Climate change effects on agriculture are estimated to be dramatically affected for the next 20 years [15]and up to 2050 and therefore it is a great need for increasing diversity in crops species for improving their ability to deal with drought, floods and harsh conditions generally. The scope of this article was to evaluate three grasses perennial species for their development under experimental drought conditions. Thus, Dactylis glomerata, Festuca pratensis and Lolium perenne were selected for this experiment as they are very important for Romanian grasslands. There have been used two types of seeds for each species: control, certified seeds and regenerated after in vitro cultivation on polyethylene glycol of these three species and obtained in a previous study [2]. Our results revealed that the plants regenerated upon in vitro cultivation on PEG are better adapted to drought conditions.
