Özet

Seasonal changes of gibberellins (GAs), the cytokinin trans-zeatin (t-Z), the auxin indole-3-acetic acid (IAA) and abscisic acid (ABA) in Rosa canina L. were analyzed by high performance liquid chromatography (HPLC). The concentration of GAs increased during the period of rapid growth in April and May, and coincided with the time of the increase in t-Z concentration. The concentration of IAA decreased slightly from January until March, increased strongly in April and then decreased again after the cessation of rapid growth. The concentration of ABA decreased steadily from January to May, followed by a slight increase which became most notable during the fruiting period, reaching a peak in January.
