植物种质资源超低温保存现状及其研究进展

Progress on Cryopreservation State and Research of Plant Germplasm Resources

根据联合国粮农组织2010年发布的世界各国的《第二份世界粮食和农业植物遗传资源现状报告》以及有关国际会议和相关文献资料,从超低温保存材料类型、基本程序、方法技术、理论基础、影响因素、保存费用、保存策略和保存现状、实际应用等方面综述了全球植物种质资源超低温保存现状及其研究进展,展望了植物种质资源超低温保存技术的应用前景,旨在加强非正常型种子植物种质资源的安全长期保存。文章最后分析了我国存在的差距,提出了今后努力方向和发展的建议。

The current article was a synthesis of progress on cryopreservation state and research of plant germplasm resources in the world,based on the Second Report of the State of the World＇s Plant Genetic Resources for Food and Agriculture, international conferences, and other literatures. The contents covered material types, basic procedures, methods and techniques,theoretical basis,influence factors, costs, strategy, and practical application in the cryopreservation of plant germplasm resources. It also identified the gaps and put forward striving direction and suggestions for strengthening the safety and long-term cryopreservation of non-orthodox seed plant germplasm resources in China.
