| 摘 要： | 以"新泰密刺"黄瓜为试材,选用5、10、20、30、40mg/L的脱落酸(ABA)处理黄瓜幼苗,研究外源ABA对黄瓜抗霜霉病的影响。结果表明:适当浓度ABA处理可诱导黄瓜抗霜霉病,降低病情指数,诱导叶片防御酶POD、SOD、PAL、PPO活性升高。其中10mg/L浓度处理表现效果最好;诱导抗性可持续8d以上,第4天防御酶活性均高于第8天。

| Abstract: | The induced resistance to Pseudoperonospora cubensis was conducted on cucumber treated with different concentrations of exogenous ABA.The results showed the treatments with suitable concentrations of exogenous ABA reduced the disease index,and increased protective enzyme activities(POD,SOD,PAL,PPO).The treatment of 10 mg/L ABA had the best effect on the induced resistance which could maintain more than 8 days,and the effect of the forth day was better than that of the eighth day. |
