以小麦品种宁春4号为指示材料，研究了浓度为100、300、500μmol/L的CuCl2对小麦幼苗抗氧化酶（CAT、POD和APX）活性的影响。结果表明，随着Cu2+胁迫浓度的增加，小麦幼苗叶片过氧化氢酶（CAT）和过氧化物酶（POD）活性显著上升，且有相似的变化趋势，在Cu2+胁迫浓度为300μmol/L时活性最高。抗坏血酸过氧化物酶（APX）活性在100μmol/L浓度下降低，由300μmol/L增加到500μmol/L时先升高后降低。

The Ningchun 4 wheat was used as a material in this test,which studies the influence of the activity on wheat seedling antioxidant enzymes(CAT,POD and APX),under the different concentration(100 μmol/L,300 μmol/L,500 μmol/L、) CuCl2 . The results showed that the increase of Cu stress concentration,the activity of wheat seedling leaves catalase (CAT)and peroxidase (POD) rises significantly,and have a similar changing trend . When the concentration of enzymatic is 300 μmol/L, enzymatic is the most active . But when ascorbic acid peroxidase (APX)is 100,μmol/L the activity of enzyme is living lower . And the concentration of enzymatic was 1 300μmol/L and 500μmol/L,it increases firstly,and then decreases .
