Ecological adaptation of <i>Astragalus mongholicus</i> Bunge

One of the current research areas is a comprehensive study of plants that are widely used in traditional medicine, with the aim of possible further introduction. Astragalus mongholicus Bunge is a valuable promising medicinal plant used as a part of recipes for many diseases in the practice of Oriental and Tibetan medicine. Astragalus mongholicus is a species belonging to the large genus Astragalus in the family Fabaceae. It is included in the flora of Mongolia vascular plants. The basis of the work was the study of the morphological, physiological and anatomical features of Astragalus mongholicus Bunge, in order to identify the ecological adaptability of the species to the natural and climatic conditions of northern Mongolia. This is a typical long-stem herbaceous polycarpic, hemicryptophyte, has an underground caudex storage organ - for the supply of nutrients and replenishment of buds. It is reproduced by seeds only. The species belongs to the transitional group of plants - xeropetrophyte, which is resistant to water deficiency, populates mountainous steppes. It is a heliophyte that is well developed in conditions of increased solar insolation, with sharp temperature fluctuations during the period of spring growth, development and maturation of fruits and seeds. These adaptations are incorporated in the morphological structure of the biomorph, physiological and anatomical features of the Astragalus mongholicus leaf structure. Based on the conducted morphological and physiological analysis, as well as the anatomical study of the Mongolian Astragalus leaf, it can be concluded that in the course of a long evolutionary development the species is well adapted to the arid climatic conditions of northern Mongolia.
