We investigated differences of salinity tolerance between salt-tolerant (ST) and salt-sensitive (SS) genotypes of yellow centaury (Centaurium maritimum) selected during the germination phase. The ability of in vitro cultured C. maritimum to complete the whole ontogenetic cycle inless than 6 months enabled as to determine salinity tolerance during different growth phases. Based on the physiological attributes measured in this study (growth, morphogenesis, photosynthesis, flowering, seed germination), it can be concluded that C. maritimum genotypes differering in salinity tolerance showed a variable response to elevated salt concentrations during both the vegetative and the generative growth phase.
