<正>以“马可”百合（Lilium bulbiferum cv.‘Marco Polo’）鳞片为起始外植体，MS为基本培养基，以不同激素成分及不同浓度水平来诱导“马可”百合产生小鳞茎。结果表明：“马可”百合的诱导可由外植体直接产生小鳞茎而分化成苗。诱导“马可”产生小鳞茎的最佳外植体为鳞茎内部的鳞片，将其作为不切开处理，并以鳞片远轴面紧贴培养基的方式进行接种，在MS十6~BA（1.0mg/L）+IBA（0.3mg/L）培养基上进行诱导培养，其平均分化系数达2.52。“马可”百合最佳扩繁增殖培养基为MS+6-BA（0.3mg/L）+1BA（0.3mg/L），小鳞茎的增殖系数可达2.60。采用1/2MS+6-BA（0.3mg/L）+IBA（0.7mg/L）的培养基对“马可”进行生根培养，根条数可达8.0，生根率为100%。“马可”生根苗应用质量分数为50%多菌灵800倍液进行消毒处理，移植于河泥和珍珠岩的体积比为7：3的基质中，成活率可达98%。

Hydroxyalkyal lignin was synthesized from alkali lignin with propylene oxide. Then it was epoxided by epichlorohydrin catalyzed via boron trifluoride etherate to form ligninbased epoxy resin. Using lignin-based epoxy resin and organic-montmorillonite (OMMT), lignin-based composite was prepared by intercalated polymerization. The compatibility of lignin- based epoxy resin and OMMT was excellent. When T31 and methyl hexahydro-phthalic anhydride were used as a curing agent, the tensile strength and impact strength of ligninbased epoxy resin/OMMT composite were stronger than lignin-based epoxy resin without OMMT. Thimbleful OMMT could increase the toughness and intensity of the lignin-based epoxy resin.
