摘要
为科学评价不同软枣猕猴桃品种果实品质,建立软枣猕猴桃果实品质评价体系,以 10个软枣猕猴桃品种为试验材料,在可食条件对其果实外观品质与营养品质等指标进行测定和比较,并运用相关性分析、主成分分析和聚类分析对软枣猕猴桃果实品质进行综合评价.结果表明,不同品种软枣猕猴桃果实品质指标存在差异性和相关性,其中维生素C含量差异最大,变异系数为 53.08%;果实色泽亮度(L*值)差异最小,变异系数为 6.04%.通过主成分分析将 18个品质指标简化为 6个主成分,其累计方差贡献率达 90.571%,能够反映原品质指标的大部分信息.10个软枣猕猴桃品种品质指标综合得分从高到低依次为'龙城 2号'、'魁绿'、'佳绿'、'婉绿'、'甜心宝'、'绿宝'、'馨绿'、'翠玉'、'丰绿'、'苹绿'.根据聚类分析将 10个软枣猕猴桃品种分为五类,其中第Ⅰ类的'龙城2号'与'魁绿'果实综合品质最优.该研究为软枣猕猴桃品种选育、种植推广及合理加工利用提供了参考.
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.
