Tn the seed treatment no germination was noticed above 30 KR whereas in capsule treatment a few sprouts were noticed at 40 KR, but germination was not noticed above 40 KR. The percentage of germination was observed to be inversely proportional to the dose of gamma rays indicating the lethality of high doses in the life process of the seedlings. The percentage oflger-mination is highly influenced by moisture content of the seed. The LD-50 appears to be around 10 KR.enArticle
