摘　　要：为了直观地比较出洛川、安塞、铜川等10个不同产地富士苹果品质的差异,对富士苹果外在、内在、加工品质三方面进行测定,采用主成分分析和聚类分析法,对其单果重、果皮色泽、可溶性固形物、酸度和硬度等12个主要果实品质指标进行了分析。结果表明,在果实品质评价的12个主成分中,提取出的4个主成分的累积贡献率达到85.439%,可以反映品质的大部分信息,简化后的品质评价指标为单果重、果形指数、可溶性固形物、酸和出汁率。各产地富士苹果综合品质高低的顺序为:阿克苏>静宁>三门峡>烟台>延安>安塞>天水>洛川>铜川>扶风。By the principal component analysis and cluster analysis, 12 main fruit quality index of Fuji apple were determined ,generally including external, internal and processing quality,detailed including the weight of single fruit,skin color and luster,soluble solid content,acidity and hardness etc,the purpose was to be more intuitive compare the difference of Fuji apple＇s quality with 10 different regions,including Luochuan,Ansai and Tongchuang etc. The results showed that the quality of the simplified evaluation index were weight of single fruit,fruit shape index,soluble solid content,acid and juice yield. Extracting five main components from 12 principal fruit quality evaluation, it could reflect the most of the information about quality and its contribution rate reached 85.439% .It got an order from high to low about Fuji apple＇s comprehensive quality with different regions, Akesu〉J ingning〉Sanmenxia〉Yantai〉Yan ＇ an〉Ansai〉Tianshui〉Luochuan〉Tongchuan〉Fufeng.
