Synchronized microsporocytes and microspores of larch have been introduced as an excellent model system for the examination of the cell cycle dependence of biophoton emission (PE) and delayed luminescence (IPE). In agreement with the predictions of the model of Nagl and Popp for differentiation it could be experimentally confirmed that there exist: 1) sensitive dependence of PE and IPE on the cell cycle, 2) correlations to conformational states of DNA which are linked to DNase activity and 3) a hyperbolic decay of IPE. The electromagnetic model of differentiation predicts oscillations of IPE that should depend on the wavelength of the exciting light and the cell cycle phase. In the established larch model system evidence was obtained for the first time of these oscillations which showed a dependence on both wavelength of the inducing light and the stage of the cell cycle.
