Metasequoia glyptostroboides Hu et W.C. Cheng has been grown in the Peter the Great Botanical Garden of the BIN RAS since 1952, where it was first introduced into cultivation in Russia. It is the most winter-hardy representative of the Taxodiaceae family suitable for open field culture in St. Petersburg. The best specimens reached 14.4 m in height with a trunk diameter of 29 cm at the age of 69 years. In 2018, seed production was recorded for the first time. Seed offspring were obtained in 2020. In the conditions of the warming of the climate of St. Petersburg in the first two decades of the 21st century, there is a surge in the generative ability of woody exotics, an increasing number of trees and shrubs are beginning to bear fruits and seeds.

The author investigated, recorded, observed and analyzed the major wildflowers in Mount Huangshan---the natural and cultural heritages listed by the ESC0 of UN for the first time. On the basis of their desirable characteristics, more than 300 wild ornamental species are divided into 8 categories -–-historical old trees, rare and endangered species, evergreen ornamentals, blooming trees and shrubs, plants with colored foliage and fruit in fall, vines, herbaceous ornamentals and ground covers, and ornamental ferns. Mount Huangshan is one of the richest regions of native ornamentals in Eastern China and the most famous natural beauty in Pan-China. There are about 1500 wild landscape plants in and around it. Finally the paper puts forth some proposals and methods for introduction and utilization of wild ornamental plants. That is, investigation, classification,acclimatization and cultivation of them, and building a sort-out botanical garden for the germplasmic preservation and the flourishing landscape tourism.

Background. The study and mobilization of natural flora species in botanical gardens allow the curators to save biological resources of useful plant species, and recommend them for urban landscaping. In the flora of Russia, one species of a woody vine from the genus Aristolochia L. is A. manshuriensis Kom.; it is included in the Red Data Book of Russia.Methods The material for the study was A. macrophylla Lam. and A. manshuriensis from the collection of the Peter the Great Botanical Garden maintained by the Komarov Botanical Institute of the RAS. Winter hardiness was assessed; plant height, stem diameter, and crown diameter were measured. The sizes and age are given according to the state of the plants in the fall of 2017. Seed quality was assessed with due regard to the approved guidelines. X-ray analysis of fruits and seeds was carried out using the methods developed for the use of microfocus radiography for seeds and fruits.Results. A. manshuriensis has been grown in the Peter the Great Botanical Garden since 1909. The first flowering was observed in 1918 and 1919, the first fruiting in 1924. Currently, plants of the third or fourth generation are present in the collection. A. macrophylla has been known in St. Petersburg since 1816. Over a 200-year period of introduction, only flowering was observed. For the first time, fruiting in this species was registered in 2007; since 2014, second-generation plants have been grown. Analysis of the seeds collected in 2016 and 2017 showed that they are viable and of high quality in both species of Aristolochia. These species are winter-hardy, demonstrate rapid growth, and may somewhat vary in the timeframe of the passage of main phenological phases in their seasonal rhythm of development.Conclusion. For laying out plantations, it is better to use seeds. A. macrophylla and A. manshuriensis are promising for wider cultivation and use in vertical landscaping.

В данной лекции содержится теоретико-практическая характеристика организации и деятельности Следственного комитета Российской Федерации в различных сферах правового регулирования общественных отношений. Автор считает весьма позитивным разделение функций прокурорского надзора и производства следствия, что позволило достигнуть необходимого баланса полномочий. Это состояние весьма эффективно отразилось на системе защиты прав и интересов личности на стадии досудебного производства. В целом такая глобальная реорганизация следственных органов проведена впервые. Исторически идея создания «независимого следствия» возникла еще во времена императора Петра Великого, когда была сформулирована концепция вневедомственного предварительного следствия, а реализована она была только в XXI веке. This lecture contains a theoretical and practical description of the organization and activities of the Investigative Committee of the Russian Federation in various spheres of legal regulation of public relations. The author considers the separation of the functions of prosecutor's supervision and investigation proceedings to be very positive, which made it possible to achieve the neces- sary balance of powers. This condition was very effectively reflected in the system of protecting the rights and interests of the individual at the stage of pre-trial proceedings. In general, this is the first time such a global reorganization of the investigative bodies has been carried out. Historically, the idea of creating an "independent investigation" arose back in the days of Emperor Peter the Great, when the concept of a nondepartmental preliminary investigation was formulated, and it was realized only in the 21st century.

Dynamics of the sea ice cover in Peter the Great Bay is considered, for the first time for its whole area, on the base of satellite images received in 2004-2011 from the spectroradiometers MODIS mounted on the satellites Terra and Aqua. High spatial resolution maps of the ice drift are constructed for various wind conditions. Mean values of the drift velocity and wind coefficient are calculated for four parts of the Bay. In usual conditions of winter monsoon, the ice in the central part of Peter the Great Bay drifts southward with the velocity 0.5-0.6 m/s with deviation from the wind direction about 40° to the right; the ice at the western coast drifts along the island chain with the velocity 0.1-0.4 m/s under wind of any direction in the quadrant from northwest to northeast.

The article deals with one of the most relevant topics of the modern city and ecology - the problem of landscaping in Volgograd. The city is characterized by an industrial urbanism, with a high concentration of population, saturation of production facilities and vehicles, which contributes to a high level of negative impact on the environment. The pace of greening of the city lags behind the pace of construction of the residential sector, and the existing green spaces do not meet the sanitary and hygienic, aesthetic requirements. The prospects of this problem are determined, the existing green spaces are considered, data on the climatic conditions of the city and the ecological situation are given. Improvement in the field of landscaping is associated with the scientifically sound placement of green spaces, taking into account all the factors that affect the growth and development of plants in the urban environment. Unfortunately, due to the uneven distribution of the assortment of trees and shrubs, the species composition of the central streets and squares of the city is extremely poor. The study focuses on the role of the botanical garden in urban landscaping and aims to create recommendations for the sorting of tree and shrub plants for urban landscaping. As a result of the analysis of the assortment of ornamental plants of the open ground of the botanical garden, the article proposed species and varieties of woody and shrubby plants that have passed the introduction tests for more than 5-10 years. Recommendations for sorting are aimed at improving the ecological situation of the city and greening the recreation areas of citizens. The proposed list of tree and shrub species cannot fully solve the problem of greening the city, but it will help to significantly enrich the composition of tree and shrub plants.

Qualitative And Quantitative Characteristics

This paper analyzes the current state of landscaping in Ishim. The data on the qualitative and quantitative characteristics of woody plants have been obtained for the first time; the assessment of trees and shrubs state is based on the analysis of the vitality index. A database of green plants within 21 objects in Ishim was created and analyzed. The paper also contains data on the species diversity of trees and shrubs in Ishim. It turned out that the objects under study have trees and shrubs placed in special dividing strips, linearly, in rows or in small compact groups, less often they are planted singly. The species composition is represented by 47 species from 28 genera, 16 families and 2 divisions. The biomorphological structure is represented by trees (25, or 53% of species) and shrubs (22, or 47% of species). The total composition of tree and shrub plantations, determined by the number of trunks (bushes) and the percentage of woody plants, is 2854; the composition of the preserved ones is 2 815 (99%) pieces; the ones assigned for removal are 39 (1%) pcs. The vitality index shows that among 85% of the studied objects of the town at the time of the survey were healthy, among 10% of the objects they were qualified as damaged, among 5% of them were severely damaged. Based on the results of examining crowns and trunks of woody plants, signs of diseases and pests, a plan of measures for the treatment, restoration and preservation of woody plants was drawn up and recommendations were given for caring, sanitary felling and removal of single specimens.
