Sažetak
The European black poplar (Populus nigra L.) is a pioneer tree of alluvial forests (the priority habitate type 91E0*) and one of the most threatened indigenous tree species in Europe. We analysed the genetic diversity of 10 black poplar populations along the main river systems across Slovenia and Croatia (rivers Soca, Sava, Drava and Mura) by using six microsatellite loci (WPMS16, WPMS20, WPMS14, PMGC14, WPMS09, WPMS18) and combined analysis with Austrian data for rivers Mura and Danube with same microsatellites. Eleven common cultivated clones of Populus x canadensis were included in order to assess the level of introgression of genes of the American Eastern cottonwood, P. deltoides, into the gene pool of native black poplar. The results of this study indicate that the gene pool of remaining Populus nigra populations maintains high genetic connectivity across three European countries, even if fragmented today. In natural populations the introgression of genes of Populus deltoides was very low. The obtained results are further compared with current status of Populus nigra populations in Central Europe and discussed in view of nature habitat conservation and its protection at regional and national level.
