The objective of this study was to increase the formation rate of embryos from suspension cultures of Taranoki (Aralia elata). The suspension cultures were prepared from leaf-derived calli. Of the various culture durations, 30 days of culture yielded the best growth of cell suspension cultures in a BT liquid medium supplemented with 2,4-D. Somatic embryogenesis has never been observed without the addition of exogenous plant growth regulators (PGRs). The highest percentage of somatic embryo formation (93.3%) was observed in a BT liquid medium supplemented with 1.0 μM BAP+5.0 μM 2,4-D. The PGR-free semi-solid BT medium showed the highest regeneration frequency of cotyledonary-shaped embryos (100%).
