Other claims from this paper (6)
- Intervention effect Reduced light linearly decreased lettuce dry matter production.
- Intervention effect The lower nutrient nitrate level reduced lettuce dry mass yield.
- Observation Maximum lettuce nitrate accumulation was 966.3 mg kg-1 fresh mass at PPF 118 μmol/m²/s and 140 mg L-1 N-NO3-1.
- Observation Minimum lettuce nitrate accumulation was 200 mg kg-1 at PPF 455 μmol/m²/s and 70 mg L-1 N-NO3-1.
- Intervention effect Reducing nutrient nitrate from 140 to 70 mg L-1 reduced shoot nitrate accumulation.
- Intervention effect The same nitrate reduction significantly reduced leaf area.
