Summary

MITOCHONDRIA WERE ISOLATED FROM < CORTLAND > AND < WINESAP > APPLES STORED AT 90% RH AND EITHER AT 274 OR 278 K (1 OR 5 DEG C). RESPIRATORY CONTROL RATIOS OF MITOCHONDRIA ISOLATED FROM < NURED WINESAP > APPLES STORED AT 278 K WERE CONSISTENTLY LOWER THAN FROM THOSE STORED AT 274 K. SUCCINOXIDASE AND CALCIUM ION ATPASE ACTIVITY WAS HIGHER IN MITOCHONDRIA OF < CORTLAND > APPLES STORED AT 274 K. LARGE INCREASES WERE OBSERVED IN MITOCHONDRIAL CALCIUM ION UPTAKE AFTER 4 WEEK STORAGE OF < NURED WINESAP > APPLES AT 278 K AND AFTER 1 WEEK STORAGE OF < CORTLAND > APPLES AT 274 K. ALTHOUGH NO SYMPTOMS OF CHILLING INJURY WERE OBSERVED, THE MITOCHONDRIAL RESPONSE SUGGESTED CHILLING RESISTANCE IN < NURED WINESAP > APPLES AND CHILLING SENSITIVITY IN < CORTLAND > APPLES.
