Dynamics of cavitation in a Douglas-fir tree-ring: transition-wood, the lord of the ring?
(INRA, 2014-11)The objective of this work wa s to investigate the dynamics of embolism formation within a Douglas fir tree ring . Four resistant and four vulnerable 10 year old trees were selected among 50 trees, based on their P 50 . ... -
Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density
(Oxford University Press, 2018-02)Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry ... -
Narrow vessels cavitate first during a simulated drought in Eucalyptus camaldulensis
(Wiley, 2021-09-15)Establishing drying-limits for mortality of different tree species and understanding the anatomical and physiological traits involved is crucial to predict forests' responses to climate change. The xylem of Eucalyptus ... -
New insights into wood anatomy and function relationships: how Eucalyptus challenges what we already know
(Elsevier, 2019-12-15)Multispecies surveys have shown that there is a weak but significant trade-off between xylem efficiency and safety in woody species, with no species maximizing both attributes at the same time. Relationships between xylem ... -
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 ... -
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 ... -
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 ... -
Wood structure, xylem functionality and growth of six Salix clones in two sites with different environmental stress in Argentina
(Sociedade de Investigações Florestais, 2018)The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype (clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years), and the impact ...
