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.
