To study the changing rules of SOD and protein during the germination of mung bean,mung beans of different germination durations are taken as the research object, according to NBT light. The activity of SOD in different parts of mung bean was determined by chemical reduction method. Protein content was determined by Coomassie Brilliant Blue G-250 method. The results showed that the activity of SOD was highest in mung bean on the 5 d of germination. There was a significant difference in SOD enzyme activity of mung beans with different germination time. The activity of SOD in different parts of mung bean germination was significantly different. The highest SOD activity was root, and the SOD activity was 3 and 5 times that of embryo and stem,respectively. Protein content increased during germination.
