Other claims from this paper (10)
- Association Light spectra and selenium forms interacted significantly for lettuce growth, foliar selenium and nitrate reduction.
- Association Leaf selenium concentration was negatively correlated with red light percentage.
- Intervention effect Selenate reduced nitrate more effectively than selenite.
- Intervention effect Selenate promoted nitrate reductase and glutamate synthase activities relative to selenite.
- Observation R/B=8 yielded the lowest nitrate content under both selenium forms.
- Observation R/B=8 yielded the highest plant biomass under both selenium forms.
- Association Light spectra significantly affected selenium root concentration factor and translocation factor.
- Association Light spectra caused marked variation in root and leaf selenium concentration.
- Intervention effect Red and blue LEDs significantly decreased foliar selenium concentration relative to fluorescent light.
- Recommendation The authors suggest light spectra can improve vegetable food quality through selenium distribution and accumulation.
