abstract = {Nanoparticles are emerging as a cutting-edge technology to improve crop agricultural input efficiency and reduce biotic and
abiotic stresses. In viticulture, nanoparticles hold promise for the sustainable application of an elicitor (methyl jasmonate,
MeJ), allowing a considerable dosage reduction. Herein, the influence of the foliar application of free MeJ (10 mM) and MeJ
nanoformulation (ACP-MeJ, 1 mM MeJ) on Tempranillo grape amino acids content over two vintages (2019 and 2020) was
evaluated. While both MeJ treatments provided a significant increase of the amino nitrogen and yeast assimilable nitrogen
in the must in 2019, there were no significant differences on these parameters in 2020. In 2019, MeJ treatment enhanced
the synthesis of most of the amino acids included in this study, while ACP-MeJ promoted the formation of six amino acids.
Hence, the content of total amino acids, with and without proline, was higher after applying MeJ than in the control musts.
However, these values were higher for control must than for MeJ samples in 2020. The multivariable analysis confirmed that
the vintage factor had a more prominent effect on the overall parameters of the musts. This strong influence of the vintage
could be related to the higher rainfall in 2020.},
