Inhibition 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...
متن کاملGermination Patterns in Naturally Chilled and Nonchilled Seeds of Fierce Thornapple (Datura ferox) and Velvetleaf (Abutilon theophrasti)
Seeds from natural populations of fierce thornapple and velvetleaf collected in a corn-growing area in central Spain were incubated at a range of constant temperatures and water potentials to model the progress of germination on the basis of the accumulation of hydrothermal time. Previous to the germination tests, the seeds were treated in two different ways: (1) dark storage under dry conditio...
متن کاملComparison of efficacy, absorption and translocation of three glyphosate formulations on velvetleaf (Abutilon theophrasti).
Growth analysis, absorption and translocation studies were conducted to compare a 1-aminomethanamide dihydrogen tetraoxosulfate (GLY-A) formulation of glyphosate with two isopropylamine (GLY-IPA-1, GLY-IPA-2) formulations of glyphosate on velvetleaf. The two isopropylamine formulations differed by the presence of a surfactant in the formulation, GLY-IPA-1 containing surfactant whereas GLY-IPA-2...
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...
