   Tóm tắt

  In Vietnam, root of Paramignya trimera has been known as a traditionally medicinal plant for treatment of various types cancers. For years, over-exploitation has led to the reduced diversity and availability of this plant resource. In nature, the multiplication rate of Paramignya trimera from seeds is very low. In order to increase the rate of multiplication for conservation purpose, in this study, in vitro micropropagation of Paramignya trimera was carried out. The results showed that woody plant medium (WPM) containing 20 g/l sucrose and 7.0 g/l agar was most suitable for in vitro propagation of Paramignya trimera. WPM supplemented with 3.0 mg/l BA, 0.2 mg/l TDZ was optimal medium for shoot formation while WPM supplemented with 1.5 mg/l IBA was suitable for the root induction.
