Asia and adjacent regions of Asia, mainly within the Iranian-Turanian floristic region. Species with very large ranges, partially including C. Asia, are not taken into account. 46 species of Central Asian plants are represented in the open ground expositions of the UNN IBBM Botanical Garden, they make up only 4.6 % of the collection of herbaceous introduced plants of the Botanical Garden. More than 70 % of Central Asian plants in the collection are monocots, including 19 species of the genus Allium L. In permanent expositions, most of the plants are grown in rock gardens. The greatest number of problems arose with representatives from Central Asia due to the fact that seeds obtained from different sources often do not germinate. When grown in permanent exposures, a number of specimens of various origins turned out to be unstable, for example: Ixiolirion tataricum (Pall.) Schult. et Schult.f., Rhodiola algida Fisch. et C. A. Mey. Some plants were shortlived, such as those of the genus Juno Tratt. Regularly bloom, bear fruit, grow well vegetatively Gymnospermium albertii (Regel) Takht., Sedum pachyclados Aitch. ex Hemsl., Corydalis nobilis (L.) Pers., Allium aflatunense B.

As a result of expedition works, 24 studied plant communities (with predominance and participation of various Salsola) were described. Communities differed from each other by species composition, which is caused by a variety of combination of habitat factors. The analysis of the floristic composition of the described rommunities resulted in the identification of two groups: 1) rommunities dominated by species of the genus Salsola; 2) rommunities in which the presence of species of the genus Salsola was insignificant. During the research, it was revealed that annual species S. nitraria Pall. and S. tragus L. are well adapted to the habitat conditions of desert and semi-desert regions and it was roncluded that they can be used for reclamation of disturbed lands.","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":"139364301","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 period from the female cone breakout to the formation of the cone with completely closed scales after pollination was 10 days for all ecotypes. The northern and high-altitudinal ecotypes began “flowering” 2 days earlier with the accumulation of the sum of active temperatures of 290 °С than the southern and low-altitudinal ecotypes, which needed an accumulation of 400 °С for this. The greatest contribution to the ecotype differentiation in female reproductive phenology was made by differences in the timing of the receptive cone stages. The transition to the receptivity stage in the northern ecotypes occurred 3 days earlier than in the southern ones, and in the high-altitudinal ones 2 days earlier than in the low-altitudinal ones. In latitudinal ecotypes, cones were receptive for 2-3 days, in high-altitude ecotypes 1.5-2 times longer. The peak of pollen shedding in each ecotype basically corresponded to the timing of the beginning of the female cone scale opening, sometimes it was slightly ahead of it.","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":"139363604","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 objects of research were 3 wild species of Iris L., growing in the southeast of Kazakhstan. The goal of this research is a comparative anatomical and morphological study of the roots of species Iris alberti Regel (1, 2 populations), I. pallasii Fisch. ex Trevir., I. sogdiana Bunge from natural populations of southeastern Kazakhstan. Field studies of wild populations of the Iris species were carried out by the route-reconnaissance method. Geobotanical methods were used to describe plant communities with the participation of research objects. Microscopic studies of the roots were carried out by conventional procedure. As a result of the anatomical and morphological study, we found that pronounced mesophytic features of the anatomical structure of the plant species are associated with an increase in the diameter of the central cylinder and the diameter of the xylem vessels. The highest degree of development of conducting tissue indicates an increased moisture gradient. The pronounced thickness of the primary cortex indicates the presence of xerophytic features of the anatomical structure. These results indicate the relationship between the ecological conditions of the studied Iris species growth and features of a primary anatomical structure of its root.","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":"139363700","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 article deals with the main patterns of vegetation distribution on the landscape-ecological profile, which covers the eastern spurs of the Chu-Ili Mountains, the sand desert Taukum and the Bozoi plateau located between them. The territory has not been covered by geobotanical studies for a long time and there is no up-to-date data on the state of vegetation. According to the results of our study, the consequences of anthropogenic influence on the composition and structure of plant communities associated with landscape formations of various genesis are described. The series of digression of zonal plant communities under the influence of grazing have been revealed, which differ in different segments of the profile depending on soil conditions. The final stages of digression are completed by the catacenosis of the annual saltwort Ceratocarpus arenarius and sparse communities of perennial herb Peganum harmala in the low-mountain and foothill sections of the profile; in the Taukum desert - by communities of wormwood (Artemisia scoparia).","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":"139363717","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 date, with the development of motorization, the use of reagents for the maintenance of the road network and the conduct of acaricide treatments in squares and parks, a significant difference has formed in the growing conditions of balsamic poplar crops. Biomonitoring of the state of the environment was carried out at three fundamentally different sites in Novosibirsk. Evaluation of the fluctuating asymmetry of balsamic poplar leaves showed that ordinary plantings along the road network are characterized by a high deviation from the stability of development. Forest crops of balsamic poplar in urban forests are characterized by the presence of deviations from the stability of development. The best indicators were obtained for balsamic poplar plantings in landscape groups in the park - the presence of a weak deviation from the stability of development. The best indicators were obtained for balsamic poplar plantings in landscape groups in the park - the presence of a violation of the stability of development. To date, 50-70-year-old balsamic poplar crops grown on the territory of the megalopolis are characterized by varying degrees of disturbance or deviation from the stability of development.

Seed dormancy is the center of the so-called “thermal memory”, playing a key role in the acclimatization of plants to the seasonal climate. By saving information about the past temperature conditions of the species existence, the seeds manifest a high degree of heterogeneity in depth and type of dormancy, which varies depending on the location of the seed in the fruit and the fruit on the inflorescence, seed size, altitude and latitudinal areal of plant populations, weather conditions for seed maturation and preservation in soil. The high degree of plasticity of dormancy state requires different approaches to the study of this problem. In this regard, the article gives a number of recommendations for carrying out experiments and using special methods. One should take into account the areal of the species, the weather conditions for seed maturation and the periods of seed dry storage. Factors such as temperature and illumination should be applied in a differentiated way that permit to reveal the individual mechanisms of the initiation and removal of dormancy. The use of different methods -monitoring of seed germination, the culture of isolated embryos, cytoembryological study - makes it possible to assess the internal state of the seed and the localization of the mechanism of inhibition of post-development and germination of the embryo.","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":"139364028","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}
