漆树花器官中漆汁道的分布和发育

本文报道了漆树花器官中漆汁道的发生和发育方式。研究结果表明,萼片、花瓣和子房中漆汁道是以裂生方式产生的。但发育到一定阶段,漆汁道腔周围的分泌细胞有与漆汁道中分泌物相似的染色反应。随后,这些细胞脱入腔道,逐渐解体。与此同时,暴露在腔道周围的薄壁细胞逐渐变成分泌细胞。因此,在漆树花器官(雄蕊除外)中,漆汁道的发育是裂溶生的。

Study Reports Distribution and Development of Secretory Canals of Lacquertree in Flowers of Rhus verniciflua

Distibution and development of secretory canals of lacquer tree in flowers of Rhus verniciflua were studied.According to development anatomic observations,primarily,the canals developed iysigenously in pe- rianth and ovaries,and then,secretory cells ling in the canals bred from the neighboring cells and disintegrated in the canals,latter became secretory cells gradually.It suggests that the canals may be sehizolysige- nous origin in the perianth and ovaries of Rnus verniciflua.
