摘　　要：以新疆塞买提杏为试验材料，用质量浓度分别为0.002、0.01、0.05 g/L的水杨酸（salicylic acid，SA）以减压渗透方式处理杏果实，晾干后于4℃，RH90%~95%的条件下贮藏，定期测定杏果实冷藏期间的呼吸速率、乙烯生成量、1-氨基环丙烷-1-羧酸（1-amino cyclopropane-1-carboxylic acid，ACC）含量、ACC合成酶（ACC Synthase，ACS ）和ACC氧化酶（ACC Oxidase，ACO）活性，探讨SA处理对杏果实呼吸速率和乙烯生物合成的影响。试验结果表明，0.01 g/L SA处理有效抑制了杏果实冷藏期间的呼吸速率、ACO和ACS的活性，明显降低了杏果实ACC含量和乙烯生成量。Xinjiang apricot fruit (Saimaiti) were treated with 0.002, 0.01 and 0.05 g/L salicylic acid (SA) by vacuum-infiltration,respectively. The treated apricot fruits were stored at 4℃and 90%-95%RH for further observation. Respiratory rate, ethylene production, ACC content, ACO and ACS activity of apricot fruits were determined and the effect of SA treatment on respiratory rate and ethylene biosynthesis of apricot fruits was explored. The results showed that the respiratory rate and the activities of ACO, ACS were effectively inhibited by 0.01 g/L SA treatment and the content of ACC and ethylene production in the 0.01 g/L SA treated apricot fruit were obviously lower than those in the control.
