Sélection génétique des variétés originelles d’Arménie, berceau de la viticulture mondiale

Abstract

L’Arménie, petit pays du Caucase du sud, redécouvre son passé viticole depuis la mise à jour en 2007 de vestiges archéologiques viticoles datant de 6000 ans environ. Ces vestiges comptent parmi les plus anciens dans le monde. Malgré une grande diversité de cépages, les vignerons arméniens ne disposaient pas de collections génétiques suffisamment organisées pour produire des plants et satisfaire la demande croissante de plantation.
Les premiers travaux de prospection et de mise en collection ont débuté en 2012 et la disponibilité en greffons est maintenant suffisante pour lancer les étapes de multiplication. Les plants sont multipliés francs de pied pour les zones de montagnes ou bien greffés pour les zones de plaines.
Le présent article retrace les étapes d’un projet en cours, de sélection et de multiplication des cépages oubliés arméniens. Il recense et analyse les difficultés – techniques, humaines ou éthique – rencontrées au cours de ce projet ambitieux et unique.

Genetic selection of original varieties from Armenia, birthplace of world viticulture

Armenia, a small country in the south of the Caucasus, has been rediscovering its wine-growing past since the discovery in 2007 of archaeological wine-growing remains dating back around 8,000 years. They are among the oldest in the world. Despite a great diversity of grape varieties, armenian winegrowers did not have sufficiently organized genetic collections to produce plants and satisfy the growing demand for planting. Initial prospecting and collection work began in 2012 and the availability of grafts is now sufficient to launch the multiplication stages. The plants are propagated free of vines for mountain areas or grafted for plain areas. The proposed article traces the stages of selection and multiplication of forgotten armenian grape varieties; it highlights the difficulties – technical, human or ethical – encountered throughout this incredible project.

Genetische selektion ursprünglicher sorten aus armenien, der wiege des weltweiten weinbaus

Armenien, ein kleines land im süden des Kaukasus, entdeckt seit der entdeckung archäologischer weinbaureste, die etwa 6.000 jahre zurückreichen, im jahr 2007 seine weinbauvergangenheit wieder. Sie gehören zu den ältesten der welt. Trotz der großen vielfalt an rebsorten verfügten die armenischen winzer nicht über ausreichend organisierte genetische sammlungen, um pflanzen zu produzieren und die wachsende nachfrage nach anpflanzungen zu befriedigen. Die ersten prospektions- und sammelarbeiten begannen im jahr 2012 und die verfügbarkeit von transplantaten reicht nun aus, um die vermehrungsphasen einzuleiten. Für berggebiete werden die pflanzen rebenfrei vermehrt oder für flachlandgebiete veredelt. Der vorgeschlagene artikel zeichnet die stadien der auswahl und vermehrung vergessener armenischer rebsorten nach; es verdeutlicht die schwierigkeiten – technischer, menschlicher oder ethischer art –, auf die man bei diesem unglaublichen projekt stößt.

Pesticide – Free viticulture: towards agroecological wine-producing socio-ecosystems

Can we cultivate grapevine without pesticides? This is a huge challenge for this emblematic crop, which is one of the largest users of plant protection products. Pesticides are mainly used to protect the vine against leaf diseases (powdery mildew, mildew, black-rot), even in organic farming, which uses copper in particular. What are the research avenues that can help eliminate pesticides today?

Impact assessment of the reverse osmosis technique in wine alcohol management

Wine authenticity and composition can be influenced by a range of membrane separation processes as reverse osmosis. In the context of climate change, the natural trend is to obtain wines with higher alcoholic concentration when classical winemaking methods are employed, and this may induce alteration of typicity of wines by masking the olfactory and taste properties. This study aimed to evaluate the influence of reverse osmosis techniques used for decrease of ethanol content on the stable isotopic ratios as markers for wine authenticity characteristics.

Exploring diversified service offerings in the Spanish wine industry

The spanish wine industry stands at a crossroads, transitioning from a traditional emphasis on wine production to a landscape increasingly characterized by diversified service offerings. This paper delves into the nuances of servitization within spanish wineries, investigating the determinants of servitization and the impact of these diversified services on revenue streams. The paper posits hypotheses concerning the influence of various factors, such as winery size, location, market orientation, ownership structure, market competition, regulatory environment, market demand, firm capabilities, owner characteristics, and firm age, on the adoption of diversified service offerings in spanish wineries. The methodology involves comprehensive regression analysis to unravel the drivers of servitization within this context.

Genomic comparison on O. oeni: can l. hilgardii be a novel starter culture in malolactic fermentation?

Malolactic fermentation (MLF) the microbial bioconversion of L-malic acid into L-lactic acid, is a pivotal metabolic process that holds fundamental significance for the quality and organoleptic characteristics of some wines. Oenococcus oeni is considered to be the main player in this conversion, and it is globally used as a starter culture for mlf thanks to his capacity to tolerate the harsh wine environment.

Un jour, l’AOD (Appellation d’Origine viticole Durable), fusion de l’origine et de la durabilité

The evolution of wine quality issues is historically expressed by the passage from wine quality (what is a wine?) to wine quality (what is a good wine?). Perhaps the next question could be: what is a good sustainable wine? To contribute to reflection on this theme, it may be worthwhile to undertake an exercise in prospective fiction, which we have identified in the hypothesis of the AOD, the “appellation d’origine durable”, a scenario we will develop in the light of developments in the wine industry and the regulation on geographical indications.
