🔎 The composition of biostimulants is constantly changing and improving. Some phytohormones are already familiar to farmers (such as auxins, cytokinins and gibberellins), and some are almost new.. 🧐

✏️ But not everything is so terrible with them, because we will try to explain in more detail the role and functions of phytohormones of the “new generation”.

🔷 BRASSINOSTEROIDS – were identified as the sixth plant hormone after the classical plant hormones auxin, gibberellins, cytokinin, abscisic acid and ethylene. In structure, they are similar to steroid hormones of animals. Brassinosteroids play a critical role in various aspects of plant biology: cell division and elongation, root growth, photomorphogenesis, stomatal and vascular differentiation, seed germination, immunity, and reproduction. Play a role in shaping plant responses to stress, such as low temperatures, drought, salinity, disease, heat, and nutrient deficiencies. This subfamily of hormones, even at a very low concentration (10⁻¹⁰ M and below), regulates a wide range of processes in plant development and responses to environmental stresses.

🔶 TRIACONTANOL – being an endogenous plant growth regulator, promotes numerous metabolic processes in the plant, which contributes to their better growth and development. Moreover, it plays an important role in the formation of stress tolerance and mitigation of stress effects in cultivated plants by activating resistance mechanisms. Triacontanol activates the activity of the root system and promotes the development of vegetative mass, increases the assimilation of carbon dioxide and improves photosynthesis, increases the content of chlorophyll, increases enzymatic activity and promotes the absorption of minerals, which increases the efficiency of the use of basic fertilizers; promotes seed germination and rooting, increases the content of dry protein, which contributes to the maturation of plants.
