Pozycja Open Access Struktura geograficzno-historyczna flory oraz jej stopień synantropizacji w fitocenozach leśnych przylegających do parkingów oraz występujących w ich obrębie(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Kutyna, Ignacy; Malinowska, Katarzyna; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Fizjologii Roślin, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieChanges in the flora of natural forest communities forming in the areas between the forest and a roadside car park or the forest and a forest car park and in the phytocenoses of car parks were determined by enumerating anthropogenic indices of: natural character of flora, proper synanthropy and potential flora, proper and potential apophytization, proper and potential apophytism of spontaneophytes, general anthropophytisation, archeophytization of flora, kenophytization of flora, modernization of flora (M), stability of the flora of anthropophytes and stability of total flora and the indices of fluctuation changes in the flora of anthropophytes and in total flora of the studied phytocenoses. Communities deep in the forest in both habitats are characterised by considerably larger indices of natural character, as compared to the flora of phytocenoses of the area between the forest and the car park. The lowest natural character is shown by communities in the car parks. Whereas phytocenoses formed in the car parks show the highest indices of proper and potential synanthropization. This is the result of anthropogenic impact on these specific habitats. A direct penetration of the habitats of the forest adjacent to the car parks (ecotone zone) by travellers leads to a change in the structure of phytocenoses towards their synanthropization. This is confirmed by the indices of anthropophytisation, which are largest in the communities of the car parks. In the structure of the investigated communities, the contribution of archeophytes is small and in the phytocenoses of the forests they are not found at all. The occurrence of alien species (kenophytes) in the studied phytocenoses is not significant and this is confirmed by small indices of kenophytization. The flora of the examined communities shows a high degree of stability and fluctuation changes in anthropophytes and the entire flora of individual phytocenoses are not big. Only in phytocenoses in the car parks in the forest habitats, the index is a little larger due to the occurrence in them a larger number of diaphytes. The analysis of the spatial structure of anthropogenic indices of variability in the flora is of considerable cognitive significance. It facilitates verification of the space from the perspective of the natural character of the flora (the index of the natural character, synanthropization and apophytization) and also the expansion of alien species (the index of kenophytization and fluctuation changes). It also allows to determine the relative stability of the species composition (index of archeophytization and stability of the flora).Pozycja Open Access Wpływ następczy międzyplonów na plonowanie pszenżyta ozimego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Płaza, Anna; Soszyński, Jarosław; Katedra Szczegółowej Uprawy Roślin, Akademia Podlaska ul. B. Prusa 14, 08–110 Siedlce; Katedra Szczegółowej Uprawy Roślin, Akademia Podlaska ul. B. Prusa 14, 08–110 SiedlceThe paper presents the results of researches carried out over 2001–2005 which aimed at describing the sequent impact of undersown crops which were plowed down in autumn, stubble catch crops plowed down in autumn and left in the form of mulch till spring on yielding of winter triticale. The following combinations of intercrops were taken into account: control object (without intercrop), undersown crop – biomass plowed down in autumn (red clever, red clover + Italian ryegrass, Italian ryegrass), stubble catch crop – biomass plowed down in autumn (white mustard), stubble catch crop – biomass left in the form of mulch till spring (white mustard). Undersown crops were sown into spring barley which was cultivated on grain, and stubble catch crops were sown after its harvest. In the first year after catch crops applying the table potatoes were cultivated, in the second year winter triticale was cultivated. The results pointed that, catch crops with exception of red clover inserted into the soil the similar number of biomass. The highest number of nitrogen and phosphorus was supplied by red clover and by the mixtures of red clover with Italian ryegrass, the highest number of potassium was supplied by white mustard, the highest number of calcium was supplied by red clover, the mixtures of red clover with Italian ryegrass and white mustard, the highest number of magnesium was supplied by red clover. The conditions of the growing season significantly modified the yield of winter triticale. The highest grain yield and total protein from grain were achieved from the object where under the forecrop of winter triticale the mixtures of red clover with Italian ryegrass and Italian ryegrass were plowed down.Pozycja Open Access Technologia uprawy i plonowanie pszenżyta ozimego w środkowowschodniej Polsce(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Wielogórska, Grażyna; Turska, Elżbieta; Starczewski, Józef; Katedra Ogólnej Uprawy Roli i Roślin, Akademia Podlaska w Siedlcach; Katedra Ogólnej Uprawy Roli i Roślin, Akademia Podlaska w Siedlcach; Katedra Ogólnej Uprawy Roli i Roślin, Akademia Podlaska w SiedlcachThe work presents data collected by means of a survey carried out in the years 1998 and 2006 – in central-eastern Poland. There was observed an increase in the share of cereals in the structure of planted crops to the level of 82.4% the increase for triticale being 27.3%. A large share of cereals in rotations deteriorated the value of the land and reduced winter triticale yields. The yields were very low (on average 3.59–3.78 t · ha–1). However, in both years they were higher than the averages for Poland, which was a result of higher (than the average for Poland) mineral fertilization applied to the land. Winter triticale yields were mainly influenced by mineral fertilization, pesticides and soil quality. Higher yields were obtained on farms where higher fertilization was applied, pesticide applications were more frequent and triticale was cultivated on higher-quality soils.Pozycja Open Access Inheritance of Fertility Restoration in Winter Triticale with Cytoplasm of Triticum Timopheevi(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Góral, Halina; Stojałowski, Stefan; Tyrka, Mirosław; Wędzony, Maria; Katedra Hodowli Roślin i Nasiennictwa, Uniwersytet Rolniczy ul. Łobzowska 24, 31–140 Kraków; Zakład Genetyki, Hodowli i Biotechnologii Roślin, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Biochemii i Biotechnologii, Politechnika Rzeszowska al. Powstańców Warszawy 6, 35–959 Rzeszów; Instytut Fizjologii Roślin im. Franciszka Górskiego Polskiej Akademii Nauk ul. Niezapominajek 21, 30–239 KrakówWe investigated inheritance of a male fertility restoration in winter triticale with the sterilising cytoplasm of T. timopheevi. Generations F1, F2, and BC1 were derived from crosses between two male sterile lines with the cytoplasm T. timopheevi and 12 restorer inbred lines of S3–S14 generations. The distribution of fertile and sterile plants in segregating progenies indicates that at least four independent nuclear genes are involved in expression of fertility restoration. Male sterility was determined by recessive genes. The simultaneous presence of at least two dominant genes in two independent loci is required for fertility restoration. The precise determination of the role of identified loci on the base of obtained phenotypic distributions is difficult due to presence of plants with intermediate fertility and variation that can not be explained by simple segregation ratios.Pozycja Open Access Wpływ odłogowania na wybrane właściwości gleb piaszczystych(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Tomaszewicz, Tomasz; Chudecka, Justyna; Katedra Rekultywacji i Chemii Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Rekultywacji i Chemii Środowiska, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe authors investigated the humus horizon (0–20 cm) of rusty soils in period of agriculture use (winter barley crop) and after 8–10 years since its use abandonment. Those soils had texture of heavy loamy sands. The fallow soils had the lower content of available potassium, the lower values of pHKCl and bases saturation (V). The contents of available phosphorus and magnesium, exchangeable aluminum and organic carbon were higher than in period of agriculture use. The authors also ascertain the improvement of soil susceptibility on physical degradation – S(f) and destruction of structure (RDC).Pozycja Open Access Fitocenozy leśne występujące na parkingach przydrożnych i w ich sąsiedztwie w Puszczy Wkrzańskiej i Bukowej(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Kutyna, Ignacy; Juchniewicz, Iwona; Malinowska, Katarzyna; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Fizjologii Roślin, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe description of the forest phytocenoses was based on 69 phytosociological records taken in the areas of coniferous habitats and forest habitats. They were taken deep in the forest situated about 80 to 100 m from the car park (typical forest communities) and in the area of 1 to 10 m in width, adjacent to the car park (ecotone zone). The phytosociological records were also taken in the area of mid forest car parks. The aim of the studies is to determine types of communities and their structure (floristic composition, phytosociological stability (S) and cover coefficients (D) of species). Deep in the forest, in coniferous habitats (mainly in the mixed fresh forest) dominant are the patches of Leucobyro-Pinetum association, of Pomeranian-Silesian variety with a distinguishing taxon Deschampsia flexuosa. In the habitats of the mixed fresh forest the most numerous are the phytocenoses of the birch-oak forest (Betulo pendulae-Quercetum roboris), and as to the fresh forest, the most numerous is the community of fertile beech forest of Pomeranian type (Galio odorati-Fagetum). Communities within the ecotone zone are charecterised by partial rebuilding of the structure. The same communities as those in the ecotone zone are found deep in the forest, but there are more species of seminatural and synanthropic communities. Phytocenoses in car parks have a completely different structure. In the fresh coniferous habitats and in the mixed fresh coniferous habitats, patches of Sieglingio-Agrostietum alliance are observed, a part of which was classified as suballiance S.-A. poëtosum annuae. In fertile forest habitats, dominant are mainly patches of carpet community Lolio-Polygonetum arenastri, with a considerable contribution of the communities of Molinio-Arrhenatheretea, Artemisietea and Stellarietea mediae classes. It was also observed that the forest communities within the forest habitats are poorer floristically in comparison with phytocenoses of forest habitats. The richest floristically communities are the ones within the zone in which a car park is adjacent to the forest.Pozycja Open Access Zbiorowiska roślinne na obszarze zreklutywowanego wyrobiska Szczecin-Żydowce(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Kutyna, Ignacy; Czerwiński, Zbigniew; Młynkowiak, Elżbieta; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieA post-extraction gravel pit was subjected to technical reclamation where by the pit was filled with fly ash and covered by a 37–150 cm thick soil layer. Subsequently, biological remediation was applied: the area was sowed with Lolium perenne, Festuca pratensis, Dactylis glomerata, Poa pratensis, Phleum pratense and Trifolium repens. Ten years after the remediation treatments, 47 phytosociological relevès were taken. Two associations were identified: the Artemisio-Tanacetum vulgaris and the Calamagrostietum epigeji. In addition, the area was found to support the Arrhenatheretum elatioris dactylidetosum glomeratae subassociation and a community with Elymus repens. The presence of a total of 133 taxa was recorded. The communities were similar in their species richness which varied from 79 to 81 taxa per community. The lowest species richness (56 taxa) was found in the community with Elymus repens. Of those species introduced during remediation, only Dactylis glomerata proved very frequent, but occurred at small patches. Less frequent were Poa pratensis and Festuca pratensis. The remaining species occurred only sporadically; their development during the succession was limited, or they were eliminated altogether, by other taxa developing spontaneously, e.g., Elymus repens.Pozycja Open Access Ocena stanu zachowania wybranych populacji goryczki krzyżowej (Gentiana cruciata) na Pomorzu Zachodnim(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Piotrowska, Julia; Katedra Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieGentiana cruciata is a protected species which appears relatively rarely in xerotermic communities. The research on the population of this species was carried out in 2006. Number of specimens, density and spatial structure were examined on 5 × 5 m experimental areas. Floristic composition of phytocoenoses were characterized, too. In Kamieniec and Nawodna the population of Gentiana cruciata was found in Adonido-Brachypodietum pinnati communieties for which Gentiana is characteristic species. In Nawodna it is estimated on 1370 specimens. The greatest population of Gentiana cruciata appears on this area and its characteristic feature is the diversity of length of stems and the number of flowers. The numerous population from Kamieniec is characterized by the changebility of biometric parameters because of diversified habitat conditons. The population from Zdroje takes up the smallest area (106 specimens) where the most frequent blossoming was marked. The part of blossoming specimens was smaller because the worsening of light conditons. The aggregate type of spatial distribution was found in all examined populations.Pozycja Open Access Zawartość białka w ziarnie zbóż uprawianych w mieszankach z pszenżytem ozimym w zależności od stosowanej technologii uprawy(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Starczewski, Józef; Bombik, Antoni; Czarnocki, Szymon; Katedra Ogólnej Uprawy Roli, Roślin i Inżynierii Rolniczej, Akademia Podlaska ul.

Prusa 14, 08–110 SiedlceStudies were carried out in the years 2004–2007 at the University of Podlasie Experimental Station in Zawady. The factors investigated in the study were as follows: cultivation of cereal species (winter wheat, winter triticale and rye) in pure stand and in mixtures (numbers in brackets specify grain proportions of individual species at sowing), and cultivation system. A field experiment was designed as a split plot arrangement of treatments. The results obtained were subjected to analysis of variance and mean separation was obtained by the Tukey’s test. Mono-cropped winter wheat grain was characterized by the lowest protein content. Wheat cultivated in mixtures accumulated more protein in grain, the accumulation being particularly stimulated by competition with rye. Significantly more protein was obtained in the grain of intensivelycultivated wheat. No significant differences in winter triticale grain protein content were found resulting from competition with other species. On the other hand, there was confirmed significance of weather conditions in individual growing seasons, cultivation system and an interaction between the two factors. Significantly most protein was accumulated by triticale cultivated in the third study year. Like for wheat, increased fertilization significantly influenced triticale grain protein content, too. Response of rye was similar to the response of winter triticale. No differences were observed resulting from different proportions in mixtures. Significantly more protein in grain was associated with intensive cultivation. Moreover, significantly more protein was obtained in grain in the third study year, compared with the first year. Significantly most protein was recorded in the plots where wheat was cultivated in pure stand. In all the rye treatments there was observed a tendency towards reduction in protein yield, compared with triticale treatments.Pozycja Open Access Dwutlenek siarki w krajowych i importowanych napojach alkoholowych(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Buczek, Anna; Jankowska, Jowita; Jarosz, Dorota; Kalata, Anna; Ociepa, Andrzej; Protasowicki, Mikołaj; Staszewska, Hanna; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Toksykologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn period 2001–2006, the content of sulphur dioxide was determined in 90 assortments of wine and beer bought randomly at retail shops and wholesale outlets in Szczecin and West Pomeranian Province, Poland. Sulphur dioxide concentrations were analysed by titration after distillation from acidified samples. Sulphur dioxide was present in all the wines examined. The lowest concentrations, within the range of 1.2–18 mg SO2 · dm–3, were found in the domestic wines. Imported wines contained more sulphur dioxide, with concentrations varying from 4.4 to 217 mg SO2 · dm–3. The highest concentrations were detected in Rhine wines. Concentrations in beers ranged from 0.0 to 8 mg SO2 · dm–3. However in all the wines examined, sulphur dioxide concentrations were below the maximum permitted level, while in beers the detected values were below 10 mg · dm–3, which is the level of technological importance. Concluding the results, the wines and beers examined were safe for consumers’ health, considering sulphur dioxide content.Pozycja Open Access Influence of chemical mutagens on morphological traits in kalanchoe (Kalanchoe hybrida)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Krupa-Małkiewicz, Marcelina; ; Department of Horticultural Plant Breeding, West Pomeranian University of Technology, SzczecinW pracy określono zmiany fenotypowe i genotypowe u kalanchoe (Kalanchoe hybryda), wywołane azydkiem sodu (AS), siarczanem etylowo-metylowym (EMS), siarczanem metylowo-metylowym (MMS) i siarczanem dietylowym (DES), w stężeniach: 0,5; 1,0; 1,5 i 2,0 mM. Do oceny zmian genotypowych na poziomie DNA wykorzystano technikę ISSR-PCR. Otrzymane u kalanchoe zmiany to: rozrośnięte dno kwiatowe, różny kształt i liczba płatków kwiatu, przebarwienia na płatkach kwiatów od żółtego do pomarańczowego. Częstotliwość zmian zależała od zastosowanego mutagenu i jego stężenia w roztworze. Największą częstotliwość zmian otrzymano, stosując do indukowania mutacji DES w stężeniu 2,0 mM.Pozycja Open Access Porównanie metod przygotowania estrów metylowych kwasów tłuszczowych wg AOAC oraz metodą bezpośrednią przy oznaczaniu składu kwasów tłuszczowych tkanki mięsnej ryb(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Domiszewski, Zdzisław; Bienkiewicz, Grzegorz; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieAnalysis of the composition of lipids is done by separating fatty acids (FA), most often through gas chromatography, after converting FA into their volatile derivatives: fatty acid methyl esters (FAME). The aim of the paper was to compare the results of analysis FA composition of three species of oily fish, both raw and subjected to heat treatment, by converting FA into FAME applying the AOAC method, and using the direct method. FAME were separated by gas chromatography-coupled mass spectrometry (GC-MS). It was shown that, in fish subjected to heat treatment, the percentages of EPA and DHA whose FAME were prepared via the direct method were 5-10% higher than in case of applying the AOAC method. As far as uncooked oily fish are concerned, the method of obtaining FAME had no relevance to the composition of fatty acids. The method of obtaining FAME can have a substantial impact on the percentages of individual acids or acid groups in fat, and, in turn, on results of evaluation its nutritional value.Pozycja Open Access Wpływ mrożenia na proces dojrzewania odgłowionego i patroszenia śledzia bałtyckiego solonego metodą zalewową(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Tokarczyk, Grzegorz; Kołakowski, Edward; Bednarczyk, Bożena; Szymczak, Mariusz; Przybylska, Sylwia; Waliłko, Anna; Lament, Katarzyna; Krzywiński, Tomasz; Bienkiewicz, Grzegorz; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Towaroznawstwa i Oceny Jakości, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Technologii Żywności, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieRipening of fresh and frozen/thawed headed and gutted Baltic herring salted in 12% NaCl solution (brine) with or without the addition of 0.7% acetic acid was compared. Samples for assays were taken after 2, 3, 4, 5, 7, 10, 14, 18, 21 and 27 days of ripening. Control samples for assays were taken after 1, 3, 5, 7, 9, 11, 15 and 18 days of ripening. Herring meat and brine were assayed separately. Freezing of raw material reduced the growth of protein hydrolysis products (peptides and thyrosine), however the contents of peptides and thyrosine were high than in fresh fish, especially in brine and brine meat extract with acetic acid. Freezing of raw material had a significant impact on the ripening of Baltic herring salted in brine. Fundamental differences depended on initial processing and chemical composition of brine. Acetic acid inhibited ripening of salted frozen/thawed herring. Baltic herring salted in the presence of CH3COOH had better quality then salted in brine without CH3COOH regardless of initial processing. On the other hand the best quality had salted products made from fresh/unfrozen Baltic herring.Pozycja Open Access Wstępne badania nad zmianami warunków termicznych w krajobrazach podmiejskim i rolniczym(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Michalska, Bożena; Mąkosza, Agnieszka; Nidzgorska-Lencewicz, Jadwiga; Zakład Meteorologii i Klimatologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Instytut Technologiczno-Przyrodniczy w Falentach, Zachodniopomorski Ośrodek Badawczy w Szczecinie; Zakład Meteorologii i Klimatologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe study includes the analysis of hourly results of automatic measurements of air temperature measured at the level of 200 cm above the ground according to the real state time within the period from 1 December 2008 to 30 November 2009. The measurements were carried out at the agrometeorological station in Lipki near Stargard Szczeciński (agricultural area) and at the agrometeorological station in Ostoja situated on Gumieniecka Plain (suburban area of Szczecin). To determine the stimulating character of thermal conditions, the frequency of temperature changes from hour to hour and from day to day were calculated using 4 intervals of temperature: <2oC – changes indifferent to the organism, 2.1–4.0oC – sensible, 4.1–6.0oC – considerable and >6oC – sharp changes, and in the case of air temperature amplitude – 3 intervals – from 0 to 8.0oC – slightly sensible stimuli, from 8.1oC to 12.0oC - strongly sensible stimuli and >12.0oC – sharp stimuli. In both of the analysed areas, suburban and agricultural, the largest frequency of changes, from day to day as well as from hour to hour, occurred in the temperature interval 0–2oC. Large changes of air temperature >6oC, sharply affecting the organism of a human being, occurred mainly from day to day, most frequently in January, with a slightly larger percentage contribution of such days in the suburban area. The temperature changes from hour to hour were most frequently observed during a year in the morning between 8 am and 9 am and in the afternoon and in the evening between 4 pm and 9 pm. The largest number of strongly stimulating days (amplitudes above 12oC) were recorded in the suburban area in summer and in the agricultural area in spring. The obtained results show that the characteristic feature of the suburban area was larger thermal contrast, expressed by the frequency of interdaily and interhourly changes, as compared to the agricultural area.Pozycja Open Access Właściwości żywieniowe nasion szarłatu (Amarantus cruentus)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Biel, Wioletta; Jaskowska, Izabela; Zakład Żywienia Zwierząt i Żywności, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Żywienia Zwierząt i Żywności, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe nutritional value of the amaranthus seeds (Amaranthus cruentus L.) Aztek cv. was studied. Seeds contained about 17% protein, 8% fat, 3.5% ash and 6.5% crude fibre. The concentration of essential amino acids in crude protein were high. Crude protein had a high level of lysine – 4.72 g · 16g–1N. First limiting amino acid (CS) was isoleucine. All the estimated nutritional quality parameters based on amino acids composition showed that amaranthus protein had good nutritional quality, 93% – EAAI, 2.7 – predicted PER, 74 – predicted BV. Beneficial is also crude fat composition. Among amaranthus lipids the majority were unsaturated fatty acids (oleic – 25% and linoleic – 49%).Pozycja Open Access Wpływ stosowanej technologii uprawy i udziału pszenżyta ozimego w mieszankach na architekturę łanu(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Starczewski, Józef; Bombik, Antoni; Czarnocki, Szymon; Katedra Doświadczalnictwa, Hodowli i Nasiennictwa Roślin Rolniczych, Akademia Podlaska ul.

Prusa 14, 08–110 SiedlceA field experiment was conducted in the years 2004–2007 at the Experimental Farm in Zawady owned by the University of Podlasie. The experiment was a split-block design. The following factors were examined in the study: triticale proportion in a mixture and cultivation system. Variance analysis associated with the design was performed and means were separated using the Tukey’s test.The studies indicated that different cultivation systems had no significant influence on canopy architecture. Triticale proved to be more competitive than wheat although, when cultivated in mixture with rye, it did not manage to outcompete wheat. The greatest number of ears was harvested from mono-cropped plots and the plots under the mixture with equal shares of triticale and wheat. The longest were the stems of plants harvested in the year 2005 and plants cultivated in two- or three-species mixtures with a 50% share of rye. The presence in mixture of much longer rye plants resulted in increased average ear length. However, the differences were significant only for mono-cropped rye; an interaction of mixture type and cultivation system was significant, too. The greatest grain number in an ear resulted from the largest spikelet number. Significantly greater was the number of grains in ears from plots under rye cultivated in mixture with triticale.Pozycja Open Access Zróżnicowanie flory naczyniowej Doliny Strumienia Stróżewskiego w mezoregionie Równiny Pyrzycko-Stragardzkiej(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Bacieczko, Wanda; Klera, Magdalena; Kochanek-Felusiak, Agnieszka; Katedra Dendrologii i Kształtowania Terenów Zieleni Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Dendrologii i Kształtowania Terenów Zieleni Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Dendrologii i Kształtowania Terenów Zieleni Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThis paper presents the diversity of vascular flora resulting on varying habitat conditions and its correlation to different forms of anthropopressure in Stróżewska Stream valley (Pyrzyce Basin).

The content and weakening of gluten and falling number was estimated. It was noticed, that concentration of heavy metals did not exceed values admissible for consumption flour. Gluten quality for every grades of flour was good and did not decrease during the storage time. After longer storage time increase of falling number was observed.Pozycja Open Access Wpływ kadmu na kinetykę wzrostu roślin owsa(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Gregorczyk, Andrzej; Gawska, Agnieszka; Stolarska, Anna; Katedra Agronomii, Zakład Doświadczalnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Fizjologii Roślin, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Fizjologii Roślin, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe goal of the study was the assessment of the elongation growth of the naked oat var. 'Akt' to the contents of the toxic dosage of cadmium. Cadmium in toxically doses 20 and 100 mg per 1 kg of the soil and the control variant (0 mg Cd per 1 kg of the soil) were used in the pot experiment. The kinetics of plant elongation growth was analysed by means of a logistic function. The coefficients of logistic model have been estimated numerically by means of the Levenberg-Marquardt method. The applied dose of cadmium 20 mg · kg–1 of the soil did not significantly limited the elongation growth of the oak plants. The cadmium dose of 100 mg · kg–1 in the soil had an adverse influence on the growth as a result the stage of the maximum growth speed was about 10 days delayed in comparison to the control variant and the final height of plants was significantly limited.Pozycja Open Access Reakcja siewek pszenżyta ozimego na zróżnicowane natężenie oświetlenia i podwyższone stężenie CO2(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Brzóstowicz, Aleksander; Gregorczyk, Andrzej; Katedra Agronomii, Zakład Doświadczalnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie ul.

Two levels of photosynthetic photon flux density (PPFD): 400 i 800 Dmol · m–2 · s–1 were set as well as four levels of CO2 concentration: 400 (control), 800, 1200, 1600 Dmol · mol–1. Stimulating effect of higher lever of CO2 concentration on seedlings has been established (to control). Favorable impact of lighting intensity (PPFD) 800 Dmol · m–2 · s–1 and concentration of CO2 800 Dmol · mol–1 on biometric features of analyzed seedlings has been shown.
