摘　　要： 套袋是提高苹果果实着色的关键技术,但同时也带来了果实内在品质下降,风味变淡等问题。为探索一种更为高效省力,安全环保,逐步替代苹果套袋的新技术,该研究以自主研发的2种苹果专用品质改良剂为试材,测定其对中早熟苹果果实品质各指标的影响,旨在为优质苹果的生产提供一种新方法和新思路。结果表明:2种品质改良剂均能有效促进中晚熟苹果果皮着色,显著提高果实糖、酸度,增加维生素C含量;2种品质改良剂在"玉华早富"上应用单果重、果形指数、可溶性固形物含量、硬度及Ca含量也都有显著增加,同时提高了果实内外在品质;综上所述,2种品质改良剂在中熟品种"玉华早富"上应用效果更好,能够同时改善果实风味、营养及贮藏品质,促进果实着色。 Bagging is the key technology to improve apple fruit coloring,whereas,it can bring the fruit internal quality and the flavor reduced.To explore a new method to replace the bagging,which is more efficient and energy saving,safety and environmental protection,the experiment was conducted taking the two fruit quality improvers independently researched and developed as material,so as to test the effect of different improvers on intrinsic and appearance of‘Yuhua Zaofu＇and‘Changfu No.2＇apples.The results showed that both two kinds of quality improver could effectively promote the varieties of apple coloring,increase the content of vitamin C and sugar acid ratio significantly.In addition the fruit weight,shape index,soluble solid content,the fruit hardness and calcium content of‘Yuhua Zaofu＇increased significantly.In conclusion,two kinds of quality improver showed significant improve on the fruit flavor,storage quality and apple nutrition,and thus improve the coloring of‘Yuhua Zaofu＇apple.
