    The invention relates to agriculture, in particular to the vegetative micro-multiplication of plants in sterile tissue cultures.
    The aim of the invention is to increase the efficiency of the method.
    According to the method prototype (option I)
    Amsonia tabernaemon plant stalk
    tana gives for 1 month. approximately 5 side shoots. They are cut off and placed in a solid nutrient medium. After 1 month, they begin to take roots, that is, only one fibril, 5 plants obtained are transplanted finally into the ground.
    For the proposed method, it is characteristic that the sterile
    The cuttings of the plant shoots are placed in a suitable vessel with solid nutrient medium, then the vessel is filled with a nutrient solution containing, if desired, growth regulating substances, and the shoots are left in this submerged system for germination. Arisen branched cultures with axillary buds and lateral shoots are cut into pieces, the apical shoots forming roots form roots by a known method, and after the transition period in the greenhouse, they are planted in the open air,; youngsters obtained from the lower and middle parts the cultures of the shoot, the cult is celebrated again.
    Agar-agar is advisable to reinforce solid nutrient media. A solid nutrient medium provides the plant with essential nutrients. Nutrients are transported through the vascular bundle. A solid nutrient medium is necessary in order for the shoots to be able to adopt a position corresponding to the natural conditions. VIYAM, i.e. Vertical „
    Liquid nutrient solution provides shoot culture with additional nutrient nutrients. “Cultures filled with a non-hormonal nutrient solution containing mineral salts, sugar and vitamins form shoots that are 30–100% thicker and longer than shoots that are immersed in nutrients solution.
    However, plant hormones can also be added to the liquid feed: Of these, mention should be made of auxin, cytokinin-l gibberellin. Of cytokinias, b-benzylaminopurine (6-benzyladenine) was particularly successful. Under the influence of plant growth regulators, there is a massive development of shoots of submerged culture. This development is more intense at about 100-500% than in cultures that have received growth regulator in the main nutrient medium. In a culture filled with Piditol solution with a cytokinin-containing solution, leaf buds form and the top of the shoots form over the entire surface of the submerged part of the plant; even, the newly formed buds continue to branch, further,

    Option II. From the 10-15 year old Amsonia tabernaemontana plants, one instance was selected for the content of biologically active substances with a content of taberzonin 12.26%. In April, shoots 25-30 cm long were cut from the plant. 20 leaves. Then, for better use, the shoots were cut into pieces about 10 cm long and washed for 1 h under tap water. Then the leaves were cut again by about a quarter of their
    15 values, - the parts of the shoots thus cut, were sterilized in a 3% sodium hypochlorite solution for 15 minutes with constant shaking. From a solution of hypochondylorite, tea plants were placed in distilled water, sterilized in an autoclave, and washed with shaking-1 for 10 minutes. This action, as well as the subsequent ones, was carried out under aseptic conditions in a sterile vaccination cabinet. Shoots taken from sterile water were cut with a scalpel in a sterilized, warm piece of Petri
    3Q having 2-3 leaflets each, with a part of the shoot about 1 cm long left under the bottommost leaf. The cuttings prepared in this way were placed in 200 ml glass flasks, each of which contained 100 ml of Murashige-Skuga improved nutrient medium. The medium on Wednesday had the following composition, mg / l:

    When used, it was taken into account that the cuttings were completely in the nutrient medium before the first leaflet. The flasks were kept at a temperature of ZO-PS C while the daily 16-hour artificial light reached an illumination power of 10,000 liters. A week later, leaf buds appeared in the leaf axils, and about 5-7 cm long shoots grew in the axils of the leaf; 10 12 sheets.
     These sterile side shoots were divided and cut into pieces,
    having 2-4 leaves. This seedling was planted in a nutrient medium of the indicated composition to a depth of less than 1 cm (therefore, it is necessary to cut the appropriate length when cutting under the last leaf).
    Then a similar medium was prepared again, but without agar-agar, instead of which 1 mg / l of 6-benzylaminopurine was used. 50 ml of this liquid nutrient solution was poured into each flask with a volume of 200 ml. The% rendered under the nutrient solution, at a temperature of 20–25 ° C, were constantly exposed to illumination with a force of 8000 lx.
    Leaf buds were formed on all the axils of the leaf, from which shoots 5-10 cm long grew within 3-4 weeks. It was characteristic of them that they also formed buds and shoots again. The strongest shoots grew out of a liquid nutrient medium, some of which were found in the air, formed few leaf buds in the leaf axils or no longer formed them. Now culture is shared. Tops of shoots with 5-7 leaves were cut, were placed in a solid nutrient medium, and after 2 weeks, when enough roots were formed, they were planted in the ground.
    Remaining from the lower and middle parts of the culture, they were cut into pieces with 2-4 leaves or 5-10 buds for each. Then they were also put into a solid nutrient medium of the indicated composition and were filled with a liquid nutrient solution containing 1 mg / l of 6-benzylaminoguri to the proposed method. .

    on. Cultures were cultured at 20-25 ° C and constant light with a force / light intensity of 8000 lux for 2-4 weeks. During this time, the lateral shoots grow, branch further, and form new buds. Accordingly, the formed apical shoots are cut and form roots, the rest of the crop is again cut into pieces with buds and shoots.
    The embedded reproduction of tarragon Artemisia dracunculus without) 5 growth regulators (variant III) was studied.
    From an Artemisia dracunculus grown open-air tarragon plant, a variety of Grune Wurre, shoots of about 10 cm in length were cut in June. Shoots were washed for 2 hours under running water, then sterilized in a 3% sodium chlorite solution for 10 minutes, then washed with sterile distilled water for 20 minutes and cut into sterile conditions into pieces about 3 cm long and having 2-4 leaves. These cuttings were put in
    nutrient medium, respectively, version 30 II. However, the nutrient solution did not contain a plant growth regulator.
    Under the action of a liquid nutrient solution, the shoot culture began to grow intensively. The growth of the culture was 2-5 times stronger than the culture without liquid nutrient medium. Cultures are kept at a temperature of 20-25 ° C under constant artificial illumination with an illumination power of 8000 lx. Shoot cultures, which are located in 200 ml flasks and contain 100 ml of the nutrient medium, for 4-5 weeks completely filled with Eo-occupied the air space of the flask. The lengths of 8–15 cm long were 2-3 mm tolgdina, swollen and relatively little branched.
    Shoot cultures were cut into 5Q parts with 2-4 leaflets, suitable for both root formation and cultivation of the following shedding shoots.
    For root formation, the cuttings of the shoots were placed for 24-96 hours in the nutrient medium in accordance with option II, which additionally contains 1 mg / l 2,4-dichloroenoxyacetic acid. The cuttings are then transferred to the culture medium without a regulator.

    growth, where after two weeks, roots of 5-10 cm in length are formed on each cutting as far as 2–5 cm. Plants with formed roots, if it is necessary to obtain material for planting, are contained without liquid nutrient solution.
    However, plants with formed roots can also be placed in a liquid nutrient solution. In this case, simultaneous mass reproduction of the shoot occurs. By systematically repeating the PG1 proposed method for one year, 100,000 plants with roots can be obtained from a single shoot.
    Studied reproduction of Catharantus roseus (vinca rosca) with kinetin was studied. The plants of Catharantus growing in the greenhouse were cut side shoots 10-15 cm long. They were washed for 4 minutes under tap water, then left in a 1% solution of sodium hypochlorite for 25 minutes and then npoi-sterile distilled water for 30 min. Shoots were cut into cuttings with 2-4 leaves and according to the method described in variant II, placed in solid nutrient medium, kept at a temperature of 25-28 ° C and illuminated with 10,000 lux every day for 16 hours. The tops of the cuttings continued to grow, however, on the whole, they did not branch out, and from cuttings obtained from side shoots, two side shoots appeared mostly.
    After 3-4 weeks, lateral shoots that appeared and grown apical shoots were cut and the cuttings were placed in a solid nutrient medium according to variant II. The flasks with the cuttings were filled with 50 ml of liquid nutrient solution. The composition of the nutrient solution corresponded to the recipe indicated in variant II with the difference that the solution did not contain agar-agar, and instead it was kinetin at a concentration of 1 mg / l. In flasks filled with solution, side shoots became 2-3 times thicker than shoots grown on solid nutrient medium without filling with a nutrient solution. The more often the shoots obtained are grafted, the more intense the development of the shoot and the root formation of the apical shoots become better. By systematically repeating the proposed method, approximately 100,000 apical shoots can be obtained from a single single apical shoot for one year.
