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.","PeriodicalId":508495,"journal":{"name":"Проблемы ботаники Южной Сибири и Монголии","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139364114","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}

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.","PeriodicalId":508495,"journal":{"name":"Проблемы ботаники Южной Сибири и Монголии","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139364317","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}

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.

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 %.

Some species are included in the range for use in the biological reclamation of coal dumps.

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.","PeriodicalId":508495,"journal":{"name":"Проблемы ботаники Южной Сибири и Монголии","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139363492","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}
