A novel protocol has been developed for inducing somatic embryogenesis from leaf cultures of Decalepis hamiltonii. Callus was obtained from leaf sections in Murashige and Skoog (MS) medium supplemented with α-naphthaleneacetic acid (NAA) N⁶-benzyladenine (BA) or 2,4-dichlorophenoxyacetic acid (2,4-D) BA. Nodular embryogenic callus developed from the cut end of explants on media containing 2,4-D and BA, whereas compact callus developed on media containing NAA and BA. Upon subsequent transfer of explants with primary callus onto MS media containing zeatin and/or gibberellic acid (GA₃) and BA, treatment with zeatin (13.68 μM) and BA (10.65 μM) resulted in the induction of the highest number of somatic embryos directly from nodular tissue. The maturation of embryos took place along with the induction on the same medium. Embryogenic calluses with somatic embryos were subcultured onto MS basal medium supplemented with 4.56 μM zeatin 10.65 μM BA. After 4 wk, more extensive differentiation of somatic embryos was observed. The mature embryos developed into complete plantlets on growth regulator-free MS medium. A distinct feature of this study is the induction of somatic embryogenesis from leaf explants of Decalepis hamiltonii, which has not been reported previously. By using this protocol, complete plantlets could be regenerated through indirect somatic embryogenesis or organogenesis from leaf explants in 12–16 wk.
