Other claims from this paper (10)
- Intervention effect Dormant pruning levels produced the same total shoot number and growth from one- and two-year-old apple branches.
- Observation Only a small amount of shoot growth occurred on two-year-old apple branches after terminals were headed back two-thirds.
- Intervention effect After-bloom shoot removal affected total apple shoot growth only when removed-shoot bases received 1% NAA.
- Intervention effect SADH reduced apple shoot growth by 18%.
- Association Apple yield was primarily associated with fruit load in the tree interior.
- Association Treatments increasing shoot growth on two-year-old apple branches reduced yield.
- Observation In 1974, apple treatment effects on yield were independent.
- Association Combinations of apple treatments that each increased yield had additive yield effects in 1974.
- Intervention effect Complete heading-back in 1974 reduced fruits per apple tree in 1975 because of spur loss.
- Observation Only 1974 shoot-removal treatments had a carry-over effect on apple shoot growth in 1975.
