При светодиодном освещении хорошо сбалансированного спектрального состава растения томата уже в стадии вегетативного роста (рассады) по основным физиологическим показателям (сухая масса и накопление сухого вещества вегетативных органов, содержание фотосинтетических пигментов, скорость выделения кислорода при фотосинтезе, коэффициент фотосинтетической эффективности) превосходили растения, выращенные при освещении лампами ДНаТ. Предполагается, что повышенная фотосинтетическая активность и интенсивные процессы роста и развития обеспечили растениям, выращенным при LED-освещении, более высокий адаптивный потенциал и приживаемость при пересадке, раннее плодоношение и повышение урожайности.</p></abstract><trans-abstract xml:lang="en"><p>   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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>LED-освещение</kwd><kwd>спектральный состав</kwd><kwd>Lycopersicon esculentum Mill</kwd></kwd-group><kwd-group xml:lang="en"><kwd>LED lighting</kwd><kwd>spectral composition</kwd><kwd>Lycopersicon esculentum Mill</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках проекта «Осуществить сравнительный мониторинг физиолого-биохимических процессов и продуктивности растений томата и культур для салатных линий при экспериментальной светодиодной и традиционной досветках в условиях опытно-производственного участка, разработать временные регламенты досветки томата и зеленных культур» (2016–2018 гг.), финансируемого из инновационного фонда Мингорисполкома</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the project “To carry out a comparative monitoring of physiological and biochemical processes and productivity of tomato plants and crops for lettuce lines under experimental LED and traditional lighting in the conditions of a pilot production site, to develop temporary regulations for the lighting of tomato and green crops” (2016–2018) and financed by the innovation fund of the Minsk City Executive Committee</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Plasticity of photosynthetic processes and the accumulation of secondary metabolites in plants in response to monochromatic light environments: A review / M.
