| 摘 要： | 本文研究了4种诱抗剂防治豌豆白粉病的效果及其诱导豌豆叶片防御酶活性变化。结果表明,用不同诱抗剂进行诱导处理后第7天,对豌豆白粉病防效为16.25%~52.18%,效果最好的处理为0.1%S-诱抗素,平均防效为52.18%,处理后第10天,防效上升到20.59%~56.43%,效果最好的仍为0.1%S-诱抗素;喷施诱抗剂后增产效果明显,不同处理平均增产幅度在0.77%~12.54%之间;诱导后显著提高了抗性相关防御酶POD活性,其中0.1%S-诱抗素处理POD酶活性最高,但却降低了CAT酶活性。

| Abstract: | Effect of four inducers on pea powdery mildew control and defensive enzymes activity was investigated in this paper. The results showed that the average control efficacy was between 16.25% and 52.18% at the seventh day after treatment,and the best treatment was 0.1% S-ABA with control efficacy of 52.18%. At the tenth day after treatment, the control efficacy increased and reached to 20.59%-56.43%,and 0.1% S-ABA was still the best treatment. After spraying inducers,the yield increased obviously by 0.77%-12.54%. The activity of POD, one of the defense enzyme related disease resistance, was significantly improved in induced leaves, but the CAT activity in induced leaves was reduced. POD activity of 0.1% S-ABA was the highest. |
