Water stress effect on hydraulic architecture, biomass partitioning, and gas exchange of four different olive cultivars.

L. is considered a very resilient species to water deficits. Climate change, characterized by warmer summers and drier winters, may challenge even this adaptable species, potentially making once-suitable areas less viable for cultivation.

Growth, yield and oil quality of adult pedestrian olive orchards grown at four different planting systems.

This study evaluated growth, yield and olive oil quality of mature pedestrian olive orchards. Trees of three Sicilian cultivars Calatina, Nocellara del Belice and Abunara were planted at four combinations of planting densities and training forms. Trees at 2 × 5 m were trained to central leader (CLx2), those at 3 × 5 m to free palmette (FPx3), those at 4 x 5 to globe vase (GVx4), and those at 5 x 5 to poly-conic vase (PVx5).

NGS transcriptomic analysis uncovers the possible resistance mechanisms of olive to leaf spot infection.

is a dangerous obligate fungal pathogen of olive, feared in the Mediterranean countries, causing or , which can lead to a serious yield loss of approximately 20% or higher depending on climatic conditions. Coping with this disease is much more problematic for organic farms. To date, knowledge on the genetic control of possible mechanisms of resistance/low susceptibility is quite limited.
