摘要:

选取52个中早熟品种苹果测定22项理化营养指标,采用主成分分析(PCA)及聚类分析(HCA)方法对指标进行分析。结果表明:苹果多个品质指标变量间存在着相对独立性和密切相关性,前7个主成分累积方差贡献率达到72.8%,聚类分析结果显示品质指标分为8类较为合理。最终选定可溶性固形物、糖酸比、褐变度、镁含量、果实硬度、果形指数、单果质量和果肉细胞大小8个具代表性的指标来评价中早熟苹果的品质。

Abstract:

In order to provide a theoretical basis for the selection of indicators for evaluating the quality of apple fruits,
22 quality parameters of 52 mid-early ripening apple cultivars were determined and analyzed by principal component
analysis and hierarchical cluster analysis. Results revealed either relative independence or close correspondence among the
characteristic indicators of fruit quality. The cumulative variance contribution ratio of the first seven principal components
of PCA was up to 72.8%. The 52 apple cultivars were classified as 8 major groups by HCA on the basis of the measured
parameters. Eight factors were suitable for a comprehensive system for the evaluation of apple quality, including the content
of total soluble solids, sugar/acid ratio, browning degree, the content of magnesium, fruit firmness, fruit shape index, single
fruit weight and pulp cell size.

Key words: mid-early ripening apple cultivars, quality, evaluation factor
