However, if carbon balance is expressed per unit leaf mass, or per unit soluble leaf
protein, a different picture appears (Figs 2b and 2c). In both cases, leaves acclimated
to low irradiance do better at low irradiance than those acclimated to other irradiances;
leaves acclimated to intermediate irradiance do better than others at intermediate
irradiance; and leaves acclimated to high irradiance do better than others at high
irradiance.
