Formulae for coefficients of the “energy”-dependent quenching (qE), the state-transition quenching (qT) and the photo/inhibitory quenching (qI) of Chl a fluorescence were found on the basis of three assumptions: (i) the dark relaxation kinetics of qN, as well as of all its components, is of an exponential nature, (ii) the superposition principle is valid for individual Chl a fluorescence quenching processes, and (iii) the same reference fluorescence level (Fv) is used to define both qN and its components. All definitions as well as the algorithms for analytical recognition of the qN components are theoretically clarified and experimentally tested.
