Arizona cypress tree is an imported species whichis widley cultivated in Iran. In the recent years, due to the use of unconventional waters for landscape irrigation, salinity has increased dramatically, and since post-drought stress is considered to be the most important non-biological stress, coping with this stress is very important. Mycorrhizal fungi and growth promoting bacteria, are known to improve plant tolerance to abiotic stresses. In order to investigate the effect of mycorrhizal fungi and growth stimulating bacteria on improving the salinity tolerance, design and implementation of cider was designed. In order to carry out this experiment, seedlings of Arizona cypress were inoculated during traortation. After 150 days, salinity treatments (control, 80, 100 and 120 mM sodium chloride) were placed. After 150 days, physiological and morphological factors were evaluated. The results showed that mycorrhiza fungus with the highest fresh and dry weight of shoots and roots, highest growth and root length, highest chlorophyll a, chlorophyll b and total chlorophyll content, the highest activity of antioxidant enzymes, the highest potassium content of root and shoot, highest proline concentration, lowest sodium content of root and shoot and the lowest ion leakage rate have been shown to be the best yield and have made the plant more tolerance to salinity stress. Growth promoting bacteria, although in certain traits such as superoxide dismutase activity, ascorbate Peroxidase activity, Proline concentration and potassium content of root and shoot improvement, but in most traits there was no significant difference in comparison with the control plant. The treatment of mycorrhizal fungi and bacteria. Showed to be an unsuitable combination and had the least effect on different traits. As a result, mycorrhizal fungui treatment is recommended as the best treatment to enhance salinity stress: tolerance in Arizona cypress Keywords : Salt stress, Arizona cypress, Pseudomonas, Mycorrhizal Fungi
