Abstract

The symbiosis of plants with soil microorganisms leads to the preservation and stability of soil and plant species. Arbuscular mycorrhizal (AM) fungi can enhance the reproduction, growth, health, and resistance of plants to various environmental factors. Overturned tulip is a pasture plant and one of the valuable genetic resources of the country. The aim of this research was to investigate the symbiotic relationship of yellow overturned tulip by AM fungi and the correlation of spore abundance and root mycorrhizal colonization with some physical and chemical properties of soil. For this purpose, 30 soil samples were collected along with plant roots from the habitat of F. raddeana, then some soil properties were measured. After staining the roots and spores extraction from the soil samples, root colonization rate and spore numbers of AM fungi were also measured. Also, the correlation of some soil properties with these fungal factors was investigated. The soil of the plant habitat was silty loam, non-salin, slightly alkalin with moderate content of organic matter and adequate level of N, P and K nutrients. By observing different fungal structures in the plant roots, there was a symbiotic relationship (average colonization of 50%) of AM fungi with the plant and it indicated the mycorrhizal dependency of the F. raddeana in the habitat conditions. The correlation between the frequency of fungal spores and the root colonization was statistically significant at the level of 0.01. Also, no significant relashioship was observed between root colonization and spore numbers with soil physical and chemical properties.
