[Theoretical analysis of inductive effects in higher plant photosynthesis].
The proposed mathematical model of the light stages of photosynthesis in higher plants takes into account the regulatory process of excitation energy redistribution between photosystems depending on the redox state of electron carriers. Nonmonotonic changes in the intensity of pigment fluorescence upon switching on the excitation light (delayed fluorescence induction) are described. The time required for fluorescence to reach its peak intensity and the degree of fluorescence quenching depending on light intensity are analyzed. Th kinetics of light-induced changes in EPR I signal upon switching from the far-red to white light is simulated.
