The different studies conducted on natural dynamics of plant cover, germinative properties of seeds, development of root system, and seed production lead to a better understanding of about fifteen autochthonous herbaceous species. Thus, the germinative behavior of grass seeds is controlled by a tegumental inhibition which disappears more or less rapidly as a function of time and conservation conditions; Papilionaceae seeds are said to be hard and can germinate only after cracking of the tegument. In controlled conditions and on natural substrate, the observed rooting speeds range between 2.2 mm/d for the "Koelérie du Valais" to 5.7 mm/d for the "Brome érigé"; they increase when the granulometry of the substrate is finer. Poaceae promote the...
