Scasonal Dependence of the Spectral Brightness of Agricultural Crops on Plant Chlorophyll Content and Physiological Parameters

摘要

The paper analyses the results of multi-year studies of the state of agricultural crops based on plant reflectance during the growth period. A universal methodology for determining the physiological state, and plant phytopigment content from the value of the chlorophyll potential S (t) in the region of the red absorption band λ = 680 nm, which can b determined from the SBC values, is presented.
