摘要
【目的】确定引进鲜食枣品种果实品质的主要评价指标,分析测定16个引进鲜食枣品种果实的主要品质指标,分析研究16个品种果实品质性状间的相关性。【方法】采用主成分分析法和聚类分析法对引进的16个鲜食枣品种果实的主要品质指标进行筛选。【结果】鲜食枣果实12个品质指标之间存在相对独立性和密切相关性;根据主成分分析主因子综合得分,16种引进鲜食枣品种综合排名前5位的鲜食枣品种依次为葫芦枣、赞1、赞晶、赞皇鲜食和陕西鸡蛋枣,延川条枣、圆铃1号和金丝蜜枣排名居后。【结论】主成分分析将16个鲜食枣品种12种果实品质简化为7种关键因子指标,建立针对公式样品品质的综合评价体系,将供试16种引进鲜食枣品种分为三大类群。最终确定供试16种引进鲜食枣品种果实综合排名前5位的鲜食枣品种依次为葫芦枣、赞1、赞晶、赞皇鲜食和陕西鸡蛋枣,延川条枣、圆铃1号和金丝蜜枣排名居后。
【Objective】In order to determine the main evaluation indexes of fruit quality of fresh jujube cultivars,the main quality indexes of the16introduced kinds of fruits will be analyzed and the correlation between them will be studied,too.【Method】The main quality indexes of16fresh jujube cultivars were screened by principal component analysis and cluster analysis.【Result】The correlation analysis showed that there were relative independence and close correlation between the12quality indexes of fresh jujube fruit.According to the principal component analysis,the top5fresh jujube varieties in the16kinds of fresh jujube varieties in turn were Huluzao,Zan No.1,Zanjing,Zanhuagnxianshi and Shanxi egg jujube,followed by Yanchuantiaozao,Yuanling No.1and Jinsimizao.【Conclusion】The16kinds of fresh fruit jujube varieties could be divided into7key factors so as to establish comprehensive evaluation system of sample quality.Cluster analysis results showed that16introduced fresh jujube cultivars could be divided into three groups and in the end,the top five in comprehensive ranking of the16varieties were:Huluzao,Zan No.1,Zanjing,Zanhuagnxianshi and Shanxi egg jujube,followed by Yanchuantiaozao,Yuanling No.1and Jinsimizao.
