The paper presents the research materials of Korean cedar introduction in the forest-steppe conditions of Voronezh region. Full compliance of its vital processes with the conditions of introduction is determined. The influence of the factor of tree placement in the territory — free or as part of other conifers on seed production — has been established. The increase of trees yield was revealed when artificial pollination was applied to them in comparison with non-pollinated trees. Attention was drawn to the moment of formation of multi-top tree crowns by formation of «empty» cone at the top of the central conductor. The high perspectivity of the breed cultivation in these conditions with obtaining both silvicultural and economic effect is pointed out. The forecast of yield of Korean pine crops under certain conditions of technology is given. Taking them into account in the creation of Korean pine seed object from 1 hectare of cultivated area it is possible to obtain the yield from the moment of grafting age in 25 years in the amount of 123 kg of nuts.

The study results on the oil pollution biodegradation at technogenic entities (oil depots) of various climatic zones in Yakutia are presented. All the studied territories are characterized by a perennially frozen rocks, however, various mechanisms of oil pollution biodegradation of the soils in these territories have been established. It is shown that the degradation mechanism of oil pollution depends on climatic conditions, and a temperature is the main factor affecting the activity of soil microflora and its diversity. It has been established the oxidative degradation of oil pollution in the temperate zone with a sharply continental climate runs mainly due to biodegradation processes, and in the Arctic zone it is carried out under the influence of physical and chemical environmental factors. In Arctic soils biodegradation of oil pollution occurs by decay. As a result, the soils begin to colonize putrefactive and pathogenic microorganisms. It is recommended to carry out research on the development of effective methods for cleaning Arctic soils from oil pollution.

Cryo-scanning electron microscopy was used to study the micromorphology of the leaf surface of the wild-growing Cydonia oblonga Mill. (Rosaceae). The only habitat of wild-growing quince in Russia is the southern part of Dagestan. Mountain forest phytocenoses of Dagestan provide unique grounds for studying the adaptive potential of plants, since growing conditions change not only according to the change of seasons, but also directly depend on the altitude above sea level. The adaxial (upper) and abaxial (lower) surfaces of the studied samples have a number of micromorphological and microstructural features. The epidermis on the adaxial and abaxial sides differed not only in structural organization, but also in the specifics of surface micromorphology. The most striking feature of the micromorphology of the adaxial and abaxial sides of the leaf blade surface is cuticular folding in the form of microstrands on the main cells of the epidermis, as well as radial striations, peristomatic rings, and protrusions in the stomata region. Regardless of the habitat of fruit plants, their leaves were hypostomatous with anomocytic stomata of two types (primary and secondary), differing in qualitative and quantitative indicators. The primary stomata had a more prominent cuticular pattern and were also larger than the smaller secondary stomata. It should be noted that the presence of several types of cuticular folding, as well as stomatal polymorphism, are common features of other studied species of the subfamily Pyrinae, early Maloideae (Rosaceae). According to the data obtained, the identified features of cuticular folding are stable within the species and can be used as additional taxonomic characters.

The paper presents the study results of the atmospheric carbon deposition by the main forest-forming coniferous species, namely European larch and Scots pine, in two forest monitoring sites represented by 100-year-old forest plantations on the territory of the Nikolskaya forest dacha (north-east of the Moscow region) under typical conditions of native fresh blueberry pine forests (B2). It was analyzed that the forest plantations of European larch in terms of the total phytomass of the trunk significantly exceed that of forest plantations of Scots pine, where it turned out to be 34 % less in the latter than in the artificial larch stand; in the total phytomass of the trunk, the proportion of the larch bark fraction was 13,2 %, and in pine cultures — 7,6 %. A clear advantage in carbon deposition of European larch over such a native species as Scots pine was determined, which is actually expressed by a twofold excess in accumulated carbon, which indicates a highly desirable use of European larch as a valuable introduced species for the creation of forest plantations. It has been established that the climatypes of the genus Larix in the geographical plantings of the mixed forest zone, represented by European, Polish and Sukachev’s larch, achieve the maximum silvicultural effect. It is concluded that the deposited carbon correlates with the phytomass of the forest stand, which, in turn, correlates with the stock of stem wood. Knowing the stock of stem wood, to a certain extent one can consider the stock of deposited carbon.

The article presents the results of testing two different types of pheromone traps for catching a dangerous quarantine pest — the brown marmorated stink bug Halyomorpha halys in the North Caucasus conditions. The data showed that the use of a small (hanging) accumulative pyramid shaped trap in hazelnut planting allowed increasing the catches of adults of Halyomorpha halys by 94 % and nymphs by 75 %, in comparison with a large (ground) accumulative pyramid shaped trap. During the trial, the conditions under which the pests nymphs and adults were actively caught in pheromone traps were determined. The main catch of nymphs — 83 % was fixed at temperatures from +20 to +25 °C, while 52 % adults — at +25...+ 30 °C. The percentage of adults and nymphs of the brown marmorated stink bug caught in the traps was about the same level and amounted to 53 % and 47 %, respectively.

Decorative types and varieties of trees and shrubs have long been widely used in the practice of gardening and landscape construction. Significant enrichment of the range of urban green spaces is possible due to the introduction of introduced plants. The arboretum garden is studying the possibility of growing non-district rocks in specific soil and climate conditions and selecting promising species for gardening, which will create valuable introduced objects. The processes of plant growth and phenological development are analyzed in detail. In this paper, tree and shrub species that grow on the Northern and southern borders of their introduction within the Russian Federation are selected. Observations were made in dendrological gardens in the cities of Arkhangelsk and Sochi. The phenological dates of seasonal development of these species are established and recommendations are given for the use of the studied introduced species in the urban greening system. It is established, for example, that Hungarian lilac grows successfully and bears fruit on the Northern border of introduction and has a winter hardiness score of I, while in subtropical climate this species, although it forms generative organs, has a depressed state. Western thuja in the conditions of Arkhangelsk does not bloom and does not bear fruit, it dies out in severe winters. On the southern border of its introduction, it is widely used in the urban greening system and in topiary art. The correct selection of species on the introduction site will allow you create a highly decorative, aesthetically charming, recreational-attractive, health-improving plantings.

The article presents the resistogram analysis results of the healthy and damaged pine trunks with the systematic resistance error identification to drilling of pine wood when using the resistograph. The influence of the bore drilling channel length on the amount of resistance to drilling of pine wood has been established. It is indicated that when using resistograms as an express method for assessing the quality of wood trunks, it is necessary to adjust its dataset. A method of modeling the effect of the trunk drilling depth on the amount of resistance to wood drilling is proposed. The influence of the bore drilling channel length on the value of the systematic error of the resistance to pine wood drilling was revealed. The systematic error of pine wood drilling resistance depends on the number of the drill bit working cycles. When the number of work cycles is up to 100, the systematic error is up to 20 Resi; from 100 to 200 — from 20 to 60 Resi; more than 200 — from 60 to 200 Resi. When using a drill bit after 100 working cycles, a linear dependence of systematic errors of resistance to pine wood drilling on the length of the bore drilling channel is noted.

The study of the test crop European birch elevated phytomass at the magnesite production impact zone (the Southern Urals, Satka) was carried out. Two plots of test crops of the same age (created in 1983) growing 3 km away from the source of technogenic pollution from magnesite production and with different soil fertility were studied. The elevated phytomass of the stand was calculated using sample trees. The selection of trees was carried out from different thickness levels within the entire range. A regression method was used to estimate the phytomass of the stand. In the course of our work, we tested the null hypothesis that soil fertility is a significant factor for the adaptation of the Betula pendula Roth to pollution since it was noted that stands on rich soils have the best growth (height, diameter) and the vital condition of the stand. A comparative analysis of the elevated phytomass of test crops with the same level of pollution by magnesite production emissions, but growing on soils of different fertility, allowed us to assess the effect of the soil factor on the ability of the European birch to adapt to technogenic pollution. Under the conditions of magnesite production emissions, the elevated phytomass of experimental Betula pendula Roth crops growing on highly fertile soils is not reduced to the same extent as that of birch growing on low-fertile soils. Under the negative emissions impact, the mass of wood and branches of the Betula pendula Roth growing on highly fertile soils decreases to a smaller extent than the mass of other fractions. The wood and branches weight of the Betula pendula Roth growing on highly fertile soils is 3.8 and 3.0 times higher, respectively, and the weight of leaves and bark is 2.3 and 2.4 respectively, compared with test plot No. 5 on low-fertile soils.

The wood and branches weight of the Betula pendula Roth growing on highly fertile soils is 3.8 and 3.0 times higher, respectively, and the weight of leaves and bark is 2.3 and 2.4 respectively, compared with test plot No. 5 on low-fertile soils.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78476837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most important meaning of color in landscape art as a tool for harmonizing the spatial structure of public spaces and its application pecularities are considered. The outstanding masters’ experience of the past and modernity is analyzed. The compositional principles of the space components interaction using color and light, climate, shape, material, texture, vegetation are considered. The actual methods of applying color in practice from the semantic component to the coloristic solution in the form of contrast and nuance as expressive means are characterized. A study of the psychological and physiological effects of the color palette on the human senses was made. Recommendations are given for creating a comfortable attractive public space through the competent use of color as an art and science. Thus, the correct science-based color harmonies and landscape-visual design of objects are created.
