| 摘 要： | 研究了山杜英[Elaeocarpus sylvestris(Lour．)Poir．]带芽茎段的离体培养及植株再生。筛选出最佳培养基：(1)启动培养：Ms+BA 1.0～2.0 mg·L-1 (单位下同)+NAA 0.05+蔗糖3%；(2)愈伤组织发生型丛生苗增殖培养：MS+BA 1.0+NAA 0.5+蔗糖3%；腋芽发生型丛生苗增殖培养：MS+BA2.0+IBA 0.1+蔗糖3%；(3)有效苗诱导培养：MS+BA 0.5+IBA 0.1+GA 1.0+蔗糖3%；(4)生根培养：1/2 MS+IBA 3.0+蔗糖2%。用透气膜封FI比用聚乙烯菌膜生根率明显提高，生根明显提前。

| Abstract: | This paper mainly dealt with the study on shoot organogensis culture in vitro and plant regeneration from sprout explants of Elaeocarpus sylvestris (Lour．)Poir．The results showed that the best media for various stages were as follows：(1) Initial medium：MS+BA 1.0~2.0 mg·L-1 +NAA 0.05 mg·L-1 +3% sucrose；(2)Clump shoot regeneration medium from callus proliferation：MS+BA 1.0mg·L-1 +NAA 0.5mg·L-1 +3%sucrose；Clump shoot regeneration medium from axillary buds：MS+BA 2.0 mg·L-1 +IBA 0.1 mg·L-1 +3%sucrose；(3)Efficiency seedling induction medium：MS+BA 0.5mg·L-1 +IBA 0.1 mg·L-1 +GA 1.0mg·L-1 +3%sucrose；(4) Rooting medium：1/2 MS+IBA 3.0 mg·L-1 +2%sucrose． In root induction culture．the rate of root formation with membrane filter is higher than that of root form ation with common membrane． |
