dc.description.abstractThe 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.en
dc.description.abstract În această lucrare a fost redat efectul tratării semințelor de grâu hexaploid Moldova 5, Missia și Kuialnik cu biostimulatorul (BS) Reglalg asupra activității fotosistemei II a frunzei steag, a recoltei în perioada de formare și maturare a boabelor în spic. Experiențele au fost efectuate între anii 2015-2018 pe Câmpul Experimental al Institutului de Genetică, Fiziologie și Protecție a Plantelor, USM. Durata totală a fazelor de formare și maturare a boabelor în spic la plantele soiului Moldova 5 a constituit 26 de zile, iar la plantele soiurilor Missia și Kuialnik – 33 de zile. Aplicarea BS Reglalg a contribuit la extinderea duratei de formare și maturare a boabelor în spic cu 1-3 zile. În variantele martor recolta a fost de 3,76-4,20 t/h, iar în cele experimentale –3,81-4,73 t/h. Eficiența tratamentului semințelor cu BS Reglalg a variat în funcție de soi și de condițiile climatice ale anului.ro
