Recently, climate change, reduction of species diversity, and food problems are among the problems that worry the whole world. Plants play an important role in solving these problems. For this purpose, we introduce various food, medical, and industrial plants. One of the plants with different fields of application is the species belonging to the genus Berberis L. For this purpose, the bioecology of Berberis L. species was studied to regulate the ecological balance. To study the introduction and adaptation of Berberis L. species to the Absheron conditions on a scientific basis, it is important to evaluate the biological and morphological features of these species at individual stages of development.During the introduction of barberry species, it is a very important issue to study the biology of individual development of each species. Ontogeny - the individual development of the species - covers the period from the zygote to the natural death of the species. Information about the morphological characteristics of the species is obtained in the developmental stages of ontogenesis.
