ASSESSMENT OF THE EFFECT OF HALO?TOLERANT BACTERIUM ON PLANT GROWTH PROMOTION

Abstract

Author(s): S. Anbumalar*, P. Ashokuma

A total of 12 halobacterial strains were isolated from soil samples of various salterns in Tamilnadu, India and screened their plant growth promoting activity. All the isolates were produce Indole Acetic Acid (IAA), Ammonia and 7isolates produced Hydrogen Cyanide (HCN). Siderophore production and phosphate utilization were negative. In this present study only one isolate (M5) showed good growth in halophilic medium and plant growth promoting activities such as IAA, HCN and Ammonia production. The plant growth promotion effects was tested in pot trials with various crops like Cotton, Jatropa, Lady’s finger and Sorghum. Selected isolate significantly increased the plant shoot length and seed germination percentage in pot conditions compared to control. Further this isolate was identified as Chromohalobactersalexigensbased on 16s rRNA sequencing.
