Dynamics of canopy stomatal conductance, transpiration, and evaporation in a temperate deciduous forest, validated by carbonyl sulfide uptake [PDF]
Biogeosciences, 2017 Stomatal conductance influences both photosynthesis and transpiration, thereby coupling the carbon and water cycles and affecting surface–atmosphere energy exchange.

Optimal stomatal behavior theory for simulating stomatal conductance [PDF]
Chinese 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 ...

Optimization of leaf morphology in relation to leaf water status: A theory. [PDF]
, 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 Conductance of Differentially Salinized Plants [PDF]
Plant 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.

Responses of leaf stomatal and mesophyll conductance to abiotic stress factors
Journal 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]
Plant 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]
Plant 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 ...

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

Modeling Stomatal Conductance [PDF]
Plant Physiology, 2017 Recent advances have improved our ability to model stomatal conductance using process- or optimality-based models, and continuing research should focus on how stomata sense leaf turgor and on how to quantify the direct carbon costs of low leaf water potential.

Increasing leaf hydraulic conductance with transpiration rate minimizes the water potential drawdown from stem to leaf. [PDF]
, 2014 Leaf hydraulic conductance (k leaf) is a central element in the regulation of leaf water balance but the properties of k leaf remain uncertain. Here, the evidence for the following two models for k leaf in well-hydrated plants is evaluated: (i) k leaf is
