Other claims from this paper (10)
- Observation Relative growth rate varied markedly and systematically over the maize life cycle.
- Observation The maize growth-rate curve had an initial fall and two subsidiary maxima on its descending limb.
- Mechanism Before assimilatory organs offset respiratory dry-weight loss, maize growth was negative or nil.
- Observation Leaf area per unit dry weight rose to a maximum during phase B-C.
- Observation Leaf area per unit dry weight declined continuously through phase C-F.
- Association The first subsidiary growth maximum coincided with male flower appearance.
- Association The second subsidiary growth maximum coincided with female flower appearance.
- Association Growth minima preceded the maxima and coincided with earliest flower development.
- Mechanism Earlier environmental conditions controlled the timing of growth maxima.
- Association Leaf area per dry weight corresponded with relative growth rate over the season.
