Influenza dei fattori dell’ambiente sulla risposta della pianta, e caratteristiche dell’uva della cv tannat prodotta in vigneti di tre zone climatiche dell’Uruguay

Abstract

Grape typicity valorization can significantly enhance viticultural sector competitiveness to the extent that contributes to the development of a wine so distinctive and unique. This work leads to the characterization of the grapes through indicators expressing environmental effects. This research was carried out during 2008 and 2009 in 4 Tannat cultivar vineyards, in 3 different climatic regions of Uruguay; soil water reserve capacity was similar. By means of climate data, and berry composition and physiological plant response indicators analysis, it was established which were the most influential variables giving specificity and potential of wine in each production area. Climatic factors allowing discrimination of those areas were: water balance during berry ripening, rain amount by crop phoenological stages, degree days during ripening. Referring to plant response: exposed leaf surface and ripening phase duration (in Julian days) were the most important factors followed by predawn leaf water potential at flowering phase, and berry yield. With regard to berry composition the most important factors were sugars and malic acid contents followed by anthocyanic potential and tartaric acid content. These factors could statistically separate the grape growing areas independently of the year effect. We conclude that plant response and berry composition were strongly influenced by the environment. From this the main factors were water supply and temperature during ripening phase.

Vineyard soils and landscapes of the Burgundy Côte (France): a historical construction worth preserving

The construction of vineyard landscapes along the Burgundy Côte is the result of geological processes and of human labour. Substratum diversity in this vineyard is the result of a very long history explained by the diversity of Jurassic sedimentary facies and Tertiary tectonic activity. The nature and thickness of Quaternary deposits (Weichselian scree debris and alluvial fans) reflect sediment dynamics concurrent with the last glaciation.

Influence of the “terroir” (soil, climate and wine grower) on the quality of red Grenache wines in the Rhône Valley

«L’Observatoire Grenache» est un réseau de parcelles qui a été mis en place par l’Institut Rhodanien en Vallée du Rhône sur les millésimes de 1995 à 1999. Composé de 24 parcelles de Vitis vinifera L. cv Grenache noir, ce réseau vise à étudier l’influence du terroir (sol, climat et vigneron) sur la qualité des vins. Les parcelles ont été choisies afin de représenter différentes situations géographiques et géopédologiques de la vallée du Rhône. Le matériel végétal (clone, porte-greffe), la taille (cordon de Royat), la densité et l’âge de la parcelle ont été encadrées. Ainsi les conditions de milieu (sol, climat) et les pratiques du vigneron étaient les principales sources de variations.
