Non-photochemical fluorescence quenching is a mechanism that protects the photosynthetic apparatus of plants against photooxidative damage during exposure to excessive light intensities. Instead of converting light energy into charge separation in the reaction center, the photosynthetic apparatus dissipates the excitation energy into heat, a process that can be monitored as quenching of chlorophyll fluorescence. Non-photochemical quenching is connected to the acidification of the thylakoid lu...
