Responses of "Kent" and "Tommy Atkins" mangoes to reduced O2 and elevated CO2.

Author(s) : BENDER R. J., BRECHT J. K., CAMPBELL C. A.

Summary

Marine shipments of mangoes to export markets requires a 2-to 3-week transit time. Mango tolerance of low O2 and high CO2 concentrations over this time period were evaluated. Mature, unripe mangoes were stored for 21 days at 12 deg C in air or 25, 45, 50 or 70% CO2 plus either 3 or 20.8% O2 in N2 or the same CO2 concentrations mixed with air. The fruits were then transferred to air at 20 deg C for 5 days. 50 and 70% CO2 resulted in the highest ethanol production rates, while the 3% O2 concentration seemed to have little effect on ethanol production of either cultivar. After transferring the mangoes from air at 12 to 20 deg C, ethanol production rates in storage were low and increased significantly along with respiration rates. Symptoms of CO2 injury appeared in mangoes exposed to 50 and 70% CO2.
