    Adaptation of beech plants from different provenances to natural growth conditions [Articol]
    (Editura USM, 2025) Elisovetcaia, Dina; Ivanova, Raisa; Popovschi, Ecaterina; Fedorenco, Elena; Brindza, Ján
    This study assessed the adaptive potential of Fagus sylvatica L. seedlings from various provenances under natural growth conditions in the Republic of Moldova. Between 2022 and 2024, seedlings of different ages and origins (Slovakia, Romania, Moldova, and Ukraine) were transplanted and monitored. Key indicators included adaptation rate, survival rate and annual growth. Seedlings from Slovak provenances (Nitra-19 and Rožňava-22) showed the highest initial transplant resistance, with survival rates of 96.15% and 97.00%, respectively. Plants from Ciorești-21 (Republic of Moldova) followed closely, demonstrating the highest survival rate (87.00%) one year after transplantation. Growth assessments showed that although Romanian seedlings (Humosu-20) were initially taller, those from Slovakia and Republic of Moldova surpassed them in growth after one year. Adaptation was influenced by genetic and epigenetic factors, seedling morphology, precipitation levels, and climatic similarity between the origin site and the planting location. These results highlight the importance of selecting suitable provenances sites for beech seed collection and conditions for successful conservation and restoration of beech forests.

    Botanical, phytochemical, pharmacological overview of wild garlic (Allium ursinum) [Articol]
    (CEP USM, 2025) Popovschi, Ecaterina; Ivanova, Raisa
    Allium ursinum L. (ramson, wild garlic), is a perennial herb of Allium genus, known for its medicinal uses and recent growing significance in contemporary phytotherapy. Wild garlic (Allium Ursinum L.) has long been considered a spring vitamin. Past application of A. ursinum exists in the treatment of cardiovascular, gastrointestinal, and respiratory diseases. Current research focuses on its vast phytochemical content - in particular, sulfurous compounds, phenolic acids, and flavonoids - and pharmacological actions, including antimicrobial, antioxidant, and cardiovascular properties. This review summarizes recent data on the botanical, phytochemical, and pharmacological characteristics of A. ursinum, with particular attention to its potential in nutraceuticals and therapy.

    QUALITY CHANGES DURING STORAGE OF BEECH SEEDS COLLECTED FROM DIFFERENT PLACES
    (CEP USM, 2023) Elisovetcaia, Dina; Ivanova, Raisa; Popovschi, Ecaterina; Mascenco, Natalia
    In this study, the changes in quality of Fagus sylvatica seeds collected in 2020 from different places of the Republic of Moldova (Plaiul Fagului, Hîrjauca) and Ukraine (Zakarpattia) on the third year of storage were evaluated. Beech seeds quality maintenance depended on the values of moisture, initial viability and seeds germination. The seeds from the Plaiul Fagului with a higher initial germination 76.7-84.0% and lower moisture content (8.69-9.24%) slightly reduced their quality during storage, by 1.0-2.3%.The germination indices such as germination rate, mean daily germination, average seed germination time, total time of seed germination, were improved by treatment of stored seeds with the natural bioregulator, genistifolioside. Treatment with genistifolioside also contributed to the elongation of seed roots by 17- 24% in all variants.
