Arbuscular mycorrhizal fungi (AMF) can affect their host plants growth through nutrient uptake enhancement. Determination of chelators (siderophores and phytosiderophores) in root leachates is of importance in order to account for the effects of AMF on nutrient uptake by plants. In this study, tomato plants were inoculated with either Glomus intraradices or Glomus etunicatum or left un-inoculated as non-mycorrhizal control, in pots containing sterile and acid washed perlite. Rorison’s nutrient solution harbouring three levels of Fe, Mn, Zn and Cu (full strength, half strength and without micronutrients) was applied to the pots during three month- growth period. Root leachates were collected and total chelator concentration was quantified by titration with DTPA. Plant roots showed lower mycorrhizal colonization in this condition. The amounts of chelators produced by roots were significantly different in AMF species. In plants inoculated with G. intraradices, the highest chelator production occurred in the absence of micronutrients and in its half strength as well, but the micronutrient levels had no significant effect on chelator production in plants inoculated with G. etunicatum. In the absence of micronutrients, chelator production was higher in G.intraradices inoculated plants compared to the G. etunicatum ones.
