摘　　要：以‘红阳’猕猴桃为试材,采用4种不同类型果袋(复合袋、黄袋、黑袋、白袋)套袋处理,研究了各处理果实的单果质量、纵横径、果肉糖酸含量、果肉色素含量等指标及其变化规律,以期为高品质生产‘红阳’猕猴桃提供参考依据。结果表明:复合袋处理的内果皮花色苷含量、可溶性糖含量在采收期和后熟期显著高于其它各处理,采收期的叶绿素含量和可滴定酸含量显著低于其它各处理,果肉红色更为凸显;白袋处理的内果皮花色苷含量较低,采收时可溶性固形物、可滴定酸含量和中果皮的叶绿素含量较高,果肉颜色偏绿;黑袋处理在后熟时中果皮可溶性糖含量较高;黄袋处理的中果皮和内果皮可溶性糖含量均较低;各处理在采收期的单果质量、纵径、横径无显著相关性,在类黄酮含量方面无显著规律;综上,套3层复合袋处理的果实叶绿素含量降低,果肉呈现黄绿色,花色苷含量提高,中心红色更为凸显,提高了果实可溶性糖含量和降低了可滴定酸含量,果实综合品质提升。Taking ‘Hongyang’ kiwifruit as test material, four different types of fruit bags(composite bag, yellow bag, black bag and white bag) were used to study the single fruit weight, longitudinal and transverse diameter, pulp sugar and acid content and pulp pigment content, and so on.And it also included the law of change with the intent to provide reference for high-quality production of ‘Hongyang’ kiwifruit.The results showed that the anthocyanin content and soluble sugar content of inner pericarp treated with composite bag were significantly higher than those of other treatments at harvest and post ripening, and the chlorophyll content and titratable acid content at harvest were significantly lower than those of other treatments, and the sarcocarp was the reddest.The anthocyanin content of inner pericarp with white bag was lower, at harvest time the soluble solids content, titratable acid content and chlorophyll content of mesocarp were higher, and the sarcocarp color was green.The content of soluble sugar in mesocarp was higher in black bag treatment at after-ripening.The soluble sugar content of mesocarp and endocarp treated with yellow bag was lower.There was no significant correlation between the single fruit weight, longitudinal diameter and transverse diameter of each treatment at the harvest time.There was no significant law in the content of flavonoids in each treatment.In conclusion, the treat of composite bag had the lower chlorophyll content and higher anthocyanin content, its sarcocarp showed yellowish green, also the central red was more prominent.And the treat increased the soluble sugar content and reduced the titratable acid content of fruit, so improved the comprehensive quality of fruit.
