Применение биостимуляторов на основе различных соединений находит все более широкое применение в сельском хозяйстве в связи с необходимостью увеличения урожайности растений при нестабильных климатических условиях. Экзогенная обработка аминокислотами вегетирующих растений различных сельскохозяйственных культур позволила увеличить продуктивность, содержание биологически активных соединений, а также повысить их устойчивость при воздействии абиотических стрессов. Цикорий обыкновенный является перспективным видом лекарственного растительного сырья для получения фармацевтических субстанций с высоким содержанием цикориевой кислоты. Благодаря содержанию в листьях различных классов фенольных соединений, извлечения из надземной части цикория обладают иммуномодулирующим и гепатопротекторным действием.</p></sec><sec><title>Методика</title><p>Методика. В данной работе проведена оценка действия некорневой обработки однокомпонентными растворами фенилаланина, тирозина и триптофана в двух концентрациях (10 мг/л и 25 мг/л) на продуктивность растений и содержание фенольных соединений в листьях цикория обыкновенного.</p></sec><sec><title>Результаты</title><p>Результаты. Наиболее эффективны обработки аминокислотами в концентрации 10 мг/л. Применение триптофана позволило повысить продуктивность надземной части 29-57% в зависимости от концентрации (с 112 г до 144-176 г). Обработка всеми аминокислотами способствовала увеличению содержания фенольных соединений: фенилаланином – с 4,84% до 5,49%, тирозином – до 7,25%, триптофаном – до 6,23%. На массу корнеплодов обработка аминокислотами значимого влияния не оказала. Отмечено, что при благоприятных для развития растений метеорологических условиях применение аминокислот более эффективно, однако при неблагоприятных условиях значимого снижения показателей растений не происходит. Полученные результаты свидетельствуют о перспективности использования аминокислот как элемента технологии выращивания для повышения продуктивности растений и содержания в них биологически активных веществ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance.  Biostimulants based on different compounds is increasingly used in agriculture due to the need to increase plant yield under unstable climate conditions. Exogenous application with amino acids on various agricultural crops increased productivity, the content of biologically active compounds, and improved their resistance to abiotic stress. Common chicory is a promising medicinal plant for obtaining pharmaceutical substances with a high content of chicory acid. Due to the content of various classes of phenolic compounds in the leaves, extracts from the aboveground part of chicory have an immunomodulatory and hepatoprotective effect.</p></sec><sec><title>Methods</title><p>Methods. In this study, the effect of foliar application with single-component solutions of phenylalanine, tyrosine, and tryptophan at two concentrations (10 mg/L and 25 mg/L) on plant productivity and the content of phenolic compounds in the leaves of common chicory is assessed. Results. Treatment with amino acids at a concentration of 10 mg/L was most effective. The use of tryptophan increased the productivity of the aboveground part by 29-57% depending on concentration (from 112 g to 144-176 g). Treatment with all amino acids contributed to increase the phenolic compounds content: phenylalanine – from 4.84% to 5.49%, tyrosine – up to 7.25%, tryptophan – up to 6.23%. Amino acids application did not have a significant effect on the root weight. It was noted that under favorable climate conditions for plant development, the use of amino acids is more effective, but under unfavorable conditions, there is no significant decrease in plant indicators.</p></sec><sec><title>Results</title><p>Results.
