| Abstract:
Hormone levels were monitored along the dormancy period in flower buds of peach. Gibberellins A20 was characterized by gas chromatography-selected ion monitoring. Naringenin levels reached their maximum at leaf fall. Abscisic acid and indol 3 acetic acid levels increased during the time, reaching their maximum 2–4 weeks before blooming. The highest levels of Gibberellins A1/3 were found in june/july, when flower buds are not in development. | |
