内胚层

The seed is close globose, seed coat divides 3; Episperm yellow, the flesh is qualitative; In seed coat white, bone; Inside seed coat is gules, flimsy is qualitative, endosperm flesh is qualitative.

种子近球形，种皮分3层；外种皮黄色，肉质；中种皮白色，骨质；内种皮红色，薄纸质，胚乳肉质。

Female flowers: tepals 5 or 6 or several; carpels 2 or 3; ovary superior, 2- or 3-locular; styles 2 or 3, free, persistent; stigma broadly recurved; interstylar nectaries present or lacking; ovules 2 per locule, pendent, anatropous, bitegmic, crassinucellar; micropyle formed by inner integument or by both integuments.

雌花 花被片5或者6或者几个；心皮2或3；子房上位，室2或3；花柱2-3，离生，宿存；宽的柱头下弯；花柱间的蜜腺有或者无；胚珠每室2，下垂，倒生，具双珠被，具厚珠心；珠孔由内珠被或者两层珠被形成。

The ovule is orthotropous and crassinucellate, nucellus is surrounded by three envelopes.

胚珠直生，厚珠心，珠心被内、外珠被以及盖被等三层被膜所包围。

GFP fluorescence was visible early at the 2-cell stage and then became stronger in the blastocysts of all three species. However, the distribution of the GFP signals was restricted to the cells of inner cell mass and no fluorescence was detectable in trophectoderm cells.

结果显示：牛Oct-4启动子驱动的GFP基因在3个物种的2-细胞胚胎就已经开始表达，在囊胚期表达加强且只特异表达于内细胞团中，而不表达于滋养层。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
