Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for early-cultivating statice sinuata. In terms of classification, Sinusata is a genus of Statice (currently of the genus Limonium. However, since the traditional name of statice is easier to understand, it is one of the genus Staticus), which is one of the genus Sinuatum (Sinusata). It is). In addition, since it is usually referred to as staticy sinuata, it is also referred to as staticy sinuata here. The family to which the genus Staticis (Limonium) belongs is
It is a pine tree. There are about 300 species in the world, and they grow naturally on the coast and inland drylands. In Japan, there are also horse mackerel, horse mackerel, etc. When we call statices in flower shops, we often refer to statices sinuata.

It is a perennial plant with many rooted roots, evergreen, pinnate fissures and wavy edges. There is coarse hair in the whole strain. The flowers are small and numerous, the inflorescences are large, and the stems are bifurcated, forming a cuboidal eccentric gyrus. The stem is cylindrical and has wings of 3 to 5 fissures, and branches to form a compound inflorescence as a whole. The spikelet is an eccentric inflorescence, and the inflorescence consists of 3 to 5 flowers. The calyx has a membranous tubular funnel shape and is colored in purple, white, yellow, peach, apricot, and looks like petals. Five petals, which are white or yellow, are formed at the base. The place of origin is the Mediterranean coast, the plant height is 60 to 90 cm, and it is a semi-cold-resistant perennial plant. In commercial cut flower cultivation, it is often handled as an annual plant because it is difficult to survive in the summer and productivity of old plants decreases. Garden varieties come in many colors. Drying each will give dried flowers.

[Prior art]

(Conventional flowering cultivation method) Statice sinuata is a perennial plant sown in the fall and is sown in the fall at low temperature (about 40 days at 10 ° C for 1 day).
After encountering at 70 ° C for 5 days, flower buds are attached. Flowering is usually done in a non-heated greenhouse, from early spring to early summer of the following year. When sown in the summer, it becomes a rosette shape over the fall to winter,
It does not bloom that year, but blooms the following spring. Therefore, if seeds are sown in the summer and cut flowers are to be produced in the late fall and winter, the seeds must be vernalized. This means that vernalization of seedlings is necessary to produce cut flowers from late autumn to winter even in the case of seedlings grown by the plant tissue culture method.

[0004]

In the case of cut flower production from seeds, in general, vernalization treatment is described. The seeds are put in an appropriate container and allowed to absorb water, and 1-2 days later, the embryos start to move. From this, refrigerate at 2 ℃ ~ 3 ℃, but germinated 30
After a day, the seedlings are managed in a cool place (20 ° C) [17 ° C or less at night]. By the above method, forcing culture of statice sinuata became possible. However, the cultivation method by the above low-temperature treatment method has a drawback that it is troublesome.

[0005]

Therefore, as a result of various studies, the present inventor has invented the following method for premature cultivation of statice sinuata. That is, as specified in the claims of the present invention, the strains of the varieties used by Staticis sinuata are cut back at a distance of 3 to 5 cm from the ground level to generate axillary buds, and the axillary buds are extracted from the above-mentioned lottery stand. It was found that early flowering can be expected by separating it from the later strain [hereinafter referred to as the original strain], inserting it into a cutting bed and growing it.

[0006]

[Example] As for the variety to be used, the original strain was cut back from the ground by 3 to 5 cm above the ground level using sopia, and a few days later, the axillary buds grew (after 2 weeks in this example), the original strain was used. After digging up, the axillary buds are cut from the original stock with a knife and the buds are cut. [In some cases, axillary buds (which are referred to as high buds) that grow midway on the flower stem can also be used. ]

[0007] Culture soil, for example, a mixture of perlite and peat moss, was used for the inoculation bed, and as a rooting agent, Shionogi Pharmaceutical Co., Ltd. trade name oxyberon liquid agent (indole butyric acid liquid agent)
1000 PPM is dipped (liquid) or applied (powder) on the cut surface of the axillary bud. Then, a mist device was installed on the bed to keep a proper humidity, and prompt rooting was promoted.

Four test plots were set according to the timing of cutting back and cutting of the original strain. Return of original stock is May 1, 6
It was held on the 1st of the month, the 1st of July, and the 1st of August. The axillary buds sprouted by the above reverting work were
The shoots were sprouted on June 15, July 15, and August 15.
The rooted seedlings were hardened, raised in a No. 3 plastic pot, raised, and placed in a wooden box [35 × 60 cm, depth 18 c.
m], and 6 plants were planted into 1 box and 2 boxes.

All the flower stalks that had come up to August 31 were cut off early in order to grow and enhance the plants so that cut flowers could be harvested from late autumn to winter. I investigated the flowers that came up after that.

Flowering investigation The flowering date, number of flowers, flower length and weight were investigated for each plant. From October 28, room temperature was warmed to a minimum of 12 ° C.

The stocks in the ward on May 15 are from early July to 8
Until late March, the flower stalks were being pulled, but after August 31st, it was very suppressed, probably because of high temperatures. The average number of cut flowers was only 5, but the quality was good (see Table 1). Since February, it has been sensitive to the low temperature, so it has been drawn again.

Regarding the strains of the plots inserted on June 15, only the flower stems grew, some did not reach flowering, and some rosette-shaped. However, the pastel pink plant was partially necrotic after the flower stem had grown (about 5 to 10 cm), but it reached flowering and the plant height was slightly lower than usual. The cause of necrosis is not clear, but if the cause is clear, a pastel pink strain will be possible in June. (See Fig. 2)

The stocks in the ward of July 15 are from late September to 1
Flowering started in early October. After that, the number of cut flowers per plant will be 10 to 30 until early March, and the difference in the number of cut flowers will vary greatly depending on the strain (see Fig. 3). If the cuttings and rooting seedlings are not strong, the number of cut flowers and quality will be high. It became clear that it would decrease.

As for the strains of the sect which was inserted on August 15, the seedlings that had been subjected to high temperature were sprouting as the original strains, so that all the strains became rosettes and did not bloom.

[0015]

[Table 1]

If the temperature of the statice does not rise up to a temperature of about 15 ° C., when the seedling or the plant receives high temperature, it becomes a so-called high temperature rosette. Therefore, there is a suitable period for cuttings to bloom in late autumn to winter. That is, it can be found that if the cuttings are too early, the inserted seedlings will be subjected to a high temperature later and will not be drawn, and if the cuttings are too late, the original strain will be subjected to a high temperature and the seedlings inserted from it will not be drawn. It was From the above, it was confirmed that mid-July is a suitable period for cuttings and buds to fully bloom in winter.
(See Fig. 4) However, when cultivating seedlings produced by this method, after planting, the seedlings must be grown to a certain extent and made into a solid plant. It is important to note that early flowering before the plant becomes a large plant will weaken the plant and reduce the number of cut flowers and quality.

[0017]

As described in detail in the above-mentioned configuration (described in the claims) and the embodiments thereof, the present invention eliminates the need for a very troublesome method such as low-temperature treatment which has been conventionally performed, and the cutting and splicing are performed. It is an excellent invention that allows for the breeding and early flowering of statice sinuata by a simple method in a timely manner.
