Abstract:
In order to protect the small populations of Bretschneidera sinensis better,the causes of Bretschneidera sinensis endangered from the angle of ecological and genetic diversity were analyzed,and a method for germplasm conservation of Bretschneidera sinensis was further put forward.The difficulties of seedling recruitment and reducing of genetic diversity were the main cause of Bretschneidera sinensis endangered,improving the seedling survival rate and the level of genetic diversity could preserve the germplasm resources of Bretschneidera sinensis effectively.
