Representatives of the genus Hortensia (Hydrangea L.) are ornamental shrubs that are highly valued in landscape construction. Today, it is important to create new and reconstruction of existing recreational areas for the recreation of the population. This leads to an increase in the demand for ornamental trees and shrubs as a material for green building. In the Middle Urals, the species of Hydrangea are still rarely used due to the poor knowledge of the bioecological characteristics of various species and varieties under the given growing conditions. The paper gives a characteristic of varying degrees of adaptability to unfavorable abiotic and biotic environmental factors of 14 species and varieties of Hydrangea (Hydrangea) from the collection of the Department of Plant Introduction and Acclimatization, which was planted on the territory of the UdmFIC UB RAS in Izhevsk in 2017. For decorative features, a technique developed by the staff of the Botanical Garden of Ufa was used. Methodological developments on decorativeness of various cultures are taken as a basis. The characteristics of meteorological conditions during the years of research (2019-2020) are given. According to the research results, 7 representatives of the Hydrangea genus were noted as the most promising candidates for green construction in the cities of the Middle Urals. Hydrangea paniculata (H. Paniculata): ‘Lime Light’. ‘Pinkie Winky’, Weems Red ’, Vanilla Fries’. Hydrangea serrata (H. Serrata) 'Bluebird', Hydrangea petiolar (H. petiolaris) and hydrangea tree (H. arborescens). According to the results of two years of observation (2019-2020), these taxa had a decorativeness rating of 50 to 73 points and were assigned to the II group of decorativeness, winter hardiness (5 points). It was noted that unfavorable climatic conditions (moisture deficit, cool May and June 2020) reduced the average decorative score of the entire collection of representatives of the genus Hydrangea by 10 points. This was mainly due to the quality of the flowering.

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.

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.

In the process of plant introduction, the main task is to study the features of their biology and ecology, and as a result, their adaptive capabilities in specific climatic conditions. In nature, species of iris ( Iris L.) are widely distributed from the Northern regions to the subtropics and have a great ecological plasticity. In the conditions of the Stavropol upland, it is possible to successfully grow representatives of the genus iris from different parts of its range. The collection of irises in the Stavropol Botanical garden has 19 species. Species of Iris furcata, I. notha, and I. pumila that are common in grass-turf and meadow steppes, and I. pseudonotha that are common in wet meadows, have a stability in the conditions of culture, and they have an annual abundant flowering and fruiting. The timing of the beginning of generative phases of I. pumila development in culture and natural populations of the Stavropol upland varies within 5-7 days. In comparison with other species of local flora in the collection I. pseudonotha is most susceptible to diseases, for species I. halophila flowering is not observed every year. Some of the species in the collection are of Far Eastern Asian origin: I. domestica, I. ensata, I. lactea, I. laevigata, I. oxypetala, I. sanguinea and North American - I. versicolor. Among them, I. domestica shows the least frost and drought resistance, the flowering of the species occurs during the hottest period - the third decade of July, however, in some years, high seed productivity was observed for the species. Irregular flowering in the I-II decade of May was observed for I. lactea and I. oxypetala. The species I. ensata blooms in early June, a month earlier than in natural populations. Most of the Iris species in the collection are stable, and to a lesser extent adaptive potential is shown by species with a narrow ecological and phytocenotic affiliation - I. domestica, I. scariosa, I. halophila, and I. lactea . Species I. pseudonotha, I. domestica, and I. graminea do not reach their natural values in terms of habitus.

Representatives of the genus Pentaphylloides are low ornamental shrubs that are valued for long abundant flowering, compact size and unpretentiousness to growing conditions. P. fruticosa is a valuable plant that has not only decorative value, but also food, medicinal, soil protection. For medicinal purposes, young flowering shoots are used, harvested during budding and flowering. The article presents the results of phenological observations in 2018-2020. The objects of the study were plants of 8 kinds of Pentaphylloides in the collection of the Botanical Garden-Institute of Volga State University of Technology (Yoshkar-Ola, Mari El Republic). The studied plants undergo most phases of seasonal development, with the exception of the mass end of shoot growth, complete lignification of shoots, mass ripening of fruits, mass leaf fall. Species and cultivars vegetated from the end of April – the beginning of May to the end of October in a short time. The vegetation period was 177-182 days. There was no significant difference in the timing of the passage of phenophases between the taxa. Plants of Р. × friedrichsenii and P. mandschurica passed most of the phenophases earlier than the average dates for the genus, and 'Goldfinger' and 'Klondike' – later. The earliest and longest flowering was characterized by P. friedrichsenii (65 d.), the latest and shortest – P. fruticosa (28 d.). All plants of P. fruticosa cultivars bloomed for a longer period than the species. After mass flowering, single flowers were observed in representatives of Pentaphyloides until mid-October.

Abstract Due to the lack of maintenance, abandoned cemeteries are often incorporated into the landscape. In many cases the information about the age of the cemetery is unavailable. To find out the approximate time of the formation of the cemetery the information recorded in the annual tree and shrub rings can be used. One of the most common tree species, planted for ornamental and symbolic purposes on the cemeteries, are Thuja orientalis and Thuja occidentalis. Alien to the Polish flora, these species adapted well to the local habitat and climatic conditions. The paper presents an attempt to apply dendrochronological dating to determine the age of the abandoned cemeteries in the region of the Great Masurian Lakes, part of the Masurian Lake District (north-eastern Poland). The study included five abandoned cemeteries. In total, 15 cores were taken from the trees. After applying the standard dendrochronological method, local chronologies for the studied species were established. The research indicated that the oldest found specimens - over 70 yrs old - are Thuja occidentalis individuals growing at the Słabowo cemetery. At the other sites the specimens of both Thuja species date back to the 1960s and early 1970s. Compared to the historical information regarding the age and origin of the studied objects, thujas growing there are much younger than the age of the cemeteries foundation. The presented method proved to be very helpful in understanding the time of Thuja occidentalis and Thuja orientalis introduction at the investigated cemeteries.

First Results

Research subject. The article presents the results of dating two dolerite dikes differing in geochemical features from a section along the Iset river in the area of Smolinskoe settlement (the Eastern zone of the Middle Urals). Materials and methods. The dating was performed by an U-Pb ID-TIMS technique for single zircon grains using an artificial 205Pb/235U tracer in the laboratory of geochronology and isotope geochemistry of the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences. The lead isotopic composition and uranium and lead concentrations were measured using a Finnigan-MAT (RPQ) seven-channel mass spectrometer in dynamic mode using a secondary electron multiplier and RPQ quadrupole in ion counting mode. Results. The dikes were dated 330 ± 3 Ma and 240 ± 2 Ma. Conclusions. The research results indicate different ages of dolerite dikes developed within the Eastern zone of the Middle Urals. The oldest of the two established age levels corresponds to the Early Carboniferous era. This fact, along with the proximity of the dolerites to the petrochemical features of the basaltoids of the Early Carboniferous Beklenischevsky volcanic complex, allows these bodies to be considered as hypabyssal comagmates of these volcanics. The youngest obtained age level – Triassic – indicates that the introduction of some dolerite dikes was associated with the final phases of the trapp formation developed rarely within the eastern outskirts of the Urals and widely further east in the foundation (pre-Jurassic basement) of the West-Siberian Plate.

The article presents the results of studying the diversity of pear rootstock forms in terms of yield and seed productivity. The research was carried out at the experimental sites of the Orenburg Experimental Station of Horticulture and Viticulture of AllRussian Horticultural Institute for Breeding, Agrotechnology and Nursery and the Botanical Garden of the Orenburg State University in 2017-2019, in typical soil and climatic conditions of the Orenburg city. The purpose of the study is to identify pear rootstock forms characterized by high yield and stable seed productivity for use in the future as a seed rootstock. During the research, 15 pear accessions were studied; the planting scheme was 6x4 m. As a result of research, it was found that the rootstock form Temno-zelenaya is characterized by a high yield (40 kg/tree). High seed productivity of more than 6 seeds in one fruit was observed in samples: Vernaya (6.0-6.5 pcs.), SK-1, SK-3 (6.1-7.8 pcs.), SK-2 (7.0-7.5 pcs.), Chang Bai Li (7.4-7.7 pcs.), Semennaya 214 (7.5-7.8 pcs.). It was revealed that the Xiao he Bai Li variety is characterized by the maximum weight of 1000 seeds (65.2 g). Analysis of accessions by seed yield established that a consistently high yield is observed in the varieties Chang Bai Li (2.5-4.2 %), Vernaya (3.96-4.18 %) and forms SK-1 (2.0-3.25%), SK-2 (2.25-2.75 %), SK-3 (1.43-4.0 %). Pear rootstock forms Chang Bai Li, Vernaya, Semennaya 214, SK-1, SK-2, SK-3 were identifi ed, which can be recommended for production testing as seed pear rootstocks for the conditions of the steppe zone of the Southern Urals.
