    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.

    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.
