Abstract
The article provides the brief review of the literature and own works devoted to the peculiarities of the cereal embryonic organogenesis at the early stages of ontogenesis in the conditions of in vitro culture (the so-called somatic embryogenesis, or embryoidogenesis in vitro). Particular attention is paid to the issues of hormonal regulation of the development of somatic cereal embryos from initial cells to mature structures in vitro. A comparison of somatic embryogenesis in vitro with similar events in zygotic embryogenesis in vivo confirms the validity of the principle of universality of morphogenesis processes in vivo and in vitro (Batygina, 2014). The prospects of using somatic embryogenesis in vitro as a model for studying the most complex biological phenomenon – zygotic plant embryogenesis in vivo – are discussed.
