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.

INTEGRAPE guidelines and tools: an effort of COST Action CA17111

INTEGRAPE was a European interdisciplinary network for “data integration to maximize the power of omics for grapevine improvement” (CA17111, https://integrape.eu/), funded by the European COST Association from September 2018 to 2022. This Action successfully developed guidelines and tools for data management and promoted the best practices in grapevine omics studies with a holistic future vision of: “Imagine having all data on grapevine accessible in a single place”.

Characterization of a Sémillon clonal population: exploring genetic diversity, metabolomic profiles, and phenotypic variations

Sémillon is a cultivated grape variety known for contributing to dry and sweet white wine production. However, only seven approved clones have been officially recognized in France[1]. In this study, we aimed to characterize the genetic diversity and metabolomic profiles of a Sémillon clonal population, shedding light on the potential variations within this important grape variety.

Foliar application of urea improved the nitrogen composition of Chenin grapes

The nitrogen composition of the grapes directly affects the developments of alcoholic fermentation and influences the final aromatic composition of the wines. The aim of this study was to determine the effect and efficiency of foliar applications of urea on the nitrogen composition of grapes. This study was carried out during 2023 vintage and in the Chenin vineyard located in Estacion Experimental Mendoza (Argentina). Three urea concentrations 3, 6 and 9 Kg N/ha (C1, C2, and C3, respectively) and control (T) were applied in this vineyard at veraison. In all solutions were added 1ml/l of Tween 80 ® surfactant.

Effects of laccase from Botrytis cinerea on the oxidative degradation kinetics of the five natural grape anthocyanins

Enzymatic browning[1] is an oxidation process that occurs in many foods that increases the brown colour[2]. This problem is especially harmful in the wine industry[3]. especially when the grapes are infected by grey rot since this fung release the oxidative enzyme laccase[4]. In the particular case of red wines, the presence of laccase implies the deterioration of the red colour and can even cause the precipitation of the coloring matter (oxidasic haze)[5].

Metabolomic insights into wine’s sensory identity: unveiling climate-driven changes in aroma composition

Wine, a sensitive and intricate agricultural product, is being affected by climate change, which accelerates grapevine phenological stages and alters grape composition and ripening. This influences the synthesis of key aroma compounds, shaping wine’s sensory attributes [1]. The complex aroma profile, resulting from compound interactions, presents a metabolomics challenge to identify these indicators and their environmental change responses, which is being addressed using diverse analytical techniques.
