分别用~(60)Co-γ射线、NaN_3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 intybus cv.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:~(60)Co-γ射线、NaN_3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.
分彆用~(60)Co-γ射線、NaN_3和航天誘變3種不同誘變方式以不同劑量處理普那菊苣Cichorium intybus cv.Puna種子,對誘變處理後種子的髮芽情況和幼苗的性狀進行瞭室內觀測,結果錶明:~(60)Co-γ射線、NaN_3和航天誘變對普那菊苣種子的萌髮具有不同程度的刺激效應.其中髮芽指數錶現為化學誘變>輻射誘變>航天誘變;主根長度錶現為航天誘變>化學誘變>輻射誘變;根繫鮮質量錶現為航天誘變>輻射誘變>化學誘變;莖葉鮮質量錶現為航天誘變>化學誘變>輻射誘變.

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.
