摘要
光皮桦一年生播种苗营养器官的解剖结构显示，根、茎、叶各器官的输导组织较为发达，输导效率高；形成层细胞分裂次数多，分裂速度快，形成的次生木质部径向厚度大。其解剖构造适应于苗木的迅速生长。
This paper studies the morphological anatomy of annual seedlings of Betula luminifera. The results show that highly advanced conducting tissues and high radial thickness of secondaryxylem to mere times and high speed of cambium fission are important anatomic characteristics of Bethe luminifera.
