The paper contains results of introduced study of species, hybrids and sorts of Deutzia Thunb. genus in the South-Ural botanical garden-institute (Ufa). The collection of Deutzia is one of the largest among ornamental shrubs in the botanical garden. The objects of researches were 12 species, 10 hybrids and sorts of Deutzia . Introduced researches of all taxons were conducted within 10 years (2007-2017). Throughout the entire period of observations the following indicators were annually estimated: lignification of escapes, winter hardiness, preservation of a form of growth, sprout-formation ability, a gain in height, generative development, possible ways of reproduction in the culture. The analysis of the obtained data shows that specific taxons are belong to three groups: quite perspective, perspective and less perspective. The greatest possible indicators characterize 3 species - D. amurensis , D. glabrata, D. parviflora . All of them can be recommended for broad application in gardening of settlements of the Bashkortostan Republic. Perspective and less perspective groups contained 4 species each. Hybrids and sorts in the collection belong to three groups: perspective (II), less perspective (III) completely unusable (VI); in the latter group contains one hybrid.

Mountain ash (Sorbus aucuparia L.) is a valuable medicinal and food plant that is widely used in practical medicine and in amateur horticulture. The purpose of this study was to determine the content of ascorbic acid, organic acids, tanning substances and flavonoids in the fruits of some representatives of the Sorbus genus of the collection of the South-Ural Botanical Garden-Institute and to identify the most promising taxa. For analysis, fruits were collected in the full ripening phase and dried to air-dry state. Phytochemical studies were carried out according to conventional methods. The object of comparison was the official pharmacopoeia species – Sorbus aucuparia. Analysis of the obtained data found that the fruits × Sorbocotoneaster pozdnijkovii and Sorbus sibirica outperformed the natural form (Sorbus aucuparia) in terms of ascorbic acid content by 11.54 and 43.27%; Organic acids by 24.11 and 60.84%; Tanning substances by 3.49 and 43.23%; Flavonoids by 44.19 and 12.79%, respectively. The obtained results allow to recommend these taxa as promising sources of raw materials for production of biologically active substances in production of natural food products and food additives.

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.

The mound of Kilindir (fig. 1) lies about one kilometre south-west of the station of that name on the railway that runs from Salonika to Constantinople via Seres, Dedeagatch and Adrianople. A small stream called Gyol Ayak issues from the south side of Lake Doiran exactly at the modern village at Doiran station. This stream, after passing through nine kilometres of broken and ravined country, issues into more open ground just by the modern Chiflik which represents the pre-war site of the village of Kilindir.

In September 1999, royal ferns (Osmunda regalis L.) at a South Carolina wholesale nursery were found to be infected by foliar nematodes. Lesions were brown, vein-limited, and often fan shaped. As severity increased, affected leaflets became totally necrotic. Nematodes were extracted by excising and dicing symptomatic leaf sections and placing them in water for up to 24 h. Ten adult nematodes from each of two fern plants were examined microscopically and determined to be Aphelenchoides fragariae (Ritzema Bos) Christie. This is the first report of this nematode infecting royal fern. In August 1996, leaves from several cultivars of Hosta spp. with yellow to tan, vein-limited lesions were submitted from The South Carolina Botanical Garden (Clemson, SC) to the Clemson University Plant Problem Clinic for diagnosis. Nematodes were extracted and examined as described above and identified as A. fragariae. This is the first report of this nematode infecting Hosta spp. in South Carolina. Since 1996, foliar nematodes have been recovered from hostas at several wholesale nurseries in South Carolina. Aphelenchoides spp. also have been detected previously in commercially produced ornamental plants in South Carolina, including a Begonia sp. in 1988; Polygonum bistorta L. ‘Super-bum’ (snakeweed) in 1997; and a Polystichum sp. (holly fern) in 1997. All plants exhibited angular or vein-limited, necrotic lesions typical of foliar nematode infections.

The morphology and sowing qualities of 7 types of hydrangea from the collection of the South Ural Bo-tanical Garden-Institute of the UFIC RAS were studied. The studies were carried out according to stand-ard methods. Is determined the mass of 1000 pieces seeds of each species, seed quality (germination en-ergy and germination in laboratory and soil conditions), the nature of seed germination, as well as their sowing qualities after different storage periods. It was found that the representatives of the Heteromallae subsection are characterized by heavier and larger seeds (the maximum weight of 1000 pieces of seeds is 0.06-0.09 g) compared with the representatives of the Americanae subsection (weight of 1000 pieces is 0.02 g). In addition, representatives of the Heteromallae subsection, with the exception of H. paniculata, showed consistently high rates of germination (72.3-85.8%) and germination energy (63.3-78.1%) under laboratory conditions; with soil sowing, these indicators are also significantly higher than that of repre-sentatives of the Americanae subsection.
