Abstract:
The present study was conducted to examine the impacts of gamma irradiation on seed germination and morphological traits of Pisum sativum L. For this purpose, dry and healthy seeds of Pisum sativum were exposed to different doses of gamma radiations viz. 150Gy and 200Gy at the Bhabha Atomic Research Center (BARC). The result showed that the gamma irradiation affected germination percentage, plant survival and morphological characteristics such as plant height, pod number, pod length, seed number and grain weight. It was observed that all the trait showed decreasing trend in there mean value with the increasing intensity of gamma irradiation. However, in 150Gy irradiation dose showed the slightly increase in plant height with respect to control set. The highest doses of gamma rays 200Gy exposure caused death of all seedlings and no seed germination was observed.
