两种诱雄剂对黄瓜植株保护酶类活性的影响

Effect of Two Male-Inducing Reagents on Protective Enzyme Activity in Cucumber

通过测定AgNO_3和Ag_2S_2O_3两种诱雄剂对黄瓜雌性系h154,151和普通系h002植株保护酶类活性的影响,结果表明,茎尖中的POD,CAT活性较对照都有所升高,处理48 h时酶活性达到最高,POD活性增幅分别为164-4%,133.5%,241.5%和23.1%,16.5%,57.2%;CAT活性增幅分别为91.3%,95.7%,113.5%和69.6%,64.3%,82.4%。AgNO_3处理黄瓜幼苗后SOD活性先下降,后升高,处理120 h时,SOD活性达到最高,增幅分别为75.3%,65.2%,30.7%和27.2%,36.9%,16.2%。

The results showed that the activity of peroxidase and catalase was increased of shoot tips in gynocious lines h154,h151 and the normal line h002 by the treatments with AgNO3 and Ag2S2O3. The maximum increment of peroxidase were 164.4%, 133.5%, 241.5% and 23.1%, 16.5%, 57.2% after 48 h by treated, the maximum increment of eatalase were 91.3%, 95.7%, 113.5% and 69.6%, 64.3%, 82.4% after 48 h by treated. The superoxide dismutase activity was decreased first and then increased by AgNO3 treatment, the maximum increment of superoxide dismutase were 75.3%, 65.2%, 30.7% and 27.2%, 36.9%, 16.2% after 120 h by treated.
