- Intervention effect At PPF 500, increasing blue light from 11 to 28% reduced tomato growth by 22%.
- Intervention effect At PPF 500, increasing blue light from 11 to 28% reduced pepper growth by 14%.
- Intervention effect At PPF 500, increasing blue light had no statistically significant effect on radish growth.
- Intervention effect At PPF 500, increasing blue light had no statistically significant effect on soybean growth.
- Intervention effect At PPF 500, increasing blue light had no statistically significant effect on lettuce growth.
- Intervention effect At PPF 500, increasing blue light had no statistically significant effect on wheat growth.
- Intervention effect At PPF 200, increasing blue light reduced tomato growth by 41%; no other species responded.
- Intervention effect Increasing green light from 0 to 30% had a relatively small effect on growth, leaf area and net assimilation at low or high PPF.
- Intervention effect Growth of three of the seven species was not reduced by 93% green light compared with broad spectrum treatments.
- Mechanism The effects of blue light on growth were mediated by changes in leaf area and radiation capture.
- Association Blue light had minimal effects on whole-plant net assimilation.
- Mechanism Responses to low blue or high green light are consistent with a shade avoidance response.
