Water as a critical issue for viticulture in southern Europe: sustainability vs...
Costa, Joaquim Miguel; Vaz, Margarida; Escalona, J.M.; Egipto, Ricardo; Lopes, Carlos Manuel; Medrano, H; Chaves, Maria ManuelaWater is a vulnerable resource in the Mediterranean region, but irrigation demands have been increasing to mitigate effects of environmental stress. Sustainable wine production involves the precise use of water in the vineyard and winery. Improved knowledge on grapevine ecophysiology and genetics, the use of sensors for soil and canopy monitoring, plant phenotyping and improved crop management can help save wat...
Using the fraction of transpirable soil water to estimate grapevine leaf water ...
Egipto, Ricardo; Costa, J. Miguel; Silvestre, José; Lopes, Carlos M.Context and purpose of the study – Weather uncertainty is forcing Mediterranean winegrowers to adopt new irrigation strategies to cope with water scarcity while ensuring a sustainable yield and improved berry and wine quality standards. Therefore, more accurate and high-resolution monitoring of soil water content and vine water status is a major concern. Leaf water potential measured at pre-dawn (YPD) is consid...
Modulation of the berry skin transcriptome of cv. tempranillo induced by water ...
Carvalho, Luisa C; Ramos, Miguel J. N.; Faísca-Silva, David; Marreiros, Pedro; Fernandes, João C.; Egipto, Ricardo; Lopes, Carlos M.; Amâncio, SaraClimate change in the Mediterranean area is making summers warmer and dryer. Grapevine (Vitis vinifera L.) is mostly important for wine production in Mediterranean countries, and the variety Tempranillo is one of the most cultivated in Spain and Portugal. Drought decreases yield and quality and causes important economic losses. As full irrigation has negative effects on quality and water is scarce in this regio...
The role of soil temperature in mediterranean vineyards in a climate change con...
Costa, J. Miguel; Egipto, Ricardo; Aguiar, Francisca C.; Marques, Paulo; Nogales, Amaia; Madeira, ManuelThe wine sector faces important challenges related to sustainability issues and the impact of climate change. More frequent extreme climate conditions (high temperatures coupled with severe drought periods) have become a matter of concern for the wine sector of typically dry and warm regions, such as the Mediterranean European countries. Soil is a natural resource crucial to sustaining the equilibrium of ecosys...
Sensory and chemical characteristic of white monovarietal wines produced from v...
Roque, Rita; Caldeira, Ilda; Anjos, O.; Lourenço, Sílvia; Amaral, João; Damásio, Miguel; Egipto, Ricardo; Silvestre, JoséThe search and study of varieties that are better adapted to climatic variations is one of the strategies to help the wine sector to overcome the challenges that will arise in the future.
Volatile profile of 15 monovarietal white wines produced from grapes cultivated...
Roque, Rita; Caldeira, Ilda; Anjos, O.; Lourenço, Sílvia; Amaral, João; Damásio, Miguel; Egipto, Ricardo; Silvestre, JoséClimate change trends and impacts could influence drastically the economy and the way that we produce or adapt cultures in near future. The higher air temperatures can modify the characteristics of wine, that depends on many factors, including the conditions they're grown in. Nevertheless, some varieties can be more adapted for these climate changes and produce high quality wines.
Stratégies pour une production viticole plus durable et compétitive au Portugal...
Costa, J. Miguel; Rodrigues, Gonçalo C.; Egipto, Ricardo; Silvestre, José; Lopes, Carlos M.Une production de raisin et de vin plus durable dépend d’une utilisation et d’une gestion plus efficaces du sol et de l’eau. Ceci est particulièrement pertinent pour les pays d’Europe du Sud, comme le Portugal, caractérisés par des sols appauvris, des ressources en eau limitées et une augmentation de la surface irriguée en pour atténuer les impacts climatiques sur le rendement et la composition des baies et min...
Developmental Regulation of Transcription in Touriga Nacional Berries under Def...
Carvalho, Luísa C.; Ramos, Miguel N.J.; Faísca-Silva, David; van der Kellen, D.; Fernandes, João C.; Egipto, Ricardo; Lopes, C.M.; Amâncio, SaraGrapevine (Vitis vinifera L.) is one of the most economically important crops worldwide, especially due to the economic relevance of wine production. Abiotic stress, such as drought, may contribute to low yield, shifts in quality, and important economic loss. The predicted climate change phenomena point to warmer and dryer Mediterranean environmental conditions; as such, it is paramount to study the effects of ...
Pegada hídrica – um contributo para a sustentabilidade da fileira vitivinícola
Saraiva, Artur; Egipto, Ricardo; Presumido, Pedro Henrique; Jorge, Célia; Parenzan, Sílvia; Amaral, Anabela; Ribeiro, A.C.; Ferreira, AlbertinaA escassez de água e o aumento da temperatura decorrente das alterações climáticas têm vindo a levantar preocupações junto do sector vitivinícola, devido ao seu impacto na produção e qualidade do vinho. O uso eficiente dos recursos naturais e a subsequente redução dos custos de produção é hoje um dos objetivos dos vitivinicultores. O projeto WineWaterFootprint avaliou a pegada hídrica na fileira vitivinícola, a...
Mixed fermentation with Metschnikowia pulcherrima using different grape varieties
Duarte, Filomena L.; Egipto, Ricardo; Baleiras-Couto, M. MargaridaThe study and use of non-Saccharomyces yeasts to wine improvement and diversification has gained considerable relevance in recent years. The present work reports a pilot-scale winery assay of mixed fermentation with a commercial strain of Metschnikowia pulcherrima, tested in five white and nine red grape varieties. Two modalities were assayed, one with the addition of M. pulcherrima at time zero and addition of...
