摘要
以从山西、河北引进至新疆的8个引进鲜食枣品种为试材,对果实品质指标动态变化进行了分析,了解各个指标的变化趋势和含量高低,进而比较各品种之间的鲜果品质。结果表明:从白熟期至完熟期阶段,各枣品种单果重呈先上升后略有降低的趋势,可溶性总糖含量逐步升高,维生素C含量呈"高-低-高-低"的变化趋势,可溶性蛋白质含量先升高后降低,有机酸含量呈"高-低-高"的变化趋势,淀粉、纤维素含量呈现"高-低-高"的变化趋势;通过主成分分析法构建综合评价模型,对8个引进枣品种鲜果果实品质进行综合评价,最后得出"金谷大枣"的综合品质较好。
Taking eight kinds of introduced jujube fruit from Shanxi and Hebei to Xinjiang as materials,by analyzing the quality indexes dynamic changes of eight kinds of introduced jujube fresh fruits,the change trend and the content of each index were studied,then to make comparisons among the different varieties of fresh fruit quality.The results showed that,changing trend of each jujube fruit weight was‘up-down＇,from the stage of white-ripe to full ripe,and the content of total soluble sugar increased gradually,vitamin C content showed a trend of‘high-low-high-low＇.The changing trend of soluble protein content was‘up-down＇,the organic acid content showed a trend of‘high-low-high＇,and starch and cellulose content presented the trend of‘high-low-high＇;The conclusion of comprehensive evaluation of 8varieties of jujube fruit quality was that the comprehensive quality of‘Jingu jujube＇was the best through comprehensive evaluation model constructed by principal component analysis.
