Abstract: The experiment was carried out to study the effect on fruit quality after bagging on Newhall navel orange, with different types of paper bag and at different stages to remove the bags. The result suggested that the lightness and yellowness of fruit increased significantly, while the redness was significantly reduced. Individual fruit weight tended to be decreased, and the rind thickness had no significant difference, total soluble solid and TSS/TA were improved after bagging, total acid was reduced after bagging, but not all treatments had significant difference. Double-layer bag is suitable to Newhall navel orange and the optimal time for Newhall navel orange to remove bags is one month before harvest.
