Efficiency of light reaction is commonly measured using chlorophyll fluorescence techniques or oxygen evolution and denoted photosynthetic ‘quantum efficiency’ (also ? F/ F m ' using fluorescence terminology), which quantifies the conversion of absorbed photons to transported electrons. Quantum efficiency of photosynthesis varies between 0.83 and close to zero at leaves of dark-adapted higher plants and depends primarily on light intensity (Björkman & Demmig 1987 Rascher, Liebig & Lüttge 2000).
