Assessment of the success of the introduction of some rare plant species in the Siberian Botanical Garden of Tomsk State University

Abstract

About 300 species of natural flora are currently in the collection of the laboratory of rare plants of the Siberian Botanical Garden of Tomsk State University (TSU). 6 species of rare plants of the natural Siberian flora, included in the Red Book of the Tomsk Region, were the objects of this study: Aconitum anthoroideum DC., Allium obliquum L., Erythronium sibiricum (Fisch. et C.A. Mey.) Krylov, Potentilla erecta (L.) Raeusch., Primula macrocalyx Bunge, Thymus marschallianus Willd. Evaluation of their successful introduction was carried out using scales proposed by various authors. Its own unified scale for the introduction of rare and endangered plants of the natural flora of Siberia has been developed. It was established on the basis of the analysis that the species studied upon introduction into the southern taiga subzone of Western Siberia belong to medium resistant (Thymus marschallianus), resistant (Aconitum anthoroideum, Allium obliquum, Erythronium sibiricum, Potentilla erecta) and highly resistant (Primula macrocalyx).
