Synergistic Effect of Plant-Growth-Promoting Rhizobacteria Improves Strawberry Growth and Flowering with Soil Salinization and Increased Atmospheric CO2 Levels and Temperature Conditions

Biofertilization with plant-growth-promoting rhizobacteria (PGPR) can positively affect the growth and health of host plants reinforce their tolerance stressors. Here, we investigate use isolated PGPR consortia from halophytes to improve strawberry flowering performance under saline elevated CO2 temperature conditions. Growth, flower bud production, photosynthetic apparatus response were determined in grown at 0 85 mmol L?1 NaCl two atmospheric CO2-temperature combinations (400/700 ppm 25/+4 °C, respectively). improved plant independently salinity conditions, ambient 25 while bacterial inoculation only had a positive effect on presence salt high +4 °C. Biofertilizers 1 3 generated largest biomass strawberries 400 NaCl, respectively, biofertilizer did so an atmosphere enriched The was mediated by strain PGP properties, rather than improvement rate plants. Furthermore, biofertilizers 2 increased number buds absence salt, 4 for salt-inoculated There no production Finally, concluded that depended type This highlights importance developing studies considering stress interaction assess real potential biofertilizers.
