Abstract : Periwinkle (Catharanthus roseus) has gained unique position in the modern day medicinal arena due to its alkaloids. Important among them are vinblastine and vincristine, the anti-cancer agents. But its low yield per hectare makes it prohibitively expensive. Hence, in-vitro techniques using different types of explants is resorted to. Nodal explants showed 100% callusing after 11 days. The calli were friable, loosely arranged and white with plant growth regulators (PGRS) BAP (0.5 mg/l) and NAA (1.0 mg/l).
Key words : 6-Benzyladenine (BAP). Catharanthus roseus explants. MS medium. Naphthalene acetic acid (NAA).
