Streszczenie: Being widely used in medicine fructan polysaccharides are also considered the protective agents to various abiotic stresses. Antarctic mosses must have characteristics of extremal adaptation so studying their adaptation mechanisms including fructan synthesis appears promising. Moss different species tolerance to the effect of increased salinity (NaCl), increased nitrogen content (NH4NO3), low and high (+4 and +38oC) temperature abiotic stress factors was measured by the level of moss surviving, the coefficient of reproduction and the fructan content in plant extracts. W.fontinaliopsis plant samples appeared the most tolerant to modeled abiotic stress conditions, comparing to the other studied moss species. Salt and nitrogen stress effect led to fructan content increasing in W.fontinaliopsis plants comparing to control non-effected samples while high temperature stress effect caused nearly ten-time fructan content increasing. The neutral comet assay was performed in order to evaluate the moss extracts UV protective activity and showed the decreasing of the DNA damages level depending on the extract concentration.
