Adventitious shoots and roots were directly formed from young flower bud explants of Agapanthus africanus on Murashige and Skoog (MS) medium containing 30 g¥L-1 sucrose, 2 g¥L-1 gellan gum, and kinetin or thidiazuron at 1 mg¥L-1 in combination with 1 mg¥L-1 NAA. Friable calli with a high rate of plant regeneration were also induced by culturing the explants on medium containing NAA, picloram or 2, 4-D at concentrations varying from 1 to 10 mg¥L-1, especially at low concentrations of picloram or

Nodular compact calli were also formed with friable calli on medium supplemented with 2, 4-D or picloram. The compact calli induced with 1 mg¥L-1 picloram developed into somatic embryos. In both shoot and embryo regeneration systems, complete plantlets were obtained when they were transferred onto a medium containing no plant growth regulator.
