摘要
用1—10KR的^(60)Coγ射线处理籼稻品种双丛169—1的陈种子,结果表明:低剂量辐照对发芽率、成苗率、根长、主茎带蘖数及地上部干物重有不同程度的促进作用.但对苗高有一定的抑制效应。
Results in this experiment show: by irradiating the stored seeds of rice variety "Shuang cong 169-1" With low-dose^(60)Co-r rays from 1 to 10 KR, germination percentage, seedling survival rate, root length, the number of tiller per plant and dry weight of aboveground seedling are stimulated to differens extens, but seedling height is somewhat restrained.
