Abstract :

In order to evaluate the effect of arbuscular mycorrhizal fungi under drought stress on linseed …, an experiment was conducted as split-plot arrangement based on RCBD with three replications at the Research Station of Faculty of Agriculture in Shahrekord University in 2013. Drought stress at four levels of without stress, moderate, the average, and severe stress as the main factor and inoculation with Glomus intraradices, Glomus mosseae and no inoculation as sub factor were evaluated. The results showed that the effect of mycorrhiza inoculation and drought stress treatment had significant effect on all measured traits. The interactions between mycorrhiza and drought stress treatments were significant on capsule number per plant and seed number per capsule. Based on the results in this experiment inoculation with mycorrhizal fungi, increased grain yield and 1000 seeds weight 27% and 10.6% respectively compare to no inoculation treatment. Based on resulted in this experiment symbiosis of flax with of arbuscular mycorrhizal fungi caused increased in all traits.
