中国石榴品种资源经济性状研究

本文测定了34个中国石榴主栽品种的单果重、可溶性固形物含量、糖酸比等9个经济性状,根据测定结果对各品种果实品质进行了模糊综合评判.结果表明,皖榴3号、皖榴2号、皖榴1号、大笨子等品种品质最佳;提出了评判结果等级划分的方法;各品种经济性状的相关与回归分析结果显示,果实百粒重与出汁率,可溶性固形物含量、可溶性糖含量与糖酸比,出汁率与糖酸比,糖酸比与可溶性糖含量均呈极显著正相关(α=0.01,F＞F0.01);出汁率与果皮光洁度呈极显著负相关(a=0.01,F＞0.01);主成分分析结果表明,前5个主成分累积方差贡献率达到87.67%,基本概括了全部9个性状的主要信息.

Economic Characteristics of Fruits in Pomegranate Cultivars in China

Fuzzy synthetic evaluation was done by using nine economic characteristics of fruits in 34 pomegranate cultivars in China. The results showed that the synthetic fruit quality of Wanliu No.3, Wanliu No.2, Wanliu No.1 and Dabenzi were ranked first, and the proper grading method was postulated. The results of correlation and regression analysis of economic characteristics showed that 100 grain weight and juice content, and soluble solid substance and sugar content, the ratio of sugar and acid, and juice content and the ratio of sugar and acid, and the ratio of sugar and acid and sugar content had the extremely remarkable positive correlation, while juice content and peel smoothness had the extremely remarkable negative correlation. The results of principal component analysis showed that cumulative variances about the front five principal components had reached 87 67%, which could represent all the information of nine economic characteristics.
