The paper describes the results of in situ and numerical experiments connected with the investigation of the space gradient of chlorophyll fluorescence in the volume of a plant leaf. We demonstrated for the first time that the continuum of UV radiation of exciplex lamps can serve as an effective source inducing the process of spontaneous fluorescence of a leaf photosystem. The estimations made, using the Monte Carlo method, confirm that the basic reason for transformation of emission spectrum of induced fluorescence in the leaf volume transmission are the reabsorption processes.
