A comparison was also made of the negative effects of allelotoxicity of soils and water extracts from these soils on the seed development. From the analysis of the results, it followed that the development of seeds is influenced only by allelotoxins contained in the soil in the immediate vicinity of plants, entering them, apparently, due to exchange sorption. This mechanism of interaction of soil allelotoxins with plants explains well the effectiveness of stimulating pre-sowing seed treatment with sorption preparations, the sorption capacity of which is several orders of magnitude less than the amount of allelotoxins contained in the soil. A comparison was made that effect of sorption-stimulating preparations during the pre-sowing treatment of seeds and when introducing into the soil 30 times larger quantities. It was found that result of the preparations use does not depend on the method of their application, which confirms the correctness of the proposed mechanism of interaction between soil allelotoxins and plants. Results analysis of the introduction into the soil the sorption-stimulating preparations suggested the existence of a microbiological factor in reducing the allelotoxicity of soils, the use of which made it possible to significantly increase the effectiveness of the sorption-stimulating preparations.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86306901","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}

It is shown that for a long time it was the main obstacle to the successful creation of forest plantations in a number of regions of the country, in particular in the Volga region and in the south of Western Siberia. In addition, it is shown that despite this, the definition of what is the center of mass reproduction of the beetle has not been formulated. Previously, various technologies for the protection against beetles were proposed and widely used, which included both the use of chemicals and forestry measures. This led to a significant reduction in the danger from this pest, and since the end of the 20th century, the chamois has ceased to be a significant reason for forestry workers to carry out protection measures. The article shows that currently favorable conditions are again emerging for the beginning of the formation of large foci of this pest. Definitions for such concepts as «center of mass reproduction» and «center of harmfulness» of Melolontha hippocastani are proposed and the absence of modern drugs and technologies for protection against this pest is indicated.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90662958","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 frequency of occurrence distribution of the age and morphostructural parameters (size of the trunk and crown, self-pruning, length of coarse bark, size and number of side shoots, length and life span of needles) of trees is shown. It has been established that pine trees with smaller trunk and crown sizes, worse self-pruning are more common. Greater height and diameter of the trunk, length and diameter of the crown, better self-pruning, a greater length of the coarse bark is observed in the older generation (g2). This is due to the older age of the trees. It has been established that the relationship between the height of the trunk and the age of the trees is higher in the samples of young generative trees. It was revealed that the young generation (g1) has a significantly greater length and mass of cones, the length, width and height of the apophysis of seed scales compared to the older generation (g2).","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79836190","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}

To assess air pollution in Donbass, it is recommended to use the species Ceratodon purpureus (Hedw.) Brid and Bryum argenteum Hedw. to check the accumulation of pollutants in gametophytes and Populus nigra L. on the specific content of the dendroindicator seeds in chalase capillary bristles. The studies were carried out in the the registration sites of the monitoring network in the central Donbass. The plants in the zones of technogenic and particular anthropogenic impacts (industrial enterprises of the metallurgical complex, dumps of coal mines, places of transport load on ecosystems, residential ecotopes) were studied in comparison with the territories of minimal transformation in the zones of the natural reserve fund in the Donetsk region. For the bryophytes of 11 species of the regional natural flora, taxonomic specificity in the accumulation of heavy metals was established, the facts of hyper- and hypoaccumulation in the thalli of bryobionts were noted. Based on the actual accumulation of heavy metals, the facts of the phytogeochemical migration activity of elements in the surface layer of the atmosphere of an industrially intense region were established. Accumulation of heavy metals in bryophytes occurs during precipitation, and in black poplar seeds freely floating in the air, as a result of active capture of dust particles, which causes a difference in accumulation by different phytosubstrates. The facts of the pollen content in other species of poplar fluff have been established, which is also considered in the context of a possible increase in the seasonal allergenic effect in the population.

Techniques for presowing treatment of seeds in order to increase germination energy and germination of seeds are analyzed. A review of literature sources has been conducted to assess the application effectiveness of plant growth regulators in soaking seeds in order to increase their progenity and increase the resistance of seedlings to adverse factors. Soaking seeds does not require much effort and is the easiest way to treat seeds. A review of preparations (plant growth regulators) for seed processing from the «State Catalog of Pesticides and Agrochemicals» showed that mainly preparations are designed to stimulate the germination of seeds of agricultural plants, fruit and berry crops. Research is actively conducted to find effective preparations and their optimal concentrations for the treatment of coniferous seeds. Based on the review of research, a list of effective preparations for the treatment of Scots pine seeds has been established. Along with ready-made preparations of active substances, a promising way to influence the germination of seeds and increase the resistance of emerging plants to adverse factors may be plant raw materials in the form of wood wastes, parts of shrubs and trees, fall, herbaceous vegetation, including weeds, etc. A review of chemical, biological, physiological methods for improving seed quality showed that they can all be effective. The main principle of choosing the method of treating seeds should be the availability, economic feasibility and high efficiency of the preparation and devices.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88233609","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 forest-oriented recultivation seems to be a promising way to eliminate the accumulated environmental damage formed during the development of mineral deposits. It is shown that successful forest recultivation of disturbed lands has local feautures and is associated with the restoration of the structural and functional integrity of landscape and ecological complexes. Pilot work on reforestation on dumps is recommended to be carried out with minimal costs for the technical stage of recultivation. It has been determined that woody plants deposit toxic chemical elements and reduce the level of secondary environmental pollution. The preference for forest reclamation of anthropogenic landscapes is associated with the restoration of their biological productivity and restrictions on the agricultural use of disturbed lands.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81680247","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 study object was pollen samples of woody plant species used in landscaping in Donetsk such as black poplar (Populus nigra L.), white willow (Salix alba L.), horse chestnut (Aesculus hippocastanum L.), Silver birch (Betula pendula Roth). On the studied sites, it has been established that the sterility of pollen grains ranges from 16 to 44 %, and the viability ranges from 49 to 96%, which is a critical indicator indicating the inability to restore reproductive function in some of the studied species. It is statistically determined that the correlation of the studied parameters (selection points, sterility, viability) characterizes the Donetsk agglomeration as an unfavorable environment for plant life. The data obtained indicate a high degree of adaptation and resistance of tree species to technogenic impact. Indicative signs of atmospheric air pollution are determined, which are typical for the Donetsk agglomeration. Under conditions of intense technogenic load, a pattern appears in the quality change of pollen grains forming pollen anomalies. An indicator that characterizes the anatomical and morphological structure of pollen grains can be used in Donetsk conditions as a complement to other characteristics when a significant level of environmental pollution is detected.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84106499","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}
