    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.

    CHANGES IN GROWTH REACTIONS OF ENCRUSTED MAIZE SEEDS DURING STORAGE
    (CEP USM, 2024) Borovskaia, Alla; Lutcan, Elena; Ivanova, Raisa; Mascenco, Natalia; Vanicovici, Nicolai
    The purpose of the research was to study the effect of storage time on biometric parameters during the germination of encrusted seeds. A differential effect of seed encrustation on germi nation, growth of roots and seedlings depending on the hybrid was revealed. After 12 months of storage, the encrusted seeds showed an increase in overall germination by 2.0-5.5% compared to intact seeds. It has been established that pre-sowing encrustation of maize seeds with a bio conjugate containing the genistifoliosides, biologically active substances of natural origin, and a film-forming agent (sodium salt of carboxymethylcellulose) helps to preserve the sowing qualities of seeds during long-term storage and improves the biometric parameters of germinated seeds.
