2. Description of the Related Art At present, flower growers usually ship cut flowers in the form of buds. However, as time elapses, such as when adjusting shipping, the buds open, and as a method of avoiding this, they are generally stored by immersing them in water in a refrigerator at 0 ° C to 5 ° C. For example, it is also known that a refrigerator stored at 2 ° C. to 5 ° C. for 2 days to 5 days maintains its freshness for 3 days to 5 days, at most for about 1 week.
However, the fresh flowers have a respiratory action even at the above temperature, and the buds bloom.

[0003] To prevent the buds from opening before shipment, a method of protecting the buds with a tape or a vinyl-like small bag or the like, or extending the life for about one week by performing a chemical treatment has been adopted. For example, carnations in the bud state are cut off early and treated with ethylene. At temperatures of 15 ° C to 20 ° C, the carnations are drained and held for 1 to 10 days after the flower opens, and for 2 weeks at longest. It is known that, when the temperature is 20 ° C. or more, the freshness is maintained for at most three to five days, at most for about one week.

[0004] Further, there has been proposed a life-prolonging method in which a physiological condition such as respiration is stopped and a bud is not opened by creating a suspended state at a minus temperature. However, there is an inherent problem that this method and the above-described method are troublesome, cost is increased, and the price of flowers is also increased.
