DEVELOPMENT HISTORY AND MORPHOLOGICAL CHARACTERISTICS OF SPECIES OF THE GENUS OAT (AVENA L., POACEAE BARNHART) OF THE AZERBAIJANIAN FLORA

Abstract

Taxonomy, development history, results obtained on the basis of a morphological study of species of the genus Oat (Avena L.) of the Azerbaijani flora and intragenus characters based on the available literature data were studied in this article. It was determined that the species within the genus differ sharply from one another due to a number of morphological characteristics.
As a result of the research, it was found that the oat species differ from one another according to the size of the spike scales. In soft-flowered oat, suspicious o. the lower spikelet scale is 2 times smaller than the upper spikelet scale; in soft-flowered oat, suspicious o., Bruns o., viest o., slender wild o. and so on., the tip of the flower scale is long, but in wheat o., hairyleaf o., Ludovik o. the end part is a short axis; hairyleaf o.and byzantine o. have hairy stem joints, but in others they are bare.
