Other claims from this paper (8)
- Intervention effect Ethephon alone at 100 or 200 mg/litre effectively thinned apples.
- Intervention effect NAA alone did not thin apples at any tested concentration.
- Intervention effect NAA with ethephon at 50 mg/ litre improved thinning over untreated control.
- Intervention effect NAA with ethephon at 50 mg/ litre did not significantly improve fruit weight and size.
- Intervention effect Ethephon alone at 100 mg/litre thinned as effectively as combinations with NAA.
- Intervention effect All treatments with ethephon at 100 mg/litre improved fruit weight and size.
- Intervention effect Ethephon at 200 mg/litre had no advantage over 100 mg/litre.
- Recommendation The authors recommend ethephon at 100 mg/litre for bloom thinning without added NAA.
