摘要： 为给余甘子品质评价指标的确定提供理论依据，指导余甘子种质创新及果实开发，研究测定源自不同地区的12份余甘子资源的维生素C、可溶性固形物、可滴定酸、固酸比等主要品质指标，并采用主成分分析和聚类分析法对各品质指标进行分析，结果显示：心皮数和腹缝线在聚类指标中可不予以考虑，余下的18个指标进行聚类分析，首先单果重、果肉重、果核重、纵径、横径、果肉厚最先聚在一起；粗纤维、总酸、可溶性固形物等7个体现了果实质构的指标聚为一类；回甘度和果核粘离度聚为一类；最后Vc单独聚为一类。最终将品质指标简化为：单果重、粗纤维、回甘度、维生素C 4个主要因子。

Abstract: In order to provide a theoretical basis of germplasms evaluation for different Phyllanthus emblica provenances, 20 quality indicators of 12 different provenances of Phyllanthus emblica, including vitamin C, soluble solids, titratable acidity, acid ratio of main solid quality indicators, etc., were studied, and principal component analysis and cluster analysis method were used to analyze the various quality indicators. The results showed that: except the number of carpels and ventral suture index, the remaining 18 indicators of Phyllanthus emblica should be taken into consideration in the cluster analysis. The first factor consisted of fruits weight, pulp weight, stone weight, longitudinal diameter, diameter, flesh thickness; the second factor clustered 7 essence indicators of fruit structure, including crude fiber, total acidity, and soluble solids, etc.; the third factor clustered sticky sweet degrees and sticky degree from stone together; and finally, the forth factor was Vc clustering into a single category. The study suggested that quality evaluation indicators for Phyllanthus emblica eventually could be simplified as 4 main factors: fruit weight, crude fiber, sweet degrees and vitamin C.
