Other claims from this paper (17)
- Association Vessel size and plant number greatly influenced long-day flowering at 20°C.
- Association Smaller vessels gave greater flowering response.
- Association Nutrient solution volume per plant was not decisive for long-day flowering.
- Intervention effect Plants in 200-ml beakers flowered.
- Intervention effect Plants in 5,000-ml vessels did not.
- Association Long-day flowering coincided with suppressed root elongation.
- Association Long-day flowering did not accompany a decrease in rate at which the leaf primordia appeared.
- Intervention effect Aeration of the nutrient solution promoted root elongation.
- Intervention effect Aeration of the nutrient solution inhibited long-day flowering.
- Intervention effect culture in vermiculite promoted root elongation.
- Intervention effect culture in vermiculite inhibited long-day flowering.
- Mechanism Suppression of root elongation seems necessary for long-day flowering.
- Intervention effect Removal of roots suppressed long-day flowering in small vessels.
- Intervention effect Removal of cotyledons suppressed long-day flowering in small vessels.
- Intervention effect At 24°C, suppression of root elongation in a small vessel did not induce long-day flowering.
- Intervention effect At 24°C, short-day treatment induced flowering.
- Intervention effect At 24°C, short-day treatment did not suppress root elongation.
