Different sensor types are available to assess grape bunch/berry temperature, but to study its variability within complex grapevine canopies is difficult.

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.

Over the last few decades, the study of the grapevine water status has been the focus of much attention. Numerous indicators, direct and indirect, of plant water status have been put forward and tested.

Berry size has always been considered a quality factor for wine production, but size variation is a reality in commercial vineyards. In this study, Syrah (clone SH 9C) grapes from a single vineyard, located in the semi-arid Breede River Valley of South Africa

The impact of berry size on the composition and the oenological potential of grapes is currently a topic under discussion.

Microvine is a natural mutant of grapevine characterized by a dwarf, rapid cycling and continuous flowering phenotype.

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).

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.

In the last decades efforts have been made in grapevine genetic and sanitary improvement through clonal selection procedures.

Grapevine Fanleaf Virus (GFLV) is the main virus disease on grapevine. Yield and vigour decrease quickly due to viral diseases which considerably reduces the lifespan of a vineyard plot.

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.

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.

Temperature is the major climate element for grapevine development, controlling the rhythm at which several phenological stages like bud break, flowering, veraison and maturity occur during the biological cycle.

Climate is one of the main conditioning factors for viticulture. Furthermore, there are significant weather variations among years, which influence grapevine phenology.

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)

Ces recherches ont été menées depuis plus de 25 années et celles réalisées récemment (20082012), dans des localités ciblés, des modèles de production, des variétés, des situations et des objectifs très différents

Evolution of grape phenolic maturation (of 70 genotypes) was monitored using the Polyphenolic Meter Index (PMI) method. The experiment was carried out in 2011 in experimental vineyards in Rauscedo, Italy.
