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.

Key words: Brazilian Upland rice IAPAR9, drought resistance, oxidase activities
