The widely used theory for gas exchange proposed by von Caemmerer and Farquhar (vCF) integrates molar fluxes, mole fraction gradients and ternary effects but does not account for cuticular fluxes, for...
Stomata control the gas exchange of terrestrial plant leaves, and are therefore essential to plant growth and survival. We investigated gas exchange responses to vapor pressure deficit (VPD) in two gr...
Guard cells perceive external and internal stimuli and regulate stomatal conductance in plants. With the use of gas exchange analyzers, time-resolved stomatal conductance responses to light intensity,...
Mycorrhizal fungi form mutualistic symbioses with the roots of 80% of plants which increase growth and nutrient uptake for the host plants. This research was conducted to determine the effect of indiv...
To evaluate the lead tolerance of Populus euramericana (Dode) Guinier 561/41 and Populus nigra Linnaeus 63/135 clones in relation to photosynthetic efficiency, we measured physiological parameters of ...
The effects of photosynthetic photon flux density (PPFD) and temperature on leaf gas exchange rates of ten lines of Saccharum spontaneum L. collected from the tropics to temperate regions in North-Wes...
Effects of water stress on gas exchange characteristics were investigated in a crassulacean acid metabolism plant, Dendrobium Ekapol cv. Panda when water was withheld from pot. The diurnal CO2 exchan...
Effects of growth day length on gas exchange characteristics were investigated in a crassulacean acid metabolism (CAM) plant, Dendrobium Ekapol cv. Panda. Long (16h) and short (10h) day lengths were t...
We measured stomatal frequency and guard cell length in the Gramineae and compared these components among the photosynthetic types and/or the subfamilies. The mean stomatal frequency of the Eragrostoi...
Mangrove trees have been considered to possess a higher carbon fixation capacity than terrestrial trees although a reliable method to estimate their CO2 fixation capacity has not been established. In ...
Coronatine is a phytotoxin that affects the accumulation of defence-related metabolites in plants but information on how its effects may be mediated by environmental stress is scanty. An experiment wa...
Effects of nitrogen (N) deficiency on photosynthetic gas exchange and photosystem II (PSII) photochemistry of flag leaves during grain-filling stage were investigated in six rice cultivars, Kasalath (...
The objective of this study was to establish the correlation of the chlorophyll meter (SPAD) readings with the contents of chlorophyll (Chl) and ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisc...
This study was conducted to clarify the genotypic differences in diurnal variations in leaf gas exchange characteristics and the effect of irrigation levels, growth stages and cultivars on leaf water ...
