Influence of edapho-climatic factors on grape quality in Conca de Barberà vineyards (Catalonia, Spain)

Abstract

Soil and climate of 3 vineyards have been characterised in order to determine their influence on grape quality. These vineyards are located in Conca de Barberà (Catalonia, NE Spain) and belong to Cabernet sauvignon and Grenache noir cultivars. All 3 plots are very close, so only interannual climatic data of the nearest meteorological station have been considered. Different climatic indexes have been calculated from climatic data. The studied vineyard soils present very different textural classes and rock fragment contents, causing very distinct soil water regimes. Besides determining chemical and physical properties of soils, the soil water availability has been characterised using capacitance sensors at different depths for the period from 2003 to 2005. Data of quality of grapes were available. Statistical techniques, concretely Principal Component Analysis and Multiple Regression Analysis, have been used to relate edapho-climatic factors to grape quality. The results show that edapho-climatic data have a high power of estimation on grape quality (generally, R2 higher than 0.75). Climate appeared to be the most influencing factor, followed by water availability. Soil had also influence on grape yield and some must data.

Prise en compte de la notion de terroir dans les AOC en France : Aspects Culturels

“The vine and the wine are great mysteries. Only the vine makes us intelligible what is the true flavor of the earth”. Colette. The notion of terroir has always been the basis of the notion of AOC from which it is inseparable. It is moreover the definition of the production zone which was at the start of the attempts to set up the designation of origin, at the beginning of the century, after the phylloxera crisis.

Lipids at the crossroads of protection: lipid signalling in grapevine defence mechanisms

Understanding grapevine molecular processes and the underlying defence responses is vital for developing sustainable disease control strategies. Lipid signalling pathways, involving the synthesis and degradation of lipid molecules, have emerged as a key regulator in plant defence against pathogens. This study aims to elucidate the role of fatty acids and lipid signalling in grapevine’s defence response to P. viticola infection. The expression of lipid metabolism-related as well as lipid signalling genes was analysed, by qPCR, in three grapevine genotypes: Chardonnay (susceptible), Regent (tolerant) with Rpv3-1 resistance loci, and Sauvignac (resistant) harbouring a pyramid of Rpv12 and Rpv3-1 resistance loci.

NIR based sensometric approach for consumer preference evaluation

Climate change has had a global impact on grape production, and as a result, developing table grape varieties that can withstand climate-related threats has become a significant goal. However, it is equally important to ensure that these new grape varieties meet the preferences of consumers. To achieve this goal, a procedure has been developed that combines sensory analysis with spectroscopic data collected in the NIR region. Each sample was analyzed using both traditional analytical techniques and non-destructive NIR spectroscopy.
