Comments C. claviformis shows an extremly high efficiency due to its light-fixation curve not saturating until very high irradiation levels (around full sunlight). These (rates of photosynthesis, BNID 107709,107710) correspond to an efficiency of energy conversion (photosynthetically active energy received divided by energy converted) of 8.5 and 3 percent, respectively, for Camissonia and sugar beet. Efficiencies based on the total solar spectrum would be approximately one-half of those given.
