Morphological and genetic variability of pedunculate oak (Quercus robur L.) populations in SloveniaBatič, Franc (Avtor) Sinkovič, Tomaž (Avtor) Javornik, Branka (Avtor) pedunculate oakmorphologymultivariate analysisRAPD markersgenetic polymorphismnatural hybridisationThe article presents a taxonomic study carried out in three pedunculate oak populations in Slovenia by leaf morphometry and by DNA analysis with RAPD markers. About one hundred leaves were sampled from five trees from three seminatural pedunculate oak stands in the Sub-pannonian vegetation region of Slovenia. Samples were collected from the well lit upper part of the tree crowns, and only leaves from short twigs were analysed. Leaf samples were herbarised, and measured and assessed in the laboratory. Leaf dimension (lamina length and width, petiole length, number of lobe pairs) were measured and characters like type of leaf pubescence and leaf lamina base type were assessed. Analyse of leaf morphometry showed that ali sampled trees belonged to the Quercus robur L. species. Nevertheless, on some trees, leaves also showed characters typical of sessile oak (Quercus petraea /Matt./ Leibl.), especially the leaf lamina base typ,3 and number of lobe pairs. Other parameters analysed were within the variation of pedunculate oak. More populations of both oak species should be analysed, especially when growing together, in order to obtain reliable data for taxonomic studies of oak hybrids and population genetic diversity by means of classic leaf and acorn morphometry and molecular markers. 19952015-07-10 21:33:30Neznano69640sl
