| 摘要: |
| 木兰属（Magnolia）是地球上最原始的植物属之一，由于人类的过度利用和环境的变化，野生资源急剧减少，部分种处于濒危状态，而植物组织培养技术是珍稀濒危物种繁殖、种群扩大及保护性开发利用的有效途径。近年来，开展木兰属植物组培快繁研究增多，取得长足发展，为生物多样性保护及繁殖提供了条件。文章概述了木兰属植物组培常用的外植体取材的部位与季节、基本培养基的选择、植物生长调节剂浓度的调配及培养的环境条件等，并探讨了研究过程存在的问题及研究展望。 |

| Abstract: |
| The Magnolia is one of the most primitive genus on the earth. Due to human overuse and environmental changes, wild resources have been drastically reduced and some species are endangered. The method of plant tissue culture is an effective way to reproduce, utilize and expand the population of rare and endangered species.In recent years, the research on Magnolia tissue culture and rapid propagation of plants has increased and significant development, which can provide conditions for biodiversity conservation and reproduction. This paper summarized the parts and seasons of explants commonly that used in tissue culture of Magnolia, the selection of basic medium, the concentration of plant growth regulators and the environmental conditions of culture. The problems in the research process and the research prospects were discussed. |
