The 20th GiESCO International Meeting is held in Mendoza (Argentina), November 5-10, 2017.
American and crossbreed grapes varieties show a good adaptation to the climatic conditions of different Brazilian regions, representing about 70% of total production of Santa Catarina state (Brazil).
In Brazil, the fifth largest wine producer in the Southern Hemisphere, one of the more important regions is known as “Campanha”, in Rio Grande do Sul State.
An accurate yield estimation is a constant demand in the winemaking industry.
The number of inflorescence primordia (IP) in compound buds has been previously reported to be closely related to the yield in the coming season.
Vineyard yield forecasting is a key issue for vintage scheduling and for optimizing vineyard and winery resources.
Carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) are the greenhouse gases (GHG) that have suffered a more marked concentration increase since the Industrial Revolution, with agriculture accounting for 13.5% of the worldwide emissions.
The estimation of Leaf area index (LAI) at large spatial scales (vineyard level) is a crucial factor for several Precision Viticulture (PV) applications, associated with the plant growth modeling and decision support for irrigation and canopy management.
This work is carried out during 2016 on a commercial vineyard to evaluate productivity and wine final characteristics in different subplots discriminated against by remote sensing.
Representative evapotranspiration (ET) measurements over vineyards are today still challenging due to spatial variability of plants, soil conditions and surface topography.
Soil water availability is one of the main determinants of crop yield and of adaptation to a changing climate. The aim of this study was to analyse the soil water regime, as determined by climatic conditions, in combination with the intra-specific biodiversity of yield responses of grapevine to water availability. The adaptability of wine-producing cultivars to future climate was thus assessed.
