In highly stressed ecosystems, symbiosis between plants and has beneficial effects on plant growth. The objective of this study was the effects of two dark septate endophyt fungi against mycorrhizal (Glomus mussea and Glomus interaradices) and Piriformospora indica on Spinach growth in without and with drough stress (Field Capacity (FC) and 50% FC). This study was done at Bu- Ali sina university of Hamedan greenhouse (2015-2016). The percentage of root colonization, wet and dry weights, contents of chlorophyll and some of micro- and macronutrients have been analysed in some adult treated plants after six weeks. The colonization results showed that all studied fungi can effectively enter into spinach roots. Inoculation with Glomus mussea increased the wet weight (20 g/plant) of the plants. Also, some morphophysiological and physological properties such as dry weight (4.1 g/plant), chlorophyll content (2.7 mg/gwd) and potassium to sodium ratio (8.4) were increased when plants inoculated with Curvularia specifera. However, high phosphorus content (311.2 mg/100gwd) measured in plants that was inoculated with Glomus interaradices. Generally, this study shows dark septate endophyte could be benefical in grwoth of spinach as much as mycorrhizal and Piriformospora indica symbiosis.
