Irrigation and terroir: two opposite concepts? Point of view of international experts and french consumers

Abstract

At long term, qualitative irrigation seems to be the most systematic, if not the best, cultural practice for dealing with climate change and yield increases without decrease grape quality. Given this backdrop, the acceptance or irrigation within the frameworks of the terroir definition takes a central place. Consistently, the objective of this work is to evaluate this compatibility. Since irrigation is basically a social practice, it is important to understand it from a sociological point of view.

To meet this commitment, a qualitative questionnaire was implemented: standard personal interviews with no frequency (subject surveyed once) with a multi-topic research (omnibus research). 18 participants to the 19th GiESCO Meeting were selected as participants to the questionnaire. In a second instance, a quantitative questionnaire was evaluated: depth or intensive questionnaire with close-ended questions. In parallel, 512 French wine consumers participate to an Internet survey. This way, subject was approached from a twofold perspective: qualified researchers and French wine regular consumers.

Results show that surveyed expert seems to agree (in 63% of cases) with the idea of not changing a terroir by adding water under a controlled management of the water status in the vine. Level of agreement seems to be related with expert’s provenance and therefore expert’s observations in their local weather. Finally, concerning consumer’s approach, the level of implication in wine seems to play a role in accepting irrigation; consumers not implicated on wine don’t have a formed opinion whereas implicated consumers showed both; for and against a reasoned irrigation as a tool to deal against climate change. Moreover, within qualified consumers, age could serve for explaining the acceptance of irrigation: young (≤35 years old) and medium consumers (from 36 to 64 years old) were more likely to accept irrigation and a different grape variety to preserve wine quality.

Evaluation of state of vineyards and characterization of vineyard sites of the integrated area of Tokaj Kereskedőház ltd. in Tokaj region

The Tokaj Kereskedőház Ltd. is the only state owned winery in Hungary. The company is integrating grapes for wine production from 1100 hectares of vineyard, which consist of 3500 parcels with average size of 0,3 hectares, owned by about 500 families of the region. The vineyards are unevenly spread in total 27 village of Tokaj region.

Training system and its influence on iso-anisohydric behavior of cv. Syrah

Water use efficiency is one of the most valued objectives in vine growing in mediterranean climates (de la fuente et al., 2015). Due to this, the grape growers provide different adaptation strategies according to their efficient consumption against the presumable water deficit generated under these environmental conditions. The use of non-positioned shoot systems (like sprawl, bush, etc.) Can help to achieve this objective.

Evaluation of biodegradable mulch for weed control with focus on vineyard performance

Context and Purpose of the Study. The use of herbicides and mechanical soil tillage, particularly on steep slopes, poses significant ecological challenges, including soil compaction and erosion.

Heatwaves impacts on grapevine physiology, berry chemistry & wine quality

Climate change impacts on both yields and quality have increased over the past decades, with the effects of extreme climate events having the most dramatic and obvious impacts. Increasing length and intensity of heatwaves associated with increased water stress necessitates a reevaluation of climate change responses of grapevine and, ultimately, a reconsideration of vineyard management practices under future conditions. Here we summarize results from a three-year field trial manipulating irrigation prior to and during heatwave events to assess impacts of water application rates on vine health and physiology, berry chemistry, and wine quality. We also highlight potential mitigation strategies for extreme heat, both in terms of water application, as well as other cultural practices that could be widely applicable.

Enhancing plant defense: carbon dots for efficient spray-induced gene silencing 

Ectopic RNA application for plant defense faces challenges in tree crops, including size, diffusion, and stability of active compounds such as ribonucleoproteins and nucleic acids. While existing strategies involve expressing dsRNA in transgenic plants targeting pathogens, our research strives to develop a transient RNAi system based on Spray-Induced Gene Silencing (SIGS). This approach aims to circumvent legal barriers and public concerns associated with genetically modified organisms (GMOs). Our strategy integrates SIGS with branched polyethyleneimine-functionalized Carbon Dots (bPEI-CDs) as nanocarriers, effectively addressing unique delivery challenges in plant defense as RNA stability and uptake enhancement
