| Abstract: | Abstract. The effect of chlorophyll fluoresence on the spectral light gradients within a model green leaf was examined under different light qualities (day-light, sunset, canopy) and different quantum efficiencies. Light fluxes within the leaf tissue are nearly doubled in the emission domain of fluorescence but the effect on the phytochrome photoequilibrium is very small. |
