acute stage of the infection, and then returns to levels approximately the same as those of the controls as the poults recover from the infection. Anorexia, or feed restriction, appeared to be primarily responsible for the increase in norepinephrine. However, epinephrine levels in the infected poults were significantly higher than in their pair-fed, uninfected counterparts, indicating that factors other than reduced feed consumption contributed to the increase. The data indicate that plasma catecholamines are increased during coccidial infection. As pressor compounds, they may contribute to the previously observed changes in blood pressure and heart function in infected poults.

Median colonization dose (CD50), a measure indicating the number of organisms required to colonize one-half of the challenged chickens, was used to assess the influence of these organisms upon the colonization of one another. Chicks were gavaged with serial dilutions of 1) C. jejuni, 2) S. typhimurium, 3) dilutions of C. jejuni and a fixed level of S. typhimurium, or 4) dilutions of S. typhimurium and a fixed level of C. jejuni. Six days postchallenge, cecal contents were quantitatively assayed for the challenge organisms. Birds challenged with only C. jejuni or birds challenged with both C. jejuni and S. typhimurium had a CD50 of 120 C. jejuni cells. The CD50 values for S. typhimurium alone (48 cells) and S. typhimurium simultaneously colonized with C. jejuni (180 cells) were not significantly different (P < .05). The colonization levels of either organism were generally correlated with the challenge dose and ranged up to 63 million cells per gram. It was concluded that the CD50 for both C. jejuni and S. typhimurium in 24-h-old chicks were similar, and the presence of one of these particular co-colonizers does not influence the CD50 of the other.

Experiments were conducted to assess the optimal time to perform surgical in ovo bursectomy in turkey embryos for the lowest mortality rate. Factors such as the ease of operation, hatchability, and least deaths were considered. Surgical bursectomies at 25, 24, 23, and 22 day embryonation resulted in 75, 20, 0, and 10% hatchability, respectively. The surgical procedure performed at 25-day embryonation resulted in superior hatchability and ease of operation, and it was less traumatic as evidenced by fewer deaths. The hatchability of embryos injected with testosterone (TE) at 15 days incubation was 55%. Birds subjected to surgery or chemical treatment had increased mortality rates. Cyclophosphamide (CY) treatment at 1 and 2 days posthatch caused a significant increase in deaths over groups not treated with CY. Both primary and secondary KLH responses were significantly lower in bursectomized and TE-injected groups, than in shamoperated or nonoperated control groups.

A total of 144 commercially reared female broilers was obtained from the holding area of a local processor, and housed for 5 days in floor pens to recover from the stress associated with transport to the plant. After 5 days, the birds were placed in one of two finishing batteries for 48 h prior to feed withdrawal treatments. Feed withdrawal times were 0, 8, 16, or 24 h prior to slaughter. Measurements included live shrink, prechill and postchill carcass yields, breast meat yield, pH at 2 and 4 h PM, and shear values. There was a progressive loss in body weight as feed withdrawal time increased. The 0-h withdrawal treatment resulted in the lowest prechill yield. Quadratic effect of feed withdrawal on shear values was significant. Breast meat from the 0-h withdrawal treatment required more force to shear, 7.09 kg, than did the meat from the 8 and 16 h treatments, 5.84 and 5.78 kg, respectively; meat from the 24-h treatment required 6.01 kg. The results indicate that feed withdrawal schedules can affect not only the carcass yields but also the objective texture of broiler meat deboned 4 h PM.

A streptomycin-resistant mutant was used in these studies to allow accurate estimations of the surviving salmonellae in the presence of residual normal flora. This strain has been demonstrated to have no significant shift in its biological properties nor in its resistance to ionizing radiation. The response of S. typhimurium to gamma radiation was similar on both chicken legs and MDCM. The radiation was significantly more lethal to the bacterial cells at temperatures above freezing. The response-surface equations developed from the studies predict that the number of viable cells per gram of MDCM or per square centimeter of the surface of chicken legs would be reduced approximately 2.8 to 5.1 log units at 0 C by radiation doses within the range of 1.5 to 3.0 kGy. The results of the present studies are similar to those obtained previously with sterile mechanically deboned chicken meat.

Nymphs emerged from burrows in the ground from late April through early May, crawled up trees and other accessible objects and molted in one to several hours. Adults soon attracted attention, the males with their courting songs and both sexes with erratic flight. Females made punctures in twigs, deposited an average of 16 firm, white eggs in pockets (egg nests) in the punctures and died by 1 July. Eggs hatched in four to six weeks or collapsed, and nymphs fell to the ground to burrow in it or died in the nests. Hatched eggs did not change color or appear perceptibly different from July 1987 to November 1990; collapsed eggs and dead nymphs became brown. Between August and November 1987 many twigs broke at punctures and dropped to the ground; many others remained on the trees, continued to grow and partially or completely enclosed punctures by November 1990.

These two forms of lactoferrin, demonstrated to be entirely of maternal origin, were copurified using affinity columns of immobilized single-stranded DNA-agarose. The relative concentrations of the intact lactoferrin and the "nicked" lactoferrin were determined after denaturation and separation by reverse-phase HPLC. N-terminal sequence analyses showed that the intact 78-kDa form had lost two residues from its N terminus. The nicked 78-kDa form was composed of only two fragments; one fragment was identified as the N terminus of the N-lobe (residues 3-283). The other fragment started with Ser-284 and included the alpha-helical structures at the C terminus of the N-lobe, as well as the entire C-lobe. Although no disulfide bonds connect these two fragments, they were tightly associated in vivo and were not separated in vitro except under denaturing conditions. Limited in vitro digestion of human milk lactoferrin with trypsin produced a nicked, but stable (78-kDa), form of DNA-binding lactoferrin nearly indistinguishable from the isolated urinary lactoferrin, except for the absence of one additional arginine residue at the N terminus of the N-lobe. Residues involved in the stable molecular interaction between fragments were evaluated using data obtained from the high-resolution crystal structure of hololactoferrin. Two features, entirely within the N-lobe, account for the lack of fragment dissociation after cleavage at residue 283 in vivo: an extensive interface at the hinge region behind the iron-binding cleft and an "anchor" sequence traversing the remainder of the N-lobe at 90-degrees relative to the fragment interface. These results document the remarkably limited degradation of absorbed lactoferrin in vivo and suggest that iron-binding activity, receptor-binding properties, and postulated immune cell regulatory functions remain intact.

Five forest types were represented: Abies balsamea (L.) Mill., Pinus banksiana Lamb., Pinus resinosa Ait., Populus tremuloides Michx., and northern hardwoods dominated by Acer saccharum Marsh. Samples were analyzed for pH, total N and S, loss on ignition, and exchangeable Ca, Mg, K, Na, and acidity; the latter were summed to yield cation exchange capacity. Data for each variable included 40 pairs of laboratory duplicates; 45 samples representing three sampling points approximately 2.5 m apart within a subplot in each of 15 plots (spatial scale of 10(0.4) m between samples); and 830 samples from five subplots approximately 30 m apart within the 171 plots (scale of 10(1.5) m). Variation among samples was determined for each of those categories, as well as among the nearly 35 plots within a forest type at approximately 100 km apart (scale of 10(5) m), and among the five forest types. Increase in variation with spatial scale was statistically significant. Coefficients of variation were very similar to those from other studies; considering the range of locations, soils, and vegetation in the literature, reported coefficients of variation for soil properties are remarkably uniform. None of the variables was normally distributed, even after log or algebraic transformations. Determination of number of samples necessary to characterize a system adequately is fraught with uncertainty regarding assumptions of the form of the distributions and of the level of precision desired. The commonly accepted precision of 10% of the mean from a normal distribution at a defined confidence level needs re-evaluation. C1 US FOREST SERV,N CENT FOREST EXPT STN,ST PAUL,MN.

Three starch/water ratios, 35/65, 50/50, and 65/35, were evaluated for efficiency to encapsulate 13.9% EPTC on a dry starch basis. Analysis of extrudates, after drying and grinding to the desired particle size, showed recovery of active ingredient (a.i.) and effectiveness of encapsulation to be best at 35% starch solids (35/65 starch/water ratio). Scanning electron micrographs showed smaller and a more even distribution of a.i. at 35% starch. Suspending particles in water caused a release of EPTC which increased with agitation and smaller mesh size. Air-dried particles released EPTC more slowly than over-dried particles of the same mesh range. Particles from extrusion at 35% solids released a.i. more slowly than those from extrusion at 65% solids. The slowest releasing particles showed the least swellibility. EPTC was also encapsulated at 10.2% a.i. using 20% and 35% starch solids with steam-injection cooking followed by Sigma blade mixing for comparison with an extrusion. Herbicide retention and encapsulation were superior, release of a.i. into water was slower, and swelling of particles was less in twin-screw extrusion prepared products.

However, municipal wastepaper recycling is not primarily an industry problem. Because of the abundance of North American forest resources, the pulp and paper industry has not been compelled to solve the complex problems associated with recycling its products. The paper industry does well at recycling old newspapers and old corrugated containers, but mixed office wastes and paper and plastic wastes from fast-food services pose serious technical problems. The responsibility for finding new ways to encourage industry to recycle more of these hard-to-recycle wastes falls to government at all levels. Although there are legislative or regulatory actions that do encourage recycling, but a far more economical and satisfactory approach would be a cooperative government-industry effort to overcome technical barriers to increased recycling. The Forest Products Laboratory is sponsoring research addressing major technical problems. More needs to be done to increase the nation's recycle rate for paper and wood products in the municipal solid waste stream.

Cotton arrays are taken before and after each processing operation, and the change in length distribution indicates fiber damage during processing. However, the Fibroliner used in the system also loses or breaks fibers. To measure the differences in fiber length distribution caused by the Fibroliner, three varieties of cotton were sent to USDA, AMS, Clemson, where they were sorted into known length groups using the Suter-Webb method. These three sorted varieties of known length distributions were re-sorted with the Fibroliner and analyzed with the Almeter. The results show a discrepancy in the short fiber content and the presence of fibers that were not in the original array.

Our objective was to find a suitable laboratory animal model for measuring larkspur toxicity for subsequent use as an estimator of toxicity to cattle. The LD50 for subcutaneous injection and for oral gavage of extract from Delphinium barbeyi, a highly toxic and troublesome rangeland tall larkspur, was compared for mice, hamsters, rats and sheep. Similarity of primary clinical signs of poisoning and lack of significant difference in slope of the dose-response curves implied that the overall effect of the larkspur alkaloids was the same for all rodent species tested. Sheep were the most susceptible to poisoning by subcutaneous injection of larkspur extract with decreasing susceptibility in hamsters, mice and rats, but sheep had least susceptibility when comparing response to oral (by gavage) doses. Also, death occurred rapidly after gavage as compared with subcutaneous doses in mice, hamsters and rats, but was nearly the same for sheep. We conclude that, of the animals tested, mice would be the best choice for a bioassay of the toxicity of larkspur because of their high susceptibility, rapid response time, and small dose requirement.

The purpose of the analysis was to determine if any unexpected disturbances had influenced the growth of the trees. Current September temperature, August rainfall and February Palmer Drought Severity Index (PDSI) were found jointly to be the best variables in the model to predict growth. August rain had a constant significant effect on growth and February PDSI was not significant except between the years 1968-1983. It was concluded that the Harrison area has been in equilibrium for the past 50 years since no apparent outside influences have caused the trees to become less sensitive to climate. Thus, the forest is a good candidate for a Research Natural Area. RP DEVALL, MS (reprint author), US FOREST SERV,SO FOREST EXPT STN,701 LOYOLA AVE,ROOM T-10210,NEW ORLEANS,LA 70113, USA.

The simulation modeling approach followed in this analysis consists of a mathematical programming model and leaching/surface runoff, Pesticide Root Zone Model (PRZM) models. Special care was taken to ensure that the physical model was sensitive to the chemical characteristics of individual pesticides and the important physical changes brought about by different agricultural practices. Results show that, although these programs as now planned, increase farm income and achieve soil conservation goals, they may adversely affect ground water quality. Also, depending on soil and location characteristics, there are tradeoffs between surface and ground water quality implications. Hence, if these programs are to address water quality problems, the recommended practices must be evaluated for their impact on water quality, particularly in potentially vulnerable areas.

Hydrologic records were analyzed for the period 1953 and 1988 from Watershed (WS) 1 (clearcut logged and burned), WS 2 (unlogged control), and WS 3 (25 percent patch-cut logged and burned) in the H. J. Andrews Experimental Forest, western Cascade Range, Oregon. These records spanned 9-10 years before logging, and 21-25 years after logging and burning. Streamflows in August were the lowest of any month, and were unaffected by occasional heavy rain that occurred at the beginning of summer. August streamflows increased in WS 1 compared to WS 2 by 159 percent following logging in WS 1, but this increase lasted for only eight years following the start of logging in 1962. Water yield in August for 1970-1988 observed from WS 1 was 25 percent less than predicted from the control (WS 2, ANOVA, p = 0.032). Water yield in August increased by 59 percent after 25 percent of the area of WS 3 was patch-cut logged and burned in 1963. In contrast to WS 1, however, water yields from WS 3 in August were consistently greater than predicted for 16 years following the start of logging, through to 1978. For the 10 years, 1979-1988, water yield observed in August from WS 3 was not different than predicted from the control (WS 2, ANOVA, p-0.175). The contrasting responses of WS 1 and 3 to logging are thought to be the result of differences in riparian vegetation caused by different geomorphic conditions. A relatively wide valley floor in WS 1 allowed the development of hardwoods in the riparian zone following logging, but the narrow valley of WS 3 and limited sediment deposits prevented establishment of riparian hardwoods. Low streamflows during summer have implications for salmonid survival. Reduced streamflow reduces the amount of rearing habitat, thus increasing competition. Combined with high water temperatures, reduced streamflow can lead directly to salmonid mortality by driving salmonids from riffles and glides, and trapping them in drying pools. Low streamflow also increases oxygen depletion caused by leaves from riparian red alders. C1 OREGON STATE UNIV,DEPT FOREST ENGN,CORVALLIS,OR 97331.

Ammonium nitrate and triple superphosphate were applied simultaneously at rates of 336 kg ha-1 N and 224 kg ha-1 P2O5, respectively, which are similar to rates used in commercial forest operations. The treatment significantly increased outputs of several ions. Annual outputs of nitrate N increased as much as 18 times over pretreatment levels, and calcium and magnesium increased as much as three times over pretreatment levels the first year after fertilization. Outputs for these nutrients were elevated for all three post-treatment years. Although nitrate N increased significantly, only about 20 percent of the applied fertilizer was accounted for in stream water exports. Outputs of phosphate P declined following fertilization, probably because the watersheds are phosphorus deficient, but by the third year, they slightly exceeded predicted values. Estimated nutrient losses to deep seepage were substantial, especially on the leakier south-facing catchment, on which some nutrient losses were equal to or greater than those in stream water. When the nutrient exports associated with both stream discharge and ground water recharge were combined, the percentages of applied N that were lost were similar on the two watersheds, averaging 27.5 percent. Less than 1 percent of the applied P was lost from either watershed in the combination of streamflow and deep seepage. C1 US FOREST SERV,NE FOREST EXPT STN,HEADQUARTERS OFF,RADNOR,PA 19087.

After a 23-year calibration with an undisturbed control catchment, mixed stands of shortleaf pine (Pinus echinata Mill.) and hardwoods were clearfelled on two small catchments in the hilly Coastal Plain of north Mississippi and observed for five years. Runoff increased 370 mm (skidded) and 116 mm (yarded) during the first year with 1876 mm of rainfall, and 234 mm (skidded) and 228 mm (yarded) during the second year when 1388 mm of precipitation equaled the calibration mean. Sediment concentrations for the yarded catchment during the first two years averaged 641 and 1,629 mg L-1, respectively, and yields were 6,502 and 12,086 kg ha-1. Compared to calibration means of 74 mg L-1 and 142 kg ha-1, these extreme values can be attributed largely to transport of sediment stored in the channel and to erosion of subsurface flow paths, which was exacerbated by high flow volumes. During the first year, the concentration (231 mg L-1) and yield (2,827 kg ha-1) for the control catchment also exceeded the calibration means. However, concentrations (134 mg L-1) and yields (1,806 kg ha-1) for the skidded catchment were about 40 percent lower than for the control catchment during the first year, and were higher than those for the control only during the second year. Because deep percolation was limited and because rainfall was unusually high, increases in flows and sediment concentrations and yields probably approximate maximum responses to clearcut harvesting in the uplands of the southern Coastal Plain.

Currently, most in situ methods for estimating the unsaturated hydraulic conductivity (K) are based on analyses that require estimates of the soil water flux and the pressure head gradient. These analyses typically involve differencing of field-measured pressure head (h) and volumetric water content (theta) data, a process that can significantly amplify instrumental and measurement errors. More reliable methods result when differencing of field data can be avoided. One such method is based on estimates of the gravity drainage curve K'(theta) = dK/d-theta which may be computed from observations of theta and/or h during the drainage phase of infiltration drainage experiments assuming unit gradient hydraulic conditions. The purpose of this study was to compare estimates of the unsaturated soil hydraulic functions on the basis of different combinations of field data theta, h, K, and K'. Five different data sets were used for the analysis: (1) theta-h, (2) K-theta, (3) K'-theta; (4) K-theta-h, and (5) K'-theta-h. The analysis was applied to previously published data for the Norfolk, Troup, and Bethany soils. The K-theta-h and K'-theta-h data sets consistently produced nearly identical estimates of the hydraulic functions. The k-theta and K'-theta data also resulted in similar curves, although results in this case were less consistent than those produced by the K-theta-h and K'-theta-h data sets. We conclude from this study that differencing of field data can be avoided and hence that there is no need to calculate soil water fluxes and pressure head gradients from inherently noisy field-measured theta and h data. The gravity drainage analysis also provides results over a much broader range of hydraulic conductivity values than is possible with the more standard instantaneous profile analysis, especially when augmented with independently measured soil water retention data.

Barnyardgrass reduced grain yield of Lemont, a semidwarf cultivar, more than Newbonnet, a short-statured cultivar. Linear regression indicated that season-long interference of barnyardgrass at 1 to 20 plants m-2 reduced grain yields of Lemont and Newbonnet by 301 and 257 kg ha-1 per barnyardgrass plant, respectively. Grain yields of Lemont and Newbonnet were reduced by barnyardgrass densities to 40 plants m-2 but were not affected further at densities greater-than-or-equal-to 40 plants m-2. Barnyardgrass reduced straw yield of Lemont more than of Newbonnet. Although barnyard-grass culms m-2 and straw yield increased as weed density increased, the weed produced more culms per plant at 2 and 5 m-2 than at 20 to 80 m-2. In a spatial interference experiment, Lemont grain yield reduction averaged 21 % when plants were grown within 0 to 25 cm of a barnyardgrass plant groups (group = 4 plants per 140 cm2). However, rice yields were not reduced when barnyardgrass plant groups were 25 to 50 to 100 cm away. Additional treatments included two barnyardgrass groups spaced 20, 40, 80, or 100 cm apart. When Lemont grew between barnyardgrass groups spaced 20 or 40 cm apart, grain yields were reduced 40 and 27%, respectively, compared with weed-free rice. However, Lemont yield was not reduced when rice plants grew between weed plant groups spaced 100 cm apart. C1 USDA,ARS,STUTTGART,AR 72160. UNIV ARKANSAS,ALTHEIMER LAB,DEP AGRON,FAYETTEVILLE,AR 72703.

This interference reduced straw dry weights of Newbonnet and Lemont by 100 and 130 kg ha-1 per red rice plant, and grain yields by 178 and 272 kg ha-1 per red rice plant, respectively. Grain yield reductions were due to decreases in panicle number and length, and in number of grains per panicle. Ten plants m-2 or more reduced height of Lemont, while 40 plants m-2 were required to reduce height of Newbonnet. Red rice at 10 plants m-2 or more reduced total milled and head rice yields of Lemont, but red rice did not affect these components for Newbonnet. Red rice interfered with rice, even at densities as low as two plants m-2, and interference was greater in Lemont, a semidwarf cultivar with mature plants 92 cm tall, than in Newbonnet, a conventional cultivar with mature plants 115 cm tall. Red rice produced more panicles m-2 and 31 to 64% greater straw dry weight when grown with Lemont than when grown with Newbonnet because red rice shaded Lemont more than Newbonnet. Red rice plants grew taller as red rice densities increased and also were taller when grown in Newbonnet than when grown in Lemont. C1 USDA,ARS,STUTTGART,AR 72160.

Within the no-tillage treatment, rye or hairy vetch residue reduced total weed density an average of 78% compared to the treatment without cover crop when cover crop biomass exceeded 300 g m-2 and when residue covered more than 90% of the soil. Goosegrass, stinkgrass, and carpetweed densities were reduced by cover crop residue in at least 1 yr whereas large crabgrass was unaffected.

Mean emergence depths in no-till were the shallowest, followed by chisel plow and conventional tillage at each location. At least 40% of the giant and green foxtail plants emerged from the upper 1 cm of soil in no-till compared to about 25% in chisel plow and less than 15% in conventional tillage. As many as 25% of the plants emerged from greater than 4 cm in conventional tillage compared to about 10% in chisel plow and less than 5% in no-till. Seedlings emerged from greater depths in a loamy sand than in a silt loam soil regardless of tillage system. At Arlington, green foxtail was the dominant species in conventional tillage, while giant foxtail dominated in chisel plow and no-till. Foxtail densities were greater in chisel plow and no-till than in conventional tillage at all three locations. C1 LANDIS INT INC,RES,VALDOSTA,GA 31601.

Giant foxtail did not germinate at 5 C and failed to emerge from 6 cm deep within 21 days at 10 C. Increasing soil temperature above 10 C increased giant foxtail germination and emergence. Velvetleaf germinated at 5 C but did not emerge within 21 days. Velvetleaf emerged within 21 days from soil depths of 2 to 6 cm at soil temperatures of 10, 15, and 20 C. Giant foxtail and velvetleaf seed germinated on a soil surface kept moist by mulch or frequent watering. Giant foxtail seedling survival was 100% after germination on the soil surface. Velvetleaf often failed to become established; only 28% of the velvetleaf that germinated at 20 C survived. Injury to giant foxtail by cyanazine increased with increasing soil temperatures and decreasing seed depths. Cyanazine placement above or below the seed did not have a consistent effect on giant foxtail injury. Cyanazine placed above the seed was more injurious to velvetleaf than placement below at 15 and 20 C. Differential responses of giant foxtail and velvetleaf seed germination and seedling survivability to initial seed depth appears to be a major factor in weed population shifts when tillage is reduced or eliminated.

The ability of seed to germinate was studied by incubating spikelets under constant, defined incubation conditions after retrieving samples from the field every 2 weeks over 2 yr. Less than 8% of jointed goatgrass seed that were initially set outdoors survived beyond 2 yr when left undisturbed on the soil surface or buried 5 cm deep. Periods of greatest seed loss coincided with periods of peak emergence in fall (late September and October). The ability of seed to germinate also peaked in fall and preceded the period of greatest field emergence and greatest decreases in seed survival.

At equivalent total quantities applied, absorption by leaves was greater with concentrated droplets than with more dilute droplets in greater number. Increasing the surfactant concentration increased the relative absorption of dilute glyphosate droplets but did not overcome the negative effect of higher droplet number on total amount absorbed. More glyphosate was translocated from concentrated versus the most dilute droplets at equivalent total quantity applied. Conversely, more absorbed glyphosate from dilute droplet applications remained in the treated leaves. About 90% of translocated C-14 glyphosate from the most concentrated drops was distributed evenly between roots and shoot tissue above the treated leaf and the remainder in shoot tissue below the treated leaf. As droplet number increased and surfactant concentration decreased, the relative amount of glyphosate distributed in roots declined in relation to shoots. C1 CORNELL UNIV,USDA ARS,ITHACA,NY 14853.

Alfalfa was grown in soil columns for 6 months and then killed with glyphosate. The C-14-atrazine and C-14-alachlor were applied to soil columns with bromide following 2, 13, or 26 weeks of root decomposition. Most of the herbicide remained in the top 9 cm of soil. However, atrazine and alachlor soil distribution profiles indicated greater preferential movement in columns with roots than in columns without roots. Higher levels of atrazine and alachlor were bound to soil at lower depths in the presence of roots than without roots. Adsorption of atrazine and alachlor on soil with and without alfalfa roots was not significantly different as determined by Freundlich adsorption isotherms. Degradation rates for atrazine and alachlor were not substantially different between soil with and without roots. Although only small amounts of the applied herbicide leached through the columns, preferential flow of herbicides through root-mediated soil macropores and cracks could be a mechanism of herbicide transport through soil under appropriate conditions.

When 2,4-D symptoms in July were severe, yields were reduced by as much as 85%. However, when 2,4-D symptoms in July were slight (less than 2 on a 0 to 6 visual scale), grape yields were not reduced. A second-order polynomial described well (R2 = 0.92) the relationship between symptoms and grape yield. Symptoms of 2,4-D on grape leaves did not persist beyond the year of treatment, although grape yields did not recover fully until the second year after the last 2,4-D treatment. In the first year of 2,4-D treatments, low grape yields were correlated with reduced weight and number of berries per cluster. In the second and third year of treatment, low grape yields were correlated with fewer clusters per shoot in addition to lower cluster weight and fewer berries per cluster. When 2,4-D was applied one year only, soluble solids in the grape juice were reduced as much as 9%, although reductions were not related to severity of foliar symptoms. When 2,4-D was applied for three consecutive years, soluble solids in the juice were consistently higher in grapes with moderate to severe 2,4-D symptoms. There were no consistent effects of 2,4-D on juice color or titratable acidity. The pH of fresh juice was increased slightly by 2,4-D with the maximum being 10% after 3 yr of consecutive treatments. In the first subsequent nontreatment year after 3 yr of 2,4-D treatments, juice quality was similar to the quality of nontreated grapes. At a detection limit of 0.05 ppmw, 2,4-D was not detected in the harvested grapes. Based on the results of these experiments, grapes with slight 2,4-D symptoms would not be expected to have reduced yields or reduced juice quality.

Test plot data for the years 1981 through 1988 from the Purdue University Agronomy Farm, which has highly productive, well-drained soils, were analyzed. Net incomes for no-till tillage systems on all farms in the model were consistently and significantly lower than incomes for moldboard and chisel plow tillage systems due to slightly lower yields and substantially higher herbicide costs. Generally, net farm incomes were slightly higher with a moldboard plow versus chisel plow tillage system. Also, as farm size increased, per hectare net incomes increased. About 80% of the time under moldboard or chisel plow tillage systems, the model chose as optimal the lowest of three herbicide application rates. A corn/soybean rotation was chosen as optimal on 56% of the farm area analyzed, versus 25% for continuous corn and 13% for a corn/soybean/wheat rotation.

At the end of the growing season, yellow nutsedge shoot dry weight per m2 in plots where the two species were planted together was less than 10% of shoot weight in plots where nutsedge was grown alone. Presence of yellow nutsedge did not markedly affect sweet potato growth. When grown together in a greenhouse experiment designed to minimize the competitive effects of sweet potato on yellow nutsedge, yellow nutsedge growth was reduced more than 50% by sweet potato 8 and 12 weeks after planting. The most polar fraction of serially extracted sweet potato periderm tissue was highly inhibitory to yellow nutsedge root growth. These results indicate that sweet potato interference with yellow nutsedge under field conditions is partially due to allelopathy. RP HARRISON, HF (reprint author), USDA,ARS,CHARLESTON,SC 29414, USA.

Based on injury ratings, Capsicum annuum, C. chinese, and C. frutescens accessions were mostly intermediate in response to bentazon with relatively few highly tolerant or susceptible. Most of C. bacatum, C. chacoense, and C. pubescens and the unspeciated accessions were susceptible. Greenhouse experiments indicated that although most of the tolerant selections were highly tolerant, none was more tolerant than the C. annuum cultivars 'Santaka' or 'Bohemian Chili'. None of the susceptible selections were more susceptible to bentazon than the C. annuum cultivar 'Sweet Banana'. Individual plants that were highly tolerant were self-pollinated to produce progeny that were all highly bentazon tolerant, but none was more tolerant than Santaka or Bohemian Chili.

Trend analyses of johnsongrass recovery, based on panicle numbers late in the growing season, indicated a quadratic response with panicle numbers being lowest when asulam at 2.8 kg ai ha-1 was applied in a diluent volume approaching 187 L ha-1. The response was similar regardless of whether droplet size or number was altered to obtain these diluent volumes. Differences in late-season johnsongrass control were reflected in harvested sugarcane stalk populations and net cane yields. In greenhouse studies, johnsongrass plants were thoroughly washed with water 24 h after treatment with asulam at 2.8 kg ha-1 at water volumes ranging from 47 to 374 L ha-1. Asulam absorption, as evidenced by reduction in the growth of johnsongrass, was higher when surfactant was included, but was not affected by diluent volumes in the range evaluated.

Alternaria cassiae, a pathogen of sicklepod, proliferated after incorporation of spores in the emulsion. The oil phase (CDQ-1) contained paraffin wax, a paraffinic spray oil, and an unsaturated monoglyceride emulsifier (Myverol 18-99). The oil phase was mixed 1:1 (by weight) with water to form the invert, which was sprayed onto glass plates for testing of water retention properties. Water contents ranged from 22% (with A. cassiae present) to 41% (without fungus) for 0.6 to 0.7-mm2 spray deposits after 24-h storage at 21 C and 65% relative humidity.

Strength is not a critical factor. The objective of this study was to determine if a gap in a glueline can be detected by mechanical means. Furniture manufacturers want to be sure that any blank that they buy will have continuous gluelines. Every blank should be nondestructively tested, and all blanks with a defective glueline should be rejected from the shipment. Black cherry, red oak, and yellow-poplar standard-size blanks 24 inches wide and 0.75 inches thick were manufactured. Some blanks were crosscut into strips two inches along the grain. The other blanks were cut 24 inches long. Foil defect strips were placed in the middle glueline of some panels to create a gap, thus achieving a range of effective gluelines of 60, 75, 90, and 100%. Static bending perpendicular to the grain, tension perpendicular to the grain, and torsion tests were developed for testing these specimens. Five parameters-modulus of rupture and modulus of elasticity in bending, tensile strength, torsional shear strength, and modulus of rigidity-were measured to determine their sensitivity for detecting defective gluelines. Based on the results of this study, tensile strength perpendicular to the grain is the most satisfactory parameter for detecting defective gluelines. Its combination of high sensitivity and low variability would result in the smallest amount of destruction of good panels, while failing a larger number of defective panels. It was found that mechanical methods are not appropriate for determining glueline continuity since none of the parameters studied is sufficiently sensitive to detect defects of 10% or less.

Acetylated fiberboards swelled less than untreated fiberboards after weathering. Acetylated fiberboards were smoother than untreated ones after treatment, and acetylation helped retain surface smoothness of both finished and unfinished fiberboards after weathering. Finished and unfinished acetylated fiberboards also had less mildew growth after outdoor weathering compared to untreated fiberboards, demonstrating the greater biological resistance of the treated boards. A penetrating semitransparent oil-based stain did not perform as well on acetylated fiberboard as on untreated fiberboard because the finish could not penetrate the treated surface. Therefore, not as much material could be applied to the acetylated boards. Film-forming finishes (paints and solid-color stains) performed equally well on acetylated and untreated boards after 2 years of outdoor exposure.

The prediction model approximated vaporization from the crystal fragments most exposed on a snow surface by sublimation of uniform ice spheres. Monitoring temperature, humidity, radiation and wind speed over four winter months in a cold, dry climate provided data to estimate sublimation rate, dm/dt, for a 1-mm diameter ice sphere during each 15-min period. Weighing interception on the 1-m high, artificial tree provided measures of sublimation rate, dM/dt. Periods with and without snowfall were analyzed separately. Proportionality factor, Z, in the hypothesis, dM/dt = Z(dm/dt), was a function of intercepted mass, M, that depended on the time since snowfall ceased. Parameter a in the equation Z = aM(b), decreased by a factor of 2 as time after snowfall increased to 8 h. This result could reflect an increase in size, and decrease in the number, of vapor sources on each unit area of snow surface exposed. Parameter b, describing the change in exposed area with mass, first increased then decreased as increasing interception bridged between branches. The experiment determined b = (0.7 - 5 x 10(-5) M) for the artificial tree. RP SCHMIDT, RA (reprint author), ROCKY MTN FOREST & RANGE EXPT STN,240 W PROSPECT ST,FT COLLINS,CO 80526, USA.

The atmospheric concentrations of both gases have increased dramatically over the past few decades, and continue to increase at a rate of approximately 1.1 and 0.25% yr-1 for CH4 (ref. 2) and N2O (ref. 3) respectively. Increased biospheric production is generally suggested as the reason for the increases, but decreases in global sinks may also be important. It has been suggested, for example, that nitrogen fertilization may decrease the rate at which tropical 4,5 and temperate forest soils 6 take up methane from the atmosphere. Furthermore, the recent extensive changes in land management and cultivation could be contributing to the observed increases in both atmospheric CH4 and N2O, as has been suggested for tropical soils 7. Little information exists on CH4 uptake in temperate grasslands (which currently occupy approximately 8% of the Earth's surface), its relation to N2O production, or the effect of land management or cultivation 8,9. Here we report measurements of CH4 uptake and N2O emissions in native, nitrogen-fertilized and wheat-growing prairie soils from spring to late autumn, 1990. We found that nitrogen fertilization and cultivation can both decrease CH4 uptake and increase N2O production, thereby contributing to the increasing atmospheric concentrations of these gases.

Foci of cells along the lateral veins do not differentiate properly, but continue to divide, forming outpocketings or knots. The ligule, a fringe normally found at the junction of leaf blade and sheath, is often displaced and perpendicular to its normal position 1-3. The phenotype is manifested in all cell layers of the leaf blade, but is controlled by a subgroup of cells of the inner layer 4. Mutations result from the insertion of transposable elements 5 or a tandem duplication 6. We show that the Kn1 gene encodes a homeodomain-containing protein, the first identified in the plant kingdom. Sequence comparisons strongly suggest that Kn1 acts as a transcription factor. Here we use the Kn1 homeobox to isolate other expressed homeobox genes in maize. The Kn1 homeobox may permit the isolation of genes that, like animal and fungal counterparts 7, regulate cell fate determination. C1 USDA ARS,CTR PLANT GENE EXPRESS,800 BUCHANAN ST,ALBANY,CA 94710.

These studies, along with X-ray diffraction and solid-state NMR data, show that amylose and EAA, as well as amylopectin and EAA, form helical V-type inclusion complexes when mixed in aqueous suspension. This structure apparently accounts for the partial compatibility observed in films containing starch and EAA. About 2/3 by weight of EAA does not interact with amylose and probably represents the ethylene-rich central core of the EAA micelle. EAA/amylose complexes in 10 mM NaOH were stable to temperatures > 90-degrees-C, whereas EAA/amylopectin complexes in the same solvent were largely disrupted at this temperature. Urea, at a concentration of 8 M, further destabilized both EAA/amylopectin and EAA/amylose complexes. Solutions with an alkaline pH (> 9.5) dispersed EAA optimally and allowed maximum complexing with amylose. At pH values > 13, the EAA/amylose complexes were weaker, most likely due to electrostatic repulsion between ionized hydroxyl groups of amylose and carboxyl groups of EAA.

A Plackett-Burman fractional factorial experimental design was employed with 10 total variables. Eight media components, plus two levels of inoculum, were tested in all systems. Other variables were light vs. dark for MF, agitation level for LF, vermiculite vs. rice hulls for SFC, and particle size for SFE. High yeast extract (1 g/l) produced more (P < 0.01) spores than low (0.3 g/l) for all culture systems. Carbohydrate (sucrose) at 20 g/l produced more spores than at 40 g/l for SFC. MgSO4 . 7H2O at 2 g/l was better than none for LF and SFC. For MF, LF, SFC, and SFE, respectively, the overall average numbers of spores per ml of medium were 0.53, 0.72, 0.28, and 0.073 X 10(7), while the highest numbers of spores were 1.25, 2.75, 1.52, and 0.46 X 10(7). Thus, the method of production cannot be decided at this stage but must await further studies of recovery and storage. RP SILMAN, RW (reprint author), USDA ARS,NO REG RES CTR,PEORIA,IL 61604, USA.

The red flour beetle has a single complex (HOM-C) representing the homologues of the ANT-C and BX-C in juxtaposition 1. Beetles trans-heterozygous for two particular HOM-C mutations spontaneously generate a large deficiency, presumably by an exchange within the common region of two overlapping inversions. Genetic and molecular results indicate that this deficiency spans at least the interval between the Deformed and abdominal-A homologues. In deficiency homozygous embryos, all gnathal, thoracic and abdominal segments develop antennal appendages, suggesting that a gene(s) has been deleted that acts to distinguish trunk from head. There is no evidence that beetles have a homologue of the segmentation gene fushi tarazu of similar genomic location and function. On the basis of the genetic tractability 2, convenient genome size and organization of Tribolium 3, and its relatively long phylogenetic divergence from Drosophila (> 300 million years), we have integrated developmental genetic and molecular analyses of the HOM-C. We isolated about 70 mutations in the complex representing at least six complementation groups. The homeotic phenotypes of adults 2 and lethal embryos lead us to believe that these beetle genes are homologous with the Drosophila genes indicated in Fig. 1.

Six irrigation treatments consisting of combinations of three rates of irrigation and two irrigation frequencies were used in assessing the influence of vegetative, flowering, and pod-filling periods on non-stressed canopy-air temperature differences versus vapour pressure deficit baselines and calculated CWSI values. Three distinct non-stressed baselines were determined and found to be related to the following crop morphological stages: (1) fully vegetative (few or no flowers); (2) flowering (few drying pods); and (3) pod development and maturation. Crop water stress index values across all treatments were highly and linearly correlated with stem water potentials. A less distinct curvilinear relationship existed between CWSI and leaf conductance. Use of the vegetative period non-stressed baseline to calculate CWSI values during flowering and pod-filling resulted in CWSI values 0.1 to 0.2 higher than those determined using growth-stage-dependent baselines. For irrigation scheduling, use of two baselines is suggested, one for the vegetative period and another baseline determined using pooled data from the flowering and podfilling periods.

The experiment was conducted in the San Joaquin Valley of California using a linear move sprinkler system which had been modified to apply water at 3 different levels of uniformity and 2 different scale lengths. The effects of these application uniformities on cotton growth and yield were evaluated at 4 different average levels of water application (0.7, 0.9, 1.1, and 1.3 times crop evapotranspiration, ET(c)). The leaf area index, plant height and total above-ground dry matter all exhibited a row-by-row response for the three lowest irrigation treatments. The seed cotton yields measured across rows did not follow the same pattern as the other plant parameters. Water applications far in excess of evapotranspiration often resulted in poor yields due to excess vegetative growth. In terms of above-ground total plant dry matter production, high water use efficiencies occurred with either short scale length or high application uniformities. Particularly in the 0.7 and 1.3 ET(c) treatments, cotton yields and growth were greater in the more nonuniform treatments than in uniform treatments due to the adequate (not excess or deficit) irrigation occurring in some rows of the pattern.

This may reduce crop yield. A simulation study was performed to evaluate sprinkler irrigated corn yield as affected by irrigation schedules resulting from three levels of ET underprediction. Four irrigation uniformity treatments, two soil types, and two weather scenarios in central Washington were also considered. Yield reductions ranging from 1 to 7% and from 8 to 27% were predicted when daily ET was underpredicted by 15% and 30%, respectively.

Merr. 'Bragg') plants were grown in large containers in open-top field chambers under five atmospheric CO2 concentrations (349-946-mu-l-l-1) and two water regimes. Rate of soil water depletion for the high CO2 treatments started to decrease under well-watered conditions during anthesis and by early pod formation under water-stressed conditions. During reproductive growth, normal and stressed plants at 349-mu-l-l-1 (ambient level) received irrigation water 29 and 12 times, respectively, compared with 21 and 9 times, respectively, at 946-mu-l-l-1 CO2. At both anthesis and pod fill, plants grown under CO2 enrichment exhibited greater leaf area. Nevertheless, water use per plant either remained constant (stressed plants at anthesis) or else declined (well-watered plants at pod fill; both moisture levels during pod fill) in response to CO2 enrichment. At pod fill, leaves of CO2-enriched plants generally displayed a higher stomatal resistance, except near the end of the sampling period when a sudden increase in resistance was observed under low CO2 owing to low soil water availability. Midday xylem potential for well-watered plants was greater than values for stressed plants and was unaffected by CO2 treatment. Under low moisture conditions, elevated CO2 had no effect on xylem potential at anthesis; however, during pod fill potential increased significantly with increasing CO2 concentration, as elevated CO2 decreased water use rates, lowering soil water stress. Alleviation of water stress during critical reproductive phases was strongly suggested. C1 SAN DIEGO STATE UNIV,COLL SCI,SYST ECOL RES GRP,SAN DIEGO,CA 92182.

A temperature-by-daylength experiment was conducted in the field on the Island of Maui, Hawaii (USA) at 282 and 640 m elevations during summer 1988 to examine the effects of daylength and temperature on leaf number, leaf area index (LAI), and grain yield of Pioneer hybrid X304C. Under high nutrient fertility and adequate water supply, plants were grown at natural daylength (12-13.5 h, control), control + 0.5-h, 14-, 17-, and 20-h daylengths. These daylengths were artificially produced by extending the natural daylength with 500-W lamps. For a 97-d period, mean maximum air temperatures were 26.8 and 27.8-degrees-C while minimum air temperatures for the same period were 20.1 and 16.4-degrees-C at the 282 and 640 m elevations, respectively. Longer days reduced mature leaf appearance rate and delayed tassel initiation and tasseling. Leaf tip appearance rate was unaffected by daylength but leaves took more thermal time for full expansion. Leaf area index in the 17- and 20-h daylengths was 7.0 at 77 d after planting, which was 1.8 times the LAI in the control and 14-h daylengths. Physiological maturity in the 17-h daylength was delayed by 33.5 and 38.5 d at 282 and 640 m, respectively. Maturity in the 20-h daylength was delayed by 41.0 and 48.5 d at 282 and 640 m, respectively. Grain yields and harvest indices at both elevations decreased significantly with increasing daylength. Overall, warm temperatures at 282 m enhanced the adverse effects of daylength on grain yield. C1 USDA ARS,IRRIGATED AGR RES & EXTENS CTR,PROSSER,WA 99350.

This study evaluated the recovery of residual labeled N fertilizer in the soil by corn (Zea mays L.) for two tillage systems and two fertilization methods. Five atom % N-15-enriched 28% urea-ammonium nitrate solution (UAN) at 224 kg N ha-1 was either surface-applied in the fall before any primary tillage or banded (knifed in) just before planting in the spring. Continuous corn was grown with either fall moldboard-plow (MP) or ridge-till (RT) systems. After the initial growing season, the recovery of residual labeled N in the soil by corn was determined for three consecutive growing seasons, and the soil profile was sampled periodically to measure residual N-15 in the organic and inorganic pools. One year after labeled UAN application, from 16 to 27% of the initial N-15 applied was found in the organic N pool and only 1% as inorganic N[NH4 + (NO2 + NO3)-N]. After four seasons, residual N-15 in the organic N pool ranged from 13 to 24%. Less than 0.5% remained as inorganic N. Regression analyses indicated that about 5 kg N-15 ha-1 yr-1 became available for both MP and RT systems with banded N, so the amounts were small. Total residual N-15 recovery by corn grain plus stover for three seasons ranged from 1.7 to 3.5%, and was greatest for spring-banded fertilizer (p = 0.01). Because the amounts of residual N-15 utilized were too small to affect corn growth, this N source appears to be negligible when considering corn-N needs.

Little data are available to guide a producer in selecting a legume that matches water and temperature conditions and produces acceptable growth and N2-fixation rates. The purpose of the experiment reported here was to provide such information. After a 14-d germination period at 20-degrees-C, we grew eight legume species at soil temperatures of 10, 20 and 30-degrees-C (+/- 2-degrees) for 105 d in a greenhouse. Daily water use was recorded, and plant dry weights were measured every 21 d. Initially annual species such as soybean [Glycine max (L.) Merr.] and fababean (Vicia faba L.) grew fastest at all temperatures. For the first 42 d at 10-degrees-C, white clover (Trifolium repens (L.), crimson clover (Trifolium incarnatum L.), and hairy vetch (Vicia villosa L.) also exhibited rapid growth. With warmer temperatures and longer growth periods, lespedeza (Lespedeza stipula L.) as well as soybean grew rapidly. At 20 and 30-degrees-C, soybean growth was often more than double that of most other species. Growth was maximal at 10-degrees-C for fieldpea (Pisum arvense L.), hairy vetch, and crimson clover; at 20-degrees-C for fababean and white clover; and at 30-degrees-C for soybean, sweetclover (Melilotus alba L.), and lespedeza. Average water-use rates and water-use efficiency generally paralleled growth, except water use increased and water-use efficiency decreased as soil temperature increased. These results indicate that growth and water use differed greatly among legume species, that each legume species has its own characteristic optimum growth temperature, and that this optimum temperature for a given species may change as growth progresses.

When they consider it they are not consistent in the methods they use. This study was conducted to: (i) find a method of testing for heteroscedasticity in nonreplicated whole plant growth data and (ii) determine the best weighting for such crop growth data. We developed seven different crop growth models with yield data collected during the growing season of five different crops (14 sets total, six with replicates). Next we performed tests for heteroscedasticity on model residuals and heterogeneity of variance tests on replicated data. Finally we conducted simulations to assess the confidence interval coverage of various weighted predictions based on one model fit to two of the replicated crop sets. Five of the models usually exhibited realistic growth responses throughout the growing season. All heterogeneity of variance tests were significant (P < 0.05) and most suggested a logarithmic weighting. In contrast, tests devised from groups of sequential residuals usually indicated a square root weighting but were generally not significant (P greater-than-or-equal-to 0.05). Simulations revealed that weighting was needed but that none of the variance models always adequately characterized the true variance. While not a good variance model, a linear trend in a model's squared residuals (P < 0.10) proved to be a sound test for heteroscedasticity in growth curves developed from nonreplicated data. Crop growth curves need to be weighted with an exact Box-Cox variance model when replicates are available and one intermediate between the logarithmic and square root model when replicates are unavailable.

These studies compared the pollination behavior/flower visitation times of both European honey bees (EHB) and AHB on small plots of cotton. While there were no measureable differences between the two types of bees as far as pollination effectiveness, the AHB used in the experiments became increasingly defensive (1988 vs 1987) and did not adapt to use inside screen cages. It is expected that, for use in many pollination applications, AHB colonies will have to be selected for gentleness before they can be moved and used to pollinate crops.

However, none of the children had ever presented with any of the classical vitamin B-6-deficiency symptoms. Treatment of three additional FHR children with 100 mg pyridoxine. HCl/d resulted in a moderate and transient elevation of their serum PLP concentrations, a dramatic elevation of their erythrocyte PLP concentrations, and no improvement in clinical condition. Serum or plasma PLP concentrations are an inappropriate index for determining vitamin B-6 status in people with FHR and perhaps in others with elevated alkaline phosphatase activity.

Any loss of isotopes in other products will introduce an error into these techniques. The body fat represents the largest potential sink for water H. H-2 sequestration into the carcass fatty acids was investigated in eight pigs labeled with (H2O)-H-2 for 21 days. r(CO2) was measured simultaneously in respiration chambers to allow an accurate assessment of the effect of H-2 sequestration on the estimated r(CO2). The fat content of the diet (1.63%), level of intake, and stage of maturity were all designed to give the widest possible range of sequestration effects. Four animals were restricted to their estimated maintenance requirement and four were allowed to feed ad libitum giving a range of weight gain from 100 to 650 g/day. This was reflected in the estimated error on r(H2O) (+0.42% in the restricted group and +2.52% in the fast-growing animals) and on r(CO2) (-1.30 and -7.59%, respectively). The error on the calculation of X using TLW was +0.03 units in the restricted group and +0.20 units in the fast-growing animals. The error of +0.2 on X propagates through to an underestimate of r(CO2) of approximately 4%, and since this is additive with the error on DLW the ultimate error on r(CO2) using TLW would be approximately -12%. Extrapolation of the errors to zero weight gain indicated that there would be very little turnover of the carcass fatty acids and no significant error on either r(H2O), r(CO2), or X in weight-stable animals. However, the errors on the isotopically derived parameters of r(H2O), r(CO2), and X can be substantial during rapid growth. It would therefore be prudent to consider the likely extent of water H sequestration when interpreting isotope flux data from DLW and TLW studies when there is growth or export of tissue, particularly when this involves fatty acid synthesis.

We reevaluated these functions and further characterized the inhibition of persistent BVD virus infection in neutrophils, using sensitive kinetic assays. In addition, the influence of in vitro incubation of neutrophils with recombinant bovine interferon gamma (rBoIFN gamma) and in vitro incubation of lymphocytes with recombinant bovine interleukin-2 was evaluated. Significant (P < 0.05) decrease in random migration under agarose, Staphylococcus aureus ingestion, cytochrome-C reduction, iodination, antibody-independent cell-mediated cytotoxicity, oxidant production, and cytoplasmic calcium flux were observed in neutrophils from cattle persistently infected with BVD virus, compared with noninfected control cattle. Incubation of neutrophils from noninfected controls with rBoIFN gamma significantly (P < 0.05) decreased random migration under agarose, cytochrome-C reduction, and cytoplasmic calcium flux. Neutrophils from cattle persistently infected with BVD virus also had decreased random migration under agarose after incubation with rBoIFN gamma; in addition, antibody-independent cell-mediated cytotoxicity, elastase release, and cytoplasmic calcium flux were significantly enhanced. The rBoIFN gamma induced significantly (P < 0.05) different effects on chemotaxis, cytochrome-C reduction, iodination, and cytoplasmic calcium flux of neutrophils from infected and control cattle. The rBoIFN gamma was more effective at improving the function of neutrophils from cattle persistently infected with BVD virus, compared with neutrophils from controls. Lymphocytes from infected cattle had decreased blastogenesis in response to phytohemagglutinin, concanavalin A, and pokeweed mitogen. Incubation of those lymphocytes with recombinant bovine interleukin-2, with no mitogen present, significantly (P < 0.05) increased incorporation of [H-3]thymidine. However, the response of lymphocytes to mitogen stimulation was not significantly increased by the presence of recombinant bovine interleukin-2, indicating that depression of in vitro lymphocyte blastogenesis in the cattle persistently infected with BVD virus is not attributable to decreased production of interleukin-2.

Isolates from aborted fetuses have been either subtype 1 or 2a, whereas subtype 2b viruses have not been associated with abortion. We assessed the abortifacient property of isolates representing each of the 3 BHV-1 subtypes by IV inoculation of heifers with the virus 25 to 27 weeks after breeding. Three heifers were given Cooper (subtype 1) isolate, 3 heifers were given FI (subtype 2a) isolate, and 5 heifers were given K22 (subtype 2b) isolate. All heifers developed fever and viremia 2 to 5 days after inoculation. Heifers given Cooper or FI isolate aborted between 17 and 85 days after inoculation. The 5 heifers given K22 isolate delivered full-term calves. Placenta was obtained from 4 of the 5 heifers, and K22 virus was isolated from each placenta. Four calves had BHV-1 neutralizing antibody in precolostral serum, with titer ranging from 1:4 to 1:512. RP MILLER, JM (reprint author), USDA ARS,NATL ANIM DIS CTR,POB 70,AMES,IA 50010, USA.

Analysis of ThFAS by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and protein immunoblot analysis confirmed earlier reports of a highly specific, low molecular weight antigen in this preparation; in contrast, other components of ThFAS were shown to react nonspecifically. Antibodies against the < 12-kD diagnostic antigen were detected in sera from 10 cattle and 4 swine inoculated with metacestodes of T saginata and T solium, respectively, but not in animals inoculated with Fasciola hepatica, Trichinella spiralis, Brucella abortus, or Toxoplasma gondii, or in noninoculated controls. Isolation and immobilization of the < 12-kD antigen on a hydrophobic transfer membrane resulted in development of an unambiguous dipstick assay capable of correctly identifying fully developed (10-week) experimentally induced infections in cattle and swine. In addition, the dipstick assay was highly specific for diagnosis of the disease in human beings, and offers the potential of distinguishing between human clinical cases of cysticercosis and taeniasis. A similar reactive antigen of diagnostic potential was also identified and isolated from T crassiceps and T taeniaeformis cyst fluids.

A nonlethal method to quantify dose response in cattle is needed to better estimate the toxicity of larkspur plants and the response of cattle to larkspur poisoning and to provide a basis for reference during studies. A numerical system of rating the clinical signs of larkspur poisoning was developed and used to describe the response of 10 Hereford cows given a repeated single daily dose of larkspur (Delphinium occidentale x barbeyi) by gavage. Larkspur poisoning resulted from a short-term cumulative effect, and a statistically significant increase in score was essentially maximal by 4 days. At the dose given, this effect did not persist for more than 4 days after cessation of dosing. Poisoning was most severe between 5 and 9 hours after dosing. Early signs of poisoning can be subtle and sometimes brief. The effect of larkspur poisoning can be exacerbated temporarily by exertion. Therefore, cattle could probably repeatedly consume an otherwise toxic daily dose, without manifesting marked signs of poisoning, if consumption decreased to a sufficient degree intermittently at 2- to 4-day intervals.

Tuberosum. The crossing of 2n pollen producing 1EBN clones as well as chromosome-doubled 1EBN clones with Gp. Tuberosum haploids was initiated to overcome this hybridization barrier. The screening of eleven 1EBN species, S. brachistotrichum, S. bulbocastanum, S. cardiophyllum, S. chancayense, S. commersonii, S. etuberosum, S. fernandezianum, S. jamesii, S. mochicense, S. pinnatisectum and S. trifidum, resulted in the identification of 2n pollen producers in eight of the species examined. Direct hybridization with Gp. Tuberosum haploids utilizing the above-mentioned crossing scheme was successful with S. chancayense and S. commersonii. The hybrids obtained, however, were male and female sterile. Abnormal microsporogenesis in the hybrids was postulated to be the result of an interaction between Gp. Tuberosum cytoplasm and nuclear genes contributed by the 1EBN male parent. Analyses of the growth of 1EBN species' pollen tubes in the stigma/style of Gp. Tuberosum haploids were also conducted. Interspecific incompatibilities were observed with the most severe forms found with the use of species in the Series Etuberosa. The use of the Endosperm Balance Number theory can aid in designing crosses which overcome barriers to successful endosperm development. Sterilities in the hybrids obtained as well as interspecific incompatibilities will also need to be addressed, however, before 1EBN species germplasm can be successfully utilized for the improvement of the cultivated potato.

The recollections of 50-year-old participants concerning perceived body size in comparison to peers during childhood (aged 5-7 years), adolescence (aged 10-18 years), and at ages 30, and 40 years were compared with physical measurements taken at these times. Correlations between perceived and actual body size at all ages from childhood through middle-age were moderate but significant (P < 0.005) and were influenced by gender and phases of physical growth (early and late adolescence). In general, accuracy of self-reports of current body size were not significantly better than recalls of body size up to 50 years earlier. Respondents' recall of various physiological events was also assessed. Females' actual and recalled year of menarche were correlated (r = 0.67; P < 0.0001). Age at menarche was recalled within 1 year of the actual event by 84% of the females. Fifty percent of both sexes recalled their year of maximal growth in height within 1 year and recalled the timing of their maturation (early, average, or late) in relationship to their peers equally well (P < 0.001).

Quantities of pheromone components in the emitted volatiles of H. subflexa from Florida were greatest during the 4th to 6th-h collection interval, whereas glands extracted with hexane at the 6th h contained the largest amounts of these chemicals. Phermone-release behavior (calling) was at its maximum during the interval of the 4th to 6th h. The chemicals detected in the volatile collections from H. subflexa were: (Z)-11-hexadecenal (Z11-16:Al), (Z)-9-hexadecenal (Z9-16:Al), hexadecanal, (Z)-11-hexadecen-1-ol acetate, (Z)-9-hexadecen-1-ol acetate, (Z)-7-hexadecen-1-ol acetate, (Z)-11-hexadecen-1-ol (Z11-16:OH), and (Z)-9-hexadecen-1-ol. The pheromonal chemicals of H. virescens from Mississippi occurred in greatest quantity in emissions collected during the 6th to 8th h and 8th to 10th h intervals, and in the glands extracted at 8 and 10 h into the scotophase. H. virescens females produced and released phermone over a broader period of time than H. subflexa females. The chemicals detected in the volatile collections from H. virescens were: tetradecanal (14:Al), (Z)-9-tetradecenal (Z9-14:Al), 16:Al, Z9-16:Al, Z11-16:Al, and Z11-16:OH. The alcohol/aldehyde and acetate/aldehyde ratios present in the extracts of glands from H. subflexa varied during the dark period, whereas those ratios in H. virescens were relatively constant. The ratios, relative to Z11-16:Al, of the acetates and of Z9-16:OH in extracts of glands of H. subflexa from Florida differed significantly from those of females from the U.S. Virgin Islands; the U.S. Virgin Islands glands contained 2.2 times more total amount of pheromonal chemicals than those from Florida. The ratio of Z11-16:OH, a critical chemical in sexual communication of H. subflexa, did not differ between the gland extracts obtained from two populations. Heliothis virescens from Mississippi and U.S. Virgin Islands contained similar amounts of total pheromonal components within their glands, and the relative ratios of components were the same between the populations.

When grown aerobically, Candida wickerhamii, C. guilliermondii, and C. molischiana metabolized cellodextrins of degree of polymerization 3 to 6. C. wickerhamii and C. molischiana also fermented these substrates, while C. guilliermondii fermented only cellodextrins of degree of polymerization less-than-or-equal-to 3. Debaryomyces polymorphus, Pichia guilliermondii, Clavispora lusitaniae, and one of two strains of Kluyveromyces lactis metabolized glucose, cellobiose, and cellotriose when grown aerobically. These yeasts also fermented these substrates, except for K. lactis, which fermented only glucose and cellobiose. The remaining species/strains tested, K. lactis, Brettanomyces claussenii, B. anomalus, K. dobzhanskii, Rhodotorula minuta, and Dekkera intermedia, both fermented and aerobically metabolized glucose and cellobiose. Crude enzyme preparations from all 14 yeast species or strains were tested for ability to hydrolyze cellotriose and cellotretose. Most of the yeasts produced an enzyme(s) capable of hydrolyzing cellotriose.

Moon Lake (10.1 km2), an oxbow of the Mississippi River, receives drainage through a series of wetlands from farmland intensively cultivated in cotton, soybeans, and rice. All watershed components were contaminated by DDT. Ten years after being banned, SIGMA-DDT was present in soil, wetland and lake sediments, surface water, and fish. Residual insecticide concentrations were significantly higher in aqueous/sediment phases of surface waters during the winter/spring wet season than during dry season. This period of maximum runoff corresponded to minimum ground cover and maximum soil disturbance. Increased concentrations during periods of runoff emphasizes the magnitude of the DDT source that remains in soil (xBAR = 369.3-mu-g/kg) and indicates the importance of watershed management practices on long-term water quality. Current use insecticides were not detected in soils. In other watershed components, they were found less frequently, more sporadically, and in lower concentrations than persistent insecticides. However, the detection of these acutely toxic insecticides, especially methyl parathion, in fish tissue showed that these insecticides have sufficient persistence for uptake and, perhaps, bioaccumulation.

In order to assess such relationships we have examined allele frequencies of 8 different RFLPs within or adjacent to the apo A-I, C-III and A-IV gene complex on the long arm of chromosome 11 (MspI, 5' to the apo A-I gene; MspI, within the apo A-I gene; PstI, 3' to the apo A-I gene; SstI, 3' to the apo C-III gene; PvuII, within the apo C-III gene; PvuII, 5' to the apo C-III gene; XbaI, within the apo A-IV gene; and XbaI, 3' to the apo A-IV gene) in 202 patients with CAD (50% narrowing of one or more coronary arteries) prior to age 60 and 145 normal controls. None of the allele frequencies of these RFLPs were significantly different in cases as compared to controls. With regard to associations with plasma lipids and apolipoprotein levels, the rare allele determined by the absence of the PstI site was associated with elevated triglyceride levels (P < 0.05) in cases, but not in controls. In contrast, the rare MspI allele 5' to the apo A-I gene was associated with elevated triglyceride levels (P < 0.05) in controls but not in cases. In both cases and controls, subjects with the uncommon SstI allele had triglyceride levels that were 9 and 38% higher than in those without this allele. These differences were significant (P < 0.05) only in controls. Our data indicate that the rare allele determined by the SstI site within this gene complex deserves further study in order to understand its association with elevated triglycerides in Caucasian populations. However, at the present time all these DNA markers lack sufficient specificity to be clinically useful for CAD risk assessment. C1 NEW ENGLAND MED CTR HOSP,DEPT MED,DIV CARDIOL,BOSTON,MA 02111.

We germinated Fiskeby V seeds at 20 C, then randomly assigned plants to either an 18 C or 25 C controlled environment chamber until they had produced mature seeds. Characteristics of the seedlots produced at 18 and 25 C were then compared in controlled environment chambers with three different thermal regimes and, also, in field trials. Mean seed size and emergence rate did not differ between seedlots. When grown at 25 C in a controlled environment, and when grown in the field, plants grown from the 25 C-grown seedlot had greater axillary stem weight than the 18 C-grown seedlot, at each of three growth stages. Total leaf area and dry weight were greater for the 25 C-grown seedlot than for the 18 C-grown seedlot at one growth stage, when grown in the controlled environment at 25 C and in the field. The results indicated that environment of the parent plants had an effect on the morphology and growth rate of the subsequent generation and indicate that caution should be used in inferring genetic differences between parent populations from morphological differences in the progeny.

Comparative morphological development of the peg, ovary, and ovule was undertaken in two A. hypogaea L. cultivars, cv NC 6 and cv Argentine, and two closely related diploid Arachis species, A. duranensis and A. stenosperma, to determine if probable impediments could be detected. Analysis showed that there were significant differences among the four genotypes with respect to length of both basal and apical locules. The A. stenosperma basal locule was the longest but decreased slightly during development, while other genotypes had a positive linear slope. Apical locule growth patterns varied, with wild species showing curvilinear growth. Basal and apical ovules were nearly the same size for all genotypes except cv NC 6, which was longer and grew more rapidly. Basal and apical embryos reached the eight-cell phase in all genotypes by d 5. Embryo growth of the basal ovules was linear, while that of apical ovules was quadratic, tapering off after 72 h. Cv NC 6 was longer and grew more rapidly than the other genotypes and A. duranensis had the smallest embryos. Embryo width showed a linear decrease in all genotypes, with the rate greatest in cv NC 6. Peg growth was initiated within 24 h after fertilization in all genotypes, at which time only A. duranensis had a significantly faster growth rate. Differences in various component growth rates controlled from information supplied by male gametes and female egg and/or polar nuclei could conflict with each other and restrict or accelerate growth in such a manner as to induce abortion.

Salinization by 80 mol m-3 NaCl (from the 10 mol m-3 control concentration) slowed shoot development. The lengthening of the plastochron because of salinization was evident in rates of leaf expansion, frequency of leaf emergence, and growth rate of the whole shoot. The plastochron effect on shoot development was sufficient to account for a 33% reduction in biomass of the shoot, equaling the entire growth inhibition measured during the first week following salinization. A second effec, reduction in maximum leaf size, could be measured after 2 more wk of plant growth. A 50% reduction in fresh weight of fully mature leaves of salinized plants was evident in leaves already beyond the most rapid phase of expansion at the time of salinization. Curtailment of the slow phase of leaf expansion seems, therefore, to reduce maximum leaf size. This cultivar lends itself to nondestructive growth study because of its rapid growth, high rate of leaf emergence, the open access to its leaves, and the absence of a significant contribution by the stem to shoot biomass. Mathematical reconstruction of the shoot allows comparison with results from destructive studies measuring growth of the bulked shoot.

There were significant differences in seed weight and seedling biomass between the two locations. Seed from the Methuselah Grove was lighter and Methuselah seedling biomass was lower at all four harvest dates. However, regression analyses did not identify any relationship between tree age and any variable. C1 UTAH STATE UNIV,DEPT FOREST RESOURCES,LOGAN,UT 84322.

The larvae feed below ground on woody and non-woody plant tissues for 2 years before maturing. It was found at 18 localities across New England and Nova Scotia during the summers of 1987 and 1988. On Whiteface Mt., New York, and Mt. Moosilauke, New Hampshire, larvae were absent to uncommon at low (500 m) and high (1300 m) altitudes, but common to abundant in red spruce - balsam fir associations at 700, 900, and 1100 m. During September 1987, larval populations were estimated at 56 000 and 312 000 per hectare in soils at 900 m on Whiteface and Moosilauke, respectively. Dense populations occurred locally, e.g. 27 larvae were recovered from a single 0.25-m2 soil pit at 900 m on Moosilauke. By June 1988, larval numbers on Whiteface and Moosilauke had declined by 51% and 72%, respectively. Seedlings and mature trees of both spruce and fir were damaged by larval feeding on bark and cambium. Seedlings were girdled; mature trees had wounds paralleling the root axes.

Cross-correlation analysis indicated that the catches of corn earworm moths in pheromone traps were closely associated with egg numbers in seven of eight fields with a time differential varying between - 1 to + 2 days. Cross-correlation peaks for new silks versus eggs occurred with time differentials being mostly positive, indicating that corn earworm egg numbers reached a maximum after corn produced large numbers of fresh silks on ears. There was a weak but significant linear relationship between egg numbers and corn earworm catches in pheromone traps when corn was in the whorl stage of growth. A stepwise regression model of the form: log (eggs/ha + 1) = 3.71 + 0.22*log(S + 1)*log(T + 1) - 0.3*log(S + 1), where S = numbers of corn ears with new silks per hectare, and T = mean corn earworm moths per trap, explained 52.5% of the variance. These results emphasize the mediating effects of fresh silks on corn earworm oviposition on corn. C1 PEST MANAGEMENT RES UNIT,COLLEGE STN,TX 77843.

Research was conducted in 2 separate years. Laboratory-reared O. nubilalis eggs or larvae were placed on the plant during either the whorl stage (V6) or the pollen-shedding stage (R1) to simulate first- and second-generation O. nubilalis oviposition periods, respectively. Efficacy was determined by measuring the length of European corn borer tunnels in the corn stalk at harvest time. In the 1st year, first generation, and second generation (of 2nd year) B. thuringiensis and B. bassiana alone and in combination caused significant reductions in tunneling compared with that in the check populations. There were no significant differences in tunneling between any treatments in the second-generation study of year 1. Bacillus thuringiensis and B. bassiana were independent of each other in their suppression of insects. Tunneling by the naturally occurring second-generation larvae (year 2) was recorded to determine if B. thuringiensis and B. bassiana applied in the V6 stage persisted in the plant. Pith samples were excised from nodal plates 7-10 of the corn stalk to determine the incidence of B. bassiana. There was a significant correlation (r = -0.376) (P less-than-or-equal-to 0.05) between the occurrence of B. bassiana in the corn plant and tunneling by second-generation larvae. These data indicate that B. bassiana placed in the whorl of the corn plant may provide season-long suppression of O. nubilalis. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT ENTOMOL,AMES,IA 50011.

The outer aperture formed between the stomatal guard cells was bordered by cuticular ledges, 1.2-5.3-mu-m wide. These were composed of a matrix of electron-dense fibrils supporting an autofluorescent amorphous outer layer, homologous to the cuticle. This layer of cuticle lined the ventral walls of the guard cells and extended into the substomatal chamber. During stomatal development, as the guard cells separated, the outer cuticular layer covering the incipient aperture stretched and split, forming stomatal lips. These lips, 0.2-1.4-mu-m wide, were oriented horizontally, upright, and folded back from the ledge in TEM thin sections. In cryopreserved stomata, the lips were generally oriented upright regardless of whether the outer aperture was open or closed. Previous studies have implicated that stomatal lips may function to signal appressorium formation in urediniospore germlings of Uromyces appendiculatus. This study indicated that dimensions of the lips were within the parameters required to induce appressorium formation on artificial membranes. Other components of the stomatal architecture may also be involved in the induction of appressorium formation. C1 CORNELL UNIV,NEW YORK STATE AGR EXPT STN,DEPT PLANT PATHOL,GENEVA,NY 14456.

Red alder, with its high degree of host specificity and paucity of fungal symbionts, provides an ideal model for studying these attributes. Eleven morphologically recognizable types of ectomycorrhizae were characterized from field-collected root material, greenhouse soil bioassays, and laboratory syntheses. Most mycobionts were basidiomycetes, as evidenced by abundant clamp connections present in the mantle and extramatrical hyphae. Seven mycobionts identified to species included Alpova diplophloeus, Thelephora terrestris, Lactarius obscuratus, Cortinarius bibulus, Laccaria laccata, Hebeloma crustuliniforme, and Paxillus involutus. Many of the ectomycorrhizae collected in the field appeared to have more than one mycobiont present in the mantle. Root tips could generally be categorized into either flexuous or succulent morphological types. The flexuous types were long, thin, indeterminate in growth, with an acute root apex, and the mantle and Hartig net in longitudinal section were not well formed near the root apex. The succulent types were short, thick, determinate in growth, with a rounded root apex, and the mantle and Hartig net in longitudinal section were well formed near the root apex. Additional characteristics important in distinguishing among red alder ectomycorrhizal types included color, extent of extramatrical hyphae development, mantle surface characteristics, and selected microchemical reactions. Mantle thickness was highly variable and not useful in characterization. Hartig net development was shallow, and regardless of mycorrhizal origin, rarely extended beyond one epidermal cell layer.

No evidence of permineralization was observed. Wood with rounded cells, thick secondary walls, and intercellular spaces was common in all samples. Secondary walls were eroded and swollen. A transition from an organized secondary wall, with altered but visible microfibrillar structure, to an electron-dense, amorphous material was evident in cell walls. The amorphous material appeared to form primarily in the secondary walls near cell lumina and along cracks that extended into the walls. The middle lamellae were often expanded in size and had convoluted shapes. Hemicellulose degradation appeared to precede cellulose degradation. Samples exhibiting cell walls with increased amorphous material had the greatest lignin and lowest cellulose concentrations. Hemicellulose concentration was extremely low in all Eocene and Paleocene samples. The lignin content of Miocene wood was 47.9%, whereas the Eocene and Paleocene samples ranged from 66 to 84%. Tracheids from extensively degraded samples were distorted and collapsed, and in some cases the cells appeared compressed together. Although the residual amorphous middle lamellae and secondary walls were fused together, the outlines of original cells were visible. Chemical analyses and ultrastructural data indicated that a nonbiological degradation was responsible for the deterioration of the arctic fossil wood samples.

Four to six hours after anastomoses formed, the strains were preserved using freeze-substitution and observed using transmission electron microscopy. Hyphal anastomoses between Ep-50 and Ep 15-7-7 showed complete cytoplasmic continuity, with microtubules and mitochondria extending through the fusion aperture. Spherical, membrane-bound virus-like particles, measuring 50-90 nm in diameter, were located in the Ep-50 hypha, the Ep 15-7-7 hypha, and the short anastomosis bridge between them. All anastomoses between the compatible strains involved a hyphal peg that grew toward a swelling that developed on the receiving hypha. Fusion took place between the swelling and the lateral wall of the peg. Anastomoses between the incompatible strains showed cellular collapse and cytoplasmic degeneration that extended away from the anastomosis area in hyphae of both strains. Because of this, vegetative incompatibility would seem to be a formidable barrier to hypovirulence conversion and biocontrol of C. parasitica.

Sample trees represented three seed sources (Clark County, AR; Livingston Parish, LA; and Onslow County, NC), each of which had been planted at three installations (Arkadelphia, AR; Poplarville, MS; and New Bern, NC) located in the general geographic area where one of the seed sources had been collected. Stem analysis was facilitated by the development of a staining technique that enhanced recognition of the boundaries between individual height-growth cycles and between years. Both annual height growth and number of cycles produced varied with tree age, seed source, and installation. Number of cycles produced per year ranged from two to seven; maximum annual production of cycles per seed source was achieved between ages 3 and 10 years. Even between ages 30 and 35, trees still exhibited polycyclic behavior, producing two to five cycles annually. Annual height growth was greatest between ages 4 and 15; height growth declined with age more rapidly than annual number of cycles. The relationship at each installation between cumulative height and cumulative number of cycles showed that the tallest seed source (Onslow in all cases) was the one that had produced the greatest number of cycles. Shorter trees at the poorest site resulted from lower numbers of cycles produced and, particularly after the production of 50 to 65 cycles, shorter mean cycle length. For all three seed sources, mean height was greatest at the installation where the trees produced the most cycles. Height-growth curves for two of the installations crossed, demonstrating differences in height-growth patterns related to site characteristics.

Although normal yield tables have come under intense criticism, critics have generally ignored the relative density change equation. If a yield table captures the "true" relations between volume, age, and site for a species, the relative density change equation can be a simple function of initial relative density and age. If a yield table does not capture the true relations between volume, site, and age, the inadequacy can be overcome by developing more complex relative density change equations, i.e., by transferring representation burden to the change equation. Introduced in the present paper is the concept of an identity yield table (all entries are one), wherein the entire burden of representing the relations between volume, site, and age is transferred from a density standard to a relative density change equation. Modern whole stand (net) growth models are equivalent to historical relative density change equations based on identity yield tables. The conjecture of a continuum of methods to estimate growth from near-normal to empirical to identity yield tables, each with an appropriate relative density change equation, and each equally accurate, is tested on Wisconsin jack pine (Pinus banksiana Lamb.). The empirical yield table and its relative density change equation were more biased than near-normal and identity-based projection systems.

Variance equations estimated three error components: covariances propagated through predictor variables, covariances from estimated regressor coefficients, and covariances between regressor coefficients and variables. A separate Monte Carlo process was used to estimate the total variance in projected variables caused by simultaneous perturbations in values of initialization variables and in regressor coefficients. Variances estimated by these two procedures were compared over five consecutive projection periods for six variables in a forest growth simulation model. While results agreed closely for the variance in mean stand diameter, disparities increased for other variables later in the model estimation sequence. Disparities were attributed to differences between the populations used in both variance estimation procedures and to possible violations of Taylor series assumptions in the variance estimation equations.

Functionality was assessed by adding fractions to a base (reference) flour at a level of 1% (protein to flour weight) and measuring mixograph peak development times and loaf volumes in an optimized baking test. Protein composition was measured by sodium dodecyl sulfate-polyacrylamide gel electrophoresis under reducing and nonreducing conditions, followed by densitometry of the stained patterns. The pattern areas of reduced fractions, which corresponded to total proteins, were divided into subareas representative of five main protein classes: high molecular weight glutenin subunits; omega-gliadins; low molecular weight glutenin subunits; alpha-, beta-, and gamma-gliadins; and albumins plus globulins. Also, the proportion of glutenin in each fraction was estimated for some cultivars as the difference between the total area under the densitometer tracing of the pattern of a fraction reduced (total proteins) and the total area under the densitometer tracing of the pattern of the same fraction unreduced (from which essentially only monomeric proteins enter the gel). The proportion of high molecular weight glutenin subunits in the parent glutens increased in accordance with dough strength and, with one exception, loaf volume. As the fraction number increased, the proportion of glutenins generally paralleled the increases observed in dough development time and loaf volume, except for some of the later fractions.

A field study was conducted to compare Pima cotton (Gossypium barbadense L.) with upland cotton (G. hirsutum L.) as a pollen source for hybrid seed production using male-sterile upland seed parents. Male-sterile cotton flowers were hand pollinated with either upland or Pima cotton pollen. The number of pollen grains per stigma and the resulting number of seeds per boll were evaluated using covariance analysis. In each of 3 yr the bolls produced from pollen of upland cotton produced more seeds per boll than did those produced from Pima pollen. Adjusted least square means indicate an advantage of four to seven seeds per boll with upland pollen. The conclusion is that more pollen grains per stigma are needed to set an equal number of seeds when using Pima pollen compared with using upland pollen.

Twenty-two isozyme loci and one additional locus (P), scored by glume color on the cob, served as genomic markers for detecting QTLs affecting 21 quantitative traits in six F2 populations derived from five elite inbred lines (B73, Mo17, Oh43, Tx303 and T232). A significant effect was found to be associated with at least one chromosomal region for every trait analyzed in the six elite-cross F2 populations. Despite the greater morphological similarity of the elite lines compared with lines used in previous studies, the number of significant associations detected was similar to results of previous studies, after accounting for differences in population size. Up to 15% of the total phenotypic variation could be explained by factors linked to a single marker locus. The type of gene action at each significant association was determined and the results showed that broad generalizations can be made regarding the gene action for groups of traits. Comparisons made between populations showed that certain areas of the genome consistently affected specific traits: i.e., ear length and grain weight at Amp3 on Chromosome 5 and ear circumference at Glu1 on Chromosome 10.

The sequential method involves cycling early-generation selections through different environments, as opposed to practicing selection at the same location each year. To evaluate this method, a cooperative peanut (Arachis hypogaea L.) selection study was conducted in Georgia, North Carolina, and Oklahoma. Pedigree and sequential selections and single seed descent were compared each of 3 yr for yield and leafspot [Mycosphaerella arachidis Deighton (anamorph: Cercospora arachidicola S. Hori). and Mycosphaerella berkeleyi Jenk. (anamorph: Phaeoisariopsis personata Berk. & M.A. Curtis/Arx)] resistance. Sequential selections were comparable to or significantly better than the pedigree selections in leafspot rating and yield performance. Individual sequential selections were also found with combined leafspot resistance and high yield. In general, the sequential selection method proved to be an alternative approach for peanut breeding. C1 USDA ARS,DEPT AGRON,COASTAL PLAIN EXPTL STN,TIFTON,GA 31793.

Merr.] seed yields often show a negative association with seed protein. The objective of this study was to determine if this association could be minimized by crossing a high and a normal protein line of equal seed yield. An F2 population of 1000 plants was grown. Plants were harvested individually and seed evaluated for oil content using the nuclear magnetic resonance technique. Two bulk populations were developed: one included the 8% having the highest oil and the other the 8% having lowest oil. With the high negative correlation between seed protein and oil, the low oil population was expected to provide lines having high seed protein concentration. The two populations were advanced in bulk through the F6 generation, after which 200 plants were harvested individually from each population and 200 F7 lines grown from each. The F7 lines were harvested individually and seed analyzed for seed protein and oil. The 18 lines having the highest protein and the 18 lines having the highest oil were selected for further evaluation in replicated trials. Lines were evaluated in five environments for seed yield, protein, and oil. The overall mean seed yield of the high protein lines averaged 6% less than the overall mean of the lines selected for high oil; however, when seed yield of the two highest protein lines at each environment were compared with the two highest oil lines, the high protein lines had a 1% advantage in seed yield, an 18% advantage in seed protein, and a 20% reduction in oil. The results demonstrate the potential for developing soybean lines high in seed protein and equal in seed yield to lines having high oil content.

In a greenhouse trial, forage quality of leaves and stems of the nine germplasms was compared when grown in a common environment and harvested at the same phenological stage. Germplasm sources (and representative cultivar) tested were: Indian (Sirsa #9), African (African), Peruvian (Hairy Peruvian), Flemish (DuPuits), Turkistan (Lahontan), Chilean (Kansas Common), M. varia Martin (Grimm), Ladak (Ladak), and M. falcata L. (Anik). Leaves of germplasm sources differed for concentrations of neutral detergent fiber, cellulose, crude protein, true in vitro digestible dry matter, and p-hydroxybenzaldehyde, vanillic, p-coumaric, ferulic, and sinapic acids. Stems of germplasm sources differed for concentrations of NDF, hemicellulose, CEL, TIVDDM, and p-hydroxybenzoic, syringic, p-coumaric, and ferulic acids. Results indicate that alfalfa germplasm sources differ in nutritive value of leaves and stems. C1 KANSAS STATE UNIV AGR & APPL SCI,USDA ARS,MANHATTAN,KS 66506.

Merr.]. To select for increased N2 fixation in soybean, plant breeders need to identify those morphological traits associated with the fixation process. The objectives of this study were to classify cultivars (Maturity Groups V through IX) and breeding lines for nodule weight, nodule number, and shoot and root weight at the R3 to R4 stage of development under field conditions in Gainesville, FL. Of the 100 soybean genotypes screened in 1983, 17 were selected for more detailed study in 1984 and 1985. 'Hardee', 'Centennial' and F81-7313 ranked among the genotypes with the greatest nodule weight and number; and these rankings were consistent across years and locations tested. Environmental stability analyses showed that those lines with the greatest mean nodule weight also had the greatest positive response to favorable environments. Nodule weight and number were highly correlated traits (r > 0.84). Root and shoot weight had moderately positive correlations with nodule number and nodule weight.

Over the last few years, numerous monosomic addition (MA) stocks were derived from interspecific backcrosses of Gossypium sturtianum J.H. Willis (2n = 2x = 26, C1 genome) with G. hirsutum L. [2n = 4x = 52, (AD)1 genome] as recurrent parent. Using 10 MA plants of varied pedigrees from this project, our objectives were to (i) identify and characterize different MA stocks, (ii) determine the phenotypic effect of each addition chromosome, and (iii) estimate the frequency of (AD)1-C1 recombination. We identified 4 distinct G. sturtianum MA types among the 10 analyzed, and have temporarily designated these as C1-A, C1-B, C1-C, and C1-D. The C1-A, C1-B, and C1-D MA stocks differed phenotypically from the recurrent parent, while the C1-C MA stock was phenotypically indistinguishable from the recurrent parent. None of the MA chromosomes was pollen transmissible, but all were ovule transmissible in vivo. Frequencies of ovule transmission from the MA chromosomes ranged 13.7% for C1-B to 77% for C1-A. Cytogenetic analyses of the parental stocks and their backcross progenies revealed low but nonetheless increased frequencies of abnormal meiotic chromosomal configurations, possibly due to previous intergenomic recombination, the meiotic disturbances, or both. Genetic data to substantiate recombination have not yet been obtained, but chiasmata were observed at a frequency of 1.7% per meiotic C1 chromosome in the MA stocks, indicating that recombination with chromosomes of G. hirsutum is occurring, albeit infrequently. The establishment and characterization of these four MA stocks will facilitate development of dispersed repetitive genomic probes for the C1 genome, analysis of interspecific C1-to-(AD)1 genomic introgression, and the derivation of additional C1 MA stocks.

The germplasm line WC-12NL (nectariless, okra leaf, and early maturing) and 'Deltapine 61' (nectaried, normal leaf, and later maturing) were grown at Maricopa, AZ, and Brawley, CA, for three seasons. Irrigation water was terminated and plots were defoliated earlier than normal, a practice that favored the early-maturing line. Insecticides were applied as needed, based on PBW egg infestations of cotton bolls. The major objective was to determine whether insecticide use can be reduced or eliminated by growing WC-12NL. Other objectives were to compare WC-12NL with Deltapine 61 for PBW resistance, yield, earliness, and fiber properties; to study location and seasonal effects; and to determine whether the growth-regulating chemical ethephon (2-chloroethylphosphonic acid) would cause bolls to open earlier. The mean number of insecticide applications was 41% lower for WC-12NL than for Deltapine 61. First and last application dates averaged 21 d later and 10 d earlier, respectively, for WC-12NL. WC-12NL had significantly less seed damage caused by PBW, yielded significantly more lint, was significantly earlier, but had inferior fiber properties compared with Deltapine 61. Ethephon treatment increased earliness of Deltapine 61 but did not affect that of WC-12NL, probably because it was applied too late. Location and seasonal effects and numerous interactions occurred, but did not alter the main conclusion that a cotton line such as WC-12NL (but with improved fiber properties) could be valuable in areas where PBW is a problem.

Six tropical maize populations ('Caingang-BOV 78', 'Negro de Tierra Caliente-GUA146', 'Lenha-RGS XX', 'Negro de Tierra Caliente-GUA159', 'Negrito', and 'Costeno-VEN 453') and five testers ('Zapalote Chico' PI 217413, 'B14A', 'Oh43', 'CM105', and 'A654HT') were used to determine which tester most effectively reduced time to flowering when crossed with tropical populations and to determine whether there was a population x tester interaction for genes controlling photoperiod sensitivity. Evaluations were carried out in 1987 and 1988 under decreasing photoperiod (18-9 h of light) in the growth chamber for the populations, testers, and testcrosses and also in the field for the testcrosses. Three field environments, two in Iowa and one in Puerto Rico, were utilized. In the growth chamber, days to tassel emergence differed among populations and testers per se and among testcrosses. Tassel emergence for populations and testers occurred from the 12-h to the 9-h photoperiod. The tropical population least sensitive to photoperiod was Negro de Tierra Caliente-GUA146, while CM105 was the least sensitive tester. There were significant differences among testcrosses in the combined analysis for days to pollen shed for the field environments. Two testers, CM105 and A654HT, produced the earliest testcrosses over all environments. There were significant differences in the contribution testers made toward earliness in tropical population testcrosses in temperate environments. C1 USDA ARS,FIELD CROPS RES UNIT,AMES,IA 50011.

The purpose of this preliminary study was to examine leaf-gas exchange and related leaf traits among winter wheat genotypes in the field to characterize genotypic-related variation in photosynthesis and water-use efficiency. Fifteen winter wheat genotypes, 13 developed in the central and southern Great Plains of the USA and 2 from the USSR, were planted into a Nunn clay loam (fine, montmorillonitic, mesic Aridic Arguistoll) near Fort Follins, CO, in September 1987. Leaf-gas exchange measurements were performed approximately weekly on flag leaves of all genotypes from 27 May (early heading stage) through 20 June 1988. Significant genotypic effects were found for photosynthetic rate per leaf area (CER), leaf conductance (g(s)) leaf water-use efficiency (WUE(g) = CER/g(s)), the ratio of intercellular [CO2]/ambient [CO2], specific leaf weight, and chlorophyll concentration. Among the genotypes with the lowest water use efficiencies were the two old, large-leaved Soviet genotypes and the two oldest Great Plains genotypes surveyed, 'Vona' and 'Sturdy'. Negative associations of leaf size with CER and WUE(g) were mostly due to differences in leaf size and CER between the relatively small-leaved Great Plains genotypes and the large-leaved Soviet genotypes. Significant variation for WUE(g) among the winter wheat genotypes was due to genotypic-related differences in both photosynthetic capacity and g(s).

Filter paper exclusion of PEG and water vapor loss from unsealed containers change the solution water potential from the initial PEG solution potential. The influence of water potential change attributable to PEG exclusion and vapor loss were evaluated with sideoats grama [Bouteloua curtipendula (Michaux) Torrey], buffelgrass [Cenchrus ciliaris L.], Lehmann lovegrass [Eragrostis lehmanniana Nees], and kleingrass [Panicum coloratum L.]. Exclusion of PEG by filter paper substrates significantly influenced total germination and germination rate for three of the four species. The absence of a measurable effect on Lehmann lovegrass was attributed to low germination at lower water potentials. Oscillating substrate water potentials originating from water vapor losses and subsequent additions produced significantly greater total germination and faster germination rate when compared to a constant water potential. Polyethylene glycol filter-paper exclusion and water vapor loss from PEG solutions are significant influences that must be considered when conducting seed germination investigations.

EFFECTS OF WATER DEFICIT ON PEANUT SEED QUALITY SO CROP SCIENCE LA English DT Article ID DORMANCY AB The peanut (Arachis hypogaea L.) crop is frequently subjected to water deficit during the growing season. This study was conducted to determine the effect of water received by the crop on the germinability and vigor of the subsequent seed generation. Two peanut genotypes, 'Comet' and breeding line OK-FH15, were grown under both rainfed and irrigated conditions on a Teller sandy loam (fine, mixed, thermic Udic Argiustoll) soil in 0.91-m wide rows using standard agronomic practices. Pods were harvested, dried, and shelled. Only mature seeds (those with smooth seed coats and riding at least a 5.95 by 19.05 mm slotted screen) were used in the tests. Seeds were germinated at 29 +/- 1-degrees-C in 2-L flasks fitted with two sheets of 15.0-cm Whatman no.5 filter paper. Ethylene and CO2 were quantitatively determined by gas chromatography. Germination ranged from 94 to 100%, but was lowest for seeds produced under water deficit. Maximum C2H4 production occurred at 22 to 24 h of germination during hypocotyl-radicle emergence. Carbon dioxide production was maximized 24 h later, or rose slowly thereafter. Water deficit during seed production affected both C2H4 and CO2 production during subsequent germination. The most consistent response to water deficit was reduction in the fraction of rapidly growing seedlings (those with hypocotyl-radicle longer than 20 mm at 72 h of germination). Thus, water deficit during seed development affects subsequent growth of seedlings and could pose a problem in establishment for the succeeding crop. A minimum of 500 mm of water was necessary to produce a crop of seeds with high potential for germination and a high proportion of vigorous seedlings.

Differences in proteolysis among species have been observed, but plant characteristics associated with these differences have not been well defined. This study was conducted to determine if tannins play a role in modifying N transformations associated with the preservation of forage legumes as silage. In 1987, 12 legume genotypes (representing six species) were field grown and analyzed for tannin concentrations and pre- and post-ensiling dry matter (DM), pH, and N forms. In 1988, 18 genotypes (representing seven species) were evaluated in a similar manner. Tannin concentrations ranged from 0 to 27 g tannic acid equivalents kg-1 DM in 1987 and 0 to 31 g in 1988. Dry matter concentration, pH, and concentration of total N, soluble nonprotein N (SNPN), free amino acid N, and ammonia N of fresh and ensiled herbage were within the range of previous literature reports for forage legumes. The proportion of total N in the form of SNPN after 35 d ensiling ranged from 32 to 73% in 1987 and 26 to 69% in 1988 and was negatively related to tannin concentration (r2 = 0.75). Within sericea lespedeza [Lespedeza cuneata (DumCours) G. Don], the only species with substantial variation for both tannin and silage SNPN concentrations, r2 values were 0.81 in 1987 and 0.88 in 1988. Red clover (Trifolium pratense L.) and cicer milk-vetch (Astragalus cicer L.) did not contain measurable levels of tannins, but exhibited lower proteolysis than alfalfa (Medicago sativa L.). These results suggest that tannins play a major role in limiting proteolysis in some legumes during ensiling, but other factors also are involved. C1 USDA,US DAIRY FORAGE RES CTR,MADISON,WI 53706.

This elevation was independent of changes in PTH, ionized calcium, or phosphate. This paper investigates the potential sources and mechanisms for this increase in both rats and mice. Kidney homogenates from rats treated for 14 days with (15 mg/kg) had a significant increase in 25-hydroxyvitamin D (25OHD)-24-hydroxylase (24-hydroxylase) activity (149 +/- 20 vs. 89 +/- 16 fmol/mg.min; P < 0.05), but nonsignificant increases in 25OHD-1-alpha-hydroxylase (1-alpha-hydroxylase) activity compared to controls. Kidney homogenates from C57b16J mice after the administration of 30-50 mg/kg CsA for 3 days revealed a linear dose-related increase in renal 1-alpha-hydroxylase (r = 0.96; P < 0.05), which became significant with doses of 30 mg/kg CsA or more (P < 0.05). To investigate the source of this 1,25-(OH)2D production, serum 1,25-(OH)2D was measured before and 48 h after bilateral nephrectomy in rats receiving CsA for 16 days. The percent decrease in serum 1,25-(OH)2D values was not significantly different in CsA-treated and untreated rats (33.9 +/- 4.9% vs. 47.5 +/- 4.9%), indicating little or no contribution from nonrenal sources. Studies of MCRs and production rates (PRs) revealed that the elevated 1,25-(OH)2D values were due to enhanced production and not altered clearance (PR, 12.4 +/- 1.2 vs. 19.1 +/- 1.9 fmol/mg.min; P < 0.01). CsA increases 1-alpha-hydroxylase activity and produces significant elevations in serum 1,25-(OH)2D levels in both rats and mice. This increase may have an impact on bone mineral metabolism and immune modulation in postorgan transplanation patients.

Most have led directly to or have been driven by an author's philosophy of earth-forming processes. However, the practical need of classifying land for planning and management purposes requires that a system lead to predictions of the results of management activities. We propose a landscape classification system composed of 11 units, from realm (a continental mass) to feature (a splash impression). The classification concerns physical aspects rather than economic or social factors; and aims to merge land inventory with dynamic processes. Landscape units are organized using a hierachical system so that information may be assembled and communicated at different levels of scale and abstraction. Our classification uses a geomorphic systems approach that emphasizes the geologic-geomorpohic attributes of the units. Realm, major division, province, and section are formulated by subdividing large units into smaller ones. For the larger units we have followed Fenneman's delineations, which are well established in the North American literature. Areas and districts are aggregated into regions and regions into sections. Units smaller than areas have, in practice, been subdivided into zones and smaller units if required. We developed the theoretical framework embodied in this classification from practical applications aimed at land use planning and land management in Maryland (eastern Piedmont Province near Baltimore) and Utah (eastern Uinta Mountains).

This caused significant increases in annual flow volumes and annual instantaneous peak flows. North Fork remained untouched, but both streams were in disequilibrium before harvest time. Due to wetter years during the postharvest period, North Fork also experienced some flow increases, but the difference was not significant. Flow increases cause increased erosion in disequilibrium channels. While in South Fork channel cross sections enlarged by 10% since preharvest time, those in North Fork enlarged by only 2.5%. The number of knickpoints tripled in South Fork, which was about double that in North Fork. Knickpoint development resulted in destruction of the natural control structures (log steps and transverse gravel bars) in South Fork (47%), while in North Fork they increased by 23%. Knickpoints are scarps on the channel bed that have the appearance of gully headcuts. The tripling of the number of knickpoints signifies that adjustment processes of the bed profile are intensified drastically in South Fork. The geomorphic changes signify that due to increases in discharge, the extent of disequilibrium is exacerbated in South Fork. Yet, volumes of erosion are relatively small, as will be sediment volumes leaving the watershed at a given time, because of the stepwise sediment transport occurring in this ephemeral stream.

In one phase of DDRP, land use, wetland, and forest cover data were collected for statistical samples of 145 Northeast lake and 35 Southern Blue Ridge Province stream watersheds in the United States. Land-use and other data then were extrapolated from individual to target watershed populations. Project statistical design allows summarization of results for various subsets of the target population. This article discusses results and implications of the land-use and land-cover characterization for both regions. Forest cover was the primary land use in both regions. In the Northeast, developed (agriculture and urban) land was positively associated with surface-water chemistry values for acid neutralizing capacity, Ca plus Mg, pH, and sulfate in the Pocono/Catskill subregion. Extensive wetlands and beaver activity occur in parts of the Northeast region, whereas topography limits wetland and riparian development in the Southern Blue Ridge Province. Northeast soils have low sulfate adsorption capacity, most watersheds are near sulfur steady state, and lake sulfate concentrations are controlled principally by levels of sulfur deposition. Net annual sulfur retention in Northeast watersheds in positively correlated with ocurrence of wetlands and beaver impoundments. In contrast, most Southern Blue Ridge Province soils have high sulfate adsorption capacities, resulting in high net watershed sulfur retention. At the present time, stream sulfate concentrations and percent sulfur retention are controlled principally by soil chemical properties related to adsorption rather than atmospheric deposition and land use.

The Chi-square test for goodness of fit was used to analyze segregating populations. Two independent recessive genes appeared to control resistance of Reichenbachii to both TLM and MBCT. Depending upon the cross, the two genes interacted cumulatively to condition immunity or higher levels of resistance than either parent conditioned singly. There was no evidence of maternal influence on the inheritance of resistance. Resistance genes in Reichenbachii were recessive; therefore, breeders should consider the use of relatively large F2 populations to effectively transfer these genes to cultivars with good agronomic characteristics.

This study was undertaken to investigate genetic factors controlling reduced plant height and increased stem diameter in three sources of sunflower, DDR, Donsky, and Donskoi 47, crossed with a conventional height line, HA 89. As these two characters may lead to improved standability, knowledge of their inheritance will assist researchers in utilizing proper breeding methods. Estimates of additive, dominance, and epistatic genetic effects controlling reduced height indicated that the additive component was most important in two of the three crosses with the additive and epistatic component nearly equal in the third cross. Breeding efforts to reduce height of sunflower hybrids utilizing these lines in crosses could be effective due to the magnitude of additive effects. The dominance component of genetic effects controlling stem diameter was the most important for two crosses, with both dominance and additive components important for the third cross. Epistasis was present, but minor, for controlling stem diameter. The high relative importance of the dominance component indicates that testcross evaluation of lines in early generations could identify lines for producing increased stem diameter in hybrids. Even though the three sources of sunflower with reduced height were different in morphologic and agronomic characteristics, they had similar genetic control of plant height and stem diameter. Each could be utilized in a breeding program to develop lines with reduced height and larger stem diameter. C1 N DAKOTA STATE UNIV,DEPT CROP & WEED SCI,FARGO,ND 58105.

This method, referred to as cross-blot, uses only 120-mu-l of antigen or antibody and can be completed in less than 6 h. Cross-blot was developed for rapid screening of hybridoma culture supernatants and can be adapted for use with Western blots of native and denatured proteins as well as screening polyclonal antibodies. In this study, murine monoclonal antibodies were produced to Postia placenta, a brown-rot wood decay fungus. Immunizing antigens were derived from P. placenta-decayed wood extracts. The antibodies were screened for specificity to a number of native proteins produced by the fungus. Cross-blot proved to an efficient method of visualizing cross-reacting antibodies while screening large numbers of antibodies for specificity.

Past research has indicated that crops grown under conservation production systems are subjected to cooler and wetter soil conditions than crops grown with conventional tillage practices. Information is needed to determine if a significant interaction exists between tillage and hybrid in maize. Field experiments were conducted in 1982 and 1983 near Lincoln, Nebraska, U.S.A., on an Abruptic Argiaquoll and in 1983 near Gothenburg, Nebraska, U.S.A., on a Typic Haplustoll under dryland and irrigated conditions, respectively, to evaluate the response of eight hybrids to several tillage practices. Tillage practices studied were moldboard plow, tandem disk, and no-tillage. Tillage practice had a significant effect on only plant emergence at Lincoln during 1983 and dry matter production at Lincoln in 1982 and Gothenburg in 1983. Hybrids differed in plant population at harvest, rate of phenological development, leaf area and dry matter production, and grain yield. A significant tillage x hybrid interaction was observed for dry-matter production at the tasseling stage at Lincoln during 1983; however, no significant interactions were observed for grain-yield among the hybrids and tillage systems investigated. Results indicate that for the adapted hybrids tested, relative grain-yield comparisons will be maintained with both conservation and conventional tillage practices.

Recent findings show that a third tropic level can be involved as well. Herbivore-injured plants release relatively large amounts of volatiles that are attractive to natural enemies of the herbivores. The host-searching behavior of the generalist parasitoid Cotesia marginiventris is mediated by such plant produced volatiles. Since plant and entomophage both profit from this interaction it has been suggested that the plant responses serve to recruit the entomophages. Here we argue that induced production of plant chemicals evolved first as a direct defense against herbivores, and that the attractive function likely evolved secondarily. Results of a plant palatability experiment are given to provide preliminary support for a defensive function. Plants that were induced to release volatiles that are known to be attractive to the parasitoid became less palatable to the herbivore beet armyworm.

Densities of most tussock-moth populations fluctuate over time with considerable regularity. Fluctuations in density on warm, dry sites where populations have a high intrinsic rate of increase are more likely to periodically reach outbreak numbers than where rates of increase are relatively small. Such cycles of abundance are inherent properties of the tussock-moth system that are not likely to change in susceptible host types. Modern pest-management programs emphasize the annual monitoring of insects in forests with outbreak histories to determine early changes in population numbers and to predict trends. When outbreaks develop, several environmentally safe chemical and microbial insecticides are effective in reducing larval numbers and preventing serious defoliation. Computer models predicting growth loss, tree mortality, and top-kill during outbreaks are available as aids to making management decisions. Silvicultural practices favoring seral nonhost species on high-risk sites may be the best prescription for reducing the impact of tussock moth outbreaks.

Here we address this issue by considering variations in host suitability for the budworm due to tree species, age, nutrient levels, defensive compounds, inducible defenses, and stress. Tree age has minor effects on foliar nutritional quality. Nitrogen levels (as an index of protein) in the diet appear to be the most significant factor affecting performance both in the field and laboratory. Tannins/phenolics, and supraoptimal levels of calcium in host foliage may interfere with the bioavailability of some minerals such as iron. Monoterpenes can be toxic at very high levels but otherwise seem to have minor negative effects on budworm performance. There is little evidence of short-term inducible defenses in fir foliage. Likewise, there is little evidence that drought stress makes fir trees more nutritionally favorable for spruce budworm. However, drought-induced flowering may be very important to larval survival. Neither is there evidence for substantial variation among trees in their inherent susceptibility to budworm. We hypothesize that variations in host-plant quality are less important in regulating budworm dynamics than other factors, such as the physical environment and natural enemies. However, spruce-budworm/host-plant phenological synchrony and host flowering status may be very important variables that deserve more research. Management of budworm will require more detailed knowledge about the entire complex of community factors that contribute to the increased likelihood of outbreak development.

Budworm performance was generally negatively associated with food moisture content, rather than positively associated as reported by others. Furthermore, increased moisture in the artificial diets did not improve the efficiency with which the budworm could utilize the nitrogen in the diets. Budworm survival, pupal biomass, and development time were best on diets with low N and low water or high N and low water. Water appeared simply to be acting as a diluent in these experiments. For the western spruce budworm the importance of plant water and N as key nutrients for predicting herbivore performance may not be direct cause-and-effect but, rather, to be related to other factors that are linked to these characteristics in plant tissues. Water is not likely to be a critically limiting nutrient when budworm larvae feed on the new, current-year needles of their conifer hosts. The higher moisture levels tested, 84% and 88%, did not improve larval performance; thus, the budworm's enhanced growth on early-season, new foliage may not be directly associated with the higher moisture content of new, expanding needles, but is probably related to other factors linked to plant water content.

Government policymakers, supported by forest pest management scientists and practitioners, directed that IPM be used to protect forests from the effects of insects and disease. Unfortunately, transferring the concept of IPM from agriculture to forestry has been more difficult than expected.

This represents roughly 23% of the total land area of the Earth, and equals almost one ha per head of population. To accommodate a projected world population of 6.4 million persons by the year 2000-with its accompanying demands for food and fiber, effects on the land and its productivity, and on the environment-will present an exciting, difficult, and continuing challenge to resource managers. Research, academic, and resource management professionals face the particularly different challenge of analyzing and anticipating long-term research, technology, and educational needs to design programs to train professionals and to develop and effectively implement technology capable of meeting these changing resource and pest-management demands. Our future goals and actions in management, protection, and use of the Earth's natural resources must be approached with consideration of global conditions. As communication and transportation networks place us in closer contact with our global neighbors, it becomes increasingly clear that our resource management decisions, today and in the future, will not only affect our own future generations, but also those of our neighbors around the world.

When the site preparation savings resulting from the energy-wood harvest were included in the analysis, however, a different break-even point was determined.

The manufacturing of raw materials into semifinished and finished products provides high employment for the wood sector labor force. High value added during manufacturing of products for export overcomes the high cost of importing wood raw materials, benefiting the national economy. In some subsectors of the industry, such as furniture, Italy is recognized as a world leader, and in other allied sectors, such as the production of woodworking machines, Italy also has a strong world position. Timber production in Italy should gradually increase in the future, although due to a number of factors (geomorphology of the territory, environmental and climatic conditions, characteristics of the estate system, legal restrictions, etc.), it will probably never be completely self-sufficient. The problems related to the present utilization of the local wood resources (low work productivity, very high costs) can be reduced by 1) a gradual introduction of specialized mechanization that is appropriate to the local working conditions; 2) better organization of labor for the whole forestry utilization sector, starting with the professional hiring and training of the workers; and 3) changes in the national policy for management of forest resources.

Root sprouting was heaviest on north and east (downhill) sides of residual trees; bole sprouts were concentrated on the south and west (uphill). Root and bole sprouting appeared to be responding to different stimuli, or responding differently to the same kind of stimulus. Thinning affected sprout growth, but not sprout numbers. Sprouting responses were at the tree level rather than the thinning treatment level. Unexpected sprouting occurred in uncut control plots. Light, temperature, or mechanical activity may have affected sprouting on trees in the thinned plots.

Principal components regression has the advantage of avoiding model specification error due to variable deletion. The technique works as follows: the independent variables are orthogonalized into their principal components; components with low information content are deleted; the model is estimated by ordinary least squares; then the principal component estimators are converted into coefficients in the original parameter space, where a judgement about their contribution is made via an F-test. An example using tree growth data is presented to demonstrate the merits of principal components regression over variable deletion. Results indicate that "correct" structural specification does not have to be compromised through variable deletion when collinearity is present. This obviously has implications for large-scaled regression models, in which an increased number of independent variables in the specification may promote a level of collinearity that is not conducive to making statistical inferences. Analytical methods like principal components, that adjust for the effects of collinearity on the variable selection process, are merited.

Both equations are modifications of the Chapman-Richard's growth curve which has parameters for the asymptote and the annual rate of growth towards the asymptote. The original form is modified by defining the asymptote and annual growth rate as functions of changing stand conditions. For basal area projection the asymptote is a function of number of trees which approaches zero as density declines. The rate of approach to the asymptote is a function of growth in average dominant and codominant trees and change in average stand age. The survival equation is a reverse Chapman-Richard's curve that approaches zero over time. The asymptotic value is a decreasing function of basal area in accordance with the self-thinning rule. Additional terms controlling the rate of movement away from the asymptote are a minimum mortality rate for low density stands and ingrowth of new trees into the smallest diameter class for young stands with vigorous basal area growth. Nonlinear three-stage least squares procedures are used to simultaneously fit both equations to a natural longleaf pine (Pinus palustris Mill.) permanent plot data set. Predictions are verified using cross-validation procedures, and long-range extrapolations are demonstrated and discussed.

This paper examines that objective, and the success the Forest Service can have in attaining it, through its intended maintenance of a constant volume timber harvest schedule. We apply a three-factor, two-sector modified general equilibrium model with empirical evidence from the timber-based counties of western Montana. Departure from a market responsive timber policy can have positive impacts on the wood products sector, but the net effects on the local community are very small. The costs to the public treasury of pursuing such a policy dwarf these small community benefits. C1 US FOREST SERV,SE FOREST EXPT STN,RES TRIANGLE PK,NC 27709. US ECON RES SERV,WASHINGTON,DC 20250.

Knowledge of the limit to sustainable foliar biomass at a given level of photosynthetically active radiation and under minimum environmental stress would have important implications for modeling primary forest productivity. Theoretical analysis and limited experimental data collected on even-aged plant populations that are undergoing self-thinning indicate that total stand foliar biomass should achieve a nearly constant value for a given species and site. Average diameter-plant density relations for various conifers species coupled with available foliage mass-stem diameter equations were used to approximate the maximum amount of foliage which could be sustained. Source of bias and effects due to changes in specific leaf area are evaluated. The maximum foliage biomass calculated in this manner was subject to positive bias, but estimates at low densities correspond to values obtained empirically for mature stands growing under very favorable environmental conditions. Calculated estimates suggest that maximum sustainable foliage biomass increases slightly with decreasing plant density along the self-thinning line, in contrast to expectations. The magnitude of the increase depends upon the relative value of the self-thinning exponent compared to the exponent of the allometric equation. Changes in light distribution in relation to crown architecture, particularly crown depth and foliage clustering, may account for this effect. C1 AUBURN UNIV,AGR EXPT STN,AUBURN,AL 36849.

The paper begins by reviewing the classic approach to this class of problems, "chance-constrained programming," followed by a discussion of "joint probability chance-constrained programming," and a new alternative "total probability chance-constrained programming." The paper then develops three "chance-maximizing" counterparts. Specific formulations for executing these approaches in natural resource management problems are developed that explicitly include the cumulative probability density functions. A forestry case example demonstrates solution procedures and shows that the different approches can yield substantially different results. Results from different solution procedures are also compared. C1 MICHIGAN TECHNOL UNIV,SCH FORESTRY & WOOD PROD,HOUGHTON,MI 49931.

Family differences in height were statistically significant throughout most of the period, while differences in breast-high diameter were detected after year 13. Estimated heritabilities for height were relatively constant, averaging 0.11 and 0.33 for individuals and families, respectively; those for diameter have generally increased throughout the period and by year 25 had reached 0.14 for individuals and 0.43 for families. These heritabilities coupled with relatively large phenotypic variances suggest that programs of forward selection should provide genetic gains of about 7% in the height or 9% in the diameter of individual trees in year 25. Genetic correlations of height at various ages with stem volume in year 25 were high (> 0.85), as were the correlations involving diameter and 25-yr volume after year 13. Correlated responses to selection suggested that year 7 would be the most efficient time to select, providing 85% of the maximum gain available in 25-yr volume. A stand simulation model was used to project the yields (volume per acre) expected from the progenies of selections made in year 7. Results of the simulations suggested that the amount of increase in yield depended on the density, rotation length, and manner by which genetic gains accrue beyond year 25. The results implied that relatively small gains in the attributes of 25-yr-old trees can result in either increased volumes per acre for a given rotation or decreases in the rotation to achieve a given volume.

Promoter deletion analysis in transgenic plants demonstrated that only minimal (< 200 bp) promoter proximal regions are required for developmentally regulated expression in pollen and in specific cell types of the sporophyte. Cis-acting regulatory regions of these two promoters and of a third pollen-expressed promoter (LAT56) were characterized in detail using a transient expression assay. We identified two upstream activator regions in the LAT52 promoter and further showed that a 19-bp segment from one of those regions enhanced expression of the heterologous CaMV35S promoter in pollen. Similarities in sequence between crucial cis elements provide evidence that shared regulatory elements are involved in the coordinate expression of the LAT genes during microsporogenesis.

However, for various pedologic and geomorphic reasons, soil development at crest sites may not truly reflect the time since moraine formation; for example, some crest soils on moraines of greatly different age are similar in morphology and development. Soil catena data for soils at several sites aligned downslope from the crest can greatly improve on the usefulness of soil data for estimating moraine ages. For this purpose we use the weighted mean catena profile development index, which condenses field data for all of the soils in each catena into a single value.

At 70, 90 and 110 days of gestation, three fetal pigs were obtained from each of three obese and lean dams. The heart, kidneys, lungs, liver and one biceps femoris muscle were removed, weighed, frozen and extracts prepared. For all the organ and tissue weights, there were significant (P < .001) main effects of genotype (G) and fetal age (A). At each fetal age, pre-obese fetuses had lighter organ and tissue weights. The content of IGF's in serum and various tissues and/or organs was also determined. Main effects of A and G were significant (P < .05) for liver and lung IGF-I and muscle IGF-II concentrations. Main effects of G were significant (P < .01) for liver IGF-II whereas muscle IGF-I and lung IGF-II concentrations were only affected by fetal age (P < .01). Overall, liver IGF-I and II and muscle IGF-II concentrations were higher in lean fetuses (P < .01). Serum IGF-I concentration increased (P < .01) with fetal age and was independent of fetal strain. Serum IGF-II concentration increased with age (P < .01) in lean but not pre-obese fetuses. Therefore, these studies demonstrate genotype dependent growth factor concentrations in tissues and organs of developing fetuses. Finally, serum concentration of IGF's were strongly correlated (positive) with overall growth but were not strongly correlated with tissue and organ concentration of IGFs.

Mammary, liver, and adipose explants from somatotrophin and control cows were co-cultured at 37-degrees-C for 24 h with 0.5-mu-Ci [C-14]acetate/ml media with or without 0.5-mu-g/ml somatotrophin. Tissue lipids were extracted with chloroform/methanol and separated by thin layer chromatography. In vivo somatotrophin increased milk production 2.4 kg/day compared to a 0.9 kg/day decrease by controls. Mammary tissue from somatotrophin cows incorporated more [C-14]acetate into total lipids (4417 vs. 3016 dpm/mg tissue) than controls. Adding somatotrophin to explant cultures from somatotrophin cows further increased incorporation into total lipids (4839 vs. 3994 dpm/mg tissue). In contrast, adipose tissue from somatotrophin cows incorporated less [C-14]acetate into total lipids than controls (1524 vs. 2581 dpm/mg tissue). Serum IGF-I concentration correlated well (r = 0.69) with milk output differences between Days 1 and 5 of treatment. Media IGF-I concentration correlated well (r = 0.61) with the difference in total lipid synthesis between the in vitro control and somatotrophin groups. Results support the concept that somatotrophin increases milk production by partitioning nutrients away from adipose toward mammary tissue.

Five of these antigens reacted on immunoblots from 7 to 14 days after inoculation with oocysts. A parasite antigen of approximately 11,000 molecular weight demonstrated intense reactivity on immunoblots from 7 to 23 days after inoculation. The 11,000-molecular-weight antigen also reacted on immunoblots with parenterally raised antioocyst and antisporozoite rabbit sera. These results indicate that cell-mediated as well as humoral immune responses are initiated by cryptosporidial infection in calves and that the 11,000-molecular-weight parasite antigen is immunodominant.

Indirect immunofluorescence and colloidal gold immunoelectron microscopy revealed that the antibody reacted with both the sporozoite and merozoite surface plasma membranes. On Western immunoblots, MAb5C3 binding was found to be strongly inhibited when 200 mM N-acetylglucosamine was used as a competing sugar. N-acetylglucosamine was used as a competing sugar. N-Acetylgalactosamine inhibited binding of the antibody only slightly, whereas glucose, mannose, and galactose failed to inhibit binding. MAb5C3 was found to recognize a similar 15-kDa epitope associated with a Cryptosporidium sp. isolated from guinea pigs. However, MAb5C3 failed to react with any proteins or glycoproteins associated with C. baileyi from chickens, Cryptosporidium sp. (= bovine C. muris) from cattle, C. serpentis from a rat snake, bradyzoites of Besnoitia darlingi from an opossum, sporozoite/oocyst extracts of Caryospora bigenetica from an eastern diamondback rattlesnake, sporozoites of Eimeria nieschulzi and E. papillata from rats and mice, or tachyzoites of Toxoplasma gondii (RH strain). When hybridoma supernatants containing MAb5C3 were administered orally to suckling mice experimentally infected with C. parvum, a 75% reduction in developmental stages was seen histologically at 72 h postinfection and a 67.5% reduction in mean oocyst output was found at 6 days postinfection.

Removal of the leptospiral outer membrane by using 0.1% Triton X-114 was demonstrated by whole-mount electron microscopy and by essentially complete solubilization of a lipopolysaccharidelike substance (LLS) from the outer membrane. Triton X-114 (0.1%) did not solubilize subsurface proteins, such as endoflagellar filaments or penicillin-binding proteins, which are markers for the periplasmic space and inner membrane, respectively. Triton X-114 solubilized material from both the virulent and attenuated strains, which partitioned into the hydrophobic, detergent phase, contained LLS and major proteins of 41 and 44 kDa, which were also immunoprecipitable from intact organisms. The virulent strain contained greater amounts of an LLS component with an apparent molecular mass of 30 kDa (R(f) = 0.57), whereas the attenuated strain contained larger amounts of an LLS component with an apparent molecular mass of 20 kDa (R(f) = 0.74). Differences in protein components between virulent and attenuated organisms were also detected; whereas the 41- and 44-kDa proteins were immunoprecipitated in equal amounts from both the virulent and attenuated strains, a 33-kDa protein was immunoprecipitated in significantly greater amounts from the attenuated strain. Quantitation of outer membrane particle density by freeze-fracture electron microscopy showed that both strains had a low transmembrane outer membrane protein content compared with that of typical gram-negative bacteria. The virulent and attenuated strains had 443 and 990 particles (P < 0.000001) per mu-m2, respectively, in the concave outer membrane fracture face. These findings suggest that in vitro cultivation of L. interrogans is accompanied by quantitative and qualitative changes in both LLS and outer membrane-associated proteins.

After a 14-16 hour fast, rats were killed. Liver and kidney enzyme activities were determined in the LA/N-cp rats while plasma urea and selected amino acids were determined in all rats. Liver glucose-6-phosphatase (G6PASE), fructose-1,6-bisphosphatase (FBPASE), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphate dehydrogenase (G6PDH), 6-phosphogluconate dehydrogenase (6PGDH), malic enzyme (ME), glucokinase (GK), pyruvate kinase (PK), phosphofructokinase (PFK), glutamic-oxaloacetic-transaminase (GOT), glutamic-pyruvic transaminase (GPT), arginase (ARGASE), arginine-synthase (ARG-SYN) and ornithine transcarbamylase (OTC) levels were significantly affected by phenotype (obese > lean). All the above changes in enzyme levels were exaggerated by sucrose-feeding with the exception of PK, PFK, GOT, GPT, ARGASE and ARG-SYN. Kidney cortex G6PASE, PEPCK and ARGASE activities were higher in the obese rats as compared to the lean littermates. Sucrose feeding resulted in higher cortex G6PASE, FBPASE and PEPCK as compared to starch-fed rats. A phenotype effect was noted with plasma glutamate, urea, leucine, isoleucine and valine (obese > lean) and a diet effect was seen with aspartate, phenylalanine, leucine and valine (sucrose > starch) concentration. Sprague-Dawley rats had higher plasma urea and lower alanine than lean LA/N-cp males. Metabolic obesity in the LA/N-cp rat appears to involve an elevated capacity for pathways of glycolysis, gluconeogenesis, lipogenesis and amino acid catabolism in the liver.

The present study investigated the genotoxic potential of seeds from four nongrain sources: jimson weed (Datura stramonium), velvetleaf (Abutilon theophrasti), sicklepod (Cassia obtusifolia), and morning glory (Ipomoea spp.). Mutagenic responses of methanolic extracts of these seeds were determined by using four bacterial strains (TA98, TA100, TA102, and TA2637) with and without microsomal activation. Relative potencies were compared by using the following parameters derived from dose-response curves: (a) mutagenic potency or revertants per milligram equivalent seeds (R/MES), which is defined as the maximal mutagenic response produced by 1 mg of seeds, and (b) mutagenic potential, which relates minimal effective dose (MED) with the estimated number of seeds required to produce a significant mutagenic response. Although the seed extracts elicited responses in all four bacterial strains, TA102 was the most sensitive. The following numbers of toxic weed seeds per 15 g of grain are estimated to constitute a minimal effective dose with TA102 and microsomal activation: morning glory, 1; sicklepod, 6; velvetleaf, 50; jimson weed, 566. These results show that morning glory and sicklepod seeds contain high levels of mutagens. Possible sources of mutagens and possible reasons for the observed variation of relative mutagenic potency are discussed. These observations provide a rational basis for relating seed composition to genotoxic effects and for assessing the possible safety of low levels of weed seeds in the diets of food-producing animals and in human diets.

Comparison of the Minolta Chroma Meter II CR-100 and Model 96 Spectrogard color systems indicates that the CR-100 system can be used for the measurements needed. However, it only gives CIELAB color values directly. A simple equation, Hunter L = CIELAB L* -7, can be used to convert L* values to L values in the L* range 52-65. By use of four data sets from a 3-year period, an optimum L* value was found to which peanuts should be roasted to obtain optimum roasted peanut attribute response. Across these data sets optimum L* varied from 58.2 to 59.5, suggesting that samples should be roasted to L* values of 58-59 or L values of 51-52 when optimum roasted peanut attribute is of primary interest. Analysis of the data has shown that adjusting for overroast and/or underroast attributes when present reduces the correlation to zero between the roasted peanut attribute and roast color.

The method includes a limited acid hydrolysis of the samples in 6 N DCl, thus avoiding the complete racemization of LAL residues, and the measurement of unlabeled and LAL isomer distributions. A range of heated or alkali-treated proteins of plant or animal origin were analyzed. All samples contained LL- and LD-LAL in similar amounts with, however, a significant stereoselectivity in favor of LD-LAL in samples subjected to moderate processing conditions (low temperature, short time, or low alkaline pH). A minimum relative concentration of ca. 40% was found for LL-LAL in the least-treated proteins. Computer modeling indicated a possible difference in the heats of formation between LL- and LD-LAL isomers which could explain the observed asymmetric distributions. The presence of both LAL isomers in similar proportions in all proteins indicates that the postulated two-step mechanism for LAL formation applies for both cyst(e)ine and serine-phosphate as precursors.

Leaves and squares were collected for analysis of allelochemicals (gossypol, tannin, anthocyanin, flavonoids) at 3 and 5 weeks after the first treatment. The plots were machine harvested one time to determine yield. Seeds were delinted and analyzed for agronomic traits and gossypol. Leaf gossypol and square gossypol were the categories most frequently increased by the bioregulators. Kinetin, and kinetin plus CaCl2 or Na2SeO3, and mepiquat chloride (PIX) alone or with a commercial cytokinin preparation (Foliar Triggrr) all increased gossypol and one or more of the other allelochemicals significantly. A sugar-amino acid fraction isolated from Foliar Triggrr increased cotton yield by 26% when applied as a foliar dressing at 2.88 mol/ha, as well as increasing gossypol. These results suggest that plants under stress may respond positively to nutrient foliar applications, giving both increased allelochemicals and improved yield.

Factors were temperature (10, 25, and 40 degrees-C), illumination (light or dark), and time (from 0 to about 4100 min in 820-min increments). Triclopyr BEE penetration into chinkapin leaves is greater than into madrone leaves at all temperatures. Foliar penetration into madrone leaves did not increase between 25 and 40-degrees-C. Losses in the dark were greatest from glass slides and least from chinkapin. Triclopyr BEE loss from chinkapin leaves at 40-degrees-C in the light was equivalent to loss in the dark at 40-degrees-C. Losses of triclopyr BEE from both glass slides and madrone leaves were greater in the light treatments. Models were developed by using mass balance coefficients.

These studies have been limited, however, in using food expenditure equations that are linear in the coefficients, placing prior constraints on the estimated marginal propensities to spend (MPS) from cash and from stamps. This article re-examines the earlier MPS estimates in light of a more general and flexible food expenditure equation, comparing estimates from a common data set under alternative functional forms. The article estimates changes in food spending that would result under each functional form from "cashing out" food stamps, and replacing stamps with equivalent cash benefits. Results show that: MPS estimates vary widely depending on functional form; past estimates tended to substantially exaggerate the cashout effect in reducing food spending; and the most general, consistent, and flexible forms show a 10-cent reduction in food spending for each dollar of food-stamp benefit shifted to a cash payment.

Model results show that declines in the acreage reduction program (ARP) would reduce agricultural fertilizer use, but the return of ARP land to production would lead to an overall increase in sedimentation and offsite environmental damage. In contrast, if land and fertilizers are highly substitutable, declines in deficiency payments and other commodity price support programs would reduce offsite environmental damages by reducing fertilizer use. Agricultural policy reform would be consistent with conservation policy because it would encourage a reduction in the use of fertilizer-intensive production practices.

A normalized restricted profit function is used to estimate profit and factor demand functions from farm-level, cross-sectional data for the food grain and jute crops in Bangladesh. The estimated elasticities are used to evaluate price support and fertilizer subsidy programs in terms of their costs to the government, foreign exchange effects, and producer surplus for the food grain and jute sectors.

Daily milk yield as measured by the lamb suckling weight differential technique did not differ (P > .05) among breeds, although milk production of Suffolk ewes tended to be higher than that of the other three breeds. Within the Rambouillet, Columbia, and Polypay breeds, total estimated yield of ewes with twins was 13 to 17% higher than that of ewes with singles, whereas in the Suffolk breed, suckling twins increased total milk yield 61% over that of ewes with singles. Twin lambs induced a larger differential in dam milk production in late lactation (70 to 98 d) than in earlier lactation (28 to 70 d). Number of lambs did not influence milk protein, Ca, or P content (P < .05). Fat levels in colostrum and 4-d milk were elevated 14 and 20%, respectively, in ewes suckling twins compared with ewes suckling singles. Under range conditions, Suffolk ewes suckling single or twin lambs lost more BW (12 and 21% of 4-d postpartum body weight, respectively) than Rambouillet (4 and 7%), Columbia (5 and 8%), or Polypay (8 and 8%) ewes. Correlation coefficients of milk production and lamb growth rate were positive and significant (P < .05) up to 56 d of age. Growth rate was less closely associated with milk production for twin than for single lambs. C1 USDA,ARS,US SHEEP EXPT STN,DUBOIS,ID 83423.

Breed effects were evaluated for the nine parental breeds (Red Poll, Hereford, Angus, Limousin, Braunvieh, Pinzgauer, Gelbvieh, Simmental, and Charolais) that contributed to the three composite populations. Breed effects were significant for all traits evaluated except survival at birth. The large differences among breeds in additive direct and additive maternal genetic effects offer a great opportunity to use the genetic differences among breeds to achieve and maintain optimum additive genetic (breed) composition to match genetic resources to a wide range of production-marketing ecosystems. There was no heterosis for gestation length. Mean heterosis for dystocia was significant estimated in F1 but not in F2 or in the combined F3 and F4 generations. Mean heterosis was not significant in any generation for survival at birth, to 72 h, and to weaning for the F1 generation; mean heterosis was significant for survival to weaning for the F2 generation and approached significance (P = .06) for the combined F3 and F4 generations. Mean heterosis over all composite populations and heterosis for each composite population were significant in all generations for weight at birth and at 200 d and for ADG from birth to weaning. Retained heterosis was not less than expected from retained heterozygosity in composite populations for the traits evaluated. These results suggest that heterosis for these traits likely is due to dominance effects and, thus, can be attributed to the recovery of accumulated inbreeding depression in the parental breeds.

Calves resulting from embryo transfers (ET) were weaned early (3 to 5 d). Reciprocal cross mating also were made by natural service (NS) between BS and H and between RP and A breeds; part of the offspring were weaned at 3 to 5 d, and the remainder nursed their dams to an age of 150 to 180 d. This was done to estimate breed differences in prenatal and postnatal effects combined and to separate the effects of prenatal maternal influences from postnatal maternal influences of these breeds. Females produced in both ET and NS parts of the experiment were retained to produce three calf crops to an age of about 4.5 yr. The following traits were analyzed: percentage of conception rate; percentage of calf survival; percentage of calves produced per cow exposed; birth and weaning weights of calves produced; and periodic weights, heights, and condition scores of females to an age of 4.5 yr. Neither breed of donor (cytoplasmic influence) nor breed of recipient (uterine influence) had consistently important effects on the traits evaluated. In NS matings, differences between reciprocal crosses were small for most of the traits evaluated. Method of rearing (nursed vs weaned at 3 to 5 d) had no effect on reproductive and maternal traits for RP-A reciprocal cross females, but females that nursed generally were heavier, were taller, and had higher condition scores at most ages than early-weaned females. For the BS-H reciprocal cross, early-weaned females were favored over females reared by their dams in percentage of calves produced per cow exposed, but the method of rearing did not affect other reproductive or maternal traits. BS-H reciprocal cross females that nursed their dams were heavier at 550 d and were heavier and had higher condition scores at an age of 34 mo than early-weaned females.

Subsequent generations were produced by inter se mating. The objective was to compare Composite sheep to purebred Suffolks for numerous performance traits. Young ewes lambing at 1 yr of age were evaluated separately from mature ewes (2, 3, 4, and 5 yr old) of each population. Composite and Suffolk populations did not differ significantly in components of litter weaning weight per young ewe joined. Mature Composite ewes produced more wool than Suffolk ewes. Fertility of mature ewes did not differ significantly between populations. The greater prolificacy (P < .01) of mature Suffolk ewes was offset by a lower survival to weaning (P < .01), particularly for twin-born lambs. Consequently, mature Composite and Suffolk ewes did not differ for number weaned and litter weaning weight per ewe joined. The average birth weight of lambs born to young and mature Composite ewes was greater (P < .02) than the average birth weight of Suffolk lambs. The average weaning weight of lambs born to young Composite ewes was greater (P < .05) than that of lambs born to young Suffolk ewes. Breed differences were not detected for preweaning daily gains, weaning weights, and postweaning daily gains of ewe lambs born to mature ewes. Likewise, weights of ewes at 125 d of age and weights of mature ewes at breeding did not differ significantly between breeds. Overall productivity of Composite ewes was at least equal to that of Suffolk ewes, and weights from weaning to maturity of Composite and Suffolk ewes were similar.

Carcass data were obtained for 401 of these bulls at 16 mo of age and on 101 that were sires or alternates and slaughtered at 30 mo of age. Fifty-five bulls slaughtered at 30 mo of age sired 301 male offspring on which growth data were obtained and 30 sired 169 male offspring on which carcass data were obtained. Bulls gained an average of .75 kg/d preweaning and 1.16 kg/d postweaning on a 168-d feed test. Rate of daily gain from the end of feed test to slaughter ranged from .7 to 1.2 kg/d. Time from the end of the feed test to slaughter ranged from 48 to 140 d. Slaughter weight, marbling score (Small = 12, Traces = 6), longissimus muscle area, fat covering over the 12th rib, percentage of kidney, pelvic and heart fat (KPH), and dressing percentage for bulls slaughtered as yearlings were 470 kg, 7.6 score, 82.5 cm, 8.2 mm, 1.0%, and 58.8%, respectively. The 30-mo-old bulls were slaughtered directly from range pastures. Marbling was devoid or practically devoid and fat covering over the 12th rib and KPH fat were insufficient to measure or estimate accurately. Sufficient variation was not available for statistically analyses of these traits. Slaughter weight, longissimus muscle area, and dressing percentage of 30-mo-old bulls were 583 kg, 91.8 cm, and 54.0%, respectively. Son-sire pair regression and covariance methods were used to estimate heritabilities and genetic correlations for growth and for carcass traits other than fat-related traits. Heritabilities estimated were .21 for birth weight, .21 for preweaning gain, .24 for weaning weight, .50 for gain on test, .47 for 365-d weight, .49 for slaughter weight, .33 for carcass weight, .32 for dressing percentage, and .01 for longissimus muscle. Genetic correlations among most growth characteristics approached 1.00, which would indicate that selection to increase any growth characteristic will increase other growth characteristics. Heritabilities found in this nonselected population were in agreement with heritabilities of growth traits reported in the literature from selected populations.

This 2-yr study examined the diet and diet characteristics of steers grazing tall fescue (Festuca arundinacea Schreb.), switchgrass (Panicum virgatum L.), flaccidgrass (Pennisetum flaccidum Griseb.), and bermudagrass (Cynodon dactylon [L.] Pers.) pastures. A randomized complete block design was used with two agronomic replicates. In vitro DM disappearance (IVDMD) of masticates from tall fescue (TF), switchgrass (SG), and flaccidgrass (FG) generally were similar; all exceeded 70% (70.3 to 79.9%), except for bermudagrass (BG), which was lowest (63.5 to 65.0%). Sieving the masticate DM showed BG to contain the highest proportion (20 to 29%) of particles passing a .5-mm sieve and the lowest proportion (6 to 8%) of particles retained on a 2.8-mm sieve. This resulted in BG having the smallest mean (1.29 mm) and median (1.08 mm) particle sizes in yr 1 and a mean (1.10 mm) and median (.91 mm) particle size smaller than SG in yr 2. Except for BG, the IVDMD of the masticate DM was lowest for small particles. Canopies showed BG and SG to have the highest proportion of stem (47 and 52%, respectively); the BG canopy was composed of fractions that were consistently lowest in IVDMD. In general, BG offered the grazing animal a canopy inferior in IVDMD concentration and had canopy characteristics that limited the animals' selectionof a diet with quality as high as that of TF, SG, or FG.

This 2-yr study examined DMI, gastrointestinal tract fill of undigested DM (FILL), rate of digesta passage (ROP), and digesta mean retention time (MRT) for steers grazing tall fescue (Festuca arundinacea Schreb.), switchgrass (Panicum virgatum L.), flaccidgrass (Pennisetum flaccidum Griseb.), and bermudagrass (Cynodon dactylon [L.] Pers.). A randomized complete block design was used with two agronomic replicates. Comparisons in June (yr 1) among continuously grazed switchgrass (SG), flaccidgrass (FG), and bermudagrass (BG) or in May (yr 2) among tall fescue (TF), SG, and FG showed similar digesta kinetics, but different DMI (kg.d-1.100 kg BW-1), among these forages within each sampling. In the June evaluation, the DMI of SG and FG were similar (xBAR = 3.09), DMI of bermudagrass (BG) was lowest (2.23), and fecal DM output (FO) was similar among forages. In the May evaluation, DMI by steers grazing SG (3.90) was higher than that by steers grazing FG (2.97); DMI of tall fescue (TF) was intermediate (3.41) but similar to DMI of FG. Differences in DMI were due to differences in diet in vitro DM disappearance (IVDMD) rather than to differences in digesta kinetics. In July (yr 2), the MRT was highest for BG (84 h) and similar for SG and FG (57 h). Steers grazing different forages exhibited similar ROP and FILL, but FO (kg.d-1.100 kg BW-1) among steers varied (.37 for steers fed BG; .74 for steers fed SG and FG). The DMI predicted for BG was only 41% (1.06) of the mean for SG and FG (2.57). At this sampling, the low DMI for BG was associated both with reduced FO and with low diet IVDMD. Mean ADG of steers on a pasture reflected DMI estimates (r = .83). C1 N CAROLINA STATE UNIV,DEPT CROP SCI & ANIM SCI,RALEIGH,NC 27695. N CAROLINA STATE UNIV,DEPT ANIM SCI,RALEIGH,NC 27695.

We found correspondence between the lower limit of this forest - the ecotone where red fir yields dominance to white fir (Abies concolor) - and changes in snowpack. Analysis of atmospheric soundings revealed that the mean freezing level during storms from December to March (the period of maximum precipitation) centres on the ecotone. There is a strong discontinuity with elevation in the form of winter precipitation (snow versus rain) that geographically coincides with the red fir-white fir ecotone. The proportion of red fir at fifty-one stations in northern California was more strongly correlated with long-term mean 1 April snow water equivalence (SWE) than with elevation. Four elevational transects at different latitudes through the white firred fir ecotone also showed positive, significant correlations between red fir importance and both snow depth and SWE.

Two of the monoclonal antibodies, designated CB6 and IB4, exhibited reactivity toward only cells containing lipid in stromal-vascular cell cultures. The antigens recognized by the CB6 and IB4 monoclonal antibodies were 50 kD and 55 kD proteins, respectively. In vivo, IB4 immunoreactivity was detected only in lipid-containing cells, whereas immunofluorescence using CB6 was also detectable around muscle fiber bundles underlying the subcutaneous mesenchyme. In fetal subcutaneous mesenchyme, CB6 and IB4 immunoreactivities toward lipid-containing cells increased with developmental age, but each was not detectable in cells containing the smallest lipid droplets. In stromal-vascular cultures containing adipocytes, 48 hour treatment with the anti-lipogenic agent, growth hormone, only slightly altered CB6 immunoreactivity whereas IB5 immunoreactivity was reduced by more than sixfold. The exact identity of the CB6 and IB4 antigens was not determined, but each may be useful as markers for studying regulation of adipocyte metabolism.

One of the principal predators of Ips pini is Thanasimus dubius (F.), which uses ipsdienol as a kairomone for prey location. During 1988 and 1989, in Wisconsin and Michigan, the response of both species to a range of enantiomeric blends of ipsdienol was investigated. Blends tested had the following ratios of the (S)-(+) to (R)-(-) enantiomers: 3%:97%, 25%:75%, 50%:50%, 75%:25%, and 97%:3%. Either 75% (+):25% (-) or 50% (+):50% (-) ipsdienol captured the most Ips pini in both years at both sites. The 25% (+):75% (-) blend also caught more Ips pini than the control during both years at both sites. All blends tested were attractive to Thanasimus dubius in both years at both locations. Blend preferences of both species were variable and labile at both sites. Response patterns of both species in Wisconsin were different from those in Michigan each year. Furthermore, response patterns of both species to the ipsdienol blends changed from 1988 to 1989 at both locations. A genetic component to this variation would permit predator-prey coevolution, as well as the development of resistance by Ips pini to management strategies based on mass-trapping with single blends.

Earlier work established that a 12-carbon lactone, (Z)-oxacyclotridec-10-en-2-one, was responsible for the feeding deterrent properties of the steam distillate from M. rugosa. The concentration of this volatile varied with plant age and leaf position. The maximum concentration in leaves of M. rugosa (area basis) was estimated, on the basis of tests using an inert substrate, to be too low to cause a detectable inhibition of feeding. No correlation between lactone content and weevil feeding was detected when leaves from similar positions on plants of different ages were used in a multiple choice bioassay. Although small amounts (< 12.5-mu-g) of (Z)-oxacyclotridec-10-en-2-one can inhibit adult alfalfa weevil feeding on 13-mm-diameter membrane filters, because leaf concentrations (area basis) of this compound are lower than required to cause a detectable inhibition of feeding on the inert substrate, and becuase concentrations do correlate with weevil feeding, it is unlikely that this lactone is responsible for resistance to adult alfalfa weevil feeding exhibited by M. rugosa.

Previous studies have shown that packed-column SFC-FID of polar solutes is difficult due to the unshielded surface silanols on SFC stationary phases. The use of a polymeric resin-based stationary phase or high-temperature water saturation with a bonded-silica column eliminates the problem. With the use of the polymeric resin-packed column, silanophilic interactions are non-existent. High-temperature water saturation of the carbon dioxide mobile phase provides water as a modifier at levels of 2 to 3 mole%, levels previously unattained in packed-column SFC. At this concentration, water notably minimizes fatty acid interactions with the bonded-silica column, yet allows the use of FID. These two chromatographic approaches are illustrated on lipid-containing samples such as oil from storage-abused soybeans and a commercial frying fat. Chromatograms obtained by packed-column SFC-FID are compared with separations attained using capillary-column SFC. Packed-microbore SFC-FID results show a linear correlation with free fatty acid content determined by a standard titration method. C1 USDA ARS,NO REG RES CTR,1815 N UNIV ST,PEORIA,IL 61604.

Litter sizes were adjusted at birth to 0 (postpartum nonlactating group), 4, 8, 12, and 16 pups per lactating rat. Serum and tissue samples were collected from lactating rats and pups on d 12 of lactation and from 6 nulliparous females. Nulliparous and postpartum nonlactating rats did not differ in serum thyroxine, triiodothyronine concentrations, or in 5'-deiodinase activity in liver and kidney. As litter size increased, maternal serum thyroxine, triiodothyronine concentrations, and 5'-deiodinase activity in liver and kidney decreased. Growth rate of pups was inversely correlated with litter size and positively correlated with concentration of serum thyroxine and liver 5'-deiodinase in mothers. In pups, serum triiodothyronine concentrations decreased as litter size increased, but serum thyroxine concentrations were not affected. Results suggest a relationship between the hypothyroid status of lactating rats and suckling intensity. The thyroid status of the dam may influence thyroid status and growth of offspring.

Grinds included 1) undried with dry ice in a Vita-Mix 3600 Plus blender, 2) undried in a Hobart chopper, 3) undried in a Wiley grinder, 4) in a Wiley grinder (20 mesh) after oven drying 60-degrees-C, and 5) intact. Presentation methods included 1) rectangular cell, 15-cm path, with and without polyethylene bags, and 2) a nonrotating circular cell. Undried (including dry ice regrinds of Hobart-grind and Wiley-grind) and dried silages were analyzed for DM, CP, and ADF. Each calibration was performed three times (average used) with each third of the samples used once as the validation set. Results, for undried samples, for DM and CP were about the same for all methods of grinding, presentation, and source of chemistry. Overall, the undried Wiley ground samples in the rectangular cell gave better results than any other grind-cell combination among the Wiley, Hobart, and intact undried materials. Intact samples generally did not result in satisfactory estimates of composition, even when multiple samples were scanned and averaged, nor did wavelengths below 1100 nm.

Two field replicates each of first-cutting alfalfa (bud and midbloom) and orchardgrass (prehead and head) were treated at harvest with 0 (no solution applied), 2, 4, 6, or 8 g NaOH/100 g forage DM. Forages were hand cut, hand sprayed, and sun cured as hay. Disappearance kinetics of cell wall monosaccharides were measured by suspending polyester bags containing the forages in the cow's rumen for 6, 12, 24, 36, 60, and 72 h. Alkali treatment resulted in the following effects on forage NDF: decreased galactose content in mature orchardgrass and decreased glucose content of immature alfalfa; increased disappearance of xylose and glucose in all forages except in mature alfalfa; and increased rate of disappearance of xylose in immature orchardgrass and mature alfalfa and of arabinose in immature orchardgrass. Alkali treatment had limited effects on content of cell wall monosaccharides of two maturities of orchardgrass and alfalfa. Excluding mature alfalfa, alkali treatment increased disappearance of cell wall xylose and glucose in all forages. C1 PENN STATE UNIV,DEPT DAIRY & ANIM SCI,UNIVERSITY PK,PA 16802.

(2) Net throughfall fluxes (throughfall minus precipitation transfers) showed consistent canopy effects on rainfall chemistry, with SO42-, PO43-, Cl-, K+, Ca2+ and Mg2+ added to rainfall by foliage, whereas NO3--N, NH4+-N and H+ ions were absorbed from precipitation. Storm characteristics (event amount and duration) accounted for the largest portion of the variability in growing season net throughfall fluxes, suggesting that canopy exchange was the major mechanism of throughfall transfer. (3) Stemflow fluxes increased canopy exchange rates of SO4(2-), PO4(3-), Cl-, K+, and Mg2+ by greater than 20% in a regression model of total below-canopy element fluxes. (4) Cation leaching fluxes were highly variable (C.V. > 50%) over spatial scales of several m2, but could be explained largely by heterogeneity in canopy cover. (5) Foliar cation leaching losses in the early successional forest accounted for 4-13% of leaf nutrient reserves. As cation throughfall transfers were highest during storms with the greatest hydrogen ion uptake from rainwater, it is hypothesized that acid precipitation is causing accelerated foliar nutrient leaching in south-eastern hardwood forests.

Consequently, a major control point of public health significance - husbandry and the farm environment - is often overlooked. This paper defines the livestock and poultry husbandry principles on which the control of Salmonella at the production level should be based. The Salmonella cycle is so complex that developing a system for breaking it presents a formidable long-term challenge to the public health community. But the critical importance of the farm in perpetuating the disease process demands near-term improvement of husbandry and environmental practices. Preventive action in the production phase of the cycle is feasible through cooperative efforts.

This paper reports the full-scale wall and corner test results of step 2 of this study. A room fire test following the ASTM proposed standard specifications was used for these full-scale tests. In step 1, we investigated the combination of factors for evaluating wood products in wall and corner fire tests. They were the position of the ignition source, power output from the source, and combination of lining materials. We concluded from the sensitivity study (step 1) that for wall and corner fire tests, a burner output program consisting of 40 kW exposure for 5 min followed by 160 kW exposure for 5 min was the most informative. In this paper, step 2 of the research program, results from wall and corner tests using six wood materials having different flame spread indices (according to ASTM E 84) are given. The two-step burner setting was confirmed to be better than a constant setting for evaluating wood materials. The relative performance of these materials was in line with their ASTM E 84 flame spread properties. Smoke release rates obtained by white-light and laser systems showed excellent agreement. Only rate of heat and smoke release, selected temperatures, and heat fluxes are reported. The complete reduced data set will be published later. C1 NATL FOREST PROD ASSOC,WASHINGTON,DC 20036.

The temperature of 52-degrees-C had low lethality for cells grown at 37 or 42-degrees-C, but there was a 10(3)-10(4)-fold increase in killing for cells grown at 28, 19, 10, or 5-degrees-C. There was little injury with exposure to 52-degrees-C of cells grown at 5, 10, or 19-degrees-C, but injury increased as the temperature of growth increased. When cells were grown anaerobically, lethality induced at 52-degrees-C increased as the growth temperature decreased, but there was more injury under anaerobic conditions than for aerobically grown cells. The results indicate that L. monocytogenes cells growing at low temperatures are more susceptible to heat induced death.

Apple tissue absorbed more AAP and AA than potato under similar conditions. AAP hydrolysis by endogenous acid phosphatase (APase) yielded AA which accumulated or became oxidized to dehydroascorbic acid, depending on the rate of hydrolysis and browning tendencies of samples. APase activity varied greatly with commodity, method of sample preparation and sample pH. Variation in the ability of AAP to inhibit browning in different products could be explained by these factors.

The concept of niche width refers to a species' distribution according to environmental conditions, reflecting environmental tolerances. Drunella doddsi was found over a broad range of elevations, and average minimum stream flows. However, its distribution was highly correlated to streams with moderate to high gradients, coarse substrates, dense riparian vegetation, low to moderate levels of alkalinity, very low levels of sulfates, and low specific conductance. This narrow niche width seems to indicate an intolerance of D. doddsi to many types of environmental conditions. Specific habitat selection also requires competitive prevalence over other species that would utilize that habitat. C1 BRIGHAM YOUNG UNIV,DIV MATH SCI & TECHNOL,LAIE,HI 96762.

Immunogold labelling and electron microscopy of embedded and sectioned wheat and maize cells doubly infected by different potyviruses revealed no mixing of inclusion proteins in CIs. The viruses were wheat streak mosaic virus (WSMV), agropyron mosaic virus and hordeum mosaic virus, in wheat, and WSMV and maize dwarf mosaic virus in maize. The three viruses in wheat were indistinguishable morphologically and in ultrastructural features but can be separated by serology and host range. The absence of phenotypic mixing in CIs showed that in the presence of CI proteins of other potyviruses, assembly was either highly virus-specific, or that no opportunity existed for CI proteins to assembly into hybrid CIs in mixed infections.

The MAb binding match between members of the same virus pair ranged from 10/10 to 7/10. The genomic relationship was evaluated by studying the hybridization characteristics of two cDNA probes and six complementary 20 base oligomer probes with virus DNA, selected on the basis of conservation between published BVD virus sequences; cDNA probes were hybridized at two stringencies (60-degrees-C and 45-degrees-C). The match of hybridization results between members of the same virus pair ranged from 4/4 to 1/4 with the cDNA probes and from 6/6 to 3/6 with the oligomer probes.

Cosegregating F2 families were identified by meiotic examination and, among these, single plants expressing both mutations (double mutants) were cytologically analyzed. Expression of both mutant phenotypes within one plant indicated the two corresponding genes were independently expressed; the wild-type activity of one gene was not required for initiation or activity of the other. Observations from 12 double mutants indicate that an all-encompassing regulatory cascade at the level of the gene does not exist in meiosis. Instead, results suggest the independent control of genes involved in pairing, spindle formation, cytokinesis, and other meiotic events. Events that occur at the conclusion of meiosis were not found to depend on successful execution of events earlier in the cycle. Reduction division appears to be a merging of individual independent activities. C1 UNIV MISSOURI,DEPT AGRON,COLUMBIA,MO 65211. UNIV MISSOURI,USDA ARS,COLUMBIA,MO 65211.

Soil parameters derived from data in standard USDA soil surveys are used, and 99 rainfall events are modeled. The runoff distributions obtained from the model are then used with a hydrograph model to predict the peak discharge from the watershed. Procedures are applied that adjusted the Green-Ampt infiltration parameters for various cover and condition classes. The model is applied to areas of up to 54 sq mi with a wide variety of soil and cover conditions. The runoff volumes and peak discharges are compared with the measured values and with those predicted by the Soil Conservation Service (SCS) curve-number procedure. The Green-Ampt model predicted both the runoff volume and peak discharge better than the curve-number model. The standard error of estimate was less for the Green-Ampt model in nine of 12 watersheds for runoff volumes and in 11 of 12 watersheds for peak discharges.

In this phase of the study rescaling geometrically proportional (self-affine) surface and bedrock slope profiles provide an analytical framework for defining the shape, volume and dynamic changes of saturated flow for this hillslope system. Rescaling self-affine hillslope trajectories along a stream reach, collapses the flow-domain to a unit cube. A dynamic model for hillslope runoff is proposed, and implications for modeling topographic controls on the snowmelt process are suggested. C1 USDA ARS,NW WATERSHED RES CTR,BOISE,ID 83705.

A new compound, 7,10-dihydroxy-8-(E)-octadecenoic acid (DOD) was produced from oleic acid by a new strain, Pseudomonas sp. PR3 isolated from a water sample in Morton, IL. Strain PR3 is a motile, small rod-shaped, Gram-negative bacterium. It has multiple polar flagellae and is oxidase-positive. Strain PR3 grows aerobically and cannot grow anaerobically. The strain produces white, smooth colonies on agar plate and no water-soluble pigment. The yield of the product was greater than 60%. The optimum time, pH and temperature for the production of DOD were: 2 days, 7.0, and 30-degrees-C, respectively. Glycerol and dextrose support the growth of strain PR3, but the cells grown from the former failed to catalyse the conversion of oleic acid to DOD. The production of DOD is unique in that it involves a hydroxylation at two positions and a rearrangement of the double bond of the substrate molecule. C1 USDA ARS,NO REG RES CTR,PEORIA,IL 61604.

SO JOURNAL OF INORGANIC BIOCHEMISTRY LA English DT Article ID DIVALENT-CATION INTERACTIONS; PHYTIC ACID; ION INTERACTIONS; IRON AVAILABILITY; COMPLEX-FORMATION; ZINC-PHYTATE; RATS; BINDING; BIOAVAILABILITY; PRECIPITATION AB The complexation of Fe(III) and Cr(III) with inositol hexaphosphate (phytic acid) has been studied by calorimetry. The reactions were examined at metal ion: phytate mol ratios 1 and 4, in the instance of Fe(III), and 4 only in the case of Cr(III). The heats of reactions were endothermic within these mol ratios. Precipitation occurred in each instance of the Fe(III)-phytate reactions. From measurements of the remaining Fe(III) and phytic acid concentrations, it was calculated that 4.1 mol Fe(III) bind per mol precipitated phytate at initial mol ratio 4:1. In a similar manner it was found at the initial, lower mol ratio of 1:1 that 3.5 Fe(III) bind per mol precipitated phytate. The heats of precipitations (which include binding, solvation changes, etc.) of the Fe(III)-phytate reactions were approximately 16 kcal mol-1. This value is substantially smaller than those obtained for most previously investigated metal ion-phytate precipitation reactions. Possible reasons for the lower heat of precipitation of the Fe(III)-phytate reaction are discussed. The Cr(III)-phytate reactions were investigated under conditions in which both soluble and insoluble complexes formed. Certain complications, which are detailed, existed in these studies. An unusually large value, i.e., 81 kcal mol-1, was obtained for the heat of precipitation of the insoluble Cr(III)-phytate complex. Due to the above mentioned complications, this enthalpy of precipitation, together with the experimentally determined value of 11.5 mol Cr(III) per mol phytic acid precipitated, are subject to considerable uncertainty. On the basis of the present, and previously reported results (reference 12), it is proposed that Al(III) has a greater affinity for phytic acid than does Fe(III), which in turn exhibits a greater affinity than does Cr(III).

Parasitism by Muscidifurax raptor and Nasonia vitripennis was greatest in dry substrates, with the latter preferring bright illumination and the former tending to prefer dark. Urolepis rufipes selected bright illumination and moist substrates, attacking the most hosts at bright-moist and dim-moist microhabitats. Spalangia cameroni exhibited no main-effect preference for light intensity or moisture, although parasitism was highest at dim-moist, dark-wet, and dark-moist microhabitats. These results demonstrate that simple abiotic attributes, such as light intensity and substrate moisture concentration, are important in defining some dimensions of the niches of these parasitoids.

This paper analyzes an alternative iterative procedure for quickly and accurately solving the implicit problem of determining the normal flow depth in complex channel sections. Conditions that guarantee a unique solution and guarantee that the iterative procedure will converge to the solution are developed. A computer program for quickly and accurately finding the unique solution, using the Chezy or Manning flow resistance equations, is available. Test runs for a rectangular, a triangular, a trapezoidal, and two complex channel cross sections are used to evaluate the effectiveness of the procedure. The test results show that the iterative procedure presented here meets the requirements of guaranteed convergence, computational efficiency (speed and accuracy), and the ability to handle both trapezoidal and complex channel cross sections.

The association of two apoE5 isoforms with elevated plasma low density lipoprotein cholesterol levels in two unrelated subjects led us to investigate the primary structures and receptor-binding properties of their apoE. Cysteamine modification and isoelectric focusing demonstrated that the apoE5 isoform from subject 1 did not contain cysteine but that the apoE5 isoform from subject 2 contained one residue of cysteine. The structural mutation in the apoE5 isoform of subject 1 was determined by peptide sequencing. Like apoE4, this variant had arginine at position 112 but differed from apoE4 by the substitution of arginine for proline at position 84. When purified and subjected to a competitive binding assay, this apoE5(84 Pro --> Arg, 112 Cys --> Arg) variant had the same receptor-binding activity as normal apoE3. Because subject 2 was of Japanese descent and her apoE5 contained one cysteine residue, we suspected that it would contain the lysine-for-glutamic acid mutation at position 3 that has been described previously in Japanese subjects. This was confirmed by directly sequencing the first 10 amino acid residues of her apoE. When subjected to the competitive binding assay, the total apoE from subject 2, which consisted of approximately equal amounts of normal apoE3 and apoE5(3 Glu --> Lys), had a binding activity of 188%, confirming the previously reported enhanced binding of this variant. These results demonstrate that the enhancement of receptor-binding activity of more basic isoforms of apoE depends on the position at which additional positively charged amino acids are incorporated.

The new subgenus and species differ from one or both of the single species in each of the other two subgenera, Thalassornectes and Rallidectes, by (1) the normal size, position, and parallel arrangement of the genital papillae; (2) the larger size of seta sce; (3) the greater length and stronger development of setae sci, d1, l1, h, and sh; (4) the equal size of tarsi III and IV or their size subequal, with tarsus IV slightly longer than tarsus III; (5) both epimera I and sternum well developed and nearly equal in length; and (6) the free sclerotized posteriad extension from epimerite II on the ventral cuticular surface. This is the first hypoderatid reported from the host order Charadriiformes. The distribution of T. (Alcidectes) aukletae among auklets may be attributed to either cospeciation or may have an ecological basis; data are insufficient at present to sustain either hypothesis.

The model is deterministic and based on a dynamic life table with weekly time steps. The model simulates the effects of major environmental variables, such as ambient temperature, saturation deficit, precipitation, type of pasture, type of cattle, and cattle density on Boophilus cattle tick population dynamics. General validity of the model is established by comparing simulated and observed yearly densities of standard female ticks/host/day. B. microplus population comparisons were made for a series of years using weekly weather data from two locations in Queensland, Australia. The model also produced acceptable values for initial population growth rate, generation time, and 3-yr population density when historical weather at 7 locations in Australia and 23 locations in the Americas were used. This model provides a framework for the study of Babesia transmission by Boophilus ticks, and can be used to study the effects of control technologies and to develop more efficient and environmentally acceptable eradication strategies for Boophilus ticks.

Significantly greater numbers of all taxa were collected as the level of CO2 was increased.

Because the mixture of proteins in human milk is particularly rich in tryptophan and cysteine and low in methionine, this pattern is difficult to achieve with commercially available proteins. Even whey-predominant formulas only approximate human milk. Human milk has a high concentration of whey protein (70% of total protein). Of this, alpha-lactalbumin, a component of the lactase synthetase complex, accounts for 41% of the whey and 28% of the total protein. Only 3% of the protein in bovine milk is alpha-lactalbumin. Human and bovine alpha-lactalbumin share a 72% amino acid sequence homology. Both proteins contain (wt/wt) 6% tryptophan and 5% cysteine but only 0.9% methionine. Thus the differences in the amino acid compositions of bovine and human milks are largely attributable to differences in their alpha-lactalbumin contents. Commercial availability of bovine alpha-lactalbumin would allow the construction of infant formulas with amino acid compositions that are very close to that of human milk. alpha-Lactalbumin would also be a valuable constituent of diets for patients whose protein intake must be restricted.

Fischer 344, male rats, aged 15 weeks, and 6, 15, and 25.5 months at the end of the 12-week study, were divided into diet groups of ad libitum controls, deficient or pair-fed controls. Plasma PLP levels in 25.5-month-old control rats were lower (P less-than-or-equal-to 0.05) than the other three age groups which were slightly, but not significantly different from each other. Plasma PLP of deficient rats was dramatically decreased (P less-than-or-equal-to 0.05) in all age groups. Muscle PLP was decreased (P less-than-or-equal-to 0.05) in all vitamin B-6 deficient rats. Liver and brain PLP concentrations were decreased (P less-than-or-equal-to 0.05) in 15 week, 6 month, and 15 month deficient rats only. Tissue PLP levels were correlated (P less-than-or-equal-to 0.01) with plasma PLP. Vitamin B-6 deficiency resulted in decreased glycogen phosphorylase activity (P less-than-or-equal-to 0.05) in muscle, liver, and brain of 15 week rats, and in muscle and liver of 6 month rats. Reduction in food intake did not account for the reported changes during vitamin B-6 deficiency. A significant correlation between tissue glycogen phosphorylase activity and tissue PLP levels was observed. Vitamin B-6 deficiency significantly lowered tissue PLP and phosphorylase activity, but the decrease in each was less marked with increasing age.

Paclobutrazol reduced the height, fresh weight, and ABA levels of wheat seedlings. The magnitude of the inhibitory effect of paclobutrazol on ABA levels was dependent on the length of time after application. ABA levels in plants as determined by gas chromatography-selected ion monitoring-mass spectrometry (GC-SIM-MS) were reduced by 50-60% 2 days after soil application. A further 15% reduction occurred by the seventh day after treatment. ABA level analyses began at the time of treatment with 4-day-old seedlings and continued until 21 days after treatment when only a 20% reduction was detected. These determinations using GC-SIM-MS should increase the understanding of triazole effects on ABA levels.

This temperature conditioning treatment reduced the severity of chilling injury in the squash during subsequent storage at 2.5-degrees-C. The ABA levels remained higher in treated squash than in untreated samples throughout the storage. Direct treatments of squash with ABA at 0.5 and 1.0 mM before storage at 2.5-degrees-C increased ABA levels in the tissue and were also effective in reducing chilling injury.

The analytical vehicle used in the analysis consists of a computable general equilibrium model composed of 12 producing sectors, 13 consuming sectors, 6 house-hold categories classified by income, a foreign sector, and a government. We find first that, irrespective of the type of strategy directed at improving environmental quality that is followed, both output and consumption decline, as does household utility. Hence, there is a quantifiable trade-off between economic activity (economic growth) and the quality of the environment. Beyond this, the aggregate loss in production and economic welfare (measured by consumption expenditures and utility) is less under a policy that stresses reliance on alternative fuels (brought about by taxation) than through one that requires the installation of pollution abatement devices (i.e., regulation).

This behaviour is significant because it relates to the performance and durability of paper in changing environments, but adequate test methods have been lacking. In the new test method described here, sorbed moisture is continuously measured as tensile stress is applied to the specimen. The report cites data that verify the method and compares experimental results with those predicted by the theory of Barkas.
