The results of the study of alien species of woody plants found in the urban area are presented. Alien plants were understood to be foreign or adventitious plants. City parks, squares, street plantings, territories of scientific and educational institutions, wastelands, ravines and other ruderal habitats within the city were surveyed. During the study, we identified 38 species belonging to 14 families and 26 genera. It is shown that the taxonomic spectrum of the studied flora is dominated by the number of species from the family Rosaceae (genus Prunus) and Salicaceae (genus Populus). According to the life form, summer-green trees and shrubs are most often found. By origin, most of the species were imported from North America, as well as from the adjacent territories of the Asian continent (Central Asian and East Asian species). European and Siberian species in urban plantings are insignificant. It was found that alien species of woody plants in Khabarovsk were deliberately imported for landscaping purposes. They are kept in the landing sites without being introduced into the natural cenoses.

The relevance of the study is due to the fact that city tram tracks, embankments and right of way are specific ecotopes that are subject to significant anthropogenic disturbances and are places of synanthropic plants concentration. We have collected 59 species from 23 families and 49 genera of flowering plants. The family spectrum is dominated by representatives of Asteraceae, the leading family of regional flora. In the generic spectrum, most genera contain one or two species each, which indicates a sufficient floristic capacity of the technogenic ecotope of tram tracks. In terms of life form, perennial herbaceous plants with underground organs survive on the tram tracks, ensuring the constant renewal of plants. Approximately the same number of alien (or adventive) and local (or native) plants have been identified by origin. As expected, alien species are confined to ruderal habitats and are characterized by wide ranges (cosmopolitan, Eurasian-North American, Eurasian types). From local species on tram tracks, plants of open habitats (forest-meadow, meadow, forest edge and slope) find suitable ecological niches.

The article provides results of palynological and algological analysis of peat deposits from MIS-5c in the Kiryas site. Sampling and analysis were carried out from the same horizon that was analyzed by other methods in already published works with the dating of the underlying layer at 105.5 ± 3.6 thousand years ago. Algological analysis and spore-pollen analysis were carried out. Three successive changes in vegetation were identified in the territories adjacent to the studied section. Changes in the composition of algal communities were used to trace changes in watering and the trophic status of the peat bog. Peat formation began with warming in time after 105 thousand years ago, with forest-tundra vegetation; in the second stage, a biome close to the modern northern taiga was formed; in the third stage, cooling occurred with the formation of a forest-tundra community and the end of peat formation. Complex conjugate analysis of stratigraphic records by various methods increases the reliability of reconstructions of natural changes. The abundance of algae remains allows us to conclude that the water level and the trophic status of the peat bog have changed.

The article clarifies the species composition of the genus Kailashia using molecular phylogenetic methods and compares the results with the morphological data presented in the paper of Kljuykov et al. (2022). For molecular phylogenetic analysis, herbarium samples were taken from the MW, HARV, KUN and NAS herbariums. Internal transcribed spacers (ITS1 and ITS2) of the 18S-26S region of nuclear ribosomal DNA were chosen as a molecular marker. The description of the new species Kailasia bouffordii based on the results of previous morphological studies (Kljuykov et al., 2022) is consistent with the results of the reconstruction of molecular phylogeny. Kailashia is a small natural genus with three endemic species (K. robusta, K. xizangensis, K. bouffordii) that form a high posterior monophyletic group in the Selineae clade.

Germination of seeds and survival of seedlings are important characteristics of the functioning of communities. There are few observations in the literature on the dynamics of seed germination in untouched alpine communities. Severe abiotic environmental factors characteristic of high mountains make it difficult for juvenile plants to take root, and they show high mortality in the first year of life. For 9 years (2011-2019), all juvenile plants were recorded on 5 m2 of the mountain-tundra community of the Khibiny Mountains and their further life was traced. For most plants of the alpine tundra community, low germination and high mortality of juvenile plants in the first year of life were confirmed. Seeds of some species of undisturbed plots, did not germinate during the observation period, most of the rest they did not survive. In species of slightly disturbed places, the number of seedlings was proportional to the number of species in the community, with the exception of species that do not have vegetative propagation. In the latter, seed germination was higher. A surge in the number of seedlings was observed in 2016 and 2019. The surviving individuals did not pass into the generative age state for 7-9 years of observations, which confirms the duration of the life cycle of alpine species.

The information about the timing and duration of flowering of woody plants makes it possible to plan the landscaping so that the plantings are the most decorative. Trees and shrubs are the most decorative during their blooming. The article presents key data on the flowering of woody plants in the Polar Alpine Botanical Garden-Institute (PABGI). The objects of the study were trees and shrubs in the PABGI collection fund. The material of the work was the data of phenological observations for the period from 2001 to 2020. We studied the beginning and duration of the growing season, the duration of the prefloral period, the timing, duration and abundance of the flowering. Trees and shrubs in the PABGI collection are characterized by an early beginning and a short duration of the growing season, a short and medium duration of the prefloral period. Early flowering in the second half of May is typical for wind-pollinated and flowering before leaf-out plants. The mass flowering of trees and shrubs is observed in the second decade of June and the first decade of July. Woody plants with a long prefloral period and long-blooming plants flower in August and September. Most trees and shrubs bloom within 6-10 or 11-15 days. The abundance of flowering is rated from moderate to excellent.

Currently, the genus Allium L., which is one of the largest genera of the Monocotyledon class, has more than 1000 species in its composition. In the flora of Kazakhstan, the genus is represented by at least 130 species. The species of this genus are characterized by a variety of morphological characteristics, which makes it difficult to determine them. The ecological range of the species of the genus is also wide and extends from the alpine and subalpine belts to deserts. According to modern data, 25 (19 % of 130) alliums growing in Kazakhstan are found in the Aral-Balkhash region. The aim of the research was to study critically the diversity of species of the genus Allium from 3 sections (Haplostemon Boiss. -7; Porrum Don - 3, Molium Don - 5) of the flora of the Aral-Balkhash region. The conspectus presented in the article is based on the critical review of available herbarium materials: the Institute of Botany and Phytointroduction (AA), (Almaty, Kazakhstan), the digital herbarium of the Lomonosov Moscow State University (Moscow, Russia), the Herbarium (TASH) of the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan, taking into account the modern system of the genus Allium. For each species, information on the biological characteristics of the species, their ecological confinement and geographical distribution is provided. Screening of herbarium samples revealed 158 plant vouchers belonging to 15 species from 3 sections. The results of the analysis of the edaphic confinement of species, in general, confirm the validity of the distribution of species in the presented sections.

The search for plants that can be indicators of geoactive zones has continued. A 180-year-old cowberry pine forest was investigated on the territory of 30 hectares, where there was a grass-roots fire 15 years ago, in the forests of Perm around a locus N58°0'48.05", E55°53'4.46". The methodology of the work included mapping of synusias of the cat’s foot dioica (Antennaria dioica (L.) Gaertn.). Centers of favorable geoactive zones of six types with sizes from 1 to 55 m, as well as pathogenic zones of Hartman and Kurri were found and mapped near them. 12 sinusias were detected, while the three largest were double and were located in two zones of 3 m in size at once. All the sinusias were located in the comfort zone of the 3 m zone, so the cat’s paw can serve as a good phyto-indicator for zones of this type. In addition, all of them were also located in the zone of action of the «senior» zones with dimensions of 8, 16, 32 and 55 m. These zones can be arranged linearly (URL: https://youtu.be/bCep8MCe4M8) and arrange a triangle and even a cross (URL: https://youtu.be/ rr_jDVzOgbk). The results of the work confirm the hypothesis of the action of «subtle» energies of the Earth through these zones with a frequency of thousands and millions of hertz, which probably coincide with the radiations of plant biofields that form similar phenomena on them. There are no devices with such characteristics yet, so you can start studying the physical properties of the soil (electric potentials, magnetic fields, soil heating on sunny days) at the points of the Earth’s energy output. They will be pointed out to us by trees and some perennial plants, including cat’s foot, and in the future other plants of the ground cover.

There are no devices with such characteristics yet, so you can start studying the physical properties of the soil (electric potentials, magnetic fields, soil heating on sunny days) at the points of the Earth’s energy output. They will be pointed out to us by trees and some perennial plants, including cat’s foot, and in the future other plants of the ground cover.","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":"139363456","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}
Nowadays, when studying the fruiting of tree species, it is of great interest to understand the influence of weather factors on the inter-annual variability of fruit and seed yield. Siberian stone pine covers a large part of the Asian part of Russia and is valued primarily for its seeds. Therefore, the sustainable functioning of ecosystems depends on the yield of Siberian stone pine. Yield estimation was performed by examining bark marks from annually laid seed cones during the study period. The following categories of cone scars were recognized: (1) small triangular scar remaining from an aborted cone bud that dies before pollination; (2) triangular scar remaining from an aborted flowering seed cone soon after pollination; (3) an oval scar from a 1-yr-old conelet that developed after pollination but was aborted in the winter; (4) a large oval resinous scar from a fully mature seed cone. When studying the effect of temperature on Siberian stone pine yield, it was found that there is an increased sensitivity of initiating cone primordia to air temperature in the first decade of August. The cool weather at the beginning of August (+16 °C) contributes to the abundance of cones. On the opposite, if the temperature in the first ten-day period of August exceeds +19 °C, fewer buds are deposited. And further decrease of temperature to +16 °C in the second ten-day period of August has no effect on bud establishment.
