Summary

KAISER PEARS, HARVESTED ON TWO DATES, WERE IMMEDIATELY HYDROCOOLED OR HELD 6 DAYS AND THEN STORED IN CA (2-3% CO2 AND 4-5% O2). PITHY BROWN CORE DID NOT APPEAR AT THE END OF COLD STORAGE BUT ONLY AFTER 4 DAYS AT 297 K (24 DEG C). DELAYED STORAGE INCREASED WEIGHT LOSS, SHRIVELLING AND PITHY BROWN CORE, BUT HAD A POSITIVE EFFECT ON EARLY HARVESTED PEARS WHICH RIPENED COMPLETELY. HYDROCOOLING SIGNIFICANTLY DECREASED SHRIVELLING AND PITHY BROWN CORE, MOSTLY AMONG THOSE MORE SUSCEPTIBLE TO THE DISORDER, IE LATE HARVESTED OR WITH DELAYED STORAGE. HYDROCOOLED PEARS AT THE END OFCOLD STORAGE SHOWED HIGHER TITRATABLE ACIDITY AND LOWER SOLUBLE SOLIDS THAN THOSE AIR COOLED, BUT THE DIFFERENCES DISAPPEARED AFTER 4 DAYS AT ROOM TEMPERATURE. HYDROCOOLING DID NOT AFFECT WEIGHT LOSS NOR INCIDENCE OF ROT.A. M.
