摘　　要：经镰形角果毛莨(Ceratocephalus falcatus)幼苗的初生维管系统研究后又一次证实被子植物的真中柱,既非来自管状中柱,也非来自原生中柱,而系来自子叶节区保留的单中柱;且在其子叶节区可看到自中始式单中柱向内始式真中柱和散生中柱变化之过程。Through studies on the primary vascular system of Ceratocephahis falcatus seedling, it was confirmed that the eustele of angiosperm had evolued neither from siphonostele nor from proto-stele, but from the haplostele which remained in cotyledon node zone. It could be seen that the e-valuation process of stele was from haplostele to eustele and atactostele.
