Shoot regeneration via direct organogenesis from in vitro derived leaves of mulberry using thidiazuron and 6-benzylaminopurine

Abstract

A brief culture of mulberry leaves for 8-10 days on MS medium with 18.17 μM TDZ followed by transfer to 8.88 μM BAP supplemented medium triggered high frequency shoot organogenesis (77.6-89.2%) and favoured shoot elongation in Morus spp. Shoot proliferation was highest in the presence of 2.22 μM BAP with induction of 9.4-10.6 shoots per culture. High frequency of root induction (76.0-86.6%) was observed on medium supplemented with 0.49 μM IBA whereas increase in the level of IBA (4.92 μM) resulted in induction of roots along with development of callus from the base of the shoots. The regenerated plants established in soil at higher frequency in rainy season compared to winter and summer. © 2005 Elsevier B.V. All rights reserved.
