    Impactul temperaturii și a extractului vegetal asupra germinării porumbului
    (CEP USM, 2024) Luțcan, Elena; Ivanova, Raisa; Borovskaia, Alla; Elisovețcaia, Dina; Spînu, Angela
    The aim was to assess the physiological peculiarities of food corn germination influenced by the extract (JS), obtained from the plant Juniperus sabina L., and to evaluate the combined impact of high temperature at 50°C and treatment with JS. The corn seeds such as super sweet Porumbeni 300 (P300), popcorn Porumbeni 398 (P398) and corn for flour Porumbeni 402 (P402) were studied. Based on the data of oweral germination changes, the seeds of P398 and P402 hybrids were more resistant to heat stress compared to P300 seeds. The JS extract acted as a plant growth regulator, the greatest effect was evaluated in the seed treatment of hybrid P402.

    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.
