Ajuste de modelo fenológico para predecir el comportamiento de Lobesia botrana (Lepidoptera: Tortricidae) en un viñedo de Mendoza, Argentina
(2015-12-00)La temperatura es la variable que más incide en el desarrollo de Lobesia botrana (Den & Schiff), cuya relación ha sido estudiada mediante modelos matemáticos, como el de Touzeau. En Mendoza, en 2010 se registró la aparición ... -
Chemical and chromatic effects of fermentation temperature on three clones of Pinot noir over two consecutive vintages
(American Society for Enology and Viticulture (ASEV), 2022-10-14)Three different Pinot noir clones (115, 777, and 828) from the Central Coast of California were subjected to different maceration temperature regimes for 14 days using triplicate fermentations (Cold: 10°C; Hot: 25°C; and ... -
Coeficiente fototermal del melón y su relación con la concentración de azucares en los frutos = Photothermal quotient in melon and its relationship with the fruits sugar concentration
(2015)El objetivo de este trabajo fue evaluar el efecto de la radiación y la temperatura a través de un cociente fototermal sobre la acumulación de azúcar en melón. Se realizaron experimentos al aire libre en tres años consecutivos, ... -
Combined effect of temperature and ammonium addition on fermentation profile and volatile aroma composition of Torrontés Riojano wines
(2018-01)The effects of process temperature and ammonium supplementation on fermentation profile, volatile aroma composition and wine sensory characteristics were evaluated in Torrontés Riojano (Vitis vinifera L.) wines from Mendoza ... -
Culture-dependent and independent techniques applied to monitor yeast species on cold soak at different temperatures in winemaking
(2016)Transformation of grape must into wine is a process that may vary according to the consumers' requirements. Application of cold soak prior to alcoholic fermentation is a common practice in cellars in order to enhance flavor ... -
Determinación de los requerimientos térmicos otoño-invernales en almendro (Prunus amygdalus Batsch) cv. Guara y cv. Marinada
(Universidad de Colima, México, 2022)Objetivo: determinar en almendros cv. Guara y cv. Marinada la fecha de transición entre endodormancia y ecodormancia, y los requerimientos de frío y de calor para la salida del reposo otoño-invernal. Materiales y ... -
Determinación del requerimiento de frío y de calor en duraznero [Prunus persica (L.) Batsch.] mediante un modelo de correlación
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-12)Los árboles frutales de hoja no persistente poseen un período de reposo entre los ciclos vegetativos. Para salir de reposo invernal, las yemas deben acumular primero frío (endodormancia) y luego calor (ecodormancia). El ... -
Efectos de las temperaturas primaverales sobre la fecha de cosecha del ajo
(EEA La Consulta, INTA, 2015)Es sabido que luego de la inducción foto termo periódica para que las plantas de ajos inicien la bulbificación, la única dueña de la situación a partir de allí es la temperatura y seguramente de ella dependerá la velocidad ... -
Effect of different closure types and storage temperatures on the color and sensory characteristics development of Argentinian Torrontes Riojano white wines aged in bottles
(Elsevier, 2021-06)During aging, most bottled white wines lose their distinctive organoleptic characteristics according to their storage conditions (closure, temperature, time). However, the effect of these factors on organoleptic characteristics ... -
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 low temperature fermentation on the yeast-derived volatile aroma composition and sensory profile in Merlot wines
(Elsevier, 2021-02)Different winemaking practices have been tried to improve wine quality and differentiate wine styles. Low temperature fermentation has been proposed to enhance the aroma profile in young red wines. The aim of this work was ... -
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 ... -
High Temperature Alters Anthocyanin Concentration and Composition in Grape Berries of Malbec, Merlot, and Pinot Noir in a Cultivar-Dependent Manner
(MDPI, 2022-03)Climate is determinant for grapevine geographical distribution, berry attributes, and wine quality. Due to climate change, a 2–4 °C increase in mean diurnal temperature is predicted by the end of the century for the most ... -
High temperature during the budswell phase of grapevines increases shoot water transport capacity
(Elsevier, 2020-09)Knowledge about heat acclimation in perennial plants is limited. Our hypotheses were (i) that high temperature during budswell before budbreak elicits acclimation in grapevines that is mediated by greater water transport ... -
How temperatures may affect the synthesis of fatty acids during olive fruit ripening: genes at work in the field
(MDPI, 2023-01)A major concern for olive cultivation in many extra-Mediterranean regions is the adaptation of recently introduced cultivars to environmental conditions different from those prevailing in the original area, such as the ... -
Impact of closure type and storage temperature on chemical and sensory composition of Malbec wines (Mendoza, Argentina) during aging in bottle
(Elsevier, 2019-07)Malbec is the flagship variety of Argentina mainly due to its high oenological value and plasticity to obtain different wine styles. During bottled aging, the chemical and organoleptic composition of wines is subject to ... -
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 ... -
Influence of irrigation regime and seasonal temperatures on nut quality and the oil fatty acid profile of walnuts (Juglans regia L.)
(Elsevier, 2023-08)Walnut production is expanding worldwide due to the high demand for natural products with proven nutraceutical properties. This expansion includes new growing areas, such as central–western Argentina, where crop water ... -
