摘要
Abstract
[Objective] In order to determine the main evaluation indexes of fruit quality of fresh jujube cultivars,the main quality indexes of the 16 introduced kinds of fruits will be analyzed and the correlation between them will be studied,too.[Method] The main quality indexes of 16 fresh jujube cuhivars were screened by principal component analysis and cluster analysis.[Result] The correlation analysis showed that there were relative independence and close correlation between the 12 quality indexes of fresh jujube fruit.According to the principal component analysis,the top 5 fresh jujube varieties in the 16 kinds of fresh jujube varieties in turn were Huluzao,Zan No.1,Zanjing,Zanhuagnxianshi and Shanxi egg jujube,followed by Yanchuantiaozao,Yuanling No.1 and Jinsimizao.[Conclusion]The 16 kinds of fresh fruit jujube varieties could be divided into 7 key factors so as to establish comprehensive evaluation system of sample quality.Cluster analysis results showed that 16 introduced fresh jujube cultivars could be divided into three groups and in the end,the top five in comprehensive ranking of the 16 varieties were:Huluzao,Zan No.1,Zanjing,Zanhuagnxianshi and Shanxi egg jujube,followed by Yanchuantiaozao,Yuanling No.1 and Jinsimizao.关键词
