摘　　要：【目的】探讨植物免疫蛋白对草莓光合特性及果实品质、产量的影响,为草莓高效优质栽培提供技术支持。【方法】以‘章姬’草莓为试验材料,采用田间小区试验,施用1 000倍液植物免疫蛋白处理,以清水为对照(CK),进行田间栽培肥效对比试验。【结果】增施植物免疫蛋白可增加整个生育期草莓的叶绿素相对含量,显著提高草莓净光合速率和产量(P<0.05),改善草莓果实品质。与对照相比,施用普绿通植物免疫蛋白使草莓在营养生长期、开花坐果期、盛果期的叶绿素相对含量分别增加1.06%、3.71%、2.40%,并且在开花坐果期达到显著差异(P<0.05);草莓净光合速率和产量分别提高15.56%和24.45%。草莓果实的横径、纵径分别增加5.62%和3.40%,硬度、可溶性固形物和维生素C含量分别增加11.7%、5.49%、3.89%,其中可溶性固形物含量变化达到显著差异(P<0.05)。【结论】植物免疫蛋白能有效促进草莓生长,改善草莓品质和提高产量,可在草莓生产上推广应用。[Purpose]In order to provide technical support for high yield and good quality cultivation, the effects of plant immune proteins on the photosynthesis characteristics, fruit quality and yield of strawberry were studied.[Method]Taking ‘Akihime＇ strawberry as experimental materials, the field plot experiment was conducted to study the fertilizer effect of applying 1 000 times diluents of plant immune proteins, with spraying water as control（CK）.[Result]Applying plant immune proteins increased relative chlorophyll content of strawberries and significantly prompted the net photosynthetic rate and yield（P〈0.05）, meanwhile, improved the fruit quality of strawberry. Compared with the control, the relative chlorophyll content of strawberries increased by 1.06% , 3.71% and 2.40% , during the vegetative, flowering-fruit bearing and full fruit period, the net photosynthetic rate and yield significantly improved by 15.56% and 24.45% （P〈0.05）, respectively. The horizontal diameter and vertical diameter of strawberry fruit were significantly increased by 5.62% and 3.40% , the hardness and content of soluble solid and vitamin C increased by 11.7% , 5.49% and 3.89% , respectively, by applying plant immune proteins, and there were significant difference（P〈0.05） in soluble solid content.[Conclusion]Applying plant immune protein can improve the fruit quality of strawberry and increase the yield, and be popularized and applied in strawberry production.
