La promoción de la vitivinicultura argentina: seis décadas, una función, múltiples actores
(Facultad de Humanidades y Ciencias de la Educación, Universidad Nacional de La Plata, 2021-08)El Estado argentino ha participado de múltiples maneras en la promoción de la vitivinicultura argentina, entendida tanto como políticas de apoyo a la innovación, la competitividad y la inversión, como intervención en los ... -
Prospection and identification of traditional-heritage Peruvian grapevine cultivars (Vitis vinifera L.) from Ica and Cañete valleys
(Julius Kühn-Institut Institute for Grapevine Breeding Geilweilerhof, 2022-06-03)Interest in ancient and autochthonous cultivars has increased in recent years since they are directly related to the historical and cultural values of a region. Ica and Cañete valleys (Peru) have a long history of grapevine ... -
Pruning after budburst delays phenology and affects yield components, crop coefficient and total evapotranspiration in Vitis vinífera L. cv. ‘Malbec’ in Mendoza, Argentina
(Elsevier, 2022-02-23)Late pruning is a field technique that has recently been proposed to mitigate the advance in phenology produced by global warming. However, contrasting effects have been observed depending on the cultivar and the date of ... -
Pulgón de la vid Aphis illinoisensis
(EEA La Consulta, INTA, 2022-09)Los adultos miden entre 1,3 y 2 mm. La hembra áptera es de color castaño rojizo oscuro, con patas negras y antenas amarillentas. Las hembras aladas son más oscuras y un poco más grandes. Ambas formas tienen sifones largos ... -
Reflexiones en torno a la innovación tecnológica en la vitivinicultura de San Juan
(IADE, 2019-08-16)El presente artículo tiene por objetivo analizar y reflexionar sobre las trayectorias de algunas políticas de innovación para el sector vitivinícola del Instituto Nacional de Tecnología Agropecuaria (INTA) en la provincia ... -
Regulación de la hidratación y la turgencia foliares por mecanismos evitadores del estrés, y resistencia a déficit hídrico en vid
(Universidad Nacional de Cuyo, 2011)El transporte del agua en las plantas es impulsado por diferencias de energía libre entre el suelo y la atmósfera, y está regulado por mecanismos biológicos evitadores, como el cierre estomático. La hidratación y la turgencia ... -
Relaciones entre cavitación y cierre estomático en vides sometidas a déficit hídrico
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo., 2011)La cavitación es una disfunción fisiológica que ocurre en el xilema de las plantas cuando estas están bajo déficit hídrico, y que entraña una pérdida de su conductancia hidráulica (kL), cuando algunos vasos se llenan de ... -
Relationships among Gene Expression and Anthocyanin Composition of Malbec Grapevine Clones
(2014-07)Anthocyanin profiles are commonly used for grapevine cultivar identification because it is currently accepted that this trait is closely related to their genetic characteristics. Nevertheless, the extent of the variation ... -
Review: critical appraisal of methods to investigate the effect of temperature on grapevine berry composition
(Wiley, 2015-02)The grapevine is an economically important crop and a model species of long‐lived perennials widely used in bioclimatic studies. Ambient temperature modulates berry composition, hence the significant research effort in ... -
Role of ABA and Gibberellin A3 on gene expression pattern of sugar transporters and invertases in Vitis vinifera cv. Malbec during berry ripening
(2018-03)Sugars are key constituents that affect quality of grape berries, and consequently the grape metabolic profile relevant to wine’s industry. However, enzymes and transporter genes expression involved in sugar transport at ... -
Rootstocks increase grapevine tolerance to NaCl through ion compartmentalization and exclusion
(Springer, 2020-09)The productivity of Vitis vinifera L. is limited by salinity, especially under water and drainage deficits, and could aggravate with climate change. The use of tolerant rootstocks is a strategy against salinity that helps ... -
Secado de uva en planta
(Ediciones INTA, 2022)En San Juan se introdujo en el año 2007 la tecnología de secado de uva en planta o Dry on the Vine (DOV) en el primer Simposio Internacional de Uva de Mesa y Pasas organizado por INTA . El esfuerzo conjunto entre el sector ... -
Selection of non-Saccharomyces yeasts to be used in grape musts with high alcoholic potential: A strategy to obtain wine with reduced etanol content
(2017)Ethanol content of wine has increased over the last decades as consequence of searching phenolic maturity, requiring increased grape maturity. This may result in the production of wines with excessive alcohol levels ... -
Semi physical growth model of Lobesia botrana under laboratory conditions for Argentina’s Cuyo region
(Elsevier, 2021-12-21)Lobesia botrana is a quarantine pest from Argentina and other countries in the world. It causes damage to the vine in its different growth stages leading to losses in wine production. To develop pest control strategies ... -

Soil water availability during spring modulates canopy growth and impacts the chemical and sensory composition of Shiraz fruit and wine
(Wiley, 2021-06)Background and Aim: Reduced rainfall during vine dormancy and supplementary irrigation during winter or at spring impact on vine growth partitioning. We assess the implications that induced changes on canopy growth due to ... -
Spray with plant growth regulators at full bloom may improve quality for storage of ’Superior Seedless’ table grapes by modifying the vascular system of the bunch
(Elsevier, 2021-06)The quality traits of table grape most appreciated by the consumers are berry size, bunch architecture, and freshness appearance (especially after post-harvest cold storage). Loss of bunch freshness reduces the value and ... -
