- Intervention effect Removing a bark ring increased initial fruit set versus normal spurs.
- Intervention effect Combining ringing and complete leaf removal caused complete fruit loss.
- Intervention effect Ringing reduced final fruit set.
- Intervention effect Reducing spur leaf area reduced final fruit set.
- Intervention effect Stigma injury reduced final fruit set.
- Intervention effect Undefoliated, unringed spurs with developing bourse shoots produced the greatest fruit number and weight.
- Intervention effect Ringing had no later-season effect on net photosynthesis.
- Intervention effect Bourse shoot presence reduced spur-leaf photosynthesis in early June.
- Mechanism Spur leaves locally influenced fruit set, ultimate fruit size, and fruit calcium.
