The article presents the results of the study of adaptation features in the introduction of the Central Asian species Tulipa tschimganica Botschantz. in the collection of the Central Siberian Botanical Garden SB RAS. Morphometric changes were found towards a decrease in androceus and an increase in the gynecus of the flower; in leaves and capsule fruit, with a decrease in length, their width increases. When studying the morphology of seeds, both positive and negative correlations between the length of the seed and the size of the embryo were revealed. Correlation analysis showed a moderate or strong effect of some eco-factors on seed productivity and its implementation. The high average percentage of seminification (34%) and seed germination in open ground (up to 61%) allows to characterize this species as viable for the conditions of the city of Novosibirsk.

In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum) in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

A spontaneous intergeneric hybrid of Sorbus and Cotoneaster – Pozdnyakov’s sorbocotoneaster (× Sorbocotoneaster pozdnjakovii Pojark.) is an endemic of the South Yakutia. It is known from the river basin Aldan in the areafrom the city of Tommot to the mouth of the river Uchura and on the Aldan-Amga interfluve. It grows in the undergrowthof sparse pine and larch forests on stony-gravelly limestone slopes. It was first found by L. K. Pozdnyakov, a forester,an employee of the Institute of Forest of the Siberian Branch of the USSR Academy of Sciences, on September 9, 1950,when examining forests on permafrost in Yakutia: “in the area of the confluence of the Aya-Sullalah river into Aldan,105–110 km down the Aldan from Tommot” (from the letter of L. K. Pozdnyakov to A. T. Grevtsova, 1982). The article provides data on the origin of the specimens × Sorbocotoneasters, the morphological description of leaves, flowers, fruits,the peculiarities of growth and development in conditions of Kiev, micrographs of pollen grains, micrographs of theendocarp of fruits of three forms, the beginning of the destruction of the scutellum and hypostyle from the ventral side ina hybrid of the third form.

The paper analyzes the features of seasonal development of Tulipa tschimganica Botschantz. in the conditions of the recipient region. Comparative morphometric characteristics of ex situ and in situ are given. Representatives of the species T. tschimganica growing in high mountains are successfully acclimatized in the Novosibirsk Region. Late flowering and resistance to viral disease variegation adds value to this species in floriculture and gardening in the spring. The temperature characteristics of the initial stages of phenophases are established. The beginning of flowering in six of ten years of observations occurred in the second decade of May. By duration, flowering can be characterized as short - 7-8 days, with an average duration of 10-12 days and a long one - 13-15 days, respectively. It was found that, despite the high rates of maximum and average daily temperatures, lower temperatures increase the flowering period of T. tschimganica . The flowering period in the recipient region, compared with the city of Tashkent, shifts by two months and starts from the second decade of May. The range of experimental plants morphometric parameters, such as plant height, leaf width, length and width of the ovary, and fruit width, increases. The rest of the studied parameters remained in situ . The study of the ontogeny of individuals grown from seeds collected from introduced plants is being carried out. To date, the plants are going through a long pregenerative period of ontogenesis. Successful completion of the full cycle of annual shoots development and the formation of high-grade mature seeds characterize this species as successful for introduction and use in gardening in Novosibirsk.

One of the promising areas of landscaping is container. The use of plants in containers in the central part of the city will create landscaping in areas where trees and shrubs cannot be planted directly into the soil. Perspective, in this regard, is the use in landscaping in the frost-free period of tropical and subtropical plants. This method does not solve the problem as a whole, but it can be a great original addition. The aim of this work was to analyze the participation of tropicogenic flora plants in the landscaping of the city of Kryvyi Rih and to identify perspectives for greening of metropolitan species from the collection of tropical and subtropical plants of the Kryvyi Rog Botanical Garden of the NAS of Ukraine. Surveying of the city's greening showed that the use of subtropical and tropical plants as a container container during the warm period is quite limited, and the single facts of their use in containers are revealed. For these purposes, plants of Chamaerops humilis L., Agave americana L., Brugmansia suaveolens (Humb. Et Bonpl. Ex Wild.), Chlorophytum comosum (Thunb.) Baker., Chlorophytum comosum 'Variegatum', Nerium oleander L. varieties were used. In the presence of extremely rich collections of tropical and subtropical plants in the botanical gardens of Ukraine, there is an opportunity to significantly expand this list. The Kryvyi Rih Botanical Gardens protected soil collection has 988 taxa. Based on study of plant biology, the collection identifies and identifies species that are appropriate for landscaping metropolitan areas by planting them in portable containers, and some of them directly into the soil as accent plants. When selecting plants for landscaping in the open ground it is important to take into account the features of their stay in the winter in the halls or greenhouses (temperature and light modes).

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.
