Establishment of a geodatabase ‘for the characterization of the viticultural “terroirs” of “canton de Vaud” (Switzerland)

Abstract

[English version below]

La caractérisation objective des terroirs viticoles est nécessaire pour mieux comprendre les relations existantes entre les sols, la plante et la qualité de la production vinicole. Dans le cadre d’une recherche sur les terroirs viticoles du canton de Vaud – Suisse, un géorépertoire pédologique et agronomique a été conçu et réalisé. Son objectif est d’offrir une structure d’accueil et de traitement des données pédologiques et agronomiques récoltées sur le terrain. C’est un outil de saisie et d’exploitation, qui facilite la caractérisation des sols viticoles et la mise en valeur des données agronomiques. Couplé à un système d’information géographique, il permet d’en faire la synthèse et l’interprétation. Toutes les données relatives aux vignobles sont ainsi centralisées. La base de données réalisée fonctionne sur les logiciels couplés Access et Maplnfo. Ce couplage de la base- avec un système d’information géographique (SIG) permet de confronter les données pédologiques et agronomiques à celles du microclimat et d’en déduire finalement les unités terroirs recherchées.

The objective characterization of the viticultural “terroirs” is necessary in order to better understand the relationships between soils, plants and wine production quality. As part of a research on the viticultural “terroirs” of “canton de Vaud” – Switzerland, a pedological and agronomical geodatabase was designed and realized. Its purpose is to offer a structure that can store and treat the pedological and agronomical data collected in the field. This tool allows to capture and analyse information in order to facilitate the characterization of viticultural soils and the exploitation of agronomical data. All the vineyard data can be summarized and interpreted with one database, coupled with a Geographic Information System (GIS). The realized database works with Access and Mapinfo connected together. The coupling of the database with a geographic information system allows to put together pedological, agronomical and microclimatic data and analyse them to deduce “terroirs” unities.

Reconstructing ancient microbial fermentation genomes from the wine residues of Herod, Roman king of Judea

The fortress of the Herodium, built towards the end of the first century BCE/ante Cristo, on the orders of Herod the Great, Roman client king of Judea, attests the expansion of Roman influence in the eastern Mediterranean. During archaeological excavations of the Herodium in 2017[1], a winery was discovered on the ground floor of the palace, with an assortment of clay vessels in situ, including large dolia – clay fermentation vessels each capable of fermenting up to 300-400 L of wine. Thanks to the recent progresses in the field of paleogenomics[2], we could analyse the organic material consistent with grape pomace at the bottom of these vessels, by extracting and sequencing the DNA using shotgun metagenomics and targeted capture, aiming for enrichment of DNA from fermentation associated microbes.

Impact of monopolar and bipolar pulsed electric fields on the quality of Tinta Roriz wines

Pulsed electric fields (pef) technology holds significant promise for the agrifood industry, considering the capacity of inducing cell electroporation, due to the disruption of cellular membranes. Pef-induced permeabilization is dependent of the chosen treatment protocol (i.e. Pulse shape, electrical field strength, specific energy) and of the matrix’s characteristics (i.e. Cell radii and size, ph, electrical conductivity).

Investigation on the potentiality of a biostimulant by Fabaceae tissues and rich in triacontanol to enhance grapevine resilience under drought stress

The primary objective of this research was to investigate the potential benefits of a Fabaceae-based product rich in triacontanol (a long-chain alcohol) applied to Vitis vinifera cv. Merlot, on key physiological and productive parameters of grapevines under controlled water stress conditions.

Coping with extreme climatic events: some lessons from recent work on grapevine under heat peak

Climate change critically challenges viticulture. Among other threats, extreme and increasingly frequent heatwaves cause irreversible burns on leaves and bunches. A series of observations and experiments was conducted to better understand how leaf burns originate and whether genetics or management practices can mitigate them. In 2019, a panel of 279 potted cultivars of Vitis vinifera L. grown outdoors suffered a heat peak and a genetic origin of leaf burn variability was demonstrated. To deeper explore this variability, fourteen cultivars were selected for their contrasting responses to high temperatures, and detached leaves were submitted to a controlled increase in temperature up to 50 °C in a growth chamber.

Cascading effects of spring weather conditions into grape berry ripening

The effects of climate change on viticulture are complex due to interactions among factors and cascading effects.
