摘　　要：[Objective] This study aimed to establish a technology system for tissue culture and rapid propagation of Illciaceae ornamental plants. [Method] Effects of medium components and anti-browning agents on the survival and growth of shoot tips were investigated by using apical buds of IItciaceae plant Haierlian as experiment material and MS as basic medium. [Result] The results showed that apical buds at the early germination period in spring were the most suitable explants for tissue culture of IIIciaceae plant Haierlian. Sterilization with 0.1% HgCI2 for 6 min achieved the best effect, while conventional surface-sterilization with ethanol would affect the survival of explants. The optimal medium for primary culture was MS-D （with modifications in major elements and organic components） ＋ anti-browning agents （equa~ volume） ＋ 2.0 mg/L of 6-BA ＋ 0.5 mg/L of NAA. The optimal subculture medi- um was MS-F （with modifications in inorganic and organic components） ＋ anti-brown- ing agents （equal volume） ＋ 2.0 mg/L of 6-BA ＋ 0.1 mg/L of NAA. [Conclusion] This study laid the foundation for establishment of tissue culture and rapid propagation technology system for Haierlian.[目的]探讨八角科观赏植物组织培养及快繁技术体系。[方法]以八角科植物"孩儿莲"的顶芽为研究对象,以MS培养基为基本培养基,调查了培养基组成及抗褐化剂对顶芽茎尖存活和生长发育的影响。[结果]春季萌动初期的顶芽是八角科植物"孩儿莲"组织培养的最适外植体材料;灭菌条件以0.1%HgCl2溶液处理6min为宜,而常规酒精表面消毒会影响外植体存活;适宜的初代培养基为改良MS(改良大量元素与有机成分)+1倍量抗褐化剂+2.0mg/L6-BA+0.5mg/LNAA,继代培养基为改良MS(改良无机成分与有机成分)+1倍量抗褐化剂+2.0mg/L6-BA+0.1mg/LNAA。[结论]该研究结果为"孩儿莲"组培快繁技术的建立奠定了试验基础。
