摘要: 贮前热激处理能降低贮于低温(0~1℃)下甜椒果实的呼吸上升、乙烯释放和乙醇、乙醛、丙酮等有害物质的积累,减轻低温胁迫造成的果肉细胞膜损伤,增强甜椒果实的过氧化物酶和过氧化氢酶活性,降低苯丙氨酸解氨酶的活性。贮前热激处理有提高甜椒果实的抗冷性,推迟和减轻冷害症状发生的作用。

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.
