Estudio de las relaciones hídricas foliares de amaranto (amaranthus cruentus l.) bajo riego deficitario en Alhué y Longotoma
(Universidad de Chile, 2022)
El amaranto es un cultivo descrito como tolerante al déficit hídrico, por lo que puede ser
considerado como una alternativa para zonas de sequía. Para seleccionar los genotipos mejor
adaptados al déficit hídrico es ...
Different drought‑adaptive capacity of a native Patagonian tree species (Nothofagus pumilio) resulting from local adaptation
(Springer, 2021-06)
The resistance of different genotypes to abiotic stress may be due to genetic effects and/or to phenotypic plasticity allowing them to acclimate to variable conditions. The contribution of one or the other mechanism ...
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 ...
Parâmetros fisiológicos como indicadores de tolerância à seca em clones de Eucalyptus spp.
(Universidade Estadual Paulista (Unesp), 2019-06-17)
Dentre os principais atributos do sucesso de qualquer empreendimento florestal está a escolha correta dos genótipos a serem utilizados. Portanto, identificar parâmetros fisiológicos que contribuam para a tolerância à seca ...
Hydraulic architecture and photoinhibition influence spatial distribution of the arborescent palm Euterpe edulis in subtropical forests
(Oxford University Press, 2014-06)
Physiological characteristics of saplings can be considered one of the most basic constraints on species distribution. The shade-tolerant arborescent palm Euterpe edulis Mart. is endemic to the Atlantic Forest of Argentina, ...
Crescimento de Plectranthus barbatus Andr. sob estresse hídrico
(Universidade Federal de Mato GrossoBrasilFaculdade de Agronomia e Zootecnia (FAAZ)UFMT CUC - CuiabáPrograma de Pós-Graduação em Agricultura Tropical, 2021-04-06)
The water stress is one of the main factors that alter the plant metabolism
and affects its development. In order to verify the effects of water stress on the growth of
the species Plectranthus barbatus Andrews, seedlings ...
Water relations and hydraulic architecture in Cerrado trees: adjustments to seasonal changes in water availability and evaporative demandRelações hídricas e arquitetura hidráulica em árvores do cerrado: adequação às variações sazonais de disponibilidade hídrica e de demanda evaporativa
(Brazilian Society of Plant Physiology, 2008-09)
We determined adjustments in physiology and morphology that allow Neotropical savanna trees from central Brazil (Cerrado) to avoid water deficits and to maintain a nearly constant internal water balance despite seasonal ...
Stem and leaf hydraulics of congeneric tree species from adjacent tropical savanna and forest ecosystems
(Springer, 2008-12)
Leaf and stem functional traits related to plant water relations were studied for six congeneric species pairs, each composed of one tree species typical of savanna habitats and another typical of adjacent forest habitats, ...
