小麦抗锈病品种抽穗期叶片中ＳＯＤ和ＣＡＴ活性较低，Ｏ_２产生速率较高；但籽粒形成期之后能保持较高的ＳＯＤ、ＣＡＴ活性，（积累较少，细胞膜脂过氧化水平较低，叶绿素和脯氨酸含量较高。感病品种则相反。
The activities of SOD and CAT in heading stage of wheat rust resistant cultivars were lower and the production rate of O 2 was higher. However, the SOD and CAT activities of wheat cultivars with rust resistance were higher after the formation of grains (less accumulation, lower lipid peroxidation, And proline content is higher. The susceptible species is the opposite.
