The influence of cold treatment on germination characteristics and primary seed growth of two forage species of Lolium rigidum Gaudin. and L. prenne L.

Lolium rigidum Gaudin. and L. prenne L. species, which are from poaceae category are two forage species of high importance in terms of palatability and production. In this investigation, a factorial experiment based on a completely randomized design with three replications was performed, 4, 6, 8 weeks and seeds at 22° C was used as control. Subsequently, parameters such as germination percentage (GP), germination rate (GR), germination value (GV) and germination index (GI) of Lolium rigidum Gaudin. and L. prenne L. were evaluated. The results showed that the effect of cold treatment was significant (p≤0.01) on GP, GV, GI and GR of two species. In general, it can be concluded that cold treatment in the positive way to improve the performance and to increase the seed germination of Lolium rigidum Gaudin. and L. prenne L.
