Seeds of Macrotyloma uniflorum were fed with various concentrations of PEG ranging from 5 to 25% during germination and continued till 45 days after germination on alternate days to induce water stress. Inoculums of Glomus mosseae and G. fasciculalum were added to the soil in pot experiment before sowing the seeds. Nodule number, mass, leghaemoglobin and proline contents were estimated in 45 days old plants of unstressed, induced stressed, unstressed AMF treated and stressed AM fungal treated. Observations revealed that AM fungal association improves the number and mass of nodules along with enhanced contents of leghaemoglobin under induced stressed condition. Content of proline in leaves is increased under induced stress in both mycorrhizal and non mycorrhizal plants. However the increase is more evident in non mycorrhizal plants than AM fungal treated plants under induced stress indicating better osmotic adjustment by AM symbiosis. Among the two AM fungal species, G. mosseae is more compatible with the host by improving all the parameters studied than G. fasciculalum inoculated plants indicating its host specificity. The significance of AM fungal association in the process of nodulation of legumes is discussed.
