Pozycja Open Access Assessment of the progress of integrated pest management products implementation into agricultural production space(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Zatoń, Kinga; Błaszak, Magdalena; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, SzczecinThe study was aimed at assessing the progress of integrated pest management (IPM) implementation into agricultural practices. Assessment of farmers’ attitude to the new EU policy to reduce the use of insecticides as well as evaluating the real possibilities of biological methods use for plant protection was analyzed. Almost 60% of farmers whose farms were conducted in a conventional system declared the use of pesticides prophylactically. Farmers conducted intensive agriculture do not know the principles of IPM (prohibition of pesticides abuse). However, it is possible that these farmers know the restrictions introduced in 2014 without accepting them. It has been observed that in the group of farmers declaring the knowledge upon principles of IPM, the proportion of respondents aware of pesticides ecotoxicity increases. Therefore, a continuous education of farmers seems justified, but at simultaneous expanding the range of biological products and support mechanisms for farmers, who quit the intensive use of chemicals.Pozycja Open Access Metabolic potential of bacteria strains isolated from poultry industry waste(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Wrońska, Ilona; Cybulska, Krystyna; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, SzczecinMicrobial composition of poultry industry wastes was very diverse. They are inhabited by microorganisms that use organic substance to their growth. An appropriate composition of microorganisms is very important in the organic matter decomposition rate. Therefore, microorganisms that contribute to decomposition of several compounds are quite desired. The study dealt with the evaluation of metabolic activity of bacterial strains towards lipids, protein, and starch. The strains were isolated from the poultry waste environment. Metabolic potential of bacterial strains was determined based on the activity index and taking into account the hydrolysis zone diameter and colony diameter. Bacterial strains to a different degree decomposed the organic compounds. Their metabolic activity and direction towards substrates depended on the type of isolated bacterial strains.Pozycja Open Access Influence of distillation apparatus and distillation time on the yield and chemical composition of winter savory essential oil(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Wesołowska, Aneta; Grzeszczuk, Monika; Jadczak, Dorota; Department of Organic and Physical Chemistry, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinThe aim of the studies conducted in 2014–2015 was to determine the influence of distillation apparatus as well as distillation time on the yield and chemical composition of winter savory (Satureja montana L.) essential oil. Isolation of the essential oil from S. montana herb, collected during flowering period, was carried out using two different distillation apparatuses: Deryng and Clevenger. Moreover, different distillation times (2, 3 and 4 hours) were also applied. The obtained essential oils were analyzed by gas chromatography-mass spectrometry (GC-MS). GC-MS analysis resulted in the identification of 47 compounds in the essential oils obtained in Deryng and Clevenger apparatus, respectively. Carvacrol (54.44–68.53%) was the major constituent of all S. montana oil samples. Other important compounds were: γ-terpinene (5.21–8.67%), p-cymene (4.40–9.53%), α-terpinene (1.20–2.04%) and β-caryophyllene (4.58–5.77%). On the basis of the obtained data it was proved that the time of distillation of S. montana herb in Deryng apparatus had no significant effect on its content. However, the amount of volatile oil obtained in Clevenger apparatus was significantly influenced by distillation time. Moreover, there was no significant effect of the distillation time on the amount of the main essential oil constituents obtained with both types of apparatuses. However, there was a significant interaction found between the constituent and the distillation time.Pozycja Open Access Response of soil peroxidases to 1-alkyl-3-methylimidazolium ionic liquids with tetrafluoroborate anion(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Telesiński, Arkadiusz; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, SzczecinThe aim of study was to determine effect of 1-alkyl-3-methylimidazolium ionic liquids with tetradluoroborate anion on activity of soil peroxidases. The experiment was carried out in laboratory conditions with samples of loamy sand (Corg 8.71 g · kg–1, pHKCl 6.36), sandy loam (Corg 10.92 g · kg–1, pHKCl 6.81) and sandy clay loam (Corg 33.81 g · kg–1, pHKCl 7.13). Samples were sieved through a 2-mm mesh, and then three ionic liquids: 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM][BF4], 1-bhexyl-3-methylimidazolium tetrafluoroborate [HMIM][BF4], and 1-octyl-3-methylimidazolium tetrafluoroborate [OMIM][BF4] at the dosages of 0, 10, 100, and 1000 mg · kg–1 were added to soil. Activity of peroxidases was measured spectrophotometrically on days 1, 3, 7, 14, 28, 56 and 112. Application of different dosages of all ILs caused mainly significant changes in activity of peroxidases. Changes in activity of peroxidases depended on the dosage of ionic liquids, incubation time, and soil properties. The effect of ILs on activity of peroxidases increased not only with an increasing dosage, but also with elongation of alkyl substituents in the cation. The highest impact of ILs on activity of peroxidases was observed in loamy sand.Pozycja Open Access Dart markers linked with genes controlling restoration of male fertility in hybrid rye cultivars with improved pollen shedding(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Stojałowski, Stefan; Hanek, Monika; Orłowska, Marta Orłowska; Sobczyk, Martyna; 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 Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, SzczecinIn this study, we aimed to apply a high-throughput genotyping method to map genes important for the restoration of male fertility in a hybrid cultivar of rye containing the Pampa sterilizing cytoplasm. The diversity arrays technology (DArT) was used to analyse 48 individuals of the F2 population obtained by crossing the male-sterile S305P line with a plant randomly chosen in the Gonello F1 cultivar. In addition to DArT markers, a set of previously published PCR-based markers was also used for genotyping. In total, more than 3300 markers were used in this study. A mapping analysis allowed a construction of seven linkage groups containing 763 markers covering a total distance of approximately 520 cM. Eighty molecular markers were applied to identify genomic regions important for the male fertility restoration. Their distribution indicated the presence of a major and minor restorer genes on chromosomes 4RL and 1R, respectively. These results were consistent with previous reports on the genetic control of the male fertility in the CMS-Pampa. Moreover, new molecular markers located in chromosomal regions significantly associated with the restoration of male fertility were found as well, including PCR-based markers converted from the DArT markers.Pozycja Open Access Development of fermented beverages based on acid whey(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Skryplonek, Katarzyna; Jasińska, Małgorzata; Department of Dairy Technology and Food Storage, West Pomeranian University of Technology, Szczecin; Department of Dairy Technology and Food Storage, West Pomeranian University of Technology, SzczecinAcid whey is a valuable raw material obtained during acid-coagulated cheese and acid casein production. Nowadays whey processing techniques are well developed, however the utilization of acid whey, due to low pH, still remains a challenge especially for small dairy plants. The aim of the study was to design and evaluate the fermented beverages based on acid whey containing yogurt bacteria starter cultures. In order to enrich casein content and obtain product with quality characteristics similar to fermented milk drinks, whey was combined with milk, unsweetened condensed milk or skimmed milk powder. Moreover, the beverages were supplemented with prebiotics: inulin and oligofructose and whey protein concentrates. The evaluation of the beverages included acidity measurement and sensorial analysis. Moreover the conditions of whey pasteurization were evaluated. According to the results, the best raw materials and additives were selected. It was stated, that to obtain the product with good sensory characteristics, the addition of milk must amount minimum 50%. The results allowed to invent several kinds of fermented beverages with desirable properties. The most appropriate conditions of whey heat treatment was pasteurization at the temperature of 72°C for 10 minutes. The obtained results indicated that acid whey can be considered as a raw material for the production of fermented beverages with acceptable sensory quality. The practical impact of the work comes from the aspect, that it presents the new method of direct utilization of acid whey and it may be a new, attractive alternative for dairy industry.Pozycja Open Access Effects of deficiency and excess of phosphorus and potassium in hydroponics on selected physiological and biometrical traits of basket willow (Salix viminalis L.)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Rokosa, Marta; Mikiciuk, Małgorzata; Wróbel, Jacek; Łowicka, Milena; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, SzczecinBasket willow (Salix viminalis L.) is one of so-called energy crops, which are used to renewable energy source. In conducted research rated effects of deficiency and excess of phosphorus and potassium on selected physiological traits of two willow genotypes: ‘Bjor’ and ‘Tora’ in hydroponics. The purpose of the study was to select genotype which is more resistant to disturbed trophic relationships in the environment. To full Hoagland medium (control sample) added 20% and 40% phosphorus and potassium and also reduced the content of these elements by 20% and 40%. A number of shoots produced by plants, the length the shoots, yield of the fresh and dry mass of the aboveground and root systems and water balance of both examined willows were determined. The results indicated that the ‘Tora’ and ‘Bjor’ are similarly resistant to variable nutritional conditions by phosphorus and potassium.Pozycja Open Access Dependencies between prl gene polymorphism and production progress in polish holstein-friesian black-and-white cows(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Pytlewski, Jarosław; Antkowiak, Ireneusz R.; Stanisławski, Daniel; Czerniawska-Piątkowska, Ewa; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences; Computer Lab, Poznań University of Life Sciences; Department of Ruminant Science, West Pomeranian University of Technology, SzczecinThe aim of this study was to analyse dependencies between PRL gene polymorphism within exon 4 of bovine chromosome 23 (locus g.8398G>A), and the level of production progress in milk yield, yields of milk fat and milk protein in Polish Holstein-Friesian Black-and- -White cows. Results of this study indicate dependencies between genotype at locus g.8398G>A of the PRL gene and production progress in terms of milk yield as well as the yields of milk fat and milk protein.

The most sensitive to lead exposure were wheat, radish ‘Carmen’, alfalfa, sunflower, tomato.Pozycja Open Access Fungal contamination in poultry waste during the industrial processing(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Oraibi, Sanaa Mahdi; Cybulska, Krystyna; Department of Chemistry, Microbiology and Biotechnology of Environment, West Pomeranian University of Technology, Szczecin; Department of Chemistry, Microbiology and Biotechnology of Environment, West Pomeranian University of Technology, SzczecinThe poultry industry produces large amounts of waste that include solid waste and waste water. Although, numerous studies have been conducted on microbial associates with various stages related to poultry and meat products processing. Only a few studies have been reported on fungal exists of poultry wastes. The aim of this study investigation of fungi associated with different poultry wastes. The sample of poultry wastes included feathers, slime, biological sludge and compost. The samples were taken at various times in peroid from 2015–2016 from different poultry slaughter houses. Isolation of fungi was performed by serial dilution and plating methods on Rose Bengal Agar (RBA), medium supplemented with antibiotic. Identification of fungi was carried out by microscopic and genetic analysis 18S ribosomal RNA gene. The number of fungi (cfu · g–1 d.m.) were isolated from chicken and goose feathers 103–104, from duck and turkey feathers even 106–107, compost 103–105, slime – 104 and biological sludge – 104–106. From the overall analysis, the dependence between the number of fungi and various type of samples and the season of taking the samples were found and type of poultry slaughter houses.Pozycja Open Access Antioxidant enzymes activity and lipid peroxidation in serum, breast and leg muscles of broiler chickens reared in two different systems and exposed to elevated air temperature(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Muchacka, Renata; Greń, Agnieszka; Kapusta, Edyta; Skomorucha, Iwona; Sosnówka-Czajka, Ewa; Department of Animal Physiology and Toxicology, Pedagogical University of Cracow; Department of Animal Physiology and Toxicology, Pedagogical University of Cracow; Department of Technology, Ecology and Economics of Animal Production, National Research Institute of Animal Production, Balice, n. Krakow; Department of Technology, Ecology and Economics of Animal Production, National Research Institute of Animal Production, Balice, n. Krakow; Department of Animal Physiology and Toxicology, Pedagogical University of CracowThe aim of the study was to investigate possible oxidative damage in serum, breast and leg muscles in broiler chickens Ross 308 reared in two housing systems and exposed to high summer air temperature. 400 broiler chickens were divided into two groups (200 birde per group): I – birds kept on litter in an indoor system, II – chickens kept on litter with access to green paddocks. Birds were fed ad libitum standard diets based on concentrates. Throughout the study, birds had free access to water. Both groups were managed under uniform environmental (air humidity and temperature, lighting programme) and feeding conditions. In the 6th week of rearing, during high outdoor temperatures, antioxidant enzymes activity (CAT, SOD, GPx), glutathione (GSH) and malondialdehyde (MDA) concentrations in serum, breast and leg muscles tissues were investigated. In addition, blood and tissue samples were collected 1 day before high summer outdoor temperatures. The results showed that elevated air temperature initiates oxidative stress in broiler chickens, regardless of rearing system, but broiler chickens using green paddocks were characterized by a more stable antioxidant system. High air temperatures initiate lipid peroxidation as indicated by increased MDA levels, however leg muscles are more sensitive to the effect of oxidative stress than breast muscles.Pozycja Open Access Daily activity of polish holstein-friesian cows depending on variable housing conditions during lactation(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Mróz, Piotr; Wójcik, Piotr; Pankowski, Mateusz; Faculty of Animal Science, Warsaw University of Life Sciences; Department of Animal Genetics and Breeding, National Research Institute of Animal Production, Balice; Alta Polska Ltd., ŁowiczThe aim of the study was to analyse the activity of Polish Holstein-Friesian cows depending on variable housing conditions during lactation, associated with short-term (30-day) reduction in the living area. The study used two groups of cows (25 animals per group) housed in sections with or without an outdoor area and subjected to temporary (30-day) crowding as well as one group of cows subjected to decreasing stocking density. All animals were fitted with pedometers on the hind legs, which recorded data on activity (steps/hour), resting frequency (times per day), resting bout duration (minutes), and total resting time (minutes). Activity analysis of the groups performed before the change in stocking density showed that in the group of cows without outdoor access, fourth lactation cows (175.59 steps/h) and primiparous cows were the most active (147.09 steps/h). Primiparous cows rested most frequently (14.14) and showed longest total resting time (588.73 min). In the group with outdoor access, significantly highest activity was shown by primiparous cows (132.18 steps/h) and lowest activity by fourth lactation cows (108.92 steps/h). Fourth lactation cows were also characterized by lowest resting frequency (8.41) and lowest total resting time (525.16 min), as well as longest resting bout (74.91 min). Following the first increase in stocking density, the group of cows without outdoor access showed very high activity (133.65 steps/h), and the cows with outdoor access reduced their activity. The next increase in stocking density caused the confined cows to increase their activity, which was associated with increasing stress, while the group of cows with outdoor access did not respond with higher activity but the duration of resting bout increased (61.16 min) and its frequency decreased. As a result, total resting time was shorter than in the group without outdoor access. In the group without outdoor access, rests were less frequent but longer (59.91 min), which could be due to the difficulty finding a place to rest. In all the study groups, total resting time decreased to an unprecedented time of less than 490 min.Pozycja Open Access Effects of 2-hydroxybenzoic acid on the efficiency of the photosynthetic apparatus of basket willow (Salix viminalis L.) plant growing under conditions of salt stress(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Mikiciuk, Małgorzata; Malinowska, Katarzyna; Wróbel, Jacek; Ptak, Piotr; Studziński, Mateusz; Rokosa, Marta; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, SzczecinThe study conducted in 2016 at the Department of Plant Physiology and Biochemistry at the West Pomeranian University of Technology in Szczecin was to evaluate the effect of exogenous application of 2-hydroxybenzoic acid (salicylic acid) on the efficiency of the photosynthetic apparatus of basket willow growing under conditions of elevated salt concentration. The first experimental factor was the concentration of sodium chloride (control – complete Hoagland medium, 3.0 g NaCl ∙ dm–3) and second was the concentration of 3-hydroxybenzoic acid (control – complete Hoagland medium, 138 mg ∙ dm–3). The Tora clone tolerated a short period of exposure to the NaCl concentration, as evidenced by high values of Performance Index (PI), Area, and maximum, potential efficiency of photochemical reaction in PS II determined after darkening adaptation, after reduction of acceptors in PS II (FV/FM). Longer plant exposure to salinity resulted in a decrease value of TFM parameter in the Tora clone, and PI and FV/FM in Bjor clone. The application of 2-hydroxybenzoic acid had a varied effect on chlorophyll "a" fluorescence induction parameters of basket willow growing under salt stress conditions. The use of 2-hydroxybenzoic acid increased the parameters such as chlorophyll fluorescence growth time from the beginning of the measurement to the maximum (TFM) and FV/FM in the Bjor clone with prolonged exposure to higher NaCl concentrations. For the Tora clone, the PI value decreased.Pozycja Open Access Hemolymph pH as a marker of pesticide exposition(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Maliszewska, Justyna; Wyszkowska, Joanna; Tęgowska, Eugenia; Department of Animal Toxicology, Nicolaus Copernicus University, Toruń; Department of Biophysics, Nicolaus Copernicus University, Toruń; Department of Animal Toxicology, Nicolaus Copernicus University, ToruńChanges in blood biochemical parameters reflects disorders in the whole body after exposition to contaminants. Insect hemolymph circulates in direct contact with the animals’s tissues, therefore every disruption that appears in the body is reflected in change of hemolymph parameters. The aim of this study was to assess the potential of hemolymph pH as the marker of insecticide intoxication. Experiments were performed on mealworms Tenebrio molitor L., intoxicated with insecticides’ characterized by different mechanisms of insecticidal action – pyrethroid, oxadiazine, neonicotinoid and organophospate in different ambient temperatures (15°C, 25°C and 35°C). Hemolymph pH and insects’ mortality after intoxication was assessed after three days from insecticides application. The results obtained showed a correlation between mortality and pH of the hemolymph. Intoxication with insecticides resulted in pH decrease: the greater decline was determined, the higher mortality was observed. The results indicate that hemolymph pH may be used as a marker of organism exposition to xenobiotics.Pozycja Open Access Physiological reaction of basket willow (Salix viminalis L.) to zinc excess(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Malinowska, Katarzyna; Wróbel, Jacek; Mikiciuk, Małgorzata; Studziński, Mateusz; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, SzczecinThe influence of zinc salt, in a concentration range of 50 to 650 mg · dm–3, on the physiological response of basket willow was studied on Bjor, Tora and Jorr varieties which were grown in hydroponics. Content of chloroplast pigments, relative water content (RWC), water saturation deficit (WSD), intensity of assimilation and transpiration, stomatal conductance, photosynthetic rate of water use efficiency (WUE) and instantaneous photosynthetic rate of water use (WUEI) were determined in leaves. It was observed that the decrease in concentration of tested physiological parameters correlated with the increase of zinc salt doses in the medium. The assimilation and transpiration of basket willow were significantly limited by stomata. The addition of zinc salt to the medium increased water saturation deficit in leaves of all three Salix viminalis verities.Pozycja Open Access The growth of soil fungi Penicillium in the presence of N-(2-pyridylamino) methylenebisphosphonate as an alternative source of nutrients(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Krzyśko-Łupicka, Teresa; Kręcidło, Łukasz; Kręcidło, Magdalena; Independent Department of Biotechnology and Molecular Biology, University of Opole; Independent Department of Biotechnology and Molecular Biology, University of Opole; Independent Department of Biotechnology and Molecular Biology, University of OpoleN-(2-pyridylamino)methylenobisphosphonic acid exhibits high herbicidal capability. In this we would like to examine its interaction with soil microorganisms. The aim of this study was to evaluate the ability of Penicillium strains to grow in the presence of 1 mM N-(2- -pyridylamino)methylenobisphosphonic acid as an alternative source of phosphorus, nitrogen or carbon. The pure fungal cultures have been grown in Czapek medium or modificated medium, at 25°C for 1–4 weeks. The growth of fungi in full mineral pH 5.6 and pH 4.0 media was considered as controls, whereas the growth of fungi in medium without nutriment (carbon, nitrogen, phosphorus, nitrogen and phosphorus) was an absolute control. In our studies we determined: the kinetics of mycelial growth, fungi morphology, degree of degradation of N-(2-pyridylamino)methylenobisphosphonic acid by spectrophotometric UV-VIS and changes of media pH. Tested fungi did not use a N-(2-pyridylamino)methylenobisphosphonic acid as an alternative source nutrition. In each of the modified growth medium, inhibition of mycelial growth was observed. However, no changes of the concentration of studied acid in medium was observed. Simultaneously, we noticed phenotypic changes of the fungi what indicate that the metabolic disturbances in the presence of acid.Pozycja Open Access The effects nano-silver on contamination of spring barley ‘Eunova’ in vitro(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Krupa-Małkiewicz, Marcelina; Ochmian, Ireneusz; Mijowska, Kamila; Cendrowski, Krzysztof; Department of Plant Genetics, Breeding and Biotechnology, West Pomerania University of Technology, Szczecin; Department of Horticulture, West Pomerania University of Technology, Szczecin,; Department of Horticulture, West Pomerania University of Technology, Szczecin,; Nanomaterials Physicochemistry Department, West Pomeranian University of Technology, SzczecinOne of the available methods to control in vitro contaminations is nano-silver. Nanosilver is a non-toxic material which shows high capabilities in eliminating microorganisms, e.g., bacteria, viruses or fungus. The aim of the current study was to evaluate the potential of nano- -silver particles on decontamination, growth parameters (plant length, root length) and leaves colour of spring barley ‘Eunova’ in in vitro culture. Plant material consisted of embryos of barley which were placed on MS medium supplemented with 4.0 and 6.0 0 mg ・ dm–3 of nano-silver or submerged in 50 or 100 0 mg ・ dm–3 of nano-silver for 2 or 4 h. The control consisted of embryos treated with 70% alcohol. After 28 days it was observed, that both of the disinfection methods, operating time as well as concentrations of nano-silver, had an influence on a number of contaminations, shoot and root length and colour of the barley leaves. The smallest efficiency (100% contaminations) was found after embryos submerged in 50 mg dm-3 of nano-silver for 2 h. On the other hand, the best disinfection efficiency (0% infection) was obtained when 4.0 0 mg ・ dm–3 nano-silver was added to MS medium. Barley embryos soaked in 100 mg ・ dm–3 in nano-silver solution and grown on MS media with addition of nano-silver independent of their concentration showed similar disinfection effectiveness.Pozycja Open Access Analysis of the content of macro- and microelements in the leaves of sea buckthorn (Hippophaë rhamnoides L.)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Jaroszewska, Anna; Biel, Wioletta; Gibczyńska, Marzena; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, SzczecinSea buckthorn is used in the world primarily for its high nutritional value and unique healing properties. It is a plant with a small climate and soil requirements. The study was conducted to determine changes mineral compounds in leaves of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), depending on the substrate type and the passage of time and assessment of the potential for sea buckthorn growth on saline and degraded soil. The determined the amounts of nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, sodium, molybdenum, chromium, lead, and cadmium. Shrubs of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), of which leaves were collected in June 2015, were located in four sites in Szczecin. The soils, on which sea buckthorn bushes grow are alkaline. The different sites of the growing shrubs of sea buckthorn (Hippophae rhamnoides L.) and the applied fertilization resulted in the differentiation of P, K, Ca, and Mg in leaves of the plant, but no change in N content was observed. Leaf samples collected a year earlier contained more N and P and less Ca and Mg. Leaves of sea buckthorn growing on the banks of the Odra river contained over ten times more Na, twice as much Fe, three times as much Mn as leaves of shrubs growing elsewhere. There was no difference in the amount of Mn in the leaves over the years, while those collected a year earlier contained more Fe. No presence of Mo, Pb, Cr and Cd was recorded in the leaves of sea buckthorn (Hippophae rhamnoides L.). Uptake of large amounts of Na, Ca, and Mg by sea buckthorn indicates the possibility of its growing on saline and degraded soils and the passage of time.Pozycja Open Access Biological control of Fusarium culmorum isolated from the cultivation of white asparagus by Pseudomonas fluorescens(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Grata, Katarzyna; Department of Biotechnology and Molecular Biology, Opole UniversityAssessment of the effect of Pseudomonas fluorescens I-4 (Ps I-4) on the Fusarium culmorum isolated from the cultivation of white asparagus was the aim of the conducted research. Fusarium culmorum and other fungi were isolated on the PDA and asparagus media. Among the isolates obtained from soil, F. oxysporum and F. culmorum were the most dominant pathogens. The biological properties of non-volatile and volatile compounds of Ps I-4 were assessed with the culture-plate method on the PDA and Czapek media. The fungistatic activity of bacterium was determined against the growth rate index, the spore germination index and the rate of mycelial growth and spore inhibition. The results show differences in the fungistatic activity of P. fluorescens, dependent on the age and density of the bacterial culture, the type of medium and the presence of volatile or non-volatile metabolites. The obtained results prove, that Ps I-4 show a higher activity against the fungal spores germination (82–94% inhibition) than on mycelium growth of F. culmorum. The highest inhibition of the linear growth of mycelium has been observed for the supernatants obtained from a 6-hour culture (64–76% inhibition). P. fluorescens I-4 showed positive reactions for the production of HCN, siderophores, protease, lipase and phosphate solubilisation.
