摘　　要：为了探究大丽花轮枝孢激活蛋白(Verticilliam dahliae Allergen Asp f2-like,VdAL)干粉制剂对黄瓜商品苗贮藏质量的影响,以黄瓜幼苗为试验材料,在育苗期进行了3次不同浓度叶面喷施处理,分析贮藏前与贮藏4 d后黄瓜幼苗质量相关指标以及定植后3~6 d恢复生长指标。结果表明:1.25 g·L^(-1)大丽花轮枝孢激活蛋白处理可以显著增强黄瓜幼苗的耐贮运性,与其他处理相比,该处理浓度贮藏过程中叶绿素含量稳定,定植后恢复生长快,表明育苗期叶面喷施适宜浓度的大丽花轮枝孢激活蛋白,有利于提高黄瓜商品苗的贮藏质量。In order to explore the effects of Verticillium dahiliae allergen Asp f2-1ike （ VdAL ） on storage quality of commercial cucumber seedling, this paper takes cucumber seedlings as test material, and conducts 3 spraying processing with different concentrations, and analyzes the quality-related indicators of cucumber seedlings before storage and 4 days after storage and also the recovery growth indicators 3-6 days after planting of seedlings. The results show that 1.25 g .L-1 VdAL treatment can significantly enhance the tolerance of cucumber seedlings to storage and transportation. Compared with other treatments, the concentration of this treatment makes the cucumber seedlings have very stable chlorophyll contents during storage period, and have fast growth after planting. These facts suggest that foliage spraying with suitable VdAL concentration is helpful for upgrading the storage quality of commercial eucumber seedlings.
