Drought is one of the most important environmental stresses that adversely affect plant growth and crop production will In order to study a factorial randomized complete block design with three replications in greenhouse Ardabil University mohaghegh was conducted in 2013. Treatments were water stress at three levels: 35%, 55% and 75% field capacity and seed inoculated with mycorrhiza growth promoters (Glomus Mosseae), Rhizobium (Sinorhizobium meliloti), a mixture of both experienced and non-inoculated as results showed main effects and interaction between water stress and seed inoculation rates at 1% level of proline, soluble sugar, membrane stability, osmotic potential, plant height and leaf area was significantly influence of alfalfa, however lysine and methionine levels were changed only main effects. Increase the stiffness of proline, soluble sugar and decrease osmotic potential, membrane stability, lysine, stem height and leaf area were. Growth stimuli by increasing the production of metabolites and increased osmotic potential and membrane stability reduces the damaging effects of stress and increase plant height and leaf area were of alfalfa. Mycorrhiza and Rhizobium have performed better in most traits, but simultaneously they always showed the highest value. Also according to the regression equations in tension 85% proline and methionine had the highest share in the determination of cell water and the portion of the methionine reduces stress and enhances the contribution of soluble sugars and proline in determining the relative water content increases this increases the osmotic potential contribution in determining the relative water content in cells. Rhizobium and mycorrhiza mixture of proline and methionine, the highest share in determining the relative water content of the cells showed. Changes in leaf water content of a quadratic equation, but stem cells compared with less leaf area affected by the water content of cells Generally use a mixture of mycorrhiza and Rhizobium is always the best treatment for reducing stress have to show that there is a relationship between them Synvzhysty
