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。

Using cytohischemical staining methods, with the results of comparison the dynamics of proteins and polysaccharides in the anthe wall cells and colule cells of different developmental phases in female and male flowers, the anormogenesis of anther tapetum in the inflecting phase of from bisexual flower to unisexual flower was observed. In microspore developed phase, the tapetum functions of preserving and transportingmutritive material for microspore development and of secreting callosal enzyme for decompositing callosal cell lost no normal guadrant formed, of being abnormal meiose of pollen mother cells, and then, the stamen aborted selectively in female flowers and pistil in male flower.
利用细胞组织化学染色技术,对雌、雄花雄蕊花药壁细胞及花药内细胞发育过程中多糖及蛋白质动态进行了比较,实验中观察到雌花在从两性至单性花转变时期雄蕊绒毡层在整个发育过程中表现异常,在小孢子发育过程中未能起到贮藏、转运营养物质供小孢子发育及适时分泌胼胝质酶溶解胼胝质壁的功能,并且花粉母细胞减数分裂异常而未形成四分体结构,进而导致雌花雄蕊选择性败育,而雄花中雌蕊组织也发生了选择性败育过程。

Physiologically, our model estimated 2.6 days to reach the single ridge stage, 5.6d to the double ridge stage, 11.3d to the stamen and pistil initiation stage, 13.1d to the anther separation stage, 15.3d to the pollen mother cells stage and 18.2d to the tetrad stage. Phenologically, estimations were 13.1d to reach the jointing stage, 28.7d to the heading stage, 32.8d to the grain filling stage and 51.5d to the maturity stage. PDT was consequently used as a unified scale for measuring developmental progress of different cultivars under different climates and cultural practices.
