Effect of gamma irradiation on OKRA (Abelmoschus esculentus L.)

2018

The investigation was carried out to evaluate the effect of different doses of gamma rays (100, 200, 300, 400, 500Gy and zero doses as control) on various morphological aspects of Abelmoschus esculentus. A comparison of the results of different doses with control showed that gamma irradiation significantly affected various parameters. Days to germination were almost the same as compared to control, but 400Gy took minimum days to germination. Germination % was 100% both in control and the irradiated plants. 100Gy took minimum days for flower initiation as compared to control and other doses. Fruit initiation early occurred in 100Gy as compared to other doses, and fruit maturation occurred early in 300Gy as compared to control. Plant height was significantly increased at 500Gy as compared to control. Number of fruits per plant was significantly decreased at 200Gy as compared to control. Fruit length decreased in all doses but in control fruit length was maximum. Number of seeds per fruit was maximum at control, fresh and dry weights of seeds were increased in control as compared to other doses. The number of nodes decreased in all doses but in the control the numbers of nodes were maximum. Branches were increased in100Gy as compare to 200, 300,400,500Gy as well in control. Numbers of leaves were increased in 300Gy as compared to other doses.
