- 摘要:
- 为了更好地保护极小种群伯乐树,从其生态习性和遗传多样性的角度分析了伯乐树濒临灭绝的原因,并提出了伯乐树种质资源保存的方法;指出幼苗更新困难和遗传多样性降低是造成伯乐树濒临灭绝的主要原因,通过提高幼苗成活率和遗传多样性水平可有效对伯乐树种质资源进行保存。
- 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.
