- Аннотация: All types of vegetation, especially cereals, react to various changes, such as growth conditions, natural and anthropogenic factors. These first of all are reflected in the amount of phytomass, its fractional composition and, respectively, in its spectral signature. Spectral characteristics (spectral reflectance) of cereals allow to estimate an actual condition of crops on the basis of data processing of remotely sensed data and select the best parameters for plant cultivation. To reduce the number of variables influencing spectral characteristics of crops, we have conducted an experiment on influence of lighting conditions on growth of Hordeum Vulgare (barley). Measurements were made with ASD FieldSpec3 Hi-Res hyperspectroradiometer, intended for measurement of spectral radiance and reflectance. Barley was grown from seeds in bowls with identical nutrient solution during 10 days in uniform conditions of humidity, air temperature and convection. Three types of lighting were used: luminescent white, LED red and LED blue. In total more than 200 samples were measured. The most significant differences in reflectance were observed in the range of 750-1300 nm, which correlated well with phytomass of respective samples. There were also small differences in the range of 500-700 nm with samples grown under red light absorbing more radiation, than those grown under blue light. These data can be used in the future for monitoring condition of agricultural crops with remotely sensed data. The studies were conducted with the support of Russian Foundation for Basic Research (project 13-05-12061).
