Festuca arundinacea Schreb. is an important cool-season perennial grass, used in parks, home lawns, athletic fields, golf courses and soil conservation sites. Recent researches are directed towards a deeper understanding of its behaviour under different stress conditions and increasing the ability to counteract the effects of global climate change. This study was carried out with a view to evaluate the effects of saline and drought on some standard germination and early seedlings growth indicators, in laboratory conditions. Both types of stress had significant negative effects on physiological indicators, but the influence of saline stress have proven to be more prominent, especially as regard as mean germination time. The effect of seeds priming was also evaluated. Priming with ASFAC-BCO-4 (a Romanian agricultural biostimulator) stimulated the germination process, i.e. it hastened it, compared with the untreated control, and the effects were more noticeable at the beginning of germination. Also, it positively affected early seedling growth, as well as chlorophyll synthesis, even if the saline stress was present.
