BIOLOGY OF SEED GERMINATION OF SOME SPECIES OF FAM. ROSACEAE JUSS
Description
We have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination

INTRODUCTION OF IRIDACEAE IN CENTRAL YAKUTIA
Description
The 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

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

SEED GERMINATION OF SPECIES RANUNCULACEAE OF YAKUT FLORA
Description
The 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

A VARIETY OF ASTERACEAE IN NATURAL COMMUNITIES OF THE YAKUT BOTANICAL GARDEN
Description
The 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

VARIETY OF LEGUMES IN NATURAL COMMUNITIES OF THE YAKUT BOTANICAL GARDEN
Description
The 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.)

RESOURCE POTENTIAL IN LUTEOLIN-7- GLYCOSIDE VERONICA INCANA (SCROPHULARIACEAE) IN CENTRAL YAKUTIA
Description
The 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

CURRENT STATE OF THE COLLECTION OF MEDICINAL PLANTS OF THE YAKUTSK BOTANICAL GARDEN
Description
The article considers data on the stocktaking of plants in the collection of medicinal plants of the Yakut Botanical Garden on the following parameters: the study of the component composition, the inclusion in the Pharmacopoeia articles and the Russian State Register of medicinal products. Introduction test in the collection has been performed for 158 species from 99 genera and 41 families, currently the collection has 101 species from 79 genera and 34 families. Chemical composition of plants is known for 61 species. 17 species are pharmacopoeal and 15 species make medicinal products available. The rest of the medicinal plants can be used in folk medicine. Most represented are Asteraceae family (25), Ranunculaceae (20), Rosaceae (16), Fabaceae (15), Lamiaceae (13), among tested plants. According to the assessment of introduction capabilities, 49 species in the collection are highly stable, 51 - stable and just one is unstable
