The study of wound-healing effect of the gel substances with 2 and 4 % (w/w) concentrations of the dry extracts of the everlasting flowers and of the littlewale leaves in the ratio 1:1 were carried out.It was found that the skin application of the studied gel substances promoted the formation of the structural and functional regenerate in the area of the wound defect. The studied gel contributed to the significant reduction of the healing duration of the full-thickness linear wounds in rats compared to the control group of animals (without treatment) and to the group of animals that received treatment with the reference listed drug. The use of the studied gels, regardless of the content of the plant extracts in them (2 or 4 % (w/w)), was not accompanied by toxic effects.

The results of a comparative study of the influence of mineral and organic fertilizers - N16P16K16, Nanoplant, Hydrohumate, and Ecosil - on the state of the antioxidant complex of early-ripening (Northcountry, Croaton) and mid-ripening (Bluecrop, Northland) varieties of tall blueberries in an experimental culture on a low-lying peat bog in the Central agroclimatic zone of Belarus are presented. A significant dependence of changes in the level of their antioxidant and enzymatic activity on the type of fertilizers and the genotype of plants is shown. In most varieties, the increase in mineral nutrition contributed to an increase in the antioxidant activity level up to 28 %, the most significant when using Nanoplant and Hydrogumate. Revealed a distinct antagonism in changing the activity of peroxidase and catalase, on the one hand, and polyphenol oxidase, on the other: it increases synchronously in the first pair of enzymes to 77 and 30 % in varieties Northcountry, 171 and 152 % in the variety Croaton, 137 and 182 % in the variety Bluecrop and to 122 % of varieties for the Northland, against a preferential decrease in the activity of polyphenol oxidase in 13-55 %.In most cases, the tested agricultural practices have contributed to raising the general level oxidase activity of blueberry fruit. Especially in Croaton and Bluecrop varieties, by 30-310 %, with the highest efficiency of organic fertilizers, especially Hydrohumate. Nanoplant treatments had an inhibitory effect on the general level oxidase activity in Northcountry and Northland varieties and a stimulating effect in Croaton and Bluecrop varieties.

Rhododendrons are some of the most attractive flowering shrubs in the landscape. The article presents the results of studying the common problems of Rhododendron collection in the Central Botanical Garden of the National Academy of Sciences of Belarus, conducted in 2012-2020. There are several diseases and pests that commonly occur on rhododendrons every year. These include powdery mildew (Erysiphe azaleae), fungal leaf spots (Pestalotiopsis rhododendri, Colletotrichum gloeosporioides, Alternaria spp., Sphaerulina azaleae, Phyllosticta concentrica, Phyllosticta rhododendricola), black vine weevil (Otiorhynchus sulcatus), garden foliage beetle (Phyllopertha horticola), click beetle (Hemicrepidius niger), red spider mite (Tetranychus urticae), physiological leaf spots, oedema, winter injury, chlorosis. Less common on rhododendrons are stem diseases (Botryosphaeria dothidea, Cadophora spp., Hymenoscyphus spp.), wilt (Fusarium oxysporum), bud blight (Seifertia azaleae), leaf and flower gall (Exobasidium rhododendri), rhododendron lacebug (Stephanitis rhododendri), greenhouse whitefly (Trialeurodes vaporariorum). There were identified that all evergreen and half evergreen rhododendrons have some resistance to powdery mildew, deciduous rhododendrons are more resistant to fungal leaf spots than evergreens. Damage to rhododendrons by insect pests usually does not cause significant harm but heavy feeding results in an unsightly plants.

The structure of bird population of urbanized areas is determined by the diversity of habitats within the city, the diversity of bird species in suburban biotopes, and regional processes of dispersal of birds closely associated with human settlements. The analysis of the dynamics of the breeding bird species richness in Minsk showed that its formation progressed in different ways. All in all, since 1946, 141 bird species have been recorded nesting (including allegedly) in the territory of Minsk.The breeding bird assemblages is dominated by dendrophilous (45.0 % of all species) as well as wetland and semi-aquatic (29,3 %) bird species, with more than half of all the breeding bird species (50.3 %) associated with trees and shrubs. In different periods, the breeding bird species richness varied, by now, it has noticeably increased (from 77 to 132 species). This happened due to the expansion of the administrative boundaries of the city with the inclusion of bird species of suburban habitats, an increase in the diversity of habitats suitable for bird nesting (for example, the formation of large water bodies) as well as due to active colonization of urban ecosystems by various bird species. At the same time, after 2000, 9 bird species stopped nesting and 17 bird species started nesting. Active processes of synurbization of some bird species on the European continent observed in recent decades have become the reason for the addition of new species to the avifauna in Minsk, although the basis of the current structure of bird population was formed back in 1986–1999. At the same time, the synurbized groups of various bird species may be of autochthonous, allochthonous, or mixed origin.

In the course of the research, the morphological and morphometric characteristics of the seeds of the leaders of the genus Turbinicarpus (family Cactaceae) were studied. The studied taxa were divided into several groups depending on the sculpture of the seed coat and the surface of the epidermal cells of the seed coat: the smooth surface of the epidermal cells and the wrinkled surface of the epidermal cells. Identified signs that can be used as diagnostic for establishing the systematic position of plants.

Polyamidoamine (PAMAM) dendrimers and amphiphilic dendrons are one of the types of nanomaterials characterized by a hyperbranched structure of polymer branches. In the case of dendrimers, the dendrons are covalently linked at the central focal point. In the case of amphiphilic dendrons, dendrons are non-covalently linked by hydrophobic interactions, forming micellar structures. These nanoparticles are widely used in biology and medicine as contrast agents, carriers of drugs and genetic material. Their use in scientific practice requires an understanding of the basic mechanisms of their interaction with membranes – the main obstacle to the entry of dendrimers into the cell. This review discusses the regularities of the interaction of dendrimers and amphiphilic dendrons with lipid membranes. Various models of dendrimer-membrane interactions are described as the basis for the penetration of dendrimers and amphiphilic nanoparticles into cells. Keywords: polyamidoamine dendrimers, amphiphilic dendrons, lipid membranes, cells, antitumor therapeutics, antibacterial agents, diagnostics, genetic therapy.

Problems and prospects of botanical gardens in a changing climate are discussed in the article. An increase in the average annual surface air temperature, changes in seasonal indicators and the length of the growing season require action from botanical gardens. Decisions on the management of natural and man-made ecosystems, with the aim of their conservation and sustainable development, must be taken taking into account the ecological situation. The knowledge and experience concentrated in botanical gardens makes it possible to assess the threats and opportunities for climate change and develop adaptation measures to them. All activities of botanical gardens should be aimed at counteracting climate change, include preventive measures based on the expected plant responses and compensatory measures. Research work in all areas should take into account the situation with changing climatic parameters. Special attention should be paid to endemic rare and endangered species, historical landscapes, and changes in the assortment of resistant species, cultivation technologies, and biological invasions. Botanical gardens must be proactive by providing information, plant materials and technologies for national and global climate change adaptation programs.

The paper presents the original data of the chromosomal and molecular-genetic (by PCR typing) analysis of cryptic species of the genus Microtus on the territory of Belarus. The aim of the study is to perform chromosomal labeling of common vole populations in various localities in Belarus to identify Microtus arvalis s. l. twin species in natural ecosystems. Based on the karyological analysis, 2 representatives of the cryptic group were identified in the study area: the Eastern European vole (2р = 54, NF = 56) and the common vole (2р = 46, NF = 86). Also, to confirm the species identity of the twin species, a molecular genetic analysis was performed by PCR typing. It was established that one studied individual from the cryptic group Microtus arvalis s. l. belongs to the species Microtus rossiaemeridionalis. A fragment of the cyt b mitochondrial gene was amplified in the size of 469 bp in the remaining individuals (n = 105), and a fragment of the cytochrome b mitochondrial gene in the size of 842 was amplified, which indicates that these representatives belong to the Microtus arvalis form “arvalis”. In conclusion, the results of the work done are summed up, and tasks are set for further research of cryptic species of the genus Microtus in Belarus.

The changes abundance zoobenthos at the heated zone and non-heated zone on the different depths in summer and autumn was studying in this article. In the heated zone, the abundance was 1.5‒2 times higher than in the non-heated zone in summer and autumn. The basis of the number zoobenthos was oligochaete-chironomid complex. Number distributions zoobenthos was similar to the heated zone and non-heated zone in the summer and autumn.
