The non-destructive monitoring systems use for plant stress conditions detecting and evaluating can improve the performed research and working procedures quality significantly. Such systems concepts are based on obtaining of the leaves’ reflective characteristics, the spectrum, and the chlorophyll fluorescence induction. By several methods combining for plant stress states detection within a single device, for different crops, it is possible to increase the evaluation accuracy and extend the device functionality. The laboratory prototype of the device for plants’ stress states determining was developed and tested on plants of basil garden variety. It was shown that the impact of the stress factor in the form of the UV-C radiation was expressed in the shape change of the fluorescence spectrum, namely, in the fluorescence intensity fall in the long-wave part of the spectrum. Also it was shown that the reflectivity decreased in the green and far red regions of the spectrum. At the spectra registration in the red and IR sections of the spectrum, some noises and interference distortions were detected, which can be filtered out by ways of demodulation and calculation of the trigonometric component of the interference distortion functions.
