Among different organ explants from ginger lily, only sheaths and leaves cultured in VW medium containing 5mg/l 2, 4-D、0.5mg/l BA、3% sucrose and 200ml/l coconut water for 3 months could be induced to form embryogenic callus. It could produce lots of germinated or ungerminated somatic embryos per culture directly from the surface of calli after culture in MS medium containing 4mg/l BA and 0.05mg/l NAA. The shoots could develop into intact plants with vigorous appearance after 2 months in culture.
