Using nonwoven bag, white paper bag, kraft paper bag separately covered the ‘Pollock’ avocados after the second physiological drop, we measured regularly the changes of internal and external quality indexes such as fruit color parameters, fruit shape index, and the content of pericarp pigment, soluble sugar, soluble solids, Vc, fat, soluble protein. The purpose is that studies on the effect of different bagging materials on the growth and development process of avocado fruit in the appearance quality and internal quality. It aims to provide a theoretical basis for high quality cultivation of avocado. The results showed that: (1) the three kinds of bagging materials could significantly promote the growth of avocado fruit.They significantly increased the single fruit weight of mature fruit, but there is not significant effect on the growth and development and maturity on avocados. (2) Nonwoven bags could significantly improve the fruit shape index of avocados, while the other two bagging materials did not. Although the kraft paper bag could significantly increase the brightness of fruit, but would make the pericarp turn yellow. White paper bags and nonwoven bags could increase fruit brightness, but they were not significantly different from the control group. (3) Nonwoven bags and paper bag processing could significantly improve carotenoids and chlorophyll in pericarp, soluble sugar, soluble solids, VC, fat and soluble protein contents in pulp of avocado. Kraft paper bag also could significantly improve soluble solids, soluble sugar, soluble protein and fat contents in pulp of avocado, while reducing the chlorophyll content in pericarp and Vc content in pulp, inhibition of carotenoid synthesis and accumulation in pericarp. (4) All bagging materials could also change the avocado pericarp thickness. The kraft paper bags could significantly improve the pericarp thickness, while nonwoven bags and white paper bags have reduced the pericarp thickness. All bags had no significant effect on pulps density. (5) According to the comprehensive analysis of membership function method, the results indicated that nonwoven fabric bags are optimum bagging materials, and the white paper bags are the second. These results greatly enriched the suitable bagging materials can significantly promote the avocados growth and development, improving the appearance quality and internal quality of avocado fruit. In this experiment, the effect of nonwoven bag bagging is the best.
