PROBLEM TO BE SOLVED: To obtain an agent for holding plant freshness which can exert a fresh holding effect irrespective of the kinds of cut flowers and vegetables and shows high safety by including a specific antioxidant and a specific surfactant as essential components. SOLUTION: This agent for holding plant freshness is obtained by including (A) an antioxidant capable of inhibiting ethylene biosynthesis or controlling ethylene action and (B) at least one kind of surfactant selected from sugar derivative-type surfactants and sugar alcohol derivative-type surfactants as essential components. It is favorable that the component B is a surfactant having a structure obtained by forming a glycoside-linkage or an ester-linkage between a sugar or sugar alcohol and a hydrophobic group. Further, it is favorable that the weight ratio of the components A to B is 0.0002-1000. The agent for holding plant freshness can be used as a powder preparation containing the components A and B or the like, a concentrated aqueous liquid preparation containing the components A and B in high concentrations or an aqueous liquid preparation used as it is by means of immersion, spray or the like.
