Pozycja Open Access Analiza możliwości prognozowania barwy polędwicy wołowej poddanej obróbce cieplnej, prowadzonej w piecu konwekcyjno-parowym, na podstawie składowych barwy mięsa surowego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Guzek, Dominika; Głąbska, Dominika; Wierzbicka, Agnieszka; Zakład Techniki w Żywieniu, Katedra Żywności Funkcjonalnej i Towaroznawstwa Wydział Nauk o Żywieniu Człowieka i Konsumpcji, Szkoła Główna Gospodarstwa Wiejskiego w Warszawie; Zakład Dietetyki, Katedra Dietetyki, Wydział Nauk o Żywieniu Człowieka i Konsumpcji Szkoła Główna Gospodarstwa Wiejskiego w Warszawie; Zakład Techniki w Żywieniu, Katedra Żywności Funkcjonalnej i Towaroznawstwa Wydział Nauk o Żywieniu Człowieka i Konsumpcji, Szkoła Główna Gospodarstwa Wiejskiego w WarszawieThe aim of the research was to assess the possibilities of beef tenderloin colour prediction in RGB colour system, after thermal treatment conducted in steam-convection oven in constant conditions, on the basis of beef colour before thermal treatment, using the computer image analysis. It was observed, that G and B components of colour of beef tenderloin before thermal treatment were correlated with G and B components of browned surface of meat after treatment. In case of R component of colour of browned surface of meat and all components of colour of meat after thermal treatment, no correlation with colour of meat before treatment was observed. It may be concluded, that prediction of beef tenderloin colour after thermal treatment may be impossible, because it depends on degree of doneness (tenderloin rare, medium, well done), but prediction of colour of browned surface of meat seems to be a promising direction in researches.Pozycja Open Access Charakterystyka wybranych elementów środowiska przyrodniczego wyspy Chełminek część I: różnicowanie się cech morfologicznych i właściwości gleb powstających z piaszczystych osadów dennych w wyniku ich zalesienia na wyspie Chełminek(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Malinowski, Ryszard; Niedźwiedzki, Edward; Kowalski, Wojciech A; Protasowicki, Mikołaj; Meller, Edward; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe island Chełminek was formed artificially mostly of sand bottom sediments obtained after the construction and deepening of the fairway Świnoujście–Szczecin and was afforested about 100 years ago. In this study the properties of sand sediments under forest were compared with similar mechanical composition of “fresh” sand sediments. Forest cover brought about the development of muck soil profile with horizons Amu-AC-C-Cgg. The upper part of this profile at the depth of 3–20 cm, in comparison with “fresh” sediments, was characterised by: the accumulation of organic matter (50,4–98,0 g · kg–1), strong acidity (pHKCl 3,1–3,8), reduced bulk density (0,84–1,24 Mg · m–3), increased total porosity (45,8–53,6%), a clear increase in available potassium as well as potassium and phosphorus soluble in the mixture of concentrated HNO3 + HClO4 acids.Pozycja Open Access Inuletum Ensifoliae Kozł. 1925 w obrębie opuszczonego kamieniołomu „Piotrawin”, położonego na krawędzi Wisły(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Kutyna, Ignacy; Malinowska, Katarzyna; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Fizjologii Roślin, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieXerothermic grasslands found in Poland are precious phytocenoses increasing biodiversity. They are generally settled on small surfaces, mainly on strongly insolated (southern, south western and south eastern exposure), i.e. on dry and warm slopes. They are also found on slopes of completely exploited quarries. Limestone substrata (including Seon marls) are optimum settlements for the development of grassland communities including the floral association of Inuletum ensifoliae. The studies were carried out on two terraces of unused quarry "Piotrawin" during the years 2001 and 2011. The quarry was reclaimed by technical and biological methods in 1995 and 1996. On the slopes two terraces were formed on which a series of xerothermic grasslands species were introduced (including Linum flavum, Inula ensifolia). In both years the terraces were settled by phytocenoses of the Inuletum ensifoliae association. Characteristic and distinguishing species of the Festuco-Brometea (34 taxa) classes are dominant in them. Patches of the community are settled by such species of ruderal (Artemisietea vulgaris) and seminatural (Molinio-Arrhenatheretea) communities. In the structure of the association of 2011 the contribution of species of these phytosociological classes decreased significantly. Reduced were also the species of segetal communities (Stellarietea mediae class), whereas slightly more species of scrub communities (Rhamno-Prunetea class) were observed in the association. In 2011 the cover of a series of species of the Festuco- -Brometea class: Anthyllis vulneraria ssp. polyphylla, Sanguisorba minor, Medicago falcata, Salvia verticillata, Euphorbia cyparissias, Thymus pulegioides and others inceased distinctly. After 10 years a series of species that were introduced during biological land reclamation are not found in the community. As far as shrubs are concerned, Cornus sanguinea were not found, and as regards herbage, Adonis vernalis, Stipa capillata and Aster amellus did not occur. The remaining species introduced during land reclamation settled in the phytocenoses in both years of the studies. The process of succession that takes place in the Inuletum ensifoliae community stabilizes its structure and floristic composition. A potential threat to this community can be the invasion of the species of scrub communities, mainly those of the Pruno-Ligustretum association.Pozycja Open Access Jakość owoców dwóch odmian winorośli oraz wpływ sposobu ich maceracji na barwę moszczu(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Ochmian, Ireneusz; Chełpiński, Piotr; Rozwarski, Rafał; Strzelecki, Roman; Pantecki, Paweł; Angelov, Ludmil; Stalev, Bojan; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Winiarstwa, Uniwersytet Rolniczy w Plovdiv, Bułgaria; Katedra Winiarstwa, Uniwersytet Rolniczy w Plovdiv, BułgariaThe research was conducted in the years 2010–2011 at the Fruit Farming Laboratory of the West Pomeranian University of Technology in Szczecin. Two cultivars of grapevine were examined, Regent and Cabernet Sauvignon. The size of clusters and fruits, the content of extract and organic acid and juice yield of the grape must obtained were examined. The changes of grape must colour in the process of warm (20–22oC) and cold (7–10oC) maceration were evaluated. It was shown that the Regent cultivar was characterized by larger fruits. Grapes from this cultivar also had a higher content of organic acids, vitamin C and yielded more juice, compared to Cabernet Sauvignon fruits. However, a lower extract content was found in Regent cultivar fruits. It was also found that the temperature of grape must maceration affects its colour. The release of dark dye from grape skins occurred more rapidly during warm maceration. More substances which give wine its red colour were found in the grape must prepared from Cabernet Sauvignon fruits. The measurement performed on the last day of maceration of both cultivars under analysis, regardless of the temperature at which this process was conducted, revealed the highest value of the b* parameter which defines the blue colour.Pozycja Open Access Jakość sensoryczna mięsa wieprzowego zapeklowanego metodą zalewową solankami o różnym składzie(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Balejko, Jerzy Andrzej; Kowalski, Michał; Czerniejewska-Surma, Barbara; Balejko, Edyta; Zakład Inżynierii Procesowej i Maszynoznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Inżynierii Procesowej i Maszynoznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Podstaw Żywienia Człowieka, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe estimation of quality changes of raw and cooked pork meat pickled previously by immersion method with taking advantage four curing solution differing with the chemical composition was investigated. The pointed method of appearance, smell, colour and texture of raw meat were applied. Additionally after the thermal treatment the taste was evaluated. Moreover the colour profiling analysis (raw meat and after thermal treatment) and palatability tests (cooked meat) were taken. The estimation was made after 24, 129 and 216 hours. The pickling time and the kind of applied curing solution have no impact of the pork loin on the general estimation before and after thermal treatment. Thermal treatment has impact on the colour profile of loin only in case of immersion method of pickling.Pozycja Open Access Liczebność drobnoustrojów w glebach skażonych olejem napędowym i poddawanych procesowi fitoremediacji(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Hawrot-Paw, Małgorzata; Nowak, Andrzej; Beker, Paulina; Zakład Mikrobiologii i Biotechnologii Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Mikrobiologii i Biotechnologii Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Mikrobiologii i Biotechnologii Środowiska, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe paper presents results of research evaluating the influence of the phytoremediation of soil contaminated with diesel fuel on the numbers of the three main taxonomic groups of soil microflora. Two species of plants have been used in studies: red fescue (Festuca rubra) varieties Areta and red clover (Trifolium pratense) varieties Nike. Quite variable factors in the experiment was also the soil type and incubation time. It was found that microorganisms showed different sensitivity in the presence of diesel fuel in the soil and remediation treatments. Stimulatory effect of phytoremediation was reported There has been stimulating effect phytoremediation for bacteria and actinomycetes in sandy soil and unclear reaction for fungi, irrespective of plant species and soil type used in the experiment.Pozycja Open Access Occurrence and Biological Activity of Lectins in Seeds of Leguminous Plants and Cereals(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Brinken, Anna; Piątek, Jarosław; Biel, Wioletta; Sagan, Zygmunt; Department of Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Forensic Medicine Institute, Pomeranian Medical University in Szczecin; Department of Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Forensic Medicine Institute, Pomeranian Medical University in SzczecinMateriał do badań stanowiły nasiona roślin strączkowych i ziarna zbóŜ.

Compared two methods of indirect determination of half life time and estimation accuracy of the calculations. These were the analytical method (for example, a simple first-order reaction model) and the graphical method (assuming a linear decay of the active substance). According to the current international standards assume that a measure of uncertainty of measurement was the double value of standard deviation. Calculated expanded uncertainty of measurement of the absolute half period and the relative uncertainty. Depending on the method used was different, but similar half-life values (36.1 and 37.3 days). It was found that the analytical method was more accurate (relative uncertainty 3.0%) than the graphics (uncertainty 4.8%).Pozycja Open Access Ocena odrastania muraw trawnikowych z udziałem śmiałka darniowego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Jankowski, Kazimierz; Jankowska, Jolanta; Sosnowski, Jacek; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w SiedlcachThe aim of this work was to evaluate the usefulness of tufted hairgrass to establish turf lawns used extensively as a result of the impact of it’s on the degree of lawns regrowth. Field experiments were founded in April 2003. In one experiment were sown the seeds of five grass species in pure sowing on the plot with an area of 1 m2. It was tufted hairgrass, clump red fescue, rhizomes red fescue, tall fescue, kentucky – bluegrass. In the second experiment were sown mixtures of this grass species with tufted hairgrass. Seeds for these experiments came from IHAR in Radzików. In the first experiment, research factors were 5 species of grasses and 3 date of observation and in the second – 5 kind of mixtures and 3 date of observation. As a date for observation for the spring was adopted mid-May, for the summer mid-July, for the autumn mid-October. The study was conducted in the years 2004–2005 by making systematic observations once a season (spring, summer, autumn). Each year of the study the lawns regrowth were evaluated. This evaluation was made according to the COBORU methodology. Valuation used 9o scale, where 9 meant the best value of this feature. Regrowth of tufted hairgrass turf was slower than kentucky bluegrass or red fescue, and so this species which are commonly used in lawn mixtures with varying suitability. From the five lawn mixtures established on the tufted hairgrass base, a mixture consisting of 50% of the tufted hairgrass and red fescue the slowest regrowth was characterized. The slow regrowth rate of tufted hairgrass both in monoculture and in mixtures create the possibilities to use this grass species in greater extent to the establish of lawns especially those that will not require too frequent mowing.Pozycja Open Access Ocena ubocznego oddziaływania spinosadu na aktywność oksydazy o-difenolowej w glebie(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Telesiński, Arkadiusz; Płatkowski, Maciej; Zakład Biochemii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Biochemii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieInto the loamy sand and sandy loam introduced the insecticide Spintor 240 SC, containing active substance spinosad, in the field dose, 5, 10 and 25 times larger. After treatment soil of spinosad o-diphenol oxidase activity was significant changed, but effect of spinosad was not connected with dose of insecticide. Effect of spinosad depended on soil properties: in loamy sand induced stimulation, but in sandy loam induced inhibition of o-diphenol activity.Pozycja Open Access Oddziaływanie hydrożelu i rodzaju okrywy glebowej na aspekt ogólny muraw trawnikowych(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Jankowski, Kazimierz; Sosnowski, Jacek; Jankowska, Jolanta; Kowalczyk, Renata; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Pracownia Agrometeorologii i Podstaw Melioracji Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach, Wydział Przyrodniczy, Instytut Agronomii; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w SiedlcachThe aim of this work was to determine the effect of superabsorbent Aqua–Gel P4 on the dynamics of lawns emergence. The experiment was established in 2007. The studies were carried out on the base of two lawn experiments. The first experience was a monoculture lawn where in pure sown four species of lawn grasses were studied. In the second experiment four designed mixtures the same grass species were used. The type of used soil cover (cultivated soil or garden peat) did not cause significant variation in the general aspect of both lawn grasses sown in pure stand and in mixtures. The best general aspect, undepend on the kind of soil cover or kind of subsoil had the mixtures lawns with domination of red fescue, perennial ryegrass, common bent. The monoculture turfs had the best general aspect on the plots with 5 cm of placement depth of hydrogel, and mixtures turfs by 10 cm. The kind of soil cover hadn’t any significant influence on improving of general aspectPozycja Open Access Parametry fizyczne mieszanek kamienno-glebowych polecanych do uprawy drzew i krzewów w aglomeracjach miejskich i terenach zdegradowanych(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Malinowski, Ryszard; Kubus, Marcin; Meller, Edward; Wojcieszczuk, Marta; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Dendrologii i Kształtowania Terenów Zieleni, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Gleboznawstwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieOne method of improving the conditions for growth and development of urban trees is the use of stone and soil mixtures called structural soils. Studies provided by various authors indicate that beside the salinity the main factor of trees decaying is excessive soil compaction and lack of appropriate water-air relations.The aim of the research was to determine the basic physical parameters of two structural soils: Hydralit ZN – Baustoffe GmbH, Baumsubstrat and Hydralit ZU – Baustoffe GmbH, Baumsubstrat's Tegra. The study showed that the structural soil Hydralit ZN is classified as a very strong skeletal soil and skeletal-sandy. This structural soil is characterized by the bulk density of 1.37–1.46 g · cm–3, the total volumetric water capacity 35.4–37.7% capillary water capacity 25.49–30.16% and air porosity 5.22–10.71%. The second of the analyzed structural soil – Hydralit ZU, consists mainly of gravel, which was attributed to the very skeletal. It is characterized by high total porosity 35.39–40.61%, non-capillary porosity – 9.80–17.53% and capillary porosity – 22.53–27.58%. The physical properties of both substrates ensure correct water-air properties and mechanical ones for proper rooting and growth of trees.Pozycja Open Access Porównanie wybranych kinetycznych modeli zanikania herbicydów w glebie(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Gregorczyk, Andrzej; Swarcewicz, Maria; Katedra Agronomii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Syntezy Organicznej i Technologii Leków, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe aim of the paper was to used of three types of mathematical function: the single first-order degradation kinetics (SFO), Gustafson and Holden model (FOMC) and the simple linear bi-phase model, for quantification of the fate of pesticides in soil. For instance data from laboratory study of dissipation of atrazine in soil was used. Numerical methods using for estimate of structural coefficients of degradation models of this herbicide. For every models assessed the values of 50, 90 and 100% dissipation time of substance active. Mathematical equations and figures of first derivative of functions were presented as the analysis of atrazine degradation process. Accomplishment of estimate adequately of using models. To the last degree of the kinetics criterions of degradation of substance active and the statistics criterions make good the Gustafson and Holden model. In this work find that analysis of degradation rate is valuable of study integration of kinetics degradation herbicides in soil.Pozycja Open Access Porównanie zdolności konkurencyjnych w stosunku do chwastów oraz plonów ziarna pszenicy orkisz (Triticum aestivum ssp. spelta) z odmianami pszenicy zwyczajnej (Triticum aestivum ssp. vulgare) w ekologicznym systemie produkcji(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Feledyn-Szewczyk, Beata; Zakład Systemów i Ekonomiki Produkcji Roślinnej, Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, ul. Czartoryskich 8, 24-100 PuławyThe aim of the study was to assess the competitive potential against weeds and grain yield of spelt wheat (Triticum aestivum ssp. spelta) as compared to varieties of common wheat (Triticum aestivum ssp. vulgare) under organic farming conditions. The study was conducted in the years 2005–2007 at the Experimental Station of IUNG – PIB in Osiny (Lublin province), on a field used in organic way since 1994. The varieties of spelt wheat: Schwabenkorn (2005 and 2007) and R12 (2006) and varieties of common wheat: Kobra, Mewa, old variety Ostka Kazimierska were cultivated. Species composition, number of weeds and their dry matter were assessed in tillering and dough stage. Biometric analysis of wheat plants and plant canopy architecture were also done. The smallest dry matter of weeds in dough stage was recorded in spelt wheat Schwabenkorn, old variety of common wheat – Ostka Kazimierska and modern variety – Mewa. High competitive potential against weeds of spelt Schwabenkorn and Ostka Kazimierska was associated with the morphological features such as the biggest height, tillering, leaf area and leaf area index (LAI). The smallest ability to compete with weeds and the higher level of weed infestation was noted in Kobra and spelt R12. Despite of the favorable parameters of growth and development of spelt Schwabenkorn and Ostka Kazimierska, affecting their competitiveness against weeds, they have small yielding potential. The average grain yields of modern varieties: Kobra and Mewa were about 4 t · ha–1 in organic system.Pozycja Open Access Potencjał allelopatyczny wyciągów wodnych z chwastów w stosunku do siewek pszenicy ozimej i żyta(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Komorowska, Anna; Wrzesińska, Eleonora; Bochyński, Paweł; Zakład Uprawy Roli i Roślin, Katedra Agronomii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Uprawy Roli i Roślin, Katedra Agronomii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Uprawy Roli i Roślin, Katedra Agronomii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe purpose of this research was to determine the influence of water extracts derived from weeds: wild horsetail (Equisetum arvense L.), nettle (Urticae dioica L.) and their mixtures on different levels of concentration (0; 1; 2; 3%), by soaking and watering the grain on the germination ability and the initial growth of the winter wheat (Triticum aestivum L.) and rye (Secale cereale L.). Results showed that, water extracts from the wild horsetail had a greater impact on the checked parameters of both the winter wheat and rye, than the extracts derived from nettle and their mixtures. Used water solutions from weeds compared with the distilled water hindered the initial growth of plants; reduced the germination ability, length and mass of seedlings, in addition the solutions with the most inhibitory interaction were the ones with the highest concentration (3%). Solutions, with lower concentration of 1 and 2% had similar interactions with the range of checked parameters, especially a length of seedlings and their mass. However the way of application of water solutions had a greater impact on the parameters of winter wheat rather than rye’s. Soaking the wheat in comparison with watering caused the reduction of the grains germination capacity, but increased length and mass of seedlings. In case of rye soaking increased the mass of seedlings.Pozycja Open Access Przydatność Festuca pratensis i Trifolium pratense do podsiewu łąki na glebie organicznej(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Czyż, Henryk; Kitczak, Teodor; Stelmaszyk, Anna; Zakład Łąkarstwa i Melioracji, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Łąkarstwa i Melioracji, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Łąkarstwa i Melioracji, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieStudies were carried out in 2003–2007 on the meadow with the community of Festuca rubra, on the rot soil proper. In the meadow experiment two factors were studied – the dose of nitrogen (0, 60, 120, 180 kg · ha–1) and the grass-leguminous mixtures of seeds, with different participation of Festuca pratensis and Trifolium pratens1 e (1 – without sowing – control, 2 – Festuca pratensis – 100% – 30 kg · ha–1), 3 – Festuca pratensis – 70% + Trifolium pratense – 30%, 4 – Festuca pratensis – 50% – Trifolium pratense – 50%, 5 – Festuca pratensis – 30% + Trifolium pratense – 70% 6 – Trifolium pratense – 100% – 18 kg · ha–1). Analysis of the floristic composition of sward showed that the proportion of Festuca pratensis increased when seed quantity and nitrogen dose were enlarged, but there was no such regularity in the case of Trifolium pratense. Its share declined independently of the factors of the experiment in the subsequent study years. Between used combinations of experimental factors, the most productivity in terms of dry matter yield were objects sawed with mixture – 70% Festuca pratensis and 30%, Trifolium pratense and Trifolium pratense alone, fertilized with nitrogen doses of 120 and 180 kg · ha–1. Feed of individual objects characterized by similar chemical composition. The concentration of majority of analyzed elements (N, P, K, Ca, Mg, and Cu, Zn, Fe, Mn) corresponded to the level recommended for a good feed. Only the content of zinc and copper fluctuated below the norm, but phosphorus and potassium – it greatly exceeded.Pozycja Open Access Reakcja wybranych odmian żyta ozimego na stres wywołany różnymi czynnikami abiotycznymi(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Smolik, Beata; Zakład Biochemii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe pot experiment was conducted in laboratory conditions. The soil used in experiment was loamy sand with 1.2% of organic carbon. To individual soil samples the following solutions were added 2.5 mM Pb(NO3)2 (207 mg Pb+2), 30 mM NaF (570.0 F– ), 0.05 mM H2SeO3 (3,95 Se4+), aqueous emulsion of Izoturon 500 SC herbicide in an amount of 6.5 mm3 · kg–1 soil. The aim of this study was to determine the influence of chosen pollutants on biometric parameters and SOD activity in three winter rye cultivars. Substances applied to the soil significantly reduced growth, fresh weight and superoxide dismutase activity in three winter rye cultivars planted in contaminated soil in comparison with control plants. Rye cultivars were characterized by different tolerance to chosen substances. It was found that cultivar ‘Chrobre’ was more sensitive to introduced pollutants than ‘Skat’ and ‘Dańkowskie Diamant’.Pozycja Open Access Response of Lycopersicum Peruvianum L. Line to Salinity in Vitro Culture(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Szczepaniak, Małgorzata; Kulpa, Danuta; Department of Plant Genetic, Breeding and Biotechnology, The West Pomeranian University of Technology, Szczecin; Department of Plant Genetic, Breeding and Biotechnology, The West Pomeranian University of Technology, SzczecinTrzy linie Lycopersicum peruvianum L. (LA0462, LA1692, LA4316), rozmnożone z nasion zebranych w Peru i Chile, poddane były działaniu stresu solnego w kulturach merystemów i kalusa in vitro. W pierwszym etapie badań, na pożywkę MS z dodatkiem 25 do 150 mM NaCl wykładano fragmenty wierzchołkowe pędów. W drugim doświadczeniu na pożywkę z dodatkiem NaCl w stężeniu od 75 do 150 mm wykładano fragmenty tkanki kalusowej. Kontrolę stanowiły fragmenty roślin i tkanka kalusowa, wyłożona na pożywkę bez dodatku NaCl. Badane linie zareagowały w różny sposób na dodatek soli do pożywki. Dodatek NaCl do pożywki w stężeniu od 25 do 75 mM NaCl wpłynął korzystnie na wysokość roślin L. peruvianum, liczbę wykształconych liści, masę badanych roślin i kalusa linii LA0462. W przypadku linii LA1692 różnice we wzroście były mniejsze (nieistotne statystycznie), choć dodatek NaCl działał korzystnie na rozwój roślin i przyrost tkanki kalusowej. Wartości wszystkich cech morfologicznych roślin i kalusa trzeciej z badanych linii – LA 4316 – rosnących na pożywkach z dodatkiem NaCl, były niższe od kontroli.Pozycja Open Access Seed Germination and Plant Development of Bletilla Striata in Vitro(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Kulpa, Danuta; Katroń, Joanna; Department of Plant Genetic, Breeding and Biotechnology, West-Pomeranian University of Technology; Department of Plant Genetic, Breeding and Biotechnology, West-Pomeranian University of TechnologyCelem badań było opracowanie metody kiełkowania nasion in vitro i regeneracji chińskiej rośliny leczniczej – bletilii pasiastej (Bletilla striata). Stwierdzono, że do kiełkowania nasion tego storczyka w kulturach in vitro najbardziej odpowiednia jest poźywka Knudson "C" (Knudson 1946) bez dodatku roślinnych regulatorów wzrostu. Kiełkujące w kulturach in vitro siewki winny być regenerowane na podłoźu według Knudsona (1946) z dodatkiem 0,2 mg · dm–3 NAA. Zregenerowane rośliny, wysadzone w podłoźe firmy Hollas, są zdolne do wzrostu w warunkach szklarniowych.Pozycja Open Access Wpływ chemicznego i mechanicznego zwalczania Taraxacum officinale na zawartość NDF i ADF w runi łąkowej(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Jankowska, Jolanta; Pracownia Agrometeorologii i Podstaw Melioracji, Uniwersytet Przyrodniczo-Humanistyczny w SiedlcachThe aim of this study was determine the effect of different methods of Taraxacun officinale control on the fraction of fibers, namely NDF and ADF in the meadow sward. Experiment was founded in 2007 on permanent grasslands in the śelków village near Siedlce (geographical coordinates: 52º08'N and 22º11'E) and was conducted until 2009. The field experiment was set up in randomized blocks in 3 replications. Experimental factors were two mechanical methods of Taraxacum officinale control by the pulling and mowing, and four selected herbicides (Rancho EC 242, Bofix EC 260, Starane 250 EC and Mniszek 540 SL). Plot area was 9 m2 . In each growing season three cuts were harvested. In the studies the content of fiber fractions NDF and ADF in meadow sward were determined. Used chemical methods of Taraxacum officinale control may affect on the feed uptaking, especially on the objects where herbicide Mniszek was used. It’s is evidenced by the highest content of neutral-detergent fiber fractions in the feed in compare to other objects. The feed from the objects with the mechanical method of Taraxacum officinale control the lowest digestibility was characterized. From chemical methods of dandelion control, the greatest influence on fooder digestibility had Starane herbicide (fluroksypyr in the form of ester 1-methylo heptylov).
