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.

Shading nets for the adaptation to climate change: effect on vine physiology and grape quality 

Viticulture is threatened by the environmental modification caused by climate change. Higher temperatures determine an acceleration of the ripening process, which can be detrimental to wine quality. In the mediterranean area, heat waves are also increasingly frequent, with consequent blocking of the vegetative activity of the vines and increased susceptibility to sunburn damage. thus, adaptation strategies are necessary to reduce stress and improve the quality of grape production. Amongst the various techniques available, shading nets represent an interesting alternative for their effects on canopy microclimate (i.e., reduction of photosynthetic activity, improvement of water use efficiency, and slowing down in the ripening process).

AROMA AND SENSORY CHARACTERIZATION OF XINOMAVRO RED WINES FROM DIFFERENT GREEK PROTECTED DESIGNATIONS OF ORIGIN, EFFECT OF TERROIR CHARACTERISTICS

The quality of wines has often been associated with their geographical area of production. The aim of this work was to characterize Protected Designation of Origin (PDO) Xinomavro red wines from different geographical areas of Amyndeon and Naoussa in Northern Greece, elaborated with variables that contribute to their differentiation, such as soil characteristics, altitude, monthly average temperature and rainfall.
Xinomavro fruit parcels from different vineyards within the two PDO zones (5 PDO Naoussa and 6 PDO Amyndeon) were vinified following a standard winemaking process. A total of 25 aroma compounds were quantified using gas chromatography-mass spectrometry (GC-MS) with simultaneous full scan and selected ion monitoring for data recording, and odor activity values (OAVs) were determined.
