dc.description.abstractThe research of the effect of the biostimulant on the growth and development of plants of the ‘Robin’ lettuce variety was carried out in 2019–2020 in the department of closed artificial agroecosystems for crop production on the basis of the Federal State Budgetary Scientific Institution «Federal Scientific Agroengineering Center VIM», Moscow (VIM, Russia). Succinic acid was used at the stage of inoculation of seed and with constant drip irrigation of plants throughout the growing period. Lettuce plants were grown using a low-volume technology in a climatic chamber produced by VIM (Russia). According to the studies carried out, inoculation of seeds stimulates the development of plants at the initial stages, reducing the period from sowing to germination and increasing the rate of plant growth. As the lettuce plants grew, the leaf surface area increased from 221.0 to 1511.9 cm² with the addition of succinic acid to the hydroponic nutrient solution. The use of succinic acid under controlled growing conditions of ‘Robin’ lettuce plants allowed to increase the performance of the leaf apparatus in relation to the control. It was experimentally established that productivity directly depended on the value of photosynthetic potential and net productivity of photosynthesis, which is confirmed by a strong degree of dependence with a correlation coefficient of 0.98 and 0.77, respectively. Seed treatment and adding succinic acid to the hydroponic solution increases the accumulation of dry matter in lettuce plants. With this method of using succinic acid, significant differences in the accumulation of dry mass of plants were established. The share of the effect of the factor of inoculation of seeds with succinic acid was 17.5%, the addition of hydroponics to the nutrient solution was 50.1%. The use of succinic acid increases the accumulation of plant biomass, increases the total leaf surface area, and also contributes to an increase in the parameters of photosynthetic activity of the leaf apparatus of the ‘Robin’ lettuce plants under controlled conditions of the climatic chamber.eng
