AB  - Phytoremediation and phytostabilisation of abandon open miming sites is very important process for rehabilitation of land and watercourses to an acceptable standard. Seed germination and seedling establishment in post-mining sites is of great importance for early succession and restoration patterns. Several of early colonizers are tree species, but they could be very important elements of early successions and influence dynamic of early revegetation in disturbed areas. Spontaneous colonization of mining spoils is difficult due to extremely difficult condition such as extremely low or high pH, mineral soil, low water capacity and nutrient deficiency. Besides this, high concentration and solubility of toxic metals in mining areas could be the most limiting factor for plant establishment. We analyzed parameters of seed germination and seedling growth of early successional tree species (two broad leaf and two pine species species against): Ailanthus altissima, Acer negundo, Pinus silvestris, Picea abies in several experimental systems with three different concentration of toxic metals (Pb, Cd, Zn) to assess influence of metal toxicity in early phase of plant development. Lead in applied concentrations (25, 50 and 100 mu M) did not affect significantly the seed germination percentage in Ailanthus altissima and Acer negundo while cadmium in highest concentrations (100 mu M) caused reduction of the germination percentage, germination index and vigor index in both species. Analysis of the parameters of early seedling development indicates the most pronounced toxic effects of cadmium. In Ailanthus altissima Zn treatments caused significant inhibition of shoot growth and repress development of assimilating organs in concentrations of 25, 100 and 250 mu M. In concentration of 25 mu M Zn caused an inhibition of the root growth. The spruce and Scot pine seeds which were developed on substrates with addition of heavy metals solutions showed significant tolerance to presence of all metals, but percentage of germinating seeds depended on the type of metal and its concentration. The seed of P. abies demonstrated higher tolerance to presence of heavy metals in lower concentrations, then seed of Pinus sylvestris and germinated in all variants. In the conditions of highest concentrations, the seeds of both species did not sprout regardless of the type of metal. The P. abies seedlings were very tolerant to the presence of all metals. The highest concentrations of cadmium had a significant influence on the decrease of the number of the seedlings which survived, as well as on the decrease of biomass in comparison to lead. Zinc had the least adverse effect on the growth and survival of seedlings. P. sylvestris seedlings did not exhibit the same tolerance for the presence of heavy metals.

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  - The aim of this paper was to examine how the heavy metals cadmium (Cd) and lead (Pb) influence the germination and early growth of seedlings of the fast-growing tree species Ulmus pumila L. Seeds were germinated and seedlings were hydroponically grown in a solution with Cd-nitrate and Pb-nitrate at concentrations of 20 mu M, 50 mu M and 90 mu M. Our results show that seeds can germinate in the presence of these two heavy metals at all of the applied concentrations with no significant reduction in qualitative (germination capacity, germination energy) or quantitative (germination intensity, mean germination period) germination parameters as compared to the controls. Early seedling development was also possible at higher concentrations of both heavy metals. Cd reduced hypocotyl length, but not significantly the length of radicles. Pb did not influence hypocotyl length and stimulated radicle length significantly (95%). These results could mark a step forward in defining the tolerance of U pumila to the presence of Cd and Pb, and to the the possibility of using this fast-growing tree which is resistant to different abiotic and biotic stresses, for phytoremediation or soil reclamation purposes.

AB  - In European countries, in natural and semi-natural ecosystems, the invasiveness of species Aster lanceolatus is recognized as great problem for biodiversity conservation. 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.

AB  - Understanding the effects of root Fe deficiency on the uptake and translocation of toxic metals can be important for improving the phytoremediation strategies of polluted soils. The present study investigated how Fe nutritional status affects the uptake and root-to-shoot-translocation of Pb in hydroponically grown seedlings of Ailanthus altissima (Mill.) Swingle. The interactions of Fe deficiency and Pb were assessed by measuring the root Fe(III) reductase activity, carboxylic acids concentration in root exudates, root and shoot biomass, and accumulation of Pb and other metals (Fe, Zn, Mn, and Cu) in roots and leaves of Fe-sufficient (+Fe) and Fe-deficient (-Fe) A. altissima plants. The results indicate that Fe deficiency induced 18-fold higher Fe(III) reductase activity in roots compared with +Fe plants, which was followed by increased root exudation of citric acid (28.2 +/- 1.39 in +Fe and 498 +/- 256.4 mu mol g DW-1 2 h(-1) in -Fe plants). Iron deficiency also induces a significant decrease of root and shoot dry weight compared with the control +Fe plants, whereas 2-wk Pb (20 mu M) treatment did not influence root and shoot growth. Iron-sufficient plants accumulated more Pb (56.8 +/- 17.29 mu g g(-1)) in leaves than -Fe plants (21.5 +/- 8.10 mu g g(-1)). Two weeks of exposure to Pb significantly decreased Fe(III) reductase activity and accumulation of Fe, Zn, and Mn in the roots of -Fe plants. It is hypothesized that 2 wk of root exposure to Pb blocks functioning of a specific Fe transport system activated under Fe deficiency.
