Clonal selection has become the almost unique way of propagating plant material for vineyards. Clonal selection allows control of virus diseases and selection of genotypes on agronomic, viticultural or enological criteria.
Ces activités et recherches font observer principalement que innovantes gestion des sarments herbaces et la défoliation combinée avec la “Doppia Maturazione Ragionata-Double Maturation Raisonnée” (DMR)
Algeria has many indigenous varieties of vine that their valorization still remains to be undertaken. Homonyms and synonyms have been highlighted in studies of molecular characterization.
Different sensor types are available to assess grape bunch/berry temperature, but to study its variability within complex grapevine canopies is difficult.
A total of 704 Cabernet Sauvignon (CS8) vines were grafted on 10 different rootstocks and compared to an own-rooted control as part of a new vineyard planting on the terraces above the Estrella River in the Paso Robles AVA.
Phylloxera (Daktulosphaira vitifoliae) has always been considered one of the most dreaded diseases of Algerians vineyards .
The genetic variability among and within ancient grapevine varieties is a basis for the innovation in wine sector in the future. Therefore, genetic variability should be preserved and simultaneously evaluated through the most efficient methods.
The agronomical and oenological performance of six clones of Gamay noir (V. vinifera L.) were evaluated for two years in a high altitude en¬vironment (about 750 m asl) in Aosta Valley (North-Western Italy).
The objective of this work is the development of the culture of indigenous varieties of Vitis vinifera.L minors whose culture remains limited to a few feet from private owners in Algeria.
The purpose of this study was to characterize the tropical Brazilian wines, first vintage of 2008, by instrumental and sensorial analysis.
Many vineyards along the world produce high yield and high alcohol level wines because of different factors, so bunch thinning technique has become more usual in order to balance the production.
Ces recherches ont été menées depuis plus de 25 années et celles réalisées récemment (20082012), dans des localités ciblés, des modèles de production, des variétés, des situations et des objectifs très différents
The lack of more sustainable options for the bud break of grapevines in mild winter regions is a limiting factor due to restrictions on the use of agrochemicals.
The grapevine needs some period of chilling to overcome the dormancy, thus the cultivation of this plant in subtropical and tropical regions is only possible with the use of synthetic products for bud break.
Grapevine rupestris stem pitting-associated virus (GRSPaV) is a widely spread virus affecting Vitis spp. Although it established a compatible viral interaction in Vitis vinifera L. without the development of phenotypic alterations, it can occur as distinct variants that showed different symptoms on diverse Vitis species.
