| 摘 要： | 为了探讨60 Co-γ射线照射对垂穗鹅观草主要生物学性状的影响,采用不同剂量60 Co-γ射线照射垂穗鹅观草干种子,研究辐射处理后种子萌发特征及植株主要农艺学性状变化。结果表明:辐射剂量低于或等于50Gy可促进垂穗鹅观草种子的萌发,大于50Gy种子萌发能力下降。辐射半致死剂量为148Gy,适宜剂量范围是0～148Gy。辐射处理对株高、分蘖、叶宽、穗长和产量等主要农艺学性状有一定的影响。30Gy处理后株高、分蘖、叶宽、穗长和产量都高于对照,分别比对照高16.6%、43.0%、16.2%、9.65%和25.5%。

| Abstract: | In order to discuss mutagenic effects of 60Co-γ ray radiation on the main biological characteristics of Roegneria nutans(Keng)Keng,and provide basic data for the applying of radicalization technology in Roegneria nutans(Keng)Keng breeding,dry seeds of Roegneria nutans(Keng)Keng were irradiated with different dose.Seed germination characters and the main morphologic status were studied.The results showed that:Doses that below 50 Gy could promote seed germination and descent when doses beyond 50 Gy.Determination of half lethal dose was 148 Gy,so the appropriate induced dose was found to be from 0 to 148 Gy.60Co-γ ray radiation had an obvious effect on main morphologic characteristics,the plant height,trillers,leaf width and yield were 16.6%,43.0%,16.2% and 25.5% higher than those of the control. |
