Anatomical structure of vegetative organs of the rare species Taraxacum kok‑saghyz L.E. Rodin in immature ontogenetic state

The article contains anatomical characteristics of vegetative organs of rare, endemic, and endangered species Taraxacum kok-saghyz, studied in three populations. The study found that the vegetative organs of plants are characterized by different degrees of development of certain tissues, depending on the place where they grow. The most favorable conditions for plant growth were in the place of population № 3, which was characterized by dark brown mountain soil type, with the layer of black soil (chernozem). It is known that the best soils for the cook-sagyz are strong, regular and leached chernozems – this had main influence on characteristics of growth of plants from population № 3. Since cooksaghyz is hygrophilous plants, the distinctive features of the internal structure of these plants also were affected by water conditions
