Abstract
Dry seeds of Sudan grass (Sorghum bicolor (L.) Moench,) were subjected to chronic and acute irradiation treatments ranging from 10 to 10.0 kR, The sources of irradiation were 850 curies fiCen gamma beam for chronic irradiali,Ln and 4000 cuties 6r,]Co gamma cell for acute irradiation, Seedling gerrniu ability in the laboratory -1...as not ger;erIlly affected by the iri adiation treatments. However, seedling b.eigber decreased measurably with intreasing treatments of irra.diatior. and the Setdlings expo.scd to treatments beyond 70 kR did not survive. This suggests that such levels of irradiation are lethal to Om growth, Treatments of 10 kR to 70 kR did not have any noticeable depressing effect on tillering when compared to unirradiated seeds. Differences in dry matter coriteits due to variation in irradiation were not significant with the exception of 10 and 30 kR treatments which gave L.ubstantiatly hither dry matter contents.
