Salt tolerance of forest tree species as determined by germination of seeds at different salinity levels

Salt tolerance studies were carried out on seeds and seedlings of six species: Acacia arabica, Albizzia lebbek. Parkinsonia aculeate, Prosopis spicigera, Robinia pseudoacacia, Zizphus jujube. The salt concentration was varied from 0.05% to 0.80% for all species. It was found that under the experimental condition Zizyphus jujube, Albizzia lebbek and Acacia Arabica were the most salt tolerant of the species studied.
