Laser fluorescence method for detection of plant stress is considered. Processing results of experimental fluorescence spectra of plants in normal and different stress situations are given for a fluorescence excitation wavelength of 532 nm. Сomparative analysis of different variants of spectral bands of plants fluorescence radiation recording is carried out. It is shown that for vegetation monitoring problem spectral bands with central wavelengths 685 и 740 nm are most efficient bands in the context of stress situations detection reliability.
