Other claims from this paper (5)
- Intervention effect Root pruning did not reduce growth over the two late-summer periods.
- Observation Compensatory growth redistribution did not account for the discrepancy between expected and observed pruning effects.
- Observation Pruned parts increased their growth rates relative to total growth, most markedly in roots.
- Observation The estimated function rate of pruned parts increased most for pruned leaves.
- Mechanism The authors conclude that neither leaves nor roots continuously limit growth and both usually operate below maximum efficiency.
