Method | The atmospheric CO2 partial pressure is increased by 20 Pa above ambient (˜56 Pa) within a 30-m-diameter experimental plot by using a system of vertical pipes (with regularly spaced exit ports along the length) connected to a circular plenum supplied with CO2 gas by a highly regulated computer-based control system. Nearby control sites of equivalent design and plant composition are at ambient atmospheric CO2 levels. |
Comments | Mitochondrial sizes in low and high CO2 treatments are statistically equivalent, as reported in the text. Relative counts of mitochondria per unit cell area represent differences in mitochondrial area. Elevated/ ambient ratio=1.7 |
