Abstract: Physiologicaleffectsofheatshock treatmentonsweetpepperstoenhanceitsresistancetochillinginjuryw ere studied.The results showed that the heat shock treatment could lower the respiration rate and the amount of ethylene released,reduce the accumulationo f alcohol,acetaldehyde and acetone,lightenthe chilling injury of memb rane,en-hance the peroxidase activity andca talase activity andreduce the phenylalanine ammonia lyase activity ofsweetpepper stored at low -temperature(0~1℃).Heat shock treatment of prestorage can enhance resistance to chilling i njury of sweet pepper,postpone the symptomo f chilling injury appearing andligh ten the degree of chilling injury.
