Effects of different arbuscular mycorrhizal fungi (AMF) species on some bean (Phaseolus vulgaris L.) cultivars grown in salty conditions

This study was carried out to determine the effects of three different Arbuscular Mycorrhizal Fungi (AMF) species (Glomus mosseae, Glomus intraradices and Glomus fasciculatum) on the growth and nutrient contents of four bean cultivars (Onceler, Seker, Terzibaba and Sehirali) grown under salt stress. The constant amount of NaCl (50 ppm) was added the autoclaved growth medium containing 1:1:1: ratios of soil, sand, and manure. The five gram (25 spores g-1) of inoculum was placed in the seedling growth medium before the seeds were sown. At the end of the study, some nutrients such as N, P, K, Ca, Mg, Fe, Cu, Mn, and Zn and plant growth parameters such as shoot height, stem diameter, root length, leaf number, leaf area, and dry and fresh weights of shoots and roots were investigated. Moreover, the plant colonization rates of AMF species were determined. The AMF species had positive effects on the plant growth and nutrient intake. Among the bean cultivars, Onceler and Terzibaba, and among the AMF species, G. mosseae had the best results for plant growth.
