Other claims from this paper (13)
- Intervention effect NAA significantly reduced preharvest drop on only one sample date in only one of three trials.
- Intervention effect AVG on otherwise untreated trees significantly delayed drop compared with controls in two of three trials.
- Intervention effect AVG at 124 gram a.i./ha resulted in better fruit firmness out of storage.
- Intervention effect Earlier harvest after ethephon treatment resulted in smaller fruit size.
- Intervention effect Ethephon on AVG-treated trees significantly enhanced red color.
- Intervention effect Ethephon on AVG-treated trees also significantly accelerated drop.
- Intervention effect Drop on AVG-treated trees sprayed with ethephon was reduced compared with ethephon-only treatment.
- Intervention effect Late summer pruning significantly accelerated red color development.
- Intervention effect Late summer pruning significantly accelerated drop.
- Intervention effect Late summer pruning significantly accelerated ripening.
- Intervention effect Pruning on 16 Aug. 1996 significantly accelerated drop compared with pruning on 1 Aug. 1996.
- Intervention effect Combining AVG application and pruning on 16 Aug. 1996 resulted in improved color compared with controls.
- Intervention effect Combining AVG application and pruning on 16 Aug. 1996 did not increase drop compared with controls.
