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.
