Abstract: In order to understand the parasitic property of Cynomorium songaricum, the dormancy and germination properties of C. songaricum seeds are researched. The seed germination was promoted with both physical and chemical ways. The results show that the C. songaricum seeds are small, and the embryo of matured seeds develops incompletely and at the globular proembryo stage all the time before and after germination. The results testified that the germination of C. songaricum seeds need a certain stimulating signal form the host roots; exogenous GA3 and ethylene solution have a function of breaking the dormancy of C. songaricum seeds.

Key words: Cynomorium songaricum, parasitic plant, seed, germination property, dormancy
