Morphological and Anatomical Analysis of Vegetative Organs of Avena pilosa (Roem. & Schult.) Bieb

The article provides information about the structural features of the fodder plant — Avena pilosa (Roem. & Schult.) Bieb., which is widespread on winter pastures in Azerbaijan. As a result of the morphological-anatomical analysis, important structural elements were identified and the morphophysiology and adaptation of this species. As a result of adaptation to drought conditions, this plant showed signs of strong xerophilization. Xerophytes — plants for which the aridity of the norm. Common symptoms of xerophytes — a small evaporating surface, and other structural and physiological symptoms are very diverse. The reduction of leaf area is the main morphological feature of xerophytes
