Summary
This research demonstrates how beneficial bacteria can be used to naturally protect oak tree seedlings from disease while helping them grow better. The study found that a specific bacterial strain (B. velezensis CE 100) could both fight off harmful fungi and promote healthier plant growth, offering an environmentally friendly alternative to chemical treatments.
Impacts on everyday life:
• Provides a safer, chemical-free method for growing healthy forest trees
• Helps ensure more successful reforestation efforts for environmental conservation
• Demonstrates sustainable alternatives to chemical pesticides in plant cultivation
• Contributes to more efficient and eco-friendly forestry practices
• Could lead to better survival rates for newly planted trees in urban and rural settings
Background
Quercus acutissima (Oak) seedlings are important for reforestation but are susceptible to leaf blight disease caused by Pestalotiopsis maculans. Traditional chemical fungicide treatments can lead to resistance and environmental concerns. Plant growth-promoting bacteria offer a potential eco-friendly alternative for disease control and growth enhancement.
Objective
To investigate the biocontrol potential of Bacillus velezensis CE 100 against leaf blight disease caused by P. maculans and evaluate its growth promotion effects on Q. acutissima container seedlings.
Results
B. velezensis CE 100 inhibited P. maculans mycelial growth by 54.94% through production of cell wall degrading enzymes. Bacterial inoculation increased seedling survival rates by 1.6-fold and 1.3-fold compared to chemical fertilizer and control treatments respectively. The treatment also enhanced root development, nutrient uptake, chlorophyll content, and total biomass production by 1.3-fold and 2.2-fold versus chemical fertilizer and control groups.
Conclusion
B. velezensis CE 100 demonstrated effective biological control of leaf blight disease while simultaneously promoting growth and biomass production in Q. acutissima container seedlings. The results suggest this eco-friendly bacterial treatment could be a viable alternative to chemical treatments in forest nursery production.
