Abstract

PURPOSE:To preserve bulbs or the like obtained by tissue culture by packing the bulbs, etc., into a film of material having properties to permeate oxygen but not viruses or by coating with a solution of a material having the same properties and water solubility. CONSTITUTION:Bulbs of lily, narcissus, tulip, etc., or strains of orchid, etc., obtained by tissue culture in a sterile state are packed into a film of a material (e.g., hydrophilic polyolefin or polyvinyl alcohol of porous resin) to permeate oxygen but not viruses or put in a container made of the material, sealed and stored. Or the bulbs, etc., are sprayed with a solution of a material (e.g., cellulose acetate phthalate) to permeate oxygen but not viruses and to have water solubility, coated with the solution by a brush or immersed in the solution and coated to store the bulbs, etc. In the case of the latter, the bulbs can be directly planted as it is or can be subjected to water culture.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to the use of bulbs such as lilies, daffodils, tulips, crocuses, hyacinths, anemones, Western orchids, Japanese orchids, etc. that have been tissue cultured under aseptic conditions. This invention relates to a method for preserving plants and bulbs for flower and tree cultivation (hereinafter simply referred to as bulbs, etc.).

BACKGROUND OF THE INVENTION In recent years, various types of bulbs, including orchids, have been mass-produced by tissue culture. The bulbs etc. obtained in this way are usually small in size but have vigor and are characterized by large flowering. It was then shipped.

Problems to be Solved by the Invention In order to cultivate bulbs, etc. at home, it is necessary to preserve the produced bulbs, etc. so that they do not rot or become susceptible to pests and diseases before being cultivated. .

Bulbs obtained through natural cultivation are often placed in a plastic net after drying and stored in a shady, well-ventilated place, but those grown in tissue culture under sterile conditions are smaller in size, as mentioned above. If they are stored in the same way as before, they will become contaminated with viruses and lose their vitality, resulting in them not being able to bloom, or even if they do bloom, the flowers will be small.

In order to solve this problem, the present invention makes it possible to store spheres II and the like obtained by tissue culture in a sterile state.

Means for Solving the Problems The present invention therefore involves packing tissue-cultured bulbs, etc. with a film made of a material that allows oxygen to pass through but not viruses, or sealing and storing them in a container made of the above-mentioned material. This is what I did.

Examples of materials that allow oxygen to pass through but do not allow viruses to pass through are:
Polyolefin that imparts hydrophilic properties to porous resins, polyvinyl alcohol, cellulose acetate, regenerated cellulose, polypropylene, polyethylene, polyethylene copolymers,
Examples include cellulose mixed ester resin and fluororesin.

Examples of bulbs include tissue-cultured bulbs such as lilies and tulips, and stocks of Western orchids and Japanese orchids.

In another invention, Mi weave-cultured bulbs, etc. are sprayed with a solution made of a water-soluble material that allows oxygen to pass through but does not allow viruses to pass through, or is coated with a brush, or immersed in the solution. It is coated with

Examples of water-soluble materials that allow oxygen to pass through but do not allow viruses to pass through include cellulose acetate phthalate, methyl methacrylate, methacrylic acid, methyl acrylate methacrylic acid, synthetic products such as polymers, cellulose, Examples include natural products such as modified starch, and these materials dissolve and decompose when immersed in near-neutral water.

Working bulbs and the like are preserved in a sterile state without becoming necrotic when they come into contact with oxygen.

If the plant is packed with film or sealed in a container, the film must be torn or peeled off during cultivation, or the bulbs etc. must be removed from the container and planted. However, if the material of the film or container is water-soluble, You can grow it hydroponically by planting it as it is or soaking it in water.If it is photodegradable, you can grow it hydroponically in a glass pot, or use light-transmitting non-woven fabric or Mitsui Petrochemical Industries Ltd. It can also be cultivated using the product name Clear Pearl (a water-swellable product of a water-swellable gel-like crosslinked polymer).

! If L1111 or the like is coated with a water-soluble material that allows oxygen to pass through but not viruses, it can be planted directly in the soil, or it can be cultivated using hydroponics or the above-mentioned clear pearls.

After planting, the coating material is dissolved and decomposed by irrigation or contact with water.

Embodiment In the embodiment shown in FIG. 1, bulbs 2 are planted on one side of a thin porous film tape 1 made of polyethylene at equal intervals to the spacing, and in the same direction as the sprouts, using glue or the like. After adhering using adhesive tape 1, a tape 1 made of the same material was laminated and sealed. During cultivation, normally the tape on the front side is peeled off, and then the bulbs 2 are attached and planted together with the tape, but in some cases, the tape is removed separately or the bulbs 2 are taken out one by one and planted. You can also attach it. Furthermore, if the tape 1 is water-soluble or light-transparent, it is possible to plant the tape as it is without peeling it off, or to perform hydroponic cultivation by soaking it in water. When cultivating bulbs that can be cultivated in a sealed manner, a dressing or soil may be added in advance.

In the embodiment shown in FIG. 2, bulbs 4 are placed in capsules 5 made of porous material and sealed.
The seeds are removed from the capsule 5 and planted, but if the capsule is water-soluble or light-transmissive, the seeds can be left in the capsule and cultivated in the same manner as above.

When sealing the case in this embodiment, it may be sealed to an appropriate degree of vacuum under reduced pressure, and at this time, carbon dioxide gas or nitrogen gas may be filled alone or with gas adjusted to an appropriate mixing ratio.

324 shows bulbs 7 arranged vertically and horizontally on one side of the sheet 6, and each bulb is sealed with a box-shaped cap 8 made of a porous material; FIG. Bulbs 7 are arranged on one side at equal intervals and covered with a cap 8 as described above, and during cultivation, the bulbs 7 are taken out one by one and planted.

In another embodiment, the bulbs are coated by immersion in an aqueous solution of a porous and water-soluble material, such as a modified starch.

Effects of the Invention The present invention is configured as described above, and has the following effects.

The method according to claim 1 is a method in which bulbs etc. cultured with &lla are banked with a film or placed in a container and sealed.Since bulbs etc. cultured &lva are small in size, they can be banked even with a thin film. Films and containers allow oxygen to pass through, but do not allow bacteria to pass through, allowing tissue cultured spheres to be stored for long periods of time in sterile conditions without causing necrosis, resulting in virus-free vitality. It has the effect of being able to obtain certain bulbs etc. at any time.

According to the method of claim 2, the bulbs, etc. are coated with a water-soluble material that allows oxygen to pass through but does not allow viruses to pass through, so that the bulbs, etc. can be stored for a long period of time in a sterile state without causing necrosis. In addition to being able to
It can be grown by planting in soil or by hydroponics.
