摘要: 以国家果树种质福州枇杷圃测定的果实品质性状数据为素材,分析测定了果实6 个品质性
状。结果表明:140 份种质的果实可溶性固形物含量、可溶性糖含量、可滴定酸含量、维生素C 含量、固
酸比、糖酸比等品质指标的变异系数在14.5% ~ 60.5%之间,6 项指标均不符合正态分布,基于等组距离
法提出了5 级分级标准和参照品种。

Abstract: The objective of this study is to establish the scientific quality evaluation indices of loquat
fruit. The relationship of 6 quality indices,including total soluble solid(TSS),soluble sugar(SS),titrable
acidity(TA),vitamin C(Vc),total soluble solid/titrable acidity(TSS/TA)and soluble sugar/titrable acidity
(SS/TA)was analyzed by statistical techniques based on 140 loquat accessions from National Fruit
Gene-pool of Loquat in Fuzhou City. The results showed that the coefficient variations of 6 indices from
the loquat germplasm were ranged from 14.5% to 60.5%,all of which did not meet the normal distribution.
The grade scale of each index could be divided into 5 levels by group distance method,then the reference
varieties were selected.

Key words: Eriobotrya japonica, germplasm resource, quality, flavor, evaluation indice
