以龙芽楤木种子为对象，研究不同低温层积时间、冷冻处理对发芽力的影响，结果表明：龙芽楤木种子经日变温层积处理后，低温处理120 d左右时，发芽率、发芽势最高；已解除休眠的龙芽楤木种子经冷冻处理后进入二次休眠状态，经90 d左右的低温层积处理可解除休眠，与二次休眠前相比较其发芽率略有降低而发芽势则有所提高。

The effect of different temperature layers time and freezing treatment on germination force by choosing the seed of Aralia elata as object.The results showed that the germination rate and germination potential of the seed of Aralia elata were maximum after day variable temperature stratification and low temperature treatment for 120d.The seed of Aralia elata which had broken dormancy fell into the second hibernation after freezing treatment.It can break dormancy through low temperature stratification for 90d.Compared with the second dormancy, the germination rate decreased slightly while germi-nation potential increased.
