Structural Features of the Vegetative Organs of Allium kysylkumi Kamelin. Growing in the Conditions of Kyzylkum
Abstract: The article presents the results of studies of the anatomical structure of the vegetative organs of Allium kysylkumi 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, anomocytic type; isolateral-palisade type of leaf mesophyll; the conducting bundles 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, folded 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. In the vegetative organs of Allium kysylkumi, especially in the leaf, xeromorphic characters are pronounced, which indicates the fitness of this species in natural habitat. The revealed structural diagnostic signs of vegetative organs are species-specific, and show the adaptation of this species to its natural habitat, these micromorphological signs are taxonomic significance for distinguishing and identifying Allium species.
