He experiment proved that pre-implantation embryos are more sensitive than post-implantation ones, suggested TCDD may exert its effect before implantation, or at this process. 3. The toxicity of TCDD on the early embryo can be of omnifarious. It can strongly inhibit DCR, which represent mother toxicity; It cause un-synchronizated cleavage of pre-implanted zygote and pre-implanted embryo loss; It also decreases implantation sites in the uterus, and continued to effecting the uterus of pregnant mouse, cause the decreased number of fetus before birth. 4. TCDD exposure changed reproductive hormone level of pregnant mouse.

CDD对胚胎的毒性影响可能是多方面的：强烈抑制子宫蜕膜细胞反应，表现出典型的母体毒性；虽然没有影响胚胎转运速度，但造成着床前胚胎的丢失和发育不同步；早期染毒降低了第9天的胚胎着床数，同时使出生前第18天胚胎成活数继续减少。

本研究应用透射电镜及DNA荧光技术对天竺葵和杜鹃的成熟配子体以及在受精以后雄性细胞器的存在和分布进行了系统的细胞学研究，阐明了这两种植物中雌性生殖单位的超微结构特点及雄性和雌性细胞中质体和线粒体在受精作用中的传递。

Then one ovule degenerated, the other which contained zygote kept on developing. Embryo undergone proembryo and globular embyo stage in early part of June. Heart stage embryo developed into torpedo stage, and meanwhile nuclear endosperm formed cellwalls in later June. Birch Fruit matured in July..

此后，一个胚珠退化，另一个含有受精卵的胚珠继续发育。6月上旬，白桦胚正经历原胚球形胚阶段。6月下旬核型胚乳细胞化，心形胚发育为鱼雷胚。7月，白桦果实成熟。
