【摘要】 评价、筛选综合性状良好的鲜食枣品种,为优良鲜食枣品种的繁殖与发展提供参考,并为鲜食枣果的综合评价、枣树优良品种的选育以及开发利用提供科学依据。以筛选出的19个具有发展潜力的鲜食枣品种为研究对象,测定有关果实品质的12个指标,对果实品质进行分析,并通过相关性分析和主成分分析进行综合评价。结果表明:鲜食枣的12个性状指标既相互联系,又相对独立;利用主成分分析,抽取出的4个成分涵盖了原始信息的83.972%,其中得分最高的前3个品种分别为‘晋矮3号’‘不落酥’和‘晋矮2号’,各鲜食枣品种在实际中的表现与分析结果基本一致,在枣果品质的评价中取得了比较理想的结果。更多还原

【Abstract】 The evaluation and screening of fresh jujube varieties with good comprehensive characters could provide information for the development of fresh jujube,and provide scientific basis to the breeding and development of fine jujube varieties. Taking 19 fresh jujube varieties with development potential as materials,12 fruit quality indices were determined and evaluated by correlation analysis and principal component analysis. The results showed that the fruit quality indices interrelated with each other. The four components covered 83.972% of the original information.The score of ’Jinai No.3’,’Buluosu’ and ’Jinai No.2’ ranked the top 3. The analysis results were basically consistent with the actual performance of these fresh jujube varieties.更多还原
