Other claims from this paper (11)
- Observation Apex transition to flowering made vegetative organ growth rate coefficients biphasic.
- Observation Stem elongation coefficient was lower in the vegetative phase than flowering phase.
- Association Stem elongation was temperature insensitive up to 20 °C in the vegetative phase.
- Association Stem elongation was temperature sensitive from 10 °C to 30 °C in flowering phase.
- Observation Plant, shoot and root dry weight growth coefficients were higher in the first phase.
- Association Plant, shoot and root growth coefficients increased with temperature to a maximum at 20 °C.
- Association Greater stem growth during flowering was compensated by slower shoot growth.
- Observation Tillers grew most rapidly, with successive tillers growing more rapidly.
- Mechanism Tiller growth accounted for the previously observed dominant growth of stems plus sheaths.
- Observation The slope change implies higher maximal vegetative plant growth coefficients than earlier estimates.
- Observation Under optimal conditions whole-plant growth coefficient appears limited to about half an organ coefficient.
