对萌发过程中野生和栽培大豆SOD同工酶分析表明:1.供试野生大豆和栽培大豆的SOD同工酶谱带明显不同,野生大豆含有M_n—SOD_a、C_u—Z_n—SODb_1b_2b_3和C_u—Z_n—SODc_1c_2c_3,栽培大豆缺失C_n—Z_n—SODb_1b_2谱带,而且两种类型的C_u—Z_n—SODc_1c_2c_3谱带的迁移率也不完全一致。2.萌发过程中,以单位鲜重计算的SOD活性的变化进程为,萌发初期迅速降低,然后逐渐增加。3.萌发过程中,SOD活性及活性的变化程度均表现野生大豆>栽培大豆。
The SOD isoenzymes of wild and cultivated soybean during germination showed that: 1. The isoenzyme bands of SOD in the tested wild soybean and cultivated soybean were significantly different. The wild soybean contained M_n-SOD_a, C_u-Z_n-SODb_1b_2b_3 and C_u-Z_n -SODc_1c_2c_3, C_n-Z_n-SODb_1b_2 bands were lacking in cultivated soybean, and the mobility of the two types of C_u-Z_n-SODc_1c_2c_3 bands was not exactly the same. In the process of germination, the change of SOD activity calculated from fresh weight per unit area decreased rapidly in the early germination stage and then gradually increased. In the process of germination, the changes of SOD activity and activity all showed wild soybean> cultivated soybean.
