Abstract

Shoot tips, nodes, internodes and leaves derived from aseptically produced seedlings of Paulownia elongata were cultured on Murashige and Shoog medium (MS) supplemented with NAA and BA. Medium containing 0,1 mg/1 NAA and 0,5 mg/ℓ BA gave the best shoot production from leaf callus (50 shoots per 25 mm2 segment). Shoot tips cultured on medium containing 1 mg/ℓ BA gave rise to a 9,7-fold increase in shoot production in 30 days. The shoots produced could be rooted either on MS medium without growth regulators or treated as straight cuttings and rooted In a 1:1 composted pine bark: vermiculite growing medium.
