Abstract: The effect of five types of fruit bag on fruit quality of Zaosu red skin pear was studied. The results showed that, brown, blue and orange bags could increase the fruit weight. After bagging, fruit shape index did not change significantly, soluble solids increased, and soluble sugar had no significant difference with the control. The treatment of brown and blue bags reduced the titratable acid content and increased the sugar acid ratio of fruits. The solid-acid ratio of fruits with brown, blue and green bags increased, and the VC content of fruits with brown, green and transparent bags was higher than that of control. The treatment of brown, blue and orange bags reduced the pericarp break force and pericarp rupture distance. After bagging, the puncture energy of pericarp decreased, the flesh firmness decreased except the treatment of transparent bags. Bagging improved the flesh fineness significantly, fruit surface smoothness and exterior qualities. By comprehensive analyzing, the recommended bags were in the following order: brown, blue, green, orange and transparent.
