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 ... -
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 ... -
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 ... -
Loss of anthocyanins and modification of the anthocyanin profiles ingrape berries of Malbec and Bonarda grown under high temperature conditions
(2017)Malbec and Bonarda are the two most widely cultivated grape varieties in Argentina, and their derivedred wines are recognized worldwide, being their intense color a major quality trait. The temperature dur-ing fruit ripening ... -
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 ... -
Nudo gordiano en la evolución del comportamiento proambiental. La brecha entre el saber y el hacer en el cambio de hábitos de consumo.
(Universidad de Málaga, 2021)El presente trabajo comienza con información básica y relevante sobre el cambio climático y sus consecuencias. Se mencionan brevemente teorías que intentan explicar las características del comportamiento proambiental y el ... -
Olas de calor : efecto sobre la fecha de brotación, el crecimiento de brotes y los tejidos conductores de agua en plantas de vid cv.Malbec
(2014)El artículo presenta los resultados de un ensayo realizado en la EEA Mendoza INTA relacionado con el cambio climático. Se evaluaron los efectos que pueden tener las olas de calor, ocurridas antes de la brotación, sobre ... -
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 ... -
La poda tardía como estrategia de adaptación al cambio climático en la variedad Malbec (Vitis vinifera) en Mendoza, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2023)Las temperaturas más altas en los últimos años han generado un avance en la madurez de las bayas y han reducido el número de días a cosecha. También ha generado un desacople entre la acumulación de azúcar respecto a las ... -
Spring reproductive and vegetative phenology of olive (Olea europaea L.) cultivars at different air temperatures along a latitudinal-altitudinal gradient in Argentina
(Elsevier, 2022-10)Detailed spring phenology studies are scarce in olive trees growing in non-Mediterranean climates despite crop expansion into new regions in the last few decades. Additionally, the vegetative phenology of olive trees has ... -
Syrah and Grenache (Vitis vinifera) revealed different strategies to cope with high temperature
(Australian Society of Viticulture and Oenology, 2022-03-02)Background and Aims: Global warming will threaten vineyard sustainability in warm and arid regions. Therefore, increasing water use efficiency (WUE) is essential for long-term viticulture sustainability. Nevertheless, ... -
Temperaturas previas y aclimatación en yemas florales de duraznero [Prunus persica (L.) Batsch.] expuestas a congelación
(Universidad de Colima, 2018-05)Los árboles frutales caducifolios poseen un periodo de reposo durante el invierno, que les permite tolerar temperaturas bajas extremas con un mínimo de actividad, minimizando también el daño a sus órganos. Durante este ... -
Thermal history parameters drive changes in physiology and cold hardiness of young grapevine plants during winter
(Elsevier, 2018-11)Vitis vinifera is mainly cultivated in temperate areas, where seasons are well defined and winter conditions might be severe. To survive under these conditions during the dormant season, grapevines sense environmental ...
