以不同剂量的６０￣Ｃｏγ射线对大豆风干种子进行诱变处理后，对当代植株的生理指标及农艺性状进行测定分析表明，辐射对当代植株过氧化氢酶活性有明显影响，植株粗蛋白质含量随辐射剂量增加而增加，造成生理机能失调，从而抑制植株生长发育；辐射对植株干物质合成的影响，以高剂量影响较大。当代植株的叶形、根瘤及农艺性状等均有变异。研究表明，诱变大豆的辐射剂量以１０～１４ＫＲ为宜。 After different doses of 60Coγ-rays were used to mutate the dried seeds of soybean, the physiological and agronomic traits of the contemporary plants were measured and analyzed. The results showed that the radiation had a significant effect on the catalase activity of the plants. The crude protein content Radiation dose increased and increased, resulting in physiological dysfunction, thereby inhibiting plant growth and development; radiation on plant dry matter synthesis, with a greater impact on high doses. Contemporary plant leaf shape, nodules and agronomic traits have variations. Studies have shown that the radiation dose of mutagenized soybeans to 10 ~ 14KR appropriate.
