Effects of Elevated CO₂ Concentrations on Glycolysis in Intact `Bartlett' Pear Fruit

Department of Pomology, University of California, Davis California 95616

Mature intact `Bartlett' pear fruit (Pyrus communis L.) were stored under a continuous flow of air or air + 10% CO₂ for 4 days at 20°C. Fruit kept under elevated CO₂ concentrations exhibited reduced respiration (O₂ consumption) and ethylene evolution rates, and remained firmer and greener than fruit stored in air. Protein content, fructose 1,6-bisphosphate levels, and ATP:phosphofructokinase and PPi:phosphofructokinase activities declined, while levels of fructose 6-phosphate and fructose 2,6-bisphosphate increased in fruit exposed to air + 10% CO₂. These results are discussed in light of a possible inhibitory effect of CO₂ at the site of action of both phosphofructokinases in the glycolytic pathway, which could account, at least in part, for the observed reduction in respiration.
