Other claims from this paper (18)
- Intervention effect At equivalent crop load, NAA tended to reduce fruit size.
- Intervention effect At equivalent crop load, BA tended to increase fruit size.
- Intervention effect Combined NAA and BA led to excessive pygmy and small fruit in Delicious and Fuji.
- Intervention effect BA at king bloom plus NAAm at petal fall increased small fruit 3.3-fold versus BA alone.
- Intervention effect BA at king bloom plus NAAm at petal fall increased small fruit relative to NAAm alone.
- Intervention effect BA at king bloom oversprayed with NAA at 10 to 12 mm gave similar small fruit results.
- Intervention effect NAA oversprayed with BA inhibited fruit growth most at 10 to 12 mm king fruit diameter.
- Intervention effect NAA oversprayed with BA at 18 mm king fruit diameter had no significant effect on fruit growth.
- Intervention effect Treatment at 5 to 6 mm had intermediate fruit growth inhibition.
- Intervention effect Treatment at 5 to 6 mm overthinned trees.
- Association NAA plus BA growth inhibition in Delicious and Fuji did not depend on crop load.
- Intervention effect NAA plus BA crop load was similar or less than NAA or BA alone.
- Intervention effect NAA plus BA produced 2.5- to 5-fold more small fruit than NAA or BA alone.
- Intervention effect NAA plus BA increased fruit per cluster, many failing to develop fully.
- Intervention effect Increasing BA to NAA ratio increased small fruit formation.
- Intervention effect GA 4+7 presence in BA formulations did not significantly alter the NAA plus BA response.
- Intervention effect Combined NAA and BA did not inhibit growth in Golden Delicious and Jonagold.
- Intervention effect Combined NAA and BA increased growth in Elstar and Gala relative to untreated control.
