The present invention relates to a method of breeding bamboo shoots. More specifically, the present invention relates to a method of breeding bamboo shoots, which can obtain flowering fruit in a short time using the cutting breeding technique.

The name 'Jukjeolcho (竹節 草)' is named because the stems have bamboo-like nodes but are soft like grass. Bamboo shoot is a plant of the genus Phloisaceae , the scientific name is Chloranthus glaber (Thunb.) Makino. It is an evergreen broad-leaved shrub, and its height is about 1m. The leaves are alternate students and the flowers are water inflorescences. Fruits ripen from 5 to 10 red in October and hang all winter. Yeongeun red fruits at the end of branches are like burning candles and are very likely to be used for cut flowers or landscaping.

Jukjeolcho in Korea grows near the southern valley of Jeju Island. Jukjeolcho is distributed not only in Korea but also in Japan, China, Taiwan, India, and the Philippines. Especially in Japanese, Senryo is used to mean something very valuable. It is an evergreen tree and bears red fruit in the cold winter, and it is considered to be long. The red fruit is like coral color, so it is named expensive (heaven). In addition, the red color of the fruit is thought to chase after the ghost, and at the beginning of the New Year, bamboo jeolcho is decorated around the house.

However, there is almost no landscape use of bamboo shoots in Korea. As of May 2006, bamboo tree vinegar was excluded from the landscaping tree price table set by the Public Procurement Service and Landscaping Association. Nevertheless, the authors who introduced bamboo shoots highly value the landscape value of bamboo shoots and agree that the potential for use for differentiation and cut flowers is very high.

One of the obstacles to the landscape use of bamboo shoots is that the general breeding of bamboo shoots (sowing seeds) takes more than six years to achieve flowering. Therefore, it can be said that it takes a lot of time to commercialize bamboo leaf vinegar whose red fruit is life.

Therefore, the present inventors completed the present invention by investigating the landscape characteristics of bamboo shoots and studying the breeding method for early deletion, and finding that early flowering deletion can be obtained when the cutting breeding technique is used for the breeding method of bamboo shoots. .

Therefore, the technical problem of the present invention is to provide a method of breeding bamboo shoots that can be commercialized for differentiation or cut flowers by inducing early flowering deletion of high bamboo shoots.

In order to achieve the above technical problem, the present invention
Cutting the tip of bamboo shoots branched with a cloth shovel into 15 to 25 cm;
Treating the cut cloth shovel with 100 to 1,000 mg / l root promoting plant hormone in order to root the root and the root of the cut cloth shovel;
Inserting a hormone treated shovel; And
Provided is a method of propagating bamboo shoots comprising transplanting seedlings rooted 3 to 6 months after cutting.

In the bamboo shoot reproductive method according to the present invention, the rooting promoting plant hormone is indole-3-butyric acid (IBA), alpha-naphthalene acetic acid (α-naphthalene acetic acid (NAA)), indole- Preferably it is selected from the group consisting of 3-acetic acid (Indole-3-acetic acid (IAA)) and commercialized plant growth regulator luton (1-naphthylacetamide 0.4%), wherein the hormonal treatment step is the cleaved shovel In order to root the roots and the roots in the root is preferably immersed for 10 seconds to 10 minutes plant hormone in the rooting plant hormone 100mg / l to 1,000mg / l to promote rooting.

In addition, the cutting step in the bamboo shoot reproductive method according to the present invention is a step of planting a hormone-treated cloth shovel on a shovel containing shovel soil, and maintaining the humidity of 80 to 90% for the development and growth of bamboo shoot root It is preferable to include, and the cutting phase is preferably a plate made of wood of 30 to 50 cm.

Hereinafter, a method of breeding bamboo shoots according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the method of breeding bamboo shoot vinegar according to the present invention is a step (S11) to cut the bamboo shoots the end of the bamboo shoot (branch) to 15 to 25cm; Treating the cut cloth shovel with 100 to 1,000 mg / l of plant root promoting plant hormone (S12); Inserting the hormone-treated cloth shovel (S13) and transplanting the seedlings rooted 3 to 6 months after the cutting (S14).

The cutting step (S11) may collect a certain portion of bamboo shoots, for example, a strong middle part of the new branch (greenery) or more than two years old (mallow) in that year, Harvesting is most preferred for early flowering deletions, with a length of 15-25 cm, and most preferably 20 cm.

The hormone processing step (S12) is to process the cut cloth shovel with a hormone. Here, hormones may be used in the general plant hormone in this field that can promote rooting, preferably selected from the group consisting of IBA, NAA, IAA, and commercialized plant growth regulator luton (1-Naphthylacetamide 0.4%) Can be. Most preferably IBA.

The amount of the hormone to treat the shovel can be used in the range of 100 to 1,000 mg / l, when used below 100 mg / l, can not promote rooting as expected, used in excess of 1,000 mg / l In this case, the rooting promotion efficiency cannot be expected as much as it is used, which is not preferable.

On the other hand, the method of treating the shovel with a hormone can be used in the general method of the art, but preferably, the chopped shovel is immersed in the rooting plant hormone 100 to 1,000 mg / l for 10 seconds to 10 minutes.

Plant hormone soaking time is reasonable for 10 minutes at low concentration of 100mg / l, 10 seconds at high concentrations of more than 2000mg / l. If the concentration is lower than 100mg / l, the immersion time should be extended from 1 hour to 24 hours, in which case it takes a lot of time to cut. At high concentrations of 2,000 mg / l or more, 5 seconds or instantaneous immersion may be possible, but depending on the plant, it may cause high concentrations of phytohormones, and it may be economically poor considering the price of expensive phytohormones.

The cutting step (S13) includes planting a hormone-treated cloth shovel on a shovel containing shovel soil and maintaining proper humidity for the development and growth of bamboo shoot root.

The cutting can be used in the general field in this field, but the general cutting is about 10cm to insert the place where the cutting depth of about 10cm. Bamboo cut is 30 to height because it is preferable that the cut section of bamboo cut is long like bamboo It is made of wood having a height of 50 cm, preferably a height of 40 cm. On these cuttings, drainage is good and humidity is well maintained. Therefore, it is most preferable that the cutting phase has a size of, for example, 1.5M x 1.5M x 0.4M.

The soil may be used as the general soil in this field, but the general soil is used sand or vermiculite alone or mixed soil of vermiculite and perlite, in which case it only induces rooting from the cuttings and 30 to 40 days after cutting This is because the purpose is to transplant it into the soil. In other words, rooting in the cuttings is due to the nutrition of the cuttings themselves, and soil nutrients are not relevant. However, the roots of bamboo shoots are characterized by the fact that the roots develop well after 90 days without the roots. In this characteristic, if the main roots occurred 30 to 40 days after cutting, transplantation would result in the death of the plant without adaptation to the transplanted environment without the roots to absorb nutrients in the soil. Therefore, in order to wait about 90 days for the development of the roots on the cuttings, it is preferable that the soil is mixed with nutritious peat moss in addition to the existing general shovel soil. most Preferably, a mixture of vermiculite: pitmos: pearlite is 1: 1: 1 (v / v / v) is used.

On the other hand, it is preferable to maintain an appropriate humidity so as not to wither until the roots, and the appropriate humidity is preferably 80 to 90%.

Transplanting the root seedlings in minutes (S14) is preferably transplanted after three to six months on the cutting after insertion. A more desirable time is to cut the plants in May, especially in the middle of May, and then in summer to transplant them into pots in October. This is because the seedling roots of bamboo shoots have almost no roots, so they are rooted in 30-40 days, which is a general transplanting season. Therefore, on deep cuttings it is desirable to delay the transplantation time until the roots are fully developed.

Hereinafter, the present invention will be described in detail with reference to the following examples, but the present invention is not limited by the following examples.

Example  One

Jukjeolcho test materials used in this experiment were collected from the test package of Nandae Forest Research Institute in Jeju Island. In general, it is important to secure fresh parameter material in cutting experiments. Therefore, the cutting materials used in this experiment were used immediately after the air collected from Jeju Island.

On May 4, 2005, cut the shovels from bamboo shoots to 20 cm long, and then immerse them in rooting plant hormones, IBA 100 mg / l, IBA 1,000 mg / l, IBA + NAA 1,000 mg / l. Hormonal treatment. For comparison, experiments were also performed on untreated controls that did not receive rooting plant hormonal treatment. The treatment time was 10 minutes at 100 mg / l and 10 seconds each at 1,000 mg / l and 1,000 mg / l of IBA + NAA, followed by vermiculite: Pitmoss on a wood cutting of 1.5M x 1.5M x 0.4M. : The mixed soil of pearlite (1: 1: 1, v / v / v) was filled, and a hormonal treated horde was planted. The seedlings rooted around October 5 were then transplanted into the moss after periodic hydration (eg, until water was sufficiently absorbed on the insert once a day).

The rooted seedlings were photographed and the results are shown in FIG. 2, and the rooting rate, root number, and root length were examined from the rooted seedlings, and are shown in Table 1 below.

badge Rooting rate (%) Logistics No. of roots Root length (cm)  Vermiculite: Pitmos: Pearlite = 1: 1: 1 Control group (n = 8) 90 10 6.0 Rooton (n = 8) 100 6.5 6.5 IBA 100 mg / l (n = 8) 100 8.3 7.0 IBA 1,000 mg / l (n = 8) 100 12.0 11.5 IBA + NAA 1,000 mg / l (n = 8) 100 7 6.0

In Table 1, Rooton (ruton) refers to a commercialized plant growth regulator luton (1-naphthylacetamide 0.4%) among the rooting promoting plant hormones, and the luton used in the present invention is classified as a low toxicity pesticide and registered number ' As 13-Saengjo-4 ', the manufacturer is Ishihara Sangyo Co., Ltd. in Japan, and is a domestic commercial product used in farms in Kokki-si.

On the other hand, at the bamboo shoots of Jukjeolcho, which was inserted on May 4, 2005, red berries were enjoyed that winter. Bamboo shoot seedlings continued to grow during the summer, bloomed and fruited, producing red fruits that winter. In Example 1, the red fruit was English and 62.5% of 1-year-old Cheon Sapling fruit was observed in 25 out of 40 Cheon Sapling seedlings. That is, the bamboo shoot seedlings produced fruit within 6 months after inserting the fruit that can not be expected at all in the intermediate shovel or live breeding (Fig. 3). Red fruit lasted until May 19, 2006, taken January 9, 2006 (Fig. 4). Therefore, it was confirmed that the fruit can be seen 6 months after the cutting of bamboo shoots, and that the fruit can be appreciated more than 6 months from this.

Comparative example  One

On July 14, 2004, the middle shovel was cut to 20 cm length from bamboo shoots, and the middle shovel was soaked in rooting plant hormone, IBA 100 mg / l, IBA 1,000 mg / l, IBA + NAA 1,000 mg / l. Hormonal treatment. For comparison, experiments were also performed on untreated controls that did not receive rooting hormone treatment. The treatment time was 10 minutes at 100 mg / l and 10 seconds each at 1,000 mg / l and 1,000 mg / l of IBA + NAA, followed by vermiculite: Pitmoss on a wood cutting of 1.5M x 1.5M x 0.4M. : Mixed soil of pearlite (1: 1: 1, v / v / v) was filled and a hormone-treated intermediate shovel was inserted. Then, after moisturizing periodically (for example, until water is sufficiently absorbed on the insert once a day), the rooting rate, rooting number and root length of seedlings rooted around December 14 were investigated. It is described in.

In addition, the control group and the hormone-treated intermediate shovel of Comparative Example 1 did not develop a new branch to form a flower bud within one year after cutting and did not have a deletion.

Comparative example  2

After cutting the middle shovel 20 cm long from bamboo shoots on November 25, 2004, the middle shovel was soaked in rooting hormone, IBA 100 mg / l, IBA 1,000 mg / l, IBA + NAA 1,000 mg / l. Hormonal treatment. For comparison, experiments were also performed on untreated controls that did not receive rooting hormone treatment. The treatment time was 10 minutes at 100 mg / l and 10 seconds each at 1,000 mg / l and 1,000 mg / l of IBA + NAA, followed by vermiculite: Pitmoss on a wood cutting of 1.5M x 1.5M x 0.4M. : Mixed soil of pearlite (1: 1: 1, v / v / v) was filled, and hormonal treated intermediate shovel was planted. Then, after moisturizing periodically (for example, until water is sufficiently absorbed on the insert once a day), the rooting rate, rooting number, and root length of seedlings rooted around April 25 were investigated. It is described in.

badge Rooting rate (%) Logistics No. of roots Root length (cm) Vermiculite: Pitmos: Pearlite = 1: 1: 1 Control group (n = 32) 80 8 5.0 Rooton (n = 32) 70 4.2 4.3 IBA 100 mg / l (n = 32) 70 6.3 5.9 IBA 1,000 mg / l (n = 32) 80 9.5 9.3 IBA + NAA 1,000 mg / l (n = 32) 80 4 4.5
In addition, the control group and the hormone-treated intermediate shovel of Comparative Example 2 did not generate a new branch to form a flower bud within one year after cutting and did not have a deletion.

As can be seen from the above Example 1 and Comparative Examples 1 and 2, the rooting rate was 60% to 70% in almost all treatments including the untreated control. Results conducted on November 25, 2004 showed that rooting rates were 70-80% in all treatments. On the other hand, on May 4, 2005, the rooting rate was 100% in all the treatments except the 90% rooting rate of the untreated control.

On the other hand, the material of bamboo shoots on May 4, 2005 was Cheon sho, whereas the materials of the two treatments on July 14, 2004 and November 25, 2004 were medium shovel materials using the middle of the stem. Therefore, it can be seen that the above embodiment obtains the best results by cutting using bamboo cloth shovels in spring rather than hot summer or autumn.

Therefore, the method of propagation of bamboo shoot vinegar according to the present invention enables the flowering of bamboo shoot vinegar in a short time, which can be widely distributed for differentiation or cut flowers, and furthermore, export to Japan where the demand of bamboo vinegar is high and ultimately increase the income of Korean farmers. Will contribute. In addition, it will be possible to select new and superior native species in the indoor landscaping plant market, which is difficult to name.
