Abstract. The article presents data on the systematical structure, ecological groups, and areal classes of Rosa L. genus spread in the flora of the Nakhchivan Autonomous Republic. As a result of researches in the Nakhchivan Autonomous Republic, the concept of 30 species of Rosa L genus was developed and spreading of these species by vertical heights, as well as geographic range classes based on regional and zonal principles, were determined.

Аннотация. В статье представлена систематическая, флористическая и экологическая характеристика видов рода Rosa L., распространенных в Нахичеванской автономной республике. В результате исследований была разработана концепция 30 видов рода Rosa L. и определено распределение этих видов по вертикальным высотам, а также флористическим регионам на основе региональных и зональных принципов.

Introduction

Either cultivated or wild plant biodiversity has undergone natural historical, ecological, and anthropogenic impacts. The people don&t always make use of these resources efficiently at all. So that, people cut the forests, destroy the habitat of the plants, more cattle graze in the hayfields and pastures, which are the main food basis of animal-husbandry, inhibit the natural re-growth vegetation by carrying out intensive mowing process in the meadows around the forests, clearing off the forests, foster the lands to fall out by becoming salty. Instead, greenery and natural re-growth measures are less focused on. Consequently, the process of erosion accelerates and the flora composition of forests, lawns, pastures are changing. Initial plant cover perishes; their space is occupied by less significant secondary plants. In such plant phytochromes the amount of nutritious, herbal, honey-giving, oily, and other useful species is decreasing, which are regarded as valuable for

their farming significance. Harmful, poisonous, and weed plants prevail among them which are not eaten by cattle.

For this reason, exploration of taxonomic composition, ecological groups, areal types and classes, their importance, and the role of vegetation of dog-rose species spread in the flora of Nakhchivan AR is considered to be essential.

Materials and Methods

The researches have been implemented since 2018. Different regions of Nakhchivan AR are chosen as the research territory while species with Rosa L. genus have been selected as an object.

In the specification of species, the following works have been used Vascular plants of Russia and the Commonwealth of Independent States (within the former USSR) by S. K. Cherepanov [1], Analysis of flora of the Caucasus by A. A. Grossgeim [2], Flora of Azerbaijan [3], Taxonomic spectrum of the Nakhchivan Autonomous Republic flora by A. M. Ibrahimov, T. H. Talibov, A. V. Matsyura [4], methodical aid titled In the territory of Nakhchivan Autonomous Republic the trees and shrubs of the Rosaceae family by A. Sh. Ibragimov, M. Z. Piriev, D. Sh. Ganbarov [5], Notes on the origin of species Rosa foetida Herrm. var. bicolor (Jacq.) E. Willm. by A. M. Iskenderov [6], "Roses. Phylogeny and systematics." by V. G. Khrzhanovsky [7], Red Book of the Republic of Azerbaijan [8].

Experimental part

Dog-rose species are met in various growth environments of Nakhchivan AR. They are met from plains to sub-Alpine and Alpine zones, in the suburbs of the forests, in the shrubs, in the river sides and in rocky areas [9-10].

One of the leading families in the plant cover of Nakhchivan AR is Rosaceae Adans. During the research that we carried out, 30 species of Rosa L. genus have spread in the area of research.

As species of R. nisami Sosn. and Rosa karjaginii Sosn. noted in the table above, spread in minimum amount in small areas and became endangered natural resources. They were included into Red Books of Azerbaijan and Nakhichevan AR and R tuschetica Boiss., R. sosnovskyi Chrshan., R. rapinii Boiss. Balansa, R. pimpinellifolia Bunge, R. foetida Herrm. were included into the Red Book of Nakhchivan AR for efficient and consistent usage [8, p. 385-405].

Environmental factors are too various. Water is of great significance as an ecological factor in spreading of the plants to vast areas, in different climatic conditions, in distribution to various territories and in formation of different classifications. According to the areas compatible to different humidity degrees, plants are distinguished from each other for various ecological groups (Table).

Mesophytes among Rosa genus is represented by 15 species and it makes up 50% of total species present in the flora. Mesophytes include the species as R. canina L., R. kazarjanii Sosn., R. sosnovskyi Chrshan., R. tomentosa Sm., R orientalis Dupont ex Ser. and so on.

Xerophytes are drought resisting plants. When water increases on the land, they make it vaporize. Xerophytes can absorb water from very wide areas thanks to strongly evolved root system.

When there is potent drought period, height growth of the plant halts, its leaves come off gradually. Xerophytes with Rosa species are represented by 7 species and this constitutes 23.33% of total species in the flora.

Xeromesophytes include Rosa brotherorum Chrshan., R. afzeliana Fr., R. subafzaliana, R. hemisphaerica Herrm., R. tuschetica Boiss., R. multiflora Thunb. while mesoxerophytes are R. pimpinellifolia Bunge, and R. floribunda.

During the researches, geographical and areal classes have been ascertained on the basis of zonal and regional principles of species included in Rosa genus spreading in the territory of Nakhchivan AR (Table).

Reflecting the bond between the flora of the region and the flora of big territories covering this region, where the areal types of species are researched leads to the exploration of migration ways from historical point of view.

As seen from the Table, Atropatena (11), Caucasus (10), Front Asia (4), Europe (4) areal classes are prevalent and this accounts for 87.87% of the total species. The rest areal classes include 4 species, and this comprises 12.12% of the total species in the flora.

While defining the species pertaining to Rosa type according to altitudes, 5 physically-geographically differing vertical zones have been taken and their ecological condition, their spreading altitudes have been specified and regularities have been explored. The diagram reflects spreading of species according to vertical altitudes (Figure 4).

There appeared some hardships in exact determination of borders of species in noted zones. So, there are such species that were met only in one zone, while species belonging to Rosa genus come across in some zones. For instance, R hemisphaerica Herrm., R hracziana Tamamsch., R. sachokiana Jarosch. and other species are met around-forest shrubs of mountains, while Rosa canina L., R orientalis Dupont, R sachokiana Jarosch., R pimpinellifolia Bunge and others come across in the bushy slope from mountainous zones to sub-Alpine zones.

Undoubtedly, carried out researches do not reflect the species completely belonging to Rosa L. genus that spread in the territory of Nakhchivan AR. In our further researches, exploration of those species in detail is considered appropriate.
