Implication

Factorial experiment shows that plant growth-promoting microorganisms improve basil traits under salinity stress, suggesting effective cultivation strategies.

Key Points

  • The aim is to evaluate the effects of plant growth-promoting microorganisms on basil under salt stress.
  • Conducted a factorial greenhouse experiment with different salt concentrations (0, 30, 60, 90 mM NaCl) and treatments (AMF and PGPR inoculation).
  • Measured biochemical traits, essential oil content, and antioxidant activities in basil plants.
  • Analyzed the outcomes with completely randomized design and three replications.
  • Inoculation with AMF and PGPR significantly increased essential oil content and antioxidant enzyme activities.
  • Reduced electrolyte leakage, hydrogen peroxide, and malondialdehyde contents by approximately 25%, indicating better stress tolerance.
  • Highest increases in essential oil content recorded at 17.9% and 16.7% for specific treatments.
