Effect of high CO2 and temperature in Botrytis storage rot and quality of kiwifruit.

Author(s) : CHEAH L. H., IRVING D. E., HUNT A. W.

Summary

High CO2 (60% CO2, 20% O2) at 30 or 40 deg C for 1, 3 or 5 days was tested in vitro and in vivo for the control of Botrytis storage rot of kiwifruit cv. Hayward. Spore germination and growth of B. cinerea were completely inhibited in culture by high CO2 at 40 deg C and partially suppressed at 30 deg C. Kiwifruits were inoculated with B. cinerea spores, exposed to high CO2 at 30 or 40 deg C, and stored in air at 0 deg C for up to 12 weeks after treatment. High CO2 at 40 deg C reduced disease incidence from 85% (air to 20 deg C) to about 50%, but exposure to CO2 at 40 deg C for longer than 1 day adversely affected fruit ripening.
