基于因子分析的无花果引进品种果实品质性状综合评价
Factor Analysis and Comprehensive Evaluation of Fruit Quality Traits of Introduced Fig Cultivars
摘要
Abstract
The study aimed to establish a comprehensive evaluation system for the fruit quality of 5 fig cultivars and to provide evidence for the selection of fine cultivars.Totally 5 fig cultivars introduced into and grown in Xinjiang from Shandong,'Blanrick','Fengchanhuang','Violette Solise','Meiliya' and 'Bojihong' were collected to determine 4 appearance indexes and 10 nutritional quality indexes and these were subsequently evaluated by correlation analysis and factor analysis.Besides,these cultivars were sorted according to their comprehensive quality scores.The results showed that the intercultivar variations of 14 fruit quality traits were different;the highest difference was observed for vitamin C,fruit weight,titratable acid,sugar to acid ratio,solid to acid ratio and magnesium content were at a moderate level,and the rest varied relatively less.Moreover,different correlations among all quality indexes were found depending on cultivar.By factor analysis,3 common factors with an eigenvalue greater than 1 were extracted,cumulatively contributing to 93.486％ of the total variance.The contribution rate of the first common factor including fruit weight,fruit longitudinal diameter,titratable acidity,sugar to acid ratio,solid to acid ratio,and iron,magnesium and calcium contents was 47.242％,the contribution rate of the second common factor including fruit transverse diameter,fruit shape index and vitamin C content was 27.150％,and the contribution of the third common factor including soluble sugar,soluble solids and potassium content was 19.094％.Using the comprehensive quality evaluation model,the fruit quality of 5 fig cultivars was ranked in the decreasing order of 'Blartrick','Meiliya','Violette Solise','Bojihong' and 'Fengchanhuang'.关键词
