Control of low temperature injury in witloof chicory.

 

Postharvest chilling injury seriously affected chicory quality in the 1985/86 season in the Netherlands. Results of experiments carried out subsequent to that on the roles of various factors in chilling injury occurrence are reported. Field trials at various locations found no significant link between root K:Ca ratio and the incidence of the disorder, although in other trials a high K content was linked with small, poor quality heads. In hydroponic forcing trials, chilling injury incidence increased with increasing nutrient solution K concentration and decreased greatly when the temperature was lowered from 16 or 20 deg C to 12 deg one day before harvest; cooling the harvested chicons to 1 deg within 4 h of harvesting greatly reduced chilling injury incidence.
