چکیده
Exploiting biodiversity must be considered today an effective strategy to improve the sustainability of olive production systems. The evaluation local cultivars, based on their vegetative and fruiting traits, along with analysis product quality, may contribute significantly development diffusion new olive-growing aim this study was evaluate growth, productivity, oil quality three Sicilian cultivars different vigor/growth habit grown in four combinations training form planting density. ‘Abunara’, ‘Calatina’, ‘Nocellara del Belice’ trees were planted intensive systems: 2 × 5 m trained central leader (CLx2), 3 free palmette (FPx3), 4 small globe vase (GVx4), poly-conic (PVx5) evaluated for seven years. Planting systems low-density showed faster growth (trunk cross section area canopy volume) than high-density High-density had higher yield per hectare but lower tree ‘Calatina’ least vigorous most productive cultivar. ‘Abunara’ ‘Nocellara’ relatively suffered tight spacings Yield efficiency generally high it increase time under GVx4 PVx5 Fruit highest Oil ‘Calatina’. In terms produced oils oleic acid content ‘Nocellara’. Generally, has characteristics considerable interest, which, combined low volume vigor, make suitable pedestrian orchards levels harvest pruning mechanization using strategies machines. Overall, management flexibility, these can industry even sloping, dry areas Mediterranean.
