Abstract

Plant growth regulators have a wide spectrum of physiological activity. Thanks to their action, resistance of soybean plants to adverse environmental factors, diseases, growth, development and quality is observed. Soy is the most widely used oilseed in the world. The world annual production of soybeans exceeds 260 million tons. It is the main edible plant and the main source of vegetable protein worldwide.The global demand for soybeans is constantly growing as its seeds provide essential proteins, oils and nutraceuticals. In an effort to meet the increased demand for this crop, it has become necessary to introduce cultural practices that promote adaptation to difficult environmental conditions, can improve soybean tolerance to abiotic stress and increase yields. Plant growth regulators are mainly used for this purpose due to their critical role in plant growth and development. One of the main growth regulators are such phytohormones as: auxins, gibberellins, cytokinins, brassinolides, ethylene, abscisic and jasmonic acid. Each of the groups of phytohormones produces its own characteristic action, which is similar in plants of different species. Cell division and elongation, which underlie all processes of growth and morphogenesis, are under the control of auxins and cytokines in plants, so their complete absence can lead to death. These compounds generally have a positive effect on the morphology, physiology and quality of the soybean crop. They are also able to regulate and control to a large extent the processes of growth and differentiation of plant cells. It should be noted that these phytohormones are required in small amounts for the activation and regulation of morphogenetic processes in soybean and other agricultural plants.
