In vitro morphogenesis of Ceratozamia hildae and C. mexicana from megagametophytes and zygotic embryos

Abstract

Organogenesis and somatic embryogenesis were induced from megagametophyte and zygotic embryo explants of 2 cycad species, Ceratozamia hildae and C. mexicana, cultured on modified B5 medium containing kinetin (0–13.9 μM) and 2,4-d (0–9.0 μM). Organogenesis occurred from megagametophyte explants of both species on the range of media tested. Somatic embryogenesis was largely restricted to zygotic embryo explants. Somatic embryos germinated in vitro: however, rooting of adventitious shoots was unsuccessful.
