摘　　要：用 2 5 0、30 0、35 0和 40 0Gy 4种不同剂量的60 Coγ射线照射鄂恩 4号小麦干种子 ,测定了照射后及时播种和贮藏 1 5 0d播种对小麦的发芽势、发芽率、幼苗高、幼苗根数和根长的影响。结果表明 :被照射的小麦种子 ,贮藏 1 5 0d后 ,较及时播种的小麦种子其发芽和生长得到了一定程度的恢复 ,即贮藏减轻了辐射损伤 ,但辐射效应仍然存在。Wheat dry seed of EN 4 is radiated at doses of 250,300,350 and 400Gy by 60 Co γ-ray.Irradiation effects on germination energy,germination capacity,seedling height,primary root number and root length of the wheat seed sowing after storing 0 and 150 days after radiation are measured.The results show that the germination and growth ability of wheat seed after storing 150 days are recovery compared with the wheat seed sowing right after irradiation.The radiation effects still exist after the 150d storage,but the radiation damage could be relieved by storage.
