In the late of April of the second year, male inflorescences unbound and pollinated. When female inflorescences accepted the pollen grains, ovary development was increased in early May. With the development of either of the two ovule, funiculus, integument and nucellus were differentiated. Embryo sac mother cell came into being and the meiosis begins. Then fuctional megaspore developed into matured embryo sac that contain eight nucleuses. In the end of May, double fertilization generated.
次年，4月下旬，雄花序解螺旋散粉，雌花序开花授粉；5月上旬，雌花序授粉后，迅速增长，子房膨大，两个胚珠分化出珠柄、珠被和珠心，珠心中产生孢原细胞；5月中下旬，大孢子母细胞形成并减数分裂，功能性大孢子形成成熟的八核胚囊；5月底，发生双受精。

The reproductive development process of birch was described as follows: Male inflorescences extended from apical bud in early June. In later June, stamen primodium was differentiated in the bract of male inflorescence and the differentiation of bract was generated in female inflorescence. During July, anther layers and archesporial cell were differentiated in anther, then archesporial cell developed into mother microspore cell. Pistil primodium came into being at the same time. In early part of August the meiosis of mother microspore cell started. In later August, mono-nucleus microspore was formed. After September, both male inflorescence and female inflorescence were dormant.
白桦的生殖生长发育过程如下：6月初，雄花序从顶芽中生长出来。6月中下旬，雄花序苞片上分化出雄蕊原基，雌花序分化出苞片。7月，雄花花药分化出花药壁和孢原细胞，孢原细胞演化为小孢子母细胞，雌花序苞腋处分化出雌蕊原基；8月中上旬，小孢子母细胞减数分裂，8月下旬形成单核小孢子；9月后雄花序以单核小孢子状念越冬，雌花序以雌蕊原基状念越冬。

The results indicated that the receptors of estrogen, androgen and progestogen existed in oogonia and oocytes of different developmental stages.
结果表明，不同发育时期的卵原细胞和卵母细胞中都存在雌激素、雄激素和孕激素受体。
