Abstract

Hammada elegans is a desert perennial, widely distributed in Saudi Arabia and an effective sand-binder. Germination was tested over a range of fluctuating temperatures and in various concentrations of seawater under two fluctuating temperature regimes. The wide range of temperatures at which seeds on H. elegans can germinate, their high salt tolerance, the synchronization of fruit-setting with optimal conditions for seed germination and subsequent seedling establishment and the massive production of light winged fruits providing effective means of dispersal, all contribute to the success and wide distribution of H. elegans in Saudi Arabia.
