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 ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
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 ... -
Monitoring of killer yeast populations in mixed cultures: influence of incubation temperature of microvinifications samples
(2012-11)Killer yeasts are frequently used to combat and prevent contamination by wild-type yeasts during wine production and they can even dominate the wine fermentation. Stuck and sluggish fermentations can be caused by an ... -
Persistence and reservoirs of Saccharomyces cerevisiae biodiversity in different vineyard niches
(Elsevier, 2019-09)Highlights: S. cerevisiae vineyard populations dynamically changed during grape growth cycle. Strains from ripe grapes showed highest diversity and distribution across vineyard. Buds in winter and bark from sprouting to ... -
Photosynthetic acclimation to high temperature in Syrah and Grenache
(Science & Wine, CV, Lda, 2021-03-28)The main objective of this study was to evaluate (i) the mechanisms underlying the long-term acclimation of photosynthesis to elevated temperature and (ii) to determine whether these responses are similar among Syrah and ... -
Review: critical appraisal of methods to investigate the effect of temperature on grapevine berry composition
(Wiley, 2015-02)The grapevine is an economically important crop and a model species of long‐lived perennials widely used in bioclimatic studies. Ambient temperature modulates berry composition, hence the significant research effort in ... -
Selection of indigenous Saccharomyces cerevisiae strains to ferment red musts at low temperature
(2012-03)The aim of this work was to select native Saccharomyces cerevisiae strains to conduct the alcoholic fermentation of red must at low temperature (15°C), thus producing volatile compounds that enhance the aromatic profile ... -
Whole plant open chamber to measure gas exchange on herbaceous plant
(2016)Much of our understanding about CO2 and H2O gas exchange in plants has been gained from studies at leaf level. Extrapolation of results to whole plant is difficult and not always accurate. In order to overcome this limitation, ...
