Efecto nematicida de extractos de ajo, orujo de uva y alperujo de aceituna; sobre Meloidogyne incognita, en vid, cv Chardonnay = Nematicidal effects of extracts of garlic, grape pomace and olive mill waste, on Meloidogyne incognita, on grapevine cv Chardonnay
(2016)Meloidogyne incognita afecta significativamente al cultivo de vid en Argentina. Actualmente se dispone de pocas herramientas para su control. El objetivo de este trabajo fue comparar el efecto de extractos acuosos de ... -
Effect of elevated temperature on the onset and rate of mesocarp cell death in berries of Shiraz and Chardonnay and its relationship with berry shrivel
(Wiley, 2013-02)Background and Aim: Berry water loss at late stages of ripening is a cultivar dependent‐trait correlated with mesocarp cell death. We tested the hypothesis that elevated temperature anticipates the onset and increases the ... -
Effect of extended maceration and ethanol concentration on the extraction and evolution of phenolics, colour components and sensory attributes of Merlot wines
(Wiley, 2013-02)Background and Aims: Anecdotal evidence suggests that there may be a synergistic effect of ethanol (EtOH ) and prolonged skin contact on the extraction of certain phenolics that may negatively impact wine sensory properties. ... -
Effect of leaf‐to‐fruit ratios on phenolic and sensory profiles of Malbec wines from single high‐wire‐trellised vineyards
(Wiley, 2020-08)BACKGROUND: The single high‐wire system is a free canopy trellis system suitable for warm to hot climates. In a global warming scenario, it arouses as a technological solution since it prevents berry overheating and sunburn. ... -
Elevated temperature and water stress accelerate mesocarp cell death and shrivelling, and decouple sensory traits in Shiraz berries
(2013-11)Both water deficit and elevated temperature are likely to accelerate shrivelling in Shiraz berries with consequences for fruit yield and quality. The process of shrivelling is partially related to mesocarp cell death and ... -
Estrategias de manejo para la transición hacia viñedos sostenibles en Mendoza = Management strategies for the transition to sustainable vineyards in Mendoza
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019-12)En agro-ecosistemas de regadío frágiles como los de Mendoza, con suelos de baja ferti¬lidad, escasas precipitaciones y elevada evapotranspiración estival, el cambio climático tendrá un impacto significativo. Las prácticas ... -
Evaluación de un panel para recuperación de deriva en aplicaciones fitosanitarias en viñedos = Evaluation of a drift recovery panel for phytosanitary treatments in vineyards
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2016-12)Se construyó un panel con deshumidificadores acoplable a máquinas atomizadoras convencionales, capaz de retener el líquido de pulverización que se pierde por deriva. Los objetivos del trabajo fueron: a) verificar su capacidad ... -
Evaluación económica de las pérdidas por granizo en los oasis de la provincia de Mendoza e identificación de eventos extremos
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2022-06)Una de las principales amenazas a la sustentabilidad de los sistemas agrícolas de Mendoza son las tormentas de granizo, las cuales crean un factor de disturbio de las previsiones productivas; si bien constituye un evento ... -
Evaluation of the effectiveness of potential biocontrol yeasts against black sur rot and ochratoxin A occurring under greenhouse and field grape production conditions
(2016)The efficacy of two strains of Lanchancea thermotolerans in preventing the growth and ochratoxin A (OTA) accumulation of ochratoxigenic fungi under greenhouse and field conditions were evaluated during three consecutive ... -
Exhausted grape marc and organic residues composting with polyethylene cover: process and quality evaluation as plant substrate
(Elsevier, 2019-09)In Argentina, wine production is one of the most important economic activities, producing a large quantities of organic wastes. Composting is a viable alternative to treat these residues, with the possibility to obtain ... -
Expression of grapevine AINTEGUMENTA-like genes is associated with variation in ovary and berry size
(2016-05)Fruit size is a highly important trait for most fruit and vegetable crops. This trait has been a main selection target and could be involved in divergent selection processes leading to the differentiation between modern ... -
First report of Dactylonectria alcacerensis, Dactylonectria macrodidyma and Ilyonectria liriodendri associated with black-foot disease of grapevine in Argentina
(American Phytopathological Society, 2022-03-07)Black-foot is a fungal disease that affects young vines and planting material in the countries where grapevines are cultivated. During the 2018 grape-growing season, symptoms of reduced vigor, short internodes, leaf ... -
First report of grapevine red blotch virus infecting grapevine in Argentina
(Springer, 2019-04)Argentina is the fifth wine producer worldwide and 10th global grapevine producer, with over 2,100,000 tons of grapes harvested in 2017. So far, 12 viruses have been identified in grapevine in Argentina (Debat et al. 2019). -
Free Volatile Compounds of cv. Pedro Giménez (Vitis vinifera L.) White Grape Must Grown in San Juan, Argentina
(2018)The free aromatic composition of must from Pedro Giménez grapes, grown in San Juan, Argentina, was characterised. Samples from the vintages of 2008 and 2009 were analysed by gas chromatography–mass spectrometry–solid phase ... -
Genetic characterization of grapevine-infecting Botrytis cinerea isolates from Argentina = Caracterización genética de aislamientos de Botrytis cinerea obtenidos en vides de Argentina
(2010-06)Background: Botrytis cinerea is an ascomycete with a high genetic diversity and complex population structure, as reported from several hosts and sites. However, nothing is known about its genetic diversity in Argentina. Aims: ... -
Germplasm evaluation of the native cultivar “Torrontes Riojano” (Vitis vinífera L.) collected in the Northwest of Argentina
(2015)The cultivar ‘Torrontés Riojano’ (Vitis vinifera L.) was derived from a cross of ‘Muscat of Alexandria’ and ‘Criolla Chica’. Its origin was probably not a directed cross in Mendoza Argentina during the colonial period. ... -
Grapevine morphological shade acclimation is mediated by light quality whereas hydraulic shade acclimation is mediated by light intensity
(Elsevier, 2021-06)Plants acclimate to shade by sensing light signals such as low photosynthetic active radiation (PAR), low blue light (BL) levels and low red-to-far red ratios (R:FR) trough plant photoreceptors cross talk. We previously ... -
