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。 Eighty-nine Leguminosae species and seeds were irradiated with different dosages of ~ (60) Co-γ rays. According to the multi-target click model Y = 1- (1-e ~ (γD)) ~ Curve, the appropriate radiation doses of 89 leguminous species and varieties of seeds were obtained by computer processing, and their radiation sensitivity was analyzed comprehensively. It was pointed out that the radiation sensitivity of different species and varieties was affected by many factors Restrictions.
