The article presents the results on selection of optimal concentrations of nutrient media components and nutrient solution at the stages of clonal micropropagation of potato varieties Lyubava, Kemerovochanin, and Tuleevskiy (actual reproduction, rooting in vitro, adaptation to ex vitro conditions). The influence of some components of the nutrient medium (sucrose, agar-agar, growth regulators, namely α-naphthyl acetic acid, β-indolyl acetic acid, and β-indolyl propionic acid) was studied at the stages of reproduction and rooting in order to obtain regenerants of the studied potato varieties. The best development of plants on nutrient medium with addition of 4 g L-1 of agar-agar was revealed. The addition of sucrose in the concentration of 3-5% contributed to the formation of more internodes. The influence of naphthyl acetic acid, β-indolyl oil, and β-indolyl propionic acids in different concentrations on the rhizogenesis of regenerating plants of three potato varieties at the stages of reproduction and establishment of different types and concentrations of auxins was studied. The researches have shown that a one-stage method of adaptation of Solanum tuberosum L. varieties of Lyubava, Kemerovochanin, and Tuleevskiy to the conditions of ex vitro cultivation with the use of hydroponic installation is characterized by efficiency and allows to receive plants with well-developed root system. The efficiency of using the hydroponic plant for adaptation of potato regenerants at the final stage of micropropagation is shown.

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 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 growth and development of lingonberry (Vaccinium vitis-idaea L.) plants propagated either by conventional softwood cuttings or by in vitro shoot proliferation from nodal explants and by shoot regeneration from excised leaves of micropropagated shoots, were studied in cultivars `Regal', `Splendor', and `Erntedank'. Significant differences were observed between the treatments. After 3 years of growth, the in vitro-derived plants produced more stems, leaves, and rhizomes than the conventional cuttings which rarely produced rhizomes. In vitro culture on nutrient medium apparently induces the juvenile branching characteristics that favor rhizome production. This increase in vegetative growth and rhizome yield of in vitro-derived plants over stem cuttings varied among genotypes.

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.

Mahonia ‘Soft Caress’ is a unique new cultivar exhibiting a compact form and delicate evergreen leaves. Protocols for micropropagation of M. ‘Soft Caress’ were developed to expedite multiplication and serve as a foundation for future work with other taxa of Mahonia Nutt. Combinations of sucrose at 30 or 45 g·L−1 in conjunction with Gamborg B5 (B5), Quoirin and Lepoivre (QL), and Murashige and Skoog (MS) basal media as well as other selected growth regulator treatments were evaluated as multiplication media. Rooting of microcuttings was conducted in vitro using combinations of indole-3-butyric acid (IBA) at 0, 2, 4, 8, or 16 μM under either light or dark. Quick dip treatments with aqueous solutions of the potassium (K) salt (K-salt) of IBA at 0, 5.2, 10.4, 20.7, or 41.4 μM were tested in a second experiment for ex vitro rooting. Media containing B5 basal salts and vitamins supplemented with sucrose at 30 g·L−1, 5 μM 6-benzylaminopurine, 5 μM kinetin, 0.5 μM indole-3-acetic acid, and 2.5 μM gibberellic acid yielded 2.80 ± 0.14 microshoots with a mean length of 14.76 ± 0.63 mm over a 6-week culture period and was an optimal multiplication media. Light treatment and IBA concentration had a significant effect on rooting percentages. Microcuttings treated with 8 μM IBA and maintained in the dark resulted in the best rooting (70%) and ex vitro establishment.

Two different methods of in vitro multiplication of Rauwolfia serpentina from nodal explants were compared viz. multiplication via callus morphogenesis and that via shoot proliferation from axillary buds. The second method was found to be far better. The optimum shoot proliferation occurred on Murashige and Skoog (MS) medium supplemented with 1 mg/L naphthalene acetic acid (NAA) and 2 mg/L of benzyl aminopurine (BAP). The best rooting of shoots occurred on MS medium containing 4% sucrose and 1 mg/L of NAA. Solid and liquid MS media were found to be similar in supporting shoot proliferation. The plants produced were successfully hardened and established in soil. An easy, reliable and reproducible protocol was developed for in vitro micropropagation of Rauwolfia serpentina from nodal explants.

Work on the clonal micropropagation of strawberries comes down to the search for new growth regulators, which include a biologically active substance - the waste product of the wax moth Galleria mellonella L. The effect of the waste product of the wax moth on the efficiency of clonal micropropagation of strawberries (Fragaria х ananassa duch) in vitro and in vivo conditions in 2018-2020 is shown. The object of research is micro-cuttings, rooted micro-cuttings and adapted micro-plants of garden strawberries of the Korona variety and of the remontant strawberries of the Brighton variety. It was revealed that at the proliferation stage, the propagation coefficient of the Korona variety increased significantly with the introduction of the waste product of the wax moth in doses of 4.0 mg/L and 6.0 mg/L and amounted to 4.2 and 3.8 pcs./explant, respectively; for Brighton variety, the coefficient increased significantly when the dose of the waste product of the wax moth 2.0 mg/L and amounted to 4.6 pcs./explant. The introduction of the waste product of the wax moth in doses of 4.0 mg/L and 6.0 mg/L into the nutrient medium had a significant effect on the yield of Brighton micro-cuttings suitable for rooting: the yield was 95.5 and 94.1%, respectively 87.7% in the control. For the Korona variety, no significant positive effect of the waste product of the wax moth on this indicator was noted. The rooting of micro-cuttings of strawberries of both varieties significantly increased with the introduction of the waste product of the wax moth into the nutrient medium in all studied doses and amounted to 86.4-100% in the Korona variety, and 88.9-100% in the Brighton variety.  The survival rate of adaptable micro-cuttings of Corona variety strawberries when sprayed with an aqueous solution of the waste product of the wax moth at a dose of 4.0 mg/L was 100%; the maximum survival rate of micro-cuttings Brighton variety is 99.8% in the variant with spraying with an aqueous solution of the waste product of the wax moth at a dose of 6.0 mg/L.

The results of studies on the influence of the nutrient medium and photoperiod on tuberization of micro-plants of promising potato cultivars in an in vitro culture under are presented the conditions of a potato renewal laboratory at the Udmurt Research Institute of Agriculture of the Udmurt Federal Research Center of the Ural Branch of the Russian Academy of Sciences in 2018. Two experiments were carried out to identify patterns of the influence of potato cultivation conditions in vitro on the efficiency of its propagation and to develop an improved method for propagating potato micro-tubers in vitro. The experiments were carried out in accordance with the recommendation “New technologies for the production of healthy source material in elite potato seed production”, “Technologies for microclonal propagation of plants”. Object of research: micro-plants of potato varieties Alena, Charodei, Nayada. The studied variants of sugar concentration are 0%, 2% (control), 4%, 6%, 8%, 10%. The studied photoperiod options are 16 hours (control), 14 hours, 12 hours, 10 hours, 8 hours, 6 hours, 4 hours. Based on the results of studies in 2018, experimental data were obtained. It was revealed that the lack of sugar in the nutrient medium negatively affects the growth and development of potato micro-plants. An increase in sugar concentration to 6–10%, in comparison with the control (2%), significantly increases the tuber-forming ability of micro-plants by an average of 6.1–7.2% and increases the number of tubers from one micro-plant. The highest yield of micro-tubers from one micro-plant on average for varieties was obtained with a 14-hour photoperiod and amounted to 1.3 pcs. With a 12-hour photoperiod, micro-tubers begin to form 7–14 days earlier than in the other variants of the experiment.
