上胚轴 meaning in English
epicotyl
Examples
- Such seedlings are characterized by having elongated hypocotyls or epicotyls .
这样的幼苗具有伸长的下胚轴或上胚轴的特征。 - 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 - 7 - 10 days " seedlings after the seeds germinated , the meristem in the stem apex functioned to form true leaf primordium , meanwhile , the vessel elements which differentiated from parenchymatous cells of the middle and upper portion of the cnz connected with the vessel elements from procambium of epcotyl - shoot region
种子萌发7 - 10天，幼苗的茎端分生组织活动形成真叶雏形，此时由子叶节区中、上部薄壁细胞的转分化形成的导管分子与上胚轴-苗区原形层形成的导管分子发生连接。 - 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。
