Effect of phytohormones cytokinins on the growth and development of plants / Sydorchuk Pavlo Serhiyovych, Voronkova Yuliia S. // Тиждень студентської науки – 2023 : матеріали 78-ої студентської науково-технічної конференції (Дніпро, 24-28 квітня 2023 року). – Дніпро : НТУ «ДП», 2023. – С. 294-296.http://ir.nmu.org.ua/handle/123456789/164026The discovery of cytokinins (American scientists F. Scoot and K. Miller) is associated with research on the cultivation of callus formed from the isolated tissue of the core of a tobacco stem on a nutrient medium. Callus cells in sterile culture have been shown to stop dividing after a certain period. However, when DNA derivatives, which are formed after its autoclaving, are added to the nutrient medium, cell division is restored.encytokininscallustobacco stemкалюсцитокініниArticle
