摘要
以贵州省威宁地区种植的5个大樱桃品种为试材,探讨品种间果实外观及内质指标的差异显著性,并对品质进行综合评价,旨在为大樱桃引种栽培提供参考。结果表明:不同品种间单果质量、可溶性固形物、可溶性糖、糖酸比等12项果实品质指标差异显著。单果质量与可溶性固形物、可溶性糖、糖酸比及固酸比,可溶性固形物与横径,固酸比与糖酸比、可溶性糖,呈显著相关性;12项指标反映的品质可用3个主成分来表示,累计贡献率达93.55%,第1主成分值在综合品质评价上起关键作用,5个大樱桃品种中布鲁克斯和斯帕克里综合品质较优,桑提娜属中等,黑珍珠和艳阳较差。
To select the best sweet cherry cultivar in Weining County,Guizhou Province, the exter- nal/internal quality parameters of five sweet cherry cultivars were quantified and comprehensively evalu- ated.The results showed that 12 indices including fruit weight, content of soluble solid, content of soluble sugar,and ratio of soluble sugar to titratable acid etc, varied highly among five cultivars.There were sig- nificant correlations between the fruit weight and the content of soluble solid, content of soluble sugar, or ratio of soluble sugar to titratable acid, or ratio of content of soluble solids to titratable acid; between the content of soluble solid and fruit diameter; between the ratio of content of soluble solids to titratable acid and ratio of content of soluble sugar to titratable acid, or content of soluble sugar. The cumulative contribution of three principal components was 93.55 % and all the 12 indices were involved.Based on the comprehensive evaluation model of fruit quality, the first principle component played a key role in fruit quality.The best cultivars were Brooks and Spar kerry, followed by Santina. The least ones were Black pearl and Yanyang.
