Enhancement effect

property of higher plant photosynthesis, discovered by robert Emerson. The quantum yield of red light (less than 680nm) and far red light (700nm), when shone simultaneously on a plant, is greater than the sum of the yields of the light of the two wavelengths separately. This effect provides evidence for the cooperative interaction of two photosystems in photosynthesis.
