Artificial regeneration of cork oak (Quercus suber L.) in experimental plots, in the Jijel region (East-Algerian coast)


Abstract: Cork oak natural regeneration in Algeria is very problematic. To perform artificialregeneration, the most efficient techniques must be adopted. We studied the influence of variousparameters (culture substrate, planting pot size and rootage by bands on the recovery and growthof cork-oak seedlings. Results showed that: i) substrates made from local materials (peat andforest humus) produced stronger seedlings than those made from imported peat; ii) larger pots(60cm in ridge size) offered to seedlings better growth and restart conditions than smaller ones(40-50cm in ridge size); iii) rootage by bands seemed to improve the recovery and growth of thecork-oak seedlings.
