Other claims from this paper (10)
- Observation Spring wheat mature leaf area increased through leaf 5, then varied with genotype and environment.
- Intervention effect Later leaves became progressively smaller under low nitrogen, mainly through reduced length.
- Intervention effect Later leaves became progressively smaller under extended photoperiod, mainly through length change.
- Observation Winter genotype mature leaf dimensions increased with leaf number throughout the study.
- Intervention effect Winter genotype mature leaf dimensions were not markedly affected by photoperiod.
- Intervention effect After leaf 5, winter genotype leaves were smaller at low nitrogen.
- Association First-leaf size varied among sowing dates, partly owing to temperature.
- Association Successive-leaf regression coefficients varied among sowing dates, partly owing to temperature.
- Method / resource A logarithmic predecessor-leaf function estimated potential size at lowermost leaf positions.
- Method / resource That relationship can calculate actual leaf size when environmental and assimilate supply factors are included.
