Induction of Morphogenesis of Adventitious Bud Explants of Fast-Growing Woody Plants of the Genus Paulownia

Abstract

Recently, the interest of the scientific society has focused on the study of various forms and hybrids of Paulownia. The Shan Tong hybrid has been introduced in the Chechen Republic and work is underway on the introduction of Pao Tong Z07, both hybrids are frost-resistant -20 ...-30 0C. It is known that the induction of morphogenesis in most cultures is a difficult task, since it is accompanied by problems of selecting the optimal composition of the nutrient medium, as well as the type of explant being initiated, which takes a lot of time. The paper presents the results of the research of the laboratory “Biotechnology of agricultural plants for regenerative agriculture” for 2021-2022 on the cultivation in vitro of fast-growing plants with high sequestration potential from the genus Paulownia. The results of experiments to study the effectiveness of sterilizing substances – hypochlorites on the survival of explants initiated from the axillary kidneys are presented. A positive effect was noted in the induction of morphogenesis of adventitious kidneys from axillary kidneys in Paulownia Shan Tong and Paulownia Pao Tong Z07. The optimal protocol of the nutrient medium for the introduction and multiplication of micro-plants is given, the concentrations of plant growth regulators 6-BAP and BCI to increase the reproduction coefficient of plants Paulownia Shan Tong and Paulownia Pao Tong Z07 are also studied.
