【 摘 要 】

Through tissue culture of the stem segments with bud of the 'XuXiang' kiwifruit, a rapid propagation system of 'XuXiang' kiwifruit was established by screening the formula of plant growth hormone concentration which was the best medium for its growth, multiplication medium and inducing-root medium. Results of tests are as follows: The optimal culture medium in the beginning culture phase was MS + 2.0 mg•L-1 6-BA + 0.2 mg•L-1 NAA, the induction rate of adventitious buds with shoot stems by this formula can reach to 86.89%. When the multiplication medium was MS + 1.0 mg•L-1 6-BA + 0.1 mg•L-1 NAA, the number of buds in the stem segment of kiwifruit was the largest and the multiplication coefficient was 5.02. The rooting medium was the 1/2MS medium with IBA concentration of 1.5 mg•L-1, the rooting rate reached 93.56%, and the growth of root was good.
