Anatomical Review of Certain Carnations of North Caucasus

The article provides an anatomical review of 32 species of the genus Dianthus L. representatives шт Caucasus, i.e. information about the anatomy of their stem. Most of the studied species have a narrow ecology and are confined to different altitudinal zones. The experience of the introduction of these species in the botanical garden of the Chechen State Pedagogical University of Grozny in the conditions of the steppe climate indicates wide ecological amplitude and potential adaptive capabilities of the species. The main limiting factor in the distribution of these species in natural conditions is probably their low competitiveness. Anatomical signs, apparently, do not have any taxonomic significance. The similarity of the anatomical structure of the stems of the Caucasus carnations is evident even in species that are well differentiated morphologically. Anatomical differences between them are mainly quantitative. The smallest taxonomic values for the anatomical features of carnations are the radial dimensions of the epidermal cells, the mechanical (sclerenchymal) ring, conducting system. The most significant for these purposes are the morphological features: the size of the calyx and capsule, the shape and degree of dissection of the lobule plate, the shape and size of the chaffs

Floristic Research of the Biological Reserve “Bragunsky”

Flora of the biological reserve “Bragunsky” of republican significance, located on the territory of three districts of the Chechen Republic (area of 17,000 hectares, forest land – 10.2 thousand hectares) is studied. Its boundaries are indicated. Preliminary studies in the summer-autumn flora of the reserve have revealed 237 species from 175 genera and 53 families, among which more than 15 endemics are of different statuses, 25 relict species are of different geological eras. Dominant by the number of family species are indicated (Asteraceae, Lamiaceae, Rosaceae, Poaceae, Fabaceae, Caryophyllaceae, Apiaceae, Brassicaceae, Cyperaceae, Scrophyliaceae, Orchidaceae), Geographic elements are considered. The general-holarctic and boreal nature of the flora is noted with a significant participation of ancient Mediterranean and binding elements. The prevalence of hemicryptophytes in the reserve flora has been noted – 115 (49.78 %) species, 48 therophytes (20.25 %) and 40 phanerophytes (10 %) and a slight presence of cryptophytes – 4.21 %. The economically and scientifically valuable, as well as rare, red book and protected species are listed

Crop wild relatives conservation in the Chechen Republic

Background. Plant genetic resources (PGR) conservation is an indispensable condition for ensuring the country's economic and environmental security. The most important component of the PGR status assessment is the study of crop wild relatives in a particular region. This is especially important for the Chechen Republic due to its unique geographic, climatic, environmental and political conditions.Materials and methods. The material for the present research was taken from the published data on the flora of the studied region and the own field studies conducted by the route exploration method. In order to select priority species for conservation, the items of the methodology for PGR conservation adapted for Russia were used. The map of species locations was built using MapInfo 8.5.Results and conclusions. Within the framework of the work on inventoring crop wild relatives (CWR) in the regions of Russia, they were studied in the natural plant communities of the Chechen Republic. A list of 468 species belonging to 120 genera of 35 families has been compiled, which covers over 20% of the entire flora of the republic. Based on the analysis of the CWR species distribution in the studied area, assessment of their economically and biologically important traits, as well as according to the criteria of rarity and vulnerability, a preliminary list has been drawn up for the inclusion in the CWR Red List of the Russian Caucasus. For some species, a map of their location in the studied area was created. For effective CWR preservation, it is recommended to use two methods, that is, in situ and ex situ conservation. However, to date, a more realistic way to preserve valuable species from local populations is to include them in the VIR collection. The Specially Protected Natural Territories (SPNT) System that currently exists in the republic does not provide the necessary protection for natural complexes and individual plant species. The results of the performed study can serve as an additional reason for the establishment of a Chechen State Natural Complex Reserve in the republic
