摘　　要：本研究以8~10年生苹果品种“寒富”作为试材,研究不同浓度植物免疫诱抗剂ZNC(宛氏拟青霉提取物)对苹果腐烂病的防治效果。试验共设4个处理,ZNC浓度分别是5 ng·mL^(-1)(T1)、15 ng·mL^(-1)(T2)和30 ng·mL^(-1)(T3),以清水为对照(CK)。通过对生长期苹果树的茎叶进行不同浓度的ZNC喷雾处理和室内病菌培养试验,探究不同浓度ZNC对苹果叶片光合特性、可溶性蛋白质含量、细胞膜渗透率、丙二醛含量、POD活性等生理指标以及对病菌菌丝生长活性的影响。试验结果表明植物免疫诱抗剂ZNC对苹果腐烂病有防治效果,在生产中可以施用5 ng·mL^(-1)ZNC来防治苹果腐烂病。In this study,the 8~10 years old apple variety"Cold Fortune"was employed as the test material,the objective of the experiment was to investigate the impact of varying concentrations of the plant immunity-inducing antagonist ZNC(extract of Penicillium wannabe)on the prevention and management of apple rot disease.Four treatments were established in the experiment,comprising ZNC concentrations of 5 ng·mL^(-1)(T1),15 ng·mL^(-1)(T2)and 30 ng·mL^(-1)(T3),with clear water serving as the control(CK).The impact of varying concentrations of ZNC on physiological indices,including photosynthetic characteristics,soluble protein content,cell membrane permeability,malondialdehyde content,POD activity and the growth activity of mycelium in pathogens,was examined through the application of distinct concentrations of ZNC to the stems and leaves of apple trees during the growth period,coupled with an indoor pathogen culture test.The findings demonstrated that the plant immune enhancer ZNC was efficacious in managing apple rot disease.The application of 5 ng·mL^(-1)ZNC proved effective in controlling apple rot disease in production.
