Resumen
In intensive and sustainable agriculture, it is not enough to use plant protection products and fertilizers, but it is also important to control plant physiological processes. The aim of this study was to determine the effect of Tytanit on Festulolium braunii (K. Richt.) A. Camus dry matter yield, photosynthetic activity and the content of chlorophyll and selected chemical compounds. The pot experiment was conducted in 2019 in a plant breeding room. Four levels of treatment were used: control with no treatment and three stimulant concentrations of 0.02%, 0.04% and 0.06% in the spraying liquid. In particular, the research included the determination of dry weight of plant roots, dry weight of plants, chlorophyll a and b content in leaf blades, maximum and actual efficiency of the leaf photosystem, coefficients of non-photochemical and photochemical fluorescence quenching, and the content of total protein, crude fiber, monosaccharides, crude fat, crude ash, Ca, Mg, P and K in the dry matter of plants. Used in controlled conditions, the stimulant contributed to an increase in most parameter values, increasing photosynthetic activity and the content of chlorophyll a and b, total protein, calcium, magnesium and potassium, but it reduced the amounts of crude fiber.
