[Study on the tissue culture and plant regeneration of Pogostemon cablin].

Root tips, leaf segments, stem segments with node and stem segments of Pogostemon cablin (Blanco) Benth. were cultured in vitro. The results indicated that leaf segments and stem segments with node were suitable for callus formation, the frequency of callus induction were over 87.0%. A optimal medium for callus induction was MT + BA 0.5 mg/L + NAA 0.2 mg/L. MT basal medium with BA 0.5-1.0 mg/L were effective to induce differentiation of callus. And at the MT basal medium, the regenerative shoots from Pogostemon cablin could form roots.
