摘 要 ：本文按照子叶节区理论(Cotyledon node zone theory)研究结果表明， 甜菜幼苗的子叶节区类型为顶枝伸长型(Telome elongation type)。 甜菜肥大直根采用幼苗分区定位法明确其根头部由上胚轴苗区发育而成； 根颈部与根体是由长的顶枝伸长型的子叶节区发育而来； 至于下面短的根尾， 是下胚轴发育的产物； 甜菜真正的根并不肥大

Abstract:The traditional zonation method and terminology of plant seedlings based on tradi-tional morphological and anatomical theories and methods were challenged by the newly developed cotyledon node zone(CNZ) theory. Using sugar beat (Beta vulgaris) as material, it was found that its seedling belongs to t
