Abstract:
Taking Medicago sativa ssp.,‘Vitoria’ alfalfa and Medicago sativa cv.as materials，effects of Se stress on the activities of antioxidant enzymes and the contents of soluble protein and MDA in three Medicageo staival L.were studied with soil culture.The results indicated that the activities of SOD，APX，POD and CAT and the content of soluble protein in the leaves of three Medicageo staival L.was increased under 100 μmol?L-1 Se.After exposure to 900 μmol?L-1 Se，Se stress markedly increased the activities of SOD and APX，and the contents of soluble protein and MDA in the leaves of three Medicageo staival L..However，Se stress markedly decreased the activities of CAT and POD in the leaves of three Medicageo staival L..Under different levels of Se stress，Medicago sativa ssp.had the highest activities of SOD，CAT，APX and POD，compared with other species.Above results suggested that the order of antioxidant capacity of the three Medicageo staival L.species was Medicago sativa ssp.,‘Vitoria’ alfalfa and Medicago sativa cv.
