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 ...
Proposed pre-selection method for identification of dwarfing peach rootstocks based on rapid shoot xylem vessel analysis
(Scientia Horticulturae, 2018)
Genetic variation of xylem hydraulic properties shows that wood density is involved in adaptation to drought in Douglas-fir (Pseudotsuga menziesii (Mirb.))
(Springer, 2011-05)
Relationships between wood density and hydraulic efficiency and safety (hydraulic specific conductivity and vulnerability to cavitation, respectively) could clarify the physiological process explaining the impact of density ...
Removal of nutrient limitations in forest gaps enhances growth rate and resistance to cavitation in subtropical canopy tree species differing in shade tolerance
(Oxford University Press, 2013-02)
A 4-year fertilization experiment with nitrogen (N) and phosphorus (P) was carried out in natural gaps of a subtropical forest in northeastern Argentina. Saplings of six dominant canopy species differing in shade tolerance ...
Prediction of hydraulic conductivity loss from relative water loss: new insights into water storage of tree stems and branches
(Wiley, 2019-04)
More frequently occurring, drought waves call for a deeper understanding of tree hydraulics and fast and easily applicable methods to measure drought stress. The aim of this study was to establish empirical relationships ...
Why are Chloris gayana leaves shorter in salt-affected plants? Analyses in the elongation zone
(Society for Experimental Biology, 2006-11)
Reduced hydraulic conductance calculated from growth data was suggested to be the main reason for reduced leaf expansion in salt-stressed Chloris gayana (Rhodes grass). In this work, xylem vessel cross-sections and wall ...
Secondary xylem of stem and root of cerrado woody plants: anatomical and functional approach
(Universidade Estadual Paulista (Unesp), 2021-10-08)
The plant's ability to invest in the wood tissue in different organs is crucial to its survival in terrestrial environments. Wood is a complex system linked to water transport, mechanical support, and storage of essential ...
Contrasts in xylem hydraulics and water use underlie the sorting of different sand-fixing shrub species to early and late stages of dune stabilization
(Elsevier Science, 2020-02)
Dominating sand-fixing shrubs play crucial roles in the stabilization and rehabilitation of sand dunes. Different sandfixingshrub species often separate along the temporal-spatial environmental gradient during the sand ...
