- Intervention effect Pruning 28% of roots reduced net photosynthesis by 35% after one day.
- Intervention effect Pruning 59% of roots reduced net photosynthesis by 47% after one day.
- Intervention effect Pruning 28% of roots reduced transpiration by 29% after one day.
- Intervention effect Pruning 59% of roots reduced transpiration by 45% after one day.
- Intervention effect Root pruning significantly reduced leaf water potential for six hours.
- Observation Leaf water potential recovery was apparent after one day.
- Intervention effect Pruning 10% of roots had no effect on photosynthesis, transpiration or water potential.
- Association Shoot growth rates declined with greater root pruning severity.
- Observation Shoot extension had its greatest reduction during weeks two and three after pruning.
- Observation Shoot growth rates increased during week four.
- Intervention effect Shoot diameter increase was suppressed for two weeks.
- Intervention effect New leaves after 28% or 59% root pruning were smaller than unpruned leaves.
- Intervention effect New leaves after 28% or 59% root pruning had increased specific leaf weight.
- Intervention effect Previously expanded leaves were unaffected by root pruning.
- Association Greater pruning severity reduced fresh weight of leaves and current shoots by 45%.
- Intervention effect Older tree parts were not influenced by pruning severity.
- Intervention effect Total root fresh weight did not differ four weeks after pruning.
- Intervention effect Pruned trees had more small roots close to the stem.
- Intervention effect Pruned trees had fewer small roots beyond 5 cm from the stem.
