the effect of arbuscular mycorrhizal fungi on nutrient concentrations in ohadi (fandoghi) and kalleghouchi pistachio seedlings in kerman region

In order to investigate the effect of arbuscular mycorrhizal fungi (amf) on the concentrations of nutrients in pistachios, a pot experiment was carried out in the greenhouse based on a factorial design in a completely randomized design with three replications and two factors. there were four factors, namely pistachio species at two levels of ohadi (fandoghi) and kalleghouchi cultivars and culture medium factor at three levels (fungi-free nonsterile soil, fungi-free sterile soil, and fungi-containing sterile soil). plants with amf and ohadi and kalleghouchi pistachio seeds were planted in pots containing fungal inoculum. studied traits were concentrations of iron, zinc, manganese, and phosphorus in aerial parts. concentrations of these elements were higher in the aerial parts of ohadi pistachio seedlings treated with amf than the fungi-free conditions with a significant difference at 5% level. concentrations of all elements were higher in the aerial parts of amf-treated kalleghouchi seedlings than the noninoculation conditions in sterile soil. except iron, the other three elements were different significantly at 5% level. overall, it was observed that amf application increased the concentrations of iron, zinc, and manganese nutrients in aerial parts of both cultivars.
