Impact of ozone on vegetation
Technical Report
·
OSTI ID:5011556
Visible injury on vegetation is one of the earliest and most obvious manifestations of ozone injury. However, ozone effects are not limited to visible injury; impacts range from reduced plant growth, decreased yield, changes in crop quality and alterations in susceptibility to abiotic and biotic stresses. Several approaches were used to estimate the ozone concentrations and exposure durations that induce foliar injury. Most of these studies used short-term exposures (less than 1 day) and measured visible injury as the response variables. An alternative approach for estimating ozone concentrations and exposure durations which induce foliar injury is the use of limiting value analysis. The limiting values were developed from a review of the literature and represent the lowest concentration and exposure duration reported to cause visible injury on various plant species. The analysis was based on more than 100 studies of agricultural crops and 18 studies of tree species.
