TAILIEUCHUNG - Analysis of dendrometric diversity among natural populations of cork oak (Quercus suber L.) from Morocco

The cork oak (Quercus suber L.) has been the focus of research dealing with the conservation and reforestation of this species due to its economic importance and the problem of deforestation affecting it. The genetic diversity of this tree species, its main aspect of adaptation, has not been sufficiently studied. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2016) 40: 127-135 © TÜBİTAK doi: Research Article Analysis of dendrometric diversity among natural populations of cork oak (Quercus suber L.) from Morocco 1 1, 2 1 3 Amal LAAKILI , Bouchra BELKADI *, Fatima GABOUN , Chaimaa YATRIB , Mohamed MAKHLOUFI , 3 1 4 1 Salwa EL ANTRY , Leila MEDRAOUI , Ahmed LAAMARTI , Abdelkarim FILALI-MALTOUF 1 Laboratory of Microbiology and Molecular Biology, Faculty of Sciences, Mohammed V University, Rabat, Morocco 2 Biotechnology Unit, National Institute for Agronomic Research (INRA), Rabat, Morocco 3 Department of Forestry and Forest Health, High Commission for Water, Forests, and Desertification Control (HCEFLCD), Forestry Research Centre (FRC), Agdal, Rabat, Morocco 4 Plant Biotechnology Team, Faculty of Sciences, Abdelmalek Essaadi University, Tetouan, Morocco Received: Accepted/Published Online: Final Version: Abstract: The cork oak (Quercus suber L.) has been the focus of research dealing with the conservation and reforestation of this species due to its economic importance and the problem of deforestation affecting it. The genetic diversity of this tree species, its main aspect of adaptation, has not been sufficiently studied. The Moroccan cork oak tree is found in the northern part of the country, where the fruits of the tree are soft corns. This forest tree species has undergone a strong decline due to many factors, including a significant loss of its biological diversity. While working within the national framework of protection and enhancement of this tree species, our research aimed to analyze and assess the phenotypic diversity of different provenances, using qualitative and quantitative dendrometric traits and geographical characteristics such as the total height of the tree (H), the height to the first branch (Hbr), girth (Gir), surface coefficient
