摘要
进入21世纪,种质资源保存越来越被广泛应用和重视,其广泛定义被描述为“人类利用生物圈(即全部生物)的管理,使其能给当代人最大的持久利益,同时保持它的潜力以满足后代人的需要和愿望”。从狭义讲,保存主要采用自然(原生境保存in situ conservation)和基因库(非原生境保存ex situ conserva-tion)相结合的方法对种植资源进行保存。沙棘属有6个种12个亚种,其中6个种6个亚种分布在我国,其资源量占沙棘总资源量的90％以上。因此中国承担着沙棘种质资源保存和研究的重大责任和义务。为此,对沙棘属植物进行系统的收集、保存、研究和管理是实现沙棘资源可持续利用和开发的必然之路。
Germ plasma resources conservation has been paid a more and more great attention in world wide in the 21th century. It is described in wide-ranging as “the management for human beings to uti-lize the whole biology resources, and to make it sever for the present with highest benefit and at the same time to conserve its potential to meet the late generation need” . It can also be defied in narrow-ranging as the conservation to natural plants and genes. There are 6 species and 9 sub-species within seabuckthorn family, among which 6 species and 6 sub-species are distributed in China, where ac-count about 90% of seabuckthorn resources in the world. China is not only proud of its rich seabuck-thorn germ plasmas resources, and also with high responsibility and obligation to develop their re-search and conservation. It is so important to do the collection, conservation and scientific research, management of seabuckthorn family plants for its sustainable utilization.
