Restoration of Triticum aestivum Growth under Salt Stress by Phosphate-Solubilizing Bacterium Isolated from Southern Algeria

Salinity causes significant agricultural losses in many areas the world. Plant growth promoting bacteria (PGPB) are a promising solution to enhance plant and productivity under such stress conditions by different mechanisms, mainly phosphorous solubilization. This study aims improve wheat seedling salt halotolerant phosphorous-solubilizing bacterial strain. Soil sample was collected south of Algeria (Ghardaia), isolation carried out on nutrient agar (NA) at NaCl concentrations (300; 600 900 mM). The ability isolates solubilize inorganic 0; 300; mM determined. isolate that showed highest solubilization indexes selected identified as Pseudomonas azotoformans. Sterile (Triticum aestivum) seeds were inoculated this strain then sown soil (0; 100; 200; 300 Different parameters measured after 15 days. its capacity for (255.152 ± 0.01 µg/mL) NaCl, phytate mineralization (0.168 0.002 U/mL) 100 NaCl. amount soluble 49.42 0.36 ppm obtained Seed germination percentage, shoot root length fresh dry weights found be higher seedlings compared uninoculated ones. According study, use represents an important biotechnological approach restore levels saline soils promote salt-affected land.
