Phenolic acid characterization in new varieties descended from Monastrell.

Abstract

Phenolic acids are phytochemicals that are expansively distributed in daily food intake. Phenolic acids are involved in various physiological activities, such as nutrient uptake, enzyme activity, protein synthesis, photosynthesis, and cytoskeleton structure in seeds, leaves, roots, and stems. Also exhibit antibacterial, antiviral, anticarcinogenic, anti-inflammatory, and vasodilatory activities due to their antioxidant property.
Climatic conditions are generally believed to largely determine the formation of specific wine characteristics of certain grape varieties. In addition, a continuous increase in global temperature is responsible for a significant decrease in wine quality since excessive sugar contents result in a high alcohol content, low acidity, imperfect colour and negative effects on the flavour of wine due to the uncoupling of ripening from phenolic compound production (delayed) and to technological processing (accelerated). By this reason, our research centre (IMIDA), has carried out a genetic improvement program with the Monastrell variety, in order to obtain improved and adapted varieties. In this line, Monastrell has been crossed with others such as Cabernet Sauvignon or Syrah (MC80, MC98, MS10, MC18, MC4 and MS104).
This study represents the first data of phenolic acid composition of new varieties obtained from crosses with Monastrell. Phenolic acids are divided into hydroxy-benzoic (HBA) and hydroxycinnamic (HCA). The main HBA acids present in juices and wines are protocatechuic, vanillin, gallic and syringic, and the main HCA are p-coumaric, caffeic, ferulic, and cis and trans cinnamic acid: caftaric, cutaric and fertaric.
During two consecutive seasons (2020 and 2021) the profile of phenolic acids from Monastrell and six new varieties have been studied in grapes and wines. The metabolites analysed were gallic, protocatechuic, vanillin, syringic, coumaric, caffeic, ferulic, caftaric and cutaric acids. MC80, MC98 and MS10 obtained high concentrations of these phenolic acids in their grapes and wines compared to Monastrell variety.
In short, these new varieties have higher concentrations in phenolic acids compared to Monastrell so given their potential health benefits, phenolic acids have attracted considerable research interest. Therefore, these new varieties could have an interesting point of view in human health due to their rich nutrients in their wines.

Terroir, sol et sous-sol : principes de modélisation spatiale de quelques paramètres physiques caractérisant le substrat altéré dans les régions viticoles établies sur socle ancien

For several years, the development of computer resources, and in particular of Geographic Information Systems, have allowed the emergence of a new approach to the analysis and characterization of wine-growing areas (Morlat, 1989; Laville, 1990). These methods, which make it possible to identify homogeneous areas or units of terroir, are based on crossing, statistical analysis (in particular Principal Component Analysis: PCA) and the integration of parameters describing the natural environment in which develop the vine.

Genotypic differences in early-stage root architectural traits and consequences for water uptake in three grapevine rootstocks differing in drought tolerance

Root architecture (RSA), the spatial-temporal arrangement of a root system in soil, is essential for edaphic resources acquisition by the plant, and thus contributes largely to its productivity and adaptation to environmental stresses, particularly soil water deficit. In grafted grapevine, while the degree of drought tolerance induced by the rootstock has been well documented in the vineyard, information about the underlying physiological processes, particularly at the root level, is scarce, due to the inherent difficulties in observing large root systems in situ. The aims of this study were (i) to determine the phenotypic differences in traits related to root distribution and morphology along the substrate profile in different Vitis rootstocks during early growth, (ii) to assess the plasticity of these traits to soil water deficit and (iii) to quantify their relationships with plant water uptake.

Artificial intelligence-driven classification method of grapevine phenology using conventional RGB imaging

The phenological stage of the grapevine (Vitis vinifera L.) represents a fundamental element in vineyard management, since it determines key practices such as fertilization, irrigation, phytosanitary interventions and optimal harvest time (Mullins et al., 1992).
