Structural Features of the Vegetative Organs of <i>Allium praemixtum</i> Vved. in Different Ecological Conditions

Abstract

Central Asia is one of the main centers of origin of bulbous geophytes, including the family Amaryllidaceae Juss. The anatomical features of many endemic, red-book bulbous geophytes are still poorly understood. The article presents the results of a structural study of the inflated part of the stem (fistular), stem and pedicels of an endemic A. praemixtum species grow in two different environmental conditions in the Aktau mountain Nurata Range (Uzbekistan, Province Navoi) and in the conditions of introduction in the Tashkent Botanical Garden (Uzbekistan, Tashkent city). Diagnostic signs of vegetative organs were revealed and various combinations of xeromorphic and mesomorphic signs were determined. Comparative anatomical study of vegetative organs of A. praemixtum is of great theoretical and practical importance in relation to taxonomy and ecology.
