Pozycja Open Access Dobowa zmienność temperatury w profilu gleby porośniętej w stacji meteorologicznej w Ostoi(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Michalska, Bożena; Nidzgorska-Lencewicz, Jadwiga; Zakład Meteorologii i Klimatologii, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Meteorologii i Klimatologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe material used in the study is based on the results of the measurements of soil temperature carried out from 1 December 2008 to 30 November 2009 in the Ostoja meteorological station located in the suburbs of Szczecin. The analysis included hourly results of automatic measurements made at the standard depths of: 5, 10, 20 and 50 cm on the soil overgrown with lawn, in the real zonal time. Monthly, seasonal and annual mean temperatures of soil in individual hours of the day were calculated. In order to grasp temporal variability during the day (24hours), the hourly distribution of mean and extreme values and the standard deviation in four seasons of the year were illustrated in the diagram. Monthly variability of the temperature of soil in the profile of 5–50 cm during 24 hours was shown in a form of thermoizoplets. The influence of snow cover and atmospheric precipitation on the vertical distribution of temperature in soil in selected days was evaluated.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 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 Ocena warunków biotermicznych w Polsce środkowozachodniej na podstawie temperatury odczuwalnej (STI)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2010) Mąkosza, Agnieszka; Michalska, Bożena; Instytut Technologiczno-Przyrodniczy w Falentach, Zachodniopomorski Ośrodek Badawczy w Szczecinie; Zakład Meteorologii i Klimatologii, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn studies of the bio-thermal conditions, index of sensitive temperature STI (Subjective Temperature Index) was applied. It was based on the analysis of human heat balance – Menex 2005 model (from 12 UTC values of meteorological data). Data in the period of 1971–2006 was used, including: air temperature, relative humidity of air, clouds and wind speed from 7 stations IMGW Słubice, Gorzów Wielkopolski, Toruń, Poznań, Koło, Zielona Góra, Leszno. The sensation of cool was the most often occurring – exceeding 40% of days per year in the all stations, and cold sensation ranged depending on location from 21 to 26% of days from October to April. The sensation of warm occurred in 30% of days in every months from May to September. Biothermal comfort was noticed from February and was appeared even in November but the highest frequency of occurrence was in May and August. Hot sensation ranged from 5.6 to 7%, whereas very hot from 0.5 to 3% of days per year. In the period of 1971–2006 increase number of days causing hot sensation discomfort (1.7 day per 10 years) and decrease of days causing cold sensation discomfort (4.3 days per 10 years) was noticed. Number of comfortable days with the least load organism, shows a positive trend (2.6 day / 10 years).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 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.
