Previous studies have shown that the success of artificially seeded ranges depends upon the ability of the species to profit from the prevailing environmental conditions of the region. One aspect of this problem is the germination behaviour in establishing a stand. Therefore, it would be of great interest to study the optimal conditions required for seed germination of some desert native and introduced range plants. WENT (1953), reported that among the factors affecting seed germination in the desert, temperature, and rainfall, play the important roles. In the present ~tudy attention has been directed to the effect of temperature, rainfall, salinity, and depth of sowing on germination of seeds of several range plants. The selected species included in the present study are five native plants namely: Ononis vaginalis, Panicum twrgidum, Oryzopsis miliacea, Pennisetum dichotomum, and Pennisetum ciliare; and five introduced ones (from Montana and Arizona, U.S.A.) in 1956, namely Medicago sativa, Chloris gayana, Panicum antidotale, Panicum maximum, and Panicum colomtum.  aConservation plants  aForage grasses  aNatural resources conservation  aRainfall duration  aSeed germination  aSoil salinity  aTemperature  aVegetation  aXerophytes  aGerminação  aPlanta Forrageira  aSemente1 aEL-MONAYERI, M.  tFlora oder Allgemeine botanische Zeitung.
