Effects of Waterlogging Stress on Antioxidant Enzymes in Rice Plants

The influence of flood disaster on rice growth and development is a research hotspot in the farmland water conservancy. In this paper, Xiushui 12 rice planted in large area in South China was used as material, The method of displacement and submergence of potted plants, Study on Effects of waterlogging stress on antioxidant enzymes in rice plants, Clearing the depth and diachronic of flooding in different growing stages of rice, Provide theoretical references for regional paddy field drainage and farmland water conservancy construction. The results show that the content of antioxidant enzymes in rice plants is higher than that in early growth stages, indicating that proper water stress can increase the content of antioxidant enzymes., rice at different growth stages showed a certain ability to resist flooding stress, but the tolerance to flooding and sensitivity were different, The S1 stage is the strongest and the S2 stage is the most sensitive. The optimal flooding depth and duration of rice at three stages of S1, S2 and S3 were plant height 3/4 (W2), plant height 1/2 (W1), plant height 3/4 (W2) and 5d (T2)., 3d (T1), 3d (T1).
