Abstract

Axenic seedling-derived two- to three-node stem segments of Nepenthes khasiana Hook.f. were successfully cultured on Woody Plant Medium containing 2.2 μM benzyladenine to produce a 0.5–1.5 cm axillary shoot from each node in 7–8 weeks. The rapid growth along with the axillary branching of this shoot enabled amassing of 6–12 shoots during subculture. Excised shoots transferred to basal medium or rooted in medium containing 2.7 μM naphthaleneacetic acid produced typical pitchers at leaf tips. Rooted plants were established in pots at 90–95% survival rate.
