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 first split of microspore mother cell is observed after one week after beginning of temperature arised under high temperature but the split of secondary sporogenous cell doesn't be found. The split of secondary sporogenous cell is still found after one week but the first split of microspore mother cell is observed after 12d under low temperature. Formating speed of male gametophyte is affected by temperature.
在高温条件下，开始加温1周后即看到小孢子母细胞进行第一次分裂，未观察到次生造孢细胞的分裂；在低温条件下，1周后仍能看到次生造孢细胞的分裂，12d后才看到小孢子母细胞进行第一次分裂。

Under normal temperature, anthers of not fertility restoration stopped developing in the stage of archesporical cell; 1-2 comers of a few anther could differentiate and form archesporical cell, sporogenous cells and microspore mother cell, but microspore mother cell disintegrated on the first meiotic division.
常温下，未发生育性恢复的花药在孢原细胞期就停止发育；少数花药1~2个角隅处可分化形成孢原细胞，造孢细胞，花粉母细胞，但花粉母细胞在减数分裂的第一次分裂时解体。
-
Under low temperature condition, fertility restoring, anther developing normally, the tetrads formed after archesporical cell, sporogenous cells and microspore mother cell. Subsequently, microspores were free from the tetrad of fertile anther and formed mature pollen grains, tapetumof the fertile anthers began to disintegrate and disappear at last.
在低温处理条件下，育性恢复，花药发育正常，经过孢原细胞期、造孢细胞期、花粉母细胞期后，可以顺利形成四分体，可育花药的四分体可以释放出小孢子并发育为成熟的花粉粒，同时绒毡层细胞开始解体，最后消失。
-
No tapetal cells were formed or tapetam collapsed at very early stage in some anther chamber during the microsporogenesis; Pollen mother cells in another chamber were not developed and microspore vacuolized; Tapetum cells developed abnormally, giantized and crammed the anther chamber; Some tapetum cells developed normally, but PMCs developed abnomally, which deformed at sporogeneous stage, and then were abhensive each other and finally degenerated. Nearly no PMCs could complete the process of meiosis, and form the tetrad, leading to the failure of normal microspore development.
药室的绒毡层细胞不形成或提前解体；药室内的花粉母细胞不发育或小孢子液泡化；绒毡层细胞发育异常，出现巨型化而挤满整个药室；绒毡层细胞虽发育正常，但花粉母细胞发育异常，在造孢细胞时期即开始出现变形现象，随后发生粘连退化；绝大部分花粉母细胞不能完成正常的减数分裂过程形成四分体，导致小孢子退化。
