摘  要:
黄波罗是中国东北红松阔叶林中的重要伴生树种。本文报导了黄波罗的种子扩散、休眠、种子库和天然更新。黄波罗种子扩散主要靠鸟类和重力。假种皮可能延长种子的寿命。在天然次生林中,种子库贮存量可达750 000粒/ha,其天然更新与干扰有关,而以重干扰生境上种子发芽最好。

摘  要:
Amur corktree (Phellodendron amurense Rupr.) is one of the important accompanying species of korean pine (Pinus koraiensis) broadleaved forest in northeast China. This paper reports on the seed dispersal, dormancy, seedbank and regeneration of amur corktree. Seeds of amur corktree are dispersal mainly by the aid of birds and gravity. Aril of the seeds may increase the seed longevity. In natural secondary forests, the amount of storage of the seedbank may reach 750000 grains per hectare. Regeneration was correlated with disturbance, and was best under intensive disturbance.
