Genus Suaeda Forssk. ex J. F. Gmel. is one of the largest in the family Chenopodiaceae Vent. (Amaranthaceae Juss.). Its representatives are distributed throughout Central Asia and are found, as a rule, in coastal halophyte communities. Out of 40 Central Asian species, there are 18 species in the flora of Kazakhstan, 15 (83 %) of which are found in the Aral-Balkhash region. Suaeda species are distributed in 5 sections (Schanginia C. A. Mey., Lachnostigma Iljin, Conosperma Iljin, Physophora Iljin, Heterosperma Iljin). The aim of the research was to analyze the features of the morphology of seeds of species of the genus Suaeda of the flora of the Aral-Balkhash region, which includes 5 floristic districts (14 - Aral, 15 -Kyzylorda, 16 - Betpakdala, 17 - Muyunkum (Moyinkum) and 18 - Balkhash-Alakul). Of the 15 species found within the Aral-Balkhash region, seeds of 11 species were taken for comparative analysis of morphological features (Suaeda linifolia Pall., S. paradoxa Bunge, S. altissima (L.) Pall., S. dendroides (С. A. Mey.) Moq., S. arcuata Bunge, S. acuminata (С. А. Меу.) Moq., S. corniculata (С. А. Меу.) Bunge, S. heterophylla (Kar. et Kir.) Bunge, S. salsa (L.) Pall., S. prostrata Pall., S. crassifolia Pall.). A detailed study reveals sectional differences. In this respect, the seeds of Suaeda acuminata differ most clearly from the species of other sections. from the Conosperma section. The species of the Schanginia section have a generally similar granular structure of the seed surface, and the representatives of the Heterosperma section have a point-grid surface of seeds with a flattened edge.

Weeds can grow both on segetal and ruderal habitats, including outside the agroecosystems of farms. Therefore, it is necessary to study their distribution not only in the fields. The purpose of the study is to identify the species composition of weeds and its features in the ruderal habitats of Gatchina (Leningrad Region). Ruderal habitats were monitored, 78 species of weeds from 62 genera and 21 families were identified. Perennial species prevailed in life expectancy. The taxonomic structure of the species composition has been established. Five families prevailing in terms of the number of species and genera are identified. Calculation of occurrence and assessment of its constancy by classes were carried out. The occurrence of the V class of constancy has 7 species, IV class - 10 species, III class - 8 species, II class - 11 species, I class - 42 species. Groups of 25 dominant and 11 concomitant species were identified. The relationship between species compositions of weeds of ruderal habitats of Gatchina and fields of the Leningrad Region was revealed - 55.56 % of weeds dominating in the fields of the region with different occurrence were registered in ruderal habitats.

The article presents the phytocenotic characteristics of the Medicago sativa+Agropyron fragile-Artemisia diffusa pasture variety, which is part of the Medicago sativa pasture type. The studied type of pastures occupies a small territory in the Central-Primorsky and North-Primorsky subdistricts of the Eastern Cliff of Ustyurt (202 hectares). Medicago sativa+Agropyron fragile-Artemisia diffusa pasture variety is located on a gray-brown soils in the Kungrad district, geographical points: Karakuduk, near the well, from the first terrace to the Aral Sea. The total projective cover of the PV is 80%. In the formation of vegetation, a high proportion is assigned to Medicago sativa - 63 %, Agropyron fragile - 25 %, Artemisia diffusa - 12,5 %. It occurs in small spots on the slopes of gorges and dry beds of spring drains. According to the results of the study, we see that due to the arid climate, the eaten part of the forage mass of the Medicago sativa+Agropyron fragile-Artemisia diffusa pasture variety is low and ranges from 0.8 to 1.3 c/ha. According to the yield indicators, this pasture difference can be recommended for use as year-round pastures.

About 80 species of mosses have been identified as part of the bryoflora of dendrological objects of the Tula region. Five species are listed in the Red Data Book of the Tula Region. The share of rare and interesting species varies in individual objects from 7 to 30 %. The largest number of species, including rare ones, were identified in the objects of Ygnyshevka, Yakshino, Dvoryaninovo, as well as in the arboretum of the Krapivensky Forestry College. A high level of species and structural diversity of mosses is noted in objects where there are natural landscapes. In natural monuments, where old-age coniferous crops are protected, the bryoflora is relatively poor. All the studied objects have a high scientific and practical value, most of them are satisfactory and well preserved and perform an important function of preserving the biodiversity of mosses.

The study of the already established introduction populations of medicinal plants in the conditions of the Botanical Garden is relevant for understanding the prospects for further work on the introduction of plants and increasing their species composition. The analysis of the success of the introduction of 75 species of 43 families of 67 genera of the Far Eastern flora was carried out. Of the species represented, 55 % (41 species) are protected at the local level and included in the regional Red Data Books of Rare and Endangered Plant Species of the Russian Far East, 15 % (11 species) are also protected at the state level and included in the Red Data Book of the Russian Federation. All the types presented are medicinal and used in folk medicine; 4 are pharmacopeial. Groups of plants have been identified that, in addition to medicinal, also have food (11 species from 9 families), honey (10 species from 8 families) and decorative value (67 species from 37 families). In the conditions of the Botanical Garden, all the presented species are long-lived, according to the duration of the existence of introduced populations, they are part of the biocollection for more than 10 years; most of the species are 30-40 years old; 69 species (92 %) exhibit introduction resistance, go through all phenological phases of development, form seeds.

The article presents the results of studies of the biomorphological features of promising daylily varieties (‘Carnival Song’, ‘Celebration Song, ‘Coral Beauty, ‘Matinata, ‘Soft Jazz’) in the conditions of the Karshi oasis. Significant differences in indicators were identified. In varieties ‘Heiloon Lace’ and ‘Red Velor, the number of flowers formed in the inflorescence and the diameter of the flower are larger (10.1 ± 0.6 and 11.0 ± 0.4, respectively), while in other varieties this figure is relatively less. In varieties ‘Heiloon Lace’ and ‘Red Velor, the number of buds formed on the rhizomes was less (0.85 ± 0.26 and 1.14 ± 0.14, respectively), while in varieties ‘Banbury Contrast’ and ‘Nile Crane’, which developed fewer flowers (respectively 6.1 ± 0.3 and 8.2 ± 0.4), by the end of the growing season more buds were formed. From this, it is concluded that hybrid lilies with the highest number of flowers have the lowest vegetative reproduction rate.

The restoration process features of Scotch pine (Pinus sylvestris L.) growing in the Krasnoyarsk forest-steppe pine cenoses have been studied. The study purposes included the abundance and vital status investigation of viable undergrowth in pine cenoses both under control conditions and under anthropogenic impact. The restoration study results of pine regrowth by altitude groups and life condition categories are presented. The contribution of the small, medium, and large regrowth categories to the cenopopulation in various phytocenoses was assessed. The regrowth characteristics are given. It has been established that Scotch pine regrowth with “healthy” category, predominates in almost all the studied plantations. The largest amount of dried undergrowth (2.2 thousand pieces/ha) was noted in the control phytocenosis. The proportion of dry and drying regrowth in phytocenoses under anthropogenic impact ranges from 0 to 30 %, but it is 13 % at control one. However, the pine regrowth individuals’ number with “weakened” category is more than 25 %. It is concluded that at the moment the natural Scotch pine restoration under the canopy of the parent stand proceeds satisfactorily both under anthropogenic influence and in control conditions at the Krasnoyarsk forest-steppe.

The main results of long-term research of woody plants in the arboretum of Khakassia are summarized. In steppe conditions, winter hardiness is the main limiting factor for the resistance of new species. The range of plants used in landscaping is insufficient. Tests of plants are carried out in order to develop cultivation technologies for use in landscaping residential territories. Some species are included in the range for use in the biological reclamation of coal dumps. The arboretum has existed for 47 years, contains 345 species, with a life form of a tree - 151 species, a shrub - 174 species and 20 species of lianas. Multi-species collections of the genera Crataegus, Malus, Cotoneaster, Salix, Betula, Juniperus, Rosa and others have been created. Most species bloom and bear fruit, 14.6 % of the observed give self-seeding. The assortment for landscaping has been replenished with 20 new species. They have been tested in an arboretum, adapted, and go through all phase of growth and development. Recommendations on cultivation in new growing conditions have been developed for individual species and genera. For testing, it is necessary to attract modern forms and varieties to replenish the collection and in the future for introduction into production in different areas of the national economy.
