青岛百合次生鳞茎形态发生学研究

Study on Secondary Bulb Morphogenesis of Lilium tsingtauense

采用解剖学方法研究了青岛百合次生鳞茎的形态发生过程。结果表明：次生鳞茎形态发生起源于鳞片近轴面基部向上第5～10层薄壁细胞，而非愈伤组织，为器官型形态发生。次生鳞茎发生过程可分为细胞脱分化阶段、生长锥形成阶段、小鳞片原基和根原基形成阶段、次生鳞茎形成阶段。

Secondary bulb morphogenesis of Lilium tsingtauense was observed in present paper. The results showed that the secondary bulb originated from the 5th - 10th parenchyma cells of scale base not callus tissue. It belonged to organ - type pathway. The process of secondary bulb morphogenesis was divided into four stages： cell dedifferentiation stage, apical meristem formation stage, ramentum primordium and root primordium formation stage, secondary bulb formation stage.
