10.22376/ijpbs.2019.10.1.p1-12 Volume 2 Issue 4 2011 (October - December) The Root nodules of lessThan i greaterThan Cajanus Cajan lessThan /i greaterThan plant produced high amount of (35.56 ug/gm) of Indole acetic acid from Hg plants as compared to the N plant. The IAA was measured maximum from lessThan i greaterThan Rhizobium spp lessThan /i greaterThan . of lessThan i greaterThan C.cajan lessThan /i greaterThan plant at 24h, when the bacteria reached the stationary phase of growth. Mannitol & KNO3 preferred to be a good carbon and nitrogen source for IAA production in all N, Ng, H & Hg lessThan i greaterThan Rhizobium lessThan /i greaterThan strains. The possible relationship between the rhizobial IAA production & legume rhizobia symbioses in relation to stress is discussed.
