The dormant wood of Kalopanax septemlobus in Changbaishan were used as experimental materials .The experiment was made to find out the best tissue culture process and culture medium .The results showed that the leafstalk was the suitable explant and tissue culture of Kalopanax septemlobus required different kinds of culture medium in different phases .The optimal initiation medium is WPM +2, 4-D0.50 mg/L +NAA0.1 mg/L, the rate of iniation is over 90%; The callus redifferentiation medium is WPM +KT2.0 mg/L+6 -BA0.50 mg/L+NAA0.1 mg/L, the rate of redifferectiation is 82%; The proper rooting medium is WPM +NAA 0.5 mg/L, and the rooting rate can be up to 85%.
