“…Some of this material has been analysed previously (22 populations), and the results published in DumolinLapègue et al (1997). Material from a Q. robur provenance test was used in addition to direct sampling in Croatia (16 of the 38 populations; Gračan, 1993). In general, the aim of the sampling was the collection of all species of the Robur group locally present, however, in Croatia, special emphasis was given to Q. robur.…”

“…The Slavonian oak (Q. robur ssp. slavonica) can be distinguished by its exceptionally straight stem, its relatively regular crown and upward pointing branches and both early-and late-flushing characters (Gračan, 1993;Bordács, 1994). The related taxon Q. pedunculiflora has been previously considered as a subspecies of Q. robur (see reference in Bussoti and Grossoni, 1997).…”

A total of 1113 oak trees from 222 populations originating from eight countries (Austria, Bosnia-Herzegovina, Croatia, Hungary, Romania, Slovakia, Slovenia, Yugoslavia) were sampled in natural populations or in provenance tests. The sampled trees belong to four different species (Quercus robur, Quercus petraea, Quercus pubescens, Quercus frainetto) and to several putative subspecies. Variation at four chloroplast DNA (cpDNA) fragments was studied using restriction enzymes, resulting in the detection of 12 haplotypes. One haplotype was present in 36% of the trees, and six were found in 6-17% of the trees. The haplotypes are shared extensively between species and subspecies. They belong to three different lineages (A, C and E) and are phylogeographically structured in the region investigated. Haplotypes of lineage E dominate to the east of the Carpathian mountains in Romania, whereas the Carpathian Basin seems to have been colonised along several different colonisation routes, from the Balkan peninsula but also from Italy. The data support the possible role of climatic instability during the late glacial period in shaping this complex geographic structure. The presence of several secondary refugia could be inferred in the region, which have played a major role in the second step of recolonisation, at the onset of the Holocene period. #

Prze¿ywalnooeae i wysokooeae dêbu szypu³kowego (Quercus robur l.) testowanego na powierzchni dooewiadczalnej "Chrostowa I" w Nadleoenictwie BrzeskoSurvival and height of pedunculate oak (Quercus robur L.) in Chrostowa I experimental trial in Brzesko Forest District Abstract. The paper presents the results of a provenance-×-family experiment measuring traits in the progeny of 4 provenances and 25 families of Quercus robur. The height and survival of trees were monitored at an experimental site located in the Brzesko Forest District in the Wisnickie foothills. The heritability of height was estimated from data collected during the years 1995-2007. The survival rate of young seedlings from lowland provenances was high, and this suggests that these populations should be used for oak plantations in the Carpathians. At 15 years old, the progeny of the Tronçais provenance from the Massif Central, France, is performing very well under the conditions of the trial in the Wisnickie foothills, maintaining comparable survival and significantly superior growth to the Polish provenances. However, its superiority over the best Polish provenance, Zaporowo, has been steadily decreasing with age. Growth differed significantly among provenance populations in each year of measurement, and the effect of family within provenance has tended to increase over time. The provenance heritability of height (0.53 to 0.91) is higher than the family and individual heritability. Up to the age of 11 this value increased with age, however from age 11-15 it decreased slightly. By contrast, the family and individual heritabilities had decreased to zero by the year 2001 (age 9), but have since started to rise again. This reversal can be attributed to increased differentiation between the progenies of individual trees within provenances.
