Other claims from this paper (7)
- Observation At least two photoperiodic reactions contribute to the long day effect.
- Intervention effect The main light period reaction was more sensitive to near infrared and blue than red or green light.
- Intervention effect Red light antagonized the near infrared and blue light effect.
- Intervention effect At low intensities red light inhibited internode elongation more than blue light.
- Intervention effect At high intensities blue light inhibited elongation most.
- Intervention effect Near infrared or blue exposure antagonized red light inhibition of hypocotyl elongation in light grown gherkin.
- Intervention effect White or blue pre irradiation made red inhibition of dark grown gherkin hypocotyls stronger.
