Physiological regulation and efficient xylem water transport regulate diurnal water and carbon balances of tropical lianas
(Wiley Blackwell Publishing, Inc, 2017-02)
Tropical lianas deploy most of their leaves towards the top of the forest canopy, whereas trees exhibit a more stratified crown. Forest canopies are often exposed to hot and windy conditions, and how lianas cope with the ...
Anatomia, densidade e condutividade hidráulica potencial do xilema secundário de árvores de três procedências de Balfourodendron riedelianum (Engl.) Engl. (Rutaceae) em plantios homogêneos
(Universidade Estadual Paulista (Unesp), 2018-02-28)
Estudos intraespecíficos com procedências replicadas em diferentes locais permitem distinguir o efeito do genótipo e do ambiente no crescimento e na estrutura anatômica das plantas. Diante das previsões de intensificação ...
The spatial distribution of phosphate in the root system modulates N metabolism and growth in Eucalyptus grandis young plants
(Springer, 2017-02)
Key message: High P homogeneously applied in roots reduced growth and nitrate uptake. High P in a patch reduced N in tissues but did not reduce growth, because root hydraulic conductivity increased. Abstract: Little is ...
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 . ...
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 ...
Examining physiological, water relations, and hydraulic vulnerability traits to determine anisohydric and isohydric behavior in almond (Prunus dulcis) cultivars: Implications for selecting agronomic cultivars under changing climate
(Frontiers, 2022)
The search for drought tolerant species or cultivars is important to address water scarcity caused by climate change in Mediterranean regions. The anisohydric–isohydric behavior concept has been widely used to describe ...
Nutrient enrichment changes water transport structures of savanna woody plants
(IOP Publishing, 2021-02)
Brazilian savanna is a seasonally dry biome, highly diverse and distributed mainly on nutrient-limited soils. Interactions between water stress and nutrient availability are important evolutionary filters in these environments. ...
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 ...
