To establish salinity tolerance of some grass species, seeds of 10 perennial grasses: Festuca pratensis, Lolium perenne, Festuca arundinacea, Dactylis glomerata, Festuca rubra, Alopecurus pratensis, Agrostis gigantea, Phleum pratensis, Phalaris arundinacea, and Bromus inermis (each of them with two varieties) were exposed to NaCl concentration of 0,100,150,200,250 mM. The effect of applying saline solutions on germination rate, shoots and roots lengths, fresh weights of roots and shoots and salt tolerance index was investigate. The seed germination as well as the seedling development were inhibited with increasing salt concentration to almost all the grass species and with differences between species and varieties. The species Festuca pratensis (Transilvan2 36.3%, Tămpa 19.5%), Lolium perenne (Mara 47.5, Măgura 64.2%), Festuca arundinacea (Brio 37.2%,Adela 26.5%), Agrostis gigantea (11-204 45.7%, 11-196 38%), Phleum pratense (Alpina 30.3%,Tirom10,8% )and Bromus inermis (Iulia Safir 35.5%) they had a good tolerance index at level 250 mM NaCl.
