摘要 采用外红里黑复合袋处理、浅黄色单层袋处理、深黄色单层袋处理、红色单层袋处理4种果袋对“金艳”猕猴桃进行套袋处理,探究不同颜色、类型的果袋对猕猴桃果实外观品质、内在品质和常温下贮藏性的影响。结果表明,套袋处理能有效提高果实外观品质,增加商品果率,但果实采摘期和软熟期的内在品质均有不同程度下降,仅红色单层袋处理的果实表现优于对照,表现出高干物质和可溶性固形物含量、更浓郁的风味、较黄的果肉以及超长的贮藏期(90 d)等特点,因此建议将红色单层袋应用于“金艳”猕猴桃的实际生产中。

Abstract The four treatments of outer red and inner black composite bag treatment, pale yellow single paper bag treatment, deep yellow single paper bag treatment, red single paper bag treatment were used in Jinyan kiwifruit bagging, to study the effects of different colors and types of fruit bags on fruit appearance, internal quality and storage characteristics at room temperature. The results showed that using bagging treatment on Jinyan kiwifruit could effectively improve the appearance quality of fruits and increase the ratio of commodity fruit, but the internal quality of fruits in the harvest period and the soft ripening period decreased in varied degrees. Only the fruits treated with red single paper bag performed better than the control group, showing higher dry matter content and soluble solid content, stronger flavor, yellow flesh and extra longer storage period (90 d), etc. Thus, it is suggested that the red single paper bag treatment could be applied to Jinyan kiwifruit production.
