Celem badań było określenie wpływu zasolenia gleby na wzrost i rozwój wybranych gatunków roślin. Do badań wytypowano dwa gatunki z rodziny traw: kupkówkę pospolitą (Daetylis glomerata L.), życicę wielokwiatową (Lolium multijlorum L.) oraz dwa z rodziny motylkowatych: koniczynę łąkową (Trifolium pratense L.), wykę siewną (Vicia sativa L.). Warunki rozwoju roślin zostały zróżnicowane poprzez wprowadzenie zasolenia na poziomie O, 2, 6, 12 i 20 mS' cm-l w temp. 25°C. Dla większości kombinacji zaobserwowano obniżenie przyrostu biomasy pod wpływem zasolenia gleby u wszystkich badanych roślin. Badania wykazały, że zastosowane trawy są bardziej tolerancyjne na zasolenie niż wybrane motylkowate. Wyniki badań pozwoliły na określenie, iż z roślin należących do rodziny traw nieznacznie bardziej tolerancyjna na zasolenie jest życica wielokwiatowa. Spośród motylkowatych większą tolerancją wykazała się wyka siewna, mniejszą koniczyna łąkowa.

The aim of this research was to determine the effect of soil salinity on growth and advancement of selected plant species. Two species of Poaceae and two species of Fabaceae were chosen to conduct the research. The conditions of plants growth were diversified through introduction of salinity at levels 0, 2, 6, 12 i 20 mS źcm-I. For the majority of combinations of researched plants the reduction of biomass accumulation caused by the soil salinity was observed. The results showed that the Poaceae were more tolerant to soil salinity than Fabaceae. The research results show that Lolium multiflorum L., were more tolerant to soil salinity than Dactylis glomerata L .. Out of Fabaceae Vicia sativa L. showed greater tolerance than Trifolium pretense L..

A preliminary inventory of the vegetation at the proposed site of the botanical garden of Ekiti State University was carried out with a view to providing baseline information about the richness, distribution, economic and medicinal importance of the available plant species. This is to serve as fundamental knowledge for a periodical assessment of impact as the garden is fully established. The proposed site measures 1944 m2 in size. With the aid of a geographical compass, the entire land area was divided into four axes (i.e. north-, south-, east- and west-wards) to serve as guide for enumerating the plant species and assessing their pattern of distribution. Plant collections were made from the four axes by means of secateurs and vasculum and thereafter prepared as herbarium specimens which were stored in the University Herbarium. Forty plant families, comprising eighty-four species were noted for the inventory. The economic and medicinal importance of the plant species was recorded. As at the period of the exercise, five plant species were abundant, twenty-three were occasional, while fifty-six were rare. It was deduced that the site is a secondary forest, rich in plant species and would be less costly to be prepared for the establishment of a botanical garden. Goals of sustainable development and species conservation was set for the management of the said garden.

This paper presents the results of the heavy metals accumulation (Cd, Cr, Pb, Cu, Zn, Mn, and Fe) in soils and plants (Typha angustifolia L., Urtica dioica L., Ranunculus sardous Crantz and Rumex Crispus L.) collected along the banks of the Sitnica River, which flows through various cities of Kosovo and is quite stressed due to the discharges of urban, industrial, and agricultural pollutants. The aim of this research was to verify the accumulation of heavy metals in water, soil and plants, since vegetables that used as food are cultivated in the vicinity of sample collection. The analyses were conducted with applied methodology in the analytic laboratory of Kosovo Agriculture Institute by using MP-AES 4200 for Cd and Cr, ASS-Scientific for Zn, Cu, Fe, Mn and Pb in plant samples, whereas 4100 MP-AES was used for determination of metals in soil. The results show variations in different metal values found in the samples of the analyzed soils and plants. The lowest values accumulation of the metals analyzed were recorded at A1 (Devetak Station) near the river source and did not contain anthropogenic influences, whereas the highest values were recorded at A3 (Kuzmin Station), which belongs to the middle flow of the Sitnica River that is polluted by wastewater (urban) discharges.

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.

A comparative morphological and anatomical study on the petioles and lamina of 22 taxa (species, subspecies and cultivars) of the genus Philodendron (subgenera Meconostigma, Pteromischum and Philodendron) has been made in order to investigate interspecific differences which may be useful in species identification. All species have bifacial leaves with petioles, amphistomatic with a strongly reduced density of stomata on the adaxial leaf surface. The species differ in the size and shape of their epidermal cells, the distribution and types of stomata and cuticle ornamentation in the lamina, thickness of epicuticular layer, presence or absence of hypodermis, structure of spongy mesophyll, thickness of palisade and spongy mesophyll layers, as well as types of raphides, and in the structure and forms of petioles. A combination of these characters may be useful in species identification. This study shows that there is some variation in petiole and leaf morphological and anatomical characters among the 22 taxa of Philodendron. However, many characters are present in all of them and may be typical of the genus. The study revealed several detailed interesting epidermal and anatomical features that have not previously been reported in the genus.

Relationship between plant species richness and age of woodland patches (Ojcow National Park, Poland)

Woodlands in different regions of Central Europe are mosaics diversified by floristic richness and age. The age of woodlands is understanded as the period of permanent existence of woodland phytocenosies, or at least a woodland site, without any transformations, even for a short period of time, to agricultural fields or any other areas managed in different ways. Forests which occur in identical habitats are often differentiated of their species richness. Data gathered from studies carried out to date, indicate that the age of a forest plays a significant role in the way plant communities develop. This relationship, however, is modified by a number of other factors. In this paper, an attempt was made to answer the following questions: 1) are there any differences in this relationship between woodland age and richness, and species composition of recent and ancient forests, 2) does the age of a forest affect the richness of vascular plant species in the layers of their vertical structure, the number of species of various phytosociological groups, 3) which of the selected factors affecting the processes of migration and colonization, alongside age, affect the richness of species noted in forest communities. The Ojców National Park (OPN) was chosen as a study area because its forests are diversified by age, from the younger than 71 to the older than 216 years and because the history of the forests there have been well documented. Age of selected woodland patches was determined using a ‘Map of distribution woodlands of different age in the Ojców National Park’, whereas the remaining factors were either measured or determined in the field or using available sources. In order to establish relationships, a multiple regression model was used.The results obtained in the study prove that, in OPN, the age of the forest is the principal factor affecting the overall number of vascular species. Old forests are most abundant in species, and many plant taxa occur only in such forests. Within the same age classes, the number of taxa is often diversified because of the impact of habitat factors e.g., humidity, and it is also linked to the history of the development of these forests. The factors which affect the species richness in a particularly beneficial way is the presence of rocks, as well as the diverse relief of a given area. Much less significant are exposure and inclination of the terrain. The age of a forest significantly affects the number of species in the herb layer, whereas it does not demonstrate significant correlations with respect to shrub or tree layers. The number of species in fertile deciduous forests are also positively affected, whereas no such relations were found in coniferous forest species. The results also indicate that the forest’s surface area, along with a specific combination of factors, may only have a limited effect on the richness of plant species in the area.

The paper reports chromosome numbers for 13 taxa of Elatine L., including all 11 species occurring in Europe, namely E. alsinastrum, E. ambigua, E. brachysperma, E. brochonii, E. californica, E. campylosperma, E. gussonei, E. hexandra, E. hungarica, E. hydropiper, E. macropoda, E. orthosperma, E. triandra originating from 17, field-collected populations. For seven of them (E. ambigua, E. californica, E. campylosperma, E. brachysperma, E. brochonii, E. hungarica, E. orthosperma) the chromosome numbers are reported for the first time. With these records, chromosome numbers for the whole section Elatinella Seub. became available. Although 2n = 36 was reported to be the most common and the lowest chromosome number in the genus, our data show that out of thirteen species analyzed, six had 36 chromosomes but five species had 54 chromosomes, and the lowest number of chromosomes was 18. These data further corroborates that the basic chromosome number in Elatine is x = 9.

Większość z produktów naftowych działa toksycznie na organizmy żywe, w tym na rośliny, zwierzęta a także na człowieka. Szczególnie groźne dla środowiska są przepracowane oleje silnikowe ze względu na ich zanieczyszczenie. Celem pracy było określenie wpływu przepracowanego oleju silnikowego na wzrost i rozwój wybranych gatunków roślin. Badano wpływ przepracowanego oleju silnikowego w glebie w dawkach 0,5, 1, 10,50, 100 g na 1000 g gleby na przyrost części nadziemnych oraz masę części nadziemnych i podziemnych kupkówki pospolitej (Daetylis glomerata L.), wyki siewnej (Vicia sativa L.), i gorczycy białej (Synapis alba L.). Na podstawie wyników przeprowadzonych badań stwierdzono, iż obecność przepracowanego oleju silnikowego wpływa na ograniczenie wzrostu roślin. Zwiększenie dawki ksenobiotyku spowodowało zmniejszenie masy części nadziemnych i podziemnych roślin użytych w doświadczeniu. Badane gatunki wykazały zróżnicowaną wrażliwość na zanieczyszczenie gleby przepracowanym olejem silnikowym.

The aim of the investigation carried out in 2006-2007 was to assess differences between 5 grass species and 5 species of plants belonging to meadow herbs in their ability to accumulate selenium. According to the results, among the grass species, the samples of Arrhenatherum elatuis L. had the highest average Se content (46 μg Se⋅kg-1 d.m.), and the lowest average Se amount was found in Holcus lanatus L. (24 μg Se⋅kg-1 d.m.). The content of Se in meadow weeds (70 μg Se⋅kg-1 d.m.) was approximately twice as high as in grasses (32 μg Se⋅kg-1 dm.). Among this group of plants, the highest Se accumulation occurred in Equisetum arvense L. (103 μg Se⋅kg-1 dm.) and the lowest – in Taraxacum officinale (59 μg Se⋅kg-1 dm.). Both in grasses and in meadow weeds, the Se content significantly depended on the amount of this element in soils. In the following species: Dactylis glomerata L., Arrhenatherum elatius L., Poa pratensis L. and Taraxacum officinale, the amount of accumulated Se was also conditioned by the soil’s abundance in organic and total C.

Celem badań prowadzonych w latach 2006-2007 było określenie zróżnicowania w zdolności nagromadzania selenu przez 5 gatunków traw oraz 5 gatunków roślin zaliczanych do ziół łąkowych. Wykazano, że wśród analizowanych gatunków traw najwięcej selenu zawierały próby Arrhenatherum elatuis L. (46 μg Se⋅kg-1 sm.), a najmniej Holcus lanatus L. (24 μg Se⋅kg-1 sm.), średnio dla badanych gatunków roślin. Zawartość Se w chwastach łąkowych (70 μg Se⋅kg-1 sm.) była ok. 2-krotnie większa niż określona dla traw (32 μg Se⋅kg-1 sm.). W tej grupie roślin największą kumulację Se wykazywał Equisetum arvense L. (103 μg Se⋅kg-1 sm.), najmniejszą Taraxacum officinale (59 μg Se⋅kg-1 sm.). Zarówno w trawach, jak i chwastach zawartość selenu była istotnie zależna od ilości tego pierwiastka w glebach. Dla gatunków: Dactylis glomerata L., Arrhenatherum elatius L., Poa pratensis L. oraz Taraxacum officinale o ilości nagromadzonego Se decydowała również zasobność gleb w C-org. i S-og.

Twinflower (Linnaea borealis L.) is a widespread circumboreal plant species belonging to Linnaeaceae family (previously Caprifoliaceae). L. borealis commonly grows in taiga and tundra. In some countries in Europe, including Poland, twinflower is protected as a glacial relict. Chemical composition of this species is not well known, however in folk medicine of Scandinavian countries, L. borealis has a long tradition as a cure for skin diseases and rheumatism. It is suggested that twinflower has potential medicinal properties. The new study on lead secondary metabolites responsible for biological activity are necessary. This short review summarizes very sparse knowledge on twinflower: its biology, distribution, conservation status, chemical constituents, and describes the role of this plant in folk tradition of Scandinavian countries.

Zimoziół północny (Linnaea borealis L.) jest szeroko rozpowszechnionym gatunkiem cyrkumborealnym, należącym do rodziny Linnaeaceae (wcześniej Caprifoliaceae). Licznie rośnie w tajdze i tundrze. W kilku krajach Europy, także w Polsce, zimoziół został objęty ochroną gatunkową jako relikt glacjalny. W medycynie ludowej krajów skandynawskich L. borealis cieszy się długą tradycją stosowania w chorobach skórnych i reumatycznych, co wskazuje na potencjalne właściwości lecznicze omawianego gatunku. Jego profil chemiczny jest słabo poznany, dlatego wskazane są nowe badania głównych metabolitów wtórnych, które mogą być odpowiedzialne za aktywność biologiczną surowca. Niniejszy artykuł stanowi krótki przegląd dostępnej literatury, podsumowując skromną wiedzę na temat L. borealis z zakresu biologii, występowania, ochrony gatunku, obecności związków czynnych, stosowania w medycynie tradycyjnej i miejsca tego gatunku w kulturze krajów skandynawskich.

The paper presents results of a survey of natural monuments in the Śrem county, Poland. The survey inventoried eight avenues, 30 tree clusters, six erratics, two localities of a protected plant species, and 85 trees-natural monuments. Among all trees the most numerous group comprised small-leaved limes (447 trees – 36.6%), horse chestnuts (372 Aesculus hippocastanum – 30.4%) as well as Acer platanoides and Quercus robur (with 99 trees each – 8.1%). Among single trees classified as natural monuments the greatest numbers belong to Quercus robur (34 trees – 40.0%) as well as Aesculus hippocastanum and Tilia cordata (with 8 trees each – 9.4%). In the area of the survey there are 30 clusters of trees registered as natural monument. These clusters comprise 99 trees belonging to eight species. Among them English oaks vastly predominate – 65 trees (65.7%). Eight avenues are composed of 1038 trees belonging to seven species. The avenue with the highest number of trees is situated in Przylepki (the Brodnica comune), extending for 1.5 km and composed of 265 Tilia cordata specimens. Former manor and palace parks in the Śrem county account for 33% trees-natural monuments and 63% tree clusters. Considerable differences were recorded in the numbers of natural monuments registered in individual decades – in the 1950’s nine natural monuments were established (6.9% total number of natural monuments), in the 1960’s – one (0.8%), the 1970’s – one (0.8%), the 1980’s – 41 (31.3%), the 1990’s – 73 (55.7%), while in the first decade of the 21st century six natural monuments were registered (4.6%).
