Abstract
To observe the stimulating effects of low dose γ-radiation on the dormancy breaking and physiological activity, potato (Solanum tuberosum L. cv. Dejima) were irradiated at the dose of 0.5 ∼ 30 Gy. Low dose γ-radiation had promoting effects on the srouting rate the optimum dose of 1 Gy and 2 Gy and on the sprout length at the optimum dose of 2 Gy and 4 Gy. In case of number of sprouts, there were increased in all of the low dose irradiation groups and period storages, which showed very significant promoting effects at 4,8,16 Gy of 15 DAP. The field growth of 45 DAP were increased at all of the low dose irradiation group, which particularly were very significant promoting effect at 4 Gy irradiation group. Irradiation didn't have significant effects on the antioxidant enzyme activity of potato plantlet, but the peroxidase activity of 45 DAP plantlet increased at 4 Gy irradiation group
