Varieties and rootstocks: an important mean for adaptation to terroir

Abstract

A large genetic diversity exists among V. vinifera varieties, but also among cultivated rootstocks. This diversity is important to adapt plant material to different environmental conditions and contributes to the expression of terroir. Plasticity, i.e. the level of modification of the expression of individual characteristics of a genotype in different environments, is also important for adaptation. The most important physiological parameters which contribute to this adaptation are briefly reviewed. For varieties, phenology, drought responses and ripening processes are crucial. For rootstocks, variability in nutrients and water uptake, as well as their effects on whole plant development is important. A better description and understanding of the genetic variability and plasticity for these traits is highly required in order to improve the adaptation of the plant material to the current growth conditions. It will also help to develop strategies in order to respond to the ongoing climate change.

Identification of the agronomical and landscapes potentialities in “Côtes du Rhône” area (France)

“Côtes du Rhône”, like many other controlled appellation wine, represents high stakes in the economical, social cultural and historical domains. The scenery formed by vineyards reveals these cultural values. It offers by a pleasant and appealing environment for the inhabitants and the tourists. It is also a powerful marketing tool for the winemakers.

Unveiling the chemical headspace of sparkling wine glasses by laser spectroscopy

Right after serving a sparkling wine into a glass, thousands of rising and bursting bubbles convey gas-phase CO2 and volatile organic compounds (VOCs) in the headspace above the champagne surface, thus progressively modifying the gaseous chemical space perceived by the consumer [1].

To what extent does vine balance actually drive fruit composition?

Context and purpose of the study ‐ Vine balance is a concept describing the relationship between carbon assimilation (usually estimated using a measure of vine vigour, e.g. pruning weight) and its utilisation for fruit production (usually estimated using harvest yield). Manipulating vine balance through leaf area or crop load adjustments affects the proportion of the vine’s total carbohydrate production required to mature the fruit. It is commonly considered that composition of the berry, and resulting wine, is strongly affected by vine balance.
