Keywords: stomata movement dynamics, water deficit, Phaseolus vulgaris
Abstract: Abstract. The increase in epidermal conductance of primary bean leaves started within 10 rain after irradiation by 1200 ~mol m -2 s -1 of darkened plants. The rate of stomatal opening increased to a maximum and then decreased till a steady-state value of epidermal conductance was reached. Stomata on the abaxial epidermis always started to open sooner and opened faster than stomata on adaxial epidermis. Both water stress and ageing of leaves delayed the beginning of opening and decreased the opening rate as well as the steady-state values of epidermal conductanee.
