WebbIn ten cultivars of apple fruit, ethylene production expressed in µl/kg/h was determined. The cultivar Resista exhibited a higher ethylene production and can be differentiated from other cultivars. The production ranged from 4.2 ± 0.58 µl/kg/h in the case of Meteor cv. up to 131.6 ± 5.5 µl/kg/h in Resista cv.
