Abstract

This study was conducted at the Aspen Free-Air Carbon Dioxide Enrichment (FACE) experimental site, Rhinelander, WI, (USA). Since 1998, 12 experimental rings planted in 1997 underwent four different treatments: control; elevated CO₂ (560 ppm); elevated O₃ (1.5X ambient) and elevated CO₂ (560 ppm) + O₃ (1.5X ambient). In our study, foliage samples of Populus tremuloides Michx. were collected in the summer of 2006, 2007 and 2008 from each of three clones; namely, 216 (O₃ tolerant), 271 (intermediately O₃ tolerant) and 259 (O₃ sensitive) growing within the aspen only sector of each ring.
