摘　　要：[目的]研究叶面喷锌对粉红亚都蜜葡萄几个生理指标和果实品质的影响,以指导葡萄生产。[方法]以2001年引进的粉红亚都蜜葡萄为试材,研究了生长季节叶面喷施2.5、5.0、7.5 mg/L ZnSO4.7H2O,对葡萄叶片叶绿素、蛋白质、可溶性糖含量等生理指标及果实VC含量、可滴定酸含量、可溶性固形物含量、果形指数、果皮厚度、果刷长度等品质指标的影响。[结果]不同浓度喷锌以5.0～7.5mg/L的效果较好,可使粉红亚都蜜葡萄叶片叶绿素、可溶性糖、蛋白质和果实VC、可溶性固形物含量明显提高,果皮变厚,果刷变长,且随喷锌次数的增加效果愈明显;而果形指数和可滴定酸含量随喷锌次数的增加明显降低。[结论]5.0～7.5 mg/L浓度锌叶面喷至少2～3次,可明显提高葡萄的光合效率,改善其风味、营养及耐贮运品质,建议在生产中推广应用。[Objective] The purpose was to study the effects of foliar spraying zinc on some physiological indices and quality of Fenhongyadumi gape,and to guide its production.[Method] The experiment was carried out to study the effect of foliar spraying 2.5,5.0,7.5 mg/L ZnSO4·7H2O on some physiological indices,such as chlorophyll content,protein content,soluble carbohydrate content,and quality indexes,such as VC content,titratable acid content,total soluble solid content,fruit shape index,fruit peel thickness,fruit brushes length and so on,using Fenghongyadoumi grape introduced in 2001 as experimental material.[Result] The results showed that 5.0-7.5 mg/L zinc could increase chlorophyll content,soluble sugar content,soluble protein content,and VC content,total soluble solid content distinctly,and its fruit peel became thick and fruit brush became long,and this increase effect was more distinct with spraying zinc times increased;While the fruit shape index and the contents of titratable acid reduced distinctly with spraying zinc times increased.[Conclusion] When the concentration of Zinc is 5.0-7.5 mg/L,and at least 2-3 times foliar spraying,the photosynthetic efficiency increases and flavor,nutrition,storage and transportation quality of grape improve significantly.
