Plant regeneration through somatic embryogenesis on Holostemma ada-kodien, a rare medicinal plant
2003
Martin, K.P.
Plant regeneration through indirect somatic embryogenesis has been established on Holostemma ada-kodien Schult. Type of auxin significantly influenced somatic embryogenesis. Friable callus, developed from leaf, internode and root explants on Murashige and Skoog (MS) medium supplemented with 2,4-D (1.0 mg l-1), was most effective for the induction of somatic embryos. Subculture of the friable callus developed on 2,4-D (1.0 mg l-1) onto solid or liquid 1/2 MS medium with 0.1 or 0.5 mg l-1 2,4-D turned the callus embryogenic. Suspension cultures were superior to static cultures (solid medium) for the induction of somatic embryos. Transfer of embryogenic callus to liquid 1/2 or 1/4 MS medium with lower levels of 2,4-D (0.05-0.1 mg l-1) induced the highest number of somatic embryos. An average of 40 embryos were obtained from 10 mg callus. Fifty per cent embryos exhibited maturation and conversion upon transfer to 1/10 MS basal solid medium. Plantlets were established in field conditions and 90 per cent survived.
