子叶的

When the embryonic original cell divided to form multicellur proembryos, the cell wall of the external cell was thickened to form a clear cell boundary to separate from ambient cells that was a phenomenon of isolation The protoderm began to be differentiated in the period of globular embryoid, and the procambium differentiated clearly in period of torpedo embryoid.

正常的球形胚和某些畸形球形胚继续发育，在心形胚或鱼雷胚阶段又出现出畸形胚，可以分为：①无茎端生长点；②原形成层发育不正常；③外形畸形，如有的是连胚，有的呈指状，有的呈叶片状等等。畸形胚有的败育，有的能继续发育，在子叶胚阶段形成畸形的植株。

These observations indicate that the aggregate rER can synthesize and transport protein into cytoplasm and accumulate in cytoplasm.
