Importance of the type of soil for the induction of micronuclei and the growth of primary roots of Vicia faba treated with the herbicides atrazine, glyphosate and maleic hydrazide.
Research was carried out on the genotoxic effects (induction of micronucleated cells in primary root tips) and toxic effects (reduction in primary root growth) in young plants of Vicia faba grown in soils with different organic matter contents and treated with the herbicides atrazine, glyphosate and maleic hydrazide. The data obtained show that the genotoxic effects are noticeably influenced by the interactions between the herbicide and the type of soil in which the Vicia faba have grown. While maleic hydrazide proved to be highly clastogenic for young plants grown in both soils, atrazine was genotoxic only in young plants grown in soil poor in organic matter. Glyphosate did not induce micronuclei under either soil condition, but induced a significant toxic effect.
