Abstract: To investigate the effect of 1-MCP on the postharvest simulate transportation and shelf quality of‘Guichang ' kiwifruit. Firstly the best taste samples were obtained by shelf display,and fruits were fumigated24 h by using different concentrations(0.5,0.75,1 mg/kg) of 1-MCP,loaded in cardboard boxes with the speed of 100 km/h simulation of transport 5 d,then tested shelf index every three days. The results showed that :1-MCP could better maintain fruit shelf quality,and rot rate,MDA content,respiration intensity,ethylene release rate. It could delay the decreasing of hardness,V_C content,SOD activity. And the ratio of total soluble solids and total titratable acids,chlorophyll and reducing sugar were better maintained. However 0.75 mg/kg concentration of 1-MCP had the best shelf quality of kiwifruit. The principal component analysis showed that the best texture close to S0 was in sequence of sample 1(control,5 d),sample 8(0.75 mg/kg,11 d),sample 7(0.75 mg/kg,8 d). It proved that 0.75 mg/kg could better maitain the best mouthfeeland shelf life of kiwifruit,and delay the shelf life in the basis of rot rate and best mouthfeel about 11 d. In consquense,treatment with0.75 mg/kg 1-MCP could provide the best shelf quality effect of kiwifruit.
