Seasonal leaf gas exchange and water potential in a woody cerrado species community
Predawn leaf water potential (Ypd) and morning values of leaf gas exchange, as net photosynthesis (A), stomatal conductance (gs), transpiration (E), and morning leaf water potential (Ymn) wereExpand

Photosynthetic responses of tropical tree species from different successional groups under contrasting irradiance conditions
This study evaluated the photosynthetic responses of seven tropical trees of different successional groups under contrasting irradiance conditions, taking into account changes in gas exchange andExpand

Anatomical and biochemical characterization of the calcium effect on Eucalyptus urophylla callus morphogenesis in vitro
Calcium chloride concentrations from 0.0 to 12.12 mM were added to the culture medium and calcium content in calluses were determined directly by X-ray fluorescence spectrometry, a non-destructiveExpand

WATER DEFICIENCY AT DIFFERENT DEVELOPMENTAL STAGES OF GLYCINE MAX CAN IMPROVE DROUGHT TOLERANCE ( 1 )
Developmental windows are specific periods of sensitivity during normal plant development in which a perturbation may be adaptively integrated. In these periods, sub-lethal environmentalExpand

Chlorophyll fluorescence of tropical tree species in a semi-deciduous forest gap
ABSTRACT - The characterization of different ecological groups in a forest formation/succession is unclear. Tobetter define the different successional classes, we have to consider ecophysiologicalExpand

Plant “electrome” can be pushed toward a self-organized critical state by external cues: Evidences from a study with soybean seedlings subject to different environmental conditions
ABSTRACT In the present study, we have investigated how the low-voltage electrical signals of soybean seedlings change their temporal dynamic under different environmental conditions (cold, lowExpand

Using network connectance and autonomy analyses to uncover patterns of photosynthetic responses in tropical woody species
abstract Daily courses of leaf gas exchange and chlorophyll fluorescence in forest gap and under-storey environments were used to build photosynthetic networks in two pioneers and twolate-successionalExpand

Biomass and bioenergy partitioning of sugarcane plants under water deficit
This study assessed the photosynthesis, biomass, and phytoenergy production in sugarcane plants subjected to water deficit during the initial stages of development. We hypothesize that theExpand

Photosynthetic limitations caused by different rates of water-deficit induction in Glycine max and Vigna unguiculata
Plants are constantly subjected to variations in their surrounding environment, which affect their functioning in different ways. The influence of environmental factors on the physiology of plantsExpand

Functional groups of forest succession as dissipative structures: an applied study.
This study tested the hypothesis that dissipative efficiency of tropical tree species could be an ecological advantage in the forest succession process. Daily leaf gas exchanges of a pioneer speciesExpand
