Abstract
Objective Looking into the causes of self-regeneration obstacle of the wild Phellodendron amurense population in order to provide the reference for the sutdy of the germination mechanism. MethodsThe germination and seedling growth were observed by taking cabbage, wheat, and P. amurense as the tested objects and the sarcocarp and seed of P. amurense were extracted by alcohol and ethyl ether. Results The extract in sarcocarp and seed of P. amurense could decrease the germination rate of cabbage, wheat, and P. amurense seed, also inhibit the seedling growth in different levels. The inhibitory effect was getting stronger and stronger following the concentration increased. The ethyl ether extract showed the best inhibitory effect, while the water extract had no significant effect. The embryo, emdosperm, and cotyledon of P. amurense were extracted by distilled water, and among them the cotyledon had the strongest inhibition. Conclusion There are some substances with the better inhibitory effect in the sarcocarp and seed of P. amurense, which can inhibit the growth of itself and other plants significantly. The substance with the inhibitory effect exits mainly in cotyledon.
