Abstract

AZOSPIRILLUM brasillense is one of the nitrogen fixing microorganisms which in association with root of cereals and grasses, enhances growth and development of plants. In this research WHEAT seeds (T.aestivum) of three cultivars (Ghods, Roshan and Omid) were inoculated with two AZOSPIRILLUM strains (Sp7 and Do1) and grown according to airoponic method. Inoculation increased density and length of ROOT HAIRS and also in several cases were caused root hair DEFORMATION. These changes were directly dependent on the strain-cultivar combination. Strain Do1 induced the greatest density and branching of ROOT HAIRS in cv. Ghods, whereas strain Sp7 stimulated the highest density and DEFORMATION of ROOT HAIRS in cv. Roshan. The response of cv. Omid was less that the other cultivars. The effects of AZOSPIRILLUM inoculation were mimictable by authentic indole acetic acid. The presence of IAA in culture filtrate of AZOSPIRILLUM strains (Sp7, Do1) was confirmed by thin layer chromatography. Therefore, this study has veen demonstrated the important role of IAA in interaction between AZOSPIRILLUM and WHEAT root and also density and defromation of ROOT HAIRS.
