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 ... -
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 ... -
Comparación de las respuestas al estrés hídrico y salino de los portainjertos de vid 1103P y 101-14Mgt, injertados con Cabernet Sauvignon = Comparing water deficit and saline stress between 1103P and 101-14Mgt rootstocks, grafted with Cabernet Sauvignon
(2017)En zonas áridas bajo riego, los viñedos enfrentan condiciones de déficit hídrico y salinidad. Como frecuentemente estos factores de estrés ocurren simultáneamente, es difícil evaluar la gravedad relativa de cada uno de ... -
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 ... -
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 ... -
Fruit-localized photoreceptors increase phenolic compounds in berry skins of field-grown Vitis vinifera L. cv. Malbec
(2015-02)Sunlight exposure has multiple effect on fruits, as it affects the light climate perceived by fruit photoreceptors and fruit tissue temperature. In grapes (Vitis vinifera L.), light exposure can have a strong effect on ... -
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. ... -
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 ... -
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 ... -
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 ...
