Neither xylem collapse, cavitation or changing leaf conductance drive stomatal closure in wheat.
Plant, Cell and Environment, 2020Identifying the drivers of stomatal closure and leaf damage during stress in grasses is a critical prerequisite for understanding crop resilience. Here we investigated whether changes in stomatal conductance (gs ) during dehydration were associated with ...

Stomatal conductance and stomatal behavior in Populus clones and hybrids
Canadian Journal of Botany, 1988Responses of abaxial, adaxial, and total leaf conductance to incident photosynthetic photon flux density, solar irradiance, and changing leaf water potential, as well as diurnal and seasonal patterns of stomatal conductances, were examined under field conditions for six Populus clones. Clones belonged to the species P.

Planta, 1972
Measurements of transpiration, leaf water content, and flux of water in a cotton plant exhibiting sustained oscillations, in stomatal conductance are presented, and a model of the mechanism causing this behaviour is developed. The dynamic elements, of the model are capacitors-representing the change of water content with water potential in mesophyll ...

Stomatal conductance correlates with photosynthetic capacity
Nature, 1979Previous studies on the Physiology of stomata in higher plants suggest that stomata influence the rate of CO2 fixation in leaf mesophyll tissue. We believe that an equally important stomatal function has not been fully recognised; that stomatal aperture is determined by the capacity of the mesophyll tissue to fix carbon.

An Empirical Model of Stomatal Conductance
Australian Journal of Plant Physiology, 1984An empirical model of stomatal conductance is presented. The predictions of conductance correlate with experimental determinations of the responses to several kinds of short-term and long-term perturbations, including irradiance, temperature, CO2 and O2 partial pressures, and leaf age and nitrogen nutrition.

Comparing optimal and empirical stomatal conductance models for application in Earth system models
Global Change Biology, 2018Earth system models (ESMs) rely on the calculation of canopy conductance in land surface models (LSMs) to quantify the partitioning of land surface energy, water, and CO2 fluxes.

Patchy stomatal conductance: emergent collective behaviour of stomata
Trends in Plant Science, 2000Until recently, most scientists have tacitly assumed that individual stomata respond independently and similarly to stimuli, showing minor random variation in aperture and behaviour. This implies that stomatal behaviour should not depend on the scale of observation. However, it is now clear that these assumptions are often incorrect.

Stomatal and surface conductance of tropical rainforest
Agricultural and Forest Meteorology, 1991Abstract Although the absolute values of stomatal conductance of tropical rainforest vary greatly, there is some similarity in the response to humidity deficit and radiation. Stomatal conductance decreases downward through the canopy of Amazonian rainforest.

Modification of Stomatal Conductance by Sulphur Dioxide
Journal of Experimental Botany, 1989The mechanism of S02-induced changes in stomatal conductance (g) of alder was examined to determine if S02 affects guard cell function directly or indirectly through the S02-induced changes in photosynthesis. During experimental fumigations at S02 concentrations of 3-3 /?mol m"3 (0 08 /J 1 " stomatal closure preceded declines in net photosynthetic rate
