Current projections indicate steady increases in both tropospheric ozone and carbon dioxide well into the next century with concurrent increases in plant stress. Because information about effects of these interacting stresses on forest trees is limited, we have conducted ozone and carbon dioxide experiments using ozone-tolerant and ozone-sensitive trembling aspen clones. Aspen plants were grown either in pots or in the ground in open-top chambers. Plants in the square-wave study were exposed for a single growing season to charcoal-filtered air or to CFplus elevated carbon dioxide, ozone, .
