| 摘 要： | 以巴西陆稻IAPAR9及典型水陆稻品种为材料，研究其超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD) 在干旱胁迫下的活性变化.结果表明：相关酶活性以SOD、POD酶活性变化较能反映稻品种的抗旱性，其变幅大小可作为稻品种抗旱性评价的良好生化指标；CAT酶活性则变化复杂，不宜作稻品种抗旱性指标.IAPAR9具较高的POD酶活性水平，中等SOD、CAT酶活性水平.

| Abstract: | This paper studied the rules of some oxidase activities’ changes such as SOD,POD and CAT of Brazilian Upland Rice IAPAR9 and typical rice varieties under drought stress.The results showed that:correlative enzyme activity such as SOD and POD could express drought resistant ability of rice varieties,and their varied range might be taken as good biochemical indices of evaluating drought resistant ability of rice;CAT activity varied complicatedly,so it could not be taken as an index of drought resistance.IAPAR9 had a higher level of POD activity,and middle level of SOD and CAT activity. |
