| contents | <p><span lang="EN-US">The influence of mycorrhizal fungi (<em>Rhizophagus irregularis</em>) on salt tolerance of <em>Cucurbita maxima</em> grown in saline soil was investigated in a pot experiment. The experiment was laid out in a completely randomized design, with treatments replicated thrice. Accordingly, soil salinity significantly (p=0.05) reduced total <span>photosynthetic pigments from 58.06 to 38.06 mg/kg. Mineral contents, biomass yield, AMF colonization </span>were also significantly (p=0.05) reduced<span>. In contrast, m</span>ycorrhizal dependency was significantly (p=0.05) increased in saline soil plants (from 26.91% to 66.45%). Furthermore, inoculation with<em> R. irregularis</em><span> </span>significantly (p=0.05) increased total <span>photosynthetic pigments from 58.06 to 62.06 mg/kg; N from 4.88 to 5.47%; P 860.40 to 896.22 mg/kg; K 4430.00 to 4630.00 mg/kg; Mg 558.99 to 592.10 mg/kg and Ca 2810.00 to 3151.00 mg/kg; biomass yield; leaf dry weight from 0.06 to 0.14g; vine dry weight 3.68 to 5.09g; roots dry weight 0.32 to 0.74 and total dry weight 4.06 to 5.97g, </span><em>R. irregularis</em><span> colonization (from 33.77 to 58.44%) and mycorrhizal dependency </span>in <em>C. maxima</em><span> was evident in </span>both saline and non-saline soil treatments. <span>The results of this work shows that </span><em>R. irregularis</em><span> can enhance the ability of </span><em>C. maxima</em><span> to resist salt stress - possibly through some morphological/ physiological changes, as well as improved vigour, probably via the extensive network of the mycorrhizal roots.
