Abstract

Treatment of vicia faba L.with different concentrations of cumicidin and curacrone for 3,6,12 and 24 h, showed chromotoxic effects on mitotic and meiotic cells. Both compounds reduced the mitotic activity and resulted in accumulation of metaphase cells, where other phases are reduced with few exceptions. Effects also include inhibition of cell division and induction of chromosomal abnormalities. The percentage of mitotic abnormalities increased as the concentration of the insecticide increased and when the time of treatment is prolonged. Types of abnormalities as c-metaphase, stickiness, disturbed, bridges and Lagging were observed.
