Abstract: Cercidiphyllum japonicum is an endangered plant in China, possesses the high economic and appreciatory value. This papermainly dealt with the study on shoot organogenesis culture in vitro culture from sprout explants of Cercidiphy llum japonicum. The results showed that the best media for various stages were as follows: (1) Axially bud induction medium: MS +NAA 0.01 mg·L - 1 ; (2) Clump shoot induction medium: MS +BA 1.0 mg·L - 1 ; (3) Clump shoot regeneration medium: MS + BA 2.0 mg·L - 1 + 2,4-D 0.01 mg·L - 1 ; (4)Rooting medium: 1/2MS + IBA 1.0 mg·L - 1.
