Other claims from this paper (9)
- Intervention effect Prebloom SADH spray on Kyoho clusters increased the set of seeded berries, as effectively as foliar treatment or shoot pinching.
- Intervention effect Spraying clusters without prebloom shoot inhibition had no inhibitory effect on shoot growth during bloom and set.
- Intervention effect CCC applied at 200 ppm to Muscat of Alexandria clusters gave nearly the same increase in berry set as seen with SADH.
- Intervention effect Growth retardant applications to clusters or leaves distinctly reduced gibberellin activity in florets at the beginning of bloom.
- Intervention effect Shoot pinching raised gibberellin activity in florets of Muscat of Alexandria.
- Intervention effect Shoot pinching did not affect gibberellin activity in florets of Kyoho.
- Intervention effect Shoot pinching markedly enhanced cytokinin activity in florets in both cultivars.
- Mechanism Reduction of shoot growth is not essential for growth retardants to promote the set of seeded berries.
- Mechanism Increased cytokinin activity in florets induced by the chemicals is causally associated with the promoted berry set.
