ABSTRACT In the present study, we focus on the analysis of the volatile organic compound (VOC) contents in the grain of a representative set of winter wheat cultivars grown in Central Europe. The cultivars were grown in control conditions or were inoculated with the fungus Fusarium culmorum. In the analysed samples, hydrocarbons, alcohols, aldehydes and ketones, aromatics, terpenes and others were found. Among them, results for terpenes seem particularly important. The discriminant analysis allowed complete separation of the quality groups of wheat based on VOCs. Simultaneously, a genetic matrix was created based on the genetic distance between the wheat cultivars and the Mantel test was used to compare it with the VOC matrix. The analysis revealed relationships between the genetic matrix and the overall VOCs, as well as terpenes. The obtained results indicate a significant relationship between microorganisms that exist in the environment, genetic features of plants and VOCs formed in the grain.

接种和未接种冬小麦品种中以萜类化合物为重点的挥发性有机化合物与遗传基质的关系

摘要 在本研究中，我们重点分析了在中欧种植的一组代表性冬小麦品种的谷物中的挥发性有机化合物 (VOC) 含量。栽培品种在对照条件下生长或用真菌 Fusarium culmorum 接种。在分析的样品中，发现了烃类、醇类、醛类和酮类、芳烃、萜烯等。其中，萜烯的结果似乎特别重要。判别分析允许基于 VOC 完全分离小麦的质量组。同时，基于小麦品种之间的遗传距离创建遗传矩阵，并使用 Mantel 测试将其与 VOC 矩阵进行比较。分析揭示了遗传矩阵与整体 VOC 以及萜烯之间的关系。
