thickening meristem

In the early stage, the cellular group of the primordium will differentiate into both of interior and exterior tissues, namely, exterior parenchyma and the saccular primary thickening meristem ( PTM) adjacent to the inside as well as interior parenchyma.

初期，原基细细胞团分化为内外两部分组织：外侧为薄壁组织及紧邻其内的囊状初生加厚分生组织，内侧为薄壁组织。
