A method for determination of the effects of air pollutants on the stomatal width



A method for determination of the effects of air pollutants on the stomatal width



Silva Fennica 15(4): 392-395



The method described is based on the idea that changes in the water content of a plant can be measured by measuring changes in the thickness of any part of the plant. A leaf kept in darkness changes its thickness to a sufficient degree for recording changes in transpiration from the rest of the plant. The rapidity of the changes suggests that they are reflecting stomatal movements. The method has been used for recording the effects of SO2.
