The study discussed the phenotypic variation range determined by genetic and environmental variability. The hypothesis presupposes that increased yields generated either by the application of mineral fertilizers and/or the use of cultivars with higher fertility may lead to a reduction in the concentration of minerals in potato tubers, was verified in the study.

The development of the classification utilized sub-daily sea-level pressure values (at the main standard synoptic hours, i.e. 00, 06, 12 and 18 UTC). Sea-level pressure values and physical quantities (resultant flow direction and total shear vorticity) defined 27 circulation types: a) eight each of the directional cyclonic, transitional, and anticyclonic circulation types, and b) one each of the non-directional cyclonic, anticyclonic, and undefined types. In the years 1961–2010, the highest mean precipitation amount in the study area was recorded for cyclonic non-directional type C, followed by cyclonic types with air flow from the western and northern sectors. Type C was also distinguished by the highest number of precipitation events with high intensity irrespective of their duration , i.e. short-term, medium-term, and long-term precipitation events. Moreover, in the class of cyclonic types, precipitation events were considerably longer than in an-ticyclonic and transitional types. On the other hand, for anticyclonic types, precipitation with high intensity was recorded much more rarely, particularly in the case of ad-vection from the southern sector.

The size of the resulting stress depends on the nature of the active substance, time of application, conditions at the application time, fertilization and genetic properties of cultivated plants. Herbicides disrupt the course of photosynthesis, enzymatic transformations, damage chlorophyll, causing excessive transpiration, inhibit cell division (germination, growth). The active substances contained in the herbicides can easily penetrate into the chloroplast, causing damage to the photosystem II and to the complex collecting energy of light. Herbicides interfere with the ratio of chlorophyll a: b and reduce the activity of the electron carriers. As a result, there is a change in the parameters of chlorophyll fluorescence. Therefore, the studies utilized measurements of chlorophyll fluorescence to d...

Comparison of method of obtaining hydrogen "fuel of the future" Hydrogen is an important raw material at chemical industry. As a Biohydrogen seems to be feasible renewable energy carrier that could replace fossil fuels, also. The main problem of the hydrogen is that, the element seldom exists in pure compound form H2. Therefore to obtain hydrogen in volumes suitable to be use as a raw material or biofuel, there is necessity of decomposition compound “rich” in hydrogen. źvery compound, containing hydrogen atoms bounded in its molecule, is a potential source of hydrogen. Potential paths of hydrogen production are being selected due to widespread of raw materials, costs of production of hydrogen, efficiency. The most commonly used or being regarded to be possible way to use in industrial scale are: steam pyrolysis of methane (95% of hydrogen on the market is produced in this way), water splitting, ammonia decomposition, decomposition of organic wastes (biomass). Ways of decomposition of biomass to obtain hydrogen are: dark fermentation, photofermentation biomass pyrolysis, and biomass gasification. This review focuses attention on the way of obtaining hydrogen from biomass by dark fermentation mostly and less in other methods. Dark fermentation is considered to be most stable form biomass decomposition method- spontaneous and feasible also due to possiblity of twenty-four-hour waste management.

Vitamin C, which are rich in tubers of H. tuberosus, stimulates the penetration of nutrients from the skin into the bloodstream, facilitates regeneration and collagen production. Also accelerates the formation of collagen and proteoglycans tissue, that is: proteins, acting as scaffolding, which is responsible for skin elasticity and so is considered to be anti-aging factor. In the case of dry skin vitamin C contained in tubers promotes the synthesis of lipids are responsible for skin hydration and in the case of oily skin reduces the production of sebum. The richness and variety of biologically active compounds determines their valuable and highly desirable cosmetic properties. These components also enrich the skin with biologically active substances, acting cleansing and tending, protective and curative, and consequently - beautifying and revitalizing. Thus, the addition of components to the cosmetics artichoke is a response to the growing needs of consumers.

Dla porównania dokładności prognozy opracowano dla tych samych danych model przy zastosowaniu klasycznych metod statystycznych. Na podstawie analizy wielkości uprawy, plonowania i przebiegu pogody w kilku miejscowościach Polski południowo-wschodniej, w okresie 10 lat, starano się opracować model prognozy uprawy ziemniaka. Zakres pracy obejmował: ocenę warunków przyrodniczych i rolniczych pod względem przydatności do uprawy ziemniaka na terenie Polski południowo-wschodniej; określenie czynników rzutujących na zmienność powierzchni uprawy, plonów i zbiorów ziemniaka oraz wybór danych na podstawie FAOSTAT i GUS; opracowanie modelu prognozy powierzchni i zbiorów ziemniaka.
