Tissue culture technics of Liriodendron chinese (Hemsl.)Sarg. × Liriodendron tulipofera Linn. were studied in this paper. The optimal inducing medium was MS+6-BA 1.0 mg/L+IBA 0.1 mg/L+GA3 0.5 mg/L+3%sucrose+0.7%agar powder. The optimal multiplication medium was MS+6-BA 0.5 mg/L+IBA 0.1 mg/L+3%sucrose+0.7%agar powder. The highest multiplication rate was 3.0. The feasible light intensity was 1 000~2 000 lx. The optimal rooting medium was 1/2 MS+IBA 0.05 mg/L+2%sucrose+0.6%agar powder with the rooting rate over 67%and the average roots number of 2.3.
