    In vitro epicotyl explants from Jatropha curcas were cultured on MS medium with indole-3-butyric acid (IBA) and 6-benzyladenine (BA). Adventitious buds were directly induced from the surface of epicotyl explants under the condition with the combinations of IBA 0.1 mg/L and BA 0.2-0.7 mg/L. Of which IBA 0.1 mg/L and BA 0.5 mg/L induced the highest regeneration frequency. Shoot regeneration from callus required the combinations of IBA 0.5 mg/L with BA 0.1 mg/L, IBA 0.5 mg/L with BA 0.2 mg/L and IBA 1.0 mg/L with BA 0.5 mg/L, and the most suitable combination was IBA 1.0 mg/L and BA 0.5 mg/L. The health adventitious buds and regenerated shoots could be rooted on growth regulator-free MS medium. Regenerated plants with well developed shoots and roots were successfully transferred to greenhouse, without visible detectable variation.
