不同果袋对中油4号油桃品质的影响

Effect of Different Bags on the Quality of Zhongyou 4 Nectarine

为筛选油桃适合的果袋,以中油4号油桃品种为试验材料,研究了不同果袋对油桃果实品质的影响。结果表明:与不套袋相比,套袋处理显著降低了病虫果率和果锈指数,增加了油桃果形指数和单果重。4种果袋处理中,单层白色果袋处理的果形指数和单果重显著高于其它3种纸袋,而果实可溶性固形物含量、可溶性糖含量、可滴定酸含量、维生素C含量和去皮硬度4种果袋处理间差异不显著。因此,选用单层白色纸袋对于辽宁营口地区油桃生产是一种较好的方法。

In order to screen suitable fruit bags,the nectarine variety Zhongyou 4 was used as material to study the effect of different bags on fruit quality.The results showed that disease and pest rates,fruit rust index of nectarine with four bagging treatments were decreased significantly,while fruit shape index and single fruit weight were increased,compared to control.The fruit shape index and single fruit weight of nectarine with white double-layer bag were significantly higher than other three paper bags.As to the inner quality,such as soluble solids,soluble sugar,titrable acid,Vitamin C contents and flesh firmness,there was no significant difference between four kinds of fruit bags.Therefore,white double-layer bag was suitable for the high quality nectarine production in Yingkou area of Liaoning province.
