Type of article: Article

Summary

MATURE-GREEN TOMATO FRUIT FROM 2 CHILLING-SENSITIVE CULTIVARS AND 2 CHILLING-TOLERANT BREEDING LINES WERE CHILLED AT 278 K (5 DEG C) FOR 0, 2, 7 AND 15 DAYS. MATURE-GREEN FRUIT ANALYZED IMMEDIATELY AFTER CHILLING SHOWED HIGHER ELECTROLYTE LEAKAGE IN CHILLING-SENSITIVE THAN CHILLING-TOLERANT LINES. HOWEVER, ELECTROLYTE LEAKAGE FROM CHILLED FRUIT THAT WERE RIPENED BEFORE ANALYSIS WAS HIGHER IN NORMAL-SIZED THAN IN CHERRY CULTIVARS AND SEEMED TO BE A FUNCTION OF FRUIT TYPE RATHER THAN OF CHILLING SENSITIVITY. UNCHILLED FIELD SAMPLES OF THESE CULTIVARS HARVESTED AT THE MATURE-GREEN, TURNING, AND FULL-RIPE STAGES AND ANALYZED IMMEDIATELY SHOWED AN ELECTROLYTE LEAKAGE PATTERN SIMILAR TO THAT FOUND FOR COMPARABLE CHILLED MATURE-GREEN FRUIT.
