Abstract
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.
