ABSTRACT

The effects of intercropping grapevines with the medicinal aromatic plants (MAPs) basil, lemon balm and sage, on berry volatile compounds of grapevine cv. Sangiovese were evaluated under field conditions. MAPs were cultivated in the rows of a mature vineyard. The introduction of MAPs in the vineyards slowed down technological ripening and increased total VOCs in Sangiovese berries. Among the different VOCs classes, C₁₃-norisoprenoids, vanillins, and phenols showed significantly higher concentrations in berries of grapevine intercropped with MAPs. The presence of MAPs enhanced berry concentration of: vomifoliol (C₁₃-norisoprenoids), homovanillic alcohol, and homovanillic acid (vanillins), 4-vinylguaiacol, syringol and 3,4,5-trimethoxyphenol (phenols) and 3-methyl-2-buten-1-ol (aliphatic alcohols), while reducing the level of p-cymen-7-ol, 1-hexanol and nerol. Data suggest that intercropping with MAPs could influence the accumulation of VOCs in grapevines and contribute to the composition and volatile profile of this cultivar.

摘要

葡萄藤与药用芳香植物 (MAPs) 罗勒、香蜂草和鼠尾草间作对葡萄藤 cv. 浆果挥发性化合物的影响。桑娇维塞在野外条件下进行了评估。MAPs 在成熟的葡萄园中种植。在葡萄园中引入 MAP 减缓了技术成熟，并增加了桑娇维塞浆果中的总 VOC。在不同的 VOCs 类别中，C ₁₃ -norisoprenoids、香草醛和酚类在与 MAPs 间作的葡萄浆果中显示出显着更高的浓度。MAPs 的存在提高了浆果的浓度：伏米叶醇（C ₁₃-norisoprenoids）、高香草醇和高香草酸（香草醛）、4-乙烯基愈创木酚、紫丁香酚和 3,4,5-三甲氧基苯酚（苯酚）和 3-甲基-2-丁烯-1-醇（脂肪醇），同时减少p-cymen-7-ol、1-己醇和橙花醇的含量。数据表明，与 MAPs 间作可能会影响 VOCs 在葡萄藤中的积累，并有助于该品种的组成和挥发性特征。
