Other claims from this paper (16)
- Intervention effect GA at anthesis produced almost 100% seedless berry set with or without SM.
- Intervention effect Later GA application lowered seedless berry set.
- Intervention effect GA with 2000 ppm SM produced almost 100% seedless berries when applied six days after anthesis.
- Observation Four days after anthesis, seedless berry set was lower in medium and large berries.
- Observation The reduction in seedlessness was stronger on weak than vigorous terminals.
- Intervention effect SM prevented reduced seedlessness on weak terminals.
- Intervention effect GA plus SM protected more strongly against physiological berry drop than GA alone.
- Intervention effect A second GA application further increased LL berry percentage.
- Observation Two applications from four days after anthesis yielded 15.9% LL berries.
- Observation Two applications from six days after anthesis yielded 24.2% LL berries.
- Intervention effect SM addition to GA lowered LL berry percentages to 0-3.7%.
- Intervention effect Treated berries colored earlier than controls.
- Intervention effect Treated berries were harvested about 10 days earlier than controls.
- Observation Treated fruit stalks showed moderate hardening.
- Observation Light berry set clusters showed berry loosening.
- Observation Seedless berries showed no cracking or drought-spot symptoms.
