Description

Jasenglan Seokgok New Type Snow New {snow plant) {New plant variety of Dendrobium spp. Sul kuk}

The present invention relates to a new breed of native Jalanguk of Oriental eggs, which has a white-yellow fresh-striped pattern with light yellow gloss, light green luster, neat and stable ultrafine, and high ornamental value.

Dendrobium spp. Is a small egg plant that grows on the rocks or trees of eastern Asia, especially Korea, Japan, and China. In Korea, it has a fragrance, strong growth, low temperature resistance, and good resistance to drying.

It is nicknamed as Jang Saeng Ran (長生 蘭) for its horticulture of mutant species with unusual patterns and shapes of leaves and stems and colors and shapes of flowers.

The characteristic feature of the grains is that the leaves are semi-deciduous, less glossy, without pattern, and the stems have nodes and thin and long. Flowers come out from the nodes of Aixa, and bloom in May-June and have a sweet scent.

As such, plants of native Seokgok varieties have no pattern on the leaves and believe that they have low ornamental value and have low palatability, so there is little demand, so the sale is difficult, and the flowers have less fragrance and the flowering time is also very short and moist within 2 weeks (14 days). There was a problem that is very difficult to manage cultivation.

The present invention is conceived in view of the problems of cultivation management according to the disadvantages of the botanical characteristics of the above-mentioned native wild boulder plants varieties and low coronary preference by people. Therefore, an object of the present invention is to provide a new leaf varieties, which have a corrugated value and glossiness on leaves.

Another object of the present invention is to provide long varieties with excellent flowering habit, rich fragrance, and longer flowering period.

Still another object of the present invention is to provide a new breed that has good texture and easy cultivation.

The new plant 'Sulguk' of Jasengran Eggok of the present invention crosses Wando-san's magnetic Seokok on a five-month flowering period, and harvests seeds after four months sowing into a 500 mL triangular flask;

Irradiating the germinated seedlings with 10 GY and 30 GY irradiation doses for 24 hours (dose rate 0.417 GY and 1.25 GY per hour, respectively) at a distance of 270.6 cm and 150.2 cm from the radiation source, respectively;

Selecting the abdominal ring pattern object from the 30GY-treated flask by primary passage and three passages at intervals of 12 to 14 weeks after the radiation treatment;

An asexual breeding step of proliferating and cultivating the seedlings in the abdominal ring pattern object;

Cultivating a greenhouse ring object in a greenhouse;

This was achieved by evaluating the flowering and horticultural characteristics of the new varieties and naming it as Sul kuk.

The horticultural properties of the native jakseok new breed 'Sulguk' of the present invention are as follows.

1) Leaf pattern: fresh stripes, abdominal rings (comparative: native wild gypsum has no pattern)

2) Gloss of leaves (1-9): Good (9)

3) Leaf length: 3.2㎝ (Comparative: 3.8㎝ of native eggs)

4) Leaf width: 1.3 ㎝ (Comparison: native spawn granules 1.3 ㎝)

5) Dyeing: Light green

6) Height: 9㎝ (Comparison: Jasengran Stone Grain 14㎝)

7) Flowering season: 4 ~ 5 months (Comparison: Jasengran Seokgok 5 ~ 6 months)

8) Number of flowering times: 2 times a year (Comparison: Jasenglan Seokgok, once a year)

9) Flowering period: 3 weeks

10) Reproduction method: growth point tissue culture

11) Uses of varieties: ornamental (stone chief, wood chief), eruption

The new varieties of 'Sangguk' of the native Jaguk Seokgok has a pattern of freshly streaks, abdominal rings, and very good gloss of leaves. The new plant of the present invention is a conventional ornamental use, which improves the value of the commodity, and also has a variety of uses for the differentiation for stone or wood for the differentiation that can be sold for decoration because the leaf is dwarf and the shortest and shortest. There is this.

Furthermore, the new varieties of native Jaguk of the present invention Seolguk (雪 國) can see flowers twice a year, including the indigo bloom, and the flowering period is also extended more than one week compared to Jaguk of the native plants new ornamental species Has an excellent effect.

Hereinafter, the present invention will be described in detail with reference to the growing method of the new breed plant 'Sulguk' of native grains.

Example 1 Breeding and Seeding of Native Eggs

'Seokgok' in Wandosan Jeollanam-do (see Fig. 1) was harvested and incubated to induce flowering and artificially crossed in early May 2002, sown in mid-September, and sown in conventional MS medium in a number of 500 mL serious flasks.

Example 2 Selection of Variants after Irradiation and Subculture

In March 2003, the seedlings germinated in the Erlenmeyer flask were divided into two experimental groups (differentiated radiation dose of 10GY and 30GY) to attempt radiation treatment.

Severe flask seedlings in experimental group I were treated with radiation (γ-ray) dose of 10 GY for 24 hours at a distance of 270.6 cm from the radiation source (dose of 0.417 GY per hour),

Triangular flask seedlings of Experimental group II were treated with a dose of 30 GY at a distance of 150.2 cm from the radiation source (the dose per hour was 1.25 GY).

There are a total of six radiation treated flasks, three in each of the experimental groups I and II.

After 2 weeks of radiation treatment, primary passages were performed three times at intervals of 12 to 14 weeks. Abdominal ring-patterned individuals were obtained from a 30GY-treated flask of Experiment Group II.

In Experimental Group I, no variant was found.

Example 3 Proliferation and Culture of Abdominal Ring Pattern Seedling Variants

In order to confirm genotyping and phenotyping of seedling mutants of 'Sukgok' grown native eggs according to Example 1 and Example 2, they were mass-grown and cultured for two years in 2004 and 2005.

Example 4 Pure Greenhouse Cultivation

In early 2006, a cultivation test was conducted for 2,000 strains to confirm that the variant seedlings of the present invention had superiority and uniformity as new varieties.

The seedlings were purified by planting on the 105-hole plug plate in the conception in the greenhouse. After 8 months, the seedlings were transplanted into 5cm pots, and after 6 months, they were transplanted into 8cm pots. In the cultivation management, the temperature in the greenhouse was 22 ° C ± 2 ° C, the humidity was 60-80%, and the brightness was 8,000-10,000Lux.

Example 5 Investigation of Flowering Characteristics of New Solanum 'Suluk'

In order to confirm the flowering characteristics of the new varieties of the present invention, the results of the two years of 2007-2008 survey were as shown in Fig. 3b, and the leaves were shown in Fig. 4b.

The flowering period was once in April-May, and the occasional flowering was once in August-October. The flowering period was more than 3 weeks, and the floral scent was more than 30 times stronger than 'Sukgok' (see Fig. 3b).

Sulkuk is a new type of oriental orchid of the present invention, which has a double ring and luster, and has a high ornamental value. It has excellent flowering habit, a long flowering period, a scent and a strong color, and is excellent as an ornamental product. This is a very useful invention in the horticulture industry because it can increase the demand for differentiation or stone and wood products for easy cultivation management.
