| 摘 要： | 以20个不同产地杨小-26南丰蜜橘为试材,对其单果重、果形指数、出汁率、囊瓣数、化渣度、可溶性糖、可滴定酸、Vc、SSC等9个主要果实品质指标进行了观测。主成份分析结果表明,前6个主成份的累积贡献率达95.20%,将前6个主成份特征向量进行系统聚类分析,在最大距离为1.00时可划分为5个类别:可滴定酸、Vc单列为一类,果形指数与出汁率、化渣度与囊瓣数分别聚为一类,单果重、可溶性糖和SSC 3个指标同聚为一类。因此,简化后的5项果实品质评价指标可以反映南丰蜜橘品质的绝大部分信息,为科学评价南丰蜜橘果实品质提供了理论依据。

| Abstract: | The main fruit quality indices such as simple fruit weight,fruit shape index,juice percentage,soluble sugar,tritrable,vitamin C and soluble solids content in Nanfeng tangerine cv 'Yangxiao-26' coming from twenty different cultivating regions were studied by using multivariate statistics.The selection types of fruit quality factors were confirmed by means of principal component analysis and systematic cluster analysis.The results revealed that the cumulative proportion of the former 6 principal components re... |
