Response of epidermal diffusive conductance to simultaneous changes in leaf water potential and photon flux density was studied in primary bean leaves. Values of epidermal conductance corresponding to every photon flux density decreased with decreasing leaf water potential below - 6.9 x 105Pa; slight deorease was followed by a rapid one at water potential ranging from - 8.0 to -10.5 x 105 Pa. In the leaves with water potential lower than -10.5 x 105 Pa neither the saturated photon flux density (1200 [xeinstein m-2s-1) induced photoactive stomatal opening.
Negative influence of one factor could be partially compensated by positive influence of the other. These results were in good agreement with the considered mechanism of action of leaf water potential and photon flux density on epidermal conductance.
