Summary
A rapid shoot multiplication protocol was established for an important medicinal plant, Vitex negundo L., belonging to the family Verbenaceae, using Murashige and Skoog medium, achieved by shoot multiplication as well as callus regeneration. Shoot multiplication was induced by different concentrations of 1-phenyl-3-(1,2,3-thiadiazol-5-yl)-urea (TDZ), Benzyladenine and 6-furfuryl amino purine separately along with 10% (v/v) coconut water. Green organogenetic callus was obtained by the combined effect of 0.5–2.15 μM TDZ and 1.7 μM indole-3-acetic acid (IAA) along with 1% polyvinylpyrrolidone (PVP), and produced the maximum number of shoots when subcultured onto medium containing 2.7 μM TDZ alone. Elongation of in vitro shoots was observed in MS medium containing 2.4 μM gibberellic acid and rooting was induced by the combined effect of 1.71 μM IAA and 1.62 μM α-naphthalene acetic acid.
