In this study, 50 tomato landraces grown in Turkey were investigated in terms of their secondary metabolite profiles. Each accession was planted in 2016 and 2017 in 3 replicates in an open field. In this study, color, pH and brix of the fruit samples were measured and an unbiased LCMS-based metabolomics approach was applied. Based on Principal Components Analysis (PCA) and Hierarchical Cluster Analysis (HCA) of the relative abundance levels of >250 metabolites, it could be concluded that fruit size was the most influential to the biochemical composition, rather than the geographical origin of accessions. Results indicated substantial biodiversity in various metabolites generally regarded as key to fruit quality aspects, including sugars; phenolic compounds like phenylpropanoids and flavonoids; alkaloids and glycosides of flavour-related volatile compounds. The phytochemical data provides insight into which Turkish accessions might be most promising as starting materials for the tomato processing and breeding industries.
在这项研究中，调查了土耳其种植的 50 种番茄地方品种，以研究它们的次生代谢产物图谱。每个品种于 2016 年和 2017 年在 3 个重复的露地中种植。在这项研究中，测量了果实样本的颜色、pH 值和白利糖度，并应用了一种基于 LCMS 的无偏代谢组学方法。基于 >250 种代谢物相对丰度水平的主成分分析（PCA）和层次聚类分析（HCA），可以得出结论，果实大小是影响生化成分的最主要因素，而不是品种的地理来源。结果表明，在各种通常被认为是果实品质方面关键的代谢物中存在着大量的生物多样性，包括糖；苯丙烷类和类黄酮等酚类化合物；生物碱和风味相关挥发性化合物的糖苷。这些植物化学数据可以深入了解哪些土耳其品种可能最有希望成为番茄加工和育种产业的起始材料。
