Trans-location and degradation of bromoxynil in a resistant and a susceptible species.

摘要: The relation of translocation and degradation to selectivity 3,5-dibromo-4-hydroxybenzonitrile (bromoxynil) in winter wheat (Triticum aestivum L., var. Nugaines), a resistant species, coast fiddleneck (Amsinckia intermedia Fisch. &z Mey.), susceptible was examined. Radioautographic extraction analysis revealed that the label from GC-bromoxynil more mobile than wheat. Higher levels soluble radioactivity were found extracts insoluble tissue residues fiddleneck. In both most activity remained treated leaves. A high percentage attributed "4C-bromoxynil evolution "4CO2 by with significantly exceeded difference susceptibility between appears be explained partly differential bromoxynil.
