ABSTRACT
In this research, regeneration of Valeriana officinalis via
shoot apex was studied. Shoot apex explants were cultured on MS medium supplemented
with different concentrations and combinations of NAA and BAP. The highest callus
induction percentage was obtained in the medium containing 0.5 mg/l BAP and 0.5
mg/l NAA. Multiple shoot were induced from the shoot apex explant of V. officinalis by
culturing them in MS medium supplemented with 0.5 mg/l of 6-benzylaminopurine
(BAP). The explants also induced root formation in MS medium supplemented with
1 mg/l of NAA. The highest fresh and dry weight of callus was observed when 0.5
mg/l BAP was combined with 0.5 mg/l NAA. The addition of BAP up to 1 mg/l to
the medium containing different concentrations of NAA lead to the production
of callus which is compact rather than friable. This result suggests that this
methodology can be applied for rapid propagation of this species.
Key words: Propagation, MS medium, Explant, Culture.
