Different species and hybrids of Paulownia are valuable technical, bioenergetic, medicinal and decorative crops cultivated all over the world. We investigated in vitro microclonal propagation of hybrid Paulownia elongata × Paulownia fortunei via auxiliary buds activation. The phytohormone regulation of the growth and development of cuttings was studied on the base of modified MS medium with different concentrations of 6-benzylaminopurine with and without 0.2 mg/l 3-indole-acetic acid. The addition of 2.0 mg/l alone appeared to be optimal for new shoot formation. The best for rooting was ½MS supplemented with 1.0 mg/l indole-3-butyric acid. The mass loss of wood at the stage of cellulose decomposition was ranged from 57.3 to 63.9% in two versions of soil profiles containing water retention layer. The initial results allow estimating P. elongata × P. fortunei as a plant which demonstrated stable adaption potential as bioenergy tree.
