“…The synthesis of MeJ-ACP nanoparticles was carried out through a simple and eco-friendly method previously reported [ 30 ]. Briefly, it consisted of mixing 2 L of an aqueous solution (i) containing 0.2 mol L −1 Ca (NO 3 ) 2 , 0.2 mol L −1 sodium citrate (Na 3 Cit) with an equal volume of solution (ii) containing 0.12 mol L −1 K 2 HPO 4 and 0.1 mol L −1 Na 2 CO 3 .…”

“…After 24 h under agitation, MeJ-ACP nanoparticles were collected by centrifugation (3700 rpm, 15 min, 4 °C). MeJ loading was estimated by UV-Vis spectroscopy, as previously described [ 30 ]. Nanoparticles contained 6% w / w of MeJ.…”

“…Several nanoparticle types are starting to be used in agriculture, but the use of calcium phosphate nanoparticles in crops, in order to use less pesticides and increases their quality, has received much less attention. Very recently, we developed nanoelicitors which consisted of amorphous calcium phosphate nanoparticles (mimicking the precursor phase of bone mineral) [ 30 ]. We demonstrated that this type of nanoparticles can retain and protect MeJ on the surface of the leaves during a longer period of time.…”

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.

“…12 There are numerous studies on the effect of the application of elicitors in the field, specifically in the vineyard; two examples of such compounds are methyl jasmonate (MeJ) and benzothiadiazole (BTH; benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester), which are effective in increasing concentration of aromas, nitrogen compounds, and phenolic compounds in different varieties of wine grapes. [15][16][17][18][19][20] MeJ has been mainly implicated as a mediator in plant responses triggered by wounding and insect feeding and is involved in pathogen resistance. 21 BTH is a synthetic functional analogue of the plant endogenous hormone-like compound salicylic acid, which induces defence genes leading to systemic acquired resistance and an increase in phenolic production.…”

BACKGROUND Proanthocyanidins (PAs) are phenolic compounds present in skins and seeds of wine grapes and have great implications for plant physiology and wine quality. There are several strategies to increase PA concentration, such as application of elicitors methyl jasmonate (MeJ) and benzothiadiazole (BTH), compounds that can stimulate defence responses like phenolic compound biosynthesis in wine grapes, which have been applied mainly at veraison (beginning of ripening). We recently evaluated the application of MeJ and BTH on Vitis vinifera cv. Monastrell grapes during veraison and mid‐ripening (3 weeks after veraison). Grapes treated at mid‐ripening showed higher anthocyanin concentrations than those at veraison. In this trial, over two seasons, we evaluated whether time of application (veraison or mid‐ripening) of MeJ and BTH on ‘Monastrell’ grapes is a determining factor in the biosynthesis and composition of PAs in grapes and their subsequent release into wines. RESULTS Application of elicitors at different ripening times produced significant differences in the PAs of ‘Monastrell’ grapes, since those treated at mid‐ripening recorded a higher PAs concentration in skin and seeds, and then in the wines produced, compared to grapes treated at veraison. CONCLUSION Results suggest that despite different environmental conditions endured in each of the two seasons evaluated, application of elicitors at mid‐ripening of Monastrell grapes could be used to harvest grapes with higher PA concentration, increasing the functional value of the wines, without altering their organoleptic quality. © 2022 Society of Chemical Industry.

BACKGROUNDElicitors induce defense mechanisms triggering the synthesis of secondary metabolites. Irrigation has implications for a more sustainable viticulture and for grape composition. The aim was to investigate the influence of foliar applications of amorphous calcium phosphate (ACP) nanoparticles and ACP doped with methyl jasmonate (ACP‐MeJ), as elicitor, under rainfed and regulated deficit irrigation (RDI) grapevines, on grape aroma composition during 2019 and 2020.RESULTSIn both seasons, nearly all terpenoids, C13 norisoprenoids, benzenoid compounds and alcohols increased with ACP‐MeJ under the RDI regimen. In 2019, under the rainfed regime, ACP treatments increased limonene, p‐cymene, α‐terpineol, TDN, 2‐ethyl‐1‐hexanol, (E,E)‐2,4‐heptadienal and methyl jasmonate concentration respect to control. In 2020, rainfed regime treated with ACP‐MeJ, only increased nonanoic acid content. Grape volatile compounds were most influenced by season and watering status, while the foliar application mainly affected the terpenoids.CONCLUSIONA RDI regime combined with the elicitor ACP‐MeJ application could improve the synthesis of certain important volatile compounds, such as p‐cymene, linalool, α‐terpineol, geranyl acetone, β‐ionone, 2‐phenylethanol, benzyl alcohol and nonanoic acid in Monastrell grapes.This article is protected by copyright.
