DOI:https://doi.org/10.53040/ppap2023.54.With the help of BAS Reglalg, it possible to control the depth of the tillering node in the soil. It was found that the experimental variants had higher levels of PS2 flag leaf activity compared to the control variants. In the heading phase, the activity of PS-2 of the flag leaf is the highest. The use of Reglalg contributes to the preservation of PS-2 activity during the period of intensive aging of the leaf blade, this affects the duration of the accumulation of dry matter of seeds in the ear, delaying the death of the leaf by about 1-2 days.enTriticum aestivum L.grain fillingFS-2tillering nodeflag leafepicotyl lengthArticle
