Description
This work was carried out on the natural territories in the collection and of the Yakut botanical garden (JBG). The object of study was medicinal plants used in the treatment of cardio-vascular system. On the natural territories JBG we have noted 39 species of medicinal plants. 26 species were studied in a culture

VARIETY OF LEGUMES IN NATURAL COMMUNITIES OF THE YAKUT BOTANICAL GARDEN
DescriptionThe article provides the information about the species diversity of the family Fabaceae in the natural area of the Yakut botanical garden. It also provides the information about the method and the study area, a description of the ambient phytocenotic, taxonomic analysis, areal analysis, bio-morphological analysis (the variety of life forms) given by K. Raunkier, rhythm analysis, environmental analysis (by A.P. Schennikov), analysis of phytocoenotic. We have also provided a summary of the endemics of Central Yakutia - Thermopsis lanceolata R. Br. subsp. jacutica (Czefr.)

A VARIETY OF ASTERACEAE IN NATURAL COMMUNITIES OF THE YAKUT BOTANICAL GARDEN
DescriptionThe article provides information about the species diversity of the family of Asteraceae in the natural area of the Yakut botanical garden. We provide the information about the method and the area of the study, the description of the phytocenotic surrounding, taxonomic analysis, areal analysis, bio-morphological analysis (the variety of life forms) which was given by the K. Raunkier, rhythmological analysis, environmental analysis (by A.P. Schennikov), analysis of phytocoenotic

Description
The article presents materials on studying distribution and phytocenotic confinedness of relict steppe species of Astragalus angarensis. Astragalus angarensis is the endemic of the Angara region and Yakutia, it is a relict species. Three small isolated fragments express the area of species. The largest fragment was found in the Angara region; the smallest two fragments are occurred in the valley of the Lena river, in the southwest Yakutia near Olekminsk and in the central Yakutia, from Yakutsk to Bulgunnakhtaakh village. Ecological and geobotanical characteristics of habit area of Angara Astragalus is given; floristic content of community is studied. The described desertificated Krascheninnikovia, Psathyrostachys steppes and also Festuca, Agropyron, Koeleria and Artemisia communities with Astragulus angarensis confined to slope habitats, characterized by poor floristic content that gives evidence of low competitiveness of this species

INTRODUCTION OF IRIDACEAE IN CENTRAL YAKUTIA
DescriptionThe results of introduction test of species and cultivars variety of irises in the Central Yakutia are described in this article. Climatic conditions of the introduction region are extreme and they are strong restrictive factor at introduction to the culture of many other species and cultivar of decorative plants. The condition of plants after rewintering was estimated on a 4-mark scale. Total number of the plants which were lost in the first winter (0 points) is 126 species and cultivars that is 60,9%. For 01.06.2015 year a collection of irises in Yakutia makes 40 exemplar of species (22 species) and 31 exemplar of cultivars (30 cultivars), 7 species of them are successfully adapted (3 points) (Iris biglumis Vahl., I. bloudowii Ledeb., I. potaninii Maxim., I. scariosa Willd., I. setosa Pallas ex Link., I. tigridia Bunge, Pardanthopsis dichotoma (Pallas) Lenz). The listed species annually plentifully blossom, form seeds and intensive form escapes. Four species Iris biglumis, I. scariosa, I. bloudowii, Pardanthopsis dichotoma are form stable self-seedling

RESOURCE POTENTIAL IN LUTEOLIN-7- GLYCOSIDE VERONICA INCANA (SCROPHULARIACEAE) IN CENTRAL YAKUTIA
DescriptionThe article reveals luteolin-7-glucoside accumulation in the overground part of Veronica incana L. It assesses resource potential of V. incana depending on the phytocenotic conditions of coenopopulations growing in Central Yakutia. Collection of the material was carried out during V. incana flowering in 7 coenopopulations and in the collection of the Yakut Botanical Garden. Analysis of flavonoids content was performed by HPLC method. The high levels of flavonoids content in the biomass of generative plants marked in coenopopulations that are in optimal conditions, and the lowest - in coenopopulations experiencing strong anthropogenic influence. In addition, one of the factors reducing the content of flavonoids in plants is low light intensity in habitat. The highest resource potential on the luteolin-7- glucoside observed in biomass V. incana, growing in fescue grassland steppe and culture

ECOLOGICAL PATH "CHOCHUR-MURAN" ON THE NATURAL TERRITОRY OF YAKUTSK BOTANICAL GARDEN
DescriptionThe article presents the data about flora and vegetation of the territory of the Yakut Botanical garden, where an ecological trail will be; there is a characteristic of plant communities and their classification. Preliminary, the flora of the ecological path includes 310 species of higher vascular plants belonging to 54 families and 172 genera

SEED GERMINATION OF SPECIES RANUNCULACEAE OF YAKUT FLORA
DescriptionThe work was done based on the collection of the natural flora of the Yakut Botanical Garden. The object of research was the seeds of 22 species of the family Ranunculaceae. It is known that the seeds of many buttercup characterized morphophysiological tranquility associated with hypoplasia of the fetus (Nikolaeva, 1988; 1999), due to what delayed the germination of their seeds. Laboratory germination of seeds of the studied species varies from 0 to 100%. Among them, we have not found the kinds seeds which have explosive or fast germination (1 type of seed germination). The germination of the studied seeds states ranging from 6-7 days or more. The studied seeds were evenly distributed between 2 (12 species), and 3 types of seed germination (10 species). Type 2 is characterized by slow germination, type 3 - poor germination or lack of it
