Abstract

The diffusivities of O₂ and CO₂ ofexocarp plus pericarp, pericarp, and stem scar of tomatoes were measured by the 'time lag' method. The O₂ and CO₂ diffusivities of stem scar of green stage tomatoes were 0.72 × 10^-8 m²/s (7.75 × 10^-8 ft²/s) and 0.30 × lO^-8 m ²/s (3.2 × 10^-8 ft²/s), respectively. They were 2- to 4.3-fold higher than those of exocarp plus pericarp and pericarp. All measurements were done at 21° C (70° F). The gas diffusivity values of all components studied increased during the ripening process.
