Comprehensive Evaluation of Fruit Quality of Actinidia arguta Based on Principal Component Analysis and Cluster Analysis
摘要
Abstract
In order to scientifically evaluate the fruit quality of different Actinidia arguta varieties and establish the quality evaluation system,10 Actinidia arguta varieties were used as experimental materials,and the indexes of fruit appearance quality and nutritional quality were measured and compared under edible conditions.The fruit quality of Actinidia arguta was comprehensively evaluated by correlation analysis,principal component analysis and cluster analysis.The results showed that the quality indexes of different varieties of Actinidia arguta were different and correlated.The difference of the content of Vitamin C was largest,and the coefficient of variation was 53.08%.The difference of fruit color brightness(L*value)was the smallest,and the coefficient of variation was 6.04%.By principal component analysis,18 quality indicators were simplified into 6 principal components,and the cumulative variance contribution rate was 90.571%,which could reflect most of the information of the original quality indexes.The comprehensive scores of quality indexes of 10 Actinidia arguta varieties were ranked as'Longcheng No.2','Kuilü','Jialü','Wanlü','Tianxinbao','Lübao','Xinlü','Cuiyu','Fenglü'and'Pingllü'.According to cluster analysis,10 Actinidia arguta varieties were divided into five categories,among which'Longcheng No.2'and'Kuilü'in the first category had better comprehensive quality traits.The study provided a reference for the variety breeding,planting,extension and rational processing and utilization of Actinidia arguta.关键词
