Other claims from this paper (8)
- Association Biological yield increased quadratically with leaf area index in wheat, with a larger response than grain yield (R2 0.46).
- Association Grain yield increased quadratically with leaf area index in wheat, with a smaller response than biological yield (R2 0.35).
- Association Above a leaf area index of 6.5-7.0 in wheat, biological yield and grain yield no longer increased.
- Association The response of grain number in wheat to changes in leaf area index was similar to the responses of biological yield and grain yield.
- Association In wheat, grain weight showed no remarkable relationship with leaf area index (R2 0.041, not significant).
- Association The relationship between leaf area index and grain yield in wheat was related to the relationship between flag leaf area index and grain number (R2 0.50).
- Association In wheat, grain weight was not significantly affected by flag leaf area index (R2 0.035).
- Mechanism Excessive leaf growth in wheat means leaf area cannot be used effectively beyond a certain level, because ear growth towards anthesis is negatively affected and insufficient grains develop.
