A dynamic model for sodium intoxication unravels salt tolerance in grapevine (Vitis vinifera L.) rootstocks
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12)A correct selection of salt-tolerant plants should consider the relative effects of the various existing tolerance mechanisms. When toxic ions, like Na+, reach the leaves, they affect the photosynthetic apparatus, reducing ... -
A functional–structural plant model that simulates whole- canopy gas exchange of grapevine plants (Vitis vinifera L.) under different training systems
(Oxford University Press, 2020-09)Background and Aims: Scaling from single-leaf to whole-canopy photosynthesis faces several complexities related to variations in light interception and leaf properties. To evaluate the impact of canopy strucuture on gas ... -
A leaf gas exchange model that accounts for intra‐canopy variability by considering leaf nitrogen content and local acclimation to radiation in grapevine (Vitis vinifera L.)
(Wiley, 2012-07)Understanding the distribution of gas exchange within a plant is a prerequisite for scaling up from leaves to canopies. We evaluated whether leaf traits were reliable predictors of the effects of leaf ageing and leaf ... -
Actividad forrajera de Acromyrmex striatus (Roger,1863) (Formicidae: Attini) en un viñedo orgánico en Mendoza, Argentina
(Ediciones INTA, 2019-08)Las hormigas cortadoras se convierten en plagas agrícolas, debido a su habilidad de utilizar especies vegetales como sustrato para el desarrollo del hongo simbionte que constituye su alimento. Los objetivos de este trabajo ... -
Actividad forrajera y de mantenimiento de nido de la hormiga cortadora de hojas Acromyrmex lobicornis (Hymenoptera: Formicidae) en un viñedo orgánico inserto en el desierto de Monte en Mendoza, Argentina
(Sociedad Entomologica Argentina, 2021-12)Exclusivas del Neotrópico, las hormigas cortadoras de hojas son consideradas plagas agrícolas, aunque pueden tener también un efecto positivo sobre las plantas. En los viñedos mendocinos la biodiversidad vegetal es mínima, ... -
Application of vine-shoot chips during winemaking and aging of Malbec and Bonarda wines
(MDPI Publication, 2021-07)The growing demand in recent years for sustainable wine production has led to the management of waste and by-products. Among them, vine-shoots could be used as additives comparable to the oak fragments widely employed in ... -
Biocontrol of postharvest Alternaria decay in table grapes from Argentina
(Elsevier, 2019-03-29)Postharvest diseases cause considerable losses of fruit during transportation and storage. Synthetic fungicides are primarily used to control them; however, the recent trend is to shif toward safer and more eco-friendly ... -
Biodiversity of Aspergillus section Nigri populations in Argentinian vineyards and ochratoxin A contamination
(2013-12)Aspergillus section Nigri are described as the main source of ochratoxin A (OTA) contamination in grapes and wine worldwide. The knowledge of the factors affecting grape contamination by species included in this section ... -
Biodiversity of Saccharomyces cerevisiae populations in Malbec vineyards from the “Zona Alta del Río Mendoza” region in Argentina
(Elsevier, 2011-12-15)The “Zona Alta del Río Mendoza” (ZARM) is the major Malbec grape viticulture region of Argentina. The aim of the present study was to explore Saccharomyces cerevisiae biodiversity in ZARM vineyards. Interdelta PCR and RFLP ... -
Blue light attenuation mediates morphological and architectural acclimation of Vitis vinifera cv. Malbec to shade and increases light capture
(2018-10)Grapevine is one of the most important fruit crops worldwide. Vineyard management practices affect light interception and spectral characteristics inside the canopy. Plant photoreceptors drive shade acclimation responses ... -
Caracterización de daños producidos por Meloidogyne Spp. (Nemata: Tylenchida) en la vid en Mendoza, Argentina
(Universidad de Nariño, 2014-12)El objetivo de esta investigación fue comparar y establecer relaciones entre los diferentes indicadores de crecimiento entre plantas de vid con dos niveles de infestación (alto y leve) de Meloidogyne spp. El estudio se ... -
Carbohydrate reserve status of Malbec grapevines after several years of regulated deficit irrigation and crop load regulation
(Wiley, 2013-10)Background and Aims: Regulated deficit irrigation (RDI) and bunch thinning are two viticultural practices applied worldwide. There is limited knowledge, however, about their combined effects on carbohydrate dynamics and ... -
Carotenoid profile produced by Bacillus licheniformis Rt4M10 isolated from grapevines grown in high altitude and their antioxidant activity
(2018-07)Bacillus licheniformis (BL) strains are used for industrial production of exoenzymes, antibiotics and secondary metabolites, and also serve as probiotics. Some strains sequester heavy metals, promoting plant growth or ... -
Changes in leaf stomatal conductance, petiole hydraulics and vessel morphology in grapevine (Vitis vinífera cv.Chasselas) under different light and irrigation regimes
(2017)Hydraulic conductance and water transport in plants may be affected by environmental factors, which in turn regulate leaf gas exchange, plant growth and yield. In this study, we assessed the combined effects of radiation ... -
Characterization of grapevine wood microbiome through a metatranscriptomic approach
(Springer, 2021-06-30)Grapevine trunk diseases threaten wine and table grape production worldwide, primarily by reducing yields and, in its advanced stages, causing plant death. Among those diseases, the complex etiology disease known as hoja ... -
Characterization of Lasiodiplodia species associated with grapevines in Mexico
(Mediterranean Phytopathological Union, 2021-10-05)Botryosphaeria dieback is one of the most prevalent grapevine trunk diseases (GTDs), and is caused by fungi in the Botryosphaeriaceae. Fungi invade grapevine vascular systems mainly through pruning wounds, and cause cankers ... -
Chemical, chromatic, and sensory attributes of 6 red wines produced with prefermentative cold soak
(2015-05-01)Six red grape cultivars, Barbera D’Asti, Cabernet Sauvignon, Malbec, Merlot, Pinot Noir and Syrah, were produced with or without prefermentative cold soak (CS). Cold soak had no effect on the basic chemical composition of ... -
