Methyl Jasmonate Versus Nano-Methyl Jasmonate: Effect On The Stilbene Content In Monastrell Variety

Abstract

Stilbenes, a kind of non-flavonoid phenolic compounds, have been reported to be responsible for various beneficial effects. Their biological properties include antibacterial and antifungal effects, as well as cardioprotective, neuroprotective and anticancer actions (Guerrero et al. 2009).Several strategies can be used to increase stilbene 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 (Gil-Muñoz et al. 2021).
This study observes the impact on stiblene composition of must and wine of Monastrell grapes that have been treated with methyl jasmonate 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 stilbene composition of the berries and wines increased. The second aim was to determine if the nanoparticle treatments showed similar effects to way treatments so that the ones which are more efficient and sustainable from an agricultural point of view can be selected.
The experiments were conducted in a randomized block design during three consecutive seasons (2019-2021), in which all treatments were applied to three replicates, using 10 vines for each replication. Two foliar treatments were applied to the plants in spray form as a water suspension of MeJ 10 mM (methyl jasmonate and a water suspension of MeJ-ACP 1 mM (Mej-doped calcium phosphate nanoparticles) at veraison. Approximately 200 mL of the product was applied to each plant prepared with Tween 80 (Sigma Aldrich, St. Louis, MO, USA) as the wetting agent (0.1% v/v). Control plants were sprayed with aqueous solution of Tween 80 alone. For all treatments, a second application was performed 7 days after the first. Stilbenes were analyzed according to the methodology shown in Gil-Muñoz et al. (2017).
The results showed how, in general both treatments are able to increase stilbene composition in grapes and wines although depending on the season these results were more evident. As well, the the use of MeJ-ACP showed better results compared to MeJ despite using less quantity (1 mM compared to 10 mM typically) in wines in 2019 and 2021. So, this application form of MeJ could be used as an alternative in order to carry out a more efficient and sustainable agriculture and improve the wine quality.

From plant water status to wine flavonoid composition: a precision viticulture approach in a Sonoma county vineyard

Plant water status of grapevine plays a critical role in affecting berry and final wine chemical composition. The environmental variabilities existing in vineyard system have significant impacts on plant water status, but it is challenging to individualize environmental factors from the temporal and spatial variabilities in vineyard. Therefore, there is need to monitor the ecophysical variation through utilizing precision viticulture tools in order to minimize the separation in berry composition. This study aims at delineating vineyard into different management zones based on plant water status explained by soil texture, and utilize differential harvest to equilibrate the final berry and wine composition.

Exploring the impact of yeast derivatives on aromatic and sensory profiles of white and red wines: a multifactorial analysis

Specific inactivated yeast derivatives (SYDS) are obtained from s. cerevisiae yeasts by various processes (thermal, mechanical, and enzymatic) and have diverse oenological applications to improve wine quality. However, different impacts on wine sensory and aromas were reported, depending on syds types and fractions, wine matrices, and experimental settings. Few works have examined the impact of SYDS on aromas considering also those on wine macromolecules influencing organoleptic properties.

The environmental footprint of selected vineyard management practices: A case study from Logroño (La Rioja) Spain

Viticulture is globally important for socioeconomic and environmental reasons. The EU is globally leading grape and wine production, and Spain is among the top grape and wine producers. As climate change affects viticulture, mitigation and adaptation are crucial for protecting grape production. In this research work, data on viticultural management practices such as soil cultivation, irrigation, energy, machinery, plant protection and the use of fertilizers from vineyards located in Logroño (La Rioja) have been obtained.
