The range of most species of the genus Cotoneaster Medik. located in the mountainous regions of Asia.According to the latest report by Janette Fryer and Bertil Hylmo, the genus Cotoneaster is represented by 2 subgenuses,11 sections and 37 series. Cotoneasters of Siberian flora: C. commixtus, C. laxiflorus, C. lucidus, C. megalocarpus, C. multiflorus, C. popovii, C. tjulinae, C. uniflorus, C. yakuticus, located in 2 subgenuses, 4 sections, 4 series. Collection of speciesof the genus Cotoneaster in the Botanical Garden acad. A.V. Fomin was created according the method of genus complexesby F. N. Rusanov, starting from 1972. The source material was attracted both by the extraction of seeds from the catalogsof foreign and Russian botanical gardens, and by the collection of seeds and living material in places of natural growth.Two expeditions were carried out to the regions of Siberia. The first one – Yakutsk in 1982 (10.08 – 29.08) along the route Kiev – Novosibirsk – Irkutsk – Tomsk – Krasnoyarsk – Aldan – Irkutsk – Kiev. The second – Central Siberian in 1983(24.07 – 17.08) along the route: Kiev – Irkutsk – Davsha – Nizhne –Angarsk – Severo –Baikalsk – Ulan –Ude – Kyakhta –Irkutsk – Chita – Moscow – Kiev. Morphological descriptions of annual shoots leaves, flowers, fruits, seeds of three typesof Cotoneasters: C. laxiflorus, C. lucidus, C. neo-popovii, micrographs of endocarp of bones, columns are given. The material is illustrated with photographs of plants introduced in the north-west of Ukraine (Kiev).

The main task of the expeditions was the search for the following species of natural Siberian flora and theintroduction of live plants and seeds to the Botanical Garden named after acad. A. V. Fomin: Cotoneaster mongolicus.C. neo-popvii, C. tjulinae, which are currently presented in our collection. In addition, long-term phenological observations in the conditions of the north-west of Ukraine allowed to isolate new species from the imported material: C. kyachticus.C. logginovii. They are described in the materials of the XIV and XVII conferences “Problems of botany of Southern Siberiaand Mongolia”. A trip to the lake Zun-Torei was dedicated to the search for C. mongolicus. As it turned out later, under theC. mongolicus mother’s plant, we dug up a plant different from the mother’s plant, to which we gave the name C. logginovii.This article provides materials to identify the parents pair in the formation of this hybrid pitchfork. For this purpose,materials of herbarium collections from the vicinity of the lake were used Zun-Torei experienced local botanists, as wellas personal fees. Comparison of the samples allowed to establish their identity with C. mongolicus, as well as to certify it asone of the parents of C. logginovii. Morphological descriptions of annual shoots leaves, flowers, fruits, seeds of three typesof Cotoneasters: C. megalocarpus, C. mongolicus, C. yakuticus; micrographs of endocarp of bones of the previous speciesand C. logginovii, C. melanocarpus, C. uniflorus are given. The herbarium samples of C. mongolicus collected in the areaof the lake Zun-Torey were analyzed. The material is illustrated with photographs of plants introduced in the north-westof Ukraine (Kiev). The introduction of plants by the method of genus complexes by F. N. Rusanov allowed to create theCotoneaster collection, which includes 200 taxa of the genus. In the Botanical Garden named after acad. A .V. Fomin fromthe flora of Siberia preserved 11 species of Cotoneaster: C. commixtus, C. kyachticus. C laxiflorus. C. logginovii, C. lucidus,C. neo-popovii, C. megalocarpus, C. mongolicus, C. tjulinae, C. uniflorus, C. yakuticus.

Some results of cultivation of Siberian flora species in culture at the introduction nursery of useful plantsof the Peter the Great Botanical Garden of the BIN RAS, in St. Petersburg have been summed up. All species are classifiedaccording to biological resistance. The analysis of the introduction resistance of plants in Siberia showed that 83.3 % ofthe species adapted well to the new conditions of existence. According to the duration of the introduction experiment,all plants were divided into 5 groups. 37 % falls on the group of species, the life expectancy of which is more than 60years. 45 species of rare and endangered flora of Southern Siberia, grown in culture, have been identified, most of themcan be attributed to resistant (46.7 %) and highly resistant species (31.1 %). The maximum age of these plants in theexperiment reaches 68–84 years. The data obtained can be used to preserve and enrich regional flora and prepare materialfor repatriation work.

AbstractA summary of the techniques used and results obtained from three oversnow traverses in Marie Byrd Land and the Ellsworth Highland between January 1957 and January 1959 is presented. Seismic reflection shooting at 30 nautical mile (55.5 km.) intervals was combined with gravity, magnetic and altimetric measurements to determine the glacial and subglacial topography. It was found that a vast portion of West Antarctica has an ice–rock interface well below sea-level. A major connecting channel with a maximum depth of more than 2,500 m. below sea-level exists between the Ross and Bellingshausen–Amundsen Seas, whereas there is no major topographic connection between the Ross and Weddell Seas. This channel divides West Antarctica into two provinces with granite and rocks of sedimentary origin to the east and south, and a volcanic region to the north-west. Present ice flow is outward from two high areas, centred over mountainous regions on either side of the channel. It is concluded that the present ice sheet has grown from the convergence of the two smaller ice sheets which formed in the mountainous areas and joined across the intervening open water.

The region of Turkey whose Classical sites and monuments are discussed in this article lies wholly within the Western Taurus mountains, and consists of the eastern section of “the West Taurus Lake District”—as modern geographers now call it. The foothills of Taurus which extend around the south-western edge of the Konya Plain define both its northern and eastern limits; its western are established by the massive ranges which separate Lake Beyşehir from Lake Eğridir. Between these two mountainous regions, which join the main heights of Taurus further south, lies the rift valley occupied by Lake Beyşehir and the now partly-drained Lake Suğla.Here is to be found the borderland of Pisidia and Lycaonia, as indicated by Strabo. To the north-west and north lies Phrygia Paroreius; to the south, the borderland of Pamphylia and Cilicia Tracheia; and to the south-east, Isauria.

Вид Darmera peltata (Torr. еx Benth.) Voss характеризуется широким ареалом интродукции и культивирования во многих странах Западной и Северной Европы как красивоцветущее и декоративно-лиственное растение. Вид D. peltata имеет высокие показатели декоративности, в частности раннее и продолжительное цветение, многочисленные соцветия со светло-розовыми цветами, большие по форме и размерам листья, сохраняющие свою декоративность до заморозков. Усиленный интерес к этому виду связан с его экологической пластичностью: растения могут одновременно расти на затененных, влажных и переувлажненных участках. Введение в культуру растений D. peltata в г. Киеве сдерживают недостаточные сведения о биологической устойчивости растений к неблагоприятным факторам в течение осеннего, зимнего и весеннего периодов. Исследовалась зимостойкость растений D. peltata в условиях интродукции г. Киева. Изучались особенности культивирования растений в условиях открытого грунта. Объектами исследования служили растения D. peltata коллекционного участка Ботанического сада Национального университета биоресурсов и природопользования Украины. Морозостойкость растений D. peltata определяли методом прямого лабораторного промораживания по уровню повреждения корневища. Исследования проведены в лаборатории отдела физиологии растений Института садоводства НААН Украины согласно методике М.А. Соловьевой. Промораживание корней растений проводили при температуре -5, -8, -12 и -16 °С. Определено, что зимостойкость растений D. peltata обусловлена не только генетическими особенностями, но и состоянием подготовленности растений к зимнему периоду (время окончания роста осенью, условия питания растений в течение вегетационного сезона, поражение болезнями и вредителями). Погодные условия осеннего периода г. Киева характерны постепенным сокращением фотопериода и умеренным снижением температуры воздуха, что благоприятно для успешного перехода растений в состояние покоя и накопления ими питательных веществ. В течение зимнего периода не обнаружено таких явлений, как выпревание, вымокание и выпирание растений D. peltata из почвы. Сильные морозы и перепады температур воздуха не причинили существенных повреждений их корневищам, так как температура почвы в этот период оставалась относительно стабильной, обусловленной наличием снежного покрова. Результаты проведения лабораторного промораживания растений D. peltata свидетельствуют об их высокой, фактически потенциальной морозостойкости. Сделан вывод, что условия г. Киева вполне благоприятны для зимования растения D. peltata в открытом грунте. Species of Darmera peltata (Torr. ex Benth.) Voss is characterized by a wide areal of introduction and cultivation in many countries of Western and Northern Europe as a beautiful-flowering and decorative foliage plant. Species of D. peltata has high decorative performance, in particular, early and continuous flowering, numerous florets with light pink flowers, large in shape and size leaves that retain their decorative effect until frost. Enhanced interest by this species associated with its ecological plasticity: the plants can grow in the shade, wet and waterlogged areas at the same time. Introduction in culture plants of D. peltata in Kiev is limited by insufficient information about biological resistance of plants to adverse factors during autumn, winter and spring period. The purpose of work was researching the winter reistance plants of D. peltata in introduction conditions of Kyiv and the provisioning of information according to the features of cultivation of plants in open ground conditions. Winter resistance of D. peltata was studied in Kiev, located in the north of Ukraine. The objects of study were plants of D. peltata of the collection area of Botanical Garden of the National University of Life and Environmental Sciences of Ukraine. Frost resistance plants of D. peltata was determined by direct laboratory freezing the level of damage to the roots. Researches was made in the Laboratory of Plant Physiology of the Institute of Horticulture NAAS of Ukraine according to the method of M.A. Solovieva. Freezing plant roots was carried out at the temperature of -5, -8, -12 and -16 °C. It was determined that the winter resistance plants of D. peltata depends not only on genetic characteristics but also the state of preparing plant to the winter period (the end time of growth in autumn, the conditions of plant food during the growing season, a defeat diseases and pests). The weather conditions of autumn period in Kiev characterized by a gradual reduction of photoperiod and moderate decreasing of air temperature that is favorable to their successful transition to the resting state, and the accumulation of nutrients. Researching the plants of D. peltata during the winter period is not found out such phenomena as the damping-off, waterlogging and bulging the plants from the soil. Heavy frosts and air temperature changes did not cause significant damage to rhizomes of plant D. peltata, as the soil temperature during this period remained relatively stable due to the presence of snow. The results of the laboratory freezing plants of D. peltata show about the high actual and potential frost resistance. That is why, the conditions of Kiev is quite favorable for wintering plants of D. peltata in the open ground.
