Micropropagation of Cephaelis ipecacuanha rich.
Shoot cultures of ipecac, Cephaelis ipecacuanha Rich. were established by inoculating seedling nodal explants onto modified Murashige and Skoog's medium supplemented with 8 mg/l kinetin, 0.05 mg/l NAA and 200 mg/l adenine. Upto 12 new axillary shoots per explant were induced after 12 weeks incubation. Shoot cultures were also established by placing shoot tips on medium containing 0.1-0.25 mg/l NAA with 8 mg/l kinetin for 4 weeks and then to shoot multiplication medium for 8 weeks. The multiplication was maintained over several passages. Shoots were rooted using 2 mg/l IBA and normal plants were re-established.
