摘要
以4个白三叶品种为试材,采用温室盆栽,人工梯度控水,结合实验室技术,研究了干旱胁迫下及复水后对白三叶品种叶片保护酶活性的影响。结果表明:干旱胁迫后,4个品种的SOD、POD和CAT活性均随着干旱胁迫时间的延长,呈现先升高后降低的变化趋势;抗旱性强的小黑龙具有较高的SOD、POD和CAT活性。复水后4个品种的SOD、POD和CAT活性,有不同程度的恢复,其中抗旱性强的小黑龙恢复较好。
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 dover 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.
