Pozycja Open Access Właściwości chemiczne gliniastych gleb uprawnych o zróżnicowanej rzeźbie terenu z uwzględnieniem zbiorowisk roślinnych po piętnastu latach odłogowania. Część I. Właściwości chemiczne gleb(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Malinowski, Ryszard; Niedźwiedzki, Edward; Kutyna, Ignacy; Meller, Edward; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe fifteen year period of the fallowing of a loamy soil of a differentiated land relief caused an increase, as compared with the results of the studies carried out in 1994, in the soil acidity in all the studied elements of the relief. After such a long period of fallowing, no distinct changes were observed in humus resources, in the C : N ratio and in the content of available phosphorus. Whereas the resources of available potassium and magnesium increased in the soil layer up to a depth of 60 cm.Pozycja Open Access Segetal flora of the plantations of virginia fanpetals Sida hermaphrodita (L) Rusby in Łobez commune (West Pomerania)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Bacieczko, Wanda; Borcz, Agnieszka; Department of Meteorology and Landscape Architecture, West Pomeranian University of Technology, Szczecin; Department of Meteorology and Landscape Architecture, West Pomeranian University of Technology, SzczecinThis paper presents the results of the investigation of the segetal flora accompanying the Virginia fanpetals crops in Łobez Commune. The purpose of this research was the identification and ecological analysis of weeds recorded in two plantations of the species cultivated for biomass energy production. The origin of the weeds was also determined, based on their geographical-historical classification. As a result, a total of 106 vascular plant species were recorded. The number of species was different in both plantations depending on the fertilising manner. The first plantation which was fertilised with industrial effluents from the starch factory “Przedsiębiorstwo Przemysłu Ziemniaczanego Nowamyl” in Łobez, was characterized by lesser diversity of the segetal weeds (42 taxa) than the second plantation, which was not fertilised (95 taxa). Both plantations were dominated by perennial species (78 taxa), which were twice as numerous as annual plants (28 taxa). In both plantations weeds were mostly represented by ruderal species of the Artemisietea vulgaris class and segetal species of the Stellariete mediae class. Apophytes were the most numerous historicalgeographical group in the flora (78 taxa – 73.6% of the flora), whereas non-synantrophic spontaneophytes were rare. Archaeophytes were the most numerous species (16 taxa) amongst the anthropophytes – most of them were the weeds of cereal crops and root crops. Inboth plantations also the American neophytes were recorded: Solidgo canadensis, Conyza canadensis, and Erigeron annuus, which are classified as invasive species in Poland.Pozycja Open Access Comparison of growth, bulbs yield and nutrient content of Eucomis autumnalis (Mill.) Chitt., E. bicolor Baker and E. comosa (Houtt.) Wehrh. grown in a greenhouse as pot plants(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Salachna, Piotr; Department of Horticulture, West Pomeranian University of Technology, SzczecinEucomis species are a relatively new pot plants with potential for expansion. The aim of the study was to compare the growth, flowering, bulbs yield and macronutrients content of three species: Eucomis autumnalis, E. bicolor and E. comosa. The experiment was conducted in 2013 and 2014 in a greenhouse. The bulbs were planted in 18 cm diameter pots containing a deacidified peat, supplemented with a fertilizer Hydrocomplex. Of all the species tested, E. autumnalis had the least leaves, flowered earliest and produced the highest number of adventitious bulbs. E. bicolor had the highest number of leaves, produced longer and wider inflorescences and the least number of adventitious bulbs as compared to the other two species. E. comosa was characterized by the largest diameter of adventitious bulbs and the highest potassium content in the leaves. The analysis of the macronutrient composition of three Eucomis species showed that the leaves contained more nitrogen, phosphorus, potassium, magnesium and calcium than the bulbs.Pozycja Open Access Colonization of selected rose varieties by pests and pathogens(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Adamska, Iwona; Dzięgielewska, Magdalena; Department of Ecology, Environmental Protection and Development, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, SzczecinThe occurrence of pests and microscopic fungi on roses in the “Rożanka” City Garden in Szczecin was investigated in the years 2014–2015. Rosa thea hybrida (varieties ‘Alchymist’, ‘Aspirin Rose’, ‘Blaze Superior’, ‘Carina’, ‘Die Welt’, ‘Fairy’, ‘Flamingo’, ‘Flammentanz’, ‘Gloria Dei’, ‘Goldstern’, ‘Ingrid Bergman’, ‘Mr Lincoln’, ‘Muttertag Orange’, ‘Santana’ and ‘Sommerwind’), R. x centifolia (‘Petit De Holand’ variety) and R. rugosa were selected for analysis. Species composition and colonization degree by pests and by fungi were evaluated. Colonization degree depended on the rose variety, observation date and presence of other biological factors. An antagonism between pests and microscopic fungi was detected. R. ‘Ingrid Bergman’ was a variety least inhabited by pests and fungi.Pozycja Open Access New localities of the rare species Monotropa hypophegea in West Pomerania(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Bacieczko, Wanda; Borcz, Agnieszka; Department of Meteorology and Landscape Architecture, West Pomeranian University of Technology, SzczecinThis study presents new localities of Monotropa hypophegea L. – a species rare to Poland and to West Pomerania. They were recorded in the Barlinek-Gorzow Landscape Park, in the vicinity of the Płonno village, which is situated eastwards, 6 km away from Barlinek. They occur in the mixed forests that belong to the Forest Inspectorate of Barlinek, in the forest sections: 705f, 708b, 709a, and 709b. Population of this species comprises over 300 specimens.Pozycja Open Access The influence of fertilisation urea phosphate on growth and yielding bush of two highbush blueberry cultivars (V. Corymbosum)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kozos, Karolina; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinAn interest in highbush blueberry cultivation is growing in the world. An increase in the demand causes high prices of fruits. The success of cultivation depends on providing soil with a low pH value to the plants. The study specifies the influence of different doses (30 and 60 kg N · ha–1) of physiologically acidic urea phosphate (17.7% N, 44.6% P2O5) on the growth and yield of highbush blueberry shrubs. The studies were carried out at the Department of Horticulture, West Pomeranian University of Technology in Szczecin, at a production plantation specialized in the cultivation of highbush blueberry. The bushes were planted in soil classified as sandy silts with the content of organic matter at 4.1–4.2%. The following parameters were measured in autumn: the height of the bushes, the length of one-year growths, the number of one-year shoots growing on roots, the green index, leaf area and yield, fruit weight and firmness. The use of urea phosphate influenced the increase in the yield and size of fruits of both highbush blueberry cultivars, it did not, however, influence the increase in the height of bushes and the length of one-year shoots. It stimulated the plants to produce shoots growing on roots and the formation of larger leaves with a higher green index value as compared to unfertilized plants.Pozycja Open Access Soil conditions and plant communities on the summit, the slope and the depression on the edge of west Oder(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kutyna, Ignacy; Malinowska, Katarzyna; Malinowski, Ryszard; Department of Ecology, Envinronmental Protection and Development, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology Szczecin; Department of Soil Science, Grassland and Environmental Chemistry, West Pomeranian University of Technology, Szczecin; Kutyna I., Malinowska K., Malinowski R. (2016). Soil conditions and plant communities on the summit, the slope and the depression on the edge of west Oder. Folia Pomer. Univ. Technol. Stetin., Agric., Aliment., Pisc., Zootech., 328(39)3, 123–158. doi 10.21005/AAPZ2016.39.3.1237 relevés were made in the area of West Oder western edge located between the village of Moczyły and the hamlet of Kamionka. Geobotanical study was conducted in three elements of the terrain. 17 relevés were made on flat tops of the edge with cereal cultivation, 11 on the southern and southeastern slope within long-term fallow, and 7 in the depression (with triticale cultivation). 4 outcrops were made along the transect from which samples were taken in order to determine basic soil parameters (grain size distribution, pH and CaCO3 content). Lathyro- -Melandrietum noctiflori segetal community was distinguished on the summit and it was internally diversified into the typical variant as well as Anthemis tinctoria and Melampyrum arvense. The slopes are inhabited by floristically rich Convolvulo arvensis-Agropyretum repentis phytocoenoses. It is characterised by species diversity resulting from the process of community transformation, which occurs on the slope of the habitat during secondary succession. Poo-Tussilaginetum farfarae phytocoenoses develop at the footslope (in the depression), which is characterised by different ecological conditions compared to the slope and the summit. With the use of phytoindicational properties of plant species and Ellenberg’s method the following mean values were determined: thermal relations of the habitat (T), humidity (W), pH of the soil (R), content of nitrogen (N) and biological activity of the soil (G). The warmest are the habitats on the slope (T = 2.5) and on the summit (T = 2.3). In the depression, the habitats are very cold (T = 1.8). The driest soils are those of the summit and the slope (W = 3.5). In the depression the soils are periodically wet (W = 2.4). The pH of the soil on the summit and the slope is alkaline (R = 4.2) and in the depression it is neutral (R = 3.8). The content of N in the soil of the summit and the slope is similar (N = 2.8–3.3), and slightly lower on the slope (N = 2.7) which is due to the loss of humus caused by surface water erosion occurring on the slope of the hill. The results obtained with this method are very close to the soil parameters obtained with analytical soil science methods.Pozycja Open Access Effect of calcium peroxide on oxidoreductase activities in soil contaminated with gasoline and diesel oil(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Stręk, Michał; Telesiński, Arkadiusz; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology SzczecinThis paper presents the study on assessment of the effect of calcium peroxide on activity of chosen enzymes: dehydrogenases, catalase and o-diphenol oxidase in soil contaminated gasoline or diesel oil. Laboratory experiment was carried out on loamy sang with Corg content 8.7 g ・ kg–1. Into soil samples different combinations of gasoline or diesel oil (at the dosage of 50 g ・ kg–1) and calcium peroxide (at the amounts of 100 and 200 mg ・ kg–1) were added. Samples were adjusted to 60% maximum water holding capacity, and they were incubated for four weeks in tightly closed glass containers at temperature of 20°C. In soil treated with CaO2 and petroleum products, soil oxidoreductase activities were measured on days 1, 7, 14 and 28. Soil contamination with gasoline decreased in all oxidoreductase activities, while contamination with diesel oil increased in dehydrogenases and caused slight changes in catalase and o-diphenol oxidase activity. Effect of CaO2 on oxidoreductase activities in soil uncontaminated and contaminated with gasoline and diesel oil proved diversified, and depended on enzyme, incubation time, type of petroleum product and calcium peroxide dosage. Application of CaO2 in soil contaminated with petroleum products caused mainly stimulation of dehydrogenases and catalase.Pozycja Open Access Factors affecting development of pioneering psammophilous Dune vegetation on Przytorska Sandbar (Nature 2000 site „Wolin and Uznam” PLH320019)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Wróbel, Mariola; Kowalski, Wojciech W. A.; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin; Department of Botany and Nature Protection, West Pomeranian University of Technology, SzczecinThe influence of selected environmental factors on shaping sandy beach habitats as a place for the growth of psammophilous and halophilous plants were the purpose of a research performed in the years 2013–2014 on Przytorska Sandbar (Natura 2000 area „Wolin and Uznam” PLH320019). The research was performed on a beach section, which was excluded from recreational use, and closely bordered with the external port basin of the Liquid Natural Gas terminal under construction, where also the abrasive influence of storm surges had been diminished. Research results indicated a dominant influence of aeolian sand material accumulation in shaping embryo dunes inhabited by pioneer species of psammophilous and halophilous plants - Elymus farctus subsp. boreoatlanticus and Honckenya peploides – species characteristic of the plant association of Honckenyo-Agropyretum juncei R.Tx. 1955, identifying the natural habitat of the initial stages of coastal white dunes (habitat code: 2110), the parts of which had been observed in the research area as a classically shaped form. The presence of Ammophila arenaria and Leymus arenarius creating initial forms of grassy vegetation association of Elymo-Ammophiletum indicated a proceeding stabilisation of embryo dunes – evolving into a foredune. A strong sea accumulation of sand material and simultaneous decrease of abrasive storm-tide influence enabled the development of an ecologically and geographically foreign species Salix daphnoides, diasporas of which were located in the area of lower beach.Pozycja Open Access The influence of shurbs cutting method on yielding and quality of the goji berries (Lycium barbarum L.)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kruczek, Arleta; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinIn the experiment were compared: the growth of shrubs, yielding, the physical parameters of fruits and their chemical composition depending on the method of cutting bushes – the amount of main shoots. Research material consisted of goji berries grown in Department of Horticulture Research Station of the West Pomeranian University of Technology in Szczecin. Goji berries (Lycium barbarum L.) are characterized by high potential of health promoting properties and nutritious. They have been extremely important part of traditional Chinese medicine for ages. They are used there as a very important part of a healthy diet, due to the appearance of the complex polysaccharide valuable LBP (Lycium Barbarum Polysaccharides). Cutting of shoots stimulated growth of shrubs. Bushes cut into 3 shoots grew with larger number of shorter basal shoots, while the one-year shoots were the longest. The leaves of the cut bush were darker (L* = 39.8 and 41.2) and had a higher green index (42.1 and 44.8), in comparison to uncut bushes (L* = 37.3, SPAD = 43.5). It was also found that there is a significant correlation between the green index and the value of the parameter a* (r* = 0.92). Cutting of shrubs, especially into 3 shoots, reduced yielding however influenced increasing the size of the fruit.Pozycja Open Access Effect of preharvest use of anti-cracking preparations on changes in selected parameters of sweet cherry fruits during frozen storage(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Telesiński, Arkadiusz; Mikiciuk, Grzegorz; Mikiciuk, Małgorzata; Stręk, Michał; Płatkowski, Maciej; Statkiewicz, Małgorzata; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology SzczecinThis paper presents the study on comparison of the changes of dry weight content, total polyphenols content, total flavonoids content, and antioxidant activity in sweet cherry fruit in frozen storage, depending on the used preharvest anti-cracking preparations. The study material was sweet cherry fruits of the ‘Burlat’ cultivar, that were treated with anti-cracking preparations. In fresh fruits and during their frozen storage at temperature –25°C (after 60, 120, and 180 days), the mentioned parameters were determined. The preharvest use of anti- -cracking preparations caused an increase in total flavonoids content, and antioxidant activity was observed. In plant untreated anti-cracking preparations, decrease in antioxidant parameters were observed. The preharvest use of during frozen storage deepened the decrease of total flavonoids content and antioxidant activity but limited the changes in the content of dry weight and total polyphenols. The analysis of the kinetic degradation demonstrated that total flavonoid content was characterized by higher stability in the fruits, which were not treated with anti- -cracking preparations. An opposite trend was determined for total polyphenols content.Pozycja Open Access Glycoalkaloid content in the tubers of potato manured with undersown catch crops in the integrated and organic production system(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Makarewicz, Artur; Płaza, Anna; Gąsiorowska, Barbara; Opatowicz, Natalia; Department of Agrotechnology, University of Natural Sciences and Humanities in Siedlce,; Department of Agrotechnology, University of Natural Sciences and Humanities in Siedlce,; Department of Agrotechnology, University of Natural Sciences and Humanities in Siedlce,; Department of Agronomy, West Pomeranian University of Technology, SzczecinThe paper presents results of studies carried out in 2006-2009 to determine the effect of the biomass of undersown catch crops, which were either autumn-incorporated or left on the soil surface as mulch for spring incorporation, on glycoalkaloid content in the tubers of potato grown in the integrated and organic production system. An experiment was conducted to examine the following two factors: 1. manuring with undersown catch crops: control (no undersown catch crop), farmyard manure, white melilot, white melilot + westerwolds ryegrass, westerwolds ryegrass, white melilot – mulch, white melilot + westerwolds ryegrass – mulch, westerwolds ryegrass – mulch; 2. production system: integrated and organic. Glycoalkaloid content was determined in potato tubers by means of the Bergers method. The lowest glycoalkaloid content was determined in potato tubers manured with white melilot and a mixture of white melilot and westerwolds ryegrass, either autumn- or spring-incorporated, as well as westerwolds ryegrass left on the soil surface as mulch for spring incorporation. Potato tubers grown in the integrated production system contained less glycoalkaloids compared with organic potato.Pozycja Open Access Analysis of fluoride, dry matter contents and pH in sediments and surface water of Nowogardzkie lake(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Szydłowski, Kamil; Stręk, Michał; Department of Ecology, Environmental Protection and Development, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, SzczecinThe aim of study was to determine the impact of adjacent terrain usage on the fluoride content in sediments and others important ecological indicators. All of results applies to bottom sediments and surface water from Nowogardzkie Lake. The lake is partly within the Nowogard agglomeration and partly within farmlands. The total number of collected samples was 19 from sediments and 5 from surface water. The all samples were collected in January 2016. Higher concentrations of fluoride and organic matter content were recorded in agricultural adjacent area and pH of sediments was higher in city area. There was correlation between fluoride content in sediments and organic matter content. There was also negative correlation betwen pH in sediments and organic matter content.Pozycja Open Access The influence of soil differentiation on chemical composition of sea buckthorn (Hippophaë rhamnoides L.) leaves as feed material(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Jaroszewska, Anna; Biel, Wioletta; Jurgiel-Małecka, Grażyna; Grajkowski, Józef; Gibczyńska, Marzena; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of General and Ecological Chemistry, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of General and Ecological Chemistry, West Pomeranian University of Technology, SzczecinDue to the fact that sea buckthorn leaves could be a supplement to animal feed and food products, the present research aimed at determining the content of such elements as nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, lead, cadmium, nickel and copper in sea buckthorn leaves as well as establishing the relation between the elements content and soil composition. The leaf samples were collected in June 2014 from wild sea buckthorn shrubs (Hippophae rhamnoides L. ssp. rhamnoides) localised in four spots in Szczecin Poland. The data concerning the content of macronutrients (N, P, K, Ca, Mg) and micronutrients (Fe, Mn, Zn, Ni, Cu, Pb, Cd) in leaves of wild sea buckthorn (Hippophae rhamnoides L.) indicate that the leaves can be considered good animal feed material, comparable to grass and legumes. The fact that content of lead and cadmium in wild sea buckthorn leaves do not exceed the accepted norms for these elements is an another argument confirming its usefulness as an animal feed material.Pozycja Open Access Lavandula spp. essential oils – its use, composition and genetic basis of production(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Andrys, Dominika; Kulpa, Danuta; Department of Genetics, Plant Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Genetics, Plant Breeding and Biotechnology, West Pomeranian University of Technology, SzczecinLavender is mainly used in medicine, cosmetics industry, aromatherapy, perfume industry and as a culinary herb. It is most often grown for the purpose of obtaining essential oils characterized by a pleasant fragrance as well as antibacterial, antifungal and antioxidant properties. The present paper is an overview of information on essential oils obtained from plant tissue of the Lavandula genus, including the methods of extraction, chemical composition and potential use. The chemical composition of plant oil is determined by various parameters such as environmental conditions, growing season, harvest time, methods of drying and storing until the time of oil extraction, method of oil isolation as well as the specific conditions of the analysis (column, set temperature) used to identify the compounds.Pozycja Open Access Analysis of influence farming systems on chemical composition of four variety of triticale winter (xTriticosecale Wittm. ex A. Camus) grain(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Gibczyńska, Marzena; Dawidowski, Andrzej; Sobolewska, Magdalena; Jaroszewska, Anna; Lewandowska, Leokadia; Department of General and Ecological Chemistry, West Pomeranian University of Technology, Szczecin; Grupa Azoty Zakłady Chemiczne „Police” SA, Police; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of General and Ecological Chemistry, West Pomeranian University of Technology, SzczecinThe aim of the study carried out on the basis of a field experiment was to compare results obtained during cultivation of winter triticale in the organic and conventional farming systems. Comparing these two systems (organic with conventional), changes in the content of macroelements (phosphorus, potassium, calcium, magnesium), and microelements (manganese, iron, zinc and copper) were analyzed in the triticale grain. The study involved four triticale varieties: Benetto, Cultivo, Grenado, and Moderato. The field experiment was performed in 2010–2011 at The National Research Institute for Fisheries Affairs Mecklenburg – Vorpommern in Gulzow, Germany. Grain of all triticale varieties grown in an organic systems contained more phosphorus and magnesium. Compared tillage systems did not differentiate calcium and potassium in grain of triticale Benetto, Cultivo, Grenado, and Moderato varieties. No relationship was found between the total content of phosphorus, calcium and magnesium vs. cultivars. The total potassium content in triticale grain was differentiated by the varietal factor. The triticale grain of all tested varieties (Benetto, Cultivo, Grenado, and Moderato) grown in organic system was characterized by higher – by ten or so per cents – iron, zinc, manganese, and copper contents as compared to the conventional systems.Pozycja Open Access Microbiological air rating in a variety of objects during treatment of the post-slaughter poultry wastes.

The air samples were collected at 4 dates from 5 different locations – buildings (building for pre-processing with chemical treatment, pool for liquid waste, facility for storage of sludge from biological sewage treatment, object for preparation of waste subject to composting, and proper composting facility). Analyses were carried out in accordance with the procedures of environmental microbiology. Number of total bacteria was determined with particular emphasis put to Pseudomonas sp. and Clostridium sp. as well as Actinomycetes sp. Based on the air assays, it was found that the bacterial bioaerosol was present in varying degrees depending on the selected groups of microorganisms and differed between dates of analyzes and research points i.e. type and purpose of the object for these wastes management.Pozycja Open Access Evaluation of the biological value of the dandelion leaves (Taraxacum officinale weber ex wigg.) grown on soil contaminated with copper(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Studziński, Mateusz; Grzeszczuk, Monika; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinThe experiment was conducted in 2013. Research material included the leaves of a dandelion (Taraxacum officinale Weber ex Wigg.) – roots with the above-ground part, gathered before tying of flower baskets (Taraxaci radix cum herba). Laboratory analyses, which were the continuation of the pot experiment, were conducted in the laboratory of the Department of Horticulture of the West Pomeranian University of Technology in Szczecin. In the dried plant material (dandelion leaves) the content was determined: of dry mass and total ash, vitamin C as L-ascorbic acid, chlorophyll a, b and total, total carotenoid and antioxidant activity. Based on the obtained results it was found that both the biometric features of the dandelion plants and their biological value subjected to significant changes depending on the amount of copper contained in the soil and the crop harvest date.Pozycja Open Access The effect of different doses of fertilisation with phosphorus, potassium and nitrogen on seed yield of Dactylis glomerata L. of ‘Tukan’ variety(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kitczak, Teodor; Czyż, Henryk; Kirkiewicz, Anna; Department of Soil Science, Grassland and Environmental Chemistry West Pomeranian University of Technology, Szczecin; Department of Soil Science, Grassland and Environmental Chemistry West Pomeranian University of Technology, Szczecin; Department of Soil Science, Grassland and Environmental Chemistry West Pomeranian University of Technology, SzczecinThe study was conducted at the Lipki Agricultural Experiment Station in Lipnik near Stargard Szczeciński on acid brown soil formed of light glacial sand on clay (5 Bw pgl : pgm), which is characterised by low content of humus on Ap level (1.57–1.59%) and clay particles (11.9–12.4%). The field experiment was set up in split-plot system in four replications, with an area of a single plot of 12 m2. The study included two factors: I – doses of phosphorus and potassium (P + K kg . ha–1): 60 + 120 and 90 + 180, II – doses of nitrogen (N kg . ha–1): 0, 40, 80 and 120. The experiment was established in 2010 by sowing Dactylis glomerata seeds of ‘Tukan’ variety (8 kg . ha–1) in spring barley harvested for grain. The study included two years of seed collection (2011 and 2012). The study determined plant density in the years of full use, number of generative shoots per plant, inflorescence length, number of spikelets and seeds per inflorescence as well as seed and straw yield. Biometric observations were conducted in 25 randomly selected inflorescences from each plot. Seed and straw yield was determined on the area of each plot during seed harvest. Dactylis glomerata of ‘Tukan’ variety was characterised by higher level of yields in the first than in the second year of seed collection. The obtained results indicate, that when establishing a plantation on light soil with companion planting in spring barley, it is advisable to use 120 kg N, 60 kg P and 120 kg K . ha–1. The increased phosphorus-potassium fertilisation (90 kg P and 180 kg . ha–1) did not change the studied morphological features of plants (number of generative shoots per plant, length of inflorescence, number of spikelets and seeds per inflorescence), while fertilising with nitrogen in doses of 40, 80 and 120 kg . ha–1 had a positive effect on increasing the above mentioned features.Pozycja Open Access Interactive effects of salinity stress with or without nicotinamide on physiological and biochemical parameters of tomato seedling(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Krupa-Małkiewicz, Marcelina; Ostojski, Dominik; Sędzik, Maja; Pelc, Justyna; Smolik, Beata; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, SzczecinThe aim of this study is to determine the effect of both NaCl and KCl salt alone or in combination with nicotinamide, on growth and some biochemical parameters of Vilma cultivar of tomato under laboratory and field conditions. The combinations of salt solutions used had a negative impact on the ability of seed germination and morphological characteristics of 14-day-old tomato seedlings. The addition of NaCl salt had a positive impact on the content of Chl a and Car in contrast KCl salt solution led to the decrease of photosynthetic and non- -photosynthetic pigments. Under field conditions, NaCl salt solution exhibited inhibitory effect on plant growth, concentration of Chl a, Chl b, and Car, simultaneously increasing oxidative stress parameters (proline and malondialdehyde – MDA). Moreover, leaves of tomato from the control group were darker in comparison to the remaining plants. It was observed that the addition of nicotinamide to the solution did not show protective effect on plants grown under salinity, except in a small increase of the concentration of proline.
