An Agronomic Approach to Pine Nut Production by Grafting Stone Pine on Two Rootstocks

Stone pine (Pinus pinea) grows in natural stands within the Mediterranean basin and its nut is highly appreciated for nutritional profile. Nevertheless, a decline this species due to biotic abiotic damages currently being clearly observed. This situation has led development as crop, try save production obtain regular harvests over years. Under agronomic scenario, aim of work was compare behavior stone grafted onto two rootstocks, P. pinea (PP) halepensis (PH), by evaluating cone productivity, tree growth response, mast seeding patterns composition. The field test composed 14 PH PP, randomly distributed into groups 4–5 trees/rootstock. Data were from seven productive growing seasons. results show higher ripe on PP rather than PH, although productivity (cones/m2 canopy) similar. Any effect rootstock observed pattern weight cones, while composition showed differences fatty acids content. global quality similar PP.
