Earlier at the biophysics department, the experimental data on the oscillations of delayed luminescence have been described with the help of a mathematical model. Here we studied the influence of the model parameters on the characteristics of the oscillatory regime. The frequencies and damping factors of the oscillations at different parameter values were calculated using the Lyapunov analysis. It was shown that, in addition to oscillations observed experimentally, other, rapidly damping oscillations may exist. The dependence of the CO2 assimilation rate on the model parameters was studied. It was shown that the intensity of the light absorbed by photosystems I and II may differently affect the assimilation of CO2.
