Abstract :
This research was carried out to investigate the effect of mycorrhizal fungus Glomus intraradices on concentration of some mineral nutrients in seedlings of Bakraee and sour orange. The experiment involved a factorial combination of two species Bakraee (natural hybrid of citrus) and sour orange (Citrus aurantium) and three culture media (non-sterile soil without fungi, sterile soil without fungi, and sterile soil with mycorrhizal fungi) in a completely randomized design. Seeds of Bakraee and sour orange were sown in pots containing different culture media. The studied attributes were concentration of phosphorous (P), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn) in shoots. There was significant difference (P<0.05) in concentration of these nutrient elements in shoot of mycorrhizal treated sour oranges compared to non-mycorrhizal ones. The concentration of nutrient elements was more in shoot of Bakraee inoculated with mycorrhizal fungus, and significant difference (P<0.05) was observed (except for iron) compared to non-inoculated sterile soil. In conclusion, the results showed that G. intraradices increased the concentration of phosphorous, iron, zinc, manganese and copper in shoots of Bakraee and sour orange seedlings.
