Mutagenesis induced with dioxidin in the Allium-test

Cytology and Genetics 2006, v 40, number 5, 31-35

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.
