Other claims from this paper (14)
- Association Regrowth amount was correlated with the size of the first growth cycle flush after pruning in sweet orange.
- Association Size of the first growth cycle flush after pruning was correlated with the diameter of the pruned branch in sweet orange.
- Observation No flowers were found on sweet orange regrowths 1 year after pruning.
- Observation Only 75% of sweet orange regrowths produced flowers 2 years after pruning.
- Observation Only 50% of sweet orange regrowths produced fruit 2 years after pruning.
- Intervention effect Low temperatures (18/13 C) for 8 weeks after pruning resulted in smaller first growth cycle flushes in sweet orange.
- Intervention effect After transfer to warm conditions the original height of sweet orange was not regained after three growth cycles.
- Intervention effect Cool conditions after the first or second growth cycles let sweet orange plants regain their original height after the third growth cycle.
- Observation Flowers could not be induced on the old wood of sweet orange after pruning.
- Observation Only few flowers were formed in the second growth cycle flushes of sweet orange.
- Intervention effect Many inflorescences were produced on third growth cycle flushes of sweet orange after inductive conditions (18/13 C) for 8 weeks.
- Intervention effect Light pruning of less vigorous sweet orange plants did not inhibit subsequent flowering.
- Mechanism Moderate pruning of sweet orange removes part of two crops, because regrowth flushes cannot flower until several growth cycles have formed.
- Association Pruning in autumn or winter would be expected to result in less vigorous sweet orange regrowth.
