Özet

The article considers the intensity of growth in the morphological structure and the comparative anatomy of plant vegetative parts in the ontomorphogenesis pertaining to the medicinal plant Rhaponticum carthamoides (Willd.) Iljin. under sowing conditions. It is established that the object of research in the first year of life undergoes a stage of germination, juvenile, immature and virginal life states. The radicle in the vital state of the germination is yellowish in color, erect, with the formation of lateral roots of the first order. In the juvenile state of life, the radicle thickens somewhat. At the juvenile stage and virginal life state, the primary root is thickened, the lateral roots of the first order are not so numerous and poorly developed. In the generative state of life, the intensity of vegetative and generative growth increased. In a young generative state, during a comparative analysis of the anatomical structure of vegetative organs at the stage of ontogenesis, an increase in the number of idioblast cells in which biologically active substances accumulated was observed. The anatomical structure of the root was observed during the generative period of complete formation. The differentiation of idioblasts and the activity of secretory structures in the parenchyma of the primary cortex and the conducting bundle show that the culmination occurs during generative periods, which allows us to scientifically formulate whether the increase and increase in the number of idioblast cells in the primary cortex and conducting root bundle is the time of maximum accumulation of biologically active substances in medicinal raw materials.
