The gas exchange of leaves of the Ilex rotunda trees planted at thirteen sites in the city of Fukuoka, Japan, with various sun light conditions and air pollutant concentrations was studied. The highest maximum photosynthetic rate and the stomatal conductance of single leaves were measured under controlled conditions and
Important physiological processes, photosynthesis, respiration, carbon allocation and stomatal function are known to be affected by air pollutants. A wide range in sensitivity of photosynthesis both within and between species is evident from the literature for the pollutants sulphur dioxide, ozone, nitrogen oxide and hydrogen
When plants are exposed to the environmental pollution above the normal physiologically acceptable range, photosynthesis gets inactivated. Since, the plants leaf samples used for this experiment were constantly exposed to air pollutants (polluted area- industrial area, automobile area & less polluted area – jungle, they
