| Abstract: | Davidia involucrata Baill. named Chinese dove tree. It is not only a fomous ornamental plant but also a rare and endangered plant. This paper mainly dealt with the study on shoot organogenesis culture in vitro culture from dormant bud explants of Davidia involucrata. The results showed that the best media for various stages were as follows:(1) The dormant bud induction medium: WPM+BA 2.0 mg·L-1+NAA 0.1 mg·L-1; (2) Clump shoot induction medium: WPM + 2.0 mg·L-1 BA;(3) Clump shoot regeneration medium: WPM+ BA 2.0 mg·L-1+ ZT 0.1 mg·L-1;(4) Rooting medium: WPM + NAA 0.5 mg·L-1. |
