Blackstonia perfoliata (L.) Huds. belongs to the family Gentianaceae. Due to a high content of biologically active secondary metabolites (gentiopicrin, swertiamarin and sweroside) this species has been described as a possible substitute for Centaurii Herba – a bitter remedy for treatment of digestive system disorders. Yellow wort is widespread in European and African regions of the Mediterranean and in Western Europe, mainly on calcareous grasslands habitats and fixed sand dunes. Therefore, the environmental conditions such as salinity and osmotic stress are very important for the growth and development of this species. The germination recovery from salt stress conditions of three populations of B. perfoliata collected from different natural habitats was examined. Germination rate, germination velocity and rate of germination recovery were tested. Results showed that germination characteristics depended on NaCl pre-treatment and were population-specific. Increase in salt concentration inhibited seed germination and germination recovery rate. Additionally, seeds of B. perfoliata population collected from sandy locality of Vojvodina showed different germination pattern in comparison with seeds collected from saline habitat; salt treatment improved their germination rate, but also attenuated germination velocity response.
