    Combination Laser Irradiation Effect on Growth Parameters and Chlorophyll Content of Selected Poaceae Plants
    (New York: Crimson Publishers, LLC, 2022) Prysedskyi, Yuriy; Lahunova, Alina
    The effect of monochromatic coherent light with a wavelength of 635 and 405nm, which was generated by LED lasers with a power of 100mW, was studied to assess growth parameters of some species of Poaceae family plants (Triticum aestivum L., Avena sativa L., Zea mays L.), was. It was found that the germination readiness and germination ability of the investigated plants were likely to increase only with the combined action of red and blue light for 10 sec. Growth parameters of plants significantly increased (10.4-124, 5%) by depending on the dose and spectral composition of the irradiation. The most effective is red light and complex radiation for 10 seconds. The content of chlorophyll a and chlorophyll b is probably influenced by the complex (red and blue light) laser irradiation of seeds.

    Growth Parameters of Herbaceous Plants on Phosphogypsum Dumps with Using Soil Coverings Based on Sewage Sludge
    (Lublin, POLAND: Lublin University of Technology, 2021) Prysedskyi, Yuriy; Mashtaler, Oleksandra
    The phosphogypsum dumps are one of the most toxic solid wastes of phosphoric acid, phosphate and phosphorus fertilizers manufacturing enterprises. In the article the possibility of remodeling of phosphogypsum dumps with using the Poaceae family herbaceous plants seeding was considered. On the basis of determination of growth parameters as well as sulfur and fluorine ions accumulation in the plants, the expediency of the dumps surface covering with a ground-covering mixture consisting of sand and sediment of wastewater in the amount of 10% or 20% by weight is established. In the dumps Bromus inermis Leyss., Dactylis glomerata L., Elytrigia pseudocaesia (Pacz.) Procud., Festuca arundinacea L. and Festuca altissima L. are the most suitable plants for cultivation.
