| Two poplar clones, I-214 (Populus euramericana) and Peace (P. Koreana × P. trichocarpa), were grown for 21 days in growth chambers at different CO₂concentrations (350, 700 and 2,000 μL·L-1). I-214 has stomata responding to environmental conditions in normal ways and Peace has unresponsive stomata to environmental factors including light, ABA, water stress and CO₂. In both plants, elevated CO₂ stmulated the growth of plant parts, especially leaf dry weight. And a CO₂ enrichment of 700 μL·L-1 CO₂ caused increment of net assimilation rate (NAR). The growth responses of these plants to CO₂ enrichment were different especially at high CO₂ condition (2,000 μL·L-1 CO₂). The total dry weight in Peace increased up to 2,000 μL·L-1 CO₂ but not in I-214. A CO₂ enrichment of 2,000 2,000 μL·L-1 CO₂ had little effect on NAR of I-214 but enhanced NAR of Peace. Although it is uncertain whether the different responses to CO₂ enrichment between I-214 and Peace resulted from the different properties of stomatal responses to long-term CO₂ treatment, the decrease in NAR is probably due in part to CO₂-induced stomatal closure in I-214 but not in Peace. |
