    摘要:

    综合评价制干枣主要栽培品种的品质,为制干枣品种选择和生产利用提供科学依据。应用SPSS统计分析软件,采用因子分析对13个制干枣品种的品质性状进行了比较和排序。结果表明:(1)在13个制干枣品种中,制干率和干枣含糖量差别较小,而单果质量、果实整齐度、果皮韧性和汁液差异相对较大;各品质因子间既相互独立又存在着不同程度的相关。(2)在9个品质性状指标中,单果质量、制干率、干枣口感、干枣含糖量和果皮韧性等5个指标起决定作用。(3)因子分析结果表明,制干品质综合性状优良的品种是相枣和板枣,临汾团枣、洪赵小枣和中阳木枣相对较差,其它品种居中,这一结果与感官评价的结果基本一致。本研究表明:应用因子分析可以较好地用于制干枣品种品质性状的综合评价。

    Abstract:

    Comprehensive review of quality characters of main cultivars may offer scientific foundation for select and production use of dry-jujube. Using SPSS analytical soft, comprehensive character of thirteen dry-jujube varieties fruit quality 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 smaller, but differences of the target on fruit weight, toughness of fruit skin and juice of flesh were bigger and there is either relative independence or close correspondence among the characteristics indicators of fruit quality. (2) In thirteen quality factors effecting 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 result of factor analysis showed that the comprehensive quality of Xiangzao and Banzao were best, Linfentuanzao, Hongzhaoxiaozao and Zhongyangmuzao were bad comparatively, and the result was similar to sensory review of the varieties. The result showed the method of factor analysis was better to reviewing comprehensively dry-jujube fruit quality properties.
