Abstract: The tomatoes were treated with 1-Methylcyclopropene (1-MCP) of 0.25, 0.5,0.9μl/L. The hardness, respiration, titratable acid,total soluble solids (TTS), chlorophyll and other indexes of the treated tomatoes were studied . At the same time, the inner structure of those treated tomatoes was also studied with the scanning electron microscope (SEM). The results showed that in a certain range, the effects of fresh-keeping of 1-MCP increased as the increasing of 1-MCP concentrations. 1- MCP lowered the decreasing of the hardness, inhibited the increasing of the respiratory rate, and blocked the chlorophyll’s degrading. 1-MCP can also keep a better condition of the inner structure of the tomato. The best concentration of 1-MCP used in fresh-keeping of tomato was between 0.5μl/L and 0.9μl/L.
