Investigation of the processes connected with the transfer of an electron in the chlorolayers of higher plants by the method of thermoluminescence

Five thermoluninescence peaks in the chlorolayers of higher plants were detected with temperatures of the maxima (T_$M$) of -l65°C, -10°C, +25°C and +55°C. The spectral characteristics of the first three peaks were obtained. The dependence of the intensity of the thermoluminescence of the peaks with (T_$M$) equal to -10°C and +25°C on the temperature of the radiation was established. The effect of different additions (diuron, DCPIP, mixtures of DCPIP with ascorbate and mixtures of ferricyanide and ferrocyanide) which act on the chain of the electron transfer between two photosystems, on the characteristics of the thermoluminescence of the peaks (T_$M$) equal to -10°C and + 25°C are investigated. The results of the experiments are interpreted within the framework of the hypothesis which explains the thermoluminescence as due to the reverse transfer of electrons from restored carriers in the chain of electron transport between two photosystems.
