Abstract
Rhodiola rosea (Crassulaceae) is a traditional adaptogen medicinal plant.
Several studies have described that the species shows significant diversity in morphological characteristics.
Furthermore, according to several experiments, not only the age of the plant but also the geographical origin has an influence on the secondary metabolites profile of roseroot.
The aim of our work was to investigate variations among Finnish roseroot populations.
Roseroot is living in the northern parts of Finland, around latitude 69°. We examined eight habitats, of which six were found around Kilpisjärvi (500 m elevation) and two were on the Halti hill (1000 m elevation). Six individuals were selected from all populations.
The inter- and intra-population variability was examined by the use of ISSR and SSR markers.
The average content in active compounds (rosin, rosavin, rosarin, salidroside) of the populations was also measured, and the variability of the secondary metabolites content was compared with the results of the genetic marker analysis.
Both molecular marker techniques revealed low genetic variability within and moderate variability among the populations, which is similar to that of other Rhodiola species.
