An accurate yield estimation is a constant demand in the winemaking industry.
Assessing grapevine bud fruitfulness from different cultivars to assist early yield prediction
The number of inflorescence primordia (IP) in compound buds has been previously reported to be closely related to the yield in the coming season.
Research on sampling methodologies for vineyard yield forecasting in different cultivars and trellis systems
Vineyard yield forecasting is a key issue for vintage scheduling and for optimizing vineyard and winery resources.
Optimisation of GC-MS and GC-ECD chromatographic methods to determine the greenhouse gas emissions from vineyard soil
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.
Modeling vineyard leaf area index using remote sensing data at different spatial resolutions
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.
Evaluation of vineyard differential management zones by remote sensing and relationship with productivity and wine quality (cv. Tempranillo) in the A.O. Ribera del Duero
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.
Sensible heat fluxes by scintillometer and Eddy covariance in an irrigated vineyard
Representative evapotranspiration (ET) measurements over vineyards are today still challenging due to spatial variability of plants, soil conditions and surface topography.
Determinants of adaptation of grapevine to an evolving climate: hydrological conditions and cultivars biodiversity
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.
Downscaling future climate scenarios to vineyard scale
The IPCC has created several climate scenarios evaluating the impacts and consequences of climate change. All agricultural sectors will be concerned, in particular grape and wine production. Climate, especially temperature, has a key role in grapevine development.
Vulnerability of climate variability in the southern wine region of Uruguay
Over a wine region, the knowledge of climate variability is primordial to contribute to adaptation issues to climate change (CC). Interviews were carried out using the method developed in TERADCLIM Project to evaluate winegrowers perception of CC and ways of adaptation.
Trends in climate parameters related to winegrape production in North Greece and viticultural consequences
In this study, dates of vine developmental stages and harvest dates of eight winegrape varieties in two major wine producing regions of North Greece (Kavala and Naoussa) were gathered. Data of the basic developmental stages (budburst, flowering and veraison) for three varieties in Naoussa covered a period of 8 years while harvest dates observations ranged from 13 to 35 years for eight varieties in both regions.
Physiological and yield performance of Vitis vinifera L. cvs. (Riesling and Cabernet-Sauvignon) under free air carbon dioxide enrichment (face)
Two main challenges of a changing climate are the increase in atmospheric carbon dioxide (CO2) and temperature in relation to physiological responses and yield performance of plants. To investigate responses of field grown grapevines under elevated CO2 (+20 %) conditions a FACE (Free Air Carbon dioxide Enrichment) facility for Vitis vinifera cvs. Riesling and Cabernet Sauvignon was established at Geisenheim (50°N, 8°E, Germany) in 2012.
Organic and biodynamic viticulture: A systematic review and meta-analysis
In agriculture including viticulture demand for organically grown crops has developed exponentially in the last few decades. Particularly in the wine sector organic and biodynamic management system are gaining more and more importance and some of the most prestigious wineries have converted to organic or biodynamic viticulture.
Economic sustainability of Canadian grape industry. A comparative analysis of Okanagan valley and Niagara peninsula
Sustainability is a broad concept, and its economic component is not often incorporated when sustainable farming practices are studied. This study analyses some economic parameters related to the size of vineyard operation as individual business or associated with a winery.
A comparison of nonchemical weed management practices on vine growth, productivity, undervine vegetation and microbial ecosystems
Herbicides are commonly applied under vines to minimize the competition by weeds. As concerns about using fewer chemical inputs have developed, alternative methods to herbicides for undervine weed control are increasingly being adopted. These trials were carried out in New Zealand on Sauvignon blanc, Pinot noir, and Merlot from 2012/13-2015/16.
Integrating climate and satellite remote sensing to assess the reaction of Vitis vinifera L. to a changing environment in the Western Cape, South Africa
In the context of climate change and the complex terrain of the Western Cape, increased resolution of climate data is crucial for effective adaptive strategies. Reliable climate data can be costly, and currently requires intensive data validation; hence the study aimed to find an alternative resource to quantify the climate over the spatial extent of the Western Cape, for possible semi-real time applications.
Viticultural suitability of São Joaquim, Santa Catarina state, Brazil
São Joaquim (28º17’38 “S and 49º55’55” O) is a viticultural region located on the Santa Catarina Plateau, south region of Brazil, which is known for vineyards that produce fine wines from grapes cultivated at altitude (> 900 m). It is amongst the coldest (annual average of 13.42 ºC, 1832.36 hours of solar radiation and 1680.23 mm of precipitation) and the highest (715 – 1638 m) Brazilian’s viticultural regions, with hilly relief (43% of slopes between 20 – 45% of declivity, with no preferred direction).
