Features of formation of parks-monuments of lanscape art of the second half of the XX century of Ukrainian Polissia

The formation of park-monuments of landscape art was analyzed from a historical perspective. In the second half of the twentieth century, two national and nine local park-monuments of landscape art were created in Ukrainian Polissya. The purpose of PMLA is the protection and the preservation of the most prominent and valuable examples of park construction in order to use them for aesthetic, educational, scientific, environmental and health purposes. By the placement in the planning structure of inhabited localities are defined city, village and district parks. The motivation for the creation of parks was the preservation, reproduction and enrichment of tree diversity in the conditions of the Ukrainian Polissya. In the parks were planted technical, fast-growing, rare species, and species of woody plants valuable for forestry and landscape gardening with their subsequent use for scientific and economic purposes. Some of the plantations in the parks were memorable, anniversary, or dedicated to significant events (the anniversary of the October Revolution and the birthday of V.I. Lenin). In Ukrainian Polissya, there are three parks created on the basis of existing oak plantations “Klevanskyi Park”, “Park Antonivka”, “Bondaretskyi”); one - on the basis of man-made plantations with Acer platanoides L., Carpinus betulus L., Fraxinus excelsior L., Tilia cordata Mill. (“Ovrutskyi”); three parks of culture and recreation (“Horodnianskyi”, “Vysokivskyi”, “Slovianskyi”) including a meadow park (“Slovianskyi”), a children's park (“Bondaretskyi”), three arboretums (“Dubechnenskyi”, “Bairak”, “Novostavskyi dendropark”, “Zhornivskyi”), which were transformed over time, or which were granted the status of PMLA. By the size, PMLA were small, medium, and large with star, axial, fan, loop, cross-shaped and combined planning structures. In four PMLA, there were man-made and natural reservoirs, and a fountain. Five parks were combined (memorial and park of culture and rest); there were concentrated memorial complexes, monuments, and an obelisk. Plantings of parks are represented by groups, solitairs, alleys, ordinary plantings, hedges, and sometimes by groves and massifs. On the territory of 11 PMLA grew 178 species of woody plants, with 121 of them being included to the IUCN Red List. In 4 parks, since their creation the number of species increased by 75–129%; in 6 parks tree diversity decreased, with 29 to 87% of tree plant species remaining, among them 66–94% of trees were rare. 11 PMLA are valuable centers of tree diversity and unique plantings of Ukrainian Polissya; and an example of the formation of didactic, ethnographic, memorial, children's, culture and recreation, and combined parks that need further protection and expansion of the area and collection. Some parks are in need of planting reconstruction.

Fruit and seed morphology in some representatives of the genus Malus Mill.

Aim. The study of morphological characteristics of fruits and seeds of the genus Malus is the key to the effective use of the apple genetic diversity in landscape-gardening, fruit growing, introductory and breeding. Methods. Morphological features of fruits and seeds of nine species and three varieties of apple (M. baccata, M. coronaria ‘Red Tip’, M. floribunda, M. fusca, M. halliana, M. niedzwetzkyana, M. × purpurea, M. × purpurea ‘Ola’, M. × purpurea ‘Royalty’, M. × purpurea ‘Selkirk’, M. trilobata, M. tschonoskii, M. toringoides) were studied. Generally accepted tech- niques of research was used. Results. The fruit weight of apple species and varieties varied from 0.30 g (M. fusca) to 61.20 g (M. coronaria ‘Red Tip’), the weight of 1000 seeds — from 5.00 g (M. fusca) to 62.77 g (M. coronaria ‘Red Tip’). The largest number of seeds in the fruit was characteristic of M. toringoides (6.64), the smallest — M. tschonoskii (0.25); developed seeds were not detected in the fruits of M. trilobata for 2019–2020 years. The lowest level of variability among biometric indicators of the studied representatives of the genus Malus was in terms of fruit height, fruit diameter and seed height, the highest — in terms fruit weight and number of seeds in the fruit. Conclusions. Detailed characteristics of fruits and seeds of the genus Malus, growing in the National Dendrological Park “Sofiyivka”, were compiled as a result of research. The obtained data can be used as a supplement to the botanical characteristic, and as a comparative material for taxonomy and phylogeny.

Biomorphological features of floribunda roses leaves and their importance for ornamental gardening

The results of morphometric analysis of the leaves in floribunda roses varieties, such as Pomponella, Lovely Green, Carmagnola, Arthur Bell, Lilli Marleen, Westpoint, Minerva, Novalis, Goldelse, Rotkappchen, Friesia, Lavaglut, Iceberg, Santa Monika, Mathias, Bella Rosa, Cream Abundance, Hans Gonewein, Let's Celebrate and Gebruder Grimm, which have different origins and differ significantly in morphological and decorative characteristics are presented. The studies were conducted during 2018–2021 on the experimental plots of the Department of Landscape Gardening of Uman National University of Horticulture according to the generally accepted method. The description of the morphological traits of the varieties was carried out by the method of visual assessment using measurements and calculations. As a result of the research, it was found that the studied genotypes significantly differ in the biometric parameters of the compound leaf, features of the surface of leaf blades, their shape and size. The highest leaf blades areas were noted in the varieties Novalis 15.1 сm2, Rotkappchen 12.0 cm2 and Pomponella 11.8 cm2. The lowest biometric traits of the leaf were recorded in the varieties Santa Monika, whose compound leaf length is 9.2 cm, Mathias 9.1 cm, Bella Rosa 10.8 cm and Cream Abundance 9.8 cm. The size of the leaf, its shape, color and gloss, are important for the overall impression of the planting object and determine the decorative value of the respective variety. Of all the varieties, Westpoint, Rotkappchen, Hans Gonewein, and Gebruder Grimm have the glossiest leaves. The bright shine together with dark green color of the leaves of these varieties make their bushes more expressive and bright and, therefore, more attractive for use in ornamental gardening. The results of the study are of practical importance, since they make it possible to select varieties that are valuable for ornamental gardening, not only in decorativeness of the flower, but also in the characteristics of their leaf appearance.

Commercial-biological estimation of the Paeonia lactiflora Pall. variety from the genetic collection of the Orenburg branch of the Federal Horticultural Research Centre for Breeding, Agrotechnology and Nursery

Peony lactiflorous (Paeonia lactiflora Pall) is one of the most common ornamental plants in commercial and amateur horticulture. The popularity of this species is explained by its adaptability to low temperatures in winter, high decorative value and the possibility of obtaining new sustainable varieties. This article presents data on 12 promising peony lactiflorous introduced varieties of the ornamental plant genetic collection of the Orenburg branch of the Federal Horticultural Research Centre for Breeding, Agrotechnology and Nursery (FRC of Horticulture) (Akron, Albert Crousse, Betty Groff, Madame Emile Lemoine, Madame de Verneville, Maestro, Ruth Clay, Sarah Bernhardt, Tulagi, Valencia, Waikik, Cruiser Aurora). The research was performed in 2018–2020 using conventional methods. To evaluate the influence of the genotype and climatic factors on the real seed production, the data were statistically processed, including a two-way analysis of variance. Upon evaluating the decorativeness, commercial-biological characteristics, introduced stability, it was established that these varieties are suitable for landscape gardening in the Orenburg region. Considering the set of metrics (high decorative value, phenological resistance, introduced prospects, commercial-biological value, varietal features), the Madame Emile Lemoine (double-flowered shape, diameter of 17 cm) and Akron (Japanese flower shape, diameter of 16 cm) varieties offer the combination of the most favourable characteristics for the steppe zone of the South Urals owing to their distinct flower scent, folious shoots, abundant flowering lasting for 13 days and over 3 flowers in the flower spike. The above varieties are characterised by the greatest real seed production (1,727.33±91.8 and 1,767.56±90.8 seeds/bush, respectively), high decorative value, stable phenophase, adaptivity to the sharply continental climate. Thus, further breeding work is recommended. The described peony lactiflorous varieties are promising and recommended for landscape gardening.

Sustainability and successful utilize of plants in gardens and landscape will be achieved by using proper plant in the right place. Hence landscape uses and aesthetical values of plants must be determined. Therefore, the present study were conducted to survey woody ornamental plants located in Cairo Festival City gardens, CairoGovernorate, Egypt through 2018 and 2019 as well as to determine their uses and values in terms of landscaping. Form beauty, ornamental foliage, ornamental fruit, ornamental flowers, and fragrance were took as aesthetical values parameters while landscape uses were recorded by the existing uses and potential uses of each plant. As a result of the study, totally 83 woody plant species belong to 33 families were recorded and they follow trees (40%), palms (12%), shrubs (41%), and vines (7%). Moreover, it has been found that Schinus molle, Plumeria alba, and Duranta erecta are attractive for four parameters of aesthetical value and the most of species are attractive for their ornamental foliage (32%). Also, Tecoma capensis, Cupressus sempervirens, Ficus benjamina, Plumbago auriculataare detected to be in nine different landscape uses and the most of species are recommended to be used as a specimen (68 species).

FEATURES OF THE INTRODUCTION INTO IN VITRO CULTURE AND MICROPROPAGATION OF PAULOWNIA TOMENTOSA

Paulownia sp. are tall and fast-growing perennial plants that grow faster than all woody plants in the world. In many countries, Paulownia sp. are used as a raw material in bioenergy, furniture industry, landscape gardening and technologies for phytoremediation. In this study for the first time in Kazakhstan, conditions of Paulownia tomentosa (P. tomentosa) in vitro cultivation and propagation have been optimized, also the factors influencing the morphogenetic activity of primary explants have been studied. Along with the adaptation potential of Paulownia tomentosa microclones to the ex situ conditions, laboratory standing order for microclonal reproduction have been evaluated. For sterilization of P. tomentosa explants are recommended to use 50% domestos and 0.1% merthiolate. Hormone-free WPM medium was considered as the most optimal for the in vitro propagation. Infrared light is highly recommended for P. tomentosa microclones adaptation, due to its ability to stimulate the formation plants aboveground biomass and root system. For Kazakhstan, the research of this type of tree crops is a relevant, new and promising direction. The development of microclonal propagation of Paulownia tomentosa will accelerate the process of introduction of Paulownia in our Republic.

Screens of the Picturesque: Aesthetics, Technology, Economy

The 18th-century notion of the picturesque is somewhat lesser known as compared to the more celebrated categories of the beautiful and the sublime, even though it may not only help us critically reflect upon modern perceptions of the landscape, but it may also provide us a unique way to link the field of aesthetic speculation with questions of technology and economy. The article will focus on two of the major theoreticians of the picturesque (William Gilpin and Uvedale Price) and will examine their ideas in relation to Edmund Burke’s aesthetics on the one hand, and contemporary tendencies in landscape gardening (as represented by Lancelot “Capability” Brown and Humphry Repton) on the other. Such an investigation may shed light on the multiple shifts in the perception of nature and the sense of naturalness during the long 18th century, as well as on the pictorial and theatrical aspects of landscape design. But examples of the Claude glass, the ha-ha, and Humphry Repton’s Red Books may also indicate the role of technological innovations and economic interests, and thereby the relevancy of the very discourse of the picturesque to more modern or even postmodern artistic, cultural, and medial developments.

Landscape gardening art of the Hellenistic states of Asia Minor

The article continues a cycle of publications of the author on Hellenustic landscape gardening art. The cultural region, which already in the most ancient times was a contact zone between the Greek world and the East is considered. The historical heritage of the Phrygian and Lydian kingdoms and the Persian Empire, which bequeathed to governors the Hellenistic era sacred groves, hunting reserves paradises and terrace parks with regular planning is traced. Special attention is devoted to parks of the Pontic kingdom of time of Mithridates VI Eupator’s government and parks of Pergamon. The country residence of Mithridates VI in Kabeira is interesting as a sample of the landscape park, the first in the history of the European landscape gardening art, at which there are motives characteristic for parks of time of Romanticism. Besides, parks in Kabeira and in Pergamon had unique collections poisonous and the herbs gathered by Mithridates VI and Attalus III. According to the author of article, these collections, besides utilitarian appointment, being raw materials for preparation of poisons and drugs, had aesthetic value, enriching park landscapes, and their natural qualities were intricately connected with mythology and religion of Greeks. Base of a research are the landscapes of the Black Sea coast of Turkey, the rich archaeological material saving up in one and a half centuries of excavations in Pergamon, and written sources, compositions of antique authors, among which are the works of poet and scientist 2nd century BC Nicander of Colophon not yet translated to Russian.
