Effect of Carbon Dioxide on Activity of Succinic Dehydrogenase in ‘Bartlett’ Pears During Cold Storage1

Abstract
‘Bartlett’ pears (Pyrus communis L.) were kept in cold storage in air, and at CO2 concentrations of 5, 10, 15, and 20%. The mitochondrial fraction from the fruit pulp was extracted periodically, made into acetone powder and assayed for activity of succinic dehydrogenase. Progressive decreases in activity of the enzyme were observed with increases in CO2 concentration in the storage atmosphere.
