Abstract

The present invention relates to an asexual propagation method of Korean fir by interspecific grafting, and more specifically, to an asexual propagation method of Korean fir by interspecific grafting, the method comprising the steps of: performing grafting using fir as a rootstock and a branch of Korean fir as a scion; wrapping and binding the grafted tree and the rootstock using a film; installing a vinyl greenhouse on the grafted tree to maintain the humidity, after grafting; removing the vinyl greenhouse after the mid-June, and then removing branches coming from the rootstock (fir); raising the seedling of objects, which are successful in grafting, for 2 years in the vinyl greenhouse; and transplanting the seedling outside, and performing an acclimation procedure. The grafting technology of the present invention has a high grafting success rate of Korean fir, and thus can propagate and conserve superior objects of Korean fir.

Description

[0001] The present invention relates to a method of silk propagation using a grafting technique,

The present invention relates to a method for silent propagation using the interspecific grafting technique of coniferous trees. More specifically, the present invention relates to the development of a breeding technique for the mass production of Korean native tree species, which is a Korean species species, by utilizing the technology of crossing between fir and conifer trees.

Abies koreana is an evergreen coniferous tree belonging to the family Pinaceae Genus Abies with fir, and the name of the country is derived from the word 'kusal', which refers to a sea urchin covered by long thorns in the Jeju dialect. These species are Korean special species distributed all over the world. They are mainly distributed over 1,300m above sea level in southern part of Korea including Halla Mountain. The tree has a life span of about 100 years and grows like a cool shade when it is young, but likes sunlight when it grows. It is a very popular species because it has a small adaptability to the environment, but its shape is beautiful, its fragrance is good, and the texture of branches and leaves is so soft that many varieties have been developed and used for parks, memorials and Christmas trees. Lumber is used as building material, equipment material, soil wood, pulp material, and is also used as a garden or a Christmas tree.

Artificial reproduction is mainly done by collecting seeds, storing them, and sowing them. The seedlings that grow in this way are weak in dressing bottles, so they must be disinfected in the soil before sowing, and should be made in the shade.

As a conventional technique related to grafting, Korean Patent Laid-Open No. 2001-0074114 (Cut-in Grafting Method) is a semi-automatic method of grafting a grafted graft, At the same time, by the cutting blade, the hypocotyl is cut with a slope, and the hypocotyl of the tree is incised at an appropriate depth so as to be inserted. Utility Model No. 1999-0027751 (automatic cutter for receiving fruit and vegetable seeds) standardizes and automates the cutting of the acceptance neck for the production of grafted seedlings. However, these prior arts relate to a grafting machine and have a different technical structure from the present invention.

At present, conifer trees have been declining due to climate change since 2000, and distribution area is gradually decreasing. In addition, the International Union for Conservation of Nature (IUCN) is urgently required to take measures such as conservation methods and propagation methods, such as evaluation of the Korean native species, coniferous tree, as endangered species (EN).

However, it is disadvantageous that the productivity of seedlings (seedling reproduction) seedlings by seeds is very variable depending on the seed status such as seed fidelity and germination rate, and is weak in dressing seeds and root rot disease at seedling growth and very slow growth. Also, according to the characteristics of the original tree, which is adapted to the highlands, the trees thus produced have a characteristic of failing to adapt when they are planted in lowlands. On the other hand, there is a disadvantage that the growth rate by cutting is different according to the state of the cutting, and the initial growth is slow. As described above, there has been developed a technique for the propagation of the sphincter, but there has been no development of a method of silk propagation such as grafting to overcome such disadvantages.

The present invention is to develop a silk propagation technique for solving the above problems in mass production of conifer trees.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to overcome the limit of reproductive growth using seeds and to be able to adapt well to lowlands, We have developed a cross - grafting technique for fir and coniferous trees.

In this study, we used Abies holophylla seedlings of 3-6 years old,

The receptionist uses the native tree or the conifer tree growing in the field,

The grafting is carried out in the greenhouse (greenhouse or glasshouse) from April to April,

The humidity in the greenhouse is maintained at 50 to 85%.

The grafting technique of the present invention showed a success rate of 88.2%, which is a success rate of grafting with coniferous trees, and provides a method of propagating and preserving to cope with the loss of coniferous trees and efficient supply of excellent varieties.

Fig. 1 shows a dissimilar graft between a coniferous tree (upper) and a fir (lower).
Fig. 2 shows a successful grafting entity.
Fig. 3 is a globular tree grafted with completed grafting.
Fig. 4 is a coniferous tree transferred outdoors five years after the grafting.

The present invention relates to a method for producing a grafted graft, which comprises a step of grafting a fir as a tree, a grafting of a grapevine tree with a graft, a step of wrapping grafts and grains using a film, , Removing the greenhouses from the middle of June and removing the branches from the rootstock, and succeeding grafts have been cultivated in the house for two years, and the seedlings are transferred to the outside to undergo the adaptation process The present invention relates to a method for silent propagation using a seedling-to-seed graft technique.

≪ Example 1 >

In order to solve this problem, the method of grafting of fir and coniferous trees was used as a method of grafting four - year - old fir seedlings and accepting coniferous tree branches. In the middle of March, the leaves of the area to be grafted were taken and grafted. The grafting method uses halting among the general grafting methods. It is a method of splitting the fir (tree) vertically and inserting the refined reception (the tree trunk) to bind. Bonding and grafting were carried out using parafilm. The grafting was carried out in the greenhouse in mid-March, and after the grafting, the small greenhouse was re-installed on the graft to maintain the humidity (over 70%). After mid June, we removed the vinyl house and removed the branches from the fir. Successfully grafted individuals were cultivated in the house for two years, then transferred to the outdoors and adapted to the adaptation process.

≪ Example 2 >

The same procedure as in Example 1 was carried out except that one side of the tree was cut vertically and the receiving side was inserted and then joined.

According to the present invention, it is possible to provide a method for proliferating excellent individuals having a phenotype with high economic efficiency, which can be propagated and preserved so as to cope with the loss of the conifer tree in the future due to a high success rate.
