In vitro propagation of an anticancerous drug synthesizing plant, Ophiorrhiza prostrata D. Don, was established through indirect somatic embryogenesis. Friable embryogenic calluses were initiated from O. prostrata leaf and internode explants on Murashige and Skoog (MS) media supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) either
alone or in combination with N6-benzyladenine (BA) or kinetin (KIN). Somatic embryos were developed after subculture of the friable calluses onto half strength
MS media containing 0.45 or 2.26 μM 2,4-D alone or in combination with BA or KIN. Medium supplemented with 2.26 μM 2,4-D and
2.22 μM BA was optimal, supporting the production of a mean of 5.8 globular embryos. Subculture of globular embryo-bearing
calluses on half strength MS medium without growth regulators produced the highest embryo frequency, and the majority of them
developing to early torpedo stage. Somatic embryos underwent maturation and converted to plantlets at high frequency (90 %)
on half strength MS medium supplemented with 0.44 μM BA. Somatic embryo-derived plantlets with well-developed roots were established
in field conditions with a 90 % survival rate. 相似文献

Summary This study describes a protocol for in vitro propagation of Chonemorpha grandiflora (Roth) S.M. & M.R. Almeida (Apocynaceae) through axillary bud proliferation and rooting. For shoot induction, the combination of 13.3 μM
N
6-benzyladenine (BA) and 2.46 μM indole-3-butyric acid (IBA) in Murashige and Skoog (MS) medium was better than other growth regulators. Liquid medium was
superior over solid medium for root formation and growth. IBA was more effective than other auxins for root induction. Addition
of silver nitrate in the presence of IBA significantly increased the number, length, and branching of roots. Shoot tips encapsulated
in medium containing 0.49 μM IBA and 11.7 μM silver nitrate exhibited 95% conversion to plantlets. This protocol enables the production of 250 plantlets from a single
nodal explant within 7 mo. Plantlets showed 90% survival after acclimatization in soil and were morphologically similar to
the source plant under field conditions. 相似文献
