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.

In the second part, the results are presented for 17 modern cultivars (‘Bokratrack’, ‘Dart’s Defender’, ‘Handwar’, ‘Hanpur’, ‘Hansno’, ‘Hanuhl’, ‘Korgosa’, ‘Korhassi’, ‘Korruge’, ‘Magsed’, ‘Rokoko’, ‘Speruge’, ‘Strolen’, ‘Stronin’, ‘Thérèse Bugnet’, ‘Uhlwe’, ‘White Grootendorst’). 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 observations made confirm the high frost resistance of Rugosa hybrids and their low cultivation requirements, owing to which they deserve a wider application, in accordance with their intended use, both as amateur varieties and for urban green areas.

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.

Systematic studies carried out in the greenhouses of the Botanical Garden - Center for Biological Diversity Conservation of the Polish Academy of Sciences in Warsaw-Powsin revealed that the flora of weeds ras very rich there. A total of 243 taxa of vascular plants and 17 species of bryophytes were recorded. With regard to the division of the flora of vascular plants according to species origin and degree of naturalization, it was found that native plants (89 species), greenhouse-escapes (87 species) and permanently established aliens (48 species) co-dominated there. In addition, 10 species of garden-escapes, i.e. plants cultivated in the immediate neighbourhood of greenhouses, were recorded indoors. Noteworthy were two species that had been brought accidentally to the glasshouses together with plant material - this group of plants is least numerous but quite frequent in the study area. Observations made in the vicinity of Powsin greenhouses showed that relationships between the studied flora and the plants growing outside were unilateral. In Powsin no proved example of expansion of greenhouse plants to other parts of the Garden has been recorded. By contrast, influx of diaspores to the study area is observed frequently - the flora of greenhouse weeds is dominated by plants found also in the immediate neighbourhood (147 species). The most important factors affecting the composition of the weed flora of glasshouses include the flora of the surrounding areas and the mode of greenhouse management (e.g. the range of species cultivated there). The diversity of the flora is not related to greenhouse size.

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.

Abstract This work refers to the native species of genus Astragalus L. (A. dasyanthus, A. ponticus), Adonis L. (A. vernalis, A. wolgensis) and Digitalis L. (D. lanata, D. grandiflora). The plants are cultivated in the Botanical Garden of Moldova in the field collection of the medicinal and aromatic plants. Investigation includes propagation aspects, research into cultivation techniques and conservation measures. The biological particularities and the phenologic rhythm are also registered. The obtained data shows the ecological flexibility of species and the possibility of preserving them in culture.
