An in vitro plant regeneration protocol of Cymbidium faberi from immature seeds was established. The
immature seeds of 50 days old started to form rhizomes 4 months after they were cultured on hormone free
medium. The rhizomes multiplied 5 times when subcultured on the medium containing 1.0 mg l)1
a-naphthalene acetic acid (NAA) for 40 days and more than 90% of the rhizomes initiated shoots within
60 days on the media containing 0.5 or 1.0 mg l)1 NAA plus 2.0 or 5.0 mg l)1 N6-benzylaminopurine (BA).
Plantlets were regenerated when the shoots were planted on the basal medium amended with 1 g l)1
activated charcoal for 50 days and the plantlets grew normally after transplanting.
