Factor Analysis and Comprehensive Assessment on Quality Characters of Dry-jujube Cultivars

Fruit quality characteristics of thirteen dry-jujube cultivars was compared and sorted by factor analysis.The result showed that:(1)differences of the target on radio of edibility,radio of dried fruit and saluble sugar content of dried fruit were small,but differences in fruit weight,toughness of fruit skin,and juice of flesh were big.There was either relative independence or close correspondence among the characteristics of fruit quality.(2) Among the nine quality factors affecting dried jujube fruit quality,fruit weight,radio of dried fruit,evaluation of taste,saluble sugar content of dry-jujube fruit,and toughness of fruit skin decide fruit quality.(3) The results of factor analysis showed that the comprehensive quality of Xiangzao and Banzao were the best.Linfentuanzao,Hongzhaoxiaozao,and Zhongyangmuzao were bad comparatively.These results were similar to sensory review of the cultivars.Based on the results of this study,factor analysis is a reliable method for reviewing comprehensively dry-jujube fruit quality properties.
