The temperature dependence of delayed luminescence of Hibiscus rosa sinensis leaves was studied in the temperature range from -25 degrees C to degrees C. Temperature dependence of the steady-state delayed luminescence intensity has two maxima, at -10 and at +35 degrees C. For the theoretical modeling, the mathematical model of plant photosynthesis developed earlier was used. The temperature dependence of the delayed fluorescence induction was obtained by introducing into the model the temperature dependences for 12 rate constants derived from the data on the effect of temperature on different stages of photosynthesis. The theoretical temperature dependence of the steady-state delayed luminescence was shown to have the same shape as the experimental one.
