This work aims at dormancy in medics. At the same time, the storage effect of eleven years. The best results are obtained by mechanical scarification (with glass paper). The percentage of germination reaches up to 100%. However, the average passage in the liquid nitrogen also gives high results, the average germination of passage of the seed in sulfuric acid at 98% for 60 minutes is 65.63% approaches the control. With the mechanical method we noticed that the dormancy differs between species with big seed and small seed. Within the small seeds M polymorpha have a very high germination rate compared to M truncatula. On the other hand, in large seeds it is homogeneous and the germination rate is very close between M. ciiliaris and M. intertexta. Regarding storage, there is no significant difference in germination between populations harvested in 2004 and those harvested in 2012 and treated in 2015, ie 11 years of storage, for all scarification processes. Moist heat treatment was the exception, accounting for 40% of germination variations (p <0,05) and mechanical scarification seems very efficient, easy to apply in the field, and the scope of the farmer but the breaking of seeds is inevitable, so it can be replaced by liquid nitrogen treatment which does not cause breakage or the removal of the seed coat in a short time.
