Microbial Isolates for Enhancement of Seed Germination

Bacteria that colonize plant roots and promote plant growth are referred to as Plant Growth- Promoting Rhizhobacteria (PGPR). Rhizobium bacterial isolated from soil samples collected from prathyusa college garden soil. Isolated organisms names as PEC 1 and PEC 2, further used for seed germination efficiency with vigor index. The emergence of seedlings, from the seed at a height of 2 mm was treated as germination. This was carefully recorded for 120 hours. In the present study 2 types of plant growth promoter rhizobium (PGPR) strains were isolated and used as inoculums PEC1 and PEC2. The present study indicates that the germination efficiency of the bhendi seeds is influenced by the rhizobium isolated from the Prathyusha college garden soil. In total effective two isolated sample PEC 1 and PEC 2 showed higher influence in germination efficiency, germination co efficiency and vital index.
