摘　　要：以不同剂量的￣（６０）Ｃｏ－γ射线照射１１个属８９个豆科牧草种和品种种子，按多靶单击模型Ｙ＝１－（１－ｅ￣（γＤ））￣ｎ拟合效应曲线，经电子计算机处理求出了８９个豆科牧草种和品种种子的适宜辐射剂量，并就它们的辐射敏感性进行了综合分析，指出不同牧草种和品种的辐射敏感性受多种因素所制约。Seeds of 89 forage legumes from 11 genera were treated with￣(60)Co- γ ray of different dosages.Suitable dosages for the seeds were figured out by using the'multitarget-sin-gle hitting'model of Y=1-(1-e￣(γD))￣n and the application rate-effect curve was estab-lished by computer simulation。 The 89 legumes were classified into different groups based on their radiation sensitivities and the factors affecting the sensitivities were dis-cussed.
