e0“BA thinned apple (Malus domestica Borkh.) fruits when applied to either the leaves or the fruit, although it was much more effective when applied to the leaves”

Other claims from this paper (10)
- Intervention effect BA thinned apple fruit when applied directly to fruit, less effectively than leaf application.
- Intervention effect Direct fruit application of BA increased fruit size independently of crop-load reduction.
- Intervention effect BA on one fruit did not alter abscission, size, or characteristics of the adjacent untreated fruit.
- Intervention effect BA reduced flesh calcium in treated fruit in inverse proportion to increased size.
- Observation More than 60% of fruit-applied BA was absorbed in 24 hours.
- Association Fruit absorption of BA exceeded penetration through either leaf surface.
- Intervention effect Thinning BA treatments increased ethylene production linearly in leaves and fruit after 24 hours.
- Mechanism Authors considered the ethylene increase too small to be the primary thinning cause.
- Intervention effect BA thinned spurs with two or three fruit more than single-fruit spurs.
- Intervention effect BA did not selectively thin clusters to one fruit.
