Increasing proportions of the tree's pollen reduced the percentage of full seed and retarded growth of the epicotyl . 树木本身花粉比例的增加使饱满种子的比例降低，并使胚轴生长缓慢。

Plantlet regeneration and agrobacterium - mediated transformation of peanut with epicotyl as explants 花生上胚轴为外植体的植株再生及转化研究

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。
