不同套袋处理对‘岳苹’果实品质及着色的影响

Effects of Bagging Treatments on Fruit Quality and Coloration of ‘Yueping' Apple Variety

为探讨‘岳苹’苹果的适宜果袋及摘袋后果皮色素含量的变化规律,确定摘袋后的适宜采收时间,对其设定3种套袋处理,并对不同处理果实内含物、糖、酸和果皮色素的含量进行测定。结果表明：套纸袋使‘岳苹’果实的硬度和果皮花青苷的含量分别提高7.7%和30.9%,促进果实着色,提高果实外观品质,但降低了‘岳苹’果实的风味,使果糖、蔗糖和总糖的含量分别降低了14.2%、59.7%和19.2%;套塑膜袋使‘岳苹’果实的硬度及果皮花青苷的含量分别降低了6.1%、10.0%和36.4%、35.3%;套塑膜袋摘袋使果实果糖和总糖的含量分别提高11.6%和6.8%;同时确定了‘岳苹’果实摘袋后采收的最佳时间为9~11天。

The changes of fruit peel pigment after bag removal and the suitable bags of the ＇Yueping＇ apple fruit were studied in order to determine suitably time of harvest after bag removal. Setting for the 3 treatments of bagging, the content of different treatments of inner substance.s, sugars, acids and fruit peel pigments were tested with ＇Yueping＇ apple as material. The results indicated ＇that the paper bags increased the content of ＇Yueping＇ fruit firmness 7.7% and the peel anthocyanin 30.9%, promoted fruit coloring, improved fruit appearance quality, but decreased the relish of ＇Yueping＇ fruit and reduced fructose 14.2%, sucrose 59.7%, and total sugar 19.2%. The plastic film bags reduced the content of ＇Yueping＇ fruit hardness 6.1%, 10.0% and the peel anthocyanin 36.4%, 35.3%. The plastic film bags removing treatment improved the content of fruit fructose 11.6% and total sugar 6.8%; at the same time to determine the best time of ＇Yueping＇ fruit harvest after bag removal were 9-11 days.
