Tall fescue is characterised by high adaptability to stress environments (Pecetti et al., 2011), while cocksfoot is particularly tolerant to high temperature stress (Annicchiarico et al., 2011). However, little is known about the effects of temperature stress during drying on the seed of these species. The objectives of the present study were as follows: i) to observe the effects of different drying temperatures on seed germination and dormancy of tall fescue, red fescue and cocksfoot harvested with moisture contents of 45, 35 and 25 %; ii) to test the viability of seeds in different sowing times applied in the continental part of central and south- eastern Europe.
