Abstract: | Stomatal responses of attached bean (Phaseolus vulgaris L.) leaves to changing spectral composition ("white" - WL., blue - BL, or red - RL radiation), air humidity (100 % or about
4 % RH), and water potential of the root medium (close to 0 or −1.2 MPa) were determined by air flow porometer. Opening of
stomata always increased under BL and decreased under RL. In response to decline in air humidity, leaf conductance showed
transient increase before it reached lowered steady state. BL enhanced and RL diminished this response.
