摘　　要：本研究选取北京地区33家种植园区24个番茄品种共计45份番茄样品,调查不同果型成熟果实的可溶性固形物含量和表型性状指标(横径、纵径、果形指数、单果重和果皮厚度),继而对果实表型性状与可溶性固形物含量进行相关分析,探讨品种和栽培条件、技术对番茄品质的影响。结果表明:番茄表型性状指标相互影响,单果重与横径、纵径和果皮厚度呈显著正相关;可溶性固形物含量与果实横径、纵径、单果重和果皮厚度呈显著负相关。聚类分析表明,栽培条件与技术对番茄果实的影响较大,甚至超出品种间差异。本研究结果表明通过正确选择番茄品种及配套栽培管理技术等途径可实现番茄品种特性保持和品质提升。In this study,45 samples from 24 tomato varieties in 33 plantations were collected in Beijing area.The soluble solid content and phenotypic traits(including longitudinal diameter,transverse diameter,fruit shape index,pericarp thickness and single fruit weight)of ripe fruits were investigated.The effects of varieties,conditions and techniques of cultivation on tomato quality were studied by analyzing fruit phenotypic traits,soluble solid content and their correlations.The results showed that the phenotypic traits of tomato affected each other.The single fruit weight was significantly positively correlated with longitudinal diameter,transverse diameter and pericarp thickness,while the soluble solid content was significantly negatively correlated with longitudinal diameter,transverse diameter,single fruit weight and pericarp thickness.Cluster analysis results revealed that the conditions and techniques of cultivation had great impacts on tomato fruits,even beyond the differences between varieties.The results in this study suggested that the tomato variety characteristics should be maintained and the quality should be improved through proper selection of varieties and supporting cultivation and management techniques.
