    Journal: Zhongguo Zhong Yao Za Zhi; 2007 Jul; 32(13):1273-6. PubMed ID: 17879723.
    Abstract:
    OBJECTIVE: To study the callus induction from leaf, stem segments and stem segments with axillary's bud and the subculture conditions of callus in Camptotheca acuminata. METHOD: The explants were inoculated into the media of MS with different concentrations of 6-BA, NAA and 2, 4-D by orthogonal experiment. RESULT AND CONCLUSION: The optimal medium for callus induction was MS with 6-BA 2 mg x L(-1), NAA 2 mg x L(-1) and 2,4-D 2 mg x L(-1). It had better effects in leaf than in other explants. The induction ratio in leaf reached above 80%. The callus subcultured on the medium of MS with 6-BA 1 mg x L(-1) and 2, 4-D 1 mg x L(-1) grew vigorous and more quickly than that in other media. It was loose, friable in consistency and suitable for cell culture.
