Pozycja Open Access Dendroflora of Gryfino(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Nowak, Grzegorz; Nowakowska, Małgorzata; Department of Meteorology and Landscape Architecture, West Pomeranian University of Technology, Szczecin, Poland; Department of Meteorology and Landscape Architecture, West Pomeranian University of Technology, Szczecin, PolandThe aim of the thesis was to acquaint oneself with the dendroflora of Gryfino. The research was carried out between 2009 and 2010 and in 2013. Out of 279 taxons specified to their as species and a variety, 5.0% are plants of European origin, 22.6% – plants occurring naturally in Europe and outside of Europe, 15.0% are plants of Asian origin, 11.8% – plants occurring naturally in North America, 4.7% are hybrids, and 40.9% – domesticated plants (cultivars). Out of trees and shrubs rarely cultivated in Poland, there are for example Abies grandis, Abies procera ‘Glauca’, Picea omorika ‘Pendula’, Cedrus libani subsp. atlantica ‘Pendula’, Pinus ponderosa, Pinus wallichiana, Metasequoia glyptostroboides, Cryptomeria japonica, C. japonica ‘Elegans’, Berberis julianae, Berberis verruculosa, Crataegus persimilis ‘Splendens’, Gleditsia triacanthos, Ilex aquifolium, Viburnum ×pragense, Viburnum rhytidophyllum, Catalpa bignonioides, Campsis radicans, Clerodendron trichotomum. There are few trees reaching monumental sizes: 8 gymnosperm trees belonging to 2 taxons and 12 angiosperm trees belonging to 7 taxons.Pozycja Open Access Effects of Cadmium and Salinity-Sodicity on Acid and Alkaline Phosphatase Activity with Reference to Ecological Importance of Soil Pollution(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Telesiński, Arkadiusz; Stręk, Michał; Śnioszek, Martyna; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin, Poland; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin, Poland; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin, PolandThe aim of the study was to determine the changes of the acid and alkaline phosphatase activity in the soil caused by the presence of cadmium and NaCl. The experiment was carried out in the laboratory condition, on soil samples taken from the arable-humus horizon of Gumieniecka Plain black earths. Granulometric composition of this soil was sandy loam. The organic carbon content was 1.09%, total nitrogen content was 0.14% and pH in 1 M KCl 6.81. Various concentrations of Cd(NO3)2 and NaCl were introduced to soil samples. The amount of cadmium added to the soil was 0, 1, 5 and 25 mg Cd2+ · kg–1 , and the amount of NaCl was 0 and 0.5% of soil weight. On day 1, 7, 14, 28 , 56 and 112 alkaline and acid phosphatase activity was determined spectrophotometrically. The obtained results are converted with respect to the enzyme activity in the soil controls (assuming it to be 100%) and given as percent of inhibition. The results were shown as environmental danger zones graphs. The activity of acid and alkaline phosphatase changed significantly after addition of cadmium and sodium chloride to the soil. Both, cadmium and salinity of the soil, caused inhibition of phosphatase activity, which increased with enhancing concentration of metals in the soil. Sodium chloride intensified the negative effect of cadmium on phosphatase activity in the soil. Observed inactivation of phosphatases caused by 25 mg Cd2+ · kg–1 of Cd ranged, on the graphs of ecological danger zones, in the area of critical values, which may indicate that cadmium disturbs the metabolism of phosphorus compounds in soil.Pozycja Open Access Plant Communities on the Flat Ridge of the “Piotrawin” Quarry Located in the Vicinity of Vistula Near Józefów on the Vistula in Opole Lubelskie County(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Kutyna, Ignacy; Malinowska, Katarzyna; Department of Environmental Protection and Development, West Pomeranian University of Technology, Szczecin, Poland; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin, PolandIn 1998, three years after technical and biological reclamation, 29 relevés were made in the ridge area (the crown of the excavation) of the quarry “Piotrawin”. Two segetal associations were distinguished (Sileno inflatae-Linarietum minoris and Lathyro-Melandrietum noctiflori) as well as one xerothermic grassland association (Inuletum ensifoliae). The communities are floristically very rich. The number of taxa in the individual associations is varied and it ranges from 120 (Lathyro-Melandrietum noctiflori) to 147 (Sileno inflatae-Linarietum minoris). The average number of taxa in a relevé of individual communities is very high and it ranges from 60 to 62. The dominant syntaxon in these communities is Stellarietea mediae, the number of taxa ranges from 26 to 39. Moreover, the communities are characterised by a numerous participation of ruderal communities species (Artemisietea vulgaris), xerothermic grasslands (Festuco-Brometea) and seminatural grasslands (Molinio-Arrhenatheretea). The aforementioned communities have close mutual floristic similarities determined on the basis of the degree of phytosociological stability. High mutual similarity, at the level of 76.8%, is demonstrated by segetal communities. Smaller mutual similarity (72.1%) occurs between Sileno inflatae-Linarietum minoris and Inuletum ensifoliae. After three years, the segetal communities were still dominant in the researched ridge area of the quarry, but during a reconnaissance performed in 2013 a significant floristic transformation of the community was noted, which tends to the infestation of the area with xerothermic grasslands communities species and scrubs of Rhamno-Prunetea class.Pozycja Open Access Quality Assessment of Composts and Lettuce from Allotment Gardens of West Pomeranian Voivodeship(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Meller, Edward; Jadczak, Dorota; Strutyński, Wojciech; Lewandowska, Lucyna; Olesiak, Adrian; Department of Soil Science, Grassland and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Poland; Department of Soil Science, Grassland and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, Poland; Department of Soil Science, Grassland and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, Poland; Department of Soil Science, Grassland and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, PolandThe purpose of studies was to determine chemical properties of composts and content of macro- and microelements of butterhead lettuce (Lactuca sativa L.), cultivar Królowa Majowych, from allotment gardens of West Pomeranian Voivodeship. Chemical analysis included pH, content of organic matter, organic carbon, total nitrogen and total sulphur as well as total amount of macro- and microelements. The assessment of lettuce quality was based on macro-and microelement content in leaf dry matter. A characteristic feature of allotment garden compost is a low content of organic matter and a lower level of macroelements, total nitrogen and carbon, in comparison with the composts from mixed municipal wastes. The majority of composts are mature and stable but C : N ratio turned out to be unfavourable. Heavy metal content in these composts was low, except for one sample with an elevated level of lead. The lettuce cultivated on these composts has poor resources of calcium and phosphorus but optimum content of potassium and magnesium. The lettuce leaves contained a high level of sodium and one sample -an elevated amount of lead.Pozycja Open Access The New Locality of Ranunculetum Fluitantis Allorge 1922 Plant Community and Species of Rhodophytes in the Myśliborka Stream (The Natura 2000 Site „Ostoja Wkrzańska” Plb 320014)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Kowalski, Wojciech W. A.; Wróbel, Mariola; Banaś-Stankiewicz, Urszula; Komarzewska, Katarzyna; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin, Poland; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin, Poland; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin, Poland; Provincial Inspectorate for Environmental Protection in Szczecin, Szczecin, PolandDescribed the border site of Ranunculetum fluitantis Allorge 1922 plant association in the Myśliborka stream documents the new location of "Lowland and foothill rivers with batrachion vegetation communities Ranunculion fluitantis (code – 3260)" in Western Pomerania and in the Natura 2000 site "Ostoja Wkrzańska" PLB 320014. In waters of the stream verified the presence of rare species of hydrophytes positions such as shiny pondweed Potamogeton rutilus and freshwater rhodophytes: Batrachospermum atrum and B. gelatinosum. The occurrence of these taxa in waters of the stream indicates the oligo-and mesotrophic nature of the habitat which confirmed results of hydrochemical analysis of waters.
