The inner integument

In addition , the inner integument cells developed into endothelium .

此外，珠被内表皮细胞发育为珠被绒毡层。

The major part of the inner integument is absorbed after about 21 days of the blooming date ( the cotyledon begin to differentiate within the first ten days of May ) .

开花授粉、授精后，珠被发育为种皮时，内珠被逐渐被吸收，大约在开花后2P天左右（5月上旬，子叶开始分化时），内珠被绝大部份被吸收。

It was found that the semi-permeable layer was formed by the outer periclinal wall of the inner integument thicken and identified the formation time of this layer for all the seeds .

并发现供试种子半透层是由内珠被外侧细胞细胞壁加厚形成的，确定了各种禾草半透层形成的时期。

At this moment , the exterior integument develops the testa which is brown and fleshy ; the inner integument develops the endothelium which is hard . 2 .

此时，外珠被发育形成外种皮，褐色肉质；内珠被形成内种皮，石质化、坚硬。

The pistil was composed of five carpels , stigmas and styli separated , the ovary was coadnate , basal placenta , it had only one circinotropous ovule , the ovule was crassinucellate and had two layers of integument , the micropyle was formed by the inner integument .

雌蕊由5心皮组成，柱头、花柱分离，子房合生，1室，基生胎座，胚珠1个，拳卷型，双珠被，厚珠心，珠孔由内珠被形成。
