摘要

The article presents the results of studies of the anatomical structure of the vegetative organs of </span><i><span style="font-family:Verdana;">Allium </span><span style="font-family:Verdana;">kysylkumi</span></i><span style="font-family:Verdana;"> of the Amaryllidaceae family, which grows in the conditions of Kyzylkum (Kokchatau outlier mountain). The characteristic diagnostic features have been determined: the outer membrane of epidermal cells is well developed by the outer folded cuticle, cutinized and more thickened;leaves are amphistomatic;stomata are the most submerged, </span><span style="font-family:Verdana;">anomocytic</span><span style="font-family:Verdana;"> type;isolateral-palisade type of leaf mesophyll;the conducting bundles </span><span style="font-family:Verdana;">are closed, collateral and are arranged in two rows, of which the upper side is represented only by small bundles, in the lower row, 3 large bundles alternate with one small bundle;peduncle and peduncle, parenchymal-beam type of structure;the epidermis is single-row, fold</span><span style="font-family:Verdana;">ed cuticle with more thickened and cutinized;the crustal parenchyma is thin-walled, round-oval, chlorophyll-bearing;the presence of lactic acid is in the cow parenchyma;the primary cortex is separated from the central cylinder by a ring of sclerenchyma;the central cylinder is extensive;closed collateral-type conductive bundles.</span><b> </b><span style="font-family:Verdana;">In the vegetative organs of </span><i><span style="font-family:Verdana;">Allium </span><span style="font-family:Verdana;">kysylkumi</span></i><span style="font-family:Verdana;">, especially in the leaf, xeromorphic characters are pronounced, which indicates the fitness of this species in natural habitat.
