Light is an important factor deciding about yielding and morphological characters of Pleurotus carpophores. The objective of the research was to ascertain the impact of period and intensity of lighting on yielding and carpophore morphological features of four strains of oyster mushroom. The following strains were investigated: P. ostreatus: PX, K22 and P80 strains, P. pulmonarius: P20 strain. Fluorescent lamps with Day-Light were used to provide light in the cultivation room. The following lighting periods were used: 6, 10 and 14 hours/day and the applied lighting intensity included: 100, 300, 500 and 700 lx. Lighting exerted a significant impact on yielding. The highest carpophore crop was recorded when the applied lighting intensity was 500 and 700 lx for the period of 14 h/d. The highest mean mass of carpophores was recorded at 14-hour light exposure and 500 and 700 lx lighting intensity. Carpophore morphological features modified by the lighting period and its intensity included the cap diameter as well as the length and thickness of the stem.

The photoelectric effect on the interface of an immiscible media of aqueous lithium chloride solution of 5x 10-2 mol/dm3 concentration and 1,2-dichloroethane containing tetrabutylammo- nium tetraphenylborate of concentrations ranging from 1 x 10-7 mol/dm3 to 5 x 10-2 mol/dm3 was studied. The effects of temperature, light intensity, variation in light-absorbing tetraphenylborate ion concentration and of incident radiation direction on the appearing potential have been studied. The water/1,2-dichloroethane system with lithium chloride (LiCl) in aqueous phase and tet- rabutylammonium tetraphenylborate (TBATPhB) in organic phase dissolved salts has been proposed as the basic system on photochemical studies in the visible light range.

European yew (Taxus baccata L.) is a rare species, but is the focus of great interest because of the species recovery attempts and its use in medicine. The aim of this study was to determine the optimum conditions for the development of the young generation of this species. Four-year old yew seedlings were grown under artificial light reduction: 2, 8, and 30%, as well as in full light. The seedlings were then planted in natural conditions in fenced and unfenced areas. The results of six years field studies indicated that the greatest impact on survival was shown by the light conditions from the period before planting under the canopy of trees. Seedlings from the 2 and 8% of light showed the greatest mortality. The reason was the sudden change in light conditions, because at the time of planting (early spring), there was no reduction of light under deciduous trees. Almost all of the unfenced yew seedlings were grazed by deer, but yew survival in the unfenced group was surprisingly high despite the permanent grazing. This was explained by the high resistance of yew to cutting and the protection of seedlings by a dense layer of Rubus. The results indicated that yew trees require protection against animals for normal development, even if animals have not previously had contact with Taxus and that yew seedlings are very sensitive to sudden changes in light. Both conclusions can be applied in the development of natural and artificial regeneration of European yew and other endangered plants.

In order to improve the physiology of plants, this research evaluated the effect of high-intensity LED light (red, blue and green) on the following variables: germination (PG), hypocotyl length (HL), fresh (FW) and dry (DW) weight, in three types of lettuce seed (White Boston, Romana and Black Simpson). Exposure times with colour light were 12, 6 and 3h, with a complement of time for treatments with 6 and 3h of white LED light. We used a completely randomised design with four replications of 30 seeds. Treatments with green and red light to 12h had increases above 90% in HL against the control for the three varieties. The blue light treatment (3h) increased 23% in FW White Boston variety and the red light (3h) increased 14% the DW variable in Roman variety, compared to the control. In this study, treatments with colour light presented results above the control; however, a treatment with a single type of light is not optimal to improve plant physiology. The physiological responses evaluated showed variation related to the genotype of seed and to the time of exposure to high-intensity LED light, so this type of light is a viable option for improving the physiology of plants.

Taxus baccata L. is a rare and endangered species with restricted occurrence. One or two-year-old yew seedlings occur quite frequently in natural stands of the species, but older seedlings are rarely observed. Therefore we investigated the relationship between light intensity and the growth rate of ten-year-old seedlings of the European yew Taxus baccata (L.). The study was conducted in a preservation area established in 1999 in order to protect the gene pool of the ‘Cisy Staropolskie’ Reserve in the Bory Tucholskie Forest (northern Poland). A total of 570 three-year-old seedlings were planted under the canopy of a 45-year-old forest stand composed of oak (50%), birch (40%) and hornbeam (10%). Measurements of seedling heights were taken in 1999, 2003 and 2005. In 2005, the current annual growth increment was measured. Relative Photosynthetic Photon Flux Density (RPPFD) up to 30% had a positive influence on the height and annual height increment of the yews, but most of individuals grew below 5% RPPFD. This suggests that increasing light level would increase growth of yew in both natural recruitment and planting.

Nodularia spumigena forms extensive summer blooms in the Baltic Sea. The occurrence of the blooms is determined by water temperature, light intensity and nutrient concentration; levels of nitrogen and phosphorus in particular are critical. The time of the seasonal maximum and intensity of the Nodularia bloom in the Gulf of Gdańsk vary significantly from year to year. In 2001 a rapid and massive proliferation of N. spumigena was observed in late June – early July. The concentration of nodularin in water ranged from 90 to 18 135 μg dm−3 and in lyophilised phytoplankton samples from 3000 to 3520 μg g−1 d.w. (dry weight). Such a high concentration of toxin in the recreational waters of the Gulf of Gdańsk constitutes a health risk for users of bathing areas. In 2002, the N. spumigena bloom was less dense, but lasted longer, with a maximum in late July – early August. In 2002 the concentration of nodularin did not exceed 12.6 μg dm−3 in water and 919 μg g−1 d.w. in lyophilised phytoplankton samples. Other cyanobacterial toxins – microcystins and anatoxin-a – were also detected in the coastal waters of the Gulf of Gdańsk.
