Optimal stomatal behavior theory for simulating stomatal conductance [PDF]

open access: yesChinese Journal of Plant Ecology, 2016
Among the most critical processes in simulating terrestrial ecosystem performance is the regulatory role of sto- mata in carbon and water cycles. Compared with field measurements, the changes in stomatal slope caused by the biophysical environment provide a simple but effective synthetic framework for studying climate-related carbon and water cycling ...

Stomatal Conductance of Differentially Salinized Plants [PDF]

open access: yesPlant Physiology, 1972
Stomatal resistance was measured daily with a stomatal diffusion porometer during a 4-week period in leaves of bean (Phaseolus vulgaris L., var. Bush Blue Lake) and barley (Hordeum vulgare L., var. Liberty) plants having roots equally split between two differentially salinized nutrient solutions.

Effects of the antiozonant ethylenediurea (EDU) on Fraxinus ornus L.. The role of drought [PDF]

open access: yes, 2017
Ethylenediurea (EDU) is a synthetic chemical known to protect plants from the phytotoxic effects of tropospheric ozone (O3). Although many studies have proposed the use of EDU for studying the O3 effects under field conditions, its mechanism of action is

Responses of leaf stomatal and mesophyll conductance to abiotic stress factors

open access: yesJournal of Integrative Agriculture, 2022
Plant photosynthesis assimilates CO2 from the atmosphere, and CO2 diffusion efficiency is mainly constrained by stomatal and mesophyll resistance. The stomatal and mesophyll conductance of plants are sensitive to abiotic stress factors, which affect the ...

Oscillations in Stomatal Conductance [PDF]

open access: yesPlant Physiology, 1974
It is supposed that oscillations in stomatal conductance are associated with the dynamic properties of the loop in which rate of evaporation affects, through physiological processes, the aperture of stomata and stomatal aperture in turn affects rate of evaporation.

Systemic Signaling in the Regulation of Stomatal Conductance [PDF]

open access: yesPlant Physiology, 2020
Dear Editor, Plants use systemic signaling networks to spread information on locally perceived stimuli and coordinate responses in different plant parts. In natural environments, sun flecks and leaf-shading may lead to rapid and large changes in light conditions within the canopy and plants need ...

Optimization of leaf morphology in relation to leaf water status: A theory. [PDF]

open access: yes, 2020
The leaf economic traits such as leaf area, maximum carbon assimilation rate, and venation are all correlated and related to water availability. Furthermore, leaves are often broad and large in humid areas and narrower in arid/semiarid and hot and cold ...

Stomatal responses of tree species from the cloud forest in central Veracruz, México

open access: yesBotan‪ical Sciences, 2016
Stomatal conductance is considered as a key plant response because it plays an important role in plant physiology by controlling transpiration (water status) and CO2 assimilation, regulating plant productivity.

Predicting photosynthesis and transpiration responses to ozone: decoupling modeled photosynthesis and stomatal conductance [PDF]

open access: yesBiogeosciences, 2012
Plants exchange greenhouse gases carbon dioxide and water with the atmosphere through the processes of photosynthesis and transpiration, making them essential in climate regulation.
