Other claims from this paper (13)
- Observation Peach seed germination at 20°C remained below 20% after up to 35 days at 5°C.
- Observation Germination exceeded 40% after more than 42 days at 5°C.
- Observation Four zones of gibberellin-like activity occurred in seed extracts.
- Observation Gibberellin-like activity stayed low through 28 days at 5°C.
- Observation Gibberellin-like activity significantly increased in three zones after 35 days.
- Observation Gibberellin-like activity increased in the fourth zone after 49 days.
- Observation Seeds germinated at 5°C after 63 days.
- Observation At 20°C, germination percentage and gibberellin-like activity stayed low.
- Intervention effect Paclobutrazol did not substantially reduce seed germination.
- Intervention effect Paclobutrazol prevented the rise in gibberellin-like activity.
- Intervention effect Paclobutrazol-treated seeds took longer to germinate after transfer to 20°C.
- Observation Paclobutrazol-treated seedlings were dwarfed.
- Association Authors associate gibberellin-like activity chiefly with normal seedling growth and development.
