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

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
