The effects of Piriformospora indica and Glomus mosseae on some growth and physiological parameters, and cadmium (Cd) amounts in Triticum aestivum cv. Sardari39 plants under the toxic levels of Cd were investigated. The experiment was carried out including four treatments (P. indica inoculation, G. mosseae inoculation, co-inoculation of G. mosseae and P. indica, and non-inoculation), each having four Cd concentrations (0, 0.3, 0.6 and 0.9 mM Cd). In non-inoculated plants, by increasing Cd concentration in the soil, growth parameters, chlorophyll content, performance index (PI) and Fv/Fm were reduced, whereas root and shoot Cd accumulation were increased. The colonized plants with P. indica and G. mosseae (in solitary or together) had higher growth, chlorophyll content and PI compared to control. In the presence of P. indica, the Cd concentration was increased in roots, whereas it was decreased in shoots under higher soil Cd concentrations. The presence of G. mosseae decreased root Cd concentration under lower Cd concentration in the soil. Results from this study indicate that P. indica inoculation yielded greater readings of growth parameters, chlorophyll content, PI, root colonization and also reduced shoot Cd content compared to G. mosseae inoculation.
研究了内脐蠕孢菌（Piriformospora indica）和摩西球囊霉（Glomus mosseae）在小麦（Triticum aestivum cv. Sardari39）植株受到镉毒性水平影响下，对一些生长和生理参数以及镉（Cd）含量的影响。该实验包括四个处理（内脐蠕孢菌接种、摩西球囊霉接种、摩西球囊霉和内脐蠕孢菌共同接种、不接种），每个处理有四个镉浓度（0、0.3、0.6 和 0.9 mM Cd）。在未接种的植物中，随着土壤中镉浓度的增加，生长参数、叶绿素含量、性能指数（PI）和 Fv/Fm 降低，而根和地上部镉积累增加。与对照相比，单独或共同接种内脐蠕孢菌和摩西球囊霉的植物具有更高的生长、叶绿素含量和 PI。在存在内脐蠕孢菌的情况下，根中的镉浓度增加，而在较高土壤镉浓度下，地上部镉浓度降低。本研究结果表明，与摩西球囊霉接种相比，内脐蠕孢菌接种可获得更高的生长参数、叶绿素含量、PI、根定殖读数，同时降低地上部镉含量。
