Abstract
In order to investigate the effect of mycorrhizal fungi on some physiological traits and antioxidant enzymes the tarragon plant under drought stress, this study was performed as a factorial experiment with two factors based on a completely randomized design with three repetitions. The first factor was drought stress at two levels including 100 and 50% field capacity (pot capacity) and the second factor was inoculation with mycorrhiza fungus from Glomus geus at 5 levels consisting of (G.hoi + G. mosseae, G. hoi + G. intraradices, G. mosseae + G. intraradices, G. hoi + G. mosseae + G. intraradices and no inoculation as control(. According to the results, the use of mycorrhizal fungi under drought stress conditions increased the activity of the enzymes of the ascorbate peroxidase, hydrogen peroxide, guaiacol peroxidase, catalase, superoxide dismutase as well as the amounts of malondialdehyde, total phenol and ascorbic acid in the leaves. The use of mycorrhiza fungus, unlike drought stress, increased potassium and phosphorus concentration. Application of the three mycorrhizal fungi combination (G. intraradices +G.hoi + G. mosseae) had a better effect on the physiological and biochemical traits than the control. The results of the research showed the positive effect of mycorrhizal fungus in increasing drought tolerance of tarragon plant and better control of free radicals produced under stress conditions.
