Biophysical properties and functional significance of stem water storage tissues in Neotropical savanna trees
(Wiley Blackwell Publishing, Inc, 2007-12)
Biophysical characteristics of sapwood and outer parenchyma water storage compartments were studied in stems of eight dominant Brazilian Cerrado tree species to assess the impact of differences in tissue capacitance on ...
Coordination of leaf and stem water transport properties in tropical forest trees
(Springer, 2008-05)
Stomatal regulation of transpiration constrains leaf water potential (ΨL) within species-specific ranges that presumably avoid excessive tension and embolism in the stem xylem upstream. However, the hydraulic resistance ...
Temporal dynamics of stem expansion and contraction in savanna trees: withdrawal and recharge of stored water
(Oxford University Press, 2008-12)
Relationships between diel changes in stem expansion and contraction and discharge and refilling of stem water storage tissues were studied in six dominant Neotropical savanna (Cerrado) tree species from Central Brazil. ...
Water Storage Discharge and Refilling in the Main Stems of Canopy Tree Species Investigated Using Frequency Domain Reflectometry and Point Electronic Dendrometers
(International Society for Horticultural Science, 2013-03)
Water storage in the trunks of large trees plays an important role in whole-plant water balance on both daily and seasonal bases. To investigate the dynamics of water storage and usage in tree trunks, diurnal changes in ...
Water storage dynamics in the main stem of subtropical tree species differing in wood density, growth rate and life history traits
(Oxford University Press, 2014-11)
Wood biophysical properties and the dynamics of water storage discharge and refilling were studied in the trunk of canopy tree species with diverse life history and functional traits in subtropical forests of northeast ...
Functional Diversity in Tropical High Elevation Giant Rosettes
(Goldstein G, Santiago LS (Eds). Tropical Tree Physiology. Springer.Suiza, 2017)
Stem aquaporins and surfactant-related genes are differentially expressed in two Eucalyptus species in response to water stress
(2021-01-01)
The regulation of water column tension in the xylem is essential to avoid embolism formation. Plants can actively reduce the hydraulic resistance in the xylem by moving water from the neighbourhood living cell, via aquaporins. ...
Análogo hídrico-elétrico do caule de Phaseolus vulgaris L. com capacitância hídrica variável
(Universidade Federal de Mato GrossoBrasilInstituto de Física (IF)UFMT CUC - CuiabáPrograma de Pós-Graduação em Física Ambiental, 2020-11-11)
In the context of the hydric-electric analogy, hydrics capacitances are treated as
constant throughout the soil-plant-atmosphere continuum (SPAC). In particular, on the
stem, results from experimental studies that ...
Strong hydraulic segmentation and leaf senescence due to dehydration may trigger die-back in Nothofagus dombeyi under severe droughts: a comparison with the co-occurring Austrocedrus chilensis
(Springer Verlag Berlín, 2014-07-20)
Die-back was observed in South America temperate forests during one of the most severe droughts of the 20th century (1998–1999). During this drought Austrocedrus chilensis trees survived, whereas trees of the co-occurring ...
Constraints on physiological function associated with branch architecture and wood density in tropical forest trees
(Oxford University Press, 2008-12)
This study examined how leaf and stem functional traits related to gas exchange and water balance scale with two potential proxies for tree hydraulic architecture: the leaf area:sapwood area ratio (AL:AS) and wood density ...
