e0“increased fraction of blue 435 nm in combination with red light at 663 nm at high irradiance enhanced the physiology of lettuce (i.e., significantly increased assimilation rate, stomatal conductance and transpiration rate) and increased the yield while having no significant effect on antioxidant activity”

Other claims from this paper (7)
- Intervention effect At high irradiance, more blue 435 nm with red light increased lettuce assimilation, stomatal conductance and transpiration.
- Intervention effect At high irradiance the blue 435 nm and red 663 nm spectrum increased lettuce yield.
- Intervention effect At lower irradiance B435/R663 increased antioxidant activity over other spectra.
- Intervention effect In the second experiment LED spectra did not significantly affect lettuce physiology or yield.
- Intervention effect In the second experiment B450/R663 at 1.25 ± 0.1 strongly induced lettuce antioxidant activity.
- Intervention effect B450/R663 produced less antioxidant activity than B435/R663 1.25 ± 0.1 in the first experiment.
- Recommendation The authors conclude B435/R663 at 1.25 ± 0.1 improves lettuce yield and antioxidant activity.
