In Colombia, coffee harvesting results from the asynchronous fruit ripening throughout the year. To reduce the number of harvesting rounds, it is necessary to modify the natural ripening process by using ripening retardants, such as ethylene inhibitors applied during the pre-harvest stage. The objective of this study was to evaluate ethylene inhibition in coffee fruits through the application of salicylic acid (SA). The experiment was conducted using fruits at four ripening stages: green, turning, ripe, and overripe, collected from two 36-month-old plots of Castillo® variety located at the Naranjal Experimental Station– Cenicafé. Salicylic acid at 1 mM was used as treatment, along with an untreated control without inhibitor application. In control fruits, ethylene emission increased from the green to the ripe stage, with emission rates ranging from 1.1 µL kg-1 h-1 to 2.2 µL kg-1 h-1. Application of 1 mM SA reduced ethylene production, with an average inhibition between 10% and 15%. Green fruits showed the lowest inhibition (10%), followed by overripe (11%), turning (12%), and ripe fruits (15%), the latter being the most affected by the treatment. These results suggest that, although SA acts as an ethylene modulator, its capacity to inhibit ethylene production in coffee fruits is limited.
