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).
Bioclimatic zoning of Argentinean Malbec grape production
Winegrape production is largely controlled by climate conditions. Identifying how climate conditions impact on vine allows for identifying the suitability of a specific variety for a given region. Given the relevance of the Malbec wine production in Argentina, this study is devoted to derive a Unique Combined Index (UCI) for assessing the suitability of Malbec grape production (MGP) in Argentina.
Temperature variability at local scale in a mountain vineyard
Over the past ten years, climate studies at local scale have been developed in winegrowing areas to improve terroir characterization. In this project, such a study was undertaken in the mountain vineyard of Irouleguy in cooperation with the local cooperative cellar. A network of 31 temperature sensors has been set up inside the region at the beginning of the 2016 vintage.
Exploring grapevine genetic diversity to feed breeding programs to sustain wine viticulture facing warming issues
Genotype x Environment x Practices interactions exert a tight tuning on wine profile. To maintain the typicality of wine produced in traditional regions becomes a critical challenge in the context of rapid climate changes. While some practices may reduce adverse effects of abiotic stresses on the vine (e.g. the use of watering to maintain photosynthesis), the impacts of high temperature stresses on berry development are more difficult to manage.
Selection of Vitis vinifera L. intraspecific hybrids for obtaining wines with high phenolic content
Monastrell is the most extended variety in the South east of Spain. One of our strategies for improving its wines consists in selecting intraspecific hybrids arising from crosses between Monastrell and other high quality varieties, such as Cabernet Sauvignon, looking for those well adapted to our conditions, with a high polyphenol content and a high phenolic extractability, in order to produce highly colored wines.
Characterization of different South American varieties: yield, berry maturity and wine composition
Autochthonous varieties, called ‘criollas’, are highly cultivated in South America. For instance, in Peru or Chile they are used for making Pisco. In Argentina, they represent 33% of the grapevine cultivated area.
Simple trait measurements across rootstock genotypes indicates performance as field grown, grafted vines
CSIRO rootstock breeding aims to provide industry with enhanced material to meet challenges associated with the Australian environment, future climate scenarios (high temperatures, limited water supply and drought) and soil-borne pests (phylloxera and root knot nematodes). In this study, analysis of results from three long term field trials with Shiraz grafted on genotypes from a single family involving Vitis cineria, V. champini, V. riparia and V. rupestris has shown that vine performance and fruit composition can be linked to simple traits, measured on field grown ungrafted seedlings or as ungrafted or grafted nursery grown plants.
Differential expression of susceptible and tolerant grape cultivars on black rot infection
The ascomycota fungus Guignardia bidwellii, responsible for the black rot disease of grapevine is causing increasing damages in Hungary especially in organic vineyards without chemical disease management.
Vines with low inputs for quality wines: what results and what perspectives for the French vineyard?
Tolerance to fungi has been the subject of recent programs in France since the 1970s(A. Bouquet, INRA Montpellier). The objective of these programs, initiated from Muscadinia rotundifolia and based on 5 to 6 backcrosses with different Vitis vinifera varieties, was to approach the profile of V. vinifera to be combined with a strong resistance to powdery and downy mildews from Muscadinia
Classification of wine grape cultivars according to their susceptibility to Botrytis cinerea: importance of fruit maturity
Botrytis cinerea causes one of the most serious diseases in grapevines namely Botrytis Bunch Rot (BBR). A classification of different grapevine cultivars (cvs.) according to their susceptibility to B. cinerea is an essential management indicator in Integrated Pest Management. Although such classifications are available, they are based mostly on professional experience rather than experimental results.
