Examples
- According to the space - tim e maturation during the development of the vessel elements in primary vascular system : the vessel elememts of the cotyledons and the lower portion of cnz formed firstly , then downward hypocotyl - root zone , at length , the vessel elememts of the upper and middle portion of cnz and epicotyl - shoot region connected with each other , the result uphold the seedling partition model that divides seedling into cnz , hypocotyl - root region and epicotyl - shoot region
根据金鱼草幼苗初生维管系统导管分子发育的时空性，即子叶和子叶节区下部导管分子先形成，然后向下形成下胚轴-根区的导管分子，最后子叶节区中、上部与上胚轴-苗区的导管分子再发生连接，据此支持将幼苗分为子叶节区、下胚轴-根区和上胚轴-苗区的幼苗分区模型。 - The results showed that the vessel element did n ' t differentiate after the seeds had imbibied for 6 hours ; 6 hours after seeds germination , two loci ? ne below the middle portion of the cotyledon and the other in the lower portion of cotyledon - node zone ( cnz ) initiated the differentiation of vessel element simultaneously , then elongated towards the cotyledonary apex and hypocotyl - root region respectively ; eventually the two promoter loci began to interconnect through vessel elements
结果表明：种子吸涨6h ，未有导管分子的分化；种子萌发后6小时期间，自子叶中部偏下方和子叶节区下部的两个位点同时启动导管分子的分化，并分别向子叶叶尖和下胚轴-根的方向延伸；尔后，在发生两个启动位点之间发生导管分子的连接。
