SEASONAL CHANGES IN SPECTRAL BRIGHTNESS OF AGRICULTURAL CROPS AS A FUNCTION OF CHLOROPHYLL CONTENT AND PLANT CONDITIONS

Abstract

The results of multiyear research on the condition of agricultural crops are analyzed on the basis of data on the reflectance of plants during their growing season. A universal method is proposed for assessing the physiological state and content of plant pigments on the basis of the chlorophyll potential S(t) in the red absorption band λ = 680 nm, as determined from spectral brightness coefficients.
