摘要
本文对不同进化类型大豆种子超氧物歧化酶(SOD)进行了比较分析。结果表明:(1)供试三种进化类型大豆种子的 SOD 同工酶酶谱一致,均为7条,其中一条为 Ma-SOD,其余6条为 Cu-Zn-SOD。(2)SOD 活性表现为:野生类型明显高于中间类型,中间类型明显高于栽培类型。(3)随着大豆籽粒百粒重的增大,种胚的 SOD 活性降低。(4)种皮颜色由黑到黄,种皮的 SOD 活性降低。讨论了大豆种子 SOD 活性与 Sofa 亚属内大豆进化的关系。
The SOD isoenzymes of different soybeans were studied in this experiment and the results. showed that:1.there were 7 SOD isoenzyme bands in all soybean genotypes used in this ex- periment,2.the SOD activity(unit/g fr.wt.)in different soybean seeds decreased as the evolutionary process advanced,3 the SOD activity decreased as the wt./100 seeds increased, and the color of seed coat changed from black to yellow.The relationship between SOD ac- tivity and the evolutionary process was discussed.
