In the conditions of the VILAR Botanical Garden, all phenological phases are observed. However, the onset of generative phases in Anemarrhena asphodeloides occurs a month later than in nature. So, flowering does not begin in June, but it occurs in the second half of July. The beginning of seed ripening is noted not in August but at the end of September. In addition, plants of Anemarrhena asphodeloides during introduction (zone of excessive moisture) reach a greater height (up to 120 cm) than in natural dry conditions (up to 100 cm). It is shown that during spring sowing, Anemarrhena asphodeloides individuals finish their vegetation in the first year of life in the rosette phase with a height of 12.8-25.7 cm (3-8 leaves). In the second year of life, the generative phase is observed in 62 % of individuals, and in the third year it occurs in 64.5 % of specimens. The average weight of air-dry rhizomes with roots is 14,9 ± 3,5 g/individuals in three-year-olds, and 18,4 ± 4,1 g/individuals in four-year-olds.","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":"139363533","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}

Every year hundreds of thousands of tons of pollutants, including heavy metals, get into the atmosphere, soil, water and other environmental objects. Heavy metals enter the human body with plant products and poison the body. Heavy metals from the environment migrate to plant organs and tissues. It is necessary to find ways to detoxify soils from heavy metals. The article presents the results of the experiment at the biopolygon of the Federal State Budgetary Educational Institution of Higher Education Krasnoyarsk Agrarian University.

The purpose of the selection study of Phlox paniculata in the Siberian Botanical Garden of Tomsk State University is to obtain new highly decorative varieties that are resistant to the conditions of the subzone of the southern taiga of Western Siberia. The production of hybrids has a significant scientific basis and is the result of many years of studying reproductive biology, ornamental characteristics and resistance of varieties. To obtain hybrids in the Siberian Botanical Garden, directional crossing of varieties, obtaining seedlings from seeds with free pollination for collections and in a limited group of varieties, and selecting «random» seedlings are used. With directed pollination of varieties, the fruit set ranged from 15 to 69 %, the percentage of fruit set increases when pollinated with a mixture of three varieties. A partial transfer of decorative traits from parent varieties was established, however, the high variability of the transferred characteristics does not allow us to identify clear patterns at this stage of the study. Phlox hybrids bred in the Siberian Botanical Garden are first of all selected for resistance to diseases and abiotic conditions of the Siberian region, then for decorative qualities. The article contains a description of six hybrids obtained in the Siberian Botanical Garden, promising for registration as new varieties.","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":"139363628","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}

In park areas, compared with the control, the content of chlorophylls a and b and the a / b ratio are lower. The best conditions for the growth of birch trees (closeness of crowns, distance from highways, and lower frequency of attendance) contribute to an increase in the content of chlorophyll a and b in the leaves. The sparse location of trees in squares and their intensive visits, emissions from industrial enterprises, cars and thermal power plants lead to a decrease in the content of chlorophyll a and b in the leaves. Regardless of the growing conditions, a regular increase in the content of chlorophyll a is observed during the growing season. A change in the content of chlorophyll a in birch leaves has been revealed; in the city of Biysk, it is changing downward in the following row of growing places: control -> parks -> squares -> highways -> petrol stations -> factories -> CHP. In dynamics by month, a slight increase in the concentration of chlorophylls in July was detected in all places of birch growth, and then its decrease in August.","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":"139363751","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}

(Theaceae). The species is found in a single in Dalat, southern Vietnam. It is known that the Da Lat Plateau has suffered from habitat loss, degradation and fragmentation in places, and deforestation is directly impacting the range of C. dalatensis. The species is listed as Critically Endangered (CR). To provide an appropriate method for the conservation and sustainable development of this species, the study experimented with air layering and planting in their habitat (in situ). An ex situ experiment for C. dalatensis with several other species was also performed to assess their adaptability. The results showed that the average rooting time was from 3.5-4 months, the rooting rate of air layering was 78.89 % and the survival rate after planting was 96.06 %. Plants were replanted grow well in the habitat of the original population. In a new environment, the survival rate of C. dalatensis is lower than that of other species of the same genus, only 17.14 %. The surviving plants have not yet shown the ability to grow. Thus, at this time, in situ conservation method for C. dalatensis is appropriate.","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":"139364136","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}

Grebenyuk","doi":"10.14258/pbssm.2023008","DOIUrl":"https://doi.org/10.14258/pbssm.2023008","url":null,"abstract":"Between 2013 and 2020, 47 communities with seven species of the genus Delphinium were studied on the territory of 12 regions of the southeast of European Russia. The analysis of habitats by vegetation cover using the ecological scales of L. G. Ramensky showed that soils under communities with species of the genus Delpinium are often quite rich and very slightly alluvial. D. subcuneatum communities grow in habitats with the highest moisture-meadow-steppe (moist-steppe) and wet-meadow habitats; communities of D. duhmbergii grow in less humid habitats with dry-meadow (and fresh-meadow) moisture; with dry-meadow (and fresh-meadow) and meadow-steppe (moist-steppe) humidification - communities of D. dictyocarpum, D. litwinowii, and D. pubiflorum; in meadow-steppe (moist-steppe) humidification, communities of D. sergii. D. puniceum communities grow in the least moisture-provided habitats, with moisture ranging from dry-steppe and middle-steppe to semi-desert (desert-steppe). The biomorphological composition of communities with species of the genus Delphinium is dominated by hemicryptophytes, among which, the most numerous are tap-rooted, short-rhizomatous, and long-rhizomatous. The composition of cenomorphs reflects the confinement of communities with the majority of Delphinium species presented in the study to the forest-steppe zone, and communities with D. sergii and D. puniceum - to the steppe and semi-desert zone. In communities, the first place among trophomorphs is occupied by mesotrophs, and the second by megatrophs. The spectrum of hygromorphs is quite wide and includes species from xerophytes to ultrahygrophytes, however, xerophytes, mesoxerophytes, xeromesophytes, and mesophytes are the predominant groups most often. Judging by the predominance of heliophytes among heliomorphs, communities with all studied species of the genus Delphinium prefer open spaces. The spectrum of thermomorphs of all studied communities is dominated by mesotherms, for which the ecological optimum coincides with a moderate heat supply regime.","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":"139364162","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}
