Resumen: Fatty acid (FA) metabolism, particularly changes in unsaturation levels in response to low-temperature stress, has been suggested to play a key role in fruit tolerance to postharvest chilling injury (CI), a major physiological disorder in citrus. Although preharvest environmental conditions are known to influence CI incidence during cold storage, the relationship between preharvest variability, FA metabolism and CI remain still unclear. Therefore, in this study we investigated FA metabolism in the peel of three citrus genotypes harvested from locations with contrasting agroclimatic conditions. Fruit of Tango and Nadorcott mandarins and Valencia orange exposed in the field to a higher number of hours of cold (
