Conductance for water vapor, assimilation of CO(2), and intercellular CO(2) concentration of leaves of five species were determined at various irradiances and ambient CO(2) concentrations. Conductance and assimilation were then plotted as functions of irradiance and intercellular CO(2) concentration. The slopes of these curves allowed us to estimate infinitesimal changes in conductance (and assimilation) that occurred when irradiance changed and intercellular CO(2) concentration was constant… 

Effect of irradiance and vapour pressure deficit On stomatal response to CO2 enrichment of four tree species

The stomatal response of seedlings grown in 360 or 720 μmol mol -1 to irradiance and leaf-to-air vapour pressure deficit (VPD) at both 360 and 720 μmol mol - 1 CO 2 was measured to determine how

It is concluded that stomata respond to intercellular CO(2) concentration and are insensitive to the CO( 2) concentration at the surface of the leaf and in the stomatal pore.

Evidence for Involvement of Photosynthetic Processes in the Stomatal Response to CO21

Results suggest that part of the stomatal response to ci involves the balance between photosynthetic electron transport and carbon reduction either in the mesophyll or in guard cell chloroplasts.

Effect of Light Quality on Stomatal Opening in Leaves of Xanthium strumarium L.

Determination of flux response curves on leaves in the normal position or in the inverted position led to the conclusion that the photoreceptors for blue as well as for red light are located on or near the surfaces of the leaves; presumably they are in the guard cells themselves.

Stomatal acclimation to dynamic light: implications for photosynthesis and water use efficiency

The findings in this study illustrate the impact of growing plants in dynamic light regimes, similar to those experienced by plants in the natural environment, on the physiology and performance of model species Populus nigra and Arabidopsis thaliana and emphasizes that growing plants under laboratory conditions and square-wave illumination does not accurately represent plant acclimation and development under a natural environment.

Distinct light responses of the adaxial and abaxial stomata in intact leaves of Helianthus annuus L.

Using a laboratory-constructed system that can measure the gas exchange rates of two leaf surfaces separately, the light responses of the adaxial and abaxial stomata in intact leaves of sunflower were investigated, highlighting a strong dependence of stomatal opening on mesophyll photosynthesis.

Photosynthesis and Water Use Efficiency 1(C)

Manipulating guard cell transport and metabolism is just as, if not more likely to yield useful benefits as manipulations of their physical and anatomical characteristics as achieving these benefits should be greatly facilitated by quantitative systems analysis.

Stomatal sensitivity to carbon dioxide and humidity: a comparison of two c(3) and two c(4) grass species.

The sensitivity of stomatal conductance to changes of CO(2) concentration and leaf-air vapor pressure difference (VPD) was compared between two C(3) and two C(4) grass species. There was no evidence

Stomatal conductance and transpiration in shoots of Scots pine after 4-year exposure to elevated CO2 and temperature

Long-term elevation of CO2 led to a significant decline in the absolute value of gs at almost all levels of Qp, Dv, Ci, and Tl, while the effect of the combination of elevated CO2 and temperature did not appear as a mean of the effects of the two single factors, while there was an interaction between the two factors.

STOMATAL RESPONSES TO ILLUMINATION

It is concluded that changes in carbon dioxide concentration set in motion reactions affecting guard cell turgor relations, and it is confirmed that effects of such factors can be reversed experimentally by flushing the leaf with air of an appropriate carbon dioxide content.
