Table 2.
The different environmental (CO2 concentration, air temperature), physiological (Vcmax and Jmax), and plant structural and developmental characteristics (leaf size, growth stage and leaf senescence) between the elevated CO2 and normal CO2 conditions.
| Factor | Ambient [CO2] | Elevated [CO2] |
|---|---|---|
| CO2 concentration (ppm) | 370 | 550 |
| Air temperature (°C) | T | T+1.5 |
| V cmax and Jmax | (+) | Higher in early stages and lower in later stages (+) |
| Leaf size (area of single leaf) | S (+) | 1.1–1.9 × S (+) |
| Growth stages | (+) | Earlier than ambient (+) |
| Leaf senescence | (+) | Earlier than ambient (+) |
