tConventional (CG) and organically grown (OG) ‘Hayward’ kiwi fruits were submitted to ethylene treatment for 24 h, followed by storage at 20◦C for 10 days. Radical scavenging assays, UV spectrometry,fluorometry and chemometrical processing were used to determine the main kiwi fruits’ compounds. Firmness gradually decreased the longer they were stored, regardless of cultivation type. The rate of softening was slightly higher in OG than in CG fruits.
