摘要： Effects of sodium selenite treatments on rice were investigated using two known cultivars Xiangyaxiangzhan and Meixiangzhan2 cultivated at two sites of Guangdong Province, China Sodium selenite solutions at 10 (Se1), 30 (Se2) and 50 (Se3) mu mol.L-1 were sprinkled to the rupturing-stage rice separately, with a control set with double distilled water instead. For Xiangyaxiangzhan, comparing with control, 6.91, 24.81 and 25.00% higher SOD, POD and CAT activity were recorded in Se1. For Meixiangzhan2, 2.10, 9.44 and 10.00% higher SOD, POD and CAT activity were recorded in Se1. Moreover, high-concentration sodium selenite (Se3) depressed the antioxidant enzyme activities and caused MDA over-production in Xiangyaxiangzhan. In conclusion, sodium selenite low-concentration applications could be an exogenous regulator to improve rice oxidation resistance in rice production.
