Nitrogen composition on grapevines has a direct effect on the quality of wines since it
contributes to develop certain volatile compounds and assists in the correct kinetics of alcoholic
fermentation. Several strategies can be used to ensure nitrogen content in grapes and one of them
could be the use of elicitors such as methyl jasmonate. The use of this elicitor has been proven to
be efficient in the production of secondary metabolites which increases the quality of wines, but
its use also has some drawbacks such as its low water solubility, high volatility, and its expensive
cost. This study observes the impact on the amino acid and ammonium composition of must
and wine of Monastrell grapes that have been treated with methyl jasmonate (MeJ) and methyl
jasmonate n-doped calcium phosphate nanoparticles (MeJ-ACP). The first objective of this study was
to compare the effect of these treatments to determine if the nitrogenous composition of the berries
and wines increased. The second aim was to determine if the nanoparticle treatments showed similar
effects to conventional treatments so that the ones which are more efficient and sustainable from
an agricultural point of view can be selected. The results showed how both treatments increased
amino acid composition in grapes and wines during two consecutive seasons and as well as the use
of MeJ-ACP showed better results compared to MeJ despite using less quantity (1 mM compared to
10 mM typically). So, this application form of MeJ could be used as an alternative in order to carry
out a more efficient and sustainable agriculture.
