套袋对突尼斯软籽石榴果实品质的影响

摘要

为探讨套袋及套袋时间长短对突尼斯软籽石榴果实品质的影响,以10年生的突尼斯软籽石榴作为试验材料,幼果期开始套袋,观察套袋及套袋时间对其果实品质的影响.选择生长期一致的果实,在花后40 d开始套袋,分别于花后60、80、100、120 d去袋,以未套袋果实作为对照,观察其果实品质的差异,结果表明:套袋果实的综合品质均高于对照.花后100 d去袋的果实着色最好;可溶性固形物的含量最高,为16.8%(P0.05).生产上,对突尼斯软籽石榴进行套袋处理,并于果实成熟前20~30 d去袋,可以明显提高石榴的果实品质,增加生产效益.%The influences of bagging on the 40th day after flowering and bagging duration (20, 40, 60, 80 days) on the fruit quality of 10-year-old Tunisian soft-seed pomegranate were explored.The results showed that the comprehensive quality of bagged fruits was better than that of the un-bagged fruits.The fruits which were bagged during 40~100 days after flowering had the best coloring, the highest soluble solid content (16.8%, P0.05).In the production of Tunisian soft-seed pomegranate, the fruit quality and production efficiency of pomegranate can be improved obviously by bagging its fruits and by removing the bags during 20~30 days before fruit ripening.
