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 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).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 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 Zawartość histaminy w owocach. Doniesienie(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Czerniejewska-Surma, Barbara; Surma, Orina; Plust, Dominika; Bienkiewicz, Grzegorz; Zakład Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieHistamine is well known biogenic amine. This amine plays an important role in the human body and may pose a risk to human health and life. Knowledge of the histamine content in food products and consequences of its formation are very important for food technologist. The aim of this study was to determine the histamine content in the fruits from polish plant and from import. Material for the analyses were: pome fruits, stone fruits, berries, nuts and tropical fruits. Histamine content was determined by the colorimetric method according to PN-87-A-86784. The amount of histamine ranged from 2.15 to 31.04 mg · kg–1. The highest content of histamine was observed in lemons. Among the studied groups of fruits contain the most of histamine content have pome fruit, then nuts, tropical fruits, berries and stone fruits. The obtained results show that none of the studied fruits did not contain histamine above of allowable limits.Pozycja Open Access Wpływ zróżnicowanej dawki odpadu popieczarkowego na stopień odrostu muraw trawnikowych(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Jankowski, Kazimierz; Czeluściński, Wiesław; Jankowska, Jolanta; Sosnowski, Jacek; Wiśniewska-Kadżjan, Beata; 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; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w SiedlcachTo fertilize both grassland and lawns can be used refuses from mushrooms cultivation. Utilization mushroom’s refuses is still very little known. The aim of this study was to determine the effect of mushroom’s substrate on the compactness of turf lawn with varying participation of perennial ryegrass. The field experiment was established in 2004 on agricultural object of University of Natural Sciences and Humanities in Siedlce. It was tested the type of lawn mixtures: Wembely (M1); Parkowa (M2), Relax (M3), Półcień (M4), and the mushroom’s substrate in different dose (0, 2, 4, 6 kg · m–2). On the all experimental objects mineral fertilization in the form of Pokon fertilizer was used. In each year of the study the lawn compactness was evaluated. This evaluation was made according to the IHAR methodology. Among the studied lawn mixtures the quickest regrowth was characterized Wembley mixture with 80% share of perennial ryegrass, and generally with a decreasing of the percentage of perennial ryegrass in the mixture, the regrowth decreased. In a view point of the lawns owner it’s a favorable feature. Increasing the dose of mushroom’s refuse also increased regrowth of turf lawns but it caused a further improvement in the condition of subjects such as lawn color, compactness etc. which has been confirmed in other studies.Pozycja Open Access Wpływ podłoża na ukorzenianie się sadzonek zielnych i zdrewniałych borówki wysokiej odmiany Bluecrop(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Ochmian, Irenusz; Saniewska, Adrianna; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe research was conducted at the Fruit Farming Laboratory of the West Pomeranian University of Technology in Szczecin to study the effectiveness of the rooting ability of softwood cutting and hardwood cutting of the highbush blueberry in substrates containing peat, perlite and sand. The percentage of cutting taking root as well as the number and length of roots and the chlorophyll content index were determined. It was found that the reproduction of the blueberry plants of the Bluecrop cultivar was more effective if hardwood cutting were used (64%). Peat perlite and the mixture of the two were the best substrates to cause hardwood cutting and softwood cutting to take root. They had the highest percentage of plants taking root (from 55% to 83%) and the largest number of roots (from 7 to 14). The longest roots were formed in plants grown in substrates prepared from peat and perlite (106 mm) and also in peat alone (110 mm), especially softwood cutting (132–141 mm), which grew roots almost twice as long as those in hardwood cutting. Moreover, the chlorophyll content index (SPAD) was also higher (approx. 50).Pozycja Open Access Wpływ zasolenia wybranych podłoży na wzrost i kwitnienie krwawnika pospolitego (Achillea millefolium L.) I krwawnika wiązówkowatego (Achillea filipendulina Lam).(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Janicka, Dorota; Dobrowolska, Agnieszka; Katedra Ogrodnictwa, Pracownia Roślin Ozdobnych, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ogrodnictwa, Pracownia Roślin Ozdobnych, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieExperiments which determined the influence of salinity and medium on the growth, development and quality of two yarrow species were conducted in the years 2008–2009. Achillea millefolium and Achillea filipendulina seedlings were sown in September, 7 months before the beginning of the experiments constituted the research material. Young plants in their vegetative phase were planted before April 10 in five substrates – deacidified peat was the first substrate; 10, 20 and 30% of zeolite was added to the three next ones, respectively, and a mixture of acidic peat and mineral soil 1:1 v/v constituted the last substrate. The Azofoska fertilizer was used at a dose of 5 g dm–3. 3 weeks after planting when the root system regenerated, the plants began to be watered with a NaCl solution with EC 6.3 mS cm, obtained by adding 3.4 g of NaCl to 1 dm3 of water. The salinization was performed for four consecutive weeks, once a week. For the fernleaf yarrow was used 300 ml, and for the common yarrow was used 500 ml of the working liquid per pot. The amount of the working liquid depended on the size of the pots. The salinization process was ended after phytotoxicity symptoms occurred on plants. It was found that the use of salt slightly stimulated the growth of the common yarrow and also increased the mass of the above-ground parts. Poorer and delayed flowering of plants treated with the NaCl solution was observed for the fernleaf yarrow. The partial browning and drying of shoot tips was observed in both species, which slightly reduced their decorative value.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 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.
