摘　　要：以"长富2号"红富士苹果(Malus domestica‘Red Fuji’,Nagafu No.2)为母本,9个授粉品种为父本,进行人工授粉,研究授粉处理对红富士苹果成熟期果实品质的影响,并构建基于主成分分析的综合评价函数。结果表明:果实的花青苷、单果重、维生素C、固酸比、可溶性糖、可溶性蛋白、可滴定酸等主要经济性状,各授粉处理间差异较大,果形指数、硬度差异较小;主成分分析提取6个主成分,累计方差贡献率达96.02%,根据主成分得分和方差相对贡献率构建综合评价函数,由综合评价函数确定9个授粉处理果实的综合品质由高到低的排序为雪球、美红、火焰、红星、道格、全家红、绚丽、荷红、粉芽。‘Red Fuji'Nagafu No.2 was used as female parent and nine varieties were used as male parents to study the effects of pollination treatments on mature fruit of‘Red Fuji'apple by synthetical evaluation function based on principal component analysis.The results showed that there were significant differences on main economic characters of fruit such as anthocyanin,fruit weight,vitamin C,ratio of TSS to acid,soluble sugars,soluble protein and titratable acidity.However,there was no obvious difference on fruit shape index and firmness.Six principal components(PC)whose total cumulative contribution reached 96.02% were extracted by principal component analysis.The synthetical evaluation function was composed of scores of principal components and relative variance contribution.From high to low,the arranging order of the synthetical scores of the nine pollination treatments,which were assessed by the synthetical evaluation function,was‘Xueqiu', ‘Meihong', ‘Huoyan', ‘Starking', ‘Daoge',‘Quanjiahong',‘Xuanli',‘Hehong'and‘Fenya'.
