La habilidad de T orizicolus de transmitir el virus es una característica controlada genéticamente. Debido a que en la naturale­za existen muchos factores que influencian el porcentaje de insectos vectores de T orizicolus, este estudio se realizó para deter­minar el porcentaje de insectos que tienen la capacidad genética de transmitir el RHBV. Se colectaron muestras de T orizicolus en varias regiones arroceras de Colombia, en campos que presentaban diferentes niveles de infesta­ción de RHBV. El porcentaje de insectos con capacidad genética de transmitir el RHBV fue siempre mayor que el porcentaje de insectos que fue­ron vectores virulíferos en el campo. Este método es útil como un indicador y ha sido utilizado para identificar las regiones arroceras de Colombia que están en gran ries­go de presentar epidemias de RHBV.

AU - Sato, Suguru T2 - HortScience AB - Peet et al. (1997) demonstrated that in male-sterile tomato plants ( Lycopersicon esculentum L. Mill cv. NC8288) (MSs) provided with pollen from male-fertile plants (MFs) grown at 24°C daily mean, percent fruit set, total number and weight of fruit, and relative seediness decreased linearly as mean daily temperature rose from 25 to 29°C. The primary parameter affecting these variables was mean temperature, with day temperature at a given night temperature, night temperature at a given day temperature, and day/night temperature differential having secondary or no effect. To compare the effect of temperature stress experienced only by the female tissues with that experienced by the male tissues or both male and female tissues, MSs and MFs were grown in 28/22°C, 30/24°C, and 32/26°C day/night temperature chambers. Fruit yield and seed number per fruit declined sharply when increased temperatures were experienced by both male and female tissues (MFs). There was no fruit set in any of the MSs assigned to the 32/26°C pollen treatment, mostly because of the limited amount of pollen available from MFs. Both fruit production and seed content per fruit were also greatly reduced in MSs receiving pollen from 30/24°C grown MFs for the same reason. For plants experiencing stress only on female tissues (MSs grown at high temperatures, but receiving pollen from MFs grown at the lowest temperature), there was also a linear decrease in fruit yield as growth temperatures increased, as previously seen by Peet et al. (1997), but the temperature effect was less pronounced than that on pollen production. Thus, for this system, temperature stress decreased yield much more drastically when experienced by male reproductive tissues than when experienced only by female reproductive tissues.

AU - Foster, Rick E. AU - Buhler, Wayne T2 - Environmental Entomology AB - Seedcorn maggot, Delia platura (Meigen), is an important pest of early-planted melons. Two field experiments were conducted over a 3-yr period to discern (1) the time intervals between incorporation of a rye, Secale cereale L., cover crop and the percentage of muskmelon, Cucumis melo , var. Superstar, transplants killed by seedcorn maggot and (2) the soil temperature that seedcorn maggot injury was not detectable. The 1st objective was accomplished by incorporating a rye cover crop into the soil 2, 1, and 0 wk before muskmelon transplants were set in the field. The 2nd objective was accomplished by transplanting muskmelon seedlings at 4 weekly intervals in 1994 and 1995 and 11 intervals (2–4 d) in 1996. Incorporation intervals did not influence seedcorn maggot injury. In 1994, no plants were killed with any incorporation time, whereas in 1995, ≈60% of plants in each of the 3 incorporation intervals were killed by seedcorn maggot. Soil temperature proved to be a better indicator of damage potential, as demonstrated in the 2nd trial. When soil temperatures were below 18°C, 30–60% of transplants were killed. However, when soil temperatures were above 21°C, <3% of plants were killed. Soil temperature under black plastic mulch appears to be the most important factor in determining if seedcorn maggots will damage early season muskmelon transplants.

F 1 plants showed bitter kernel. Segregation in the F 2 fit a 3 bitter : 1 sweet phenotypic ratio, suggesting that sweet kernel is controlled by a single recessive gene, for which the symbol sk is proposed. Sweet kernel ( sk ) was linked to nectarine ( g ) at a map distance of 12 cM. Seed bitterness phenotype is controlled by the genotype of the maternal tree and not the genotype of the individual embryo. Inheritance of male sterility derived from plant introduction (PI) 240928 and allelism of male sterile genes found in `Chinese Cling' and `White Glory' were investigated. Analysis of F 1 , F 1 open-pollinated, and BC 1 families derived from crossing PI 240928 with six different wild-type cultivars showed that male sterility in PI 240928 is controlled by cytoplasmic factors. Allelism studies showed that the male-sterile gene found in `White Glory' is not allelic to ps found in `Chinese Cling', and hence is designated ps2.

They were fried and their flavor and texture evaluated by sensory panels. Selected physical and compositional analyses were performed on raw and fried SP. An untrained preference panel tended to score the flavor of the sweeter types highest and the texture of the firm types higher than sweet types. A trained profile panel identified and scored flavor notes and texture categories. This research indicated that the intensity of the flavor notes sweetness and starch and the intensity of texture notes first-bite moistness and first-bite hardness were highly correlated with some of the compositional parameters. Correlation between compositional parameters and the flavor and texture note intensities listed above could be developed into a system to predict those sensory properties in newly developed selections without having to resort to sensory analyses.

In order to eliminate known effects of high temperatures on pollen production and stylar position, high temperature treatments were applied only to male-sterile tomatoes (Lycopersicon esculentum Mill.). Pollen was obtained from male-fertile plants given optimal growth conditions. This allowed comparison of mean daily temperatures from 25–29 °C; day/night temperature differentials (DIFs) of 2, 6, and 10°C; day temperatures of 28, 30 and 32°C at night temperatures of 22, 24, and 26°C; and night temperatures of 22, 24 and 26°C at day temperatures of 28, 30 and 32°C. Average weight per fruit and flower number did not demonstrate a consistent pattern of response to high temperature. Other reproductive characteristics (% fruitset, total number and weight of fruit per plant, and seediness index) decreased as mean daily temperature rose from 25°C to 26°C and from 28°C to 29°C. The primary parameter affecting these variables was mean daily temperature, with day temperature having a secondary role. Thus, in determining reproductive responses of tomato to temperatures within this range, day temperature, night temperature and DIFs do not need to be considered independently of their effect on mean daily temperature. If this relationship holds true in other species, and for pre-pollen production pro- cesses as well, modelling the effects of projected climate change should be simplified.

Most of the plants tested gave negative reactions in all NCM‐ELISA, only c. 5% giving positive reactions to SPFMV and c 1% to SPMMV or SPCFV. Graft inoculations of cuttings from symptomless sweet potato plants, obtained either at Namulonge Agricultural and Animal Production Research Institute (NAARI) or from farmers' fields, onto seedlings of the near‐universal indicator plant for sweet potato viruses, Zpomoea setosa, caused symptoms in c. 15% of indicator plants; in all such cases, SPFMV alone was identified by NCM‐ELISA. Supplementary tests, involving further grafting of sweet potato to I. setosa seedlings or grafting sweet potato plants themselves with sweet potato sunken vein virus (SPSVV), which in the presence of SPFMV causes sweet potato virus disease (SPVD), confirmed the absence of infection in sweet potato cuttings which had not caused symptoms on I. setosa in the initial graft test. Possible mechanisms explaining the prevalence of virus‐free sweet potato plants in farmers' fields are discussed.

Senescence and limited lifespan are thought to arise because weak natural selection late in life allows the accumulation of mutations with deleterious late-age effects that are either neutral (the mutation accumulation hypothesis) or beneficial (the antagonistic pleiotropy hypothesis) early in life. Analyses of Drosophila spontaneous mutations, patterns of segregating variation and covariation, and lines selected for late-age fertility have implicated both classes of mutation in the evolution of aging, but neither their relative contributions nor the properties of individual loci that cause aging in nature are known. To begin to dissect the multiple genetic causes of quantitative variation in lifespan, we have conducted a genome-wide screen for quantitative trait loci (QTLs) affecting lifespan that segregate among a panel of recombinant inbred lines using a dense molecular marker map. Five autosomal QTLs were mapped by composite interval mapping and by sequential multiple marker analysis. The QTLs had large sex-specific effects on lifespan and age-specific effects on survivorship and mortality and mapped to the same regions as candidate genes with fertility, cellular aging, stress resistance and male-specific effects. Late age-of-onset QTL effects are consistent with the mutation accumulation hypothesis for the evolution of senescence, and sex-specific QTL effects suggest a novel mechanism for maintaining genetic variation for lifespan.

RAPD analysis of these accessions showed a corresponding division into the same two groups determined by PGM analysis, except for two accessions with unique RAPD phenotypes. Field-grown accessions showed distinguishing morphological characters corresponding to the groupings from the isozyme and RAPD analyses. Those in the predominant isozyme and RAPD groups, as well as the two with unique RAPD phenotypes, exhibited smooth lateral stems, while those in both nonpredominant groups exhibited markedly bristly laterals. These results suggest that the 24 accessions are ramets of two major clones with one clone predominating and that, contrary to long-standing belief, the Cherokee rose has not naturalized by reseeding in the southeast. PGM and RAPD analyses of putative Cherokee rose hybrids `Anemone' and `Silver Moon' showed that `Anemone' is likely to be such a hybrid but that `Silver Moon' is not. Historical records revealed that widespread vegetative propagation of the Cherokee rose was initiated in 1820-21 and that L. Wiesener, not J.C. Schmidt, was the originator of `Anemone'.

In one field test, which did not include NYL 235-4, the incidence of corn-borer damaged stems was eight times higher in the commercial potato varieties Atlantic, Superior and Norland than in K411-2. In a later field test, there were 11 times more European corn-borer damaged potato stems on Atlantic than on NYL 235-4. In a choice experiment, European corn-borer moths deposited significantly more egg masses on the susceptible Kennebec variety (72.9%) than on NYL 235-4 (27.1%), but in the absence of a choice, equal numbers of egg masses were deposited on both varieties. In a greenhouse experiment, fewer European corn-borer larvae (44%) were established on NYL 235-4 than on Kennebec plants.

The general formulas are based on two matrices D and Q, where D is the genetic design matrix, characterizing the genetic effects of the QTLs, and Q is the conditional probability matrix of QTL genotypes given flanking marker genotypes, containing the information on QTL positions. With the general formulas, it is relatively easy to extend QTL mapping analysis to using multiple marker intervals simultaneously for mapping multiple QTLs, for analyzing QTL epistasis, and for estimating the heritability of quantitative traits. Simulations were performed to evaluate the performance of the estimates of the asymptotic variances of QTL positions and effects.

Schmidt. Variations in foliar heat tolerance among these species were manifested in temperature responses for A CO2 . Temperature optima of A CO2 for I. rugosa, I. cornuta , and I. aquifolium were 22.0, 26.3, and 27.9 °C, respectively (LSD 0.05 = 2.9). Temperature responses of respiration were similar among taxa and did not appear to be contributing factors to variations in A CO2 . At 40 °C, potential photosynthetic capacity, measured under saturating CO 2 , was 4.1, 9.4, and 14.8 μmol·m -2 ·s -1 for I. rugosa, I. aquifolium , and I. cornuta , respectively (LSD 0.05 = 5.1). Variations in the relative dark-acclimated fluorescence temperature curves were used to assess thresholds for irreversible heat injury. The critical fluorescence temperature threshold (T C ) was similar (48.0 °C) for all taxa. The fluorescence temperature peaks (T P ) were 52.0, 52.8, and 53.5 °C for I. rugosa, I. cornuta , and I. aquifolium , respectively (LSD 0.05 = 0.9). Based on these results, I. rugosa was the most heat-sensitive species, followed by I. aquifolium and I. cornuta. Ilex cornuta also had substantially greater potential photosynthetic capacity than the other species at 40 °C, indicating superior metabolic tolerance to high temperatures.

Rostov] is an important disease in most cucumber ( Cucumis sativus L.) production areas of the world. Resistant cullivars are available, but higher levels of resistance are needed if yield losses are to be avoided. The objective of this experiment was to evaluate all available plant introduction accessions (from the U.S. National Plant Germplasm System), cultivars, and breeding lines (hereafter collectively referred to as cultigens) of cucumber for downy mildew resistance under field conditions in North Carolina. All available cultigens were tested in four blocks (2 yr and two replications) under natural field epidemics of the disease. Mean ratings for downy mildew leaf damage ranged from 1.3 to 9.0 on a 0 to 9 scale. The most resistant nine cultigens originated from the USA, and were primarily adapted cultivars or breeding lines. The most resistant cultigens, for which multiple‐year data were available, were Gy 4, ‘Clinton’, PI 234517, ‘Poinsett 76’, Gy 5, ‘Addis’, M 21, M 27, and ‘Galaxy’. The most susceptible cultigens for which multiple year data were available, were P1288995, P1176952, PI 178886, and P1211985. We classified 17 cultigens as highly resistant (1.3–3.0), 87 as moderately resistant (3.3–5.0), 311 as moderately susceptible (5.3–7.0), and 248 as highly susceptible (7.3–9.0) for the cultigens with multiple‐year data. No plant introduction accessions were found to be more resistant than the most resistant elite cultivars and breeding lines tested.

Cv Florida 638). Mannitol is an important photoassimilate, as well as providing plants with resistance to salt and osmotic stress. Previous work has shown that expression of the celery Mtd gene is regulated by many factors, such as hexose sugars, salt and osmotic stress, and salicylic acid. Furthermore, MTD is present in cells of sink organs, phloem cells, and mannitol-grown suspension cultures. Immunogold localization and biochemical analyses presented here demonstrate that celery MTD is localized in the cytosol and nuclei. Although the cellular density of MTD varies among different cell types, densities of nuclear and cytosolic MTD in a given cell are approximately equal. Biochemical analyses of nuclear extracts from mannitol-grown cultured cells confirmed that the nuclear-localized MTD is enzymatically active. The function(s) of nuclear-localized MTD is unknown.

Other weeds present included common cocklebur and mixed infestations of entireleaf, ivyleaf, pitted, and tall morningglories. PRE options were alachlor or alachlor plus metribuzin plus chlorimuron. Early POST options included chlorimuron, chlorimuron plus thifensulfuron, and no herbicide applied 3 wk after planting. Late POST options were chlorimuron and no herbicide applied 5 wk after planting. POST herbicides were more effective than PRE herbicides on all weeds. Chlorimuron and chlorimuron plus thifensulfuron applied early POST were equally effective on these weeds and usually more effective than chlorimuron applied late POST. There was no advantage of two POST applications compared with a single early POST application. Greatest net returns were obtained in systems using only early POST herbicides. There was no economic advantage from using metribuzin plus chlorimuron PRE in systems that included an early POST herbicide.

R. AU - Campbell, C. R. T2 - Transactions of the ASAE AB - A greenhouse experiment was done with vegetatively propagated trees to examine the influence of swine lagoon effluent on the growth and foliar nutrient content of the fast-growing hardwood species Paulownia elongata. Application of swine lagoon effluent promoted plant growth and was as beneficial as a complete chemical fertilizer applied at a similar nitrogen loading rate. Foliar concentrations of nitrogen were high, typically between 3.5% and 4.5%, when swine lagoon effluent was applied at a nitrogen loading rate equivalent to 205 or 409 kg/ha. Zinc and copper concentrations were also relatively high when plants received these swine lagoon effluent treatments (45 to 55 ppm and 17 to 23 ppm, respectively). Sufficient variation among P. elongata clones was revealed for growth parameters and foliar nutrient concentrations to anticipate a benefit from the selection of genotypes that are the most efficient for remediation of animal waste, i.e., high biomass production and foliar nutrient accumulation. The data show that P. elongata has potential for use as a swine waste utilization species.

We show that membrane association can vary in vivo in response to gravistimulation, apparently involving SuSy dephosphorylation, and is a reversible process in vitro. Phosphorylation of SuSy has little effect on its activity but decreases its surface hydrophobicity as reported with the fluorescent probe bis-ANS. We postulate that phosphorylation of SuSy (and perhaps other membrane proteins) is involved in the release of the membrane-bound enzyme in part as a result of decreased surface hydrophobicity.

April was the preferred time to harvest buds for culture, as summer buds had a high contamination frequency, and fall and winter buds did not develop well. Shoot elongation of buds collected in April (1.6 cm) was more than twice that of buds collected in February (0.7 cm) after 100 days in culture; during the same period, shoot fresh mass increased 5-fold (0.21 g in April, 0.04 g in February). Inclusion of a nitrate source reduced the frequency of bud browning, and glutamine was superior to ammonium as a source of reduced nitrogen.

The effect of four biofilter volume (BFV)/fish rearing tank volume ratios (0.67/1, 1.00/1, 1.5011, 2.25/1) on water use efficiency was evaluated.‘Laura’(first experiment) or‘Kewalo’tomatoes were grown 4/m 2 in biofilters of four different sizes and surface‐irrigated 8 times daily with water from the associated fish tanks. Daily water consumption increased with BFV/tank ratios and with time. Fish production rates increased with biofilter volume in the first experiment, but were not significantly different in the second experiment. Total tomato fruit yield per plot increased from 13.7 to 31.7 kg (Experiment 1) and from 19.9 to 33.1 kg (Experiment 2) with increasing BFV/tank ratio. For fish plus fruit, total energy production increased from 4,950 to 8,963 kcal/ plot and from 4,804 to 7,424 kcal/plot in Experiments 1 and 2, respectively, and protein production increased from 536 to 794 and from 352 to 483 g/plot in Experiments 1 and 2, respectively, with increasing BFV/ tank ratio. Trends in water use efficiency for production of food energy (kcal/L.) and of protein (g/L) in tomatoes and fish were complex.

Mid- and late-season control of mixtures of large crabgrass, goosegrass, and fall panicum by thiazopyr at 0.28 kg/ha was 89 to 97% and 11 to 50%, respectively, compared with 11 to 38% midseason and 0 to 5% late-season control by pendimethalin. Thiazopyr at 0.42 kg/ha and pendimethalin controlled broadleaf signalgrass 44 and 0%, respectively, late in the season. Adding fluometuron PRE at 1.7 kg ai/ha had little to no effect on large crabgrass, goosegrass, and fall panicum control but increased broadleaf signalgrass control 47 to 79 percentage points compared with thiazopyr or pendimethalin alone. Late-season control of annual grasses by thiazopyr or pendimethalin plus fluometuron PRE followed by methazole plus MSMA early postemergence (POST)-directed and cyanazine plus MSMA late POST-directed was at least 95% at two locations and 80% at the third location. Common lambsquarters was controlled 54 and 95% in systems without and with fluometuron PRE, respectively. Acceptable control of ivyleaf, pitted, and tall morningglories at all locations and smooth pigweed at two of three locations was achieved only in systems with POST-directed herbicides. Adding POST-directed herbicides to systems with thiazopyr or pendimethalin plus fluometuron PRE increased cotton yield at two of three locations. Treatments had no effect on fiber quality.

Furthermore, this sugar repression appears to be mediated by hexokinases (HKs) in a manner comparable to the reported sugar repression of photosynthetic genes. Glucose (Glc)-grown cell cultures expressed little MTD activity during active growth, but underwent a marked increase in MTD activity, protein, and RNA upon Glc starvation. Replenishment of Glc in the medium resulted in decreased MTD activity, protein, and RNA within 12 h. Addition of mannoheptulose, a competitive inhibitor of HK, derepressed MTD activity in Glc-grown cultures. In contrast, the addition of the sugar analog 2-deoxyglucose, which is phosphorylated by HK but not further metabolized, repressed MTD activity in mannitol-grown cultures. Collectively, these data suggest that HK and sugar phosphorylation are involved in signaling MTD repression. In vivo repression of MTD activity by galactose (Gal), which is not a substrate of HK, appeared to be an exception to this hypothesis. Further analyses, however, showed that the products of Gal catabolism, Glc and fructose, rather than Gal itself, were correlated with MTD repression.

Fruit samples from each of these cultivars were analysed for non-starch cell wall materials (NSCWM) and non-starch polysaccharides (NSP). NSCWM was further fractionated into soluble and insoluble fibre fractions. Both NSCWM and NSP content were found to be significantly influenced by cultivar. NSCWM content ranged from 19·1 g kg−1 apple flesh in ‘Fuji’ to 36·2 g kg−1 in ‘York’. Mean(±SD) NSCWM content of all the cultivars was 23·1±4·5 g kg−1. NSP content of apple flesh ranged from 13·8 g kg−1 in ‘McIntosh’ to 28·7 g kg−1 in ‘York’ with the overall mean for all cultivars being 17·9±4·2 g kg−1. Relative amount of monosaccharides found in the hydrolysates of apple fibre also varied among cultivars. The greatest difference was observed in galactose content. ©1997 SCI DA - 1997/11// PY - 1997/11// DO - 10.1002/(SICI)1097-0010(199711)75:3<333::AID-JSFA883>3.0.CO;2-R VL - 75 IS - 3 SP - 333-340 SN - 0022-5142 KW - Malus domestica KW - apple KW - dietary fibre KW - firmness KW - soluble fibre KW - insoluble fibre ER - TY - JOUR TI - Sicklepod (Senna obtusifolia) and entireleaf morningglory (Ipomoea hederacea var. integriuscula) management in soybean (Glycine max) with flumetsulam AU - Jennings, KM AU - York, AC AU - Batts, RB AU - Culpepper, AS T2 - WEED TECHNOLOGY AB - Systems consisting of flumetsulam, metribuzin plus chlorimuron, or imazaquin applied PPI with trifluralin or PRE with metolachlor were compared with and without chlorimuron POST for control of sicklepod and entireleaf morningglory in narrow-row soybean at four locations. Control of sicklepod and entireleaf morningglory by soil-applied herbicides was generally inadequate. Control of sicklepod by flumetsulam exceeded control by metribuzin plus chlorimuron or imazaquin at one location. Entireleaf morningglory control by flumetsulam was similar to or less than control by metribuzin plus chlorimuron or imazaquin. Chlorimuron POST was a more important component of management systems for these weeds than was flumetsulam, metribuzin plus chlorimuron, or imazaquin PPI or PRE. Pooled over soil-applied herbicides, chlorimuron POST increased late-season control of sicklepod and entireleaf morningglory 25 to 61% and 22 to 54%, respectively; increased soybean yield 20 to 55%; decreased foreign matter contamination 5 to 13%; and increased net returns $34 to $185/ha. When used in conjunction with chlorimuron POST, flumetsulam, metribuzin plus chlorimuron, and imazaquin applied PPI with trifluralin or PRE with metolachlor increased late-season control of sicklepod and entireleaf morningglory only when control by trifluralin or metolachlor followed by chlorimuron POST was less than 66 and 77%, respectively.

Eleven methods of calculating heat units were chosen for comparison based on their performance as described in the literature. The most reliable method was defined as the one with the smallest coefficient of variation (CV). CVs were calculated for each method over both seasons and locations, for each season over all locations, each location over all seasons, and for each season at each location. All heat unit summation methods had smaller coefficients of variation (CV) than the standard method of counting days from planting to first harvest. Heat unit summation methods improved harvest date prediction accuracy compared with the counting day method for tomatoes in the South Atlantic Coast (SAC) region. Prediction using location/season specific models were less variable than the models over all seasons and locations. Incorporating daylength improved model prediction accuracy when applied over all locations and seasons, all locations by season, and all seasons by location. Based on the results of this study, the heat unit summation technique recommended for this region (where the location and season specific models are not available) is the reduced ceiling method multiplied by daylength.

Parents, F1 F2 and BC1 to both parents of a cross between Sumter (Cucumis sativus var. sativus) and LJ 90430 were evaluated in two greenhouse experiments to determine genetics of resistance to M. javanica. All F1 progeny were susceptible, and segregation ratios in the F resulted in 1 resistant:3 susceptible. Backcross progeny to the susceptible parent were susceptible, and the BC1 to the resistant parent segregated 1 resistant:1 susceptible. Reciprocal crosses did not differ and therefore showed no evidence of maternal or cytoplasmic effects. Results from the crosses of several inbreds (Addis, Gy 14, Gy 57u, Poinsett 87, and Sumter) with LJ 90430 indicated that use of those five different genetic backgrounds had no influence on gene expression. The five F2 families segregated in a 1 resistant: 3 susceptible ratio. The five BC, (to LJ 90430) families segregated in a 1 resistant:1 susceptible ratio. F3 families were developed from resistant and susceptible F2 plants using the five inbreds. Resistant F2:3 families produced progeny that were all resistant, and susceptible F2:3 families fit a ratio of 1 susceptible:2 segregating. Thus, resistance to M. javanica is conferred by a single recessive gene for which we propose the symbol mj.

The response to quinclorac in two susceptible grasses, barnyardgrass and smooth crabgrass, was compared to a tolerant species (rice) and a resistant biotype of smooth crabgrass. In whole plant studies, quinclorac completely inhibited root elongation in susceptible grasses at 10 μM. At the same herbicide concentration, cell wall biosynthesis in the susceptible grasses was reduced by 60 to 73%; after a 6-hr treatment, but inhibited by only 20 to 36%; in the tolerant grasses. Increasing treatment time to 24 hr had little additional response. The effect of quinclorac on cell wall synthesis was dose dependent between 0 and 10 μMand corresponded closely with the dose-dependent response in root growth of susceptible grasses. All the cell wall constituents in barnyardgrass, including cellulose and several hemicellulose fractions, were inhibited 30 to 50%; more than those of rice. Root accumulation of [14C]quinclorac was greatest in barnyardgrass and rice and lowest in the two biotypes of smooth crabgrass. These results are consistent with a mechanism of action in which quinclorac acts as an inhibitor of cell wall biosynthesis in sensitive grasses. Selectivity among different grasses could be explained by differential sensitivity at the site of action.
