CARBON DIOXIDE REQUIREMENTS OF APPLES IN CA 



William J. Lord 

 Department of Plant S- Soil Sciences 



The placement of lime in CA rooms to supplement caustic or water 

 scrubbing is being practiced by many storage operators. Since tlie pos- 

 sibility of maintaining extremely low COn levels (less than 2%) exists, 

 growers have asked whether these levels would be detrimental to the 

 keepability of apples. Recently, we came across a report by S. W. 

 Popritt in the Summary Report of Research 1952, Summerland, B. C, and 

 published in September, 1964, which thi^ows some light on the subject. 



Porritt reports that near 0% COp with 3% Op results in more rapid 

 softening, greater rate of acid loss and considerably more physiologi- 

 cal disorders than atmospheres with 2% or more CO2. "Flesh browning of 

 Newtown, Mcintosh, and Spartan apples, skin bronzing, probably allied 

 with scald, browning of vascular bundles in Spartan, and a general in- 

 crease of mold growth have been consistently associated with near 0% CO2 

 atmospheres . " 



Data of this type indicate that growers should strive to maintain 

 the CO2 level in Mcintosh rooms at 2 -3% for the first M- - 6 weeks and 

 M-.O - 5.S% thereafter. The Indiscriminate use of lime withing CA rooms 

 should be avoided if one is to be sure of CO2 levels above 2% through- 

 out the storage period.
