    Journal: Zhongguo Zhong Yao Za Zhi; 2007 Jun; 32(11):1016-8. PubMed ID: 17672331.
    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.
