Mutagenicity of two herbicides fusillade and herbstop in Vicia Faba L.

Abstract EN

Intact seedlings of ten days old Vicia [aba L.

were treated with fusillade and herb stop in 5 concentrations : 10, 50, 100, 300 and 500 ppm .

Root samples were examined after different intervals.

The two herbicides affected mitotic activity, mitotic stages and produced chromosomal aberrations with different percentages in root-lips of Vida [aba L.

Thc two herbicides increased metaphase frequency in all treatments.

Abnormalities produced wer~ laggards , bridges, Cvmetaphase, tripolar nuclei.

polyploidy cells, fragments.

binucleate cells and stickiness of chromosomes.

The abnormalities appeared during 5 hours after the beginning of the experiment.

These cytological alterations can be explained as a result of arresting metaphase, spindle poisoning, inhibition of cytokinesis, chromosome breakage and changing of chromatic chemical compositions: The results suggested possible mutagenic potential of the two herbicides .
