Abstract Clonal micro-propagation ensures the production of genetically homogeneous, healthy virus-free planting material. This kind of propagation is influenced by genetic, physiological, hormonal, physical factors, and plant genotype. To increase the success of the process, it is necessary to optimize the methods of clonal micropropagation. The technology of clonal micropropagation of grapevine using a culture of apical meristems with a size of 0.1-0.2 mm was developed, the scheme of plant regeneration was improved, a new biotechnological techniques were developed for all stages of propagation. A method of processing of meristems with an ultrahigh frequency (microwave) electromagnetic field (EMF) in combination with a narrow-band laser was developed. Method for improving recovery from viral and bacterial infections using the growth regulator Emistim, Salicylic acid, the antibiotics Gentamicin and Cefotaxime was found. A method of water therapy was developed. The optimal parameters of intensity and duration of illumination were established. Ways of adaptation of healthy plants to non-sterile environmental conditions were optimised. Methods of testing of viral infection was improved. Techniques of planting healthy seedlings in film, greenhouses and open ground were developed. The creation of unique basic vine nursery in Ust-Donetsk region was the result of conducted studies.

Abstract The work is devoted to improving clonal micropropagation methods of the genus Rubus representatives. When cultivating R. arcticus L. cultivars, the optimal concentration of 6-benzylaminopurine (6-BAP) was 0.3 mg L−1. Significant effect of FeEDTA concentration in the nutrient medium on multiplication of R. idaeus L. cultivars was established. The interaction of auxin type and plant genotype was revealed during rooting of blackberry cultivars and raspberry-blackberry hybrids. The nutrient medium supplemented with 0.5 mg L-1 indoleacetic acid contributed to the highest percentage of rhizogenesis in R. arcticus representatives (82%). The optimal growth regulator for conservation of raspberry explants was 6-BAP at a concentration of 0.3 mg L-1. One of the most representative in vitro collections of Rubus cultivars has been created.

Introduction. Forest berry plants are popular on the food market and in pharmacy for their high nutritional and medicinal value. Plantations of forest berry plants can proliferate on unused lands, including depleted peatlands. Clonal micropropagation is the most effective method for obtaining large quantities of high quality planting material. Light-emitting diodes are highly effective for clonal micropropagation. The research objective was to study the effect of different spectral ranges on the process of root formation of forest berry plants in vitro. Study objects and methods. The research featured regenerant plants of half-highbush blueberry, arctic bramble, American cranberry, European cranberry, lingonberry, and Kamchatka bilberry of different cultivars. A set of experiments made it possible to study the effect of lighting type on the growth and development of the root system of forest berry plants in vitro using white fluorescent lamps, white spectrum LED lamps, and LED lamps with a combination of white, red, and blue spectra at the in vitro rooting stage of clonal micropropagation. Results and its discussion. The largest number (3.4–14.6 pcs.) and the maximum total length (10.0–156.9 cm) of roots were observed under LED lamps with a combination of white, red, and blue spectra. The effect was by 1.1–2.8 and 2.0–4.5 times higher than in the case of white-spectrum LED lamps, and by 2.3–7.0 and 3.3–14.9 times than in the case of fluorescent lamps. Variety and shape proved to have no significant effect on biometric indicators. Conclusion. LED lamps had a positive effect on the process of rhizogenesis of forest berry plants during clonal micropropagation. They appeared to be more effective than fluorescent lamps. The combination of white, blue, and red spectra increased the biometric parameters of plants at the stage of in vitro rooting.

Introduction. The last decade saw a considerable increase in the demand for European cranberry planting material (Oxyccocus palustris Pers.) among consumers of non-timber forest products. Cranberry possesses high nutritional and medicinal value. Cultivars and hybrids of European cranberry prove extremely productive for plantation growth using the method of clonal micropropagation with revitalized planting material. Study objects and methods. The research featured European cranberry plants of the Dar Kostromy cultivar and its hybrid form 1-15-635. The study focused on the effect of various medications and growth regulators on the biometric profile of European cranberry and its adaptation to non-sterile conditions at all stages of in vivo clonal micropropagation. Results and discussion. During the introduction stage, the highest viability belonged to the explants treated with AgNO3 (95–96%) and Lizoformin 3000 (5%) as the main sterilizing solutions at a 10-min exposure and a 5% solution of Ecosterilizer (1:1) at a 20-min exposure (90–95%). During the micropropagation proper, the number, average length, and total growth of shoots increased as the concentration of cytokinin 2ip in the WPM 1/4 nutrient medium rose from 1.0 to 5.0 mg/L. At the stage of in vitro rooting, the maximal number, average length, and total growth of roots in regenerated plants for both cultivars were observed when Kornerost 5.0 mg/L was added to the WPM 1/4 nutrient medium. At the stage of adaptation to in vivo conditions, Micogel 0.2 mg/L contributed to the highest survival rate (94–100%). Conclusion. During clonal micropropagation in vitro, the biometric profile of European cranberry (Oxyccocus palustris Pers.) and its survival rate under non-sterile conditions in vivo proved to depend on various growth-regulating substances and their concentrations.

The research is devoted to the development of clonal micro-propagation technology of the decorative cereal Molinia caerulea (L.) Moench. The concentration of 2.0 mg /l of cytokinin 6-benzylaminopurine (6-BAP) contributed to obtaining the maximum number of microshoots: 6.3 and 7.9 pcs. on Anderson's and Murashige-Skoog's (MS) media, respectively, which exceeded the control (by 4.7 and 6.3, respectively, with LSD05 = 2.3). The length shoots were observed on hormone-free media, this indicator significantly decreased with an increase in 6-BAP content. On Anderson and MS media with 1.0 mg/l 6-BAP, the shoot length averaged 21.5 and 26.4 mm, respectively, which made it possible to transplant them for rooting, bypassing planting on a medium for elongation. The inclusion of the Siliplant micro-fertilizer in the MS medium at doses of 1.0 and 2.0 ml/l contributed to a significant increase in shoot size, by 16.7 and 10.7 mm (LSD05 = 8.9), respectively, in comparison with the control (MS). It is recommended to use Anderson's medium and 0.5 mg/l of indole-3-acetic acid as a medium for rhizogenesis: after two weeks of cultivation, the regenerants had a standard appearance with developed roots suitable for planting for adaptation. At the adaptation stage, watering the substrate with the biofungicide «Trichoderma veride» according to the instructions and a cereals single spraying with the micro-fertilizer «Siliplant» at a dose of 1.5 ml/l contributed to their 100 % survival rate.

To establish the biological characteristics of growth and development of plants and the formation of planting material of miscanthus under conditions of drip irrigation. Methods. Field, laboratory, visual, measuring, weight, mathematical-statistical. Results. Represented the effectiveness of cultivation of planting material of miscanthus under conditions of drip irrigation without the application of Maxi Marin absorbent and when it is added to the period of planting of the rhizome. High survival of miscanthus plants in transplanting them from growing to open ground is established. In the conditions of drip irrigation it was 4.9% (without absorbent) and 3.3% (for making absorbent) more than without irrigation was. Drip irrigation significantly influenced the plant height and the formation of stems, while the introduction of absorbent was observed only a tendency of increase of these indicators. Introducing absorbent in rainfed conditions has resulted in a substantial increase in the content of free water in the leaves of miscanthus. Drip irrigation has contributed to intensive growth of not only land mass, and the mass of roots that provided a significant increase in the yield of planting material - the rhizome. The average for years of research weight uterine rhizome in drip irrigation was greater in control (without absorbent) by 62.8%, or 917,9 g than the absorbent application, respectively, the 61.8% or 912,7 g compared to irrigated conditions. Conclusions. The use of an absorbent as in rainfed conditions without irrigation, and in drip irrigation did not provide the increase of biometric parameters of the plants, weight of roots and, consequently, the output of planting material - the rhizome. The increase of these indicators was significantly affected only drip irrigation. In drip irrigation without any absorbent and when it is added from one of the ovaries rhizomes obtained mass was 15-20 g in 1.5 and weighing 25-30 g in 1.4 times more compared to the cultivation of ovaries without irrigation.

The paper presents the results of 2018-2019 research on improving the technology of growing planting material of bog cranberry (Vaccinium oxycoccos L.) of Krasa Severa, Severyanka, Virussaare varieties on the basis of in vitro. Studied was the effect of the concentrations of growth regulators in the composition of the nutrient medium according to Anderson's recipe on the reproduction and subsequent rooting of micro cuttings, as well as the duration of cultivation and adaptation of micro plants depending on partial pruning of shoots. It has been established that at the stage of introduction into in vitro culture, sterilization of explants with 33% hydrogen peroxide in an exposure of 5-8 minutes with washing in 5 portions of sterile distillate gives 60-80 % of viable shoots. The optimum phase of plant development for the successful introduction of in vitro culture is the swelling of buds. Cultivation of micro cuttings was carried out in a light room at a temperature of 25±2 °С, a photoperiod of 16 hours. The duration of each subculturing was 30-60 days. For the stage of actual micropropagation on Anderson's nutrient medium, an increase in the dose of cytokinin 6-benzylaminopurine (6-BAP) from 0.2 to 0.5 mg/l and an increase in the duration of cultivation from 30 to 60 days contributed to a significant increase in the multiplication factor on average for the tested cranberry varieties.According to the efficiency of micropropagation, the varieties Virussaare and Krasa Severa were distinguished – 9.3-12.0 pcs/stalk, respectively. At the rooting stage, the use of a root-forming reagent of indolyl-3-acetic acid (IUK) in doses of 0.2, 0.5 and 1.0 mg/l in the composition of Anderson's nutrient medium did not affect the quality of root formation and the length of shoots of Virussaare micro-plants. No significant varietal differences in the root-forming ability of microcuttings were found. The tendency of better rooting of micro cuttings was observed in the Virussaare variety (90.3 %) compared to the Severyanka (85.7 %) and Krasa Severa (79.3 %) varieties. Micro plants of the Krasa Severa cultivar were characterized by the longest shoots, the total number of roots was less, but their length was longer in comparison with other cultivars. For the adaptation stage, a substrate from a mixture of lowland peat and sphagnum moss was used (1:1). The efficiency of adaptation of micro plants of cranberry varieties when cutting the tip of the shoots was 100 %. Pruning of micro plants shoots contributed to the formation of more side shoots and better development of the aboveground part of the plants.

The article presents the results of experimental studies on various propagation methods of the Arctic bramble in the Kostroma region. Industrial cultivation of forest berry plantations is a possible effective solution to the problem of low profitability of using nontimber forest products, reduction of the wild berries resources and their productivity and quality, and reclamation of cutover peatlands. It is advisable to use high-yield varietal planting material to create such plantations. Special attention is paid to propagation and production of healthy planting material using culture of plant cells and tissues. Data on sterilization of explants when introduced in vitro are given. The highest efficiency of sterilization was observed when using a chlorine-free eco-sterilizer (the plant survival rate on the MS nutrient medium was 90–93 %). The effect analysis of the passage number of regenerated plants on the multiplication factor of the Arctic bramble varieties was carried out. The optimal concentrations of cytokinins at the stage of micropropagation are shown. The largest number of the Arctic bramble roots was observed when adding 1.0 mg/L of Indole-3-butyric acid (IBA) and 0.5 mg/L of Ecogel to the nutrient medium. The technological and agrotechnical operations performed during the cultivation of planting material of forest berry plantations are considered. Data on the coefficients of vegetative propagation of plants and their resistance to diseases, yielding capacity, and recultivation of cutover peatlands are given. The best planting material of the Arctic bramble are ball-rooted seedlings. Sawdust and sphagnum were used in the cultivation of this berry on the peatland. The economic efficiency of its cultivation with the method of clonal micropropagation was 358.2 %. For citation: Makarov S.S., Tyak G.V., Kuznetsova I.B., Chudetsky A.I., Tsaregradskaya S.Yu.

In the present investigation, experiment was conducted for in vitro micro-propagation with different concentration of growth regulators in different explants Sprouts and Shoot tips of potato cultivar Kufri Frysona. The maximum survival percentage (40) of sprouts and (100%) of shoot tips were obtained when the explants were surface sterilized with 0.2% bavistin & 0.4% streptocyclin (45minutes) and 0.1% mercuric chloride (60seconds). Sterilized explants were inoculated on MS basal supplemented with various growth regulators and established successfully. The maximum shoot induction (62.5±1.44%) in 11.3±0.33 days and (74.0 ± 2.13 %) in 10.0 ± 0.50 days were reported on medium PM1 (BAP 0.25 mg/l) in sprouts and shoot tip explants respectively. The sprouted explants were further sub-cultured on MS media supplemented with various growth regulator alone and in combination for in vitro multiplication. In Kufri Frysona (11.2) shoots were obtained on MS medium fortified with 0.25mg/l BAP + 0.01mg/l IAA on 42th day of subculture. In vitro rooting was observed on MS basal medium supplemented with 2.0 mg/l NAA in Kufri Frysona after 10 days. Rooted plantlets were successfully hardened in green house using different types of potting mixture and finally transferred to field. The protocol will be very useful for large-scale production of disease free planting material of potato (S. tuberosum) in future.
