TLDR
Stomata of Zea mays L. respond to changes in hydrostatic pressure in the water supply of the leaves almost instantaneously and in all leaf parts simultaneously, therefore, the leaf is a hydraulic unit and their aperture is controlled by the water potential in theWater-conducting system.Abstract:
Stomata of Zea mays L respond to changes in hydrostatic pressure in the water supply of the leaves almost instantaneously and in all leaf parts simultaneously Therefore, the leaf is a hydraulic unit The stomata are part of it and their aperture is controlled by the water potential in the water-conducting system Stomatal aperture is not uniquely related to the relative water content of a leaf The relation depends also on the humidity in the air and is different for the upper and the lower epidermisread more

Ecophysiology of Photosynthesis
TL;DR: In a world of increasing atmospheric CO2, there is intensified interest in the ecophysiology of photosynthesis and more attention is being given to other aspects of carbon exchange and storage in natural ecosystems.

Stomatal Behaviour and Environment
TL;DR: The transient response of stomata to change in rate of evaporation may be a device which is designed to enhance the speed of the response to light.

Stomatal Responses, Water Loss and CO2 Assimilation Rates of Plants in Contrasting Environments
Ernst Detlef Schulze,A. E. Hall +1 more
TL;DR: The stomatal aperture appears to be controlled by complex mechanisms which operate to maintain a variable balance between allowing CO2 uptake to proceed, while restricting the loss of water vapor, and preventing leaf desiccation as mentioned in this paper.

The control of stomata by water balance.
TL;DR: It is argued that a metabolically mediated feedback response of stomatal guard cells to the water status in their immediate vicinity ('hydro-active local feedback') remains the best explanation for many well-known features of hydraulically relatedStomatal behaviour, such as transient 'wrong-way' responses and the equivalence of hydraulic supply and demand as stomatic effectors

TL;DR: Practical information on the hardware, methodology, and the hands on application of chlorophyll (Chl) a fluorescence technology is provided to scientists who have some experience with the application but are still in the process of discovering what it all means and how it can be used.

Pressure and Flow Relations in Vascular Bundles of the Tomato Plant
TL;DR: In the tomato plant water flows through primary xylem in accordance with Poiseuille's law, and pressure and flow relations are apparently not greatly altered when localized dysfunction occurs in the vessels of large bundles.

Salt transport in Valonia: inhibition of potassium uptake by small hydrostatic pressures.
TL;DR: This inhibition of salt uptake by a small hydrostatic pressure suggests that Valonia and other walled cells may regulate their turgor pressures by adjusting their rates of Salt uptake.
