Callus induction and shoot regeneration were obtained from petiole explants in MS with different concentrations and combinations of BAP and NAA in elephant foot yam, Amorphophallus campanulatus Blume Highest (75%) callus induction was observed in MS with 0.5 mg/l BAP + 2.5 mg/l NAA followed by 65% containing 0.5 mg/l BAP + 3.0 mg/l NAA. In most cases, calli were white, brownish and white pinkish. ... [Show full abstract] Highest shoot regeneration (60%) was obtained in MS containing 4.0 mg/l BAP + 1.5 mg/l NAA. The highest number of shoots per
callus was 3.00 ± 0.273. The profuse root development was found in MS with 0.5 mg/l Kn + 1.0 mg/l NAA. Regenerated plantlets were transferred to plastic pots
containing organic loamy soils and after acclimated, the plants showed normal
growth and development.
