Respiratory activity and mitochondrial oxidative capacity of bell pepper fruit following storage under low-oxygen atmosphere.

Bell pepper (Capsicum annuum L.,var.'Jupiter') fruit stored in 1.5%, 5%, or 10% O2 or in air at 20C for 24 hours were compared to determine the residual effect of low-O2 storage on respiration after transfer to air. The lowest concentration (1.5%) exerted the greatest residual effect on bell pepper fruit CO2 production and O2 uptake. No ethanol was detected in the headspace gas of fruit stored in 1.5% O2 Carbon dioxide production continued to be suppressed for approximately 24 hours after transfer from 1.5% air. Exposure to 5% O2 for 24 hours resulted in less suppression of production and C02 uptake upon transfer to air, while exerted no residual effect. Extending the storage period in 1.5% O2 to 72 hours extended the residual effect from 24 to 48 hours. Ethylene production was not affected by storage in 1.5% or 4% O2 for 24 or 72 hours. The residual effect exhibited in whole fruit was not apparent in mitochondria isolated from bell pepper stored in 1.5% or 4% O2.
