Abstract

The analysis of some cytogenetic parameters shows that the lead acetate application on Favorit andPR64A83 cultivars of sunflower exercises a light mutagen effect on the cells of the root apex. At same time anintensification of the frequency of the ana-telophases with aberration takes place, especially of those with bridges, withlagging and expelled chromosomes, but also of those with fragments, demonstrating the perturbation action that substanceexercises on the division axle. The presence of ana-telophases with fragments proves that this substance induces breachesat the chromosomal level (clastogenic effect)
