Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a preservative and a method for preserving ornamental plants, and more particularly to ornaments that can be preserved for a long period of time without changing the natural morphology and texture of the plant, especially while retaining the fragrance. The present invention relates to a preservative and a method for preserving plants, and an ornamental plant produced by the preserving method.

2. Description of the Related Art In recent years, even after cutting plants such as flowers and trees from the natural environment, the stems of plants are immersed in an aqueous solution of a preservative for the purpose of viewing it indoors for a long period of time. Various techniques have been developed to preserve the natural state by absorbing it. The preservatives used in these methods are to be absorbed in plants to retain water in the plants, and conventionally glycols such as glycerin have been used. Further, in order to promote absorption of the preservative, the preservative may contain an accelerator such as an alkali metal salt or an alkaline earth salt, if necessary. (JP-A-62-89601, JP-A-1-311002, JP-A-2-268101, JP-A-4-53418)

On the other hand, in flowers, it is more ideal if the scent of flowers can be maintained in addition to keeping the form and color in a natural state. However, the conventional plant preservatives focus only on maintaining the form and color in a natural style for a long time, and have not paid attention to the aroma retention of flowers. Slightly, as a method of preserving cut flowers, there are some that focus not only on shape and color but also on scent (Patent Application Publication No. 4-505766), but in this method, the flower part is placed in an organic solvent bath, Bath surface is more than flower height
It must be dipped so that the height is cm, and there is a troublesome point such as a holder grid and a support such as a molecular sieve are required to mechanically support the petals and prevent distortion. Flowers suitable for this treatment include roses, peony, orchids, and carnations.
Many flowers are not suitable for this treatment method.
