Effects of grapevine leafroll associated virus 2 infection on leaf net photosynthesis, yield and berry quality in Vitis vinifera cv. Malbec

Jul 7, 2026 | GiESCO 2017 - Session 4: Vine physiology

Grapevine leafroll associated virus 2 (GLRaV-2) is one of the most common damaging viral diseases in vines, causing significant reductions in photosynthesis, yield and grape quality. In this study, we tested the hypothesis that the leaf net photosynthesis and the transport of sugars to the berries is progressively reduced along the season in vines infected with GLRaV-2, and consequently, the yield (kg per plant) and total soluble solids (TSS) at the berry harvest-ripe stage are lower than non-infected vines.

Syrah wine from São Paulo’s high lands – Brazil, chemical and sensorial characterization, with a extemporaneous production cycle

Jul 7, 2026 | GiESCO 2017 - Session 2: Sustainability + zoning

Brazil has a wide territorial area, with much differentiated edaphoclimatic characteristics. It makes this study important to characterize new regions with viticulture potential.

Influence of genotype and water availability on respiratory costs and plant carbon balance in grapevines (Vitis vinifera L.)

Jul 7, 2026 | GiESCO 2017 - Session 4: Vine physiology

Due to the important contribution of agriculture to the global carbon dioxide (CO2) balance, new techniques are currently being developed to accurately estimate the carbon balance of different crops. Field studies to date in grapevines have been based on carbon allocation and biomass accumulation dynamics.

Phenological behavior and evolution of maturation of grapes of juice preparation

Jul 7, 2026 | GiESCO 2017 - Session 9: Enology

The ripening level of the grape is one of the most important factors in the quality of its derivatives, because of the complex phenomena inherently related to the varieties and environmental conditions. The objective of the present study was to monitor the phenological development of the Chardonnay variety and to evaluate the influence of the different ripening points on the production of juices.

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

Within the current context of climate change, the choice of variety and rootstock for each specific pedo-climatite becomes critical.

Sensory profile: impact of grape vine yield and irrigation strategies in Vitis vinifera Cabernet-Sauvignon

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

The yield and irrigation strategies have an effect in maturity and chemical profile of grape, also an effect on the sensorial profile of the wine.

Impact of the source sink ratio on vegetative growth, yield, and reserves accumulation on a minimal pruning vineyard

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

Vines under minimal pruning reach a balance between vegetative growth and yield.

Influence of trellis system and shoot density of a vineyard in light interception and productivity

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

Different types of trellis systems determine different canopy spatial distributions, allowing greater or lesser shoot density in order to maximize the efficiency of light interception and productivity.

Effect of polyethylene soil coverage, in the maturation of Vitis vinifera grape in the variety Tannat

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

The effect of soil cover with polyethylene on the physiological and grape quality parameters was evaluated during three seasons in a commercial vineyard in southern Uruguay.

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

Important vineyard irrigated areas of Mendoza show salinity problems.

Does the content of polyphenols in grape (cv. Malbec) vary with the chemical properties variation of the soils?

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

In recent years, the wine industry has become increasingly interested in the influence of the terroir characteristics on the features of a wine and in particular, the mechanisms by which a soil influences wine quality.

Effect of water regime on anthocyanin composition of four red winegrape cultivars under Mediterranean conditions

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

Grape anthocyanin content and composition exhibit a distinctive profile among red varieties, determining wine color intensity, hue and stability.

Water status and physiological efficiency in cv. Cabernet-Sauvignon: response to different water regimes including the alternative of PRD on the row

Jul 7, 2026 | GiESCO 2017 - Session 5: Vineyard management

Irrigation management is a critical aspect in grapevine cultivation to regularize grape production and grape quality in areas of clear rainfall limitation, especially with climate change.

Molecular tools for selection and characterisation of lactic acid bacteria associated to Patagonian red wines

Jul 7, 2026 | GiESCO 2017 - Session 6: Precision viticulture, modelling, and techniques

The selection of lactic acid bacteria (LAB) from a wine-producing area is necessary to the formulation of native malolactic starter cultures, well adapted to local winemaking practices, and able of enhancing the regional wine typicality.
