HydroShoot: a functional-structural plant model for simulating hydraulic structure, gas and energy exchange dynamics of complex plant canopies under water deficit—application to grapevine (Vitis vinifera)
(Oxford Academic Press, 2019-06)This paper presents HydroShoot, a leaf-based functional-structural plant model (FSPM) that simulates gas exchange rates of complex plant canopies under water deficit conditions. HydroShoot is built assuming that simulating ... -
Identification and recovery of local Vitis vinifera L. cultivars collected in ancient vineyards in different locations of Argentina
(Wiley, 2022-05)Abstract. Background and Aims: These last years, minor cultivars have gained attention as they provide an opportunity to offer original products in a global market and to combat global warming. Recent evidence brought to ... -
Identity and parentage of some South American grapevine cultivars present in Argentina
(2017)Background and Aims: Based on 19 nuclear simple sequence repeat markers and parental analysis, we aimed to identify and propose the pedigree of different accessions held at the Estación Experimental Agropecuaria Mendoza ... -
Impact of elevated temperature and water deficit on the chemical and sensory profiles of Barossa Shiraz grapes and wines
(Wiley, 2015-06)Background and Aims: Interactions are the main causes of complexity in field experiments; however, no studies have combined water and temperature regimes in field‐growing vines. Here we assessed grape and wine attributes ... -
In vitro cultures of Vitis vinifera L. cv. Chardonnay synthesize the phytoalexin nerolidol upon infection by Phaeoacremonium parasiticum
(2013)This study investigated terpene synthase (TPS) activity and terpene antifungal metabolites in calluses and cell suspension cultures of Vitis vinifera cv. Chardonnay infected with Phaecremonium parasiticum, one of the fungi ... -
Incidence of Grapevine Leafroll Associated Viruses -1, -2, and -3 in Mendoza vineyards
(2010-12)Viticulture is important in Argentina's economy, especially in the province of Mendoza, which is responsible for more than 75% of the crop cultivated area. In this work, we evaluated the incidence of Grapevine leafroll-associated ... -
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 ... -
Leaf carbohydrate metabolism in Malbec grapevines : combined effects of regulated déficit irrigation and crop load
(2016)Background and aims: Regulated deficit irrigation and crop load adjustment are viticultural practices used to improve grape and wine composition. Our objective was to evaluate the combined effect of irrigation and crop ... -
Mechanisms underlying photosynthetic acclimation to high temperature are different between Vitis vinifera cv. Syrah and Grenache
(CSIRO Publishing, 2020-12-07)Photosynthesis acclimation to high temperature differs among and within species. Grapevine intra-specific variation in photosynthetic acclimation to elevated temperature has been scarcely assessed. Our objectives were ... -
Método práctico de cría masiva de Lobesia botrana Den. & Schiff. (Lepidoptera: Tortricidae) en condiciones de laboratorio = A practical rearing method for Lobesia botrana Den. & Schiff. (Lepidoptera: Tortricidae) under laboratory conditions
(Sociedad Entomológica Argentina, 2016)Lobesia botrana Den. & Schiff. es plaga cuarentenaria de la Argentina. En el año 2010 se registró su aparición en Maipú, Mendoza. El estudio describe la técnica de cría de L. botrana sobre una dieta artificial. El objetivo ... -
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 ... -
Modulation of flavonoid biosynthetic pathway genes and anthocyanins due to virus infection in grapevine (Vitis viniferaL.) leaves
(BMC, 2010-08)Background: Symptoms of grapevine leafroll disease (GLRD) in red-fruited wine grape (Vitis vinifera L.) cultivars consist of green veins and red and reddish-purple discoloration of inter-veinal areas of leaves. The ... -
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 ... -
