Influencia de cuatro alternativas de crianza en roble sobre el color, la composición polifenológica y las características organolépticas de vinos Malbec y Cabernet Sauvignon
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2009-05)Los costos de las barricas, por el tipo de cambio en la Argentina, son inaccesibles para muchas bodegas. Debido a esto, muchas de ellas utilizan sistemas alternativos de crianza, no conociendo claramente las consecuencias ... -
Influencia de seis portainjertos de vid sobre el comportamiento vitícola de la cv. Malbec y estudio de las relaciones hídricas que se establecen
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2008)El uso de portainjertos en la vid se ha difundido por su resistencia a filoxera y nemátodos, pero también por su tolerancia a condiciones adversas del suelo. Por otro lado, los portainjertos modifican las relaciones ... -
Interactive effects of high temperature and water deficit on Malbec grapevines
(Wiley, 2019-06-26)Background and Aims: Studies of the interactive effects of drought and high temperature on the physiological responses of grapevines (Vitis spp.) are scarce. We tested whether well‐watered, potted vines were able to avoid ... -
Late pruning modifies leaf to fruit ratio and shifts maturity period, affecting berry and wine composition in Vitis vinífera L. cv. ‘Malbec’ in Mendoza, Argentina
(Elsevier, 2023-04)Higher temperatures in recent years have advanced berry ripening and harvest date, decoupling berry sugar accumulation of anthocyanins final concentration and therefore reducing wine potential color. Late pruning is proposed ... -
Microwave-assisted extraction applied to Merlot grapes with contrasting maturity levels: effects on phenolic chemistry and wine color
(MDPI, 2019-01)Merlot grapes were harvested with three maturity levels (21.1, 23.1, and 25.1 Brix), and processed with or without the application of microwave-assisted extraction (MW). The detailed phenolic composition and color were ... -
Modeling vegetative vigour in grapevine: unraveling underlying mechanisms
(Elsevier, 2020-12)Mechanistic modeling constitutes a powerful tool to unravel complex biological phenomena. This study describes the construction of a mechanistic, dynamic model for grapevine plant growth and canopy biomass (vigor). To ... -
Molecular and ampelographic characterization of Pisco grapevine accessions conserved in a germplasm collection center of the Ica, Peru = Caracterización molecular y ampelográfica de accesiones de vides pisqueras conservadas en un centro de colección de germoplasma de Ica, Perú
(Facultad de Ciencias Agropecuarias, Universidad de Trujillo (Perú), 2021-12)Pisco is a distillate of cultural and economic importance for Peru, made from heterogeneous vine varieties called "pisqueras", covered by a Pisco Denomination of Origin legislation. The aim was to confirm the varietal ... -
Morphology and hydraulic architecture of Vitis vinífera L. cv. Syrah and Torrontes Riojano plants are unaffected by variations in red to far-red ratio
(2016)Plants have evolved an array of specific photoreceptors to acclimate to the light environment. By sensing light signals, photoreceptors modulate plant morphology, carbon- and water-physiology, crop yield and quality of ... -
Parámetros biológicos y poblacionales de Planococcus ficus (Hemiptera: Pseudococcidae) sobre dos cultivares de Vitis vinifera = Biological and populational parameters of Planococcus ficus (Hemiptera: Pseudococcidae) on two cultivars of Vitis vinifera
(2016)La cochinilla harinosa Planococcus ficus Signoret causa severos daños en viñedos argentinos. El objetivo de este trabajo es comparar los parámetros biológicos y poblacionales de P. ficus sobre los cultivares de Vitis ... -
Phenolic characterisation of red wines from different grape varieties cultivated in Mendoza province (Argentina)
(Wiley, 2012-02)Background: Knowledge of the chemical composition of wine and its association with the grape variety/cultivar is of paramount importance in oenology and a necessary tool for marketing. Phenolic compounds are very important ... -
La poda tardía como estrategia de adaptación al cambio climático en la variedad Malbec (Vitis vinifera) en Mendoza, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2023)Las temperaturas más altas en los últimos años han generado un avance en la madurez de las bayas y han reducido el número de días a cosecha. También ha generado un desacople entre la acumulación de azúcar respecto a las ... -
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 ... -
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 ... -
