Use possibilities of species of the genus Rosa L. distributed in the territory of the Nakhchivan Autonomous Republic

As a result of long-term research conducted in the flora of the Nakhichevan Autonomous Republic, the distribution of 34 species of the genus Rosa L. was established, of which 30 are wild and 4 species are found in culture. During the expeditionary research conducted in this territory, taking into account the practical importance of the species Rosa canina L. and R. corymbifera Borkh., which have a wider distribution area, their growing areas were determined, their biomorphological features, chemical composition, the main phytocenoses formed by them were studied, their natural productivity was calculated, and the possibilities of using them in folk medicine and other industries were analyzed. It was found that in folk medicine and various industries, mature fruits of the species Rosa canina L. and R. corymbifera Borkh. are mainly used, therefore, when harvesting, it is necessary to take into account significant differences in their ripening times depending on the altitude above sea level. Taking into account the existing standards and technical conditions, the most favorable period for harvesting fruits in the middle mountain zone is considered to be the second half of September, and in highland areas - the end of September and the first half of October. Despite this, given the large reserves of species of the genus Rosa L. in our republic, as well as their importance in the national economy, medicine and food industry, the organization of systematic procurement of their fruits is one of the urgent tasks. At present, the population uses these natural resources in an extremely limited volume, while hundreds of tons of valuable raw materials remain unclaimed and unused. In the future, they can be used to provide the food and pharmaceutical industries with raw materials, restore forests, ornamental gardening, improve the sanitary and hygienic state of the environment, as well as for the production of some drugs from fruits rich in biologically active substances.
