[Mutagenesis induced with dioxidin in the Allium-test].
The influence of dioxidin in different concentrations (10-100 mg/l) on the cytogenetic parameters of Allium cepa L. has been studied. The mutagenic effect of dioxidin was shown within all the range of the studied concentrations. The curve "dose-effect" has been determined for the concentrations of 10, 20, 30, 40, 50, and 100 mg/l. The peak of the mutagenic effect and significant reduction of the mitotic index were revealed at the concentration of 100 mg/l. It was shown that the mutagenic efficiency of the dioxidin statistically correlated with reduction of the mitotic activities.
