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.

Energy optimization of the Charmat-Martinotti refermentation process

The european union has estimated that energy consumption for wine production is about 1,750 million kwh per year, of which 500 million kwh is attributable to italy. In recent years, Italy has emerged as the world’s leading wine producer with about 50 million hectoliters per year. About 20 percent (9.8 million hectoliters) of Italian wine is marketed after refermentation according to the Charmat-Martinotti method.

Developing a multi-hazard risk index-based insurance for viticulture under climate change

Climate change is increasing the frequency and severity of environmental hazards (e.g., prolonged drought), and even non-extreme climate events (e.g., a period of slightly warmer temperatures) can lead to extreme impacts when they occur simultaneously with other (non-extreme) events.

New highlights of polyphenols from red wine to counteract ocular degenerative diseases

More recently, studies have shown that polyphenols could also prevent or improve vision in patients with ocular diseases and especially age-related macular degeneration (AMD) which is an eye disease characterized by damage to the central part of the retina, the macula, and that affects millions of people worldwide. Despite therapeutic advances thanks to the use of anti-vascular endothelial growth factor (VEGF), many resistance mechanisms have been found to accentuate the visual deficit.

Oenological potential of wines and agronomical characterisation of grapes from five white resistant Italian varieties at Serra Gaúcha, Southern Brazil

Rio grande do sul is the main grape producing state in Brazil, with the largest wine-growing area, responsible by 90% of the national production of wines and grape juices. Serra Gaúcha is the main vitivinicultural region, where around 15% of the area is destined to produce wines from vitis vinifera L. grapes. This region presents high rainfall during the grape maturation cycle, a factor that leads to great risk of attacks by fungal pathogens. the use of resistant varieties can reduce the cost and quantity of spraying, improving wine quality, focusing on a sustainable vitiviniculture.
