Garcia et al. (1994) |
Seedlings rooted in the ground within transparent open-top enclosures maintained for 15 months at an atmospheric CO2 concentration of 402 ppm, after which short-term whole-tree net photosynthetic rates (one-hour averages) were measured at a number of different CO2 concentrations (changed at 1.5-hour intervals) ranging from ambient (360 ppm) to 3000 ppm
