摘要/Abstract

摘要： 研究纳米营养液采前处理在20±1℃条件下对贮藏过程中金冠苹果贮藏特性的影响。结果表明，纳米营养液采前处理可以加快果实的后熟过程，促使其转黄、转红，使乙烯高峰提早到来，同时加速芳香物质的形成和迸发。另外，纳米营养液采前处理提高了果实可滴定酸含量，降低其固酸比，从而对果实风味产生影响。结论：纳米营养液采前处理能促进苹果果实成熟衰老，对果实风味的改善有明显的作用。

Abstract: The effect of nano nutrient preharvest treatment on the storage properties of Golden Delicious Apple during storage (20±1℃) were studied in this paper. The results indicated that nano nutrient can quicken the process of fruit ripening and softening, promote the course of turning yellow and red, make ethylene peak arrive earlier, and speed up the formation and burst of aromatic substances. In addition, nano nutrient preharvest treatment increased titratable acid content, reduced its tss-acid ratio, so as to exert an influence on fruit flavor. In conclusion: nano nutrient preharvest treatment can promote the process of ripening and senescence, thus do great help for the improvement of fruit flavor to some extent.
