ONTOGENESIS STAGES OF RED ECHINACEA (ECHINACEA PURPUREA L.) GROWN IN THE CONDITIONS OF SURKHANDARYA REGION

In this article, a medicinal introduced species - Echinacea purpurea (L.) The stages of ontogenesis of the Echinacea purpurea L. plant and their morphological and physiological features were analyzed. During the study, the processes of seed emergence from dormancy, seedling formation, growth rates in the juvenile and immature phases, and the development of the root system and leaf apparatus during vegetative maturity were studied. The ontogenetic sequence of Echinacea purpurea development is an important criterion for assessing its adaptation to a new environment, reaction to agrotechnical measures, and the potential for forming a stable population. The research results create a scientific basis for cultivating this species as a medicinal raw material, improving the processes of introduction, and optimizing phenological observations.
