摘要：Arbuscular mycorrhizal fungi (AMF) are associated with the roots of over 80% terrestrial plant species. Mycorrhizal fungi are critical and important microbes for plant growth and survival. It is generally accepted that environmental conditions that favor host plant growth tend to maximize mycorrhizal infection and sporulation. Mycorrhizal colonization is known to induce many morphological, physiological and biochemical changes in host plants. Environmental factors and soil conditions influence the occurrence of mycorrhizal associations in ecosystems but it is hard to examine the direct impacts of these factors on mycorrhizal fungi because they rarely occur in nature without a host and members of the glomales cannot be grown axenically. Among the biofertilizers mycorrhizal fungi form the most significant group of soil microorganisms. This review addresses the main abiotic conditions which interacted with mycorrhizal fungi were discussed which included (soil temperature, soil acidity, crop rotation, fertilizer and organic matter , drought stress and soil moisture, pesticides, heavy metals and salt stress).
