摘要
结合云南自然地理和森林树种植物区系特点,就制订其森林树种种质资源保存策略提出如下建议:开展3种保存方式及建立在分子标记基础之上的样本技术研究;分别气候带和地域实施有侧重的原地和迁地保存,分期建立9个迁地保存中心;配合重大林业生态工程,营建迁地保存林及提供优良种质;在云南"中华生物谷"项目中建立专门的种质低温保存库。
Aimed at drafting the germplasm resources conservation strategy of Yunnan forest tree species, some suggestions are made on the basis of the characteristics of the physiography and the flora of forest tree species in Yunnan. They are:(1) The researches are made on the 3 conservation methods of germplasm resources and the sampling strategy based on molecular markers; (2) Conservation in situ and ex situ related to the climatic zones and regions must be carried out with particular emphasis, and 9 centers of conservation ex situ are set up by stages; (3) Forests of conservation ex situ can be planted in the areas of major forestry projects, and some excellent germplasms chosen for the projects; (4) A special conversation bank in low temperature is built for forest tree species under the project of Chinese Biovalley.
