An alternative to improve grape quality is the elicitor application to the vineyard due its implication to induce defense mechanisms involved in the synthesis of secondary metabolites. There are few studies about the influence of elicitors on grape volatile composition. The aim of this work was to investigate the influence of methyl jasmonate (MeJ) foliar application to Tempranillo grapevines on grape aroma composition over three consecutive vintages. In the first vintage, MeJ treatment improved p-cymene, methyl jasmonate, and hexanal synthesis, and degraded 2-hexen-1-ol acetate, (Z)-3-hexen-1-ol, and n-hexanol. In the second season, the content of several terpenes, β-damascenone, methyl jasmonate, esters, benzenoids and (Z)-3-hexen-1-ol was diminished after MeJ application. In the third vintage, the synthesis of several volatile compounds considered positive contributors for grape aroma was improved by MeJ application. In conclusion, the effect of MeJ foliar application on grape volatile content was mainly dependent on the vintage.

改善葡萄质量的另一种方法是将引诱剂应用于葡萄园，因为它暗示了诱导与次生代谢产物合成有关的防御机制。关于引发剂对葡萄挥发性成分影响的研究很少。这项工作的目的是调查茉莉酸甲酯（MeJ）叶面施用于Tempranillo葡萄藤在三个连续年份中对葡萄香气成分的影响。在第一个年份中，MeJ处理改善了对伞花烯，茉莉酸甲酯和己醛的合成，并降解了乙酸2-己烯-1-醇，（Z）-3-己烯-1-醇和正己醇。在第二个季节，几个萜烯的含量，βMeJ施用后，β-大马烯酮，茉莉酸甲酯，酯，苯类化合物和（Z）-3-hexen-1-ol减少。在第三个年份，MeJ的应用改善了几种挥发性化合物的合成，这些化合物被认为是葡萄香气的积极贡献者。总之，MeJ叶面施肥对葡萄挥发物含量的影响主要取决于年份。
