    Extracts derived from spirulina cultivated on media with Cu and CuO nanoparticles as active agents for triticale seed priming
    (CEP USM, 2024) Cepoi, Liliana; Rudi, Ludmila; Chiriac, Tatiana; Zosim, Liliana; Iațco, Iulia; Rudic, Valeriu
    This study investigates the effects of seed priming in triticale using extracts from Arthrospira platensis cultivated with copper nanoparticles (CuNP) and copper oxide nanoparticles (CuONP). Results demonstrate significant increases in chlorophyll, carotenoid, and phenolic content, alongside enhanced antioxidant activity in the leaves. Notably, the treatment with nanoparticle-enriched extracts reduced malondialdehyde (MDA) levels, indicating a protective effect against oxidative stress. The findings suggest that spirulina-based extracts, even with the addition of nanoparticles, can enhance crop health, offering a sustainable approach to agriculture.

    Some aspects of the winter wheat photosynthetic apparatus resistance to drought
    (CEP USM, 2024) Shevchenko, Viktor; Bondarenko, Oksana
    Changes in pigments and proteins content of chloroplast membranes in winter wheat varieties of different resistance under the influence of a drought were studied. The loss of pigments and main structural proteins was greater in less resistant varieties. It was established that the more resistant varieties differed in the increased content of low molecular weight proteins already in the control. Under the drought effects, the relative content of low molecular weight protective proteins increased. Thus, it is shown that the content of proteins of 36, 21 and 16 kDa can be one of the molecular markers of drought resistance.
