Summary

SEED-TUBERS OF THE CULTIVARS MANTIQUEIRA AND BINTJE WERE STORED AT 278, 283, 293 K (5, 10, 20 DEG C) + OR -1 K AND AT AMBIENT TEMPERATURE: 291 TO 300 K (18 TO 27 DEG C) AND KEPT IN THE DARK FOR 154 DAYS. RESPIRATION RATE AND DRY WEIGHT LOSS WERE DETERMINED. RESPIRATION RATES INCREASED AT HIGHER TEMPERATURES WITH TUBERS AGING ABOVE 278 K IN BOTH CULTIVARS. HOWEVER, THEY WERE APROXIMATELY CONSTANT AT 278 K. DRY WEIGHT LOSSES WERE DIFFERENT. THERE WAS AN INCREMENT IN ACTIVATION ENERGY AS TUBERS BECAME OLDER IN BOTH CULTIVARS, LEADING TO THE CONCLUSION THAT THE RESPIRATION BECOMES LESS EFFICIENT WITH TIME.
