Johann Heinrich von Thünen-Institut, Federal Research Institute for Rural Areas, Forestry and Fisheries, Institute of Forest Genetics

The Institute carries out research on genetics of indigenous and exotic tree and shrub species. The studies help to elaborate recommendations for national and international laws, conventions and strategies in the area of forest reproductive material, biological diversity, control of origin for timber and forest reproductive material, conservation of forest genetic resources, genetic engineering, adaptation to climate change and optimisation of biomass production.

Fields of research:



·         Tissue culture laboratories and cultivation rooms

·         Microscopy room

·         S1-laboratories and cultivation rooms

·         Laboratories for genetic analyses

·         Arboretum

·         Field trials

·         Greenhouses
