Effect of exogenous salicylic acid on anti-chilling-injury of postharvest apricot fruit

Xinjiang apricot fruits “Saimaiti” were used to investigate effects of 0.01g/L salicylic acid treatment combined with controlled vacuum-infiltration, then stored at 0℃, RH 90% ⁹5%.Apricot fruits treated with distilled water were as the control.The effect of salicylic acid on cold resistance of apricot fruits was studied.Apricot fruit chilling injury incidence, chilling injury index, hardness, juice rate, membrane permeability, MDA content of apricot fruits were determined every 7d.Results showed that postharvest treatment could obviously reduced the chilling injury incidence rate, chilling injury index, permeability, MDA content (p <0.01) ;could efficiently keep apricot fruit hardness and juice yield by 0.01g/L salicylic acid (p<0.05) .Results of the study suggest that, the exogenous salicylic acid treatment could improve the cold resistance of apricot fruit.
