This paper presents the results of a study that was conducted in the Sergiev Posad forestry of the Moscow region forestry Department with the participation of the laboratory of the Department of Forest crops, breeding and dendrology of the BMSTU (Mytishchi branch). This study shows the technology of planting European (Picea abies L.), seedlings in culture, which can significantly increase the survival rate of experimental samples and improve their biometric characteristics: height, diameter of the root neck, weight, and also the anatomical structure of seedlings. The experiments were performed using a low-frequency generator «Rost-Active», the author’s technology pre-sowing treatment of seeds and seedlings by an electromagnetic field, hydrogel (polymer water-retaining agent) and a method of histometric analysis of cross sections of control and experimental stems of European spruce seedlings. The results of the study indicate a clear positive effect of electromagnetic field and hydrogel on the increase in survival of experimental samples of seedlings of common European spruce in relation to the control. Also, the results of comparative histometric analysis indicate the effectiveness of methods for treating pine seedlings with low-frequency EMF and applying hydrogel to the soil.

The results of the study indicate a clear positive effect of the low-frequency electromagnetic field and hydrogel on the increase in the survival rate of experimental samples of European spruce seedlings (Picea abies L.) treated with BOT technology in relation to the control samples. The results of comparative biometric analysis are presented, which prove the effectiveness of methods of processing spruce seedlings with a low-frequency electromagnetic field and applying hydrogel to the soil. The histometric analysis of experimental and control samples of European Spruce seedlings confirmed the positive effect of the low-frequency electromagnetic field on the anatomical structure of the xylem of seedlings treated using the BOT technology.

The results of studies carried out in the Pravdinsky nursery of the Pushkin Forestry Technical Colledge in the Moscow Region and in the laboratory of the department «Forest cultures, selection and dendrology» at the ВMSTU (Mytishchi branch) since May 2015 untill September 2019 are presented. The results of the study confirmed the significant advantage of experimental indicators over the control. Thus, the treatment of seeds and two-year-old seedlings of Scots pine with a low-frequency electromagnetic field using the POSEP technology, in general had a positive effect not only on their survival rate and biometric parameters, but also on their anatomical structure. Based on the results of the studies, it can be ststed that the POSEP technology is an effective method of physical impact on the survival rate and growth increase of Scots pine seedlings.

This work presents the results of a research that was conducted in the Donskoy Leskhoz nursery of the Forestry Department of the Lipetsk Region. The purpose of the research is to determine the effectiveness of the influence of a low-frequency electromagnetic field and the hydrogel “Evabiona” on the survival rate of red oak annual seedlings grown in open ground of the nursery. This research presents the technology for creating red oak planting material with increased survival indices of test samples and their biometric parameters: seedling height, seedling diameter at a root collar, weight of roots and aboveground part in the air-dry condition after drying for 15 days. Treatment of red oak one-year old seedlings with a low frequency electromagnetic field was carried out according to the author’s technology POSEP – pre-sowing treatment of seeds and seedlings with an electromagnetic field. The hydrogel, a polymer water-retaining agent that absorbs and retains a large amount of moisture in the rhizosphere of plants, was applied to soil in the experimental research. The ability of the hydrogel granules to swell-compression improves the structure and drainage of soils, boosting the conditions of aeration and filtration of water, and maintains its waterretaining properties for several years. The research results indicate a clear positive effect of treatment with a low-frequency electromagnetic field and the hydrogel, as there was a significant increase in the survival rate of the test samples of oak seedlings in relation to the control samples. Also within the framework of the research a comparative histometric analysis of cross sections of control and test stems of oak seedlings was carried out late in the growing season at the laboratory of the Department of Forest Crops, Selection and Dendrology of the Mytishchi Branch of the Bauman Moscow State Technical University. The results of this research showed that a low-frequency electromagnetic field and the hydrogel can influence on the anatomical structure of seedlings, improving their quality characteristics. Thus, pre-sowing treatment of oak seedlings with a low-frequency electromagnetic field and the use of the hydrogel showed the effectiveness of these techniques in increasing the survival rate of seedlings and obtaining high-quality planting material of red oak in forest nurseries.

The results of research that was conducted in 2017 in the laboratory of the Department of Forest crops, breeding and dendrology of the BMSTU (Mytishchi branch) and in the Pravdinsky nursery of the Pushkin forest technical College of the Moscow region. The purpose of the study was to determine the effectiveness of the influence of low-frequency electromagnetic field (EMF) on laboratory and ground germination of common pine (Pinus sylvestris L.) seeds with low seeding characteristics. Samples of common pine seeds of the 3rd quality class were selected for the study (collection 2014). The seeds selected for the study were treated with low-frequency EMF using POSEP technology (pre-sowing seed treatment with an electromagnetic field) with a low-frequency generator Rost-Active. One part of the seeds was laid for germination in the laboratory in 4-fold repetition, the other was sown in the sowing Department of the Pravdinsky nursery in 3-fold repetition, control was served by unprocessed seeds. As a result of pre-sowing treatment of pine seeds, laboratory germination exceeded the control by 25 %, and approached the indicators for class I seeds. In the Pravdinsky nursery, the yield of 1-year-old seedlings increased by 16 %, and their height was 47 % higher than the control. The results of laboratory and field studies have demonstrated the high efficiency of pre-sowing treatment of common pine seeds using POSEP technology and its ability to restore the seed quality after long-term storage, increase the yield of seedlings and improve their biometric indicators.
