【摘要】 以"富士"和"嘎啦"为试材,通过套双层纸袋、无纺布袋和塑料袋3种处理,对苹果单果质量、果形指数、花色苷含量、CMYK模式指标值、果实硬度、可溶性糖、可滴定酸、可溶性固形物和维生素C含量进行了测量分析,以研究不同套袋处理对苹果品质的影响。结果表明:套袋对改善苹果外观品质效果显著,以套纸袋后蓬莱市"富士""嘎啦"以及黄陵县"嘎啦"和套塑料袋后黄陵县"富士"最为洁净、鲜亮;套袋改变了苹果单果质量,套无纺布袋和塑料袋的苹果单果质量均高于对照,而套无纺布袋的果实单果质量提高更显著;套袋改善了果实的果形指数,其中以套纸袋改善最为明显;套袋能够显著提高花色苷含量,以套纸袋后蓬莱"嘎啦"和黄陵县"嘎啦"提高最多。套袋对苹果内在品质产生不利影响,其中套双层纸袋后果实硬度、可溶性糖和可溶性固形物含量下降最少,可滴定酸含量降低最多,对苹果内在品质影响程度最低。更多还原

【Abstract】 ‘Fuji’and‘Gala’apple were used as the materials,double-layer paper bag,non-woven bag and plastic bag were used as three treatments.Apple fruit weight,fruit shape index,the content of anthocyanins,the CMYK mode index,fruit hardness,soluble sugar,titratable acid,soluble solid and vitamin C content were determined to study the influence of the different bagging treatments on apple fruit quality.The results showed that bagging had a significant effect on improving the appearance quality of apple.‘Fuji’and‘Gala’bagging double-layer paper bag in Penglai,‘Gala’bagging double-layer paper bag and‘Fuji’bagging plastic bag in Huangling were the most clean and bright.Bagging changed the apple fruit weight.Compared with contrast,non-woven bag and plastic bag could significantly improve the single fruit weight,especially non-woven bag.Baggings,especially double-layer paper bag,could improve the fruit shape index.The content of anthocyanins of‘Gala’bagging double-layer paper bag in Penglai and Huangling increased most.Bagging had a negative effect on the intrinsic quality of apple.Fruit hardness,soluble sugar and soluble solid content decreased least,titratable acid lowered most by bagging double-layer paper bag,which had the lowest impact on apple′s intrinsic quality.更多还原
