摘要
分别用60Co-γ射线、NaN3和航天诱变3种不同诱变方式以不同剂量处理普那菊苣Cichorium intybuscv.Puna种子,对诱变处理后种子的发芽情况和幼苗的性状进行了室内观测,结果表明:60Co-γ射线、NaN3和航天诱变对普那菊苣种子的萌发具有不同程度的刺激效应。其中发芽指数表现为化学诱变>辐射诱变>航天诱变;主根长度表现为航天诱变>化学诱变>辐射诱变;根系鲜质量表现为航天诱变>辐射诱变>化学诱变;茎叶鲜质量表现为航天诱变>化学诱变>辐射诱变。
The seeds of Cichorium intybus cv. Puna were treated by γ-ray, NaN3 and space radiation and the seed germination and seedling growth characters were determined in laboratory. The results indicated that ^60Co-γ ray,NaN3 and space radiation showed stimulation effects. The order of germination index of 3 treatments was NaN3：^60Co-γ ray 〉 space radiation; as for main root length, it was space radiation 〉NaN3〉^60Co-γ ray; and for root fresh weight, it was space radiation ^60Co-γ ray〉 NaN3〉 for stem and leaf fresh weight, it was space radiation 〉NaN3〉^60Co-γ ray.
