Отмечена видовая специфичность ответной реакции проростков изучаемых культур на внесение ЭБЛ в смеси с ингибирующей рост дозой глифосата. Данная специфичность выражается в ослаблении ингибирующего эффекта глифосата на содержание флавоноидов в тканях льна-долгунца и в отсутствии изменения уровня флавоноидов в корнях и надземной части проростков ярового ячменя.</p></abstract><trans-abstract xml:lang="en"><p>The effect of epibrassinolide (EBL) on the content of flavonoids in seedlings of fiber flax (Linum usitatissimum L.) and spring barley (Hordeum vulgare L.) under chemical stress caused by N-phosphonomethylglycine (glyphosate) was studied. The species specificity of the response of the seedlings to the introduction of EBL in a mixture with an inhibitory dose of glyphosate was noted. This specificity is expressed in the suppression of the inhibitory effect of glyphosate on the flavonoids' content in the tissues of fiber flax and the absence of changes in the level of the content of flavonoids in the roots and aerial part of spring barley seedlings.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>флавоноиды</kwd><kwd>стресс</kwd><kwd>глифосат</kwd><kwd>N-фосфонометилглицин</kwd><kwd>брассиностероиды</kwd><kwd>эпибрассинолид</kwd><kwd>ингибирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flavonoids</kwd><kwd>stress</kwd><kwd>glyphosate</kwd><kwd>N-phosphonomethylglycine</kwd><kwd>brassinosteroids</kwd><kwd>epibrassinolide</kwd><kwd>inhibition</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">Макаренко, О.
