| 摘 要： | 对秃叶黄皮树和黄檗种子进行了种子形态、种皮透水性、发芽率等方面的比较研究。结果表明：种皮对秃叶黄皮树和黄檗种子的透水性有较大影响，前者透水性较后者好；秃叶黄皮树种子的田间发芽率为68．7％，极显著高于黄檗的36．3％；秃叶黄皮树种子和黄檗种子具有休眠特性，且秃叶黄皮树种子的休眠较黄檗浅，经过低温层积后两种种子的萌发率都有所提高。

| Abstract: | The characteristics of seed germination, such as seed morphology, water permeability of seed capsule and germination ratio, were compared between Phellodendron chinense Schoneid. var. glabriusculum Schoneid and P. amurense Rupr. in this paper . The results indicated that the seed capsule has obvious effect on water permeability for both species, and the former had better water permeability. Similarly, The field germination rate of former specie was 68.7% , significantly higher than latter specie (36. 3% ). The seed of both species has the characteristic of dormancy, with deeper dormancy in P. amurense Rupr. However, seed dormancy of both species could be broken by low temperature stratification. |
