The« Sigales’ method »

Abstract

Le comportement de la vigne est étroitement lié aux propriétés hydriques des sols surtout dans leurs parties profondes. Cette importance majeure des variables les moins accessibles à l’observation rend difficile la réalisation de cartes de sols pertinentes.
Connaissance et expérience du vigneron sont extrêmement riches d’informations.
C’est pourquoi il est placé au cœur de la réflexion, de façon à ce que les compétences scientifiques et techniques des experts et les observations pratiques des hommes de terrain s’enrichissent mutuellement.
Cette « méthode » est basée sur un système de réunions, de formation, qui permet une validation systématique en salle et sur le terrain des hypothèses de spatialisation cartographique.
Ainsi, avec des moyens raisonnables, deux buts sont atteints : la création de documents cartographiques validés et adaptés et la formation des vignerons, acteurs principaux de la filière viticole.

The behaviour of the grape plant is directly related to the availability of water in the deep and very deep ground layers. This major influence of the less accessible variables makes creation of relevant soil maps difficult.
The knowledge and the experience of the wine grower are the keys to gather meaningful information.
In the « Sigales’method » we try first to give sense to the observations of the wine growers and of their technical team by collective work. Then we draw more accurate maps that ve validate outside with them.
With affordable efforts we achieve two goals : validated and accepted maps and educated wine growers.

Convergence and divergence in chemical and sensory profiles of disease-resistant and Vitis vinifera white wines from South Tyrol: addressing strategies for market adoption

This study investigates the chemical and sensory profiles of white wines produced from disease-resistant hybrid grape cultivars (DRHGCs) compared to traditional Vitis vinifera L. cultivars in South Tyrol, Italy.

Effect of drought on grapevine wood fungal pathogen communities using a metatranscriptomics approach

Crops are facing increasing biotic and abiotic stress pressures due to global changes. However, trade-off mechanisms between these stresses and the underlying physiological processes are still poorly understood, especially in perennial crop species. To better understand these trade-offs, we studied the effect of drought on grapevine (Vitis vinifera) physiology and esca-related wood fungal communities. Esca is a vascular disease caused by a community of wood-infecting pathogenic fungi, and characterized by trunk necrosis, leaf scorch symptoms, yield losses, and mortality.

Unveiling the impact of seasonal weather and fungicide spraying on vineyard autochthonous yeast populations: implications for Riesling wine quality

Fungicide spraying is a common viticultural practice that occurs throughout the growth season that protects developing vines and bunches against diseases caused by fungi or oomycetes.

Catechins, NMR, Huntington’s disease, protein aggregation modulation

Catechins, a subclass of flavonoids widely found in plants and plant-based foods and beverages such as wine and tea, not only exhibit significant antioxidant properties [1], as extensively documented in the literature, but can also inhibit amyloid protein aggregation [2], a key process implicated in the onset of neurodegenerative diseases such as Parkinson’s, Alzheimer’s, and Huntington’s.
