Résumé
The main objective of this study was to determine the number and species of plants that emerged from the surface two centimeters of soil collected from three locations : 1) under the canopy of creosotebush plants ; 2) form open areas dominated by creosotebush but outside the canopy of the plants ; and, 3) from a mesquite dominated site. Also species present on the sites in the field were compared with those species emerging from collected soil in the greenhouse under different soil moisture levels.... For each of the three locations the total number of different species found on the sites was higher than the number of species emerging form the collected soil. No mesquite plants emerged in soil collected from mesquite location or either of the creosotebush locations ; nor did any creosotebush plants emerge in soil collected from the mesquite site.

Mots Clés : creosotebush, germination, mesquite, germination, seedling germination
