\n\tSummary

\n\tStudy on Multiplication in vitro of Panax Vietnamensis Ha et Grushv.

\n\tSmall pieces of Panax vietnamensis were cultured in vitro for callus induction and rapid propagation on the basic medium MS with IBA and 2,4-D at concentration 0.5 - 2.0mg/l. After 60 days, callus were transferred to regenerated medium. Kinetin stimulated regeneration of plantlet from callus at concentration 0.1 - 0.5 mg/l. The medium supplemented with 2,4D (0.5mg/l) + 2ip (0,5mg/l)+ Kinetin (0,5mg/l) was favourable for induction of shoot.

\n\tKey words: Panax vietnamensis, callus, regeneration, 2,4-D, Kinetin.
