| 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。

| Abstract: | 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 ~(60)Co-γ ray、NaN_3 and space radiation showed stimulation effects. The order of germination index of 3 treatments was NaN_3 >~(60)Co-γ ray > space radiation;as for main root length, it was space radiation >NaN_3>~(60)Co-γ ray;and for root fresh weight, it was space radiation >~(60)Co-γ ray>NaN3;for stem and leaf fresh weight, it was space radiation >NaN_3 >~(60)Co-γ ray. |
