Summary

Fruits of mid-('O'Henry'), late ('Fairtime'), and extra-late-season ('Autumn Gem') peach (Prunus persica (L.) Batsch) cultivars were examined for changes in cell wall structure and cytochemistry that accompany the onset of mealiness and leatheriness of the mesocarp due to chilling injury. The peaches were stored at 10 deg C for up to 18 days or at 5 deg C for up to 29 days. Plastic-embedded sections were stained by the Schiff's-periodic acid reaction, Calcofluor white MR2, and Coriphosphine to demonstrate total insoluble carbohydrates, B-1.4 glucans, and pectins, respectively. Mealiness was characterized by separation of mesocarp parenchyma cells leading to increased intercellular spaces and accumulation of pectic substances in the intercellular matrix. Results are discussed.
