Ethylene production was measured according to the method by Han et al. with some modifications [58]. Five fruits were enclosed in a 3.6 L airtight vessel for 1 h at 25 °C, and 1 mL gas sample was collected with a syringe. This gas sample was injected into GC-14A flame ionization detector gas chromatograph (Shimadzu, Kyoto, Japan) to determine ethylene concentration. The ethylene production rate was expressed as µL·kg−1·h−1. Three biological replicates were maintained.
