不同果袋对砀山酥梨果实品质的影响

选用了18种不同果袋对砀山酥梨果实进行套袋试验,结果表明,套袋后砀山酥梨果实的硬度、可滴定酸含量比对照显著增大;可溶性固形物、可溶性总糖含量以及单果重均显著降低,平均比对照分别降低10.57%,11.74%,27.96%;套袋梨果的石细胞含量比对照降低10%～52.7%;套三层果袋的果实内在品质比套双层果袋和单层果袋果实的内在品质降低更显著;套袋对果实光洁度和果点等外观品质明显改善,三层果袋和双层果袋效果显著优于单层果袋。

Effect of bagging with different types of bags on fruit quality of Dangshansu pear cultivar

Eighteen different types of bags were chosen to study the effect of fruit bagging on Dangshansu pear cultivar fruit quality. The results showed that the fruit firmness and the content of titratable acidity in bagged fruit were higher than CK, and TSS (total soluble solid), total soluble sugars, fruit weight on average were decreased by 10.57%?11.74% and 27.96%, respectively. The sclereid content was markedly affected by fruit bagging, decreased by 10% to 52.7% than CK;The internal quality of Dangshansu pear fruit bagged with three-layer bags was much reduced than that of Dangshansu pear fruit bagged with two-layer and single-layer bags. The bagged fruit skin gloss was better than CK and the fruit spots were obviously less than CK. The effect of 2-layer and 3-layer bag was better than the single-layer bags. But the cost of the 3-layer bag was higher than that of the 2- layer bag, so the 2-layer fruit bag is the best choice.
