Abstract

The beneficial soil microorganisms as arbuscular mycorrhizal fungi (AMF) form the mutualistic relationship with plant roots and act as bio fertilizers for saffron (Crocus sativus L.). In the present study, the plant growth, AMF colonization and nutrient uptake of C. sativus evaluated in earthen pots filled with sterile soil. C. sativus seedlings with or without AMF spores of the Glomus species, were cultivated for six months in autoclaved sediment medium. The results of the first year showed a significant increase of the above and below ground growth of saffron plant. crocus-sativusThe fresh and dry weight content indicated in higher levels of inoculated group that the value of biomass was 4.05 (gr) and 0.42 (gr) than non-inoculated group, respectively. The photosynthetic pigments and soluble sugar content increased in the mycorrhiza infected as compared to the non-inoculated ones with rate of 36.69% and 43.1%, respectively. In addition, the mycorrhizal dependency (MD) of C. sativus to AMF reached a maximum of 38.18% under AMF inoculation treatment, which was significant (p < 0.05).
