Abstract |
: |
Intact seedlings of ten days old Vicia faba L. were trated with fusilade and herbstop in 5 concentrations: 10 , 50 , 100 , 300 and 500 ppm. Root samples were examind after different intervals. The two herbicides affected mitotic activity, mitotic stages and produced chromosomal aberrations with different percentages in root-tips of Vicia faba L. The two herbicides increased metaphase frequancey in all treatments Abnormalities produced were laggards, bridges, C-metaphase, 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 results of arresting metaphase, spindle poisoning, inhibition of cytokinesis, chromosome breakage and changing of chromatin chemical compositions. The results suggested possible mutagenic potential of the two herbicides. |
