通过测定‘凤梨释迦’的单果重、果形相关因子和可溶性固形物含量,并对各指标进行主成分分析和聚类分析,旨在为‘凤梨释迦’果实分级提供参考。结果表明:‘凤梨释迦’果实偏斜度变异系数最大,大果面厚变异系数最小;各果形指标间及其与果实品质的关系密切,其中可溶性固形物含量与单果重呈极显著正相关,与偏斜度呈极显著负相关;主成分分析和聚类分析结果表明‘凤梨释迦’果实分级标准决定因子应以代表果实大小的单果重等指标为主,以代表果实形态的果形指数和代表偏斜度的偏斜指数为辅助因子。 Through measuring the fruit weight, fruit shape factor and soluble solid content of ’Bromeliad’, the principal component analysis and clustering analysis of each index were carried out to provide reference for the grading of ’Pineapple’. The results showed that the coefficient of skewness was the highest and the coefficient of variation of the fruit face thickness was the smallest. The fruit shape index was closely related to the fruit quality, and the content of soluble solids and fruit weight were extremely significantly positive Correlation analysis and skewness showed a significant negative correlation; principal component analysis and cluster analysis showed that the ’pineapple Shajiao’ fruit grading criteria determining factor should be based on the size of the fruit and other indicators of single fruit weight to represent the fruit shape fruit The form factor and the skewness index representing the skewness are cofactors.
