The Mutagenic Activities of Uccmaluscide Using Vicia faba as a Biological System

Abstract

The effect of the molluscicide “Uccmaluscide” on mitosis and meiosis of Vicia faba has been studied. Mitotic activity of Vicia faba root tip cells decreased and produced different kinds of chromosomal abnormalities after treatment with different concentrations. Vicia faba plants were sprayed at flowering stage with the different concentrations of uccmaluscide solution. The percentage of abnormal pollen mother cells increased as the concentration increased. The most dominant types of abnormalities were stickiness, bridges, fragments of chromosomes, disturbance of mitotic stage and littlepolar or multipolar cells. Less than 4 spores were the dominant type of abnormalities observed in the quartet stage. Nonviable pollen grains were observed in addition to the small pollen grains.
