Photosynthetic production and wavelength-dependent energy migration

If the migration of the excitation energy depends on the wavelength of the exciting light then this can be expected to influence also photosynthetic production in monochromatic light. In the present investigations we started from this assumption. Tomato and paprika seedlings were used in the experiments. Analysis of the results obtained the two plants does not give a univocal answer to the question of whether the wavelength-dependent energy migration plays an important role in the dry-weight increase of the plants. It is beyond doubt, however, that the chlorophyll content and the dry matter increase are affected by the wavelength of the light to a considerable degree.
