Résumé :	The hypothesis that large seed size provides an advantage for seedling establishment in dry and /or low moisture was tested in the present study. The work was conducted in laboratory under uniform conditions using an important range of species (66 taxa) with different seed sizes and masses representing a variety of habitats. The study demonstrated that the ecology of the species especially water regime, definitely affect seed sizes. For example, the most favorable water treatments increased significantly the seed size of the plant species. While the unfavorable moisture regime produced species with smaller seeds. Despite its general acceptance in the literature, evidence for association between large seed size and mass and dry habitat is quite limited.
