Overview

Comparative study reveals that bacterial treatments improve nutrient uptake and stress resilience in tomato seedlings grown in alkaline conditions, suggesting effective agricultural practices.

Key Points

  • This research aims to evaluate the effects of bacterial consortia on nutrient uptake and growth in tomato seedlings under alkaline soil stress.
  • Applied two bacterial strains separately and as a consortium to tomato seedlings in alkaline soil.
  • Conducted in vitro assessments of bacterial nutrient solubilization and PGPR characteristics.
  • Performed in vivo evaluations of seedling growth and biochemical responses to bacterial treatments.
  • Germination rates improved by 73.3% in treated seedlings compared to controls.
  • Protein and proline levels increased by 54.5% and 69.5%, respectively, after treatment.
  • Antioxidant activity enhanced by 50.7%, and phenolic and flavonoid content improved by 60.9% and 52.5%.
  • Activated nutrient-regulating genes linked to better root metabolism and stress resilience in treated plants.
