    The role of the flag leaf in the formation of the yield of winter wheat plants (Triticum aestivum L.) grown from seeds treated with the biostimulant reglalg [Articol]
    (CEP USM, 2025) Platcovschii, Nicolai; Dascaliuc, Alexandru
    The effect of treating seeds of hexaploid wheat Moldova 5, Missia and Kuyalnik with the biostimulator (BS) Reglagl on the activity of the flag leaf photosystem II (PS-2) and the yield during the period of formation and ripening of grain in the ear was studied. The experiments were conducted during 2015 -2018 at the Experimental Field of the Institute of Genetics, Physiology and Plant Protection, MSU. The duration of the grain formation and maturation phases in Moldova 5 plants was 26 days, and in Missia and Kuialnik plants - 33 days. The application of BS Reglagl contributed to extending the duration of grain formation and maturation by 1-3 days. In the control variants, the harvest was 3.76 - 4.20 t/h, and in the experimental ones - 3.81 - 4.73 t/h. The efficiency of seed treatment with BS Reglagl varied depending on the variety and the climatic conditions of the year.

    Phenotypic plasticity and plant resistance to abiotic stress
    (CEP USM, 2024-10-07) Dascaliuc, Alexandru; Jelev, Natalia; Ralea, Tudor
    The phenotypic plasticity of cultivated plants exceeds that characteristic of spontaneous plants. Concerning this, the question arises as to why a commensurate level of genome volume did not accompany the high level of crop plant phenotype changes. More and more data are emerging, demonstrating that, due to the rapid activation of phylogenetic adaptation systems stored in the genome, phenotypic plasticity generates non-random adaptation changes. We present the results of assessing the resistance of plants to the action of extreme temperatures and the influence of the biostimulator Reglalg on the viability, resistance, plasticity, and productivity of wheat and pedunculated oak plants.
