巴西植物遗传资源保护与对外交流管理

巴西拥有高等植物55000种,居世界第一。植被分为6个区系,即亚马逊雨林、塞拉多(Cerrado)稀树草原、卡廷加(Caatinga)旱生植被、大西洋雨林、南方森林草原和潘塔纳尔(Pantanal)湿地植被。已建立554个原生境保护区和126个基因库,保存植物遗传资源25万份。对外交流由巴西农业科学院(EMBRAPA)遗传资源与生物技术中心(CENARGEN)统一管理。

Plant Genetic Resources Conservation and International Exchange Management in Brazil

With nearly 55000 native higher plant species,Brazil is considered the country with the greatest biodiversity on the planet.These species are distributed over six distinct biomes,which include Amazon forest,Cerrado,Caatinga,Atlantic forest,Meridional forests and grasslands,and the Pantanal.A national system for plant genetic resources conservation is established over the country,which include 554 reservations for in situ conservation and 126 genebanks for ex situ conservation.About 250 000 accessions of plant germplasm have been stored.The Centre for Genetic Resources and Biotechnology(CENARGEN)and Brazilian Agricultural Research Corporation(EMBRAPA) are in charge of the management of international exchange for genetic resources.
