    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.
