Bagging thefruits on the trees of litchi,Chinensis Sonn.cv.Jizuili,was studied to determine its effect on quality ofthe fruits.Single-fruit and entire-panicle coverages with bags were compared with bare fruits for the experiment.The single-fruit bagging was found to result in improved pericarp coloration,early color development,and increased fruit weight and sizeover the other treatments.The bagging did not cause any major changes on the chemical makeup of the fruits,except a significantly increased content of soluble solids,a slightly increased titratable acid as well as reduced soluble sugars and vitamin C.The resultwould be used ina feasibility study onthe mechanization of litchi fruit-bagging at the plantations.%以不套袋为对照,研究单果套袋和整穗套袋对鸡嘴荔果实若干品质的影响.结果表明,单果套袋在改善鸡嘴荔果皮色泽,促进提前转色,增加单果重和果个大小方面均优于整穗套袋和不套袋,而在果实内在品质方面,除显著性增加可溶性固形物含量外,单果套袋却增加了采收期果实可滴定酸含量,降低了可溶性糖含量和维生素C含量,但与其他处理并无显著性差异.
