An improved micropropagation protocol has been developed for teak (Tectona grandis). Nodal explants placed on MS medium supplemented with 22.2 micromolar benzylaminopurine and then serially transferred to fresh medium after 12, 24, 48 and 72 h gave maximum culture establishment (76.8%). Establishment was reduced when explants were retained in the initial culture medium longer than 12 h. Explants collected in May showed maximum (76.8%) response. Placement of the explants on MS medium supplemented with 22.2 micromolar benzylaminopurine and 0.57 micromolar indole-3-acetic acid resulted in the maximum average number of shoots. In vitro raised micro shoots were rooted ex vitro by dipping in indole-3-butyric acid (9.8 mM) for 2 min followed by planting in polyethylene pots containing a soil:vermiculite (1:1 v/v) mixture. This treatment resulted in 77.9% survival of the plantlets. They were weaned in a glasshouse and finally moved to an agro-net shade house.
