Other claims from this paper (12)
- Observation Seed auxin-like activity hardly differed between 16 and 60 days after full bloom in both cultivars.
- Intervention effect MCPB spray slightly reduced fruit abscission under shading.
- Intervention effect Shading increased seed abortion.
- Mechanism Most fruits were small under the shading treatment, attributed to increased seed abortion.
- Observation Seed gibberellin-like substances increased from 23 days after full bloom in Fuji.
- Observation Seed gibberellin-like substances increased from 42 days after full bloom in Starking Delicious when early fruit drop ceased.
- Intervention effect GA3+GA4 spray promoted fruit growth despite shading-induced seed abortion.
- Association The authors associate seed gibberellins closely with early fruit drop and fruit growth.
- Observation Fuji seed cytokinin-like substances peaked at 25 days after full bloom, six days earlier than Starking Delicious.
- Intervention effect BA spraying at 19 days after full bloom increased fruit abscission.
- Intervention effect Ethylene evolution from fruit increased after BA spray.
- Mechanism The authors suggest increased ethylene evolution may have influenced BA-associated fruit abscission.
