Zoning, environment, and landscape: historic and perspective

Abstract

[English version below]

Dans une approche globale, nous proposons la définition suivante du zonage : “représentation cartographique associée à une sectorisation du territoire en zones unitaires homogènes à partir de facteurs discriminants établis sur la base d’indicateurs quantifiables et d’avis d’experts”. La première application de cette méthode a porté sur la caractérisation du terroir en liaison avec les aspects qualitatifs des vins. Il est également possible d’envisager d’appliquer cette démarche dans les stratégies environnementales et paysagères liées aux approches territoriales et aux pratiques viticoles. Cette méthode peut servir de base dans la mise en œuvre des outils financiers associés aux mesures environnementales (CTE, aides spécifiques). Le zonage est déjà utilisé sur le plan législatif vis-à-vis de l’utilisation des amendements azotés (zones vulnérables) et de la protection des espèces (biotope, natura 2000). Dans le cadre d’une application spécifique à la viticulture associé à la multifonctionnalité du terroir, plusieurs axes peuvent être envisagés:
– Vulnérabilité des sols au transfert de polluants,
– Cartes d’érosion et d’aptitudes à l’enherbement
– Caractérisation microbiologique des sols,
– Protection des paysages,
– Application sectorisée des modèles de prévision des maladies.

In a global approach, we propose the following definition as regards zoning: “cartographic representation associated to a division into sectors of the territory in homogeneous unitarian zones from discriminants factors established on the basis of quantifiable indicators and of experts opinions”. The first application of this method concerned the soil characterization in contact with the qualitative wine aspects. It is also possible to intend to apply this step in the environmental and landscaped strategies bound to the territorial approaches and to the wine practices. This method can serve as base in the application of the financial tools associated to the environmental measures (CTE, specific helps). Zoning is already used on the legislative plan towards the nitrogenous amendments use (vulnerable zones) and the sorts protection (biotope, NATURA 2000). Within the framework of a specific vine growing application associated to the soil multifunctionality, several axes can be envisaged:
– Ground vulnerabilities in the pollutant transfers,
– Cards of erosion and capacities in the enherbement,
– Microbiologie characterization of grounds,
– Landscape protections,
– Sectorised application of the disease forecast models.

How can yeast modulate Divona’s aromatic profile?

Volatile thiols play a key role in the aromatic expression of white wines, contributing to notes such as passion fruit, grapefruit, and herbal nuances [1]. These compounds, present as non-volatile precursors in grapes, require enzymatic activation to be released and realize their aromatic potential.

FUNGAL DIVERSITY AND DYNAMICS IN CHAMPAGNE VINEYARDS: FROM VINE TO WINE

Champagne is a well-known wine region in Northern France with distinct terroirs and three main grape varieties. As for any vineyard, wine quality is highly linked to the microbiological characteristics of the raw materials. However, Champagne grape microbiota, especially its fungal component, has yet to be fully characterized. Our study focused on describing this mycobiota, from vine to small scale model wine, for the two main Champagne grape varieties, Pinot Noir and Meunier, using complementary cultural and omics approaches.

Use of Fourier Transform Infrared Spectroscopy (FTIR) to rapidly verify the botanical authenticity of gum arabic

Gum arabic is composed of a polysaccharide rich in galactose and arabinose along with a small protein fraction [1, 2], which gives its stabilizing power with respect to the coloring substances or tartaric precipitation of bottled wine. It is a gummy exudation from Acacia trees; the products used in enology have two possible botanical origins, i.e. Acacia seyal and Acacia senegal, with different chemical-physical features and consequently different technological effects on wines. The aim of this work is to evaluate the feasibility of discrimination of commercial gums Arabic between their two different sources, on the basis of the absorption of the Fourier Transform Infrared (FT-IR) spectra of their aqueous solutions, in order to propose an extremely rapid and cost-saving method for quality control laboratories.

Hemisynthesis, NMR Characterization and UHPLC-Q-Orbitrap /MS² identification of (+)-Catechin oxidation products in red wines and grape seed extracts

(+)-Catechin—laccase oxidation dimeric standards were hemi-synthesized using laccase from Trametes versicolor in a water-ethanol solution at pH 3.6.

Exploring the mechanisms of grapevine single berry development and ripening

The strategy of single berry phenotyping is a recently rediscovered research tool that has gained great attention. The latest studies have indicated that previous physiological models based on pooling asynchronous populations of berries provided biased or blurred information on berry development key players. The possibility of monitoring and sampling single synchronized berries to study their development sequentially has opened new lines of research aimed at unraveling the genes that regulate grapevine fruit development. This study aimed to decipher the gene pathways responsible for the activation/deactivation of physiological processes involved in the green phase of growth, the onset of ripening, and the second growth phase.
