Abstract
A germination method was used to detect biological changes in gamma-irradated apple, orange, and lemon at low doses at 0.1, 0.3, 0.5, 0.7, and 1.0 kGy. Ten fruit seeds of each sample were placed on moistened cotton and germinated at 3$0^{\circ}C$ for 7 days. Shoot lengths of all fruits were gradually grown for 7 days, but the growth was signficantly slow down by fifth day. During 7 days of germination, the growth of unirradiated fruits were significantly highter than the irradiated fruits. By examining the gamma-Irradiated fruits in this study, a germination method could be possibly one of the screening test to identify irradiated fruits.
