胁迫温度短期冲击对松毛虫赤眼蜂谷胱甘肽硫转移酶活性的影响

摘要

Trichogramma dendrolimi was taken as objects to measure specific activity of glutathione S -transferase under different temperature conditions , results indicated that the lowest specific activity of glutathione S -transferase was 6.80 ± 4.7 that temperature reached at 15℃, whereas the highest specific activity was 98.22 ±1.76 that temperature reached at 35℃.When temperature reached at 25℃, the value was 32.49 ±2.60.Specific activity of glutathione S -transferase showed significant differences among the three different temperature conditions , and the specific activity increased with the rise of temperature .%以松毛虫赤眼蜂为对象，对其不同温度条件下的谷胱甘肽硫转移酶比活力进行测定，结果表明：在15℃处理条件下，谷胱甘肽硫转移酶的比活力最低，为6．80±4．71；在35℃处理条件下最高，为98．22±1．76；25℃处理介于两者之间，为32．49±2．60；3种温度条件下的谷胱甘肽硫转移酶比活力存在显著差异（P ＜0．05），且随着温度的升高比活力显著上升。
