摘要: 采用主成分分析和聚类分析法对30?个樱桃品种的主要营养性状(单果质量、pH值、总糖、还原糖、总酸、VC、花色苷)进行测定分析,筛选优异品种,为樱桃资源开发利用提供依据。结果表明:不同品种樱桃果实营养性状存在显著差异,单果质量、总糖、还原糖、VC的变异系数较大,pH值、总酸、花色苷的变异系数较小,部分营养性状之间存在简单的相关性。主成分分析结果显示,第1主成分、第2主成分特征值都大于1,并且累计方差贡献率达到67.718%,前2?个主成分反映了原始变量的绝大部分信息。以综合成分中主要因子为指标进行聚类分析,可将30?个樱桃品种分为5?大类,各类间营养性状上有较大差异。利用主成分分析和聚类分析综合评价得出,红蜜、13-33、秦林3?个樱桃综合品质高,可作为樱桃育种、品质改良及樱桃资源开发利用的原材料。

Abstract: The main fruit nutritional traits (single fruit mass, pH, and the contents of total sugar, reducing sugar, total acid, vitamin C and anthocyanin) of 30 cultivars of Chinese cherry (Prunus pseudocerasus Lindl.) were measured and analyzed by principal component analysis (PCA) and cluster analysis (CA) in order to select superior cultivars. The results showed significant differences in fruit nutritional traits among different cultivars of Chinese cherry. The coefficients of variation (CV) of single fruit mass and the contents of total sugar, reducing sugar, and vitamin C (VC) were larger than those of other indices, and a simple correlation was observed between some nutritional indices. PCA analysis showed that the first principal component 1 (PC1) and the second principal component (PC2) presented a characteristic value greater than 1, and their cumulative variance contribution rate was 67.718%, suggesting that both PCs could reflect most of the information about the original variables. Cluster analysis divided the 30 cultivars into five types, which differed greatly in fruit nutritional traits. In general, our results showed that the cultivars Red Honey, 13-33 and Qin-Lin had the best quality, and they could be utilized directly or modified for better fruit quality.
