Other claims from this paper (6)
- Intervention effect Pea, peanut and soybean seedling growth rose with photoperiod length to 16–20 hours.
- Intervention effect Aperiodic conditions caused no injury in pea, peanut or soybean.
- Observation Tomato dry matter production was optimal at an 18-hour photoperiod.
- Intervention effect Photoperiods longer than 20 hours caused interveinal chlorosis in tomato.
- Intervention effect A daily dark period of at least four hours prevented tomato chlorosis.
- Intervention effect A daily interval of markedly reduced light could prevent tomato chlorosis.
