Direct Observation of Reversible and Irreversible Stomatal Responses of Attached Sunflower Leaves to SO(2)

Direct Observation of Reversible and Irreversible Stomatal Responses of Attached Sunflower Leaves to SO(2)

Plant Physiology 79(1): 153-158

Using a remote control light microscope system, it was shown that differences in the stomatal response in injured and uninjured regions could be distinguished in sunflower leaves after 1 h of exposure to 1.5 micro l SO2/l. The mean value of apertures for many stomata tended to decrease simultaneously in the injured and uninjured regions, but the rate of decrease was slower in the injured region because of a transient opening induced by water soaking in that region.
