摘要: 大花翠雀(Delphinium grandiflorum)幼苗初生维管系统的解剖学研究表明,子叶节区是客观存在的,并以子叶节区为中心存在两个过渡区,即向上的子叶节-茎过渡区和向下的子叶节一根过渡区。在子叶节区下部存在原始的外始式二原型十字形单中柱。本研究为进一步揭示毛茛科植物的起源和演化积累一份新资料。

关键词: 大花翠雀, 子叶节区, 初生维管系统, 十字形单中柱

Abstract: It is shown anatomical that there is a cotyledon node zone(CNZ) in the seedling of Delphinium grandiflorum. And there are two transitional regions in the CNZ of D.grandiflorum, namely, cotyledon node stem, transitional region upwards and cotyledon node root transitional region downwards. The primitive exarch and diarch haplostele with cross-like metaxylem exists in the lower part of CNZ. This provides a new information for revealing further the origination and evolution of species of Ranunculaceae.

Key words: Delphinium grandiflorum, Cotyledon node zone, Primary vascular system, Cross-like haplostele
