Aim. This work is devoted to studying the morphology of the excretory tissue of leaves and secondary metabolites of some species from Inula genus (Inula britannica L., Inula aspera Poir., Inula germanica L.) grown in plant communities of the foothill and steppe zones of the Kabardino-Balkar Republic. Methods. As object of a research served the leaves of an average tier of plants collected in a phase of the complete blossoming
in August, 2015-2016. Applied the standard histochemical test reactions to identification of secondary metabolites. Results. Morphological structure of non-glandular trichomes are typical of the Asteraceae family. Hairs are located on large veins and interveinal region abaxial, rarely adaxial surface of the leaf. The total number of non-glandular trichomes decreases among I. britannica L. – I. aspera Poir. – I. germanica L. Glandular trichomes are located on the abaxial surface of the leaf and have morphological species characteristics. The number of glandular trichomes per 1 mm2 of the leaf surface varies from 1 (I. germanica L.) to 16 (I. aspera Poir.). In the leaves of I. germanica L. are formed endogenous secretory structures: schizogenous intercellular spacese, idioblast, latex vessel. The secondary metabolites of I. britannica L. are essential oils, I. germanica L. – essential oils, resins, calcium oxalate, rubber, I. aspera Poir. – essential oils, resins, polysaccharides. Conclusion. Morphological features of secretory tissue and chemical composition of secondary metabolites in the leaves of the genus Inula L. due to the influence of abiotic conditions and associated with the ecological strategy of the species. Differences in the morphology of glandular structures can be used for micro-diagnostics species of the genus Inula L.

ECOLOGICAL TOURIZM AND RECREATION
Aim. The article describes the tourist potential of two large museums of the Krasnodar Territory, the Krasnodar State Historical and Archaeological Museum-Reserve named after E.D. Felitsyn and Krasnodar Regional Art Museum named after F.A. Kovalenko. Much attention is paid to the classification of museums in the Krasnodar Territory. Methods. In the study were used a comparative-geographical method, a systematic approach, an analysis of statistical-mathematical materials and an analysis of the leisure profile of citizens. Findings. A comparative assessment of the potential of two large museums of the region is given. We also conducted an analysis of the survey data of the leisure profile among the townspeople in the city of Krasnodar in order to identify which of the museums is more popular. The main indicators such as the number of storage units, the total exposition and exhibition area, the number of sightseeing visits and mass events, the number of educational programs and exhibitions, the number of employees were examined and analyzed. Distinctions between museums are also noted. Conclusions. An analysis of these data showed that both museums have sufficient tourist potential to represent the city and get acquainted with the city through museums. The results of an analysis of events held in museums to attract visitors are presented. The sufficient tourist potential of two large museums for representation of the city and region is defined. The directions for their development as objects of tourism are proposed.
ENVIRONMENTAL RESEARCH METHODS
EDUCATION FOR STABLE DEVELOPMENT
Aim. The aim of the research is to study the influence of ecological education on the formation of a world outlook for the sustainable development of the society (on the example of schools in the Kizilyurt district of the Republic of Dagestan). Materials and methods. The results of a questionnaire survey of pupils of 5-11 grades and school teachers of 19 schools in the Kizilyurt District served as the materials for the study. The questionnaires were developed at the Institute of Ecology and Sustainable Development (Dagestan State University) which were also successfully tested in other regions of the republic. The data was processed using standard tools as the Statistica and Excel programs. Results. Analysis of the results of the questionnaire survey of pupils in schools in the Kizilyurt District allowed drawing conclusions about the quality of environmental education. The results of the research reveal shortcomings in the planning and content of school curricula. The questionnaires showed unsatisfactory level of the environmental awareness as well as the fact that the only means of receiving environmental knowledge by students is during the study of biology and geography.
Conclusion. The authors evaluated the environmental awareness of students, formulated recommendations for improving the training system and its content for sustainable development of the society.
