Resumen: BACKGROUND Super-intensive cultivation facilitates olive mechanized harvesting, allowing substantial savings in the production cost of virgin olive oil (VOO). However, the number of varieties adapted to this type of cultivation is small. This study explores the impact that harvesting with a grape straddle harvester of ‘Manzanilla de Sevilla’ and ‘Manzanilla Cacereña’ olives grown in super-intensive cultivation has on the physiology of the fruit and the quality of the oil subsequently extracted. RESULTS For both cultivars, fruits harvested mechanically showed higher respiration and ethylene production and lower firmness than fruits harvested by hand. Their oils exhibited lower phenol contents, lower oxidative stability and lower presence of positive sensory attributes. However, in these oils the values of parameters used to assess the level of quality of VOO remained within the limits required for the best commercial category. CONCLUSION Mechanical harvesting of ‘Manzanilla de Sevilla’...
