Growth and Metabolic Response of Glycine max to the Plant Growth-Promoting Enterobacter Delta PSK and Bradyrhizobium japonicum Under Salinity Stress

Abstract This study was designed to test the ability of some plant growth-promoting bacteria adverse effects salinity on soybean growth. The effect Bacillus MAP3 and Enterobacter Delta PSK, along with Bradyrhizobium japonicum studied at two levels NaCl salinization (50 100 mM). physical growth parameters bacterized (21 days old), particularly plants co-inoculated + were significantly enhanced compared control plants. shoot length, leaf area, root chlorophyll a content increased by 49.58%, 78.58%, 20.19%, 57.35%, respectively, indicating promoting activity this bacterial combination. After 19 following onset stress, retarded in controls improved due treatments, especially DeltaPSK, which values all regardless level. Additionally, electrolyte leakage, amounts malondialdehyde hydrogen peroxide decreased considerably combined treatment . Overall, combination PSK original symbiont B. under salt mitigate osmotic stress. strain yield should be further evaluated pave way for its use as biofertilizer japonicum,
