Which risk assessment of water quality in pdo vineyards in Burgundy (France)?

Abstract

To meet the demand of assessment tool of water managers we adapted to the vine production the INDIGO® method to developed initially for arable farming at the field scale. This article aims to assess the quality of water in Burgundy areas where viticulture is pointed out to downgrade quality of surface water and groundwater. Knowing production practices at field scale allow locating where changes of production practices could upgrade surface water and groundwater quality.

INDIGO® I-phy indicator of sustainability were built based on different aggregation methods of winegrowers practices and field characteristics with a mark between 0 (risk maximum) and 10 (no risk) and 7 is the acceptable limit for environment. Water modules of I-Phy were tested in three PDO vineyards in Burgundy, in two climate conditions (2011 and 2012). Calculations have been done for I-phy indicator and groundwater (ESO) and surface water (ESU) modules on 32 fields, equally distributed in very high quality and regular quality PDO areas and in integrated or organic/biodynamic systems.

The results lead us to assess water pollution risk in different vineyard conditions. Global risk for environment is low: a very few fields under 7: 6 in 2011 and 7 in 2012 which one field under 3. Most of the global risky fields are in PDO-Rully area.

ESO risk is higher than ESU risk for almost all the fields in the 3 PDO areas. There are 4 reasons explaining the results: (i) active ingredients in used pesticides, even for organic. Active ingredient are classed R50/53. (ii) rate of the active ingredient. (iii) vine growing period of application. (iv) at least, the slope of the fields, the length of the rows, the proximity of a river and the rate of clay in the soil are also important risk factors for ESO risk. Winegrowers in Burgundy are aware of ESO risk and already manage to reduce rate of pesticides and chose the right moment to treat the vine according to the field characteristics.

Accumulation of deleterious mutations in grapevine and its relationship with traits of interest for wine production and resilience

Deleterious mutations that severely reduce population fitness are rapidly removed from the gene pool by purifying selection. However, evolutionary drivers such as genetic drift brought about by demographic bottlenecks may comprise its efficacy by allowing deleterious mutations to accumulate, thereby limiting the adaptive potential of populations. Moreover, positive selection can hitchhike mildly deleterious mutations due to linkage caused by lack of recombination. Similarly, in the context of species domestication, artificial selection mimics these evolutionary processes, which can have undesirable consequences for production and resilience. In this study, we evaluated the extent of the accumulation of deleterious mutations and the magnitude of their effects (also known as genetic load) at the whole-genome scale for ca.

Saccharomyces cerevisiae intraspecies differentiation by metabolomic signature and sensory patterns in wine

AIM: The composition and quality of wine are directly linked to microorganisms involved in the alcoholic fermentation. Several studies have been conducted on the impact of Saccharomyces cerevisiae on volatile compounds composition after fermentation. However, if different studies have dealt with combined sensory and volatiles analyses, few works have compared so far the impact of distinct yeast strains on the global metabolome of the wine.

THE ODORIFEROUS VOLATILE CHEMICALS BEHIND THE OXIDATIVE AROMA DEGRADATION OF SPANISH RED WINES

It is a well-established fact that premature oxidation is noxious for wine aromatic quality and longevity. Although some oxidation-related aroma molecules have been previously identified, there are not works carrying out systematic research about the changes in the profiles of odour-active volatiles during wine oxidation.

Biomarker-based phenotyping of grapevine (vitis spp.) resistance to plasmopara viticola reveals interactions between pyramided resistance loci

Grape downy mildew, caused by plasmopara viticola, is one of the main diseases affecting viticulture worldwide and its control usually relies on frequent sprays with agrochemicals. Grapevine varieties resistant to p. Viticola represent an effective solution to control downy mildew and reduce the environmental impact of viticulture. Loci of resistance to p. Viticola (Rpv) have been introgressed from wild vitis species and some of them, like Rpv1, Rpv3.1 and Rpv10, are currently the most utilized genetic resources in grape breeding.
