Effect of foliar application of Ca, Si and their combination on grape volatile composition

Abstract

Calcium (Ca) is an important nutrient for plants which plays key signaling and structural roles. It has been observed that exogenous Ca application favors the pectin accumulation and inhibition of polygalacturonase enzymes, minimizing fruit spoilage. Silicon (Si) is a non-essential element which has been found to be beneficial for improving crop yield and quality, as well as plant tolerance to diverse abiotic and biotic stress factors. The effect of Si supply to grapevine has been assessed in few investigations, which reported positive changes in grape quality and must composition. The aim of this work was to evaluate the influence of Ca and Si foliar treatments, applied either as single elements or in combination, on volatile composition of Tempranillo grapes. All treatments were applied twice, at veraison and one week later. The foliar applications were performed in triplicate, in a randomized block design. The volatile composition was determined in the musts by headspace solid-phase microextraction (HS-SPME) and subsequent analysis by GC-MS. Tempranillo is a neutral aromatic variety, for this reason, on this work we have focused on terpenoids and C13 norisoprenoids, the two families most important regarding varietal aromas. Foliar application of Ca and Ca+Si enhanced p-cymene, geraniol, neral, and total terpenoids content in must with respect to control one. Ca+Si foliar treatment also improved limonene, α-terpineol, linalool, and nerol concentration in comparison with control must. Regarding C13 norisoprenoids, Ca+Si foliar application was the only treatment that increased (E)-β-damascenone, (Z)-β-damascenone, β-cyclocitral, TDN, methyl jasmonate, and total C13norisoprenoids with respect control must. Therefore, Ca+Si foliar application is a good tool to improve the varietal aromatic quality of Tempranillo grapes and it is economically feasible.

Grapevine adaptation to drought and resistance to Neofusicoccum parvum, causal agent of Botryosphaeria dieback

The sustainability of viticulture in response to climate change has been addressed mainly considering agronomic impacts, such as water management and diseases, either separately or together.
In grapevines, there is strong evidence that different genotypes respond differently to biotic and abiotic stresses. A screening was conducted on various local cultivars in response to drought and Neofusicoum parvum infection aiming to evaluate their susceptibility to abiotic stress and resistance to fungal diseases.

Late winter pruning induces a maturity delay under temperature-increased conditions in cv. Merlot from Chile

Chile is considered vulnerable to climate change; and these phenomena affect several mechanisms in the grape physiology and quality. The global temperature increase affects sugar contents, organic acids, and phenolic compounds in grapes, producing an imbalance maturity. In this sense, an alternative to reduce the impact is to perform pruning after vine budburst, known as “Late Pruning” (LP).

Optimization of the ripening time of new varieties descendants of Monastrell

Given the impact of climate change on viticulture in the Region of Murcia, this paper attempts to expose the possibility of using genetic improvement as a dilemma that allows access to new descendant varieties of the autochthonous variety Monastrell crossed with varieties such as Syrah and Cabernet. Sauvignon, thus obtaining hybrids (Gebas and Myrtia). In it, the chromatic parameters and the phenolic profile of the new varieties will be compared with those obtained by the Monastrell variety at two moments during maturation (12 and 14 º Baumé), to check if the results would allow earlier harvests in these new varieties thus avoiding the decoupling between phenolic and technological maturity, while improving the quality of grapes and wines.

Irrigation frequency in four grapevine red varieties in Spain. Effect on must volatile composition

The irrigation water management in the vineyard is a crucial aspect to obtain sustainable quality production over time. Previous studies have set the water requirements to be applied in the vineyard at 30 % of the reference evapotranspiration (ET0), although there are no studies that settle the effects of the frequency of irrigation application on red varieties in Spain. The present study contemplates the application of deficit irrigation (30 % ET0) applying a weekly dose in a single irrigation (T07) or in two irrigation events (T03) per week. The study has been carried out in 2021-2022 with four red varieties in different Spanish wine regions: Garnacha Tinta (Badajoz), Tempranillo (Valladolid), Syrah (Albacete) and Mencía (Lugo). The effects of irrigation frequency on must volatile composition have been evaluated through GC-MS.
