摘 要 ：对石刁柏（Ａｓｐａｒａｇｕｓｏｆｆｉｃｉｎａｌｉｓ）体细胞胚发生过程中细胞的超微结构进行了观察，非胚性细胞内液泡大，大量的自体吞噬泡出现，胚性细胞内细胞核大，核移中，核仁结构明显，线粒体、质体、核糖体、高尔基体、内质网等细胞器增多，淀粉、脂滴积累，有较活跃的自体吞噬现象，梨形细胞内质体向叶绿体转变。

Abstract:The ultrastructural studies changes of somatic embryogenesis in Asparagus officinalis were studied.There was central vacuole in unembryogenic cells.Alot of autophagic vacuoles were ob- served.In the embryogenic cells some small vacuoles,a large nucleus
