The genetic structures of a range of Douglas-fir provenance collections after planting in different European countries, assessed with two biochemical marker systems
I Forrest, H Tabbener, J Cottrell, T Connolly - Biochemical systematics and …, 2001 - Elsevier
Genetic diversities of Douglas-fir provenance trials planted on several European sites were
compared using both isozyme and terpene markers. A principal coordinate analysis based
on similarity coefficients calculated from isozyme data indicated that, with the exception of
two populations, differences between populations were small. There were no consistent
trends in the variation in allele frequencies between populations. Most populations
contained an excess of homozygotes, perhaps due to high selection pressure. Terpene …
