Abstract:
The cytogenetic effects of dichlorvos on Hordeum vulgare L. seeds
were
investigated. Seeds of H. vulgare were treated with different
concentrations of dichlorvos and applied for
increasing
concentrations of dichlorvos (0.01, 0.05, 0.1, 0.5 and 1 mg/L) and
increased treatment period (10-, 24- and 48-hour) decreased the
mitotic index compared with the untreated control. The inhibitory
effects of dichlorvos on the mitotic index
indicated its genotoxic and mutagenic effects on H. vulgare
seeds. It can be concluded that DDVP clearly poses a genotoxic risk. The
results of the present study are fundamental results and provide
direction for future investigations.
