Isolation of Pseudomonas Strains with Potential for Protection of Soybean Plants against Saline Stress

Salinity is a major detrimental factor for plant growth and crop productivity that could be alleviated by the use of promoting bacteria (PGPB) with protective role in such stressful conditions. In this study, four native strains genus Pseudomonas were isolated from both strongly saline soil rhizosphere soybean plants grown slightly soil. These isolates able to tolerate high NaCl concentration, showed efficient adhesion biotic abiotic surfaces efficiently colonized these conditions, outperformed putida KT2440, strain known as good root colonizer different plants. Inoculation all improved seed germination vigor index, particularly one them also had positive effect on shoot length phenological state Our results suggest search classical promotion traits may not mandatory selecting putative PGPB. Instead, characteristics stress tolerance, adhesion, competitive colonization, should tested using types crops which will used.
