Abstract

In order to evaluate the effect of the Arbuscular mycorhizal fungi (AMF) on Calendula officinalis, an experimental has been carried out in term of salinity stress in totally randomized Factorials in shahrood. The samples were cultivated in tested sandy loam soil. This experiment were conducted in hub seedling (pot) method with four salinity treatment in 1.5-3.5-5.5-7.5 (dSm-1) concentration, two level with and without mycorrhiza in 4 trial. The Fl Calendula seed were cultivated with mycorhizal fungi simultaneously in which the salinity treatment was applied in leaf stage four. The measured characteristics included dry weight, root and shoots, leaf area, number of flowering branches. The result has implied that utilizing the different mycorrhiza salinity stress has a meaningful effect on measured characteristics that is on the dry weight of shoots, the leaf area on 5%, and the number of flowering branches Chlorophyll a and b on the 1%.
