Influence of the vintage, clone and rootstock on the chemical characteristics of Syrah tropical wines from Brazil

In the Northeast of Brazil, vines can produce twice a year, because annual average temperature is 26ºC, with high solar radiation and water availability for irrigation. Many cultivars have been tested according to their adaptation to the climate and soil, and the main variety used for red wines is Syrah. This work aimed to evaluate […]

Effects of rootstock and environment on the behaviour of autochthone grapevine varieties in the Douro region

In an experiment located at Quinta da Cavadinha, Sabrosa, Douro Region the behaviour of the varieties Touriga Nacional (TN), Tinta Barroca (TB), Touriga Franca (TF) and Tinta Roriz (TR), grafted onto the rootstocks Rupestris du Lot, R110, R99, 1103P and 196-17, was accessed over 11 years between 2001 and 2011. The main results point to […]

Terroir effects on the response of Tempranillo grapevines to irrigation in four locations of Spain: agronomic performance and water relations

We report the effects of different drip irrigation treatments on the agronomic performance and water relations of Tempranillo grapevines, pruned to a bilateral cordon, trained to VSP and under similar cultural practices, in four different locations of Spain, during the 2009-2011 seasons. In three locations (Requena, Badajoz and Valladolid) a pre-veraison deficit irrigation strategy (DIP, […]

Conservation of intravarietal diversity in France: exhaustive overview and perspectives

Since the renewal of the French vineyard after the Phylloxera crisis, the panorama of cultivated varieties has dramatically changed. This current genetic erosion is due to the increasing interest in some cultivars that are widely spread out. Meanwhile, clonal selection has contributed to the development of these grape varieties driving towards a massive loss of […]

Varieties and rootstocks: an important mean for adaptation to terroir

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 […]
