Perspectives for the conservation of rare species of the genus Potentilla L. (Rosaceae) of the flora of the Republic of Bashkortostan

Abstract

The article presents the results of the primary introduction experience of rare species of the genus Potentilla L. (Rosaceae Juss.) of the flora of the Republic of Bashkortostan. There are 5 rare species in the collection: the Pleistocene relic species Potentilla agrimonioides Bieb., P. arenosa (Turcz.) Juz., P. nivea L., the South Ural endemic P. eversmanniana Fisch. ex Ledeb., the Ural endemic P. kuznetzowii (Govor.) Juz. These species are included in the Red Data Book of the Republic of Bashkortostan (2021). In the collection, each species is represented by one sample. The mobilization was carried out by seeds from natural populations. Species of the genus Potentilla were grown in monoculture in the introduction nursery of the Ufa Institute of Biology. Plants go through a full cycle of annual development of shoots and give viable seeds (except P. arenosa). According to the scale of introduction resistance proposed by N.V. Trulevich (1991), under cultivation in the forest-steppe zone of the republic, P. agrimonioides and P. kuznetzowii are resistant species, P. eversmanniana and P. nivea are weakly resistant, P. arenosa is unstable species.
