Climatic zoning and viticulture in Galicia (North West Spain)

Abstract

Galicia is situated in the NW of the Iberian Peninsula, just north of Portugal and so sharing a mild, maritime climate, certain vine species and a number of long-standing viticultural traditions. In Galicia about 18,000 has are dedicated to wine growing, of which roughly half (46%) correspond to the 6 DOs in the area. The Galician climate is marked by its great diversity that can be explained by the prevailing maritime and continental winds over this part of the world and also due to its topography where a series of N to S mountainous chains check rain-bearing fronts from the Atlantic. This factor gives rise to the appearance of rain shadows particularly suitable for vine growing. A database was established with standardised 1971-2000 climatic data from 53 selected stations. Fourteen parameters and climatic indices commonly used in viticulture zoning studies were calculated. An analysis of principal components identified the main factors related to climatic variability as well as the climatic indices and parameters with major discriminating scores. These indices included those selected by the Geoviticulture Multicriteria Climatic Classification System (GMCCS). Results show that 13 out of the 36 worldwide viticulture climates specified by the GMCCS appear in Galicia confirming the diversity of viticultural climates present in the region. These results also demonstrate the efficacy of the GCCM system for the differentiation of climatic types on a regional level reinforcing the system’s versatility.

Identification and quantification of c-glucosidic ellagitannins and their derivative in red wine aged in oak barrels

The C-glycosidic ellagitannins constitute a subclass of hydrolyzable tannins of remarkable structural diversity. In this work we first achieved the hemisynthesis of flavano-ellagitannins, then we used them to develop a new efficient detection and quantification procedure for the C-glycosidic ellagitannins as well as flavano-ellagitannins.

‘It’s a small, yappy dog’: The British idea of terroir

Aims: Most consumer research about terroir has focused on wine, particularly with French or other European wine drinkers, rather than those in the Anglo-Saxon world. In Europe, whilst there is no agreement amongst consumers as to what terroir actually is, there is a general recognition of the word and an acceptance that it represents something important

Preliminary steps of a protocol to isolate transcription factors bound to a specific DNA locus in grapevine using CRISPR-dCas9 system

Cis-acting regulatory elements are DNA sequences that can be bound by transcription factors to regulate the expression of genes in a condition-dependent and tissue-specific way. It is nowadays possible to search for DNA motives and sequences that a given transcription factor is binding or at least can, but it is still hard to have a glance at all the transcription factors that are contemporaneously located at the same locus. Inspired by an existing technique that uses the CRISPR-Cas system in mammal cells, we are trying to develop a protocol to study such regulation in Vitis vinifera. Using the highly sequence-specific binding capacity of a catalytically inactive Cas9 protein (dCas9), our idea is to set up a system to target a desired sequence and precipitate all the crosslinked proteins and distantly interacting chromatin at this locus and analyze them.

Energy partitioning and functionality of photosystem II in water-stressed grapevines during heatwaves revealed by continuous measurements of chlorophyll fluorescence

The increased intensity and frequency of heatwaves, coupled with prolonged periods of drought, are a significant threat to viticulture worldwide. During these conditions the more exposed leaves can show visible symptoms of heat damage. We monitored the functionality of photosystem II (PSII) in the field to better understand the impact of heatwaves on canopy performance. A factorial experiment was established in summer 2023 using Shiraz grapevines in the Barossa valley of South Australia, involving water-stressed and well-watered vines.

Spatial variability of the nutrient distribution in Jerez vineyard soils (Spain)

From a fertility standpoint, the vine has to extract from the soil mineral substances necessary for its existence. However, the amount of certain available nutrients does not always correspond to a proportional increase in quality.
