AN EFFICIENT IN VITRO PROPAGATION OF ZANTHOXYLUM PIPERITUM

A protocol is described for rapid multiplication of Zanthoxylum piperitum DC. (Rutaceae), an important aromatic and medicinal plant, through shoot-tip explant cultures.
Murashige and Skoog (MS) medium supplemented with various concentrations of N-6-benzyladenine(BA), N-benzyl-9-(2-tetrahydropyrenyl) adenine (BPA) and thidiazuron (TDZ), either single or in combination with α-naphthaleneacetic acid (NAA), was used to determine the rate of shoot proliferation.
N-6-benzyladenine (BA) used at 0.5 mg l^-1 was the most effective in initiating shoot proliferation, producing an average of 23 microshoots per shoot-tip explant after 40 days of culture.
Induction of rooting (98%) was achieved by transferring the shoots to the same basal medium containing 2 mg l^-1 indole-3-butyric acid (IBA). The plantlets were transferred to soil after acclimatization and showed 63% survival.
These results indicate that possible application for the mass production of plantlets is through in vitro culture system in Zanthoxylum piperitum DC.
