NE176: Characterization and Mechanisms of Plant Responses to Ozone in the Northeastern U.S.
Statement of Issues and Justification
Tropospheric ozone resulting from man's activities is the major air pollutant effecting crops and native vegetation in the eastern US. A strong oxidant, ozone causes foliar injury, accelerates leaf senescence, and reduces growth and yield of many species. While the effects of ozone have been well documented, several aspects of its toxicity are poorly understood. A more complete understanding of plant responses to ozone in the Northeast would enable more effective development of ozone resistant varieties , as well as provide additional information for developing ambient air quality standards.
