| | Résumé : | The spatial genetic differentiation among European beech stands in western Germany was analysed by a new method. The genetic structure at 8 enzyme gene loci of lOO sarnpled populations was used as data base. The data represent authors' own results and published data from 8 different studies. For 10 geographic distance classes [h] from 0 to 500 km, the average genetic distance J(h between the populations for each single gene locus, a gene-pool distance J(hk) and the semivariances ,(hk) of genetic diversity Ugam were computed. Significant deviation from random spatial genetic structure was teste by permutation analysis. ln many cases (Lap-B, Mdh-B, Mdh-C and 6Pgdh-C) the mean genetic distance h J between stands with spatial distance up to 200 km was significantly smaller and the genetic distance between stands with geographic distances of 200 and 400 km was significantly greater than expected for random spatial genetic structure. Similar tendencies were
found for the gene-pool distance and the semivariances y(hk) of diversity. Kriging, as a method for spatial interpolation, was used to draw synthetic maps of the spatial patterns of allelic frequencies and genetic diversity. The influence of postglacial recolonisation and regeneration with foreign seed material on the spatial genetic patterns are discussed. | | Type de document : | Tiré à part | | Permalien de la notice : | https://infodoc.agroparistech.fr/index.php?lvl=notice_display&id=150493 |
