Надслабке світіння рослин

Plant tissues emit extremely faint photons, detectable only with sensitive instruments and invisible to the human eye. Much of this ultraweak emission is associated with chemical reactions during metabolism and oxidative stress; photosynthesis can contribute to these processes. It is not a bright glow intentionally used by plants for photosynthesis, and it should not be confused with chlorophyll fluorescence or delayed luminescence after illumination.
