The effect of Gamma Radiation on Growth in Sweet Sorghum
Abstract
Dry seeds of sweet sorghum cultivar Wray were treated with gamma rays from Cs-137 source at the Department of Applied Rediation and Isotopes, Kasetsart University. The dosages of gamma rays were 0, 300 and 400 Gy. Agronomic character changes were observed on M1 generation at the Central Laboratory and Greenhouse Complex Kamphaengsaen, Nakhon Pathom. The height of plants from the irradiated seeds was reduced with each dosage of 300 and 400 Gy especially in the earlier stages of development but showed no effect in later stages. All radiation dosages not only decreased pollen fertility but also delayed the anthesis. Gamma irradiation did not effect on net weight of stripped stalk.
