Morpho-Anatomical Features of Artemisia szowitziana (Besser) Grossh., 1934

Abstract

The performed anatomical studies were conducted in accordance with the generally accepted methodology. The research materials (leaf, stem, root) were taken in all morpho-physiological development phases. As a result of the conducted morpho-anatomical research, a number of secret characteristics of A. szowitziana species were determined. A. szowitziana is a perennial, 50-60 cm or more tall, with oblong leaves. Fruiting pods are numerous, erect and branching slightly above the middle. The leaves of the lower stem are stalked, 2.5-3.5 cm long. Middle stem leaves are sessile. The mesophyll leaves are amphistomatic, isolateral-palisade type, the upper and lower epidermis contains small-celled palisade tissue. The thickened epidermal cells of the stem have 2-3 layers of collenchyma, homogeneous, polygonal and thin-walled bark parenchyma. The rhizodermis roots are covered with a single layer rhizodermis, 35-45 μm thick. Underneath the rhizodermis is a single-layered exoderm, 5-6 layered bark parenchyma, endoderm and pericycle. Since there is little humidity in summer and autumn in arid zones, the root develops very intensively in the humid period. As a result of the conducted research, it was determined that the species A. szovitsiana has the nature of adaptation to the environment, which is one of the structural characteristics of the general genus.
