Abstract: The leaves and stem segments of lemon-scented geranium were cultured in tubes as explants. The results showed that stem segments had a better effect in inducing differentiation. The most appropriate culture mediums were:(1) the medium of inducing clump sprouts was MS+BA 2.0 mg·L-1+NAA 0.1 mg·L-1;(2)the media of step-generation culture was MS+BA 1.0 mg·L-1+NAA 0.1 mg·L-1; (3)the root-producing medium was 1/2MS.
