The assessment of the current status of Gentiana lutea L. populations of the Ukrainian Carpathians: Ecological and genetic approaches

Abstract Based on the analysis of the genetic polymorphisms (RGAP- and CDDP-PCR) among populations and comparison of these results with ecological characteristics (density, area, spatial and vitality structure, age, ability of renewal and self-maintenance), the status of five natural (Lemska, Gutyn Tomnatyk, Sheshul-Pavlyk, Krachuneska, Troyaska-Tataruka) and one man-made (Pozhyzhevska) populations of Gentiana lutea from the Ukrainian Carpathians was assessed. The results of the complex ecological and genetic analysis have revealed that three populations are unstable (Krachuneska, Troyaska-Tataruka, Gutyn Tomnatyk), two are relatively stable (Lemska, Pozhyzhevska) and only one is stable (Sheshul-Pavlyk). The research results can be used for stabilizing the number of violations and restoring the endangered natural populations. Based on these data, the recommendations for the conservation and protection of G. lutea populations have been developed.
