Abstract: In this paper, effect on respiration rate, membrane permeability and pulp firmness of ‘Beijing 14’ peach using 100 kV/m high-voltage static electric field (HVEF) and 50 mg/L spermidine, were studied. The results show that 100kV/m high-voltage electric static field and 50 mg/L spermidine can inhibit the increase of respiration rate and membrane permeability and control the decrease of pulp firmness.
