Inoculation of plant growth promoting bacteria (PGPB) was found to be more promising to induce growth of paddy plants under lower and moderate salinity levels. PGPB protects the plants from salinity injury by increasing biomass content, photosynthetic activity and antioxidant enzymes acid phosphatase and glutathione reductase. This study also states that PGPB helps in decrement of lipid peroxidation, plays an important role in regulation of growth for positive adaptation of plants to salt stress. However with increase in soil salinity the glutathione reductase activity decreased in non-inoculated plants. The present study shows that inoculation of paddy (Oryza sativa) with root associated bacteria could provide salt tolerant ability to paddy plants as these isolates also remain associated with root and root is the plant part affected first by salinity, so it serve as a useful tool for alleviating salinity stress.
