Effect of Tytanit and Stymjod on Phleum pratense L. Photosynthetic Activity and the Content of Chlorophyll Pigments

Year: 2025

Type: article

Abstract: The use of Stymjod and Tytanit supports natural resistance mechanisms and improves the condition of Phleum pratense, which is in line with sustainable agriculture and integrated production. The aim of the research was to determine the effect of Stymjod and Tytanit and of the number of their sprays per growth cycle on chlorophyll fluorescence and the content of chlorophyll pigments in Phleum pratense L. leaf blades. The following research factors were used: Factor I—treatment: Control; Tytanit—0.04%; Stymjod—2.5%. Factor II—number of sprays: L1—plants sprayed one time; L2—plants sprayed two times. The use of the Tytanit regulator in the cultivation of Phleum pratense L. contributed to an increase in chlorophyll fluorescence parameters, i.e., qN and qP. In addition, an increase in chlorophyll a and b content was noted. The application of the Stymjod stimulator increased ΔF/Fm′. For the vast majority of chlorophyll a fluorescence parameters, higher values were noted when plants were sprayed two times per growth cycle, i.e., Fv/Fm, ΔF/Fm′, qN, chlorophyll pigments.
