Abstract
Absorption spectra of pigments derived from the plants that were illuminated by light with different spectral composition during their growth are presented. The role of the spectrum of LED lighting in the life of plants has been estimated, and its influence on pigment absorption has been noted. It has been recommended to use a full range of lighting in the range of 400–700 nm with the domination of the red component when growing oats in protected ground. It has been found that the recording of absorption spectra of pigments allows the monitoring of the influence of lighting on the processes of plant growth and development. It has been assumed that the use of sources with a controlled spectrum in a greenhouse will allow directed influence on the nature of biochemical reactions occurring in plants during their development: photosynthesis and photomorphogenesis.
