Abstract | Culture conditions for high frequency plant regeneration via somatic embryogenesis from cell suspension cultures of Ranunculus kazusensis are described. Zygotic embryos formed white nodular structures and pale-yellow calluses at a frequency of 84.9% when cultured on half-strength Schenk and Hildebrandt (SH) medium supplemented with 0.1 mg l.1 2,4-dichlorophenoxyacetic acid (2,4-D). However, the frequency of white nodular structure and off-white callus formation decreased with an increasing concentration of 2,4-D up to 10 mg l.1, when the frequency reached 25%. Cell suspension cultures were established from zygotic embryo-derived pale-yellow calluses using half-strength SH medium supplemented with 0.1 mg l.1 of 2,4-D. Upon plating onto halfstrength SH basal medium, over 90% of cell aggregates gave rise to numerous somatic embryos and developed into plantlets. Regenerated plantlets were successfully transplanted to potting soil and grown to maturity at a survival rate of over 90% in a growth chamber. The plant regeneration system established in this study can be applied to mass propagation and conservation of this species. |
