RESPIRATORY ENZYME ACTIVITY IN LOW TEMPERATURE SWEETENING OF SUSCEPTIBLE AND RESISTANT POTATOES.

Author(s) : BARICHELLO V.

Type of article: Article

Summary

DURING STORAGE AT 277 AND 285 K (4 AND 12 DEG C), A POTATO CULTIVAR SUSCEPTIBLE TO CHILL-SWEETENING (NORCHIP) ACCUMULATED SIGNIFICANTLY HIGHER LEVELS OF SUCROSE, FRUCTOSE AND GLUCOSE THAN A POTATO SELECTION RESISTANT TO CHILL-SWEETENING (ND 860-2). ND 860-2 TUBERS EXHIBITED A SIGNIFICANTLY HIGHER RESPIRATION RATE THROUGHOUT STORAGE, REFLECTED IN HIGHER ACTIVITIES OF PHOSPHOFRUCTOKINASE, GLUCOSE-6-PHOSPHATE DEHYDROGENASE AND 6-PHOSPHOGLUCONATEDEHYDROGENASE. STORAGE SIGNIFICANTLY REDUCED RESPIRATION RATE FOR BOTH CULTIVARS.
