Factors Influencing Plant Responses
The occurrence and magnitude of vegetation effects are dependent on the concentration, frequency and duration of exposure, time between exposures, the magnitude of the concentration changes, diurnal timing of exposures, their sequence and pattern, and ozone flux into the plant as it is influenced by canopy characteristics and the leaf boundary layer (Jacobsen 1982). Most ozone response studies have considered only the concentration and duration of exposures, while the other parameters that also influence pollutant response have received only cursory study.
