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.

Time vs drought: leaf age rather than drought drives osmotic adjustment in V. vinifera cv. Pinot Noir

Global warming and increased frequency and/or severity of drought events are among the most threatening consequences of climate change for agricultural crops. In response to drought, grapevine (as many other plants) exhibits osmotic adjustment through active accumulation of osmolytes which in turn shift the leaf turgor loss point (TLP) to more negative values, allowing to maintain stomata opened at lower water potentials1. We investigated the capacity of Pinot noir leaves to modulate their osmotic potential as a function of: (i) time (seasonal osmoregulation), (ii) growing temperatures, and (iii) drought events, to enhance comprehension of the resilience of grapevines in drought conditions. We performed trails under semi-controlled field conditions, and in two different greenhouse chambers (20/15 °C vs 25/20 °C day/night). For two consecutive vegetative seasons, grafted potted grapevines (Pinot noir/SO4) were subjected to two different water regimes for at least 30 days: well-watered (WW) and water deficit (WD).

Italy sweet revolution: how club grapes are transforming the table grape market

Italy is the leader table grape producer country in Europe and the eighth worldwide (OIV, 2021). The italian production area is sized at approximately 47,248 hectares with a production of 9.66 million quintals of grapes. Apulia and sicily are the main producing italian regions which collectively account for over the 90% of the italian production area (istat, 2022).

Effect of Yeast Derivative Products on Aroma compounds retention in model wine

For many years, enological research has developed commercial formulates of yeast derivatives as stabilizing agents and technological adjuvants in winemaking. These products are obtained from yeast by autolytic, plasmolytic, or hydrolytic processes that liberate many macromolecules from the yeast cell, principally polysaccharides and oligosaccharides and most specifically mannoproteins that are well known for their ability to improve tartaric stability and to reduce the occurrence of protein hazes (Ángeles Pozo-Bayón et al., 2009; Charpentier & Feuillat, 1992; Morata et al., 2018; Palomero et al., 2009).

The aroma diversity of italian white wines

AIM: Aroma is a key contributor to white wines sensory typicality, perceived diversity and overall preference.

Evaluation of aroma characteristics in Vitis amurensis grapes across different regions by using HS-SPME-GC/MS

Background: Aroma compounds are important secondary metabolite in grapes and play important roles in the flavor and quality of grape berries and their wines. Vitis amurensis grape belongs to the East Asian Vitis spp., with excellent cold and disease resistance, and exhibits strong brewing potential. However, it has not been effectively utilized and there is no systematic research on the aroma compounds of V. amurensis grapes.
Methods: To provide sufficient experimental evidence for the characteristic aroma of V. amurensis grape, HS-SPME-GC/MS was used to identify the aroma compounds of five V. amurensis (‘Beiguohong’, ‘Beiguolan’, ‘Shuangfeng’, ‘Shuanghong’, ‘Shuangyou’) and three interspecific hybrids (‘Beibinghong’, ‘Xuelanhong’, ‘Zuoyouhong’) grapes in Zuojia and Ji’an. The grape berries were collected at harvest in 2020, 2021 and 2022.
