Abstract
Ontogenesis control is important for developing methods for modeling and yield forecasting potatoes. Knowledge of the mechanisms of phyto-regulation allows for a directed impact on plant ontogenesis. Phytohormone analogs are widely used both in culture in vitro and in vivo; under their influence, the processes of differentiation and callusogenesis take place, morphogenesis and tuberization are induced in vitro, a root formation is induced, seed dormancy is overcome, plant resistance to abiotic stress factors is increased, and protective properties against phytoinfections increases the content of valuable substances and yield. Currently, the list of drugs with pronounced regulatory activity has expanded significantly. Among chemical alternatives, preparations based on microorganisms are most widely used in practice as yield stimulants and resistance inducers. At the same time, there is a growing interest in herbal preparations containing a huge amount of valuable biologically active substances with a different spectrum of action. The growing role and importance of plant growth and development regulators necessitates a deep study of the action nature of these compounds using modern biochemical and molecular genetic methods. At the same time, the search for new strains and drugs that can positively influence plant health and growth under various growth conditions, especially under stress conditions, is relevant. Works in this direction should be intensified due to the constant climatic risks. Creating a science-based system of growth regulation can provide reliable, stable results for potatoes growing in any field conditions of future agriculture.
