Bryophytes are known to avoid salty substrates and do not inhabit the seas. With the purpose of studying the relation between bryophytes and salty environment, gametophytes of the two mosses - Atrichum undulatum, Physcomitrella patens and the liverwort Marchantia polymorpha were grown on MS media enriched with various concentrations of NaCl (50, 100, 250, 350, 500mM) during three weeks at 16/8h photoperiod. Survival and bud formation were drastically reduced in all three species at high salt concentrations and biomass production in M. polymorpha declined almost exponentially as salt concentration increased. P. patens survived concentrations less than 350mM salt quite well. Chlorophyll content (-a, -b and total) in all examined species declined as salt concentration increased, however a modest rise in chlorophyll content in all three species was observed when the concentration of salt in the medium was 100mM. M. polymorpha did not tolerate well concentrations above 250mM according to all the parameters observed.
