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.

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.

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.

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 study presents the results of obtaining regenerated plants of asparagus from seeds. Surface sterilizing the seeds by 0,75% sodium hypochlorite for 30 min is effective, during this obtained 83% viable sterile plants. The Murashige and Skoog medium supplemented with 6‑benzylaminopurine (2 mg/L), inositol (100 mg/L) and thiamine (0,4 mg/L) was found to be the best for seed germination. The expediency of using kinetin (1 mg/L) as a growth regulator to obtain a homogeneous plant material was established. The reproduction coefficient was 6,0. Only 11% of the explants formed callus. For the selection needs and production of somaclonal variants, the use of the culture medium with indole-3-acetic acid (0,2 mg/L) and 6‑benzylaminopurine (1 mg/L) is justified. In this condition reproduction coefficient was 3,7, and the level of different intensity callusogenesis was 59%. The rooting of obtained plants was performed in Murashige and Skoog medium supplemented with a half dose of macro- and micronutrients and growth regulators. Rooting frequency was up to 63%. The knowledge of hormonal requirements helps to promote isolated tissue and cells technologies of asparagus with purpose of rapid propagation and obtaining healthy, high-quality planting material.

Abstract The goals set by Russia for the implementation of the Paris Agreement on Climate Change Mitigation, taking into account the absorptive capacity of forests, have become an additional incentive for the creation of carbon-saving forest plantations, while the formation of a voluntary carbon market has made it possible to receive income from the sale of carbon from such climate forest projects. However, in the absence of experience in the implementation of such projects in Russia and the long-term return on investment in them, associated with the specifics of forestry and the existing risks of obtaining the final result, it has become an unattractive activity. This problem can be solved by creating carbon-depositing forest plantations using fast-growing seedlings of planting material obtained by innovative biotechnological methods. The study determined the costs of creating 1 hectare of carbon-depositing forest plantations, forecasting the possible additional income from 1 hectare per year from forest plantations for the implementation of net primary production. It is concluded that even with conservative net primary production and low carbon prices, the use of planting material obtained by in vitro clonal micropropagation when creating carbon-depositing forest plantations will reduce the payback period of climate forestry projects to 5 years.

Seeds of strongly susceptible to AsTV varieties of salad Chameleon and Bouquet were subjected to thermotherapy at different temperatures (37°C, 38°C, 40°C) for a different time interval (1, 3, 5, 7, 10 days) in dry form and when moistened. Marked varietal specificity during germination of seeds after thermotherapy. Thus, the greatest number of seedlings in the emerald variety was obtained after 5 days of thermotherapy (10.0±0), while the Bouquet variety had the best results after 3 days of thermotherapy (9.3±1.2) with moisture. After thermotherapy of dry seeds by 40°C plant material of cultivar Emerald was planted on solid and liquid culture media. The conditions of step sterilization of lettuce seeds for introduction into the culture in vitro were chosen: washing in 96% ethanol, then in 50% aqueous solution of "Whiteness" with the addition of Twin-20, after in sterile distilled water. The nutrient medium for germination of lettuce seeds was used: Gamborg B5 (2% sucrose, 7.0 g/l agar), and the liquid nutrient medium was of that composition. The obtained seedlings were cutted and transferred to medium MS (2% sucrose, 0.1 mg/l ha and 1 mg/l BAP, 3.0 g/l phytogel). The formed shoots for rooting were transferred to the MS medium (2% sucrose, 3.0 g/l phytogel). In the future, lettuce plants will be adapted in vivo and tested for the presence of tomato aspermia virus in the planting material.
