Abstract
Vicia faba seeds (var. Giza 1) were irradiated with: 500, 1000, 2000, 4000, 6000, 8000, 10, 000r of Co60 γ-radiations.
A rapid increase in the percentage of abnormal cells in root-mitosis was observed as the employed dose increased from 8000 to 10, 000 r. The same doses affected a high degree of inhibition in root-growth. The change in the normal cells was proportional with the given doses. Micronucleated cells represented the most dominent type of anomalies affected by irradiation.
Plants originated from irradiated seeds recovered. A significant percentage of abnormal PMCs was observed only in plants originated from seeds irradiated with 10, 000 r.
