Abstract: In the kiwifruit post-harvest pre-cooling period, two kinds of anti-corrosion smoke agent fumigation before refrigeration was adopted, to study the effect of smoke agent fumigation treatment on post-harvest storage of kiwifruit on physiological metabolism. The results showed that the flesh firmness and fruit ethylene production rate of smoke agentⅠ,Ⅱ and CK kiwifruit have no significant difference throughout the storage period. The fruit respiration rate of using two kinds of smoke agent significantly higher than the CK fruits storied 15d and 28d, indicating the use of antiseptic aerosol after the 28d, the fruit respiration rate was stimulated. Soluble solids content of smoke agent Ⅰfruits was significantly higher than CK fruits ; and softening rate and the decay rate of smoke agent Ⅱfruits was significantly lower than the CK fruits.
