Assay of procyanidins in episperm of sorghum seed from various area in our country was done .

本文对我国高粱种子不同部位的原花青素的含量以及高粱主产地高粱种子外种皮中原花青素的含量进行了测定；

Antifungal Activities of the Extracts of Gingko Episperm against 4 Plant Pathogenic Fungi

银杏外种皮提取物对4种植物病原真菌的抗菌活性

The third pass debranned the episperm and a part of nucellar layer .

第三道碾皮主要碾除了麦粒的种皮及部分珠心层。

Study on the episperm micro-morphological characteristics of subgenus Soja in Glycine

大豆属Soja亚属种皮微形态特征的研究

Difference of cell arrangement and shape of episperm , mesosperm and endopleura became obvious during seed development .

在种实发育过程中，外种皮、中种皮和内种皮细胞排列及形状的差异逐渐明显。

Effects of Procyanidins from Sorghum Episperm on Activity of α - amylase and Protease by DSC

高粱原花青素对α-淀粉酶和蛋白酶活力影响的DSC研究

The content of tannin in episperm was the highest , the hypocotyl and endocarp followed .

种皮中最高，其次是胚轴和内果皮；

Ratio of length to width of endopleura was higher than that of episperm and mesosperm .

其中内种皮的长宽比值变化高于同时期的外种皮和中种皮。

There was , to some extent , some relevance between episperm and the colour of embryo , and the time of changing colour of episperm is 2-3 earlier than that of embryo .

种皮和胚的颜色变化过程中具有一定的相关性，种皮开始变色时间比胚早2-3d。

The fresh weights of episperm began to increase rapidly at 50 d after pollination , and the dry weights increased later . The water contents of episperm are higher in earlier stage , and then declined gradually .

银杏外种皮鲜重在授粉后50d开始迅速增长，而干重的迅速增长期稍晚于鲜重；银杏外种皮水分的含量，在种实发育前期较高，随后逐渐降低。

The amyloids of episperm are surrounded by a network structure in earlier stage . With the increasing of starch granules , the size of plasmid increased and the network structure disappeared gradually . Then the starch formed as a free state in the cytoplasm .

银杏外种皮中的淀粉体在发育初期周边有网状体结构存在，随着淀粉粒的增大，质体的体积不断增加，其周围网状结构逐渐消失，淀粉体形成并游离在细胞质中。

The results showed that the seeds would sprout by dewaxing episperm and soaking seed to hasten germination , The rate of germination of seeds was relatively high to come up to 63.2 % with the method of underground stratify in all pretreatments .

种子发芽需种皮去蜡和温水浸种催芽，发芽率以野外地下沙藏的方法相对较高，达到63.2%。种皮中最高，其次是胚轴和内果皮；
