摘要： PURPOSE:To provide a cut flower freshness-retaining agent mainly comprising a silver ion-releasable substance such as an inorganic antibacterial agent, sucrose and water, and readily handlable not deteriorative and having a sure activity. CONSTITUTION:A substance capable of eluting silver ions and sucrose are charged to and mixed with water to obtain a cut flower freshness-retaining agent. The substance capable of eluting the silver ions includes inorganic antibacterial agents such as antibacterial zeolite, antibacterial alumino silicate, antibacterial interlaminar compound and antibacterial dissolvable glass, and the employment of the inorganic antibacterial agent particles permits to gradually release silver ions in a low concentration to produce silver colloids stably and continuously, thereby giving a remarkable effect on retaining the freshness of cut flowers. When the agent is used, the sucrose and the silver ion-eluting substance are separately or together added to water and cut flowers are arranged in the solution. The agent may be compounded with a silver ion-stabilizing agent, a pH-adjusting agent, a colorant, a water-sterilizing agent, etc.
