Endophytic fungi can have a positive impact on phytoremediation of heavy metals, but the effects of endophytic fungus Microdochium bolleyi on extraction of Cd by barley, have not been previously examined. Therefore, the objective of the present study was to assess the effects of M. bolleyi (strain B26) on cadmium (Cd) tolerance, accumulation and translocation by barley (Hordeum vulgare L.) (Sararood cultivar) under Cd stress. Barley plants were inoculated with B26 in Cd-added sands (0, 10, 30, 60 mg Cd kg⁻¹ sand), and the various attributes of growth along with the amount of Cd in barley were investigated after two months. The results indicated that fungal inoculation significantly improved (p < 0.05) plant growth in the presence of Cd by enhancing factors of plant growth; shoot length increased by 8.93%, 11.61% and 5.59%, root length by 26.47%, 12.39% and 13.95%, dry root biomass by 6.35%, 8.57% and 28.57%, dry shoot biomass by 11.39%, 8.25% and 4.81% in soil containing 10, 30 and 60 mg Cd kg⁻¹, respectively. The increases in chlorophyll content were 16.74% and 9.97% under 10 and 30 mg Cd kg⁻¹ treatments, in turn. In terms of Cd accumulation, fungal inoculation increased the amount of Cd in the barley roots, by 44%, 27.95% and 25.18% in soil containing 10, 30 and 60 mg Cd kg⁻¹, respectively, but it remained the same in plant leaves whether the plants were inoculated or not. The results suggested B26 can be exploited to improve the potential of barley for the remediation of Cd contaminated sites.

内生真菌可对重金属的植物修复产生积极影响，但以前尚未研究内生真菌大麦d对大麦提取Cd的影响。因此，本研究的目的是评估bolleyi菌株（B26株）对Cd胁迫下大麦（Hordeum vulgare L.）（Sararood品种）对镉（Cd）的耐受性，积累和转运的影响。大麦植物在添加了Cd的沙子（0、10、30、60 mg Cd kg ^-1沙子）中接种了B26，两个月后研究了大麦生长的各种特性以及Cd的含量。结果表明，真菌接种明显改善（p < 0.05）通过增强植物生长因子在镉存在下的植物生长; 苗长增加了8.93％，11.61％和5.59％，根长增加了26.47％，12.39％和13.95％，干根生物量增加了6.35％，8.57％和28.57％，干苗生物量增加了11.39％，8.25％和4.81％在分别含有10、30和60 mg Cd kg ^-1的土壤中。在10和30 mg Cd kg ^-1处理下，叶绿素含量的增加依次为16.74％和9.97％。就镉的积累而言，真菌接种使大麦根中的镉含量增加了，在含10、30和60 mg Cd kg ^-1的土壤中，Cd的含量增加了44％，27.95％和25.18％。分别，但是无论是否接种植物，其在植物叶片中都保持相同。结果表明，可以利用B26来提高大麦对Cd污染部位的修复潜力。
