Root-zone oxygen supply improves lettuce photosynthetic function under waterlogging stress and promotes plant growth

Key Points

• Improved photosynthetic function in lettuce under waterlogging stress is linked to root-zone oxygen supply.
• Research demonstrates a notable increase in plant growth metrics, with specific emphasis on shoot and root development under challenging conditions.
• Observational analysis of lettuce plants indicates that adequate oxygen supply can mitigate the negative effects of waterlogging stress.
• These findings highlight the importance of oxygen levels in soil for optimizing crop yields, especially in flooded regions.
