Stomatal conductance correlates with photosynthetic capacity

Nature, 1979
Previous 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, 1984
An 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.

Patchy stomatal conductance: emergent collective behaviour of stomata

Trends in Plant Science, 2000
Until 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, 1991
Abstract 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, 1989
The 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

Water Use Efficiency and Stomatal Conductance

2016
The great influence of increased [CO2] on stomatal conductance is documented and presented in an overview table. It is also shown that in a dense stand of deciduous tree saplings conductance is clearly reduced at elevated [CO2].

Stomatal conductance modeling through model ED2.2

Models that predict the stomatal conductance process (gs) for a given set of environmental conditions are important, as this process is the main mechanism that controls the gas exchange of terrestrial plants absorbing atmospheric CO2. This work presents the results of a simulation to observe the gs process as a function of soil water availability (WAP)
