摘要
以套袋金冠苹果为试材,研究了7个不同时期除袋处理对金冠果面光洁度、着色指数、果皮花色素、叶绿素、类胡萝卜素含量及果实可溶性固形物、总糖、维生素C含量等内外在品质指标的影响。结果表明:套袋金冠采前10 d除袋,待统一采收时果实着红色,果皮嫩,果点小,果实着色指数最大;果皮叶绿素含量最低,对人体有保健功能的花色素含量最高;果实总糖含量、可溶性固形物含量均达到最高,果实的内、外在品质与果皮花色素含量均达到最理想状态,为宁夏金冠产区的最佳除袋期。
Taking bagged Golden Delicious as material,we studied the effects of seven different debagging dates on the fruit inner quality indexes（ the contents of anthocyanin,chlorophyll and carotenoid in pericarp,as well as the contents of soluble solids,total sugar and ascorbic acid in fruit） and appearance quality indexes（ fruit surface finish and coloration index）. The results indicated that debagging on the 10 th day before harvest of bagged Golden Delicious in Ningxia area had the best effects： when the fruits were uniformly harvested,their pericarps were red and tender with small dot; the fruits had maximum coloration index; their pericarps had the lowest chlorophyll content and the highest anthocyanin content,which is good for human health; the contents of both total sugar and soluble solids in fruits were the highest.
