title: Somatic embryogenesis from leaf explants of Australian fan flower, Scaevola aemula R. Br.
abstract: Somatic embryogenesis from leaf explants of Scaevola aemula R. Br. was achieved. Somatic embryos were induced from explants cultured on MS medium supplemented with 0.2 mg/ 2,4-dichlorophenoxyacetic acid and 0.2-0.5 mg/l 6-benzylaminopurine (BAP). Various developmental stages of somatic embryos were found on this medium-from globular embryos to germinated embryos. The transfer of globular embryos to MS medium containing 0.5 mg/l BAP resulted in a high frequency of shoot regeneration. Leaf explants cultured on MS medium containing different combinations of BAP and alpha-naphthaleneacetic acid formed adventitious shoots and roots. Histological examination confirmed the process of somatic embryogenesis. Induction of somatic embryogenesis in Scaevola provides a system for studying embryogenesis in Australian native plants and will facilitate the improvement of these plants using genetic transformation techniques.
