For the bud directly differentiation , the suitable culture medium was MS+BA 2mg/L +NAA 0.2mg/L or MS+TDZ0.01mg/L +NAA0.2 mg/L, of which the induction rate was 88% and 100% respectively. An efficient tissue culture system has been developed with the bud of mature seed of Aesculus hippocastanum L. as explants . Buds were induced from 2cm high young plantlet cultured on MS medium supplemented with 0.6 mg/L 6-BA plus 0.1mg/L or 0.4~0.6mg/L ZT plus 0.1 mg/L NAA for 15 d, and the induction rate was 100%, the mean No. of buds was 35.7; The combination of MS+0.2mg/L 6-BA +0.1mg/L NAA + 10mg/L AD was the suitable culture medium for elongation of the buds.
