CHILLING SENSITIVITY OF TOMATO FRUIT IN RELATION TO RIPENING AND SENESCENCE.

Author(s) : AUTIO W. R., BRAMLAGE W. J.

Type of article: Article

Summary

CHILLING SENSITIVITY, AS MEASURED BY ION LEAKAGE, FIRST DECLINED AS THE TOMATOES BEGAN TO RIPEN AND THEN INCREASED DURING THE LATE STAGES OF RIPENING. BOTH C2 H4 BIOSYNTHESIS AND RESPIRATION RATE WERE STIMULATED DURING THE CHILLING RESPONSE EARLY IN RIPENING. IN THE NONRIPENING MUTANT, CHILLING SENSITIVITY DID NOT SHOW THE EARLY DECLINE BUT SHOWED THE INCREASE DURING SENESCENCE. VARIATION IN CHILLING SENSITIVITY DURING RIPENING WAS BIPHASIC, WITH A DECLINE AT THE ONSET OF RIPENING FOLLOWED BY A SENESCENCE-RELATEDN. THE LATTER MAY BE DUE TO AN INCREASE IN MEMBRANE VISCOSITY.
