CO2 in apple and pear storage – Adjunct Professor Robert Prange, Faculty of Agriculture, Dalhousie University, Canada
In the absence of a reliable method to determine the acceptable CO2 concentration for long-term CA storage, I have examined the utility of the CO2/O2 ratio, using a database of commercial storage recommendations from around the world that I have compiled. In this approach, the maximum CO2 concentration is chosen in proportion to the O2 concentration applied. Using the information from the database, I have classified the major apple and pear cultivars into 7 CO2/O2 ratio categories and identified the possible influence of cultivar pedigree, storage temperature and storage O2 on the CO2/O2 ratio. A research methodology is proposed to determine a cultivar’s optimum CO2/O2 ratio at a chosen temperature and O2 concentration.
