The universality of the pathways of morphogenesis in vivo, in situ and in vitro allows to choose a model for the study of regularities and peculiarities of morphogenetic processes in plants including embryonic and early post-embryonic development. A perspective model systems in this field of study are the callus cultures in vitro. This article presents the brief review of the literature and own data obtained during the investigation of phytohormonal characteristics of the induction of callusogenesis and morphogenesis in vitro in cereal calli. The dependence between phytohormonal status of explants and their ability to the formation of calli as well as morphogenesis of calli in vitro was demonstrated. The methodological technique, consisting in identifying and using the optimal balance of endogenous (in explant) and exogenous (in nutrient medium) auxines, allows to approach the ways of morphogenesis in vitro manageable in the callus model systems.
