Department of Commodity, tourism and law Kabardino-Balkaria State Agrarian University Nalchik, Russia e-mail: [email protected] Abstract - The article presents the results of studies of Among the species of Inula, which grow in the North diversity of species and condition of cenopopulations of Inula L. Caucasus, britannica and germanica species are of particular species in ecotopes of the Central Caucasus on the example of interest. These species are used for various purposes, such as Kabardino-Balkaria republic. Inula L. genus is represented by medicine, food industry, feed production, beekeeping, Inula helenium L., I. orientalis L., I. magnifica Lipsky, I. ornamental plant growing. [4]. The goal of this study is to grandiflora Willd., I. britannica L., I. ensifolia L., I. germanica evaluate diversity of Inula L. species and estimate the L., I. aspera Poir., I. conyza DC., designated to various conditions of cenopopulations of Britannica and germanica altitudinal belts. The results of the analysis of I. britannica и I. species in ecotopes of the Central Caucasus on the example of Germanica cenopopulations are indicative of the necessary Kabardino-Balkaria republic. activities to protect and reproduce the species by: restricting cattle grazing, establishing a seed bank for complementary seeding in damaged plant associations, creating conditions for II. METHODS AND MATERIALS vegetative and seed reproduction, building reserve populations. We used the materials of natural observations and expeditions in Kabardino-Balkaria republic in 2014-2017 to Keywords- Inula britannica L., Inula germanica L., phytocenosis, cenopopulation, areal, ontogenetic spectrum, vitality. study diversity of species and phytocenotic environment of the species of Inula L. genus. Condition of I. britannica и I. Germanica cenopopulations was evaluated. Censuring of I. INTRODUCTION quantity and age structures was performed using transects 1m One of the objectives of vegetative studies is evaluation of wide and 10 m long; transects were divided into square areas condition of rare and endangered cenopopulations, as well as by 1m2; 20-30 areas for each habitat. A censuring unit for species that are typical for a certain territory and are of cenopopulation’s evaluation was a specimen of generative resource and economic value. Representatives of Inula L. ontogenetic state, for which we measured several genus are such species for Kabardino-Balkaria republic. morphometric parameters (sprout height, number of leaves, Previous studies of species diversity and condition of length and width of middle canopy leaves, anthode diameter, cenopopulations of Inula were performed sporadically, mostly number of seeds in one anthode, number of semiflorets in one in a form of mentioning in botanical references and anthode). For our evaluation, we used the vitality index identifications. [1-3]. In view of current increasing (IVC), age index (Iв), index of reproduction(Δ) and anthropogenic impact (ploughing, pasture degradation, effectiveness (ω) [5-7]. The type of cenopopulation was recreational impact), areals of many species are narrowing and identified by the “delta-omega” classification[7]. Statistical becoming focal. Hence, investigation of diversity and analysis included correlation index(r), calculation of variation cenopopulation of Inula L. species is relevant in order to (CV) and minimum significant difference at 5% significance develop activities on rational use, protection and reproduction. value (НСР05) [8].

RESULTS AND DISCUSSION where Botriochloa ischaemum L. is dominant. Graminaceous According to our botanical research, 9 species of Inula plants are subdominant: (Bromopsis riparia (Rehmann) Holub, were identified on the territory of the republic. Horse-heal Cynodon dactylon (L.) Pers., Elytrigia repens (L.) Desv. ex (Inula helenium L.) can be found in all areas of the republic, Nevski). The following legumes are represented in the except the highlands. The largest root harvest is typical for phytocenosis: Trifolium repens L., T. pratense L., Medicago sub-mountain areas and highest belts of mountain areas (520- lupulina L., Lotus corniculatus L. Mized herbs are as follows: 1600 m A. S. L). Exploitable volume of roots for this species Achillea millefolium L., Origanum vulgare L., Cichorium is approximately 60 t, and it is possible to harvest intybus L., Salvia verticillata L., Plantago lanceolata L., P. media L., Galium verum L., Ligusticum scoticum L., approximately 10 t per year. Inula orientalis L. is represented in the flora of alpine and subalpine meadows (1500-3100 m A. Convolvulus arvensis L., Onopordum acanthium L., Thymus S. L.) The largest root harvest of this species is typical for marschallianus Willd. mountain area. Exploitable volume of roots for this species is In the phytocenoses of mountain steppe meadows (Cherek, over 4 t, whereas it is possible to harvest around 1 t.[9]. Inula Chegem and Baksan gorges at an altitude of 900–1400 m A. S. magnifica Lipsky is endemic to Caucasus and can be found L.) Inula britannica L. can be found in mountainous beard- only at subalpine belt of the republic (1250–2100 m A. S. L.) grass steppes. The following species are subdominant in Inula grandiflora Willd is endemic to Caucasus and grows on phytocenoses: Cynodon dactylon (L.) Pers., Festuca valesiaca alpine and subalpine meadows up to 3000 m A. S. L. Inula Gaudin, Setaria pumila (Poir.) Schult., Koeleria gracilis Pers., britannica L. grows in all areas, except the highlands. Areal of Stipa capillata L., S. lessingiana Trin.&Rupr., Bromopsis Inula. ensifolia L. covers the steppe area of the republic, as riparia (Rehmann) Holub, B. inermis (Leyss.) Holub, Bromus well as the Upper-Balkar arid basin (500–1200 m A. S. L.). arvensis L., Elytrigia repens (L.) Desv. ex Nevski, Eragrostis Inula germanica L. can often be found in plant associations of minor Host, Agropyron fragile (Roth) P. Candargy, the steppe area and arid basins. Inula aspera Poir is widespread Agropyron desertorum (Fisch. ex Link) Schult. The following in the areas from the lowlands to medium altitude (1200–1800 legumes are identified: Trifolium pratense L., Medicago m A. S. L.). Rocky patches (2000-2400 m A. S. L.) host Inula falcata L., M. lupulina L., Lotus caucasicus Kuprian. ex Juz., conyza DC. The majority of Inula species in the republic are Melilotus officinalis (L.) Pall.

Koch is dominant in the an altitude of 400-600 m A. S. L. (flatlands and moderate herbage of forb-feather meadow steppes (west of the Baksan slopes of the Cretaceous ridge) in humid floodplains of the river), whereas graminaceous plants are subdominant Malka, Baksan, Cherek, Chegem rivers, in the roadside, near (Koeleria gracilis Pers., Bromopsis riparia (Rehmann) Holub, canals and settlements.
