Abstract:

Laser fluorescence method of plant state detection is considered. Laboratory setup is described and analysis of plant fluorescence spectra excited at a wavelength of 532 nm are presented. It is shown that the measurement small series average of the fluorescence intensity ratio R at wavelengths of 685 and 740 nm is marked by high stability for different samples of a plant. Sum of confidential intervals of ratio R (for confidential probability 95%) in most cases is no more than difference of mean values of the ratio R for normal and stress states caused by various reasons.

Keywords:

laser fluorescence method, vegetation monitoring, fluorescence spectra, stability
