FIELD: plants biotechnology.
SUBSTANCE: invention is a method of propagating Decaisnea fargesii by in vitro culture, including isolating apical and lateral buds, using stem fragments 1 cm long with 1–2 axillary buds as primary explants, sterilization, planting on nutrient media, propagation of microshoots, their subsequent rooting, adaptation of regenerated plants to ex vitro conditions. After adaptation to non-sterile conditions and growing, standard paulownia seedlings with a closed root system are obtained. The proposed method of paulownia clonal micropropagation makes it possible to obtain a high multiplication factor and, as a result, the required number of aligned high-quality seedlings.
EFFECT: planting material is genetically homogeneous, the period of cultivation is reduced and the possibility of carrying out work throughout the year is provided.
