中文摘要：
本文对植物迁地保护,特别是种质资源保护的研究背景、科学问题、行动计划和保护策略进行了评述,重点讨论了种子库在保护植物多样性中面临的挑战和重要科学问题,特别是种子活力、种子寿命和超低温保存等问题。大量的实例和数据表明,种子库作为植物多样性保护的重要手段之一,其在资金投入、保存时间和保存效率方面远远高于就地保护和其它的迁地保护方法。
英文摘要：
This paper discusses backgrounds,scientific issues,action plans and strategies in relation to ex situ plant conservation,particularly germplasm banking as an insurance policy against extinction .Germplasm banking approach enables the conservation of thousands of wild species of plants.The assumptions,costs,risks and scientific challenges associated with ex situ plant conservation depend on the species,the methods employed and the desired storage time.Relatively widespread evidence of less than expected longevity at conventional seed bank temperatures,innovations in the cryopreservation of recalcitrant-seeded species and economic comparators provide compelling evidence that ultra-cold storage should be adopted for the long-term conservation of plants.
