摘要： 在人工控水条件下，研究了两个不同抗旱花生品种苗期水分胁迫处理对其抗衰老酶活性日变化的影响。结果表明：鲁花11超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性日变化为双峰曲线，11:30达到第一个活性高峰，15:30达到第二个活性高峰。农大818 SOD活性13:30达到活高峰，P0D、CAT活性日变化为双峰曲线，11:30达到第一个高峰，15:30达到第二个高峰。农大818 SOD、POD活性显著高于鲁花11，中度水分胁迫处理活性显著高于轻度水分胁迫处理。苗期水分胁迫处理明显提高了两品种的抗衰老酶活性，农大818抗水分胁迫能力强于鲁花11。

Abstract: The effects of drought at seedling stage on anti-ageing enzymes acivities in peanut were studied under water control condition. The results shouwed that daily change of superoxide dismutase (SOD), peroxidase (POD) and catlase (CAT) activity of Luhua 11 was a double peak curve respectively, and reach the first peak at 11:30 and came to the second peak at 15:30. SOD activity of Nongda 818 came to the peak at 13:30, but daily change of POD and CAT activity was a double peak curve respectively, and reached the first peak at 11:30 and the second peak at 15:30. SOD、POD activity of Nongda 818 was much higher than that of Luhua 11. Dought in during seedling stage enhanced anti-ageing enzyme activity in two peanut cultivars, and anti-ageing enzyme activity in Nongda 818 leaves was higher than that in Luhua 11 leaves.
