ANATOMICAL STRUCTURE OF PSAMMOPHYTES SPECIES OF THE GENUS ALLIUM L. SYRDARYA RIVER VALLEY

The article presents the results of studying the morphological and anatomical structure of species of the genus Allium L. growing in arid conditions of the Syrdarya River valley (within the Kyzylorda region). The structure of the peduncle and leaf blade of two types of onions Allium caspium (Pall.) M. Bieb is considered. (Caspian onion), A. sabulosum Steven ex Bunge (sandy onion). The species belong to different sections: A. caspium – Porrum Don., A. sabulosum – Haplostemon Boiss. The anatomical structure of these species is practically not studied. When analyzing the species, differences, features and similarities of their anatomical structure were revealed. It was noted that the cross-section of the leaf blade of A. caspium has an elongated oval shape, and A. sabulosum has an almost rounded shape. Given the morphological and anatomical features of the leaf shape, probably the round shape of the leaf blade, A. sabulosum is more adapted to the arid conditions of the Syrdarya river valley. The stomatal apparatus in the epidermis of the peduncles of the Allium species under consideration differs in the depth of location and their number. The anatomical structure of the roots is almost identical in both species
