| Abstract | ||
| One of the beneficial effects of mycorrhizal symbiosis is declining the deleterious effects of environmental stresses in plants. Drought stress is one of the most important environmental stresses which is the results of our country climate. In this situation decline of mineral uptake especially phosphorus and zinc have more negative effects than lack of water in plant growth. Mycorrhizal fungi by increasing the mineral uptake can alleviate the part of plant growth and yield decline in drought stress. In order to evaluate the mycorrhizal fungi potential to decline the deleterious effects of drought stress , one greenhouse research with 10 fungal treatments in 3 levels of moisture including 8 , 16 and 32 %(w/w) and 4 replication for each treatments in completely randomized factorial was designed .Parameters such as shoot dry matter, root dry matter, colonization percentage and uptake of P, K Zn, Fe, Mn and Cu were determined. Results showed that moisture treatments had meaningful effect (P<0.01) on all parameters and fungal treatments also had meaningful effects (P<0.01) in colonization percentage and (P<0.05) on shoot dry matter and uptake of P, Zn and Fe .Three fungal species including Glomus mossea, Glomua intraradices and Glomus etunicatum were more effective than other species. | ||
