Abstract: 【Objective】 The effects of 5 kinds of plant immune inducers on the photosynthetic and physiological changes and disease resistance of the cucumber were determined, and the scientific basis was provided for the application of the plant immune inducers to the cucumber.【Method】 The effects of 5 kinds of plant immune inducers on the physiological and physiological changes, disease resistance and the activity of the defense enzymes were determined by pot experiment.【Result】 Nashi778 inducer could increase chlorophyll content and advance flowering stage of cucumber plants, and the yield was 3.5 times higher than that of the control.The photosynthetic performance of cucumber plants was improved by plant immune inducer protein, and the control effect of cucumber powdery mildew was 99.07%.The protein immune preparation increased the activities of POD and CAT, which was 1.8 and 2.5 times higher than the CK value, and the control effect on cucumber powdery mildew was 70.68%.【Conclusion】 The plant immune-induced protein and the Nashi778 inducer can obviously promote the yield of the cucumber, and can improve the disease resistance of the cucumber plant to the powdery mildew, and is suitable for application in the production of the cucumber.

Key words: plant immune inducer; cucumber; photosynthetic characteristics; chlorophyll fluorescence parameter; induced disease resistance; defense-related enzymes

摘要: 【目的】 研究5种植物免疫诱导剂对黄瓜光合生理变化和抗病性的影响,为植物免疫诱导剂在黄瓜上应用提供科学依据。【方法】 采用盆栽试验,测定5种植物免疫诱导剂对黄瓜光合生理变化、抗病性和防御酶活性的影响。【结果】 那氏齐齐发诱导剂可提高叶绿素含量、促进黄瓜植株花期提前,产量相比对照提高3.5倍;植物免疫诱抗蛋白提高黄瓜植株光合性能,防治黄瓜白粉病效果达99.07%;蛋白免疫制剂提高了POD和CAT活性,是CK值的1.8和2.5倍,对黄瓜白粉病的防效为70.68%。【结论】 植物免疫诱抗蛋白和那氏齐齐发诱导剂可显著促进黄瓜增产且可提高黄瓜植株对白粉病抗病性,适宜在黄瓜生产中应用。
