Towards molecular tools for management of oak forests : genetic studies on indigenous Quercus robur L., and Q. petraea (Matt.) Liebl. populations
This thesis describes the genetic composition of indigenous oak populations in the Netherlands using two different molecular marker techniques, AFLP and microsatellites. No diagnostic AFLP marker was found that could differentiate between Q. robur and Q. petraea, but five species-indicative AFLP markers were observed. This indicates that the two oak species are closely related. AFLP and microsatellite analysis of an ancient woodland described large Q. robur and Q. petraea clones with diameters up to 5.8 m. Such large clones are an indication for the old age of such woodlands that have a history of coppicing and grazing. As indigenous oak populations in the Netherlands suffered from large scale deforestation and have been coppiced and grazed for centuries, it was expected that the genetic variation of such populations would be low. However, the genetic variation observed for two indigenous Q. robur populations was as high as for unmanaged French and German Q. robur populations. Molecular markers that are closely linked to quantitative trait loci (QTLs) controlling eco-physiological and morphological traits can be used in ecology and forestry. Therefore, a genetic linkage map of Q. robur was constructed and QTLs controlling eco-physiological and morphological traits were located.
