Abstract
The variations induced by x-irradiation of seeds ofAbelmoschus esculentus in X1 generation have been studied. Percentage of germination showed a slight increase in treatments at 1 to 3 kR, while at the higher doses there was a gradual decrease in germination. Seedling growth measured at regular intervals of 6 hr up to 96 hr, showed that growth rate was reduced and germination delayed at doses of 8 to 10 kR. Lateral root number and length were not significantly effected by the dosage rate. Total chlorophyll content of leaves was reduced by 50% at 8 kR treatment, while an increased chlorophyll metabolism was observed at doses of 4 and 7 kR. Increasing dose rate caused a gradual decrease in plant height. Early flowering was induced in 8, 9 and 10 kR treatments, while flowering was delayed in the 5 and 6 kR treated samples. Average pod length did not show significant variations between the different dose rates as was also the stomatal index. Increased seed weight was observed in samples treated above 8 kR.
