Kinship Analysis and Pedigree Reconstruction of a Natural Regenerated Cork Oak ...
Mendes, Bruna; Sampaio, Teresa; Antunes, Marta; Magalhães, Hugo; Costa e Silva, Filipe; Borges, Carla; Simões, Fernanda; Usié, AnaCork oak (Quercus suber L.) is a valuable forest species in the western Mediterranean Basin due to its ecological value and the production of cork (a renewable natural material). Cork quality depends on the genetic background and cork oak environment, which has long been recognized. As no cork oak genetic trials with pedigree information were available, the inference of the genetic relatedness between individua...

Genetic variation among and within Quercus suber L. populations in survival, gr...
Sampaio, Teresa; Gonçalves, Elsa; Faria, Carla; Almeida, M.HelenaCork oak is an important forest tree species in the Western Mediterranean region due to the high economic value of its renewable cork and its ecological and social services. However, studies regarding the genetic variation within cork oak populations are scarce, and this gap of knowledge is contributing to the delay of the set-up of a breeding and conservation strategy for the species. In this study, the geneti...

Almeida, Maria Helena; Aranda, Ismael; Chambel, Maria Regina; Silva, F. Costa e; Dettori, Sandro; Faria, Carla Maria Gomes MarquesThe European Academies' Science Advisory Council (2017) reports that the Mediterranean forest is already being affected by climate change (IPCC, 2014) and cork oak woodlands are particularly vulnerable to high-end climate scenarios that go above the Paris Agreement 2° C increase in temperature. Since longer, more frequent, and more intense drought periods are expected, stress caused by the expansion of arid and...
Seed origin drives differences in survival and growth traits of cork oak (Querc...
Sampaio, Teresa; Gonçalves, Elsa; Patrício, Maria Sameiro; Cota, Tânia M.; Almeida, Maria HelenaCork 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 ...
Provenance behavior in the cork-oak International network trials fair 202
Varela, Maria Carolina; Sampaio, Teresa; Filigheddu, Maria Rosaria; Zucca, G.M.; Patrício, Maria Sameiro; Almeida, Maria HelenaThe international network of provenance trials in cork-oak was established as a result of the EU Concerted Action FAIR 202, 1995-2000. 34 provenances were selected in the natural range of cork oak and trials were established in 1996/97 in France, Italy, Portugal, Tunisia and Spain. This study compares the behavior of provenances in the trials of Grighini (Sardinia), Monte Fava and Quinta da Nogueira (Portugal),...

Sampaio, Teresa; Silva, João Costa e; Sanchez, Leopoldo; Patrício, Maria Sameiro; Almeida, Maria HelenaIn the face of climate change, understanding the adaptation potential of woody species to cope with difíerent environmental stress events (e.g., drought, frost, pests and diseases) is required to develop sustainable forest management practices. In this context, a key issue when pursuing reforestation actions is to know whefher current locally adapted provenances will still show good survivat and growth under ch...
Geographic variation in cork oak and its implications for expected impacts of c...
Rodrigues, Ana; Sampaio, Teresa; Silva, João Costa e; Patrício, Maria Sameiro; Silva, Filipe Costa e; Faria, Carla Maria Gomes MarquesCork oak (Quercus suber L.) is a protected tree species in Portugal, being also the source of raw material for the cork industry, a major player in Portuguese economy (representing 3% of GDP in 2010). The future climatic scenarios for Portugal point to an increase in average summer temperatures from 0.3 to 0.7ºC between 2016 and 2035, and up to 4.6ºC until 2100. In addition, precipitation estimates suggest a re...

Varela, Maria Carolina; Tessier, Charles; Ladier, Jean; Dettori, Sandro; Filigheddu, Maria Rosaria; Bellarosa, Rosanna; Vessella, FedericoThe international network of provenance and progeny trials was established in 1998 benefiting from homogeneous plant raising and standardize experimental design. The trials include 34 provenances that are being characterised by several teams. France 2008. Provenance PT 23 and PT+ES 25 had the lowest survival rate. In 2008 the mean height was 48.73 cm and the form keeps plagiotropic. Italy- Sardinia, 2010 - The ...
