将紫花苜蓿（ Medicago sativa L．）10个品种种子经2000 Gy剂量的60 Co－γ射线辐射处理，并就辐射处理对其部分生长和营养指标的影响进行了比较分析．结果显示，经60 Co－γ射线处理后，10种紫花苜蓿种子的萌发率、株高和营养指标等都发生了不同程度的变化．辐射处理对先行者、 WL525、 WL903和Adrenalian等紫花苜蓿品种种子萌发率的影响较小，而明显降低了其余大富豪、阿尔冈金、费纳尔、苜蓿王、标杆和WL2321等6个品种的种子萌发率；辐射处理对部分紫花苜蓿品种的生长速度有促进作用，而对部分品种的生长速度有抑制作用；辐射处理对大部分品种的粗蛋白、总糖、总氨基酸浓度有显著增高或降低作用，但对全部品种的干／鲜质量比无显著影响．

Ten Medicago sativa L.varieties were radiated by 2 000 Gy 60 Co-γray, and some growth and nutrition indexes were analyzed.The results showed that the germination rate, plant height and nutritional quality changed at different degrees after the radiation.The germination rates of six varieties, Million-aire, Algonguin, Fnal, Alfaking, Beraga and WL2321, were decreased by the radiation with no effect on those of four varieties, Xianxingzhe, WL525, WL903 and Adrenalian.Growth speed of partial varieties increased and that of partial varieties decreased after the radiation.Crude protein, total sugar and total a-mino acid contents of most varieties increased or decreased significantly but dry/fresh weight ratio of all changed with no significant difference after the radiation.
