La pr\u00e9sente contribution est une exploration des aptitudes germinatives de semences de trois g\u00e9notypes de bl\u00e9 dur, permettant d\u2019appr\u00e9cier le niveau de vigueur de celles-ci. Le pourcentage de germination, la cin\u00e9tique de croissance \u00e0 un stade juv\u00e9nile, le test d\u2019absorption d\u2019eau en sont quelques param\u00e8tres effectu\u00e9s. Un autre param\u00e8tre physique, \u00e0 savoir la taille des semences, a aussi \u00e9t\u00e9 pris en consid\u00e9ration\u00a0; pour appr\u00e9cier l\u2019effet intra et inter vari\u00e9t\u00e9s. Les r\u00e9sultats auxquels nous avons abouti montrent que le pourcentage de germination, exprim\u00e9 apr\u00e8s 5 jours et 10jours ne semble pas discriminant \u00e0 ce point et les r\u00e9sultats, malgr\u00e9 de l\u00e9g\u00e8res variations restent quelque peu similaires. La cin\u00e9tique de croissance, quant \u00e0 elle, pr\u00e9sente des diff\u00e9rences entre les g\u00e9notypes \u00e9tudi\u00e9s. Le test d\u2019absorption d\u2019eau a montr\u00e9 que les g\u00e9notypes pr\u00e9sentent une bonne vigueur. Au champ, il est \u00e0 remarquer le caract\u00e8re distinctif de pr\u00e9sence de cire (compos\u00e9 donnant une texture lisse des feuilles) chez la vari\u00e9t\u00e9 Ammar6, ce qui lui conf\u00e8re en principe des qualit\u00e9s adaptatives de tol\u00e9rance au stress hydrique. Cette \u00e9tude nous aura permis une exploration pr\u00e9liminaire simple, rapide mais fiable tout autant, des semences, avant leur utilisation dans des essais en plein champ.<\/p>\n
