Measurement of Chlorophyll Fluorescence in Lichens

摘要: Chlorophyll fluorescence (CF) is the absorption of blue or red photons (= excitation) by chlorophyll molecules and emission far (the energy difference lost as heat). In contrast to chloroform solutions fluorescent dyes, from active photosynthetic systems does not remain constant, but changes in a complicated way after constant excitation light switched on. These variable fluorescence) are due onset reactions that consume absorbed quanta. Accordingly, several derived parameters (see below) provide diagnostic information about state apparatus.
