Diel patterns of sucrose, glucose and fructose (mmol m⁻²) for young fully expanded leaves of Aechmea ‘Maya’ at ambient (380 µmol mol⁻¹) and elevated (700 µmol mol⁻¹) CO₂. The four different phases of CAM are indicated and the grey line shows a phase shift caused by CO₂ elevation. Data are means ± s.e. (n = 10 plants).
