Opis:
The aim of this study was verification whether an 8-week-long swimming exercise training would induce adaptive changes in body weight in rats and whether possible changes would depend on aquatic environment temperature and animal sex. The exercisetrained groups swam 4 minutes a day, five days a week during eight week of housing. Exercise was performed by swimming in glass tanks containing tap water maintained according to group at 5 ±2°C (cold group) and 36 ±2°C (thermal neutral group). Before and after each week of the experiment, rats were weighed. When comparing the nature of changes in the body weight of rats exposed to swimming exercise training in cold water, attention should be paid to their dependence on sex. There were statistically significant changes in the nature of changes in body weight between male rats and female rats of the cold group (5°C) as early as experimental week 2 until the end of the experiment (p < 0.001). Interestingly, the females exposed to swimming exercise training at 5°C were the only group in which an increase in body weight occurred during experimental week 8 in relation to baseline values.

Opis:
The quality of 39 Japanese larch stands, mainly in north-western Poland, was characterized. On the basis of the presented results it can be concluded that properly managed forest stands of Japanese larch can compete in trees quality with stands of native larches. The alien species is more susceptible to a lower stand density and exposure to strong winds. This is no correlation between forest stand quality and growth dynamics.

Opis:
Under a scanning microscope, leaves from tissue cultures (after 8 weeks in vitro culturing), from 1 year old regenerants and from the 100 years old donor tree were studied. More abnormalities were observed in the tissue culture compared to regenerant and donor. During tissue culture transfer rapid, leaf dehydration occurs due to defective regulation mechanisms making stomata of tissue culture stay open. Epidermis as well as stomata cells were observed already on the leaves in in vitro conditions, but they become physiologically functioning only after transfer into conditions of natural environment.
Przy zastosowaniu mikroskopu scaningowego porównywano cechy budowy komórek liści pochodzących z 100 letniej rośliny matecznej, 8 tygodniowych kultur tkankowych oraz 1 rocznych regeneratów. W regenerantach z kultur tkankowych obserwowano więcej nienormalności w budowie komórek epidermy, komórek szparkowych i komórek przyszparkowych w porównaniu z komórkami pochodzącymi z rośliny matecznej. Podczas przenoszenia tkanek w kulturze in vitro obserwowano odwodnienie tkanek liści a mimo to komórki szparkowe pozostawały otwarte. Komórki epidermy oraz komórki szparkowe były obecne na liściach hodowli in vitro jednak stawały się one fizjologicznie funkcjonalne tylko wtedy gdy zostały przeniesione do warunków naturalnych.

Opis:
Explants of apical buds of sandy everlasting Helichrysum arenarium L. Moench sterilized with calcium hypochlorite – Ca(OCl₂) were placed onto Murashige- -Skoog (MS) growth medium enriched with 1 mg∙dm⁻³ KIN (kinetin) in two consecutive passages. To optimize the procedure of in vitro micropropagation, the axillary shoots of Helichrysum arenarium L. Moench were transferred during the third passage onto 9 different combinations of MS medium without plant growth regulators (PGRs-free medium), with different concentrations of KIN (1.0, 3.0, 4.0, 5.0 mg∙dm⁻³) and KIN (1.0, 3.0, 4.0, 5.0 mg∙dm⁻³) with IAA (indole-3-acetic acid) (0.5 mg dm⁻³). The highest mean number of shoots (24.7) was observed on MS medium with 5 mg∙dm⁻³ KIN and 0.5 mg∙dm⁻³ IAA. The achieved branched shoots were rooted and acclimatized. Rhizogenesis was intensified by the presence of growth hormones: 0.5 mg∙dm⁻³ IAA or 0.5 mg∙dm⁻³ IBA (indole-3-butyric acid). At the stage of acclimation of plantlets the application of a water solution of MS salts (25%) for watering the plants increased the efficacy of plant acclimation from 56 to 75%.

Moench wykładano w dwóch kolejnych pasażach na pożywkę MS [Murashige i Skoog 1962] wzbogaconą w 1 mg∙dm⁻³ KIN (kinetyna). W celu optymalizacji procedury mikrorozmnażania w kulturach in vitro w trzecim pasażu pędy boczne inokulowano na 9 wariantów pożywek MS bez regulatorów wzrostu, z dodatkiem KIN (1,0; 3,0; 4,0; 5,0 mg∙dm⁻³) oraz KIN (1,0; 3,0; 4,0; 5,0 mg∙dm⁻³) i kwasu indolilo-3-octowego – IAA (0,5 mg∙dm⁻³). Największą średnią liczbę pędów (24,7) odnotowano na pożywce z dodatkiem 5 mg∙dm⁻³ KIN (kinetyna) i 0,5 mg∙dm⁻³ IAA (kwas indolilo-3 octowy). Uzyskane pędy boczne poddano ukorzenianiu i aklimatyzacji. Proces ryzogenezy intensyfikowała zawartość regulatorów wzrostu 0,5 mg∙dm⁻³ IAA i 0,5 mg∙dm⁻³ IBA (kwas indolilo 3-masłowy). Na etapie aklimatyzacji mikrosadzonek zastosowanie do nawadniania 25% roztworu soli MS spowodowało poprawę efektywności aklimatyzacji roślin z 56 do 75%.

Opis:
Japanese larch (Larix kaempferi Sarg.) is one of the most frequent exotic species in Polish woodlands. The basic object of research comprised 60 stands of the studied species, located mainly in the northern and western parts of Poland. The growth results for the studied species, evaluated on the basis of the average height (hg55), were compared with data describing the local climate and the stand location within the botanical and climatic zoning. The results confirm the opinion that the Japanese larch prefers a climate of maritime character and generally shows high degree of flexibility regarding its climatic requirements (very large differences between the growth conditions in the studied area and the country of origin). The dependence between the growth results and precipitation is however lower than expected. The most interesting results include the relatively clear connection between the height of the larch stands and the Degórski’s (1984) ‘floristic’ ‘K’ (continentality) index.

Opis:
In this study, we investigated responses of the mid-successional species Acer truncatum Bunge and the late-successional species Quercus variabilis Blume to three solar illumination conditions: (1) constant low light (CL), (2) constant high light (CH) and (3) low light first and high light afterwards (LH). The last treatment was to simulate a canopy opening. Both species exhibited increases in biomass, totally and in part, and decreases in leaf water content, specific leaf area and chlorophyll concentrations in LH treatment compared to CL treatment. For A. truncatum, exposure to high light condition (LH) increased crown area, and decreased root to shoot ratio, stem mass ratio and leaf perimeter. However, for Q. variabilis, LH treatment increased stem diameter at ground height, effective quantum yield, photochemical quenching and decreased maximum photosystem II quantum yield. The biomass allocation pattern did not change in Q. variabilis among three light conditions. With respect to newly developed leaves, no significant differences were found in leaf size of Q. variabilis between LH treatment and CH treatment while that of A. truncatum decreased in LH treatment. All chlorophyll fluorescence parameters in newly developed oak leaves in LH treatment increased compared to those of CH treatment while no difference was found for A. truncatum between LH and CH treatment. A. truncatum displayed a greater overall plasticity than Q. variabilis although the oak seedlings have a greater plasticity with respect to chlorophyll concentration and chlorophyll fluorescence parameters. A. truncatum should be a better candidate for vegetation recovery, especially in places with heterogeneous light conditions.

Opis:
Autoradiographic studies of 3H-uridine incorporation (20-min incubation) and dynamics of radioactive particle translocation from nucleolus into cytoplasm (following 80-min postincubation in non-radioactive medium) in root meristematic cells of soybean have been carried out. The experiment was performed with plants subjected to 4-day acclimation in chilling or subjected to 2-hour cold stress and control plants. Three cultivars of soybean: Mazowia, Polan and Progres (cultivated in Poland) were used in the experiment. It has been shown that in control conditions the greatest number of RNA precursor is incorporated into nucleoli after 20-min incubation. Following 80-min postincubation cytoplasm is the most radioactive area of the cell - this mainly testifies to dynamic translocation of radioactive ribosome subunits from nucleolus into cytoplasm. In chilling conditions the reduction of 3H-uridine incorporation into cells occurs, as compared to control conditions. Plants subjected to a 4-day acclimation incorporate the radioactive precursor more intensively than plants subjected to cold stress. Following 80-min postincubation - in the case of acclimated plants - the nucleolus is the most radioactive area of the cell, which testifies to accumulation of pre-rRNA in it. After the cold stress cytoplasm is more radioactive than the nucleolus. In all three cultivars the processes of synthesis and transport of pre-rRNA particles are similar, only their intensity is different. Morphometric measurements of nucleoli in all cultivars subjected to 4-day chilling have shown that root cell nucleoli are larger than those in control. This phenomenon can be connected with stronger inhibition of rRNA transport than its synthesis.

Opis:
The aim of this work was to find statistical relationships between the concentrations of accessory pigments in natural populations of marine phytoplankton and the absolute levels and spectral distributions of underwater irradiance. To this end, empirical data sets from some 600 stations in different parts of the seas and oceans were analysed. These data were obtained from the authors’ own research and from the Internet’s bio-optical data base. They included the vertical distributions of the concentrations of various pigments (identified chromatographically) and the vertical and spectral distributions of the underwater irradiance measured in situ or determined indirectly from bio-optical models. The analysis covered a total of some 4000 points illustrating the dependence of pigment concentration on underwater irradiance characteristics, corresponding to different depths in the sea. The analysis showed that the factor governing the occurrence of photoprotecting carotenoids (PPC) is short-wave radiation λ < 480 nm. A mathematical relationship was established between the relative PPC concentration (relative with respect to the chlorophyll a concentration) and the magnitude of the absorbed radiative energy per unit mass of chlorophyll a from the spectral interval λ < 480 nm, averaged in the water layers Δz = 60 m (or less near the surface) to account for vertical mixing. This absorbed short-wave radiation (λ < 480 nm) was given the name of Potentially Destructive Radiation (PDR∗(z)). Analysis of the relationships between the concentrations of particular photosynthetic pigments (PSP), i.e. chlorophyll b, chlorophyll c, photosynthetic carotenoids (PSC), and the underwater irradiance characteristics indicated that these concentrations were only slightly dependent on the absolute level of irradiance E0(λ), but that they depended strongly on the relative spectral distribution of this irradiance f(λ) = E0(λ)/PAR0. The relevant approximate statistical relationships between the relative concentrations of particular PSP and the function of spectral fitting Fj , averaged in the layer Δz, were derived. Certain statistical relationships between the pigment composition of the phtyoplankton and the irradiance field characteristics are due to the photo- and chromatic acclimation of natural populations of marine phytoplankton. These relationships can be applied in models of the coefficients of light absorption by phytoplankton.

Opis:
Existing statistical models of in vivo light absorption by phytoplankton (Woźniak & Ostrowska 1990, Bricaud et al. 1995, 1998) describe the dependence of the phytoplankton specific spectral absorption coefficient a∗ pl(λ) on the chlorophyll a concentration Ca in seawater. However, the models do not take into account the variability in this relationship due to phytoplankton acclimation. The observed variability in the light absorption coefficient and its components due to various pigments with depth and geographical position at sea, requires further accurate modelling in order to improve satellite remote sensing algorithms and interpretation of ocean colour maps. The aim of this paper is to formulate an improved model of the phytoplankton spectral absorption capacity which takes account of the pigment composition and absorption changes resulting from photo- and chromatic acclimation processes, and the pigment package effect. It is a synthesis of earlier models and the following statistical generalisations: (1) statistical relationships between various pigment group concentrations and light field properties in the sea (described by Majchrowski & Ostrowska 2000, this volume); (2) a model of light absorption by phytoplankton capable of determining the mathematical relationships between the spectral absorption coefficients of the various photosynthetic and photoprotecting pigment groups, and their concentrations in seawater (Woźniak et al. 1999); (3) bio-optical models of light propagation in oceanic Case 1 Waters and Baltic Case 2 Waters (Woźniak et al. 1992a, b, 1995a,b). The generalised model described in this paper permits the total phytoplankton light absorption coefficient in vivo as well as its components related to the various photosynthetic and photoprotecting pigments to be determined using only the surface irradiance PAR(0+) surface chlorophyll concentration Ca(0) and depth z in the sea as input data.
