Abstract
The advantage of FLORA LED lighting in comparison with HPS lamps for cultivation of tall tomato varieties under production conditions is shown. Under LED illumination with well-balanced spectral composition, the main growth and physiological parameters of tomato juvenile plants (such as dry weight and accumulation of dry matter of vegetative organs, content of photosynthetic pigments, rate of oxygen release during photosynthesis, coefficient of photosynthetic efficiency, time of flowering onset) were superior to plants grown under HPS lamp illumination. It is assumed that increased photosynthetic activity, as well as more intensive growth and development processes provided a higher adaptive potential and survival during transplantation, early fruiting. and higher yields to plants grown under LED lighting.
