摘　　要：为构建毛花猕猴桃果实品质评价体系,利用DPSS软件对野生毛花猕猴桃可溶性糖、可滴定酸、维生素C、可溶性固形物等品质指标进行主成分分析。结果表明,果实变异系数差异明显,其中可溶性糖变异系数最大,达41.34%;主成分分析表明,将6个品质指标综合成3个主成分因子,可代表野生毛花猕猴桃果实品质的82.629%的信息量;综合评价结果表明,59、13、14、12、55、4、60、15、57、25、58号样品野生毛花猕猴桃果实品质优异,41、45、21、20、53、34、22、32号样品野生毛花猕猴桃果实品质较差。本研究对收集的野生毛花猕猴桃果实品质进行分析,找到了果实品质综合评价的3个主成分,揭示了不同野生毛花猕猴桃果实品质的差异。In order to build fruit quality evaluation system for Actinidia eriantha, we used DPSS software toperform the principal component analysis（PCA） of the quality indexes on A. eriantha, such as soluble sugar,titratable acid, vitamin C, soluble solid and so on. The results showed that the variable coefficient of the fruithad significant difference, and the variable coefficient of soluble sugar was the largest（41.34%）. Principalcomponent analysis showed that six quality indicators were integrated into three principal component factors,which could represent 82.629% of the amount of information of A. eriantha fruit quality. Comprehensiveevaluation of the results showed that the fruit qualities of the samples No.59, 13, 14, 12, 55, 4, 60, 15, 57, 25,58 were excellent, and that of the samples No. 41, 45, 53, 34, 20, 21, 22, 32 were poorer. Analyzing the qualityof the collected A. eriantha fruits, this study found out three principal components of the comprehensiveevaluation of fruit quality of A. eriantha, and revealed the diversity of the fruit quality of different A. eriantha.
