Plant Regeneration through Callus of Korean Native Seosanjong of Zingiber officinale Rosc.

Embryogenic callus cultures of Korean native Seosanjong of ginger(Zingiber officinale Rosc.) were induced through stem explants taken from in vitro shoot-tip cultures. Among the four concentrations of 2,4-D tested in Murashige and Skoog medium, 0.5 and 1 mg/L of 2,4 D was most effective in inducing embryogenic callus. Leaf explants did not express any new morphogenetic response in all 2,4-D concentrations tested. Plantlets transferred to hormone free MS medium were developed and successfully acclimatized under greenhouse.
