Abstract. The purpose is to study the phenology, morphometry, reproductive biology, and propagation characteristics of the following species and samples of wild ramson onion: A. microdictyon Prokh. (Bashkir sample), A. victorialis L. (Moscow and Syktyvkar samples), A. ursinum L. (Moscow sample), A. ochotense Prokh. (Syktyvkar and Irkutsk samples). Methods. The study of wild ramson samples was carried out in 2016-2020 under the conditions of the culture in the South-Ural Botanical garden-institute of the UFRC RAS (Bashkir Cis-Urals, northern forest-steppe). The study of the seasonal rhythm of growth and development was carried out according to the method of phenological observations by I. N. Beideman and I. V. Borisova. Determination of winter hardiness and resistance to adverse weather conditions, pests and diseases, reproduction coefficient and seed productivity was carried out according to generally accepted recommendations. Results. According to the phenorhythmotype, the studied species are short-growing, spring-early-summer flowering. A. ursinum – ephemeroid, A. microdictyon, A. ochotense and A. victorialis – hemi-ephemeroid. The flowering phase occurs in late May-early June. The duration of flowering of wild ramson samples by year is 13-22 days. Seed maturation occurs in July. A. ursinum vegetation ends in July, the remaining samples-in August. The largest number of fruits and seeds are allocated samples of A. victorialis and A. microdictyon, the smallest – A. ursinum. Samples of A. microdictyon, A. ursinum and A. victorialis have a high percentage of fruit blooming. The weight of 1000 seeds of A. microdictyon is 3.6 g, A. ursinum – 5.9 g, A. victorialis – 6.3–6.7 g, A. ochotense – 7.9–8.5 g. Wild ramson seeds when sown in the open ground do not germinate in the same year: autumn sowing sprouts in 17–18 months, spring – in a year. To accelerate germination, it is recommended to stratify seeds for 2.5–3 months at a temperature of 0–3 °C. Scientific novelty. Research work on the study of wild ramson onions in the region of the Bashkir Cis-Urals has not yet been carried out. These species of onions have a wide resource value, which was caused by the high relevance of these studies.

The aim of the research is the assessment of 10 varieties of spring soft wheat approved for use, and 5 promising varieties of spring durum wheat of Russian selection according to yield and adaptability parameters for 2015-2018 on the basis of the results of the test carried out in the southern forest steppe zone of the Tyumen region. Productive and adaptive potential of the varieties was determined by the method of L.A. Zhivotkov co-authored, the average yield in contrast conditions –by the equations of A.A. Rossielle, J. Hemblin, the yield variability – by the method of B.A. Dospekhov, the environmental condition index and ecological plasticity of varieties – by S.A. Eberhart, W.A. Russell, the general adaptive ability of the varieties – by the method of A.V. Kilchevsky, L.V. Hotyleva. The strongest variability of indexes of environmental conditions during the years of testing of the varieties was found in middle-early varieties of spring soft wheat, from -1.08 (2017) to 1.26 (2018). The varieties of spring soft wheat Tyumenskaya Yubileynaya (middle-early, 3.06 t/ha) and Aviada (middle-season, 2.86 t/ha), and of spring durum wheat – Omsky izumrud (3.52 t/ha) were recognized the best in terms of average yield. In the favorable conditions of 2018, on the basis of determination of the percentage of yield of varieties relative to the average among the varieties, the largest productive potential of spring soft wheat varieties was revealed in Tyumenskaya Yubileynaya (middle-early, 111.5 %), Aviada (middle-season, 108.9 %) and spring durum wheat – Omskaya stepnaya (105.7 %). In the unfavorable conditions of 2017, high adaptability was observed in spring soft wheat varieties Ekaterina (middle-early, 118.7%), Ikar (middle-season, 105.0 %) and spring durum wheat – Omskaya stepnaya (105.8 %). Regardless of the specie, all studied varieties had significant yield variability. The most of the varieties were characterized as plastic (bi is equal to or close to 1). Strong responsiveness to change of conditions is determined in spring soft wheat varieties Novosibirskaya 15 (middle-early, bi = 1.11) and Aviada (middle-season, bi = 1.21), and in spring durum wheat Omsky korund (bi = 1.14). The varieties of spring soft wheat Ekaterina (middle-early, Si2 = 1.20), Tyumenskaya 29 (middle-season, Si2 = 0.03) and spring durum wheat Zhemchuzhina Sibiri (Si2 = 0.84) were the best in terms of stability. The varieties of spring soft wheat Tyumenskaya Yubileynaya (midlle-early, GAA = 0.32), Aviada (middle-season, GAA = 0.07) and the spring durum wheat Omsky izumrud (GAA = 0.26) were the best according to the general adaptive ability. The varieties of spring soft wheat Ekaterina (midlle-early) and Aviada (middle-season) and spring durum wheat Omskaya stepnaya were recognized as the best on the basis of the complex assessment of yield and adaptability parameters.

With the development of modern floral business, Callistephus chinensis (L.) Nees is among the top three of the most popular crops, yielding only chrysanthemum and calendula in commercial cultivation. This is one of the most widespread seasonal decorative annual flower crops, which is beautifully cultivated in open ground, pots and bouquet flowers. The researches presented in the article were conducted in order to determine the influence of weather conditions during the growing season of C. chinensis on the research sites of the educational scientific-production complex of the Sumy National Agrarian University (Northeast Forest-steppe of Ukraine) and the effectiveness of the application of various norms of complex mineral fertilizers, introduced at the planting of seedlings into open ground, on the processes of growth, flowering and other qualitative characteristics of the five varieties. During the growing season, the climatic conditions of the region of conducting research, variety characteristics, and also the variability of the parameters of height, number and diameter of C. chinensis inflorescences of the varieties 'Olenka', 'Leleka', 'Litnia Nich', 'Tsarivna' and 'Yabluneva' were influenced by variability mode of mineral nutrition. Weather conditions of vegetation have an impact on the number and size of inflorescences. According to research results, it has been established that there is a certain relationship between the weather conditions of the year and the number of inflorescences. So, the increase in the amount of precipitation during the growing season contributes to the development of the vegetative mass, but also negatively affects the formation of the number of inflorescences C. chinensis. For most varieties, the optimal conditions for the development of the generative sphere were the normal conditions for moisture of the year, and for the 'Litnia Nich' variety it was dry. The greatest increase in height when fertilizing compared to control was observed by the variety 'Tsarivna' (15.9 %), the smallest - by the variety 'Olenka' (2.0 %). The formation of inflorescences of greater diameter by the plants of the varieties 'Olenka', 'Litnia Nich' and 'Tsarivna' was observed in 2016, and by the 'Leleka' and 'Yabluneva' varieties in 2017. For most varieties in 2015, the diameter of inflorescences was the smallest. Studies have shown that weather conditions do not have a significant effect on the diameter of inflorescence, unlike mineral nutrition. The diameter of the inflorescences was the highest in comparison with the control by the variety 'Olenka' (18.3%), the smallest - by the variety 'Tsarivna' (1.1 %). The most valuable morphological and decorative features of C. chinensis plants of the five varieties under study were formed according to the norms of complex mineral fertilizers (nitroamofoska) 6.0 g/m2. The further increase of norm was not appropriate.

The paper states that it is necessary to expand the work in the field of ecological and geographical testing of economically valuable plant objects in the system of Botanical institutions supervised by the Council of Botanical gardens of Russia. The role of unique natural polygons of three Botanical gardens belonging to the Russian Academy of Sciences is emphasized. The main collection funds of the Nikita Botanical Garden are located in the Mediterranean climate zone (Yalta). In the Central Siberian Botanical Garden of Siberian Branch of Russian Academy of Sciences plants are introduced into the culture in the conditions of the continental climate of the forest-steppe of Western Siberia (Novosibirsk). In the Botanical Garden-Institute of Far Eastern Branch of Russian Academy of Sciences the gene pool of cultural and natural flora is studied in the monsoon climate (Vladivostok). The authors describe peculiarities of seasonal development, morphogenesis, organogenesis, ontogeny and reproductive biology of garden roses varieties of the Nikita Botanical Garden selection in three climatic zones. It is shown that in the geographical point of varieties breeding located near Yalta, the influence of climatic conditions leads to the absence of winter rest and natural end of the growing season - it is artificially regulated by the annual February pruning. In the monsoon climate of Vladivostok, the largest number of cloudless days (up to 80%) is observed in winter, which can not affect the vegetation of roses in the open ground, but has a beneficial effect on the development and cutting production of roses in greenhouses. In the forest-steppe of Western Siberia varieties from the groups of tea-hybrid, floribunda, grandiflora, Cordes roses and miniature throughout the study period did not enter the postgenerative period, the final ontogenetic state was g3. The main criterion for the selection of garden roses promising varieties in a continental climate is biomorphological - the ability of annual shoots to bloom. Breeding work with roses in the southern coast of the Crimea is carried out in the open ground, in the continental and monsoon climate - in greenhouses.

It is shown and proved then the first and mass seedling emergence 2 days faster due to cell 70 and 25 cm3 compere to cell 200 cm3 or direct sowing. Growth period from transplanting to budding of plants grown from cells 25 cm3 was 19 days only. It was shortest and 4 days earlier compere to plants from cell 200 cm3 or direct sowing. Longest growth period from transplanting to budding of plants was 30 days due to cassettes with cells 25 cm3. Plants from seedlings longer formed first yield. It was 44 days which was 7 days longer compere with direct sowing. The most active growth of foliage of the Basil plant observed before transplanting to open soil due to cells 200 cm3. The leaves surface was 242,7 cm 2. Plants which grown in cassettes with cells 70 and 200 cm3 had better biometric data. They were not depending from sowing and transplanting dates. It was indicated then with increasing of substrate volume seedling quality indicators increased as well. Most active process of leaf surface growth in basil plants took place in seedlings, which were grown in cassettes with a cell volume of 200 cm3 and before planting it in open ground, the leaf surface area was 242.7 cm2. Regardless of the time of sowing seeds and planting seedlings in the open ground, the best biometric indicators were plants grown in cassettes with a cell volume of 200 cm3, that is, with increasing food area per plant and seedling quality indicators increased. The longest peduncle (10,1 cm) had plants of second term of transplanting due to cells 70 and 200 cm3. Higher yield had plants grown from cells 70 and 200 cm3. Their yield was from 24,6 to 27,2 t/ha and depend of transplanting terms. Yield increase according to control was from 2,1 to 4,7 t/ha. Lowest yield shown plants which were grown in cassettes with volume of cells 25 cm3 from 23,4 to 25,3 t/ha.
