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.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
