The Results of Introduction of Rare and Endemic Plants of Yakutia in the Yakut Botanical Garden

Abstract

The general results of introduction of a collection of species of rare and endemic plants in the Yakut Botanical Garden are discussed. Currently the collection contains 85 species, of which 70 are included in the Red Book of the Republic of Sakha (Yakutia) (including 14 rare endemic) and 15 endemic species, not listed in the current version of the Book. The evaluation of possibilities of introduction of the species showed that from 83 species (2 species Juniperus davurica, Anemone tamarae were not evaluated, because they are on trial for less than 5 years) 54 are highly resistant and stable in culture and 29 species are weakly resistant and unstable. Introduction of rare and endemic plants is very important because it helps to provide:

• the preservation in culture a unique gene pool of rare species;
• the reproduction and accessibility for population of economically valuable rare species, and thus, a decrease of anthropogenic pressure onto natural populations;
• possibility to carry out re-introduction works in damaged natural cenopopulations on the base of cultivated introduction
