Climate change affects the possibility of crop production and yield and disrupting the maintenance of crop biodiversity, including ornamentals. Warsaw is located in a temperate zone with mixed continental and oceanic climate influences. This research examines the response of once-blooming rambler roses to changing climate conditions in connection with their frost resistance and ornamental value. The 15 selected rambler rose cultivars were observed in the years 2000–2016 in the Polish Academy of Sciences Botanical Garden—Center for Biological Diversity Conservation in Powsin. Damage to shrubs caused by frost, the timing of bud break, leaf development, and initial, full, and final flowering were recorded. We show that changes in phenology and frost damage were the effect of weather conditions in the autumn–winter–spring period. Frost damage influenced the flowering and growth of plants in different ways, depending on the extent of required pruning. The cultivars most highly tolerant to frost damage were: “Lykkefund”, “Polstjårnan”, and “Semiplena”. During the final years (2014–2016), due to mild winters, all of the studied rose cultivars could be used for a wider range of applications than previously (2000–2006 and 2009–2013). Their reintroduction helped to maintain biodiversity of old cultivars, which makes these roses a proposal for the lowlands of Central Europe.

Fruiting is an important characteristic of plant adaptation to new growing conditions. This is especially actual for ornamental plants, which, after successful introduction, can be used in landscaping of settlements. The genus Syringa L. has about 30 species, many of which can replenish the range of ornamental plants in the region. The collection of lilacs of the South Ural Botanical Garden-Institute of the UFIC RAS (Ufa Federal Research Centre of Russian Academy of Sciences) currently contains 11 species that have reached a generative state. The aim of this research is to identify the features of fruiting species of the genus Syringa during introduction in the conditions of the Bashkir Cis-Urals. The fruiting level of lilac species in the collection of the Botanical Garden was studied by determining the total number of fruits of the mother bushes. It is revealed that the fruiting level of introduced species of lilac is determined by the biological (hereditary) characteristics of the species and seasonal changes of weather conditions. S. velutina is characterized by the highest fruiting level, S. vulgaris and S. wolfii – by the lowest ones. It is assumed that there might be a tendency for dependence of the degree of fruiting on the quality of the formed pollen. Two taxa among all studied ones demonstrate fruiting level instability: S. reticulata ssp. reticulata blooms and bears fruit irregularly, while S. reticulata ssp. amurensis has regular abundant flowering, but there is a lack of fruiting in some years.

Aim. The aim of the work was to evaluate the anti-radical activity of extracts of ginseng's underground and overground organs Panax ginseng C.A. Mey, depending on various factors – age of plants, collection time and cultivation conditions. Methods. Extracts obtained from various plant organs were evaluated in the model system with cation-radicals ABTS. At the same time, the amount of extractive substances and phenolic compounds was determined. Results. Samples of leaves and roots of ginseng of 1, 2, 3, 5, 9 years of vegetation from the collection of the Central Botanical Garden of the National Academy of Sciences of Belarus were analyzed. It is established that extracts of ginseng leaves of P. ginseng can be considered as sufficiently effective anti-radical agents. Anti-radical activity of extracts of roots and leaves of ginseng differed significantly depending on the weather conditions of the growing season. Conclusions. It is shown that extracts of ginseng leaves differ by the maximum antiradical activity. Extracts of ginseng roots showed a much lower anti-radical activity in comparison with leaf extracts, which may be due to both a smaller amount of extractives extracted from water-ethanol extraction and their composition. Keywords: ginseng, antiradical activity, phenolic compounds, extractives.

The genetic pool of valuable old ornamental cultivars and their in situ maintenance may be threated by climate change. Meanwhile, the ornamental plants like roses make up an important share of both gardens and urban green spaces, where they are particularly vulnerable to multistress growth conditions. The aim of this research was to evaluate the effect of changing climatic conditions on growth and flowering of 11 historic climber roses through long-term studies (2000-2017) conducted in Central Europe. The evaluation of plants consisted of assessment of frost damage and the timing of early phenological stages (starting of bud break, leaf unfolding) as well as gathering data on beginning, fullness and end of flowering and its abundance. Frost damage was not recorded in any year only in ‘Mme Plantier’, and did not occur for any cultivar after the winter in the years 2007, 2008, and 2014. Only a little damage to one-year shoots was recorded after the winter in the years 2015-2017. Frost damage to ‘Alberic Barbier’, ‘Albertine’, ‘Chaplin's Pink Climber’, ‘Orange Triumph clg’ and ‘Venusta Pendula’ led to pruning to ground level in every year excluding those listed above. Frost damage of once blooming roses limited their flowering; however, the many-year data-sets showed a trend for decreased frost damage and improved abundance of flowering, and these results can be interpreted as a response to the increase of average air temperature. The timing of bud breaking and leaf development in all climber roses was strictly correlated with average air temperature in the dormancy period. The reactions of climber roses to weather conditions confirmed the influence of climatic changes on ornamental crop plants in Central Europe, introducing the potential possibility for the wider application of climber roses, but without certainty of flowering every year.

The current paper has given the study results of spring triticale samples grown under the conditions of the field experimental station of the Russian SAU – MAA named after K. A. Timiryazev and the department of remote hybridization of the Main Botanical Garden named after N. V. Tsitsin in 2017–2018. There have been studied 10 varieties of domestic and foreign selection, as well as 10 breeding lines developed with the authors’ participation. The trial and analysis of the results have been performed according to the method of State Variety Testing of agricultural crops. There have been presented the results of grain quality assessment in contrasting weather and climate conditions of 2017–2018. The weather conditions in 2018 were favorable for the formation of better grain in comparison with 2017. Almost all samples showed greater indices of protein and gluten content, gluten quality, kernel hardness, falling number and bread volume in 2018 that these in 2017. At the same time, there was seen productivity decrease. In general, according to the study results over two years, there were identified the spring triticale sample “Dublet” and the breeding lines “131/1656” and “C 259” as the most productive and capable to give stable yields of more than 50 kg/ha; with good adaptability and grain quality. The varieties “Lana”, “Sandro” and the breeding lines “131/7”, “C 259”, “6-35-5” and “P2-13-5-2” showed a high protein and gluten content compared to the standard variety “Ukro”. There has been identified a negative value of the correlation between the indicators of protein content and grain yield (r = –0.54), gluten content and yield (r = –0.61). The identified samples could be used in the breeding programs for better yields and good grain quality.

Changing Climate

The populations, species, and communities in high elevation mountainous regions at or above tree line are being impacted by the changing climate. Mountain systems have been recognized as both resilient and extremely threatened by climate change, requiring a more nuanced understanding of potential trajectories of the biotic communities. For high elevation systems in particular, we need to consider how the interactions among climate drivers and topography currently structure the diversity, species composition, and life-history strategies of these communities. Further, predicting biotic responses to changing climate requires knowledge of intra- and inter-specific climate associations within the context of topographically heterogenous landscapes. Changes in temperature, snow, and rain characteristics at regional scales are amplified or attenuated by slope, aspect, and wind patterns occurring at local scales that are often under a hectare or even a meter in extent. Community assemblages are structured by the soil moisture and growing season duration at these local sites, and directional climate change has the potential to alter these two drivers together, independently, or in opposition to one another due to local, intervening variables. Changes threaten species whose water and growing season duration requirements are locally extirpated or species who may be outcompeted by nearby faster-growing, warmer/drier adapted species. However, barring non-analogue climate conditions, species may also be able to more easily track required resource regimes in topographically heterogenous landscapes. New species arrivals composed of competitors, predators and pathogens can further mediate the direct impacts of the changing climate. Plants are moving uphill, demonstrating primary succession with the emergence of new habitats from snow and rock, but these shifts are constrained over the short term by soil limitations and microbes and ultimately by the lack of colonizable terrestrial surfaces. Meanwhile, both subalpine herbaceous and woody species pose threats to more cold-adapted species. Overall, the multiple interacting direct and indirect effects of the changing climate on high elevation systems may lead to multiple potential trajectories for these systems.

Abstract Among the 2750 species of the Polish vascular flora, about 500 species are threatened with extinction and 430 of them are strictly protected by national law. The FlorNatur project for the ex situ conservation of the most endangered species was started in 2009. The aim of the project is to collect seeds of 61 species from 161 sites in eastern Poland and store them in the Seed Bank of the Polish Academy of Sciences Botanical Garden - Center for Biological Diversity Conservation in Warsaw- Powsin. A complementary program is being carried out by the Forestry Gene Bank at Kostrzyca in western Poland. Their task is to collect 58 species from 129 natural sites in the western part of Poland. To date, seeds of 31 species from 56 populations have been collected, tested and stored in liquid nitrogen.

In the years 2000-2011, observations were made of shrubs of the cultivars derived from the Rugosa (<i>R. rugosa</i> Thunb.) gathered in the Collection of Rose Cultivars of the Polish Academy of Sciences (PAS) Botanical Garden – Center for Biological Diversity Conservation (CBDC) in Powsin, Poland, including 29 cultivars. In the first part, the results are presented for 12 historical cultivars (‘Agnes’, ‘Belle Poitevine’, ‘Blanc Double de Coubert’, ‘F.J. Grootendorst’, ‘Frau Dagmar Hastrup’, ‘Hansa’, ‘Kaiserin des Nordens’, ‘Max Graf’, ‘Moje Hammarberg’, ‘Mrs Anthony Waterer’, ‘Pink Grootendorst’, ‘Rugeaux du Japon’). Every year, damage to shrubs caused by frost was recorded; the date of bud break and the date when leaves developed in springtime were recorded; regeneration of shrubs damaged in winter was observed; the dates of initial, full and final flowering were recorded; the presence of disease symptoms was observed; and notes were made concerning the need to do spring pruning and pruning after flowering. The winter seasons 2002/2003, 2005/2006, 2009/2010, 2010/2011 were unfavourable for roses. In terms of the features in question, the cultivars varied. The cultivars derived from the Rugosa should find a wider application as park roses (‘Agnes’, ‘Belle Poitevine’, ‘F.J. Grootendorst’, ‘Frau Dagmar Hastrup’, ‘Mrs Anthony Waterer’, ‘Pink Grootendorst’, ‘Rugeaux du Japon’) as well as ground cover and soil protection roses (‘Blanc Double de Coubert’, ‘Hansa’, ‘Kaiserin des Nordens’, ‘Max Graf’, ‘Moje Hammarberg’) planted in urban green areas and near historical buildings.
