The roothairs are important components of the root for absorbing nutrients for plants and also secreting the plant-produced secretes. Morphology and their number are influenced by various environmental and internal factors and are regulated by them. Mycorrhizal fungi are established through the root and their presence in the root can affect root’s physical and chemical properties.The aim of this study was to evaluate the effect of the presence of the fungus in the roots on the characteristics of the capillary roots.In order to remove the effect of other microorganisms on the results of the experiment, this experiment was performed in vitro on the roots of the carrot secondary phloem tissue culture. In this experiment, the fungus could affect the characteristics of the root hairs: their number (22% decrease in the root hairs number in the root hair area of the root) and their length (A decrease of 21.3% in the length of capillary roots in mycorrhizal plants). These changes in the characteristics of capillary roots were also caused by the presence of fungal structures in the roots as well as by the decrease in the production of strigolactones. In this study, changes in the production of strigolactones calculated by using their effect on seed germination of Phelipancheaegyptiaca.
