Разработана методика, позволяющая включать в них до 40 мас. % регулятора роста растений – транс-коричную кислоту (ТКК). Установлено, что полное высвобождение ТКК в среде культивирования клеток (Мурасиге–Скуга) протекает за 2,5 ч. Полученные частицы пектината кальция не влияют на ростовые процессы клеток суспензионной культуры и могут быть использованы в качестве нейтральных носителей регуляторов роста.</p></abstract><trans-abstract xml:lang="en"><p>Hydrogel negatively charged (–13.5 ± 5.0 mV) calcium pectinate nano- and submicroparticles (50–150 nm) were obtained. A technique for entrapment of a plant growth regulator (trans-cinnamic acid) in the particles up to 40 wt. % has been developed. It has been established that the complete release of trans-cinnamic acid in the Murashige–Skoog medium takes 2.5 hours. The obtained particles of calcium pectinate do not affect the growth processes of cells in suspension culture and can be used as neutral carriers for growth regulators.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пектин</kwd><kwd>гидрогелевые наночастицы</kwd><kwd>транс-коричная кислота</kwd><kwd>суспензионные культуры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pectin</kwd><kwd>hydrogel nanoparticles</kwd><kwd>trans-cinnamic acid</kwd><kwd>suspension cultures</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">Hydrogel Nanoparticles of Chitosan–Folic-Acid Conjugate with Imatinib Methanesulfonate / M.
