✦ Synopsis

Complete room temperature fluorescence emission spectra of green and etiolated leaves (Raphanus saHvus L., cv. Saxa Treib, Hordeum vulgate L., cv. Villa) are continuously recorded up to 4 rain after onset of excitation. In green leaves two emission bands appear, whereas in etiolated leaves only one band is observed. In both cases the emission intensity increases with time, the high-energy band of green leaves decreasing more rapidly than the low-energy band. This phenomenon can be interpreted in terms of energy transfer. During the observation time of the fluorescence induction kinetic no shift of the emission peaks is found within the accuracy of the apparatus (-+ 2 nm).
