| 摘 要： | 目的：研究γ射线对薏苡诱变效应。方法：用薏苡干种子作为诱变材料,以M1代发芽率、成苗率、苗高、根长为生理效应指标,以M2代叶绿素突变为诱变效应指标进行了相关诱变研究。结果：γ射线对幼苗生长有明显的抑制作用,具有较强的诱发叶绿素突变的能力。结论：γ射线是一种对薏苡有效的诱变剂。薏苡干种子诱变时γ射线的适宜剂量为450 Gy。

| Abstract: | Objective: To study the mutagenic effect of gamma-rays on Coix lacryma-jobi var.ma-yuen. Method: Physiological and mutagenic effects of gamma-rays on C. lacryma-jobi var.ma-yuen dormant seeds were studied.The germination percentage, seeding survival, seeding height and root length of M1 plants and the frequency of chlorophyll mutation in M2 generation were selected as criteria. Result: The gamma-rays showed obvious inhibitory action to the seedling growth, and a strong ability in inducing the chlorophyll mutation. Conclusion: The gamma-rays is one kind of C. lacryma-jobi var.ma-yuen effective mutagen. The appropriate dose of gamma-rays is 450 Gy for C. lacryma-jobi var.ma-yuen dormant seeds. |
