Photochemistry and hydric responses of congeneric Croton species at restoration sites under dry season: implications for species selection
(2019-06-15)
The success of the ecological restoration depends on the appropriate determination of species for implantation in restoration areas. The use of physiological performance as a criterion may help in the selection of species ...
Leaf morphophysiology of a Neotropical mistletoe is shaped by seasonal patterns of host leaf phenology
(2016-04-01)
Several mistletoe species are able to grow and reproduce on both deciduous and evergreen hosts, suggesting a degree of plasticity in their ability to cope with differences in intrinsic host functions. The aim of this study ...
Chronic ulcerative stomatitis: A systematic review of the clinical and microscopic features
(2019-11-01)
Background: the purpose of this study was to perform a systematic review regarding clinical and histopathological characteristics, immunopathological findings, and treatment for chronic ulcerative stomatitis (CUS). Material ...
Effects of potassium and sodium supply on drought-adaptive mechanisms in Eucalyptus grandis plantations
(Wiley-Blackwell, 2014-07-01)
A basic understanding of nutrition effects on the mechanisms involved in tree response to drought is essential under a future drier climate. A large-scale throughfall exclusion experiment was set up in Brazil to gain an ...
Physiological changes associated with antioxidant enzymes in response to sugarcane tolerance to water deficit and rehydration
(2014)
Water deficit is the main limiting factor for sugarcane yield worldwide. Under this stress, the crop develops adaptive mechanisms that participate in maintaining the plants’ water status. A better understanding of these ...
Gas exchange in lisianthus plants (Eustoma grandiflorum) submitted to different doses of nitrogen
(Acad Sci Czech Republic, Inst Experimental Botany, 2005-01-01)
The effect of different doses of nitrogen (N) on gas exchange, relative chlorophyll (Chl) amount, and the content of N in the aerial biomass of lisianthus was evaluated. The treatments consisted of six different concentrations ...
Respostas fisiológicas de cultivares de cana-de-açúcar submetidas à deficiência hídrica e a reidratação
(2013-12-01)
The aim of this work was to study the physiological responses of three contrasting cultivars of sugar cane subject to water stress and rewatering, The experiment was carried out in a greenhouse, where the cultivars SP83-2847, ...
Photosynthetic responses and proline content of mature and young leaves of sunflower plants under water deficit
(2006-03-01)
In mature and young leaves of sunflower (Helianthus annuus L. cv. Catissol-01) plants grown in the greenhouse, photosynthetic rate, stomatal conductance, and transpiration rate declined during water stress independently ...
Características fotossintéticas de genótipos de capim-elefante anão (Pennisetum purpureum Schum.), em estresse hídrico
(2010-04-19)
The experiment was carried out aiming to evaluate the gas exchange of dwarf elephant grass genotypes under different hydric conditions, in a randomized design with three replications. Genotypes of dwarf elephant grass ...
