Salt stress is an important environmental stress. Plants cope with salt stress with different strategies. In this study the effects of 2 different arbuscular mycorrhiza species (Glomus mosseae and G. intraradices) on some biochemical parameters in pepper plants (Capsicum annuum L. cv. Cumaovasi) exposed to long term salt stress were studied. It was found that mycorrhizal inoculation increased RWC, P, total chlorophyll, and carotenoid content of pepper plants during salt application. The enzyme activities changed depending on the enzyme and salt stress application. The lowest MDA content was found in the plants inoculated with G. intraradices; however, there was no significant difference between the NaCl applications. It was found that plants inoculated with G. intraradices had less lipid peroxidation, and therefore it can be said that these plants have an advantage under salt stress.
