Effect of Drought and Water Recovers on Protective Enzymes Activities of 4 White Clovers

4 cultivars white clover were used in this experiment.They were planted in pots in a greenhouse and the atmospheric humidity was artificially controlled.Protecting Enzyme Activity of 4 Cultivars white clover under drought stress and water recovers.The results indicated that under drought stress,SOD,POD,CAT activity of 4 cultivars with the drought treatment time prolonged showed first increasing then decreasing.Drought resistance of the Mini Black Dragon have a high SOD,POD and CAT activity.After water again,SOD,POD,CAT activity of the cultivars intracellular in varying degrees of recovery,which Mini Black Dragon recover better.
