Changes in leaf stomatal conductance, petiole hydraulics and vessel morphology in grapevine (Vitis vinífera cv.Chasselas) under different light and irrigation regimes
(2017)Hydraulic conductance and water transport in plants may be affected by environmental factors, which in turn regulate leaf gas exchange, plant growth and yield. In this study, we assessed the combined effects of radiation ... -
Comportamiento isohídrico o anisohídrico en vides…. ¿Una controversia sin fin?
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)De acuerdo al tipo de respuesta estomática, muchas especies han sido clasificadas como isohídricas o anisohídricas. Las plantas isohídricas son aquellas que cierran sus estomas cuando sensan una caída en el potencial hídrico ... -
Differential growth of hybrid pine families in Misiones, Argentina, is not linked to their stomatal behavior
(Sociedad Argentina de Fisiología Vegetal, 2021-09-13)INTA-PINDO hybrid pine is the result of the crossing between Pinus elliottii var. elliottii and Pinus caribaea var. hondurensis. The aim of this study was to analize variables that can explain the differential growth between ... -
Efecto de la restricción hídrica invernal en olivo (Olea europaea L.): el potencial hídrico xilemático y la conductancia estomática
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-08)Durante la aplicación de una restricción hídrica invernal, en las temporadas de 2011 y de 2012, se cuantificaron y relacionaron el estado hídrico del olivo (Olea europaea L.) con el contenido de humedad del suelo y la ... -
Interaction of light and water stress on the ecophysiological response of Nothofagus antarctica (G. Forster) Oerst.
(Instituto de Ciências Agrárias e Ambientais Mediterrânicas da Universidade de Évora, 2014-09-30)Nothofagus antarctica (G. Forster) Oerst. (ñire) occupies a latitudinal gradient ranged from 36° 30´ to 56° 00’ S, and extends from sea level to 2,000 m a.s.l. It is the species with widest ecological amplitude in Nothofagus ... -
Mapping a region within the 1RS.1BL translocation in common wheat affecting grain yield and canopy water status
(Springer, 2014-12)The translocation of the short arm of rye (Secale cereale L.) chromosome one (1RS) onto wheat (Triticum aestivum L.) chromosome 1B (1RS.1BL) is used in wheat breeding programs worldwide due to its positive effect on yield, ... -
Mesophyll conductance modulates photosynthetic rate in cotton crops exposed to heat stress under field conditions
(Wiley, 2021-08)Cotton is often exposed to high temperatures during the reproductive stage, which can negatively affect its productivity. The objectives were to: i) test whether heat stress impacts during the reproductive stage on ... -
Photosynthetic response to different light intensities, water status and leaf age of two Berberis species (Berberidaceae) of Patagonia steppe, Argentina.
(Elsevier, 2011-11)Net photosynthetic rate (A) and stomatal conductance (gs) from leaves of Berberis buxifolia and Berberis heterophylla saplings were measured under different conditions of radiation and water availability and for leaves of ... -
Relaciones entre cavitación y cierre estomático en vides sometidas a déficit hídrico
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo., 2011)La cavitación es una disfunción fisiológica que ocurre en el xilema de las plantas cuando estas están bajo déficit hídrico, y que entraña una pérdida de su conductancia hidráulica (kL), cuando algunos vasos se llenan de ... -
Responses in growth and physiological traits in two Populus × canadensis clones (‘I-214’ and ‘I-488’) submitted to different irrigation frequencies in central Chile
(Elsevier, 2019-10-01)Water is the main limiting factor for poplar plantations in the Mediterranean zone of central Chile. Overall, water requirements in these plantations may be estimated using climatic and soil moisture data. However, irrigation ... -
Respuesta anatómica y fisiológica de especies de Nothofagus de Patagonia austral ante la variación de temperatura, humedad, CO2 y nutrientes
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2021-04-05)Tomando los bosques nativos de Nothofagus de la Patagonia austral como objeto de estudio, se han desarrollado diversas investigaciones en los distintos capítulos de la tesis, para evaluar la respuesta de estas especies ... -
Root hydraulic conductivity and adjustments in stomatal conductance: hydraulic strategy in response to salt stress in a halotolerant species
(Oxford University Press, 2015-11)Recent advances at the molecular level are introducing a new scenario that needs to be integrated into the analysis of plant hydraulic properties. Although it is not yet clear to what extent this scenario alters the current ... -
Seedling drought stress susceptibility in two deciduous Nothofagus species of NW Patagonia
(2010-06)The physiological capacities of seedlings to cope with drought may be subject to strong selective pressure in the context of future climate scenarios, threatening the regeneration and sustainability of forests. Characterization ... -
Stomatal behavior of different grapevine cultivars in response to soil water status and air water vapor pressure deficit
(International Viticulture and Enology Society (IVES), 2010-03)Aims: Genetic variability in grapevine cultivars may influence their strategy to cope with drought through stomatal regulation of transpiration rate. The aim of the present study was to evaluate the stomatal sensitivity ... -
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, ... -
The phenomenon of cavitation in grapevine… Unravelling implicated mechanisms = El fenómeno de la cavitación en vid… Descifrando los mecanismos implicados
(Universidad Nacional de Cuyo, 2018)Cavitation is a physiological dysfunction that takes place in the xylem of water stressed plants. It leads to a loss of hydraulic conductance (kL)as the vessels are filled with air. This impacts water supply, water potential ... -
