不同果袋对丰水梨果实品质的影响

[目的]筛选出综合效果好、适合丰水梨的果袋。[方法]以不套袋为对照,研究9种类型果袋套袋对丰水梨果实品质的影响。[结果]套袋处理可明显改善丰水梨的果皮色泽、果点密度和大小,套袋果实直径较对照平均增加2.97 mm,单果重较对照平均增加17.73 g。丰水梨套袋后果实可溶性固形物、可溶性总糖的含量及果肉硬度大多下降,固/酸比值大多提高。套袋处理的果实外观总分较对照提高1.18～2.88分,套袋对丰水梨果实内在品质的总体效果在9种果袋之间差异较大。[结论]套袋效果最佳的果袋是外袋外白内黑、内袋黑色双层纸袋,综合得分、外观总分均第1,内在品质总分第2,然后是内袋黑色、外袋灰色双层纸袋和内袋黑色、外袋灰黑色双层纸袋。

Effect of Bagging with Different Fruit Bags on Fruit Quality of Fengshui Pear

[Objective]The study aimed to screen out fruit bags that had good integrated effect and were suitable for Fengshui pear.[Method] With Fengshui pear without bagging as CK,9 types of paper bags were chosen to study the effect of fruit bagging on fruit quality of Fengshui pear.[Result]Fruit bagging could obviously improve fruit skin color,dot density and dot diameter of Fengshui pear.The diameter of bagged fruit was 2.97 mm higher than that of CK.The single fruit weight of bagged fruit weight was 17.73 g higher than that of CK averagely.The total soluble solid,total soluble sugar and flesh firmness in the bagged fruit were mostly decreased.And the ratio of solid to acid was mostly increased.The total scores of the bagged fruit appearance were 1.18-2.88 higher than that of CK.The total effect of bagging on internal quality of Fengshui pear had greater different among 9 types of fruit bags.[Conclusion] The fruit bag that get optimum bagging effect was double-layer paper bag with the outside bag being white-outer and black-inner and the inner bag being black,whose integrated score and the appearance score was the first and internal quality was the second.The second was the double-layer paper bag with inner bag being black and outside bag being grey and the double-layer paper bag with inner bag being black and outside bag being grey and black.
