对茄子幼苗的初生维管系统以子叶节区理论为指导，进行解剖学研究。经研究表明，其初生维管组织的器官间过渡形式，属顶枝伸长型的子叶节区。子叶节区下部较短，中部较长，故只有一个极短的子叶节区—根过渡区和上胚轴苗区，与子叶节区之间的维管组织连接区，其维管组织的转化，主要存在于子叶节区中部与子叶之间 The primary vascular system of eggplant seedlings is guided by cotyledonary node theory and studied anatomically. The study shows that the primary vascular tissue of the inter-organ transitional form, is a top-cotyledon cotyledonary node. The cotyledonary node is shorter in the lower part and longer in the middle part. Therefore, there is only one extremely short cotyledonary node-root transition zone and hypocotyls zone, , Mainly in the cotyledonary node between the middle and cotyledons
