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, as well as 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. Reduction of leaf area is the main morphological feature of xerophytes.
