RESPIRATION OF BANANA FRUIT IN RELATION TO CHILLING INJURY.

TROUBLES RESPIRATOIRES ASSOCIES A LA MALADIE DU FROID DE LA BANANE.

Author(s) : MARCELLIN P., DICK E.

Summary

THE RESPIRATORY QUOTIENT (RQ) OF CERTAIN FRUITS HAD BEEN FOUND TO BE LESS THAN UNITY FOR THE FIRST DAYS AT CHILLING TEMPERATURE AND THEN ROSE MORE OR LESS FASTLY TO FERMENTATIVE VALUES. A COMPARATIVE STUDY OF RQ EVOLUTION WAS INVESTIGATED IN BANANAS (MUSA CAVENDISHII L) AT 277 AND 285 K (4 AND 12 DEG C). WHEN O2 UPTAKE BY DISKS OF PEEL OR PULP TISSUES WAS MEASURED OVER A RANGE OF CHILLING AND NON CHILLING TEMPERATURE A BREAK IN THE ARRHENIUS PLOT OCCURRED AT 285 K FOR PEEL. IN THE PRESENCE OF MAXIMAL INHIBITORY LEVELS OF CYANIDE AND SALICYLHYDROXAMIC ACID A LARGE RESIDUAL O2 UPTAKE REMAINED. EXTRA-MITOCHONDRIAL OXIDASES MAY HAVE A ROLE IN DECREASING RQ AT CHILLING TEMPERATURE.
