Abstract: In the p rocess of seeds germination, enzyme activity was one of the most significant phenomenon. this article determined the changes of amylase, lipase, nitrate reductase and peroxidase activity during the p rocess of the three hybrid seeds germination of Lingyou 1, Zhongyou 9801, Yixiang 9303 by 3, 52dinitrosalicylic acid method, basic titration, vitro method and guaiacolmethod. The results showed that there are a significant correla2 tion between germination rate of hybrid seed and activity ofα2amylase and peroxidase
