摘要
桑树超氧物歧化酶（ＳＯＤ）活性在不同品种、不同叶位和不同器官之间表现较大差异，有成熟叶＞嫩叶，韧皮部＞木质部，细根＞须根以及叶片＞新梢＞根系的倾向．桑叶中有３～５种ＳＯＤ同工酶。
Studies find that the activity of superoxide dismutase (SOD) shows great differences in various varieties,leaf orders and organs in mulberry with the following tendency:mature leaf>tender leaf,phloem>xylem;rootlet>fibrous root;and individual leaf>shootlet>root system. It is also found that there are 3 5 kinds of SOD isozymes in mulberry leaf,while there are 5 6 kinds in shootlet and root system.
