Propagation of paulownia elongata s. Y. Hu by axillary shoots

Abstract

Paulownia elongata is an ornamental, fast-growing species and resistant to urban conditions. It was successfully adapted to the growing conditions in Serbia. Twelve-year-old elite tree, originating from a plantation in Bela Crkva was used as stock plant for the experiments. In vitro culture was successfully established using disinfection of nodal segments of annual shoots with 0.1% HgCl2 for 10 min. The most favorable shoot multiplication response (6.7 shoots per explant) was recorded on MS medium supplemented with 6 mg l(-1) BA and 0.5 mg l(-1) IBA, and rooting was successful (95%) on MS medium with 0.8 mg l(-1) of IBA and the same amount of NAA.
