摘要: 为综合评价不同甜瓜品种的品质差异,以天津市西青区设施栽培的‘绿宝石二号’‘羊角蜜’‘博洋九号’3个不同薄皮甜瓜品种果实为试材,对甜瓜的外形性状(果形、大小、质量、果形指数、果皮颜色、果实硬度、果肉厚度、果皮厚度)及品质性状(可溶性糖、可滴定酸、糖酸比、维生素C、可溶性固形物、感官评价)指标进行了测定,并运用主成分分析法对果实品质进行综合评价,建立甜瓜果实品质评价模型,筛选适宜天津市西青区种植的甜瓜品种。结果表明,经因子分析并基于特征值大于1的原则,共提取2个主因子,累计方差贡献率达100%。因子分析综合得分模型显示,薄皮甜瓜综合得分排名为‘羊角蜜’>‘博洋九号’>‘绿宝石二号’,本研究可为天津设施栽培甜瓜品种选择提供依据。

Abstract: In order to comprehensively evaluate the quality differences of different melon varieties, this paper used the fruits of three different thin-skinned melon varieties ‘Lvbaoshi No. 2’ ‘Yangjiaomi’ and ‘Boyang No. 9’ cultivated in facilities in Xiqing District of Tianjin as test materials, the appearance characters(fruit shape, size, weight, fruit shape index, peel color, fruit hardness, pulp thickness and peel thickness)and quality traits(soluble sugar, titratable acid, sugar acid ratio, vitamin C, soluble solids and sensory evaluation)of melon were measured. The principal component analysis method was used to comprehensively evaluate the fruit quality, and screen the melon varieties suitable for planting in Xiqing District, Tianjin. The results showed that after factor analysis and based on the principle that the eigenvalue is greater than 1, two main factors were extracted from thin-skinned muskmelon, and the cumulative variance contribution rate reached 100%. The comprehensive score model of factor analysis showed that the comprehensive score ranking of thin-skinned melon is ‘Yangjiaomi’ ‘Boyang No. 9’ and ‘Lvbaoshi No. 2’. This study can provide a basis for the selection of melon varieties under facility cultivation in Tianjin.
