✦ Synopsis

This paper highlights the stomatal dimensions and pressure relationships which might be genetically or environmentally altered to improve a plant's water-use efficiency. A simplified mathematical model of the guard cell has been shown to be consistent with experimental observations, and based upon this model a parametric analysis has been carried out. The model presented herein has revealed that the following cellular characteristics affect stomatal response to water stress: (a) the osmotic potential of the guard cell;

(b) the osmotic potential of the epidermal cells; (c) the semi-circumference of the pore; (d) the wall thickness of the guard cell; (e) the modulus of elasticity of the cell wall material; and (f) the size of the guard cell itself.
