AB  - Today, as always throughout the history of nature, it is an inexhaustible source of inspiration. One of the main goals of creating new biophilic/biomimetic forms inspired by natural structures and patterns is to create a positive psychological impact on people (especially in urban areas) by using geometrical methods and the graphical representation of the plants should convey the symbolism of life. With the progress of civilization and the development of digital technologies, significant biodesign is growing rapidly and becoming necessary in the humanization of today's sustainable way of life. This paper deals with leaf of dandelion (Leontodon taraxacum L.) as bio-inspiration to gain land-art installation as result by using digital modelling throughout Blender, SketchUp and Lumion software tools.

AB  - The structure and function of many forest ecosystems will be modified as a result of air pollution and climate change. Norway spruce (Picea abies L.) forests are among the first terrestrial ecosystems to respond to this change. We analysed how changes in climate and environmental factors will affect vegetation cover in Norway spruce forests and whether it is possible to assemble a list of diagnostically important/sensitive species that would be the first to react to changes in habitats of Norway spruce in Central Balkan. Significant changes in the vegetation cover of Norway spruce forests are mainly influenced by temperature increases (approximate to 4 degrees C), and precipitation decreases (approximate to 102 mm) by the end of the 21st century. Projections show that vegetation cover changes and future habitat conditions for Norway spruce forests on podzolic brown soils with a low base saturation and soil pH decreases, and temperature growth and precipitation decline, with the worst in the Rodope montane forest ecoregion. In Dinaric Mountain and Balkan mixed forest ecoregions, the range of natural occurrence of Norway spruce forest will shift to higher altitudes, or to the north. One of the cognitions of this paper is that, through available environmental models and their indices, species from the IUCN Red List should be recognised more properly and included in model calculations.

AB  - Invasive species Symphyotrichum lanceolatum (Willd.) G. L. Nesom is spreading uncontrollably along wet habitats as well as in disturbed ecosystems. All those habitats function as corridors that facilitate seed dispersal. One way to prevent the spread of invasive species is to know their reproductive ecology. The present study evaluates the potential for generative reproduction of S. lanceolatum and determines how different temperatures, amounts of nutrients, and light regimes, affect seed germination. Seeds collected from 13 natural populations were germinated at four fluctuating temperature regimes (15/6, 20/10, 30/15, and 35/20 degrees C). To test the influence of nitrate on seed germination, two KNO3 concentrations were used (5 mM and 50 mM solution). For each treatment, three replicates of 30 seeds were placed in complete darkness or a 14 h photoperiod. The results showed that the germination increased with increasing temperature. The optimal temperature regimes were 30/15 degrees C and 35/20 degrees C with approximately 88% germination. The overall effect of KNO3 on germination was positive. The concentration of 50 mM KNO3 had a less stimulating effect compared to 5 mM KNO3. Seeds showed sensitivity to lack of light during germination but were able to germinate in a significant percentage in such conditions. Considering that S. lanceolatum often occurs in disturbed sites, these results suggest that seed reaction to alternating temperature, nutrients concentration, and light can be determining factors that affect seed germination of this species and, thus, its spread.

AB  - A growing body of evidence suggests that invasive plants can affect the
   stability of the ecosystem’s key species and influence flows and
   transformations of matter and energy in ecosystems. Since Symphyotrichum
   lanceolatum complex is one of the highly invasive plants in Serbia and many
   European countries, this study set out to determine floristic richness,
   struc­ture, and differentiations among the wet sites near linear corridors
   and to investigate the significance and representation of S. lanceolatum in
   degraded wet habitats. Accordingly, floristic diversity and the presence of
   other invasive plants were investigated in 22 wetland habitats. Overall, a
   total number of 179 plant taxa was found. Results showed four coenological
   groups. According to the invasive species coverage index (D%), S.lanceolatum
   dominated in all stands. Overall, based on the results, this study
   strengthens the idea that wet habitats belong to the group of habitats that
   are most susceptible to plant invasion.

Planina Tara predstavlja prirodno bogatsvo zapadne Srbije gde površine pod serpentinitima zauzimaju 28%. Istraživači se slažu da je flora serpentinskih područja jedinstvena i botanički veoma važna.

AB  - Ultramafic (serpenites) are a group of igneous or metamorphic rocks, which are characterized by high concentrations of Mg, Fe, Ni, Cr, and Co, along with low concentrations of Ca, P, and K, contain less than 45% silicon (SiO2). Tara Mountain is natural good of western Serbia where areas under serpentinites occupy 28%. Researchers agree that the flora of serpentine areas is unique and botanically very important. The specificity of the flora and the development of vegetation on serpentinites are characterized by special mechanisms of plant species adaptation to increased concentrations of some heavy metals in the soil with low content of essential elements (nutrients). This paper examines the influence of serpentinite geological substrate on the occurrence of certain plant species in the initial stages of plant community development. The soil was mainly sampled in rock crevices in the early phases of soil development (Lithosols) where the influence and origin of the metals from the rock can be considered the most obvious. Content of cadmium (Cd) and lead (Pb) in geological substratum, soil and plants biomass is analysed in order to differentiate levels and extents of natural and anthropogenic pollution and also deposition data from the EMEP program (European Monitoring and Evaluation Programme). Results show that the content of lead and cadmium in the soil and plant samples are higher than the content in the corresponding rock sample, except for two soil samples, in which the content of Cd is lower. Thissuggest that the origin of the increased Pb and Cd content might be from anthropogenic sources. Deposition (data from EMEP program) of Cd and Pb, which was analysed for the period from 1990-2018, indicate significant cumulative effect. The values of cumulative deposition in research area have a value of 91,51 kg/km2 lead, while the value of cadmium is 1665 g/km2 , which classifies NP Tara in above-average polluted area in R.

AB  - The paper presents the floristic diversity of the left bank of the Danube and the canal network of Krnjača and Borča settlements, as well as the factors that endanger it. 216 autochthonous and allochthonous plant species were recorded in the investigated area. A large number of invasive plant species have been observed that spread rapidly and easily forming stable populations that displace native plants. Some of them are: Amorpha fruticosa L., Robinia pseudoacacia L., Ailanthus altissima (Mill.) Swingle, Asclepias syriaca L., Ambrosia artemisiifolia L. and others. The presence of 6 species that are rare and endangered in Serbia is especially significant, as well as 5 relict species. During the investigation, the factors which influence on natural habitats degradation and the reduction of autochthonous floristic diversity were identified. Accordingly, measures for protection and preservation of autochthonous floristic diversity are recommended.

AB  - Morpho-anatomical characteristics of Vaccinium myrtillus, V. uliginosum and V. vitis-idaea leaves from several sites of the Central Balkans were examined. The aim of this study was to investigate for the first time morpho-anatomical leaf traits of these species in the studied populations and to identify traits that follow a specific trend along the gradients of climate factors. Leaf traits that discriminate Vaccinium species were as follows: depth of the adaxial cuticule (AdC), thickness of the palisade tissue (PT), thickness of the spongy tissue (ST), height of the abaxial epidermal cells (AbE), height of the abaxial cuticule (AbC) and leaf thickness (LT). Populations of V. myrtillus were characterized by the smallest, and populations of V. vitis-idaea by the highest values for AdC, PT, ST, AbE and LT. Additionally, AbC was significantly larger for V. uliginosum in comparison to two other species. On the basis of morpho-anatomical traits, intraspecific variability of the studied species was explored by Principal Component Analysis (PCA), Cluster Analysis (CA) and Analysis of Variance (ANOVA). CA based on 10 morpho-anatomical traits showed that populations of V. myrtillus and V. uliginosum that grew at lower altitudes (characterized by higher mean annual temperature) are more similar to each other. Especially V. myrtillus was responsive to the elevational gradient and exhibited the highest plasticity in morpho-anatomical leaf traits. Populations of V. vitis-idaea had a different pattern of differentiation along the elevational gradient. CA showed that the populations at the lowest and at the highest altitudes were more similar according to the morpho-anatomical leaf traits, meaning that evergreen leaves were more resistant to environmental conditions.

AB  - This study set out to explore the influence of reduced N concentration and competition on vegetative growth and resource allocation of Symphyotrichum lanceolatum (Willd.) G. L. Nesom and Achillea millefolium L. Comparison of two different genera from the family Compositae will allow the assessment of the impact of morphological or physiological constraints on resource allocation in species occupying the same habitat. Plants were grown in hydroculture. Culture types included two monoculture (invasive S. lanceolatum and native A. millefolium) and mixed culture (combination of those two species). Basic morphological and growth parameters from different treatments (reduced N concentration and control) were detel mined. Dry aboveground and below -ground biomass were measured, as well as the N concentration in leaves and P and K concentration in the above -ground and below ground biomass. The results showed that S. lanceolatum and A. millefolium produce approximately equal above -ground biomass, while S. lanceolatum produces significantly higher below -ground biomass. Further, the study suggests that S. lanceolatum tolerates a lower nitrogen concentration and that it out competes A. millefolium. This S. lanceolatum growth strategy could contribute to its spread since it allocates biomass to below -ground biomass at the beginning of its ontogenetic development, and thus creates the potential for greater resource acquisition.

AB  - The floristic diversity of Deliblato sands SNR is significantly endangered by the spread of invasive plants. In addition to field research, which included the collection of plant material in the area of Deliblato sands SNR, primary and secondary data was collected in this paper. The primary data for the purposes of this study was obtained by applying a questionnaire technique to the management of the protected area - PE "Vojvodinašume" and an expert interview technique to a representative of the Provincial Institute for Nature Conservation. The secondary data was collected to gain a better and broader understanding of the management of Deliblato sands SNR. Based on the field investigations, the analysis of primary and secondary data on invasive plant species was also recognized as a key threatening factor. An analysis of the floristic structure and composition of these plant species, their origin, as well as the manner of their propagation and reproduction was carried out, in order to make a recommendation on the preventive measures for the protection and suppression of invasive plant species and to improve the habitat. In the area of Deliblato sands SNR, 39 invasive plant species (4,33% of the total flora) were found with different invasiveness categories, among which herbaceous, annual, North American species from the Compositae family prevail. Protection measures include the mapping of habitats of invasive species, establishing cooperation with managers and scientific institutions, constant monitoring of endangered habitats and plant species, as well as the creation of a special sector responsible for enhancing biodiversity.

AB  - To address the issues of taxonomic delimitation and to select the material with desirable traits for horticultural use, a comprehensive study of the total variability of morphological characters of two naturally occurring snowdrop species (Galanthus nivalis L. and Galanthus elwesii Hook.) in the central part of the Balkan Peninsula was conducted. The analyses were performed for 16 quantitative characters of aboveground parts of 630 plants collected at 21 geographical points in the territory of the Republic of Serbia. To identify the trends in morphological differentiation, descriptive, univariate and multivariate statistical procedures were employed. Most of the examined characters exhibited moderate degrees of variability (CV from 10% to 20%) and the values of several characters exceeded the limits of variation stated in literature. Samples were mostly morphometrically homogeneous, with comparatively high similarity; only four populations of G. nivalis from the southern and southeastern part of the country were discrete. It is questionable whether these populations merit formal taxonomic recognition at any infraspecific level, but given their decorative qualities, the selected plants can be introduced into cultivation as horticultural plants.

It is questionable whether these populations merit formal taxonomic recognition at any infraspecific level, but given their decorative qualities, the selected plants can be introduced into cultivation as horticultural plants.",

AB  - In this paper the analysis of plant indicator values, several environmental variables and climate change within invaded ecosystems are presented. The aim of the paper was to investigate how climate change will affect floristic structure and distribution. Plant indicator values were determined according to Kojic et al. (1997). Canonical Correspondence Analysis was performed for Asteretum lanceolati community at 13 different sites in broader Belgrade area (Serbia) using Past 3.12 software (Hammer et al. 2001). For analyzing the effects of climate change IPCC's SRES scenarios were used (Nakicenovic and Swart 2000). Coupled Regional Climate Model, EBU-POM (Djurdjevic and Rajkovic 2008) is used for the climate simulations. The strongest gradients influencing communities at these sites are moisture and soil nutrients. The communities are mesophylic, mesothermic to thermophylic, and soils have mostly basic pH reaction, which is characteristic for alluvial habitats, and preferred by named community. The communities prefer such habitats. Communities have the ability to adapt to a great range of environmental condition. According to climate change analysis, long periods of decreased amounts of precipitation, and high temperatures will not be suitable for vast majority of species, especially ones with high demands on water supply, such as: Alisma plantago-aquatica L., Galium palustre L., Oenanthe aquatic (L.) Poir., Rorippa amphibia (L.) Besser, Veronica anagallis-aquatica L., Carex lasiocarpa Ehrh., etc. Also, high temperatures and high amounts of precipitation will be significant for the already prolonged flowering period, and the life cycle of many invasive plants. It is found that many plants in the studied communities are alarming examples, because they are allelopathic clonal plants which can strongly cause the displacement of native plants.

AB  - The content of microelements in the soil and their accessibility to the plants, depends on various abiotic and biotic factors, but also on certain characteristics of plant species. A high level of translocation and bioaccumulation of some microelements can result from specific forms of metal-organic complexes that are easily transported as well as certain soluble compounds due to organic matter decomposition. The aim of this paper was to determine the degree of uptake, transport and accumulation of Pb and Cd in natural conditions in common bent (Agrostietum capillaris Z. Pavlović 1955) community. Study area were meadow community on the Mt. Stara planina (locality Javor) and Mt. Zlatar (locality Vodena poljana). Soil samples were taken at fixed depths, and physicochemical properties were determined, while parts of aboveground and belowground biomass were taken according to the IPCC methodology. The translocation and bioaccumulation were measured based on factors given by shoot to root ratio of Cd and Pb concentrations in soil, belowground and aboveground biomass. The concentrations of Pb and Cd in the studied soils at both locations are lower than the limit values, but the average Pb content is higher in the area of Zlatar Mt. which is statistically significant. There is a strong correlation between Pb and soil properties on Zlatar Mt, while Cd shows statistically significant relation to soil properties on Stara planina Mt. Pb concentration are higher in belowground biomass compared to the aboveground, with significantly higher concentration on Zlatar Mt. The translocation factor shows that Pb is accumulated in higher content in belowground biomass compared to aboveground, both onland Zlatar Mt, but low values of this factor show that there is no translocation process from root to aboveground biomass. Foliar uptake is also known as the source of toxic microelements, from wet deposition. Although Pb is a metal which is mainly accumulated in the roots, its higher concentrations in the belowground biomass on Zlatar Mt. may be the result of available Pb forms originating from a cross-border deposition. Pb concentration in aboveground biomass is within the limits of natural concentrations both on Stara planina and Zlatar. Cd concentrations are higher in belowground biomass at both sites, compared to aboveground biomass, as indicated by translocation factor, with values  lt 1. The ratio between belowground biomass and soil shows that TF values are significantly gt 1 both on Stara planina and Zlatar Mt., which indicates a high level of Cd uptake by plants and its transport to aboveground biomass. However, foliar uptake is also characteristic for Cd, whereby this element is easily transported to the other parts of plants through various forms of metal-organic compounds, and accumulated in the root. As a proof of that process, the values of bioaccumulation factor are significantly higher than 1 at all profiles except one on Zlatar Mt. which is also confirmed by the strong correlation between the content of Cd in the belowground and aboveground biomass.

AB  - Intense direct and indirect human pressure has been imposed on grasslands throughout their range. Mostly due to the constant need for more food production or due to changes in environmental conditions, grasslands as habitats are expected to become highly endangered. The aim of this study was to estimate the grasslands' ecological response to future climate and environmental changes. The study took place in three ecologically different grassland communities in three protected natural areas of Serbia (Southeastern Europe), following the same methodology. The study sites were: 1) Pestersko polje Special Nature Reserve (SNR), 2) Deliblato sands SNR (its southern part: Labudovo okno) and 3) Zasavica SNR. Climate change was simulated for mean temperatures and precipitations using the Eta Belgrade University-Princeton Ocean Model (EBU-POM) climate model, for the A1B Intergovernmental Panel on Climate Change (IPCC) emission scenario covering the 1951-2100 period and insolation and volumetric soil moisture content for the 1979-2100 period. Grassland vegetation was analysed at all three sites. One representative plant community per site was selected for further analysis and simulation of ecological changes. One plot was positioned inside each of the above-mentioned communities, all vascular plant species inside the plot were recorded, and soil samples were taken. Ecological Optima (EO) for moisture and temperature were calculated from modified Ellenberg's plant indicator values of recorded species. The plants' response to climate and environmental changes was simulated using the VSD+ model for the 2010-2100 period. The data obtained from the model were further analysed with Canonical Correspondence Analysis (CCA). Overall results show that the temperature rise, along with the irregular precipitation at all three sites, will lead to a drop of the relative abundance of many native species in the period between 2040 and 2060. The low obtained Habitat Suitability Index for the future means that there will be either unfavourable environmental conditions for the development of grasslands, or the species we analysed were untypical. Cosmopolitans and xerothermic species will be more accustomed to the new conditions. Grasses will be the most resilient functional group according to our study. It may be concluded that the functional group of grasses will also play the leading role in future grasslands at the studied sites.

AB  - Invasive plants are one of the major treat to local communities and ecosystems in urban habitats. Aster lanceolatus Wild. is one of the most spreading invasive plant species in Serbia and to examine its impact on soil, flora and aboveground biomass in urban habitats we investigated the pH, electrical conductivity and concentration of trace elements (Zn, Cu, Ni, Mn) in four invaded and four uninvaded plots in urban habitats. We also studied floristic composition and floristic richness regarding these invasive plant populations. These parameters were assessed along transects arranged in the cross shape, running from the centre of the invaded area towards the peripheral uninvaded area. Trace elements were analysed using atomic absorption spectrophotometer. Statistical differences were analysed using ANOVA and post-hoc LSD-tests. The results showed an important decrease of the number of species and herbaceous cover under A. lanceolatus populations. There were no statistically significant differences between invaded and uninvaded patches when soil pH and electrical conductivity were considered. The concentration of Zn, Mn and Ni in the soil was higher in invaded areas. The content of Zn in aboveground biomass collected from invaded compare to uninvaded areas was higher. This study raises the possibility that invasive species changes soil characteristics and create conditions for their spreading.

AB  - Background and Purpose: Aster lanceolatus Willd. is a highly invasive plant in Serbia. However, mechanisms that allow A. lanceolatus to be so competitive and to become dominant in riverine plant communities are not clear. Several potentially allelopathic compounds have been identified in A. lanceolatus tissues and those substances could possibly contribute to the rapid spread of this species. Materials and Methods: In this paper, the allelopathic potential of Aster lanceolatus Willd. was studied. Lactuca sativa L. and Sinapis alba L. were selected as the bioassay species. Under laboratory conditions, different concentrations of aqueous extracts of A. lanceolatus were applied to determine their effect on seed germination and seedling growth of the test species. Influences of various aqueous extracts on the germination of bioassay species were tested using one-way analysis of variance (ANOVA). In addition, radicle and hypocotyl lengths and dry weight of seedlings were expressed as a percentage of growth inhibition of the control. Results and Conclusion: The bioassay present in this paper has shown that the aqueous extracts obtained from different vegetative organs of A. lanceolatus have an inhibitory effect on seed germination and seedling growth of the test species and that those potentially allelopathic compounds could contribute to the competitive ability of A. lanceolatus against native plants.

AB  - Mt. Kopaonik is distinguished by a high level of biodiversity. In 1981 Kopaonik is promoted into the National park within former Social Federal Republic of Yugoslavia. Part of the National park is known as the oldest and the biggest ski resort in Serbia. The aim of this study was to determine key environmental factors influencing a floristic composition of a surveyed ski trails. The data set included 58 phytosociological releves recorded between 2010 and 2013. A total of 322 plant species was recorded in the analyzed ski areas of the Mt. Kopaonik taxonomically belong to 42 families and 136 genera. The main environmental gradients of species composition were analyzed by Detrended Correspondence Analysis (DCA). Ecological indicator values were used for ecological interpretation of ordination axes. The results of the DCA indicate that the main environmental gradient in the plant species composition of the ski trails was related to the moisture and nutrients. This is due to construction and the maintenance of ski slopes. The represented study gives useful information for the future maintenance of the ski slopes (primarily mowing, grazing, fertilize and overseeding) and selecting species for seed mixtures for restoration of ski slopes.

AB  - Parkway trees in urban environments have a pivotal ecological role, primarily because they modify microclimatological parameters. Norway maple is a suitable species for these purposes since it is very adaptable to city conditions. This characteristic of Norway maple allows urban trees to be used as a basis for biodiversity conservation. Bilaterally symmetrical fruits of Norway maple are particularly convenient for the exploration of developmental stability and the role of genetic and environment in variability of morphological characteristics of Norway maple. Variability change through different conditions could be used for creation of a scale that could serve to predict morphology of Norway maple in different environments. The differences between fruits collected from 4 locations show great variability of the species, but the size and appearance of the fruits are in accordance with literature data and do not deviate in any group of samples. Despite similar normal distributions of groups, the fruits differ significantly, although these variations are not consequences of a cause-and-effect connection between environment and appearance of fruits. Variability of samples taken from the urban environment does not differ from variability of samples taken from natural habitats. The large variability of Norway maple is expected since it has a wide ecological amplitude as well as a small plasticity, which is typical of species adapted to shadowy conditions. The great variability of fruit morphology within each individual is typical of Norway maple, so these could be used as representatives of the population in which they are grown. In this paper it is shown that the differences found between fruits are the result of genetic variations mosaic; that is, they are different ecotypes of Norway maple, since bilaterally symmetrical fruits do not have significantly different left and right sides, which shows the developmental stability of Norway maple.

AB  - The aim of this study was to determine the possibility of micropropagation of the medicinal plant A. millefolium on half-strength MS medium and ex vitro rooting and acclimatization of the obtained microshoots in hydroculture in order to establish an efficient production method. Two explant types were used: basal and terminal cuttings, and better results were achieved when terminal cuttings were used. The development of shoots in the multiplication phase was successful with a regeneration percentage of 100%. Ex vitro rooting in a modified Hoagland nutrient solution was successful (83%), but the percentage of in vitro rooting on half-strength MS medium without hormones was higher (95%). However, bearing in mind that mass production of A. millefolium is more efficient when the phase of in vitro rooting is excluded, this method could be recommended for commercial propagation of this medicinal plant. It is necessary to conduct additional research in order to optimize the composition, EC and pH value of the hydroponic nutrient solution.

AB  - Vaccinium myrtillus L., Vaccinium uliginosum L. and Vaccinium vitis-idaea L. are perennial, cold-adapted clonal shrubs distributed throughout Europe, northern Asia and North America. Due to their usage in food (berries) and pharmaceutical industry (berries and leaves), their natural populations are exposed to anthropogenic and other impacts that affect their genetic make-up. We analyzed 14 fragmentary distributed and small-sized peripheral populations of these species from the Balkans, which represents the southeastern-European marginal area of their wide European distributions, using RAPD molecular markers. The contemporary genetic patterns in all three species within the Balkans were generally similar, and in comparison to previous reports on populations of these species found in northward Europe, where they have a more continuous distribution, the levels of genetic diversity were more or less halved, genetic differentiation was several times higher, gene flow exceptionally low, and the expected prevalence of clonal individuals was lacking. The population dynamics of all three species within the Balkans was complex and distinct, and was characterized by a past admixture of individuals from discrete populations of the same species and interspecific hybridisation not only between V. myrtillus and V. vitis-idaea but also between V. uliginosum and V. vitis-idaea, the latter not being reported to date. Conservation measures suitable for preservation of presumably genetically distinct portions of the Balkans' gene pools of studied species have been suggested, while the utility of interspecific hybrids in breeding programs and/or in food/pharmaceutical industry is yet to be assessed.

AB  - U radu je istraživan uticaj regulatora rastenja na klijanje semena judinog drveta (Cercis siliquastrum L.) koje pokazuje dvostruku dormantnost. Istovremeno je testirano seme pripremljeno na uobičajeni način: skarifikacija + stratifikacija i skarifikovano seme tretirano regulatorima rastenja iz grupe giberelina, auksina i citokinina. Rezultati ukazuju na pozitivne efekte giberelinske kiseline (GA), kao i na neke kombinacije ovog regulatora rastenja sa drugim ispitanim. Preporuke za praksu su kombinacija uobičajene procedure sa GA. Postupak skraćuje vreme stratifikacije tako što se GA aplicira pre stratifikacije jer temperatura od 4°C ne obezbeđuje aktivnost regulatora rastenja. Rezultati mogu da posluže kao osnova za lakše generativno razmnožavanje ove važne dekorativne vrste koja može da nađe širu primenu u promenjenim klimatskim uslovima.
AB  - The study deals with the influence of growth regulators on the germination of Judas tree (Cercis siliquastrum L.) seed which is double dormant. We simultaneously tested seeds prepared in the conventional procedure: scarification + stratification and scarified seeds treated with phytohormones from the groups of gibberellins, auxin and cytokinins. The results indicate a positive effect of gibberellic acid (GA), as well as some combinations of this phytohormone with others. Recommendations for practice are to combine the conventional procedure with GA. The procedure may shorten the duration of stratification; the application of GA should follow stratification because the temperature of 4°C does not provide growth regulators activity. The study results can serve as the base for easier generative reproduction of this valuable woody ornamental species which could have a wide use in changed climate conditions.

Rezultati ukazuju na pozitivne efekte giberelinske kiseline (GA), kao i na neke kombinacije ovog regulatora rastenja sa drugim ispitanim. Preporuke za praksu su kombinacija uobičajene procedure sa GA. Postupak skraćuje vreme stratifikacije tako što se GA aplicira pre stratifikacije jer temperatura od 4°C ne obezbeđuje aktivnost regulatora rastenja. Rezultati mogu da posluže kao osnova za lakše generativno razmnožavanje ove važne dekorativne vrste koja može da nađe širu primenu u promenjenim klimatskim uslovima., The study deals with the influence of growth regulators on the germination of Judas tree (Cercis siliquastrum L.) seed which is double dormant. We simultaneously tested seeds prepared in the conventional procedure: scarification + stratification and scarified seeds treated with phytohormones from the groups of gibberellins, auxin and cytokinins. The results indicate a positive effect of gibberellic acid (GA), as well as some combinations of this phytohormone with others. Recommendations for practice are to combine the conventional procedure with GA. The procedure may shorten the duration of stratification; the application of GA should follow stratification because the temperature of 4°C does not provide growth regulators activity. The study results can serve as the base for easier generative reproduction of this valuable woody ornamental species which could have a wide use in changed climate conditions.",

AB  - This paper presents a study of Zn, Cu and Cd availability to three Vaccinium species (V. myitillus, V. uliginosum, V. vitis-idaea) in the natural field conditions of Stara Planina Mt. (East Serbia). The Vaccinium species are often used for both consumption and production of different pharmaceutical products. It has been found that some species of this genus are tolerant to the high content of trace elements, which makes them highly recommended for many phytoremediation programs. The study was conducted at two localities (Babin Zub and Javor) whose dominant soil type is Dystric Leptosol. At both localities the soil was sampled from soil profiles in eight sites. At each sampling site the soil was sampled at depths of 0-5, 5-10, 10 -20 and 20 - 40 cm, and for each species the plant material studied was collected from a 10x10 m square plot. The air dried soils and plant material were milled and digested with aqua regia. The aqua regia-extractable content of trace elements was measured. The content of trace elements extractable with the DTPA chelat agent is defined as mobilisable metals. The contents of trace elements (Cd, Cu and Zn) in the extracts were determined by AAS. The contents of aqua regia-extractable trace elements in the studied soil were lower than the limit values for multifunctional use. The highest concentrations of Cd and Zn were measured in V. uliginosum, and of Cu in V. myrtillus. The correlation found between the content of trace elements in plants and trace elements in the soil is important for a better understanding of their interactions, as well as for the intensive use of Vaccinium species in food production in the investigated region of Serbia.

AB  - Aster lanceolatus Willd. is a herbaceous perennial that is considered invasive in many European countries. In Serbia, this plant inhabits wet habitats and forms widespread monospecific stands. The objective of this research is to determine whether generative reproduction has an important role in the expansion of this species to new areas. In 13 different localities, fruit heads were collected from lateral and terminal parts of infructescence. Seed quantity and germination parameters were determined for seeds in the fruit heads. The results showed that the position of the fruit heads did not have a major impact on germination parameters. However, germination parameters differed among the localities. The findings of this study suggest that A. lanceolatus produces a great amount of viable seeds that germinate in an amount sufficient to ensure a successful spread of this invasive species to new areas.

AB  - An important activity in environmental protection is the possibility to grow woody plants in soils contaminated by toxic metals for phytoremediation, or biomass production in order to obtain energy. The aim of this paper was to find out the effects of the heavy metals cadmium (Cd) and lead (Pb) on germination and early seedlings growth of tree species Ailanthus altissima (Mill.) Swingle and Acer negundo L. Seeds were germinated in 0, 20, 50 and 90 mu M concentrations, in the form of lead nitrate and cadmium nitrate. Results show that seeds of both species can germinate in the presence of both heavy metals. Germination capacity of seeds treated with highest concentrations of Cd and Pb nitrate was higher for A. altissima (88.66 and 94.67%, respectively). Seedlings development of both species was possible in terms of stronger concentrations of both heavy metals, so these species can be considered to be tolerant to presence of Cd and Pb, and need further investigation. A. altissima seedlings had 4-7 fold higher biomass production and higher tolerance to Cd and Pb treatment. Results can be a contributing step in investigating and defining the tolerance limit of these woody species at different levels of Cd and Pb.

In order to detect the basic floristic differentiation at the level of analyzed habitats and associations, ordinary CA was applied. Hierarchical cluster analysis (UPMGA) and non-metric multi-dimensional scaling (nMDS) were used for exploring the floristic relationships among researched. habitats and communities. SIMPER analysis determined percentage of average dissimilarity of species pool of compeering associations. DCA analysis was conducted with the aim of length gradient determination as a base for selection of unimodal ordination. Ordinary CCA was used in order to detect distribution site score of investigated sites related to the explanatory variables, and to establish their impact on ordination score results. Comparative analysis of floristic composition has shown differentiation into five habitat groups. The more detailed level of the corresponding analysis at association level shows homogenization of associations where Aster lanceolatus is an edificatory species, separating them from the others where it is a koinobiont. The variability of habitats was caused by variation in two negatively correlated environmental factors: pH of soil and altitude. The other environmental factors have shown a significantly smaller influence on variability of final score.
