egg sac

According to the changes of holdfast occurred in the course of growth and development, M.pyrifera may be divided into four adhesion stages: egg sac, rhizoid hairs, adhesive disc and rhizoid.

在巨藻生长发育过程中，依附着器的变化，可划分为卵囊附着期、假根毛附着期、吸附盘附着期和假根附着期四个时期。

Of most two kinds of variant embryo sac, referred as poly egg apparatus embryo sac ( 53.3%) and double set of embryo sac ( 6.3%) were found.

其中主要的变异有两类，即多卵卵器胚囊（53.3%）和双套结构胚囊（6.3%）。

The results showed that the pET-32a-ADF-3-1E test chickens can produce stronger resistance effect: Insects attack the egg sac of chicken production fell 67.88%, lower intestinal lesion score 67.21%, and the relative weight of chicken rate of 88.36%, ACI value of 166.76.

结果表明，ADF-3-1E重组蛋白免组可产生较强的抗虫效果，卵囊产量下降67.88%，肠道病变记分降低67.21%，鸡的相对增重率达88.36%，ACI值为166.76。

In the poly egg apparatus embryo sac, three egg apparatuses were the majority which could be further divided into three types, namely, 5 2 1 type, 6 2 0 type and 5 3 0 type, based on the whole structure of embryo sac.

多卵卵器胚囊中以三卵卵器胚囊为主。三卵卵器胚囊依胚囊的整体结构可分出5-2-1型、6-2-0型和5-3-0型等3种类型的胚囊。
