【摘要】 用20 Gy 、30Gy 和40Gy 60Co γ射线照射黄瓜种子,用10Gy 、20 Gy 和40Gy 剂量照射番茄种子,在停照后6 、12 、24 、48 和72h 测量干种子和萌动种子超弱发光强度。结果表明,在低剂量辐照范围内,超弱发光强度随辐照剂量增大而增大,种子萌动期发光强度大于干种子,经10Gy 处理的番茄种子发光强度一直高于其它处理及对照组。更多还原

【Abstract】 Cucumber seeds were irradiated with 60 Co\|γ rays of 20Gy, 30Gy, 40Gy,and tomato seeds were irradiated with 60 Co\|γ rays of 10Gy, 20Gy, 40Gy.Then ultraweak luminescence intensity of dry seeds and sprout seeds were measured in 6,12,24,48,72hours after irradiation. The results showed that ultraweak luminescence intensity increased with the irradiation dose in the range of low\|dose.Luminescence intensity at germination stage was stronger than that of dry seeds.Luminescence intensity of treated tomato seeds was higher than other dose treatments and CK.更多还原
