摘要: 大白菜是子叶出土幼苗,子叶节区下部具木质部中部凹缢的中始式二原型单中柱,特称芸苔型(Brassica type)。作者在大白菜幼苗子叶节区中部也发现了属于管状中柱范畴的疏隙中柱阶段(solenostele stage),从而进一步证明管状中柱和疏隙中柱在种子植物体内并非毛茛科某些属(Garidella、Nigella)所特有,至少在十字花科的芸苔属(Brassica)也存在。

关键词: 大白菜, 疏隙中柱, 芸苔型

Abstract: Brassica pekinensis has an epigaeous seedling, and there is a xylem in the low part of Cotyledon node zone, and the mesarch and diarch hoplostele which is sunken in the middle part is termed Brassica type in this paper.The author also finds the solenostele stage that belongs to siphonostele in the middle part of CNZ.This discover further prove that solenostele and siphonostele are not only the features of some genus of Ranunculaceae in the body of spermatophete, and they exist in the Brassica of Cruciferae, too.

Key words: Brassica pekinensis, Solenostele, Brassica type
