Растения используют свет не только как источник энергии для фотосинтеза, но и как важный регулятор их роста и развития. Характеристики света, такие как интенсивность, спектральный состав, продолжительность освещения, а также особенности светового потока, играют ключевую роль в физиологических процессах растений. Поэтому важно отработать режимы освещения необходимые для роста различных видов растений, чтобы управлять их метаболическими процессами.Материал и методика. В работе в качестве объектов исследования одновременно изучались привитая рассада огурца Кабеири F1 на подвое Лагенария и сеянцы картофеля, полученные из ботанических семян, сортов отечественной и зарубежной селекции: Гулливер, Удача, Винета, Беллороза, Риккарда, Индиго. Выращивание двух культур проводилось в условиях светокультуры с длительностью дня 12,14 и 16ч. Для освещения растений использовали светодиодные лампы с синим (440-445нм) и красным спектрами (660-665нм) в следующих соотношениях: 60/40, 50/50 и 40/60. Исследования проводились в трехкратной повторности по 20 учетных растений. Технология выращивания растений в защищенном грунте общепринятая для Волгоградского региона.Результаты. При оценке влияния биколорного досвечивания привитого огурца наиболее подходящим оказалось соотношение R60B40, оно способствовало активному развитию вегетативной части, а увеличение фотопериода до 14-16 часов предотвращало вытяжение междоузлий на 2,0 см и подсемядольного колена у подвойной части. Превалирование синего спектра негативно сказывалось на привитой рассаде: снижение ростовой активности, сокращение длины междоузлий, а при длине дня в 16 ч – вершкование точки роста. При оценке развития вегетативной части рассады картофеля, полученной из ботанических семян, можно отметить похожую реакцию надземной части как у привитого огурца Кабеири F1. Однако при оценке урожайности мини-клубней, именно преобладание синего спектра повышало процент урожайности до 26,1% при фотопериоде в 16 ч. </p></abstract><trans-abstract xml:lang="en"><p>Relevance. Plants use light not only as an energy source for photosynthesis, but also as an important regulator of their growth and development. The characteristics of light, such as intensity, spectral composition, duration of illumination, as well as the characteristics of the luminous flux, play a key role in the physiological processes of plants. Therefore, it is important to work out the lighting modes necessary for the growth of various plant species in order to control their metabolic processes.Material and methodology. In the work, grafted seedlings of Kabeiri F1 cucumber on the rootstock of a Lagenarium and potato seedlings obtained from botanical seeds of domestic and foreign varieties were simultaneously studied as objects of research: Gulliver, Luck, Vineta, Bellorosa, Riccarda, Indigo. The two crops were grown under light culture conditions with a day duration of 12.14 and 16 hours. LED lamps with blue (440-445 nm) and red (660-665 nm) spectra were used to illuminate the plants in the following ratios: 60/40, 50/50 and 40/60. The studies were carried out in three repetitions of 20 registered plants. The technology of growing plants in protected soil is generally accepted for the Volgograd region.Results. When assessing the effect of bicolor illumination of a grafted cucumber, the R60B40 ratio turned out to be the most suitable, it contributed to the active development of the vegetative part, and an increase in the photoperiod to 14-16 hours prevented the extension of the internodes by 2.0 cm and the subsameral knee at the rootstock. The prevalence of the blue spectrum had a negative effect on the grafted seedlings: a decrease in growth activity, a reduction in the length of the internodes, and with a day length of 16 hours, the tip of the growth point. When assessing the development of the vegetative part of potato seedlings obtained from botanical seeds, it is possible to note a similar reaction of the tops as in the grafted Kabeiri F1 cucumber. However, when assessing the yield of mini tubers, it was the predominance of the blue spectrum that increased the yield percentage to 26.1% with a photoperiod of 16 hours.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>картофель</kwd><kwd>ботанические семена</kwd><kwd>огурец</kwd><kwd>рассада</kwd><kwd>прививка</kwd><kwd>досвечивание</kwd><kwd>светодиоды</kwd><kwd>защищенный грунт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>potato</kwd><kwd>botanical seeds</kwd><kwd>cucumber</kwd><kwd>seedlings</kwd><kwd>grafting</kwd><kwd>additional illumination</kwd><kwd>LEDs</kwd><kwd>protected soil</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bourget C.M.
