    Evaluation of the biological value of the dandelion leaves (Taraxacum officinale weber ex wigg.) grown on soil contaminated with copper
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Studziński, Mateusz; Grzeszczuk, Monika; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin
    The experiment was conducted in 2013. Research material included the leaves of a dandelion (Taraxacum officinale Weber ex Wigg.) – roots with the above-ground part, gathered before tying of flower baskets (Taraxaci radix cum herba). Laboratory analyses, which were the continuation of the pot experiment, were conducted in the laboratory of the Department of Horticulture of the West Pomeranian University of Technology in Szczecin. In the dried plant material (dandelion leaves) the content was determined: of dry mass and total ash, vitamin C as L-ascorbic acid, chlorophyll a, b and total, total carotenoid and antioxidant activity. Based on the obtained results it was found that both the biometric features of the dandelion plants and their biological value subjected to significant changes depending on the amount of copper contained in the soil and the crop harvest date.

    The influence of fertilisation urea phosphate on growth and yielding bush of two highbush blueberry cultivars (V. Corymbosum)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kozos, Karolina; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin
    An interest in highbush blueberry cultivation is growing in the world. An increase in the demand causes high prices of fruits. The success of cultivation depends on providing soil with a low pH value to the plants. The study specifies the influence of different doses (30 and 60 kg N · ha–1) of physiologically acidic urea phosphate (17.7% N, 44.6% P2O5) on the growth and yield of highbush blueberry shrubs. The studies were carried out at the Department of Horticulture, West Pomeranian University of Technology in Szczecin, at a production plantation specialized in the cultivation of highbush blueberry. The bushes were planted in soil classified as sandy silts with the content of organic matter at 4.1–4.2%. The following parameters were measured in autumn: the height of the bushes, the length of one-year growths, the number of one-year shoots growing on roots, the green index, leaf area and yield, fruit weight and firmness. The use of urea phosphate influenced the increase in the yield and size of fruits of both highbush blueberry cultivars, it did not, however, influence the increase in the height of bushes and the length of one-year shoots. It stimulated the plants to produce shoots growing on roots and the formation of larger leaves with a higher green index value as compared to unfertilized plants.
