Pozycja Open Access Quality of bread made from rye grown wiyh conventional and ecological methods(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Wianecki, Marek; Iwański, Robert; Stankowski, Sławomir; Tokarczyk, Grzegorz; Felisiak, Katarzyna; Department of Food Science and Technology, West Pomeranian University of Technology, Szczecin; Department of Food Science and Technology, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Food Science and Technology, West Pomeranian University of Technology, Szczecin; Department of Food Science and Technology, West Pomeranian University of Technology, SzczecinThere were checked the baking proprieties of six rye cultivars coming from conventional and ecological tillages. Bread made from rye grown with conventional method characterized with higher volume and imperceptibly lower baking loss. The way of tillage had no essential influence on porosity. Bread made from cultivar Conduct grown with ecological way received the highest notes in the sensory assessment (31.5 points). The addition of 1-moll lactic acid to the dough enlarged bread volume, bread porosity and the total baking loss, not influencing on the sensory assessment of breads. In dependence of analyzed feature of texture the factor of changeability (the way of tillage, cultivar and the method of baking) influenced on the reological properties of breads from rye flour in different degree. The hardness, gumminess and chewiness of crumb depended on way of tillage, then on cultivar as well as the addition of souring agent. The cohesiveness of crumb depended on the way of tillage mainly. However there was affirmed no influence of the studied variables on bread springiness.Pozycja Open Access Reakcja nowych odmian pszenżyta ozimego na czynniki agrotechniczne(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Jaśkiewicz, Bogusława; Zakład Uprawy Roślin Zbożowych, Instytut Uprawy Nawożenia i Gleboznawstwa PIBIn the 2005–2008 in IUNG-PIB in Pulawy experiments were conducted with purpose to determine requirements of some new winter triticale varieties to main agrotechnical factors: sowing term, sowing density and nitrogen fertisation. The investigated forms showed different requirements in regard to all the experimental factors. Differences were shown in response of the varieties to the factors and grouping of the triticale objects was performed.Pozycja Open Access Wpływ regulatora wzrostu i rozwoju roślin trineksapak etylu oraz jego mieszaniny z chlorkiem chloromekwatu na cechy struktury plonu roślin pszenżyta ozimego w zależności od poziomu nawożenia azotowego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Matysiak, Kinga; Kierzek, Roman; Krawczyk, Roman; Instytut Ochrony Roślin – Państwowy Instytut Badawczy w Poznaniu; Instytut Ochrony Roślin – Państwowy Instytut Badawczy w Poznaniu; Instytut Ochrony Roślin – Państwowy Instytut Badawczy w PoznaniuTrials were conducted in the Institute of Plant Protection in Poznan. Aim of the experiments was evaluation of trinexapac-ethyl used on different nitrogen fertilisation level. The objectives of the experiment was winter triticale cv. Fidelio. Trineksapak ethyl (TE) was applied in two doses 75 g a.i. . ha-1 and 125 g a.i. . ha-1 and nitrogen fertilisation was applied in 0 kg N . ha-1, 80 kg N . ha-1 and 160 (80 + 80) kg N . ha-1. Evaluation contains: weight of 1000 grains, number of grains in ear, protein content and yield. Results confirm that yield structure components and protein content of winter triticale are influenced by retardants and nitrogen fertilisation interaction. Changes in yield structure components and protein content in winter triticale were highly dependent on weather conditions during the vegetation seasons.Pozycja Open Access Wpływ regulatora wzrostu i rozwoju roślin trineksapak etylu oraz jego mieszaniny z chlorkiem chloromekwatu na dynamikę wzrostu i cechy morfologiczne roślin pszenżyta ozimego w zależności od poziomu nawożenia azotowego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Matysiak, Kinga; Kaczmarek, Sylwia; Instytut Ochrony Roślin – Państwowy Instytut Badawczy w Poznaniu; Instytut Ochrony Roślin – Państwowy Instytut Badawczy w PoznaniuTrials were conducted in the Institute of Plant Protection in Poznan. Aim of the experiments was evaluation of trinexapac-ethyl used on different nitrogen fertilization level. The objectives of the experiment was winter triticale cv. Fidelio. Trineksapak ethyl (TE) was applied in alone in two doses 75 g a.i. . ha-1 and 125 g a.i. . ha-1 and in a mixture with chlorocholine chloride (CCC) in dose 50 g a.i. . ha-1 (TE) + 675 g a.i. . ha-1 (CCC) on three nitrogen fertilisation levels. Nitrogen fertilisation was applied in 0 kg N . ha-1, 80 kg N . ha-1 and 160 (80 + 80) kg N . ha-1. Evaluation contains such measurements as stem length, ear length, and internode length, stem diameter, the 3rd internode diameter and chlorophyll content. Results confirm that influence of trinexapac-ethyl on winter triticale is changing depending on nitrogen fertilisation dose. Interaction between experimental factors was strongly determined by meteorological conditions during the vegetation season.Pozycja Open Access Wpływ stężenia soli na proces marynowania świeżego śledzia bałtyckiego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Szymczak, Mariusz; Kołakowski, Edward; Tokarczyk, Grzegorz; Felisiak, Katarzyna; Krzywiński, Tomasz; Katedra Technologii Żywności, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Technologii Żywności, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Technologii Żywności, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Technologii Żywności, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Technologii Żywności, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieInfluence of salt concentration on Baltic herring carcasses was studied. There was shown, that increase of salt concentration caused significantly lower value of pH, water holding capacity and consistence of non-peptide nitrogen, but meat hardness and red color parameter increased. The increase of salt concentration caused the strongest blocking of peptides (PHB(R)) then tyrosine (PHB(A)) growth. The sensory evaluation values show that the best semi-marinades obtained during marinating in brine contained 5, 7 and 9% of NaCl and 4.5% of acetic acids.Pozycja Open Access Występowanie suszy atmosferycznej w okresach rozwojowych pszenżyta jarego w północno-zachodniej Polsce(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Kalbarczyk, Eliza; Zakład Meteorologii i Klimatologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe aim of the study was to determine intensity and frequency of occurrence of atmospheric drought during the development periods of spring triticale in north western Poland. In order to realize the task, the results of agrophenological observations of spring triticale pattern were used. The observations were carried out at 8 COBORU (Research Center for Cultivar Testing) experimental stations located in north western Poland over 1984–2004. The experimental material consisted also of the precipitation totals gathered at 12 IMGW (Institute of Meteorology and Water Management) stations during the years 1965–2004. The drought periods were identified on the basis of the standardized precipitation index SPI. It was stated that the largest number of dry periods in north western Poland were observed in the central part of Pomeranian Lakeland and in the Szczecin Lowland and the smallest – in the central part of the Coast. Spring triticale was threatened most by the occurrence of drought during the periods of emergence-tillering and heading-wax maturity. Very strong and extremely strong droughts occurred more frequently in the period of heading-wax maturity and sowing-emergence, least rarely – in the period of shooting-heading. According to the SPI index, periods of extreme intensity of drought occurred most frequently in the south western part of the investigated area, whereas they were not a threat in its eastern part and in the vicinity of Szczecin. There was no statistically confirmed increase in frequency of occurrence of atmospheric drought in north western Poland over the years of studies.
