Spectral reflectance curves (SRCs) of ethanol extracts of leaf pigments concentrated on filter paper were analyzed. The areas of the spectrum that were the most subject to change in the process of pathogenesis were identified. A change in the slope of the SRC was noted in the area connecting the poi...
