Effect of Bagging on Fruit Quality of Late-ripening Peach Cultivar Xiahui 8

The effect of different bagging treatments on the fruit quality of peach cultivar Xiahui 8 was studied by using no bagging as the control.The results showed that bagging treatment could change the pericarpial coloration,raise sugar-acid ratio,and improve fruit flavor.Single-layer bag or double-layer bag with yellow outside and black inside could increase the red level of pericarp if the bags were removed before harvest.In the bagging treatment with single-layer yellow bags,the single-fruit weight was the highest,but both red color and pericarp anthocyanin content of fruits were significantly lower than those in the control.In the bagging treatment with single-layer white bags,the single-fruit weight,soluble solid content,sugar-acid ratio,red saturability,and chroma of fruits were significantly higher than those in the control;the hardness with pericarp,hardness without pericarp,brightness value,hue angle,and a*/ b*value were not significantly different from those in the control;this treatment obtained better comprehensive fruit quality.In the bagging treatments with single-layer bags or double-layer bags whose color was yellow outside and black inside,the single-fruit weight,pericarpial coloration,pericarp anthocyanin content and sugar-acid ratio of fruits were higher than those in the control,but the soluble solid content and hardness of fruits were not significantly different from those in the control;the comprehensive quality of fruits in these two bagging treatments(especially the bagging treatment with double-layer bags) was better than that in the control.
