种子世界形形色色、大大小小,它们各就自己的生态位占据着整个世界,繁衍着地球上各种各样的生物。然而,统治世界的人类为了很好的生存,在开发利用种质资源的过程中,有意无意地破坏着生态平衡,使许多有价值的植物种失去了生态位,或者潜移,或者消失。为了繁荣世界,造福于子孙后代,科学地保存种质资源,尤其是优良基因,是非常必要的。现在,国际上很重视这项工作,许多国家建立了种质基因库(长期、中期、短期),并大量收集世界各地种质资源,主要以种子形式进行保存,为遗传育种学家提供遗传种质。妥善保存是种质资源管理工 The seed world is of all kinds, large and small, each occupying the entire world with its own niche and multiplying all kinds of creatures on the earth. However, in order to survive well, the mankind governing the world destroyed the ecological balance in the process of exploitation and utilization of germplasm, intentionally or unintentionally destroyed the ecological balance, caused many valuable plant species to lose their niche, or migrated or disappeared. In order to prosper the world and benefit future generations, it is necessary to preserve germplasm resources scientifically, especially the fine genes. At present, the international community attaches great importance to this work. Many countries have established germplasm banks (long-term, medium-term and short-term) and extensive collection of germplasm resources from all over the world, mainly in the form of seeds, providing genetics and breeding scholars with genetic species quality. Proper conservation is a germplasm resource management worker
