Hydraulic constraints to stomatal conductance in flooded trees. [PDF]
OecologiaAbstract Stomatal closure is a pervasive response among trees exposed to flooded soil. We tested whether this response is caused by reduced hydraulic conductance in the soil-to-leaf hydraulic continuum (k total), and particularly by reduced root hydraulic conductance (k root), which has been widely hypothesized.

Stomatal conductance limited the CO2 response of grassland in the last century [PDF]
BMC Biology, 2021 Background The anthropogenic increase of atmospheric CO2 concentration (c a) is impacting carbon (C), water, and nitrogen (N) cycles in grassland and other terrestrial biomes.

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 ...

Smaller, faster stomata: scaling of stomatal size, rate of response, and stomatal conductance [PDF]
Journal of Experimental Botany, 2013 Maximum and minimum stomatal conductance, as well as stomatal size and rate of response, are known to vary widely across plant species, but the functional relationship between these static and dynamic stomatal properties is unknown. The objective of this study was to test three hypotheses: (i) operating stomatal conductance under standard conditions (g

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 ...

Geophysical Research Letters, 2022 The spatio‐temporal variation of stomatal conductance directly regulates photosynthesis, water partitioning, and biosphere‐atmosphere interactions. While many studies have focused on stomatal response to stresses, the spatial variation of unstressed ...

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.

Stomatal conductance increases with rising temperature [PDF]
Plant Signaling & Behavior, 2017 Stomatal conductance directly modifies plant water relations and photosynthesis. Many environmental factors affecting the stomatal conductance have been intensively studied but temperature has been largely neglected, even though it is one of the fastest changing environmental variables and it is rising due to climate change.

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.
