ANATOMICAL STRUCTURE OF VEGETATIVE ORGANS OF NITRARIA SCHOBERI L. (SULAKSKY POPULATION, DAGESTAN)
Aim. The article is devoted to the study of the anatomical structure of the vegetative organs of Nitraria schoberi L. growing on saline soils in the Caspian lowland of Dagestan and to the analysis of some of its features in relation with its habitat.

| description | Aim. The article is devoted to the study of the anatomical structure of the vegetative organs of Nitraria schoberi L. growing on saline soils in the Caspian lowland of Dagestan and to the analysis of some of its features in relation with its habitat. Methods. Were studied 10 samples of leaves, stems and roots of N. schoberi. Preparations of temporary specimen as well as the description of tissues and cells of vegetative organs of N. schoberi were carried out in accordance with conventional methods. Results. The main tissues of leaf, stem and root of N. schoberi are described; their quantitative estimation is given; ecologically significant adaptive anatomical signs are also identified. Conclusion. The presence of a thin cuticle, dense mesophyll, water-preserving tissue, large stomata and deposition of excess salts in containers to maintain high osmotic pressure of the protoplasm is associated with the phreatophytic nature of N. schoberi which allows the species grow on saline soils at high air temperatures. The increase of the proportion of vessels in the xylem of shoots with age in comparison with the cells of the libriform is associated with an increase in water demand for successful photosynthetic processes and thermoregulation in the conditions of the Caspian lowland. The obtained data can be used in a comparative evaluation with other ecotypes of N. schoberi and of the genus Nitraria. |
