Agronomic behaviour of a native grapevine cultivar from the North of Spain (Vitis vinifera L.) in a mountain viticulture area and in a coastal zone

Abstract

A work involving the finding, the description and the recovery of old grapevine varieties from the north and north east of Spain was begun in the CSIC in the year 1987. Among the red varieties that were found, the Verdejo Negro stood out because of its high quality. Different previous works (Martínez and Pérez 1999, 2000; Martínez et al. 2004, Santiago et al, 2003) have allowed us to know this cultivar from the ampelographic, agronomic and molecular point of view.
The aim of this study was to compare the agronomic behaviour of Verdejo Negro in two different climate areas from North Spain: one from a mountain viticulture area and other from a coastal one. In each of these areas we have an experimental plot. The first one is placed in western south of Asturias region; it is located in the slope of a mountain and has an altitude of about 506 meters with a strong slope; the geological base of the soil is formed basically by shale, sandstone and quartzite. The stocks were planted in 1991. The second plot is located in the south of Galicia region, near from the Atlantic coast, in an area without slope and with an altitude of about 35 meters. The geological bases of the soil are glandular orthogneis. The stocks were planted in 1993. In both cases the plants are grown en espalier, but pruning methodology is different and adapted to the conditions of the two areas studied. In the mountain plot pruning is made using a Guyot system and in the littoral one the Sylvoz system is used.
During four years (2002, 2005, 2006 and 2007) several agronomic parameters were measured such as the fertility rate, weight, length and width of bunches, probable alcoholic grade, must yield, pH and total acidity of the must.
The results showed that for some parameters, such as probable alcoholic grade and pH, there were no significant differences between plots, but for other parameters, as for example fertility rate, grape production per plant, must yield and total acidity, significant differences were found.

Evaluation of intravarietal variability and selection for tolerance to downy mildew: The case of Antão Vaz variety in Portugal 

Antão Vaz is a Portuguese white grapevine variety grown mainly in the wine-growing regions of Southern Portugal, particularly in the Alentejo, Lisbon and Setúbal peninsula regions. It is a very vigorous and productive variety, giving the wines a strong identity. It needs heat and sunlight and prefers deep and dry soils, which makes it tolerant to scald caused by the high summer temperatures of Southern Portugal. However, this variety is very susceptible to downy mildew, caused by plasmopara viticola, a very destructive disease in years with rainy springs.

Différenciation de parcelles de Chenin du Val de Loire, a l’aide de l’etude des flores fongiques des raisins, en utilisant l’outil DGGE

Depuis le millésime 2002, une étude est menée sur la diversité de la flore fongique de parcelles du cépage chenin, situées essentiellement sur les appellations de Vouvray et Montlouis ; deux appellations séparées par le fleuve nommé la Loire. Les parcelles se situent dans des conditions pédoclimatiques différentes, qui se retrouvent au travers des suivis de maturité et l’état sanitaire.

Influenze pedo-ambientali su produzione, qualità e caratteristiche sensoriali dell’Albana di Romagna

L’Albana è il vitigno a bacca bianca tradizionale delle colline della Romagna, dove é presente per più di 2.500 ha. Con le sue uve si produce il vino “Albana di Romagna”, una delle più storiche D.O.C.G. italiane essendo stata costituita nel 1987. La maggiore concentrazione di vigneti di Albana si trova nell’Imolese e nelle colline del Ravennate, ma ben conosciuta per la qualità del prodotto é anche la produzione di Bertinoro, nel Forlivese.

Valorisation of integrated research on vineyard soils. Adaptation to the Val de Loire vineyard

La mise en valeur d’un terroir au travers du vin signifie dans un premier temps le respect du cahier des charges de l’A.O.C correspondante. Dans un second temps, elle sous-entend d’être à l’écoute des évolutions scientifiques, techniques et sociétales afin de satisfaire une production plus respectueuse de l’environnement et de la santé des hommes. Les recherches effectuées par l’Unité Vigne et Vin du centre INRA d’Angers ont débouché sur le concept d’UTB, Unité Terroir de Base (R.Morlat). UTB définit une aire de terrain ou le fonctionnement de la vigne est homogène en tous points.
