摘要:

采用解剖学方法研究东方百合鳞片扦插繁殖中小鳞茎的组织发生过程。结果表明:小鳞茎的形态发生起源于鳞片近轴面基部的几层薄壁细胞,细胞脱分化后形成分生组织,再经过器官发生途径形成小鳞茎,属于外起源。小鳞茎发生过程可分为未分化期、启动期、生长锥形成期、小鳞片原基和根原基形成期、小鳞茎形成期。

Abstract:

Bulblet morphological courses of Oriental lily during scale cutting propagation were observed in present paper. The results showed that bulblet formation by organogenesis which originated from the parenchyma cells on scale base. Bulblet formation belongs to external origination. The process of bulblet morphogenesis was divided into five stages:no differentiation stage,initiating stage,apical meristem formation stage,leaflet primordium and root primordium formation stage,bulblet formation stage.

Key words: Oriental lily scale cutting bulblet morphogenesis
