Heat requirements for grapevine varieties is essential information to adapt plant material in a changing climate

Abstract

Precocity for fruit ripening is a genetically determined characteristic that is highly variable from one cultivar to another. In traditional wine-growing regions of Europe, growers have used this property to adapt the vines to local climatic conditions in order to maximize terroir expression. Due to global warming, the choice of later ripening grapevine varieties might be necessary in many regions to maintain late ripening conditions favourable for terroir expression. Hence, precise heat requirement data for each grapevine variety is essential information. Phenology (budburst, flowering, veraison and ripeness) and temperature data have been collected for many varieties in a wide range of locations over a great number of vintages. Heat summations base of 10°C were calculated for each variety to reach key phenological stages. However, a more sophisticated agro-climatic model might be necessary to increase the precision of a classification of varieties according to their precocity.

La hiérarchisation des Coteaux du Languedoc: une application concrète du zonage vitivinicole

L’A.O.C. Coteaux du Languedoc est située dans le Sud de la France, dans la partie Ouest de la bordure méditerranéenne. Elle forme un vaste amphithéâtre largement ouvert sur la mer méditerranée. L’Appellation a été constituée en 1960 par le regroupement de 14 anciennes petites appellations d’origine représentant 55 communes éparpillées dans les départements de l’Aude, de l’Hérault et du Gard. Par la suite, plusieurs extensions successives ont conduit à un ensemble actuellement composé de 168 communes.

A pragmatic modeling approach to assessing vine water status

Climate change scenarios suggest an increase in temperatures and an intensification of summer drought. Measuring seasonal plant water status is an essential step in choosing appropriate adaptations to ensure yields and quality of agricultural produce. The water status of grapevines is known to be a key factor for yield, maturity of grapes and wine quality. Several techniques exist to measure the water status of soil and plants, but stem water potential proved to be a simple and precise tool for different plant species.

Time stability of visitors’ preferences for preserving the worldwide cultural landscape alto douro wine region

The Alto Douro Wine Region (ADWR) was classified a world heritage site, specifically as a cultural landscape, by UNESCO, in 2001. The well known “Porto Wine” and other high quality wines are produced in the Douro region. As an attraction and touristic site, the cultural site has to meet the needs of more demanding visitors and to compete with a growing number of cultural sites, also classified by UNESCO. To achieve this goal, landscape managers and public authorities have much to profit from knowing and understanding visitors’ preferences regarding the attributes associated to its outstanding universal value.
