متن کاملAtrazine Resistance in a Velvetleaf (Abutilon theophrasti) Biotype Due to Enhanced Glutathione S-Transferase Activity.
We previously reported that a velvetleaf (Abutilon theophrasti Medic) biotype found in Maryland was resistant to atrazine because of an enhanced capacity to detoxify the herbicide via glutathione conjugation (JW Gronwald, Andersen RN, Yee C [1989] Pestic Biochem Physiol 34: 149-163). The biochemical basis for the enhanced atrazine conjugation capacity in this biotype was examined. Glutathione l...
متن کاملMicroarray analysis of late-season velvetleaf (Abutilon theophrasti ) effect on corn
Sharon A. Clay Department of Plant Science, South Dakota State University, Brookings, SD 57007 Microarray analysis was used to identify changes in gene expression in corn leaves collected from plants at the V11–14 growth stage that resulted from competition with velvetleaf. The plants were grown in field plots under adequate N (addition of 220 kg N ha 1) and irrigation to minimize N and water s...
متن کاملMining the record: historical evidence for climatic influences on maize –Abutilon theophrasti competition
Variations in climate are widely recognized as central factors governing the competitive balance in mixedspecies plant communities. In agricultural systems, highly variable patterns of crop yield reduction as a function of weed density have been documented across sites and among years at the same site for several crop–weed combinations. This variation is typically attributed to contrasting envi...
متن کاملInhibition of Velvetleaf (Abutilon theophrasti) Germination and Growth by Benzyl Isothiocyanate, a Natural Toxicant!
/ Abstract. Benzyl isothiocyanate (BITC) was extracted from mature papaya (Carica papaya L.) seeds and applied to imbibed velvetleaf (Abutilon theophrasti Medic. #3 ABUTH) seeds. Complete inhibition of germination occurred at a concentration of 6 x l(f4 M BITC, and only 28% (compared to controls) of the seeds germinated after 4 days exposure to the 4 x l(f4 M treatment. Corn (Zea mays L. 'DeKal...
