Effect of Different Fruit Nursery Bag on the Fruit Quality and Antioxidant Enzyme Activity of Zizyphus mauritiana Lam.Misi
The effects of fruit nursery bag on the fruit quality and antioxidant enzyme activities of zizyphus mauritiana lam.misi.were studied with four different types of bags,including one-layer colorless transparent plastic film bag,one-layer white un-woven cloth bag,one-layer white paper bag,and two-layer yellow-out-darkin paper bag.The results showed that fruit nursery bag could improve the external quality and enhance the activities of antioxidant enzymes such as peroxidase(POD) and catalase(CAT).At the same time,fruit nursery bag affected the internal quality to some extent and decreased the fruit taste.After bagging with 4 types of fruit bags,only the colorless transparent film bag could significantly improve the fruit weight(22.1% higher than the control),while the other three types of fruit nursery bag inhibited fruit growth to some extent,which resulting to fruit weight decreased.In addition,one-layer colorless transparent plastic film bag could produce fruit with better internal quality than the other three types of bags.Only soluble solids and titratable acidity decreased obviously,while total soluble sugar almost showed no significant effect and Vitamin C content increased slightly.In comprehensive consideration,one-layer colorless transparent plastic film bag should be recommended according to the fruit quality and marketability of zizyphus mauritiana lam.misi.
