Abstract

Ozone-sensitive (S156) and -tolerant (R123 and R331) genotypes of snap bean (Phaseolus vulgaris L.) were tested as a plant bioindicator system for detecting O ₃ effects at current and projected future levels of tropospheric O ₃ and atmospheric CO ₂ under field conditions. Plants were treated with ambient air, 1.4× ambient O ₃ and 550 ppm CO ₂ separately and in combination using Free Air Concentration Enrichment technology. Under ambient O ₃ concentrations pod yields were not significantly different among genotypes. Elevated O ₃ reduced pod yield for S156 (63%) but did not significantly affect yields for R123 and R331. Elevated CO ₂ at 550 ppm alone did not have a significant impact on yield for any genotype. Amelioration of the O ₃ effect occurred in the O ₃ + CO ₂ treatment. Ratios of sensitive to tolerant genotype pod yields were identified as a useful measurement for assessing O ₃ impacts with potential applications in diverse settings including agricultural fields.
