摘　　要：为了研究不同激素对苹果果实糖组分积累与品质的影响,以阿克苏富士苹果为研究对象,设置IAA、GA3和6-BA三种激素处理,采用热滴定法和比色法测定各糖分含量,对数据进行相关性和显著性分析。研究表明:阿克苏富士苹果成熟期果实中的糖组分的积累量排序表现为:总糖>还原糖>果糖>葡萄糖>蔗糖,其中果糖占总糖的比例最大;在不同激素处理下,IAA500 mg/L、GA3 250 mg/L和6-BA250 mg/L处理对糖分的积累作用最显著,具有较好的品质;阿克苏富士苹果果实品质综合评价可由甜度值来判断,其中果糖对甜度值的贡献最大,果糖对总糖的影响也最显著。In order to study the effects of different hormones on sugar components accumulation in apple fruit and fruit quality, selecting Aksu Fuji apple as the research object, contents of each fruit sugar components in three hormone treatments of IAA, GA3 and 6-BA were determined by using thermal titration and colorimetric methods, and correlation and signifi cance of the data were analyzed. The results show that based on accumulation amount of sugar component in mature fruit of Aksu Fuji apple from high to low, the order is total sugar, reducing sugar, fructose, glucose, sucrose, fructose, and fructose accounts for the largest proportion of total sugar. Effects of IAA 500 mg/L, GA3 250 mg/L and 6-BA 250 mg/L treatments on sugar accumulation are the most signifi cant, and fruits have better quality. Fruit quality of Aksu Fuji apple can be comprehensively evaluated based on sweetness value, fructose has the largest contribute to sweetness value and the most signifi cant effects on total sugar.
