    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Szczuko, Małgorzata; Krzemianowska, Ewa; Janda, Katarzyna; Wolska, Jolanta; Jamioł-Milc, Dominika; Department of Biochemistry and Human Nutrition, Pomeranian Medical University in Szczecin
    Recently there have been many studies on positive effect of honeys on various diseases, especially in treatment of cardiovascular diseases. Even though the majority of results suggest positive influence in the treatment of those diseases the authors of those research wanted to indicate other aspects, often negative, connected to the consumption of honey available at retail. The performed study relates to the adulteration of 35 natural honeys obtained from private apiaries and at retail. The honeys were subjected to the quality tests PN-88/A- 77626 on the presence of saccharose (Lane-Eynon’s method), starch, artificial acidic and basic dyes, water (refractometric method), total acidity and antioxidative activity (spectrophotometric method). Among the tested honeys more than 50% contained more than 10% of saccharose, and the relation between higher saccharose content and the presence of lower acidity in honey was determined, what will have unfavorable influence on antibacterial properties. Also lowered antioxidative activity of honeys was observed – within the range of 10.32–80.56 percent of inhibition of DPPH radicals and relatively high water content in 17% honeys, what will negatively affect the microbial stability of the product. The presence of starch and synthetic dyes in honey samples were not determined. It is postulated to maintain caution in nutrition honey with no approved quality of the chronically ill.

    Human chorionic gonadotropin (hCG) applied instead of first mating improves reproduction in mink (Neovison vison)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Seremak, Beata; Pławski, Kamil; Felska-Błaszczyk, Lidia; Lasota, Bogdan; Department of Biotechnology of Animal Reproduction and Environmental Hygiene West Pomeranian University of Technology, Szczecin; Department of Biotechnology of Animal Reproduction and Environmental Hygiene West Pomeranian University of Technology, Szczecin; Laboratory of Animal Anatomy, West Pomeranian University of Technology, Szczecin; Department of Biotechnology of Animal Reproduction and Environmental Hygiene West Pomeranian University of Technology, Szczecin
    The aim of the study was to determine how an administration of chorionic gonadotropin (hCG) in place of the first mating would affect breeding performance of female American mink (Neovison vison). The experiment was conducted in two consecutive breeding seasons on groups of females composed of one- and two-year old mink, similar in body weight, belonging to three colour morphs: Sapphire, Standard Brown (Wild), and Mahogany. The experimental group were females treated with an injection of 20 IU hCG instead of being subjected to the first mating. The females were first mated on day 8 after the treatment, repeated on the following day (scheme: 8 + 9). The control females were mated in a conventional way, three times (scheme: 1 + 8 + 9). Statistically significant differences were found in litter sizes (both numbers of born and live-born kits) in favour of the hormonally treated females. The Mahogany females, treated with hCG, produced larger litters in both studied seasons, whereas Standard Brown and Sapphire females – in the second year of the experiment. The results indicate a positive effect of hCG stimulation on the fertility of female mink and advocate its use in the breeding practice.

    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, Szczecin
    Eucomis 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.

    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, Szczecin
    The 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.

    (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, Szczecin
    The 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.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kondracki, Stanisław; Bombik, Elżbieta; Banaszewska, Dorota; Bednarczyk, Małgorzata; Łagowska, Katarzyna; Department of Reproduction and Animal Hygiene, Siedlce University of Natural Sciences and Humanities; Department of Reproduction and Animal Hygiene, Siedlce University of Natural Sciences and Humanities; Department of Breeding Methods and Poultry and Small Ruminant Breeding, Siedlce University of Natural Sciences and Humanities; Department of Reproduction and Animal Hygiene, Siedlce University of Natural Sciences and Humanities; Department of Breeding Methods and Poultry and Small Ruminant Breeding, Siedlce University of Natural Sciences and Humanities
    The study was aimed at analysing the possibility of using concentrate mixes produced for broiler DKA-S and turkey chicks IB-1, IB-2 for rearing the Common and Golden Pheasant. Diet analyses were conducted on 40 birds, including 20 Common and 20 Golden pheasants. The Common and Golden pheasants in both diet groups did not significantly differ in body weight. During the rearing period, the mean body weight of the Common pheasants fed with the IB concentrate was higher than the body weight of those fed with the DKA-S concentrate. After 4 weeks, the difference in the mean body weight already reached more than 67 g. After 8 weeks, the pheasants in both diet groups were similar in body weight, amounting to 616.78 g in the case of those fed with the IB concentrate and 608.14 g in the case of the birds receiving the DKA-S concentrate. The Golden pheasants fed with IB throughout the rearing period were heavier than those maintained on DKA-S. After 8 weeks, they reached the body weight of 401.40 g, i.e. they were 65.5 g heavier than the pheasants fed with DKA-S. The mean daily body weight gains of the Common and Golden pheasants were higher in the case of the IB concentrate. The birds fed both with IB and DKA-S featured a very fast growth rate between the 1st day and the 4th week of age. Between the 5th and 8th week the growth rate decelerated, ranging from 57.95% to 75.45%. Compound mixes destined for broiler chicks and turkeys can be effectively used for rearing pheasants. In comparison with DKA-S, the IB concentrate provides better results in rearing both Common and Golden pheasants.

    The aim of research was preliminary assessment the influence of effective microorganisms and fertilization manure on the yield, morphological traits, photosynthetic activity, water use efficiency of Japanese knotweed (Polygonum Cuspidatum Siebold & Zucc.) and on amount of selected minerals in soil. Field experiment was conducted in 2014 and 2015 in Experimental Station in Lipnik near Stargard Szczeciński (53o12’N; 14o27’E), Poland. Experimental factors were EM – effective microorganisms (preparation) and fertilization manure. The experiment was conducted in the totally random system. The experiment consisted of four objects, in four replication: 1 – control (without EM preparation and fertilization); 2 – EM preparation; 3 – fertilization granulated manure; 4 – EM preparation and fertilization granulated manure. Effective microorganisms and manure fertilization had no significant effect on the yield, the number of plants per plot, their height, and diameter of stems of Japanese knotweed. Plants fertilized with manure and EM preparation with manure had higher concentrations of studied macronutrients (magnesium, calcium, phosphorus) and microelements. Greater intensity of assimilation and transpiration was observed in plants grown in the control plots (without EM and manure). Plant grown on objects fertilized with manure as well as EM preparation and manure- -treated better utilized water during its shortages (in 2015 year).

    The 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.

    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, Szczecin
    This 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.

    Preliminary research on evaluation of sperm morphometry and chromatin structure in the semen of silver fox (Vulpes vulpes)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Andraszek, Katarzyna; Szeleszczuk, Olga; Niedbała, Piotr; Kuchta-Gładysz, Marta; Department of Animal Genetics and Horse Breeding, Institute of Bioengineering and Animal Breeding Siedlce University of Natural Sciences and Humanities; Department of Animal Anatomy, Institute of Veterinary Science University of Agriculture in Krakow; Department of Swine and Small Ruminant Breeding, Institute of Animal Science University of Agriculture in Krakow; Department of Animal Anatomy, Institute of Veterinary Science University of Agriculture in Krakow
    Semen analysis is a way to predict male fertility. The quality of sperm morphology evaluation depends on the diligence put in the preparation of smears, their fixation and cell staining, since these may affect the morphometry of the head and the entire sperm alike. The aim of the study was a detailed morphometric analysis and chromatin structure evaluation in the sperm cells of the silver fox (Vulpes vulpes). The material involved the sperm of year-old captive silver foxes. The slides were stained using one of the following dyes: aniline blue (AB), chromomycin (CMA3), and acridine orange (AO). The staining revealed prevailing sperm with normal histone retention. The measurements resulted in the following mean values of the fox sperm morphometric parameters: head length and width: 6.59 μm and 4.39 μm, respectively, head perimeter: 17.98 μm, head area: 21.69 μm2, acrosome area: 11.2 μm2, acrosome coverage: 51.69%, mid-piece length: 12.84 μm, mid-piece coverage: 19.72%, tail length: 65.11 μm, sperm length: 71.70 μm, head ellipticity index: 1.51, head elongation: 0.2, head roughness: 0.84, and head regularity: 1.05. According to the literature on differential sperm staining for morphological evaluation purposes, the lack of established standards and the use of a variety of dyeing techniques appear as a current issue.
