Potential volume of planting material market for ornamental crops was calculated based on the analysis of master plans for the development of Crimean cities taking into account standards for planting trees and shrubs. Data were obtained on territorial belonging, purpose, production cycle, and range of peninsula nurseries. It was proposed to use plus trees growing in urban conditions as mother trees for production of planting material adapted to the urban ecological and climatic conditions of this area. We have previously proposed a basic recommended assortment to green the Piedmont zone of Crimea. On its basis a GIS of plus trees of large landscape objects of Simferopol was developed.

Одним из факторов повышения урожайности и рентабельности плодовых насаждений является использование клоновых подвоев, экологически адаптированных к природным условиям региона, устойчивых к стрессовым факторам, а также хорошо совместимых с большинством сортов. В статье представлены результаты исследований за 2009-2014 гг. по уточнению элементов технологии выращивания посадочного материала груши в условиях Крыма. Проведен анализ полученных данных сравнительного изучения перспективных и районированных клоновых подвоев для груши (ВА-29, ИС 2-10, КА 53, КА 86, КА 92) с сортами (Бере Арданпон, Изумрудная, Изюминка Крыма, Мария, Мечта, Отечественная, Таврическая) адаптированными для почвенно-климатических условий Крыма. Изучено их влияние на рост, развитие и выход саженцев. Исследуемый набор отвечает требованиям современного садоводства. Интенсивные насаждения необходимо закладывать стандартным посадочным материалом, отвечающим современным требованиям. Цель исследований - дать оценку подвоям и сорто-подвойным комбинациям груши в питомнике по комплексу хозяйственно-биологических признаков и выделить перспективные для совершенствования сортимента Крыма и юга России. В проведенных исследованиях в питомнике, по основным параметрам выделены подвои крымской селекции серии КА. Средний выход стандартных однолетних саженцев на исследуемых подвойных формах составил 77-85%.One of fruit yield and profitability drivers is the use of clonal rootstocks that have been environmentally adjusted to the natural conditions of a region. These rootstocks also must be resistant to stress factors and well-compatible with most varieties. The paper reports results of research of 2009-2014 aimed to clarify the elements of planting material cultivation technology in the conditions of the Crimea. We analyzed data of a comparative study of rootstock-scion combinations of promising and released clonal rootstocks for pear (VA-29, IS 2-10, KA 53, KA 86, KA 92) and pear varieties (‘Bere Ardanpon’, ‘Izumrudnaya’, ‘Izuminka Kryma’, ‘Mariya’, ‘Mechta’, ‘Otechestvennaya’, ‘Tavricheskaya’) that were adapted to the soil and climatic conditions of the Crimea, including Crimean breedings. The effect of the rootstocks on the growth, development and output of seedlings was studied. The study set meets requirements of modem horticulture. Intensive plantings should be established with a standard planting material that meets modern requirements. The goal of the study was to evaluate pear rootstock-and-scion combinations in the nursery based on a number of economic and biological traits and to reveal those promising for improvement of fruit assortment in the Crimea and in the south of Russia. As a result, ‘KA’ series rootstocks bred in the Crimea were sorted out for main parameters. The average output of standard yearlings on the study rootstocks was 77-85%.

Яблоня гибридная (M. hybrida) объединяет гибриды и сорта на основе яблони Недзвецкого с необычной формой кроны, окраской цветков, листьев и плодов. Для расширения ассортимента озеленительных посадок Екатеринбурга необходим районированный посадочный материал с низким или средним уровнем изменчивости фенотипических признаков цветения и плодоношения. Цель работы – отбор форм яблони гибридной в озеленительных посадках Екатеринбурга по качественным и количественным признакам лепестков венчиков, цветков и плодов. На 15 объектах озеленения у ценных в селекционном отношении форм яблони определены длина и ширина лепестков венчика. На 11 объектах у отборных особей яблони установлены диаметр, масса, форма, цвет плодов и длина плодоножки. Уровень изменчивости фенотипических признаков декоративных таксонов яблони оценивался по эмпирической шкале уровней изменчивости. При отборе образцов яблони наиболее декоративными считаются особи с ярким и продолжительным цветением. Разнообразные форма и цвет плодов позволяют декоративным таксонам яблони быть привлекательными более длительное время. У исследуемых нами внутривидовых форм окраска лепестков венчика варьирует от бело-розового до темно-пурпурного. Средний уровень эндогенной изменчивости по ширине и длине лепестков венчика указывает на устойчивость форм яблони гибридной к условиям города по данным фенотипическим признакам. Повышенный уровень изменчивости массы плодов у некоторых форм указывает на нестабильность данного признака в условиях города, что приводит к отсутствию в плодах семян, их недоброкачественности или низкой всхожести. Перспективные по декоративности формы яблони гибридной размножают прививками. Многолетние озеленительные посадки из полиморфных деревьев яблони гибридной, устойчивых к местным климатическим условиям, являются источником для создания маточных коллекций в питомниках Урала. Методами аналитической селекции (получение сеянцев от свободного опыления) можно отобрать адаптированные к объектам озеленения зимостойкие декоративные таксоны яблони с яркими фенотипическими признаками. The hybrid apple tree (M. hybrida) combines hybrids and varieties based on the Nedzwiecki apple tree with an unusual crown shape, coloring of flowers, leaves and fruits. To expand the range of landscaping plantings in Yekaterinburg zoned planting material with a low or medium level of variability of phenotypic signs of flowering and fruiting is required. The purpose of the work is to select the forms of hybrid apple tree in the landscaping plantations of Yekaterinburg by the qualitative and quantitative characteristics of corolla petals, flowers and fruits. The length and width of the corolla petals have been determined for 15 planting objects of valuable for selective breeding apple tree forms. The diameter, weight, shape, color of the fruit and the length of the peduncle were determined on 11 objects in selected individuals of apple trees. The level of variability of phenotypic traits of decorative apple taxa was rated using an empirical scale of levels of variability by S.A. Mamaev (1973). When sampling apple trees, individuals with a bright and long flowering are considered the most decorative. Various shapes and colors of fruits allow the decorative taxa of the apple tree to be attractive for a long time. In the forms of hybrid apple tree that we studied, the color of the corolla petals varies from white-pink to dark purple. The average level of endogenous variability in the width and length of the corolla petals indicates the resistance of the hybrid apple tree forms to urban conditions according to these phenotypic traits. An increased level of variability in the mass of fruits in some forms indicates the instability of this trait in urban conditions, which leads to the absence of seeds in the fruits, their poor quality or low germination. Selective breeding forms of such crops are propagated by grafting. To obtain apple taxa adapted to local conditions, it is necessary to propagate by seeds and obtain seedlings from free pollination with bright phenotypic traits. Perennial landscaping plantings of polymorphic hybrid apple trees, resistant to local climatic conditions, are a source for creation of plantations in nurseries of the Urals as a source of varietal planting material.

<p>The purpose of our work is to assess the health state of woody plants growing in different habitats of the city of Aktobe. We have studied the health state of arboreal and shrubby plants growing in various urban habitats; the survey was conducted during 2016-2017 by route-visual method. We performed the analysis of species diversity, abundance and density in urban area. The assessment of health state of the trees was made according to V.A. Alekseev. From your data and literature review we established that such species as Ulmus pinnato-ramosa, Acer negundo, Populus tremula, Populus nigra, and Syringa vulgaris have strong winter resistnce in the territory of Aktobe; we registered that only their apex buds and emds of the shoots were frozen in severe winters. The medium-resistant speices include Ulmus laevis and Acer platonoides. They are less plastic and suffer from late spring and early autumn frosts. The Amorpha fruticosa, Vitis vinifera, and Parthenocissus guinguefolia could be considered as the non-resistant species, since they usually freeze up to the snow cover line. The analysis of the vital state made it possible to assess the resistance to urban conditions of the majority of trees and shrubs registered in urban habitats of Aktobe. According to the preliminary data, the origin of the plant and its winter resistance are of main importance when introducing new species to urban area.</p>

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.

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.

One of the features that characterise the designated capital city of Dodoma is the limited green landscape element as a result of semiarid climatic conditions of the whole central region of Tanzania. Besides concerted efforts by the Dodoma urban authorities to develop greenery landscape within the city through the Capital City Development Programme, such efforts have fallen into conflict with people’s livelihood activities. In this paper, it is argued that the gap between identification of appropriate landscape features that are not consistent with people's lifestyles and the local conditions are the contributory factors to the observed conflicts between attempts to green the city and livelihoods of the residents. Borrowed planning concepts in the masterplans thatwere imposed on the contextof Dodoma do not reflectthe realityof thepeople's needs and priorities as regards their livelihoods. These concepts have to the greatest extent failed to integrate livelihood activities and greening initiatives. This paper underscores the need for developing locally based planning considerations that take cognisance of all stakeholders and the local context as a way towards harmonising greening initiatives while accommodating people's livelihood needs and activities.Key Words: greening initiatives, livelihood activities, semi-arid cities, urban planning, master plans, Dodoma, Tanzania.

Abstract. A high-resolution, continuous 18.5 kyr (1 kyr  =  1000 cal yr BP) macroscopic charcoal record from Qinghai Lake in southwestern Yunnan Province, China, reveals postglacial fire frequency and variability history. The results show that three periods with high-frequency and high-severity fires occurred during the periods 18.5–15.0, 13.0–11.5, and 4.3–0.8 ka, respectively. This record was compared with major pollen taxa and pollen diversity indices from the same core, and tentatively related to the regional climate proxy records with the aim to separate climate- from human-induced fire activity, and discuss vegetation–fire–climate interactions. The results suggest that fire was mainly controlled by climate before 4.3 ka and by the combined actions of climate and humans after 4.3 ka. Before 4.3 ka, high fire activity corresponded to cold and dry climatic conditions, while warm and humid climatic conditions brought infrequent and weak fires. Fire was an important disturbance factor and played an important role in forest dynamics around the study area. Vegetation responses to fire after 4.3 ka are not consistent with those before 4.3 ka, suggesting that human influence on vegetation and fire regimes may have become more prevalent after 4.3 ka. The comparisons between fire activity and vegetation reveal that evergreen oaks are flammable plants and fire-tolerant taxa. Alnus is a fire-adapted taxon and a nonflammable plant, but density of Alnus forest is a key factor to decide its fire resistance. The forests dominated by Lithocarpus/Castanopsis and/or tropical trees and shrubs are not easy to ignite, but Lithocarpus/Castanopsis and tropical trees and shrubs are fire-sensitive taxa. Fire appears to be unfavourable to plant diversity in the study area.
