This work aimed to underline the dynamics of photosynthetic and oxidative stress parameters of ‘Matador’ and ‘Andromeda’ spinach species after short-term 1 and 2 kJm–2 UV-B radiation effect. When plants reached 3–4 leaves growths stage, the exposure to 1 kJm–2 and 2 kJm–2 UV-B radiation was done once for 68 and 136 minutes, respectively. The photosynthetic and oxidative stress parameters were determined 2, 24, 48 and 72 hours after exposure. The stimulating effect of UV-B emerged on the 3rd day after exposure. The positive effect of UV-B was more pronounced for ‘Matador’. The highest DPPH radical-scavenging capacity and the highest concentration of α-tocopherols were detected 24 hours after 2 kJ UV-B exposure, but the decrease in photosynthetic rate was the highest as well. Meanwhile, on the 3rd day after 1 kJ UV-B exposure, the indicators of oxidative stress of ‘Matador’ decreased, and the photosynthetic rate increased. This study highlights that low UV-B radiation acts as an eustress, by awaking positive changes in photosynthetic and oxidative stress parameters of spinach.

River valleys are areas of transition between aquatic and terrestrial communities, with complex biological structure. As ecotones they have high biodiversity as a result of the occurrence of species with different requirements according to soil moisture. They create ecological corridors, allowing migration of the organisms in human disturbed landscape. With these migration routes, species of foreign origin which spread to a new area also benefit. Numerous alien species are considered as invasive, and described as a threat to biodiversity due to strong competitive abilities. To describe the relationships between a number of invasive species, biodiversity and size of a river, the vegetation of 750 m fragments of the Odra and Dobra river valleys on the area of the Wrocław city were analysed. The comparison of plant communities in the valley of a large, managed river (Odra) and its small tributary (Dobra) was carried out. The plant assemblages, occurring in study areas, determined the habitat conditions on the basis of Ellenberg’s indicator values (EIV’s), as well as Shannon-Wiener biodiversity index was defined. The designed sites differed according to Shannon-Wiener biodiversity index, as well as soil properties: moisture, reaction, and fertility. In the study side of the Odra river ruderal and scrub species were dominated, whereas in case of study site of the Dobra river – meadows and ruderal species. The invasive plant species occurring in the Odra valley are: Symphoricarpos albus, Solidago gigantea, S. canadensis, Robinia pseudoacacia, Clematis vitalba, Quercus rubra, Reynoutria japonica, Parthenocissus inserta and Echinocystis lobata, and in the Dobra valley: Solidago gigantea, S. canadensis. The analysis of correlation between Shannon-Wiener biodiversity index and share of invasive species revealed statistically significant influence of occurrence of invasive species on biodiversity of plant communities in case of the Odra river.

Mostly parks and forest are the most important ‘green islands’ in urban ecological network. Urban forests are belong to green areas and collected many plant species. The main aim of the article was characteristic of ancient plant species in urban forests in Tarnów. The field studies were carried out in years 2011–2012. It covered 80 phytosociological records on the area 500 m2 in herb layer of urban forests and in forest nature on oak-hornbeam. The results showed that many ancient plant species were growing in urban forest but less than in nature reserves.

The paper attempts to synthesize the determinants which may influence the diurnal rhythm of blooming. Additionally, I tried to explore and bring together topics that concern blooming and have always been considered separately because of their origin in different disciplines. The following species were included: Hydrangea arborescens L subsp. discolor (Raf.), H. paniculata Sieb., Viburnum opulus L, Chaenomeles japonica Lindl., Knautia arvensis L., Adonis vernalis L., Aster saggitifolius Willd., Taraxacum officinale L. Chelidonium majus L. The taxons were observed in Lublin (51 08’ – 51 18’ N and 21 27’ – 21 41’ E) in the years 2001-2007. The blooming of species was determined at least for two vegetation seasons. During observations all flowers developed in one-hour intervals were counted. The diurnal dynamics of blooming differs among species and is modified by different endogenous and exogenous factors. The endogenous determinants of diurnal dynamics of blooming are morphological diversity of flowers (fertility or sterility) within species or heterostyly. The different pattern of blooming succour different mechanisms which prevent self-pollination (Chaenomeles japonica Lindl., Knautia arvensis L.). The abiotic factors, such as day length and temperature during the vegetation season, influence the change in the process of diurnal dynamics of blooming (e. g. Taraxacum officinale, Chelidonium majus)

The aim of the study has been to determine the effect of some substances such as dolomite, loam, compost, pinewood bark, peat, lime, charcoal, natural and synthetic zeolite on reducing the impact of soil contamination with arsenic on the content of manganese in some plant species. The content of manganese in the test plants depended on the degree of soil contamination with arsenic, application of different substances as well as on the plant species and organ. Soil contamination with arsenic caused either an increase or a decrease in the content of manganese in plants depending on a plant species and organ. In the series without soil amending substances, in the arsenic contaminated objects the manganese content decreased in above-ground parts of cocksfoot and swede but increased in above-ground parts and roots of maize and yellow lupine, in roots of cocksfoot and swede and in straw and roots of spring barley. On the other hand, the highest rates of arsenic depressed the content of manganese in roots of cocksfoot, swede and spring barley. Addition of any of the aforementioned substances to contaminated soil changed the content of manganese in the plants. The most unambiguous effect of the different substances was determined in the case of above-ground parts of maize as well as above-ground parts and roots of cocksfoot, in which the manganese content fell down, and in roots of yellow lupine, grain and straw of spring barley, in which the content of manganese rose. Charcoal and loam caused the largest and synthetic zeolite led to the smallest changes in the content of manganese in plants.

We provide information about two species, Pilosella bauhinii and P. cymosa subsp. vaillantii (Asteraceae), from new localities in north-central Poland (ATPOL DC18). All individuals of both species grew on a railway embankment in Górzno-Lidzbark Landscape Park. The ecological preferences for P. cymosa and P. bauhinii estimated according to average Ellenberg values nearly coincided with the original description of Ellenberg. We also sequenced the barcode marker, plastid trnH-psbA intergenic spacer, for two individuals of P. bauhinii, three specimens of P. cymosa subsp. vaillantii, and additionally two individuals of P. officinarum L. and one H. murorum L. growing in close proximity. A pairwise comparison of trnH-psbA sequences showed that each species has a unique haplotype. Taking into account their morphological coherence, it is possible that both P. bauhinii and P. cymosa have not hybridized yet, at least locally, with the more abundant species (e.g., P. officinarum). A search for reference sequences did not provide additional information because of the low quality of the reference database for this group in GenBank. Only 14 sequences of trnH-psbA were available with some apparently being misidentified or of low quality. None were identical to sequences of P. cymosa subsp. vaillantii and P. bauhinii found in this study.

Fire usually causes changes in the composition and diversity of herbaceous species. The present paper aimed to study the effect of repeated fire incidents on understory species diversity in the Saravan forests of Guilan Province located in the north of Iran. To do so, three 50-hectare areas with identical physiographical conditions and overstory (hand-planted softwood Pinus taeda) were selected. Seven fire incidences occurred for the 10-year period in one of the areas and the other area experienced three fire incidents within the same period. The area with no fire incidents was considered as the control area. All the fire incidents were surface ones. The systematic random method with a sample size 100 × 200 m was used for collecting data. Based on the above, 25 samples were determined in each area. The whole coverage of the understory was taken into consideration using Whittaker’s method and the Domain criterion so as to calculate species diversity indices. The results showed that Shannon-Wiener diversity and Menhinick’s richness in the regions which experienced 3 and 7 fire incidents were maximum and minimum, respectively, whereas no significant difference was seen between the regions with regard to Smith and Wilson’s evenness index.

P. exigua var. exigua was isolated from underground and aboveground organs of different herb plant species in the years 1998-2006. Pathogenicity tests of three randomly chosen isolates of the fungus T 299, T 261 and T 277 for thyme and of three isolates M 1657, M 1193 and M 1635 for lemon balm were carried out. The effect of water suspension of fungus spores on the germination ability of schizocarps and of infected soil on sprouting and seedling health was studied. The study of microscopic structures of the fungus developing on plants, isolation of the fungus on artifi cial media and macro- and microscopic analysis on standard media are essential for the correct identifi cation of P. exigua var. exigua. The polyphagous nature of the fungus is confi rmed by the obtained results. The tested isolates were found to be occasional pathogens of thyme and lemon balm in the studied conditions. The harmfulness of the tested isolates pointed to inhibition of schizocarp germination, sprouting of plants and the ability to cause necrosis of germs, roots and epicotyl.

Propagation of juniper from cuttings is the primary method used in the nursery. Process of rhizogenesis in these plants is long and not always allows to obtain a good quality of rooted cuttings. In the experiment there was investigated the effect of laser light doses (semiconductor laser, model CTL 1106MX, power 200 mW, wave length 670 μm) and the footing agent AB on percentage of rooted cuttings, plants height, length and the number of roots. The examined juniper taxa proved diverse response to the variants applied (combination of laser radiation and the rooting agent AB). The increase in the number of rooted cuttings after application of the rooting agent AB, as well as three times introduced irradiation in Eastern redcedar ‘Blue Arrow’. This form also produced longer roots for the variant combining twelve times applied irradiation and the effect of rooting agent. In the cuttings of Chinese juniper ‘Stricta’, exposed to laser radiation in six – (D6) and twelve times applied doses (D12), there was observed significant stimulation of root length. Introduced treatment variants of shoot cuttings of Common juniper ‘Schneverdinger Goldmachangel’ brought about considerable root elongation (except for D3 dose). The dose providing for significant increase in the percentage of rooted cuttings in all the examined juniper varieties proved to be D3 dose.
