DING Lan, LIANG Cui-xia, YANG Yong-li (College of Life Science, Northwest Normal University, Lanzhou 730070, Gansu, China)  
Four kinds of tissue of Lycopersicon Esculentum var. Cerasiforme, hypocotyl, leaf, shoot-tip, and stem with a lateral bud cut from cultivars "Hong Bao-shi" are cultured on MS medium with BA and JAA at different levels. The results show that the optimal induction media of buds are MS + 1 .0- 2.0 mg/L BA + 0.5 mg/L IAA, MS + 2.0 mg/L BA+0.2 mg/L LAA, MS + 1.0.- 2.0 mg/L BA + 0.1 -.0.5 mg/LIAA. Proliferation medium of shoots is MS + 1.0 mg/L BA + 0.5 mg/L IAA. Induction of mot is better for shoots in MS + 0. 1 mg/L NAA. The cuttage of the stem in vitro are carried on MS + 0.005 -0.01 mg/L NAA or MS without hormone. The rate of proliferation of the shoots is 5.
