Bot. 27 (1): 001-015. \u2013 ISSN 1210-0420.<\/p>\n Abstract<\/em>: For the study were used Vitex agnus-castus <\/em>L., Lagerstroemia indica <\/em>L. the both as deciduous shrubs and Nerium oleander <\/em>L. as evergreen one. Plants were planted in two variants, in the ground kept there over year and in pots in winter time removed under plastic house where temperature ranged 3-6 \u00b0C. The soil characteristics were comparable in both variants. During of 2011-2013s were assessed processes of adaptability, growth phenophases, year increments and content of chosen metabolites in leaves. Growth phenophases moved on almost one month later at variants in the ground. The year increments at plants planted in pots were significantly less than those planted in the ground and achieved 40-75 cm and 85-95 cm high respectively. The deciduous woody plants planted in the ground were flowered each year, produced germinable seeds and no damage by frost at almost -15 \u00b0C. At evergreen Nerium oleander <\/em>all above ground shoots have frozen at -15 \u00b0C in winter time and regenerated fro m root neck and grown over next year. Those a new shoots were survived through next winter at -5 \u00b0C and leaves from plants of both planting variants were sampled for analyses of selected metabolites. Results shows almost balanced content of starch from both growing variants andachieved 4.73% in pots and 4.34% of dry weight in plants growing in the ground. Total leaf sugar content (in pots\/in the ground) achieved 3.72\/7.39%, chlorophyll a = <\/em>0.60\/0.79 mg.g-1, chlorophyll b = <\/em>0.28\/0.56 mg.g-1 and carotenoids represents 0.27\/0.97 mg.g-1 content in the leaves. The content of analysed metabolites in the leaves of assessed Nerium oleander <\/em>was generally higher at plants in the ground compared with plots and statistically significant. Assessed metabolites should be considered as markers of hardiness in studied woody plants. Sarva\u0161ov\u00e1 I., Luk\u00e1\u010dik I., Pittner J. & Lupt\u00e1kov\u00e1 J.

Bot. 27 (1): 017-028. \u2013 ISSN 1210-0420.<\/p>\n Abstract<\/em>: The work deals with the assessment of growth and morphological characteristics of Ulmus<\/em> laevis<\/em> Pall., Ulmus<\/em> glabra<\/em> Huds., and Ulmus<\/em> minor<\/em> Mill. Altogether, 134 indigenous individuals native to various localities of Slovakia were assessed. The results of measuring dendrometric characteristics showed significant differences in height, tree trunk diameter and crown width especially with the tree species Ulmus<\/em> laevis<\/em> Pall. which was assessed in four stands with different environmental conditions (dried out and waterlogged sites with various soil types). The largest individuals growth on sites with high soil moisture and bedrock diluvia with tufaceous material. Their height average was 24.4 m and diameter average d1,3 76.5 cm. In the other tree stand (two dry and one moisture and poor soil) were ranged height average from 13.6m to 24.7 m, diameter average d1,3 from 21.0 cm to 25.3 cm. On the basis of dendrochronological analyses, the four individuals representing each stand were assessed also with regard to their mean radial increment reaching the values of 2.8 \u2013 7.5 mm per year. The age and position of Ulmus<\/em> trees individual influenced their heights, diameters and crown projections. Health of the assessed species was satisfactory, no considerable damage or attacks by quarantine tracheomycosis Ophiostoma<\/em> novo<\/em>–ulmi<\/em> Brasier were found. Pashkevych N. & Burda R. (2017):<\/strong> Distribution of alien species from Poaceae and Asteraceae families in the protected areas of Ukrainian forest-steppe \u2013 Thaiszia \u2013 J. Bot. 27 (1): 029-039. \u2013 ISSN 1210-0420.<\/p>\n Abstract<\/em>: The current paper evaluates the abundance of alien species from Asteraceae and Poaceae families in different types of biotopes. We have discovered species exhibiting eurytopic properties and forming the ecological niches in three or more biotope types and recorded from only two biotope types, including anthropogenic ones. The majority of anthropophytes from Asteraceae family are eurytopes having the potential to move to other biotopes, due to their ecological amplitude and phytocoenotic strategy. Only five species of Poaceae family showed high exploration trend in different habitat types: Setaria<\/em> viridis<\/em> (L.) P.Beauv., Bromus<\/em> tectorum<\/em> L., B<\/em>. arvensis<\/em> L., B. commutatus<\/em> Schrad., Eragrostis minor<\/em> Host, and have the potential to further spread. It was found that in contrast to Asteraceae family, where eurytopic species prevail, the Poaceae family has only a third of eurytopes in its overall species composition. Alien species distribution for the protected areas of the Ukrainian forest-steppe by generic floristic spectrum revealed two times higher taxonomic diversity of Asteraceae family than the Poaceae one. Among Asteraceae there are such best-represented genera as Artemisia<\/em> L., Helianthus<\/em> L., Xanthium<\/em> L. The analysis of taxonomic structure of the model protected areas and the evaluation of their participation in the formation of different habitat types suggest a\u00a0low taxonomic diversity and quite uneven coenotic role of individual anthropophytic taxa. It should be noted that such genera as Phalacroloma<\/em> Cass., Sonchus<\/em> L., Xanthium<\/em>, Bromus<\/em> Scop. and Setaria<\/em> P.Beauv. have a particular importance, having the leading positions both concerning the wide spectrum of species, and concerning exploration of different biotope types. Geographical distribution analysis showed that the biotopes of protected areas of the central forest-steppe are highly explored by the alien members of Asteraceae and Poaceae families and are located in the floodplains of the Dnieper River. The representatives of Asteraceae family are least recorded in the eastern model floras, while Poaceae family are least recorded in eastern and southern model protected areas. Mikol\u00e1\u0161 V.

Bot. 27 (1): 041-047. \u2013 ISSN 1210-0420.<\/p>\n Abstract<\/em>: Rubus tenuimollis<\/em> sp.nov., a new species of Rubus<\/em> section Corylifolii<\/em> is described from eastern Slovakia. The map of distribution and the scan of the species are added. The species is an apomictic one, probably from the ser. Subcanascentes H.E.Weber and it is known from an area ca. 20 km x 46 km (a local species with the tendency to regional distribution in the classification of Weber). The species grows especially (known distribution) in the area of Ko\u0161ice s.l., however, it reaches \u017dakarovce village in Slovensk\u00e9 Rudohorie Mts. and Dargov village in Slansk\u00e9 vrchy Mts. It is a subxerothermous species, growing on forest and bush edges. It is probable that the new species grows also in Hungary. A bit similar species (growing in eastern Slovakia), Rubus fasciculatus<\/em> is different by sterile stems without stipitate glands, by upper surface of blades very densely hairy, by periodical indentation, shorter flower stalks, receptacle with numerous hairs etc. Lo\u017eien\u0117 K. & Vai\u010diulyt\u0117 V. (2017):<\/strong> Ecological characteristics of habitats and occurrence of Thymus<\/em> pulegioides<\/em> (Lamiaceae) in Lithuania \u2013 Thaiszia \u2013 J. Bot. 27 (1): 049-064. \u2013 ISSN 1210-0420.<\/p>\n Abstract<\/em>: Thymus pulegioides<\/em> L. (Lamiaceae) is essential oils bearing, aromatic and medicinal plant of Central Europe, Scandinavia, Baltic States and South East England indigenous flora. The chemical polymorphism of essential oils can subservient to the selection of valuable clones of T. pulegioides as a\u00a0selection donors from spontaneous populations for the cultivation. T. pulegioides<\/em> grow in natural and semi-natural meadows, however, intensive agriculture led to decrease of areas of natural grasslands with habitats of T. pulegioides<\/em>. The objective of study was to evaluate the occurrence of T.<\/em> pulegioides<\/em> in habitats belonged to different plant communities, characterize habitats according to soil chemistry and other ecological factors. The analysis of 131 different natural habitats of T. pulegioides<\/em> showed that the higher total herb cover can influence on decrease of cover-abundance of T. pulegioides<\/em> (r = -0.24, p < 0.05). More than half of habitats of T. pulegioides<\/em> were established in slopes with the different inclinations; the exposition of majority slopes was southern, southeast and southwest. T. pulegioides<\/em> is indifferent to the soil reaction and does not require a rich soil. Investigated T. pulegioides<\/em> habitats were established in the plant communities of four phytocoenological vegetation classes: Molinio-Arrhenatheretea elatioris<\/em>, <\/em>Festuco-Brometea erecti<\/em>, <\/em>Trifolio-Geranietea sanguinei<\/em> and Koelerio-Corynephoretea<\/em> canescentis<\/em>. More than half investigated T. pulegioides habitats belonged to the grassland communities of vegetation class Molinio-Arrhenatheretea elatioris<\/em>. The significant positive correlation was established between the cover-abundance of T. pulegioides<\/em> and vegetation classes (r = 0.33, p < 0.05): the sequence of frequencies of cover-abundance of T. pulegioides<\/em> +>1>2>3 in habitats corresponds to the following vegetation classes Molinio-Arrhenatheretea elatioris<\/em> > Trifolio- Geranietea sanguinei<\/em> > Festuco-Brometea erecti<\/em> > Koelerio- Corynephoretea canescentis<\/em>, i. e. the higher probable of low coverabundances of T. pulegioides<\/em> is possible in the habitats belonged to the vegetation class Molinio-Arrhenatheretea elatioris<\/em> than in the habitats belonged to the vegetation class Festuco-Brometea erecti<\/em>.

Bot. 27 (2): 65-72. \u2013 ISSN 1210-0420.<\/p>\n Abstract: The article presents the results of study on Biloozersky National Nature Park\u2019s forest vegetation, which occupies 92.4 % of the Park\u2019s territory. The classification of the forest vegetation is made based on the dominant system. The forest vegetation is represented by the communities of the formations Pineta sylvestris, Querceta roboris, Alneta glutinosae, Betuleta pendulae, and Populeta tremulae<\/em>. The area is dominated by pine forests (about 70 %); there are significantly less oak-pine and oak forests. The pine forests with green mosses are the most common. In similar environmental conditions, but on more fertile soils the association Pinetum (sylvestris) convallariosum (majalis)<\/em> occurs often. The communities of the association Quercet\u043e (roboris)\u2013Pineta sylvestris<\/em>, occupy significant areas; they are formed on the straightened plots and the bottoms of slopes. The communities of the formation Quercet\u0430 roboris<\/em> occupy small territories and are confined to the second sandy terrace of the Dnieper. In oak forests the fragments of vernal ephemeroid synusiae occur with Scilla bifolia, Corydalis solida<\/em>, and the rare for the region boreal species Pyrola minor<\/em> and Chimaphila umbellata<\/em>. The derivate communities of Populeta tremulae have been formed on the old pine clearings. The communities of this formation occur on small areas sporadically throughout the Park. The waterlogged ecotopes in the floodplains of the Bile Lake have small areas of Alneta glutinosae<\/em>. Hrivn\u00e1k R. & Slez\u00e1k M.

Abstract:<\/em> Two plant communities, Eleochareto acicularis- Schoenoplectetum supini<\/em> and Elatinetum alsinastrum<\/em> were recorded in the temporary field pools in the Ipe\u013e River inundation area (south-central part of Slovakia). Sandy soils with neutral to slightly alkaline reaction and low values of conductivity were typical for moderately closed, low and species poor to moderately rich stands with the dominance of Schoenoplectus supinus<\/em>. On the contrary, species poor and open stands with Elatine alsinastrum<\/em> dominance grew in shallow alkaline water with high conductivity. This community is documented in Slovakia for the first time.

Abstract:<\/em> Ceratocephala<\/em> Moench (Ranunculaceae, Ranunculeae) is a weedy and medicinal plant with 4-12 accepted taxa in the world from which two are present in Iran: C. falcata, C. testiculata<\/em>. These are wide spread weedy plants in Iran. These two species are sympatric. C. falcata<\/em> is very polymorphic. There is confusion between dwarf specimens of C. falcata<\/em> with C. testiculata<\/em>. In present study, the morphological (macro- and micro-) and anatomical properties of Ceratocephala<\/em> species of Iran have been studied. Totally 27 populations are collected from different localities of Iran. Qualitative and quantitative morphological and anatomical features were evaluated and measured and were used to compare species. Stem and leaf cross sections were considered. Pollen and fruit surface were studied by Scanning Electron Microscopy. Although both species are very similar but the main differences are observed in their fruit surface indumentums and pollen exine sculpture. Species differences are discussed.

Abstract:<\/em> The distribution of Achillea ptarmica<\/em> in Slovakia was studied using herbarium specimens deposited in 22 public herbaria. The herbarium studies were supplemented with targeted field search. The species has been recorded in 28 phytogeographical districts and subdistricts but most of the records are concentrated in the Z\u00e1horsk\u00e1 n\u00ed\u017eina lowland in western Slovakia, in the Slovensk\u00e9 stredohorie Mts. in central Slovakia and in the Slovensk\u00e9 rudohorie Mts. in eastern Slovakia. While most of the occurrences once recorded in the Pannonian part of the country vanished, many new populations were recently found in the Carpathians. Our results show that the evaluation of the species as near threatened (NT) in the recent version of the Slovak Red List is correct.

Abstract:<\/em> Historical and current occurrence of perennial grass Melica altissima<\/em> was studied in Slovakia during 2011\u20132017. The species occurrence was scarce in five phytogeographical districts studied (the Podunajsk\u00e1 n\u00ed\u017eina, Ipe\u013esko-rimavsk\u00e1 br\u00e1zda region, Mal\u00e9 Karpaty Mts., Pova\u017esk\u00fd Inovec Mts., Spi\u0161sk\u00e1 kotlina Basin); we recorded 11 native localities in total, including historical and current sites, as well. The number of localities decreased markedly and we documented only two sites during our field research. Therefore, Melica altissima<\/em> belongs to the critically endangered plants of Slovak flora. Ecological and phytosociological data of M. altissima<\/em> habitats are also presented.

Abstract:<\/em> North of the town \u0160t\u00farovo near Diva settlement a\u00a0rare halophyte, Triglochin maritima<\/em> was found. It grows in stands of the association Puccinellietum limosae<\/em> which occupies the lowest-lying shallow depressions. The site is intensively grazed by cattle, semiruderalized stands of the alliance Potentillion anserinae<\/em> prevail. Although the area is known as an interesting site of inland salt marsh vegetation, the species was not confirmed more than 40 years in the entire Podunajsk\u00e1 n\u00ed\u017eina Lowland. While in the inner basins of the Western Carpathians it has several recent localities in fen vegetation (Caricion davallianae<\/em>), in the Slovak part of the Pannonian bioregion it is the single locality.
