dc.description.abstractCork oak (Quercus suber L.) has a high ecological and social value and supplies raw materials for the cork industry, a relevant contributor to the economies of Mediterranean countries. Understanding the adaptation potential of cork oak populations to cope with different environmental conditions is a key issue of forest management, particularly for selecting the most adapted genetic material for (re)forestation and assuring the long-term sustainability of the cork industry. Intraspecific variation in fitness surrogate traits (survival, height and stem diameter) was investigated in thirty-five cork oak populations sampled from the entire range of the natural distribution of the species. The study was conducted in two provenance field trials, established in Portugal under different edaphoclimatic conditions. Each trial was surveyed at four tree ages (two ages, 11 and 14 years, were sampled simultaneously in both trials). The trial located at a lower altitude, which had higher mean winter and annual temperatures, exhibited higher growth and survival rates. In both trials, significant genetic variation among cork oak populations was observed for the analyzed traits and evaluated ages. Moroccan populations displayed a higher probability of survival and higher growth rates, while local populations exhibited an intermediate performance. Low to moderate correlations were found between the analyzed traits and the environmental variables of seed origin, suggesting that factors other than climate are likely to be relevant for cork oak adaptation. Moderate to high values of population mean-basis broad-sense heritability (H2≥0.44) and high genetic correlations between traits (0.88–0.95) were found for growth traits. This information is crucial for the establishment of a breeding program for the species. With this study, we have improved the knowledge regarding how cork oak performs for fitness surrogate traits in different environments.
dc.description.sponsorshipThe cork oak provenance field trials were funded by European (FAIR1-CT-95-0202) and national foundations (PBIC/AGR/2282/95, PAMAF 4027, PRAXIS/3/3.2/Flor/2110/95). The growth and survival measurements were assessed with the support of the European project: “CREOAK: Conservation and restoration of European cork OAK woodlands: a unique ecosystem in the balance” (QLK5–CT–2002–01594); and the “Repovoamento com sobreiro: Variabilidade genética e biologia da semente conservada (POCTI/41359/AGG/2001) national project. Research activities were also funded by Forest Research Centre (CEF), a research unit funded by Fundação para a Ciência e a Tecnologia I.P. (FCT), Portugal (UID/AGR/00239/2013). Teresa Sampaio was funded by the Portuguese Foundation for Science and Technology, Portugal through a doctoral grant under the SUSFOR Doctoral Programme (PD/ BD/52402/2013). The authors are thankful to Maria Carolina Varela who setting up the EU-concerted action on cork oak, FAIR I CT 95 0202 and to Carla Faria, Carla Leite and Regina Chambel that collaborated on the establishment of the Portuguese genetic trials. We also thanks to Ana Margarida Nunes, Lurdes Marçal, Madalena Silva, Maria João Lourenço and Sara Rocha for their support in field work.
