Trees And Shrubs

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.

The article presents the results of the research work on the peculiarities of recultivation of the ash dumps of power station No1 (PS1) in the city of Khabarovsk. The research showed that the climatic conditions of the region promote the dust dispersal of toxic agents from the surface of the ash dump. The pollution of the air basin here can be attributed to the extremely high level of pollution (EHP), the priority pollutant is the dust containing heightened concentrations of heavy metals (Pb, Mn, Cu, Cr, Co, Ni, Cd). As a result it leads to the deterioration of the population’s health, especially to the high level of respiratory organs diseases. The research of the sprouting of the herbaceous plants (mixture of timothy-grass, clover and mustard) on prepared model soils showed their healthy growth. The ash chemical composition was studied. It showed high concentration of toxic chemical elements (Hg, Be, Sr, Cd, V, Th, 40K, Cr, Mb, AS, Sb,Se, Te, Pb, Ni, Co). The migration intensity of heavy metals ions into the plants was analyzed. On the basis of the experimental research the optimum composition of the substrate was revealed and recommended for recultivating the ash dump of PS1, namely: soil+sand+ash. Climatic conditions of the Khabarovsk Krai do not permit to recommend the sand+ash substrate for recultivation because of strong winds.

The article presents the results of engineering and geoecological studies of the salinity of the soils of the city of Nukus to the ground water level. The results of observations of changes in the city’s ground water level are presented. It was found that the increase of the water level leads to additional salinization of the soils, which worsens the ecological situation of the city, has a negative impact on green spaces and reduces the longevity of plants. According to the results of research, maps-schemes of salinization of the city’s soil were compiled. Studies have shown that the soils of the territory of Nukus are saline and mainly belong to the chlorine-sulphate type of salinity.

Trees and shrubs of green spaces can tolerate some physiological parameters. They can adapt to climatic conditions, hence, reduce air pollution and can be used as biological indicators in various researches. The present study aimed to explore the impact of urban air pollution on some parameters such as fresh, dry and turgor weight, amounts of chlorophyll and carotenoid pigments, and electrolyte leakage of 18 ornamental tree and shrub species in marginal and downtown parks of Rasht, Iran. The results revealed significant differences in turgor weight, photosynthetic pigments, and chlorophyll a/b ratio, but insignificant differences in electrolyte leakage between the marginal and downtown sites. The results indicated that all quantitative variables of the leaves differed significantly (p ≤ 0.01) among the species, except for fresh weight.

Based on a comprehensive assessment of the state of the park landscape, the level of its anthropogenic transformation is determined, which is necessary to identify the potential for restoring the natural biodiversity of the object. It is reported that the plantations and soil cover of the park of the 50th anniversary of VLKSM are very heterogeneous; they reflect the history of park establishment. The soil cover consists of three main types: sod, bog and urbanozem. It should be stressed that the best preserved part of the park is the plot with boggy soils around the pond. Herbaceous plants growing on the plot are very similar to the species composition of the ground cover of overgrown peat bogs. Over the 40 years since the foundation of the park, a high level of pollutants has been accumulated in the soil, which allows us to state that the negative impact occurs constantly. Consequently, the existing plantings are insufficient to protect visitors from vehicle emissions from the roads along Yasnaya and Shaumyana streets. There are enough natural elements in the park of the 50th anniversary of VLKSM; this should be taken into account in its redevelopment. There is an opportunity to restore the reservoir and return the plantings to their natural appearance. It is proposed to add elements of landscape decoration in the park.

The paper presents characteristics of lilac flowering duration in the South-Ural Botanical Garden-Institute of Ufa Federal Research Center of the Russian Academy of Sciences. When selecting prospective species and sorts for landscaping purposes for each region, it is necessary to obtain a comprehensive assessment of decorative features. Lilac is now widely used in green building and is one of the most popular ornamental shrubs. The duration of flowering is one of the most important characteristics of ornamental plants and determines the decorative effect of the entire landscape composition. The paper presents the study results of the flowering duration of 11 species and 33 sorts of lilacs of the botanical garden collection for the last 7 years (2011-2017). The results obtained are shown in comparison with the data of earlier studies (2005-2009). The data analysis showed that in 2011-2017 the average lilac species flowering duration was 7-15, and that of varieties 13-15 days, which is 5-6 days shorter than the flowering period of the same taxa in 2005-2009. It is established that such a result is a consequence of changes in the climatic situation in the region. The obtained data on the lilac species flowering duration in Ufa, as well as the influence of climatic conditions on it, make it possible to successfully apply the studied species and varieties of lilacs for landscape design purposes in the Republic of Bashkortostan and adjacent territories.

The results of physiological, morphological, anatomical peculiarities of introduced plants of Araliaceae Juss. have been given. Study of seasonal growth and development peculiarities of Araliaceae Juss.  showed that most of these plants were introduced successfully but the process was complicated by climatic conditions of the area in city Kiev. According to a comprehensive assessment a large number of studied species were highly evaluated for decorative effect. Introduced species of family Araliaceae Juss. are characterized by high-level adaptation to local soil and climatic conditions in Botanical gardens of Kiev. The vast majority of them bloom but not all can form seeds. Thus, among the introduced plants only five representatives of genus Acanthopanax – Acanthopanax lasiogyne, Acanthopanax divaricatus, Acanthopanax sieboldianus, Acanthopanax trifoliatus and Acanthopanax wardii have high level of adaptation. To determine the prospect of cultivating research species we assessed the degree of winter resistance by the 5-point M. K. Vechova scale on the basis of visual observations in conditions of the open ground. The level of adaptation of plants was evaluated in the city Kyiv using the estimation scale measured in points and in percentages. Results of researches showed that the species have a high resistance to the effects of adverse factors. All types of this family are promising for introduction into culture and can be widely used in various branches of the national economy.  A comprehensive assessment of the decorative effect of ornamental plant species was carried out by the O. G. Horoshyh and O. V. Horoshyh scales, according to which the decorative effect of the vast majority of studied species was highly appreciated. The results of our study shows that the introduced species of Araliaceae Juss. have a good prospect for further their use in ornamental gardening, urban greening and landscape design in private territories of citizens.

The perception of the ecological situation in the Moscow metropolis was studied using an online survey of the city dwellers. Quota sampling, proportional to the age and sex composition for each municipal administrative district, was used to ensure representativeness. The influence of the high-level values (basic, HLV) according to Schwartz and socio-demographic factors on the respondents’ perception of the ecological situation in the metropolis was studied during the research. The results obtained showed no statistically significant differences in the perception of factors that negatively affect the ecological situation in Moscow, depending on the value orientations. At the same time, the perception of changes in the ecological situation in the city differs in different clusters based on socio-demographic indicators. The change in the ecological situation is most acutely recorded in clusters, where young people occupy a significant share. Notably, in the cluster where women prevail, the change in the situation is seen as a deterioration.

Araceae is one type of plant that has a fairly high level of diversity and also rich in benefits such as a source of food, ornamental plants, and medicine. Research on the characteristics of Araceae in Indonesia is still limited. The purpose of this study was to identify Araceaeplants based on morphological structure and analyze the morphological characteristics ofAraceae in Liwa Botanical Garden, West Lampung. This research was conducted from November 2019 to January 2020. Data were collected at Liwa Botanical Garden, WestLampung based on exploration and observation collection methods. Morphological structure data were analyzed as descriptive and qualitative. The parts of plants that are compared between Araceae plants are the shape, size of leaves, petiole, and inflorescences. Observations show that 21 genera of Araceae are consisting of 26 plants. Araceae plants have three different ways of life, namely terrestrial, epiphytic, and aquatic. The shape of the leaves is ovatus, cordatus, lanceolatus, cuneatus, needle, peltatus, sagittatus, hastatus, palmatisect, bipinnatisect and tripinnatisect. The characteristics of this plant have compound interest with cob types (spadix) which are covered by a spatha with two types of inflorescences, namely unisexual and bisexual.

Abstract. The purpose of the research is to isolate species of annual and perennial herbaceous plants that are promising for the tasks of accelerating the sequestration of atmospheric carbon, resistant to local soil and climatic conditions and having high productivity from the collection fund of the botanical garden of the Ural Federal University. Methods. The article presents data on the productivity of four types of herbaceous plants: Amaranthus caudatus L., Amaranthus cruentus L., Polygonum weyrichii F. Schmidt and Echinops sphaerocephalus L., grown in the botanical garden. All the research objects were grown under the same conditions. Productivity was measured at the beginning of September. The data were processed using standard statistical methods. Results. It was revealed that the plants P. weyrichii is the most productive in terms of both fresh and dry yield. The yield of the P. weyrichii increases in years with sufficiently high moisture content. Aridity and high summer temperatures have a negative impact on the growth of the P. weyrichii. Amaranths gain a large aboveground mass due to their belonging to the group with the C4 type of photosynthesis. High summer temperatures have a positive effect on the growth and development of amaranths, while correlations with the amount of precipitation are statistically insignificant. The plants E. sphaerocephalus showed average values for productivity and requires further study. It is recommended to grow the plants P. weyrichii in a sufficiently humid area. Amaranth, being a drought-resistant plant, is highly productive in any years, especially in years with the value of the hydrothermal coefficient (HTC) less than 1.0. The scientific novelty lies in the fact that the features of the cultivation of the studied crops are considered not only for forage purposes but also from the point of view of atmospheric carbon deposition and cultivation on potential carbon farms in the changing climate of the region.
