    The aim of this study was to examine an effect of osmotic stress, induced by mannitol (Mn) and sorbitol (So) in concentrations (0–200 mM) on seed germination and development of common soybean (Glycine max L.) seedlings in in vitro conditions. The analysis of the effectiveness of the porcession was made by assessing the length of the stems and roots as well as the fresh and dry mass of 3-week-old seedlings. The biometric index values differed depending on the type of substance used. While Mn at the lowest concentration (50 mM) did not affect the biometric parameters studied, So (50 mM) stimulated the growth of seedlings, root elongation and the number of leaves and fresh weight of plants. The unfavorable effect on biomass was noticed at higher concentrations of both substances. Mn (> 50 mM – <150 mM) negatively influenced the fresh and dry content of the seedlings. In turn, Mn (150 and 200 mM) also caused growth inhibition, decreased number and length of leaves. So (200 mM) significantly inhibited the growth of seedlings, reducing the dry matter.

    The content of isoflavonoids in the green mass of the leading Ukrainian soybean varieties by the vegetation stages were determined, as well as the presence of a series of phenolic compounds in different vegetative organs of soybean of Podilska-1 variety, which is recommended for combined sowing for silage. The scientific evidence of the influence of these compounds on the butter-fat yielding capacity and reproductive properties of cows, which corresponds with the results of years-long usage of corn-soybean silage as a component of forage mixture for high-producing cows under single-type feeding throughout the year within conditions of a dairy unit with 1050 cows.

    In Vitro Selection of Solanum Pimpinellifolium Plant Tolerant to NaCl
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Krupa-Małkiewicz, Marcelina; Kulpa, Danuta; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin, Poland; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin, Poland
    Salinity is a major abiotic stress for plant worldwide which can reduce the average yields of most major crops such as tomato by more than 50%. The response of tomato to salinity is variable depending upon the line or cultivar. The aim of this study was carried out to determine the variation in salt tolerance for wild genotypes of tomato S. pimpinellifolium. To initiate callus tissue different combination of plant growth regulators were added to MS medium. The tolerant forms were selected at the callus stage and the stage of plants regenerated through somatic embryogenesis. Callus culture and shoot explants were exposed to different levels of salinity stress ranging from 0 (control) to 25, 50, 75, 100, 125 and 150 mM NaCl. The highest weight of dark green colour callus was observed on MS medium supplemented with 2.0 mg · dm–3 BAP and 2.0 mg · dm–3 IAA. It was shown that salt stress affected all growth parameters and addition to the MS medium 125 and 150 mM NaCl inhibited callus and somatic embryo initiation. The results obtained in this study suggested that S. pimpinellifolium somaclones isolated from callus selected on MS medium supplemented with 100 mM NaCl showed highest tolerance to salt stress.

    Population Dynamics and Spatial Distribution of Panaphis juglandis (Goeze, 1778) (Hemiptera: Aphididae) on Common Walnut (Juglans regia L.)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Krzyżanowski, Robert; Department of Biochemistry and Molecular Biology, Siedlce University of Natural Sciences and Humanities, Poland
    Common walnut (Juglans regia L.) has gained recognition in Poland as an ornamental species in city environments. More frequent use of walnut in the city landscape has induced a more thorough analysis of the factor that causes a significant decrease in the decorative values of this tree. The aim of this paper was to trace population dynamics and spatial distribution of Panaphis juglandis (Goeze 1778) occupying the J. regia trees. The studies were conducted on walnut trees (J. regia) in Siedlce in the years 2010–2012. Three tree stands in home gardens were selected for observation (H1, H2, H3) and one near the street (H4). Results showed that higher aphid population was found on the studied tree at the street stand in relation to the home gardens trees. P. juglandis were observed on trees growing in street-side stand, where it formed colonies along the main vascular vein on the top part only of the first three external leaflets.
