摘要:

以71份枣种质半红期果实为材料,测定不同种质的口感质地特性、水溶性果胶、离子型果胶、共价型果胶、纤维素、半纤维素等细胞壁组分含量,并进行相关性、主成分分析和综合评价,解析枣果质地差异的形成原因。结果表明,离子型果胶和共价型果胶变异系数较高,果肉致密指数变异系数最低。相关性分析表明,口感评价指标与水溶性果胶、离子型果胶、总果胶、果肉致密指数相关性最高。通过主成分分析,得出水溶性果胶、共价果胶共价型果胶、离子型果胶/共价型果胶、总果胶/(半纤维素 + 纤维素)为影响果实质地的重要因素。71份种质的口感总分范围为3 ~ 10分,综合评价H值在-1.18 ~ 1.10之间,总体上,综合评分能反映果实的口感品质;鲜食种质细胞壁含量显著低于兼用和制干种质,兼用种质与制干种质差异不显著。

Abstract:

Using fruits of 71 jujube germplasms at the half-red stage as test materials,this study determined the taste and textural properties as well as the contents of cell wall components including water-soluble pectin,ionic-soluble pectin,covalently-souble pectin,cellulose and hemicellulose in different germplasms. Correlation analysis,principal component analysis and comprehensive evaluation were further conducted to clarify the formation mechanism of textural differences in jujube fruits. The results showed that ionic-soluble pectin and covalently-souble pectin exhibited relatively high coefficients of variation,while the fruit texture index had the lowest variation coefficient. Correlation analysis revealed that taste evaluation indicators were most closely correlated with water-soluble pectin,ionic-soluble pectin,total pectin and fruit texture index. Principal component analysis identified water-soluble pectin,covalently- souble pectin,the ratio of ionic-soluble pectin to covalently-souble pectin,and the ratio of total pectin to the sum of hemicellulose and cellulose as the key factors affecting jujube fruit texture. The total taste scores of the 71 germplasms ranged from 3 to 10,and the comprehensive evaluation H values varied from-1.18 to 1.10,indicating that the comprehensive scores could effectively reflect the fruit taste quality. The cell wall component contents of fresh-eating jujube germplasms were significantly lower than those of dual-purpose and dry germplasmss,whereas no significant difference was observed between dual-purpose and dry germplasmss.
